The bolt head of the locking bolt 2-5 is on the guide rail 2-2, and the locking bolt 2-5 positions the support frame 2-3.

[0028] Two support bearings 2-6 are installed on the upper part of the support frame 2-3. The axis of the support bearing 2-6 is parallel to the axis of the shock absorber 5. The two support bearings 2-6 support the shock absorber 5, and the shock absorber 5 is rotated and adjusted at an angle through the two support bearings 2-6.

[0029] The mobile clamping mechanism 3 is provided with a slider 3-1, a mobile bracket 3-2, a clamping fixture 3-3, a clamping bearing 3-4 and a clamping handle 3-5.

[0030] A T-slot is provided on one side of the base 1, and the bottom of the movable bracket 3-2 is connected to the slider 3-1, and the slider 3-1 slides in the T-slot. A clamping handle 3-5 is provided on the upper part of the clamping clamp 3-3, and the clamping handle 3-5 controls the lifting and lowering of the clamping clamp 3-3 through an elastic tensioning member, and the clamping handle 3-5 is pulled to control the clamping clamp 3-3 to be clamped on the top of the shock absorber 5.

[0031] Two clamping bearings 3 - 4 are provided at the lower part of the clamping fixture 3 - 3 . The axis of the clamping bearing 3 - 4 is parallel to the axis of the shock absorber 5 . The two clamping bearings 3 - 4 contact the shock absorber 5 . The two clamping bearings 3 - 4 assist in adjusting the angle of the shock absorber 5 .

[0032] The detection mechanism 4 is provided with a detection base 4-1 and a detection test rod 4-2, and the detection test rod 4-2 is inserted into the detection base 4-1 through the detection hole of the shock absorber 5.

[0033] Embodiment 2: Specific implementation process using the structural form of embodiment 1.

[0034] The base 1 can be processed by welding or casting. Its structure is provided with T-slots and reinforcing ribs. The T-slots are used for installing the movable bracket 3-2, and the reinforcing ribs ensure its rigidity. The function of the base 1 is to provide support and installation position for each component and ensure the stable placement of the inspection fixture.

[0035] The support 2-1 is installed by bolt fastening and pin positioning. When installing the guide rail 2-2, the parallelism and straightness of the rail need to be selected according to the measurement requirements.

[0036] The support frame 2-3 is an integral structure connected to the guide rail (2-2) by a linear bearing 2-4, and can be moved left and right according to the size of the side member. When it moves to the required position, the side of the movable support frame 2-3 is locked with a locking bolt 2-5 to ensure its stability. The support frame 2-3 uses a support bearing 2-6 where it contacts the shock absorber 5, which is convenient for the placement and rotation of the shock absorber 5.

[0039] The detection part is divided into two parts, one is the detection base 4-1, and the other is the detection test rod 4-2. The detection base 4-1 is installed on the base 1. When the tested part is installed in place, the detection test rod 4-2 is inserted into the corresponding position of the detection base 4-1 after passing through the installation slot of the shock absorber 5 to determine whether the component is qualified. The size of the detection test rod 4-2 has corresponding processing requirements according to the detection requirements, and there are position requirements for the installation position of the detection base 4-1.

[0040] Working principle:

[0041] The above-mentioned inspection tool is used to inspect the coaxiality and verticality of the shock absorber, including the following steps:

[0042] (1) Adjust the positions of the support frame 2-3 and the movable bracket 3-2 according to the size of the shock absorber 5 measured.

[0043] (2) Place the shock absorber 5 on the support frame 2-3 and fix it with a quick clamping device.

[0044] (3) Rotate the shock absorber 5 so that the detected port of the shock absorber 5 is in the correct position.

[0045] (4) Then insert the test rod 4-2 through the test hole into the installation base. After the shock absorber 5 is firmly installed, whether the test rod 4-2 can smoothly pass through the test hole and be inserted into the test base 4-1 can be determined to determine whether the coaxiality and verticality of the shock absorber 5 are qualified.
