[0013] Preferably, a third fixing frame is provided at the rear end of the fourth support rod, and a fourth fixing frame is provided at the front end of the fourth support rod.

[0014] Working Principle: The dual-head motor drives the main rod to rotate, which in turn rotates the movable plate. The movable plate then rotates the connecting rod, causing the adjusting rod and movable block to swing on the fixed rod and support frame. The first pressure block fixed at the bottom of the support frame drives the movable rods on both sides to move up and down within the slide groove. This up-and-down movement of the first pressure block hammers down on the top of the shock absorber, performing a pressure resistance test on the shock absorber from above. The first pneumatic telescopic rod then drives the second pressure block to hammer down on the rear of the shock absorber, performing a pressure resistance test. Next, the dual-head motor starts, driving the second support rod and the first transmission wheel to rotate. The rotation of the first transmission wheel, via a connected first belt, drives the second transmission wheel to rotate. The rotation of the second transmission wheel drives the first support rod and the first pneumatic telescopic rod to rotate. The first pneumatic telescopic rod drives the second pressure block to continuously hammer the rear of the shock absorber. The shock absorber is also subjected to compression to check if it bends forward when struck and compressed at the rear. The third pressure block is extended and contacts the front of the shock absorber via the second pneumatic telescopic rod. The second pneumatic telescopic rod then drives the third pressure block to extend and retract, striking the front of the shock absorber. Next, the dual-head motor is activated, causing the fifth transmission wheel connected to the right side of the first belt to rotate. This rotation drives the fourth support rod, which in turn drives the fourth transmission wheel. The fourth transmission wheel, in turn, drives the third transmission wheel via the second belt, which in turn drives the third support rod. The third support rod, in turn, drives the second pneumatic telescopic rod. Therefore, when the second pneumatic telescopic rod drives the third pressure block to strike the front of the shock absorber, it also rotates and compresses, resulting in a better test of the shock absorber's front compressive strength.

[0015] This invention provides a quality inspection device for the processing of automotive shock absorbers. It has the following beneficial effects:

[0016] 1. This invention uses a dual-head motor to drive the first pressure block, which in turn drives the movable rods on both sides to move up and down in the slide groove. The up and down movement of the first pressure block hammers and presses down on the top of the shock absorber at the bottom, thus performing a compressive quality test on the shock absorber from the top. This adds a compressive quality test from the top part of the shock absorber to the quality inspection after the automotive shock absorber leaves the factory.

[0017] 2. This invention uses a first pneumatic telescopic rod to drive the second pressure block to perform a hammering and compression quality test on the rear side of the shock absorber. A dual-head motor drives the first pneumatic telescopic rod to rotate the second pressure block, performing a rotational compression test while simultaneously testing the shock absorber's hammering and compression quality. This adds a compression quality test and a compression test to the rear side of the shock absorber during the quality inspection after the automotive shock absorber leaves the factory.

[0018] 3. In this invention, the second pneumatic telescopic rod drives the third pressure block to extend and strike the front of the shock absorber. The dual-head motor drives the second pneumatic telescopic rod to rotate the third pressure block to perform compression testing on the shock absorber. This improves the compression quality testing of the front of the shock absorber and enhances the compression testing effect.

[0019] 4. This invention uses a dual-head motor to simultaneously drive the first, second, and third pressure blocks to perform multi-directional quality checks on the shock absorber from the top, front, and rear sides to assess its compressive strength. Attached Figure Description
