Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and in particular to an airtightness testing mechanism for motorcycle shock absorbers. Background Technology

[0002] The core principle of motorcycle shock absorber air tightness testing is to observe pressure changes or leakage phenomena after pressurization or vacuuming to determine whether there is air leakage in the shock absorber.

[0003] Currently, there are two methods: traditional water immersion and air pressure testing. The traditional water immersion method involves sealing one end of the shock absorber and immersing the other end in water after pressurizing it through an air inlet. Leakage is determined by visually observing whether air bubbles escape. This method relies on the operator's experience and requires immersing the shock absorber in a water tank, which may lead to water corrosion risks due to water quality or improper operation. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a motorcycle shock absorber air tightness testing mechanism that can accurately locate leaks in the motorcycle shock absorber without contact.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a motorcycle shock absorber air tightness testing mechanism, comprising:

[0006] Ultrasonic gas detection unit, used to detect the location of gas leaks in motorcycle shock absorbers;

[0007] The moving part, located inside the protective box, is used to move the ultrasonic gas detection part.

[0017] Furthermore, the clamping part includes symmetrical support rods disposed inside the protective box;

[0018] It also includes a first telescopic member rotatably mounted on a support rod, wherein the support rod is provided with a drive unit for driving the first telescopic member to rotate;

[0019] The clamping part also includes a clamping component disposed on the first telescopic member.

[0020] Furthermore, the clamping component includes a pivot shaft disposed on the first telescopic component, the pivot shaft being provided with a plurality of second telescopic components, and the second telescopic components being provided with clamping rods for clamping motorcycle shock absorbers.

[0026] This invention involves mounting a motorcycle shock absorber on a clamping unit. Two first telescopic members extend and retract to accommodate shock absorbers of different lengths. A second telescopic member and a clamping plate further clamp the shock absorber. A drive unit rotates the shock absorber to detect leaks at different locations. A sealing body then seals the opening of the shock absorber. A gas supply mechanism applies gas pressure to the shock absorber. A moving part drives an ultrasonic gas detection unit to detect leaks.

[0042] Please see Figure 1-6 This utility model discloses a motorcycle shock absorber air tightness testing mechanism, comprising:

[0043] The ultrasonic gas detection unit 1 is used to detect the location of gas leakage in the motorcycle shock absorber. The ultrasonic gas detection unit 1 is fixedly installed on the movable part 2.

[0044] The movable part 2 is fixedly installed on the top wall inside the protective box 4 to drive the ultrasonic gas detection part 1 to move. The protective box 4 is equipped with a sound insulation board to isolate external sound waves and avoid interference.

[0048] The control unit 7 is installed on the gas supply mechanism 6 and is used to control the operation of the ultrasonic gas detection unit 1, the moving unit 2, the clamping unit 5 and the gas supply mechanism 6.

[0049] In use, the clamping part 5 clamps the motorcycle shock absorber, and the air supply mechanism 6 seals the opening of the motorcycle shock absorber.
