Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts production equipment, specifically to an air-filling device for the production of automotive shock absorbers. Background Technology

[0002] The term "shock absorber" is a common term in the automotive chassis industry. An automotive shock absorber is actually a vibration damper. Shock absorbers are used not only in the suspension but also in other parts of the car. At the bottom of the shock absorber cylinder is a floating piston, which divides the working chamber into three parts. High-pressure nitrogen is filled into the chamber formed by the floating piston and one end of the cylinder. Above the floating piston is the shock absorber fluid. A large-section sealing ring is installed on the floating piston to completely separate the oil and gas, forming a sealed piston. The working piston is equipped with a compression valve and an extension valve whose cross-sectional area changes according to its speed. Both valves consist of a set of spring steel plates of the same thickness but different diameters, arranged from largest to smallest. Filling the automotive shock absorber with high-pressure nitrogen requires a filling device.

[0003] Currently, in the use of inflation equipment, due to its simple structure, it is not convenient to fix car shock absorbers. It only uses a single slot for positioning and is not convenient to load car shock absorbers, making it inconvenient to use. At the same time, after the car shock absorbers are inflated, they are easy to get stuck in the slot, making it difficult to remove the car shock absorbers, which reduces the efficiency of the inflation equipment. Therefore, we have proposed an inflation equipment for the production of car shock absorbers. Utility Model Content

[0036] In summary, the shock absorber is limited by the first positioning groove 360 ​​and the connecting end of the shock absorber is positioned by the second positioning groove 361. Then, the second electric telescopic rod 320 extends to drive the two clamping blocks 330 to clamp and fix the shock absorber.

[0037] In summary, the linear motor 120 drives the moving plate 300 out of the housing 200, and the air pump 370 fills the through hole 362 with gas, which is then introduced into the second positioning groove 361 through the through hole 362. This causes the shock absorber in the first positioning groove 360 ​​to move upward under the influence of air pressure, thereby facilitating the removal of the car shock absorber and improving the efficiency of the inflation equipment.

[0038] In practical use, those skilled in the art first manually open the door 260 and operate the control panel 130 to start the linear motor 120. The linear motor 120 drives the moving plate 300 forward until the positioning seat 350 moves out of the housing 200. Then, manually insert the connecting end of the shock absorber into the second positioning groove 361 and the shock absorber into the first positioning groove 360. Next, operate the control panel 130 to start the second electric telescopic rod 320. The second electric telescopic rod 320 drives the clamping block 330 to cooperate with the buffer pad 340 to clamp and fix the shock absorber. Then, start the linear motor 120 again. The linear motor 120 drives the moving plate 300 to move backward into the housing 200. In step 00, the first electric telescopic rod 220 is then activated. The first electric telescopic rod 220 drives the inflation head 230 to move downwards and connect with the shock absorber. The inflation head 230, together with the nitrogen filling tank 240 and the hose 250, inflates the shock absorber. After inflation, the linear motor 120 is activated. The linear motor 120 drives the moving plate 300 to move forward, and the second electric telescopic rod 320 is activated to retract. At the same time, the air pump 370 is activated. The air pump 370 transmits gas into the through hole 362 and guides it into the second positioning groove 361 through the through hole 362. This causes the shock absorber in the first positioning groove 360 ​​to move upwards under the influence of air pressure. Then, the shock absorber can be manually removed.
