However, after assembly, the entire assembly is in a vertical state, which cannot meet the inclined installation requirements of the McPherson shock absorber. The installation angle of the shock absorber is different from that of the complete vehicle, and the performance characteristics of the McPherson shock absorber cannot be effectively and accurately tested.

[0011] As a further technical solution, the lower connecting tooling is an "L"-shaped structure, with a lower fixing hole for connecting the rotating block at its bottom, and a side fixing hole for connecting the steering knuckle bracket of the shock absorber.
[0012] As a further technical solution, a notch is provided on the rotating block for embedding the protrusion, and the rotating block and the protrusion are rotatably connected via a pin shaft.

DETAILED DESCRIPTION
[0024] The following is a detailed introduction to the present invention with reference to the accompanying drawings:
[0025] Example: As shown in the attached Figures 2 to 5 As shown, this installation angle adjustable fixture structure for shock absorber testing includes an upper connecting fixture 1, a tapered groove 11, an upper fixing hole 12, a shock absorber 2, a steering knuckle bracket 21, an angle adjustment fixture 3, a rotating block 31, a notch 311, an indicator rod 312, a pointer groove 313, a slider 32, a protrusion 321, a locking hole 322, a positioning plate 33, an arcuate groove 331, a rotation angle scale line 332, a sliding guide rail 34, a test bench 4, a lower connecting fixture 5, a lower fixing hole 51 and a side fixing hole 52.
[0026] Reference Attachment Figure 2 、 5 The upper connecting fixture 1 has a tapered groove 11 at its bottom that matches the top structure of the shock absorber 2 for positioning. Three upper fixing holes 12 are evenly spaced on the upper connecting fixture 1. These holes are bolted to the top of the shock absorber 2, allowing the upper connecting fixture 1 to connect to external testing equipment.
[0027] like Figure 2 、 4 As shown, the lower connecting tool 5 is an "L"-shaped structure, with a lower fixing hole 51 at the bottom, which is threadedly connected to the top of the rotating block 31. Two side fixing holes 52 are set on the side of the lower connecting tool 5, which can be connected to the steering knuckle bracket 21 of the shock absorber 2 by bolts, so that one end of the lower connecting tool 5 is fixed to the bottom of the shock absorber 2, and the other end is fixedly connected to the rotating block 31.
[0028] Reference Attachment Figure 3The angle adjustment fixture 3 includes a sliding rail 34, a slider 32 slidably connected to the sliding rail 34, and a positioning plate 33 fixed to the slider 32. The slider 32 is provided with a protrusion 321. Accordingly, a notch 311 is provided on the rotating block 31. The protrusion 321 is aligned and inserted into the notch 311, so that the rotating block 31 and the protrusion 321 (slider 32) are rotatably connected via a pin. Furthermore, an indicator rod 312 is provided at the center of the rotating block 31. An arcuate groove 331 is provided on the positioning plate 33. The indicator rod 312 passes through the arcuate groove 331. The rotation angle scale 332 provided on the surface of the positioning plate 33 indicates the rotation angle of the rotating block 31 and the shock absorber 2.
[0029] Preferably, a pointer slot 313 is formed at the end of the indicator rod 312 extending from the arcuate slot 331. This slot 313 can align with the rotation angle scale 332 to indicate the real-time rotation angle. The indicator rod 312 is a screw. Once the angle adjustment tool 3 is rotated to the desired test angle, a nut is inserted into the indicator rod 312 and tightened, thereby locking the rotation angle of the rotating block 31 relative to the positioning plate 33.
[0030] Furthermore, a test bench 4 is installed at the bottom of the sliding rail 34, capable of driving the sliding rail 34 up and down. Locking holes 322 are provided on both sides of the slider 32. Bolts are installed in the locking holes 322 to secure the slider 32 to the sliding rail 34. During the shock absorber test, the entire fixture can move up and down smoothly, simulating the movement of the shock absorber on an actual vehicle.
[0031] The working process of this utility model:
[0032] Before the test, according to the input of the shock absorber installation angle by the OEM, the shock absorber installation angle is set on the test bench 4. Figure 2 The installation shown simulates the shock absorber installation state of a complete vehicle. The installation angle can be adjusted using the rotating block 31 in the fixture structure. During adjustment, the rotation angle scale 332 accurately reads the rotation angle of the shock absorber 2. After the angle adjustment is completed, the indicator rod 312 and the positioning plate 33 are tightened with nuts. Next, the slider 32 is slid on the sliding guide 34 to simulate the longitudinal projection length of the shock absorber 2, allowing the shock absorber 2 to be installed on the test bench 4. Finally, the slider 32 is secured to the sliding guide 34 with bolts using the locking hole 322 provided in the slider 32. This ensures that the entire fixture can move smoothly up and down during the shock absorber 2 test, thereby simulating the movement of the shock absorber on an actual vehicle.
[0033] The utility model can quickly and accurately test the performance characteristics of the shock absorber, and is currently applied in the after-sales quality assessment of the shock absorber, thereby shortening the shock absorber development cycle and reducing development costs.
[0034] It is understandable that for those skilled in the art, any equivalent replacement or change of the technical solution and the concept of the utility model should fall within the scope of protection of the claims attached to the utility model.
