"I just want an ice pier, but it's hard to find one." Call your girlfriend to make you an ice pier, and you say I'll succeed in doing so? ”
In the past two days, Xiaobian's brain has been "brushed" by this song
What a lovely ice pier, I want to have it right away
But Xiaobian can't buy it
Don't be frustrated if you can't buy it
After all, we still have aviation people's love to use good things
Today, I would like to introduce you to 6 models of labor tools that aviation people love to use
Solve 90% of everyone's work problems
Fitter sharps
"Friend, are you still feeling powerless for the crooked and crooked bushing?" Are you still worried about smashing the wood chips on the bushing? Still exhausted by repeated rework for bushing press in and out? "It is time to show a professional tool for bushing pressing that was independently developed by the large aluminum alloy component production workshop of the Shenfei CNC processing plant of the aviation industry - the directional pressing tool. The tooling contains a positioning mandrel, a detent pad, a threaded drive rod, through the positioning of the mandrel, it is easy to find the inner hole of the bushing in the process of pressing the sleeve, which is a stable and reliable tool for pressing the sleeve.
Directional press sleeve tooling
Directional press sleeve tooling is simple to use and easy to operate. When using, the sleeve mandrel is first inserted into the inner hole of the bushing as the main positioning part of the bushing. Secondly, the base plane is fitted to the surface of the platen substrate, and then the bolting mechanism is rotated, and the bushing can be pressed into the bottom hole of the part at a uniform speed.
The use of directional press-sleeve tooling, on the one hand, can effectively constrain the axis direction of the bushing pressing, to avoid "east to west crooked"; on the other hand, through its own bolt transmission mechanism, the bushing can be easily and uniformly pressed into the bottom hole, to avoid the problems of workpiece deformation, scratches and cracks caused by uneven manual pressure during the installation of the bushing.

Aircraft maintenance reflective vest
"When it comes to scientific research and test aircraft maintenance, what comes to mind?" "Probably a handsome back wearing a reflective vest, holding a baton, and directing an airplane!"
Just like everyone's stereotype of the aircraft maintenance position, the test aircraft maintenance vest is an indispensable labor tool for the aircraft maintenance worker. In 2021, the Aircraft Maintenance Department of the Aviation Industry Test Flight Center will carry out the reform of the maintenance and support mode, and launch a new series of aircraft maintenance reflective vests in order to ensure the long-term quality and safety of the aircraft maintenance work. The Helicopter Independent Squadron is a pilot unit, spearheading the use of a new series of aircraft maintenance vests. Since then, on the occasion of the plateau desert, the top of the snow-capped mountains, and the sea and sky, the reflective vests have shone brightly in every test flight field.
Considering the practical needs of the daily work of the test aircraft, the reflective vest is professionally divided according to different functions, and the appearance, function and storage capacity have been improved. Reflective vests are different colors to help identify professionals and fulfill their duties.
Blue represents mandatory inspectors, planning/system/configuration engineers, and release personnel, fluorescent orange represents mechanics, and fluorescent green represents mechanical, ad hoc, avionics, and ordnance-capable workers.
Orange reflective vest
The increase in reflective area has played a role in ensuring the personal safety of the aircraft maintenance, and at the same time has played a warning role for the relevant staff in the security task. Reflective vests also add storage and are paired with a Velcro closure.
During the scientific research test flight mission, the aircraft maintenance said: "I have a new reflective vest, like wearing a battle robe." This is a full sense of ceremony for engaging in test aircraft maintenance, shouldering a great sense of mission to carry out test flight tasks, and carrying a lofty sense of awe in the face of quality and safety. ”
Wearing different colors of reflective vests, the maintenance of the aircraft, adhere to the quality and safety red line, each perform their duties, do their own responsibilities, each in its place, cooperate with each other, work together, improve the efficiency of scientific research test flights.

Puller for lathe workers
"I'm a person who loves to share. Today I recommend a good thing that has been used countless times and will also be 'infinitely repurchased' - CNC lathe puller. ”
There are three characteristics of the material puller, one is easy to use, the other is convenient, and the third is to save time. As a CNC lathe worker, he mainly undertakes the processing tasks of parts in the hydraulic, fuel and environmental control system departments.
During the "14th Five-Year Plan" period, the demand for a certain product increased sharply, which put forward higher requirements for the quality and efficiency of each processor's work. A puller is a device that can be mounted on the turret of a CNC lathe. After cutting the bar stock, the puller pulls out the remaining bar stock and then proceeds to the next part. No need to manually measure the pulling distance, the use of CNC lathe program pine chuck pull bar material, pull out length by CNC program control, the spring of the puller has elasticity, can pull different diameters of bar stock.
The puller pulls out the remaining bar stock
The puller is like another "hand" of the processor in the machine tool, improving the degree of automation of the CNC lathe, without the need for the processor to manually and frequently load and unload, to achieve continuous turning cycle, greatly improving the processing efficiency. Small advances in the extractor as a tool have taken a big step forward in lean management. Processors will discover more good things to use and popularize more humanized tools.

A paint retouching tool for rivets
"The good things I recommend today are definitely good things that people love at first sight in the aviation manufacturing profession."
During the aircraft manufacturing process, it is often encountered that some parts cannot be painted. What to do? Are you still brushing with your own little hands? Can re-painting over and over again ensure the specification? Today I recommend a fastener repainting tool on the aircraft, which will solve your problem once.
Fastener repainting tool
After analyzing the bottleneck problems in the ARJ21 aircraft manufacturing process, Jiang Biying modeled and tested to make a paint tool.
The tool structure is simple, the main structure refers to the pen working form, and the form of pressing out paint can effectively control the amount of paint and avoid waste. The head of the tool is a magic rub, which can make the paint coating evenly and achieve the effect of full coverage after contacting the fastener.
The tool is easy to use, only the paint used is poured into the liquid carrier bottle and the paint nozzle is installed. The paint nozzle is repeatedly pressed against the end of the fastener and rotated accordingly to complete the painting work of the fastener end. Before using the tool, it took at least 4 days for 2 people to paint the fasteners of the ARJ21 fuselage at the same time; now it takes only 2 days for 2 people to work at the same time to complete the painting of the fuselage fasteners.
Use the paint tool to brush the fasteners, and the results are good.
For rivets, the engineering requirements can be met with a brush, and the failure rate is reduced to 10%. The lacquer cover is continuously smooth, just as beautiful as the sugar coating of the rock sugar gourd. At present, the tool has applied for the Science and Technology Micro Innovation Award of the General Manager of AVIC Xifei, and at the same time applied for a national patent, which will be promoted to the application of fastener painting of all components of the fuselage and wing of the ARJ21 project.

Composite stopper ruler
"Making composites is like spreading pancakes. Whether the pancakes are spread well or not, it is the key to spread the cakes evenly and evenly. The first step of gluing is like spreading pancakes, and the molten resin is evenly applied to the release paper, and this step is complete. ”
Of course, there are also "billions of dots" details here. How can you evenly apply more than ten grams, about one tablespoon of resin, on 1 square meter of release paper about 1 table? How can it be applied continuously for thousands of meters? This requires the use of a good tool necessary for the film and prepreg section - the stopper ruler.
Plug ruler
Before production, the operator took out a stopper ruler, found the thinnest sheet of 20 microns, inserted it to check the gap, and made sure that each place was only as thin as two strands of hair. Add the resin, start the equipment, and a roll of thin and uniform resin film is ready.

Lithography database management information system
There are many micro-electromechanical system products of the Aviation Industry Automation Institute, the process is complex, and each type of product requires multiple lithographs for graphic transposition in the process of tape-out (like an assembly line through a series of process steps to manufacture chips).
Lithography mask plates are a key physical medium for transferring design graphics to wafer products. At present, the on-site production and development of the self-control institute includes more than 150 lithography plates, and the lithography process involves an average of about 15 plate changes per day. Therefore, the management and storage of on-site lithographs will directly affect the efficiency of mold change and the correctness of graphics in the production line. For the more than 1,000 lithography plates in the updated reserve, it has become more difficult to find and use them again.
Monolithic explicit storage
These problems can not be difficult for the small partners in the front line of scientific research. They use their brains to develop on-site management systems by taking advantage of informatization. They first designed and produced their own monolithic lithograph storage shelf, and customized the index serial number for daily production, development of lithography storage, and rapid index selection. Then sort out and rectify the storage status of the on-site lithography, compile and develop the stand-alone version of the "Lithography Database Management Information System" software, and create an on-site management system for the storage, collection and return of the lithography version, which is used for the backup storage of the old version after the update, and at the same time facilitates indexing and searching.
Through this self-developed software tool, optical researchers will be lithography production, acceptance of the library, use, return, disable the elimination of the whole process, all into the information database management. The most powerful thing is that the lithography index number corresponds to the process of the process flow list one by one, and the index number can realize "instant query, instant use, and instant home", realize process error prevention, and increase the lithography switching efficiency by more than 5 times.
