Technical Field

[0001] This utility model relates to a shock absorber indicator mechanism, and in particular to a positioning and locking device for a shock absorber indicator mechanism. Background Technology

[0002] Shock absorbers are divided into front and rear types, with the front shock absorber being much longer than the rear shock absorber. The upper positioning mechanism is raised and lowered to accommodate the length changes of the front and rear shock absorbers. However, the vibration during shock absorber testing is relatively large, and the stability of the upper positioning mechanism is insufficient. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a positioning and locking device for a shock absorber indicator, wherein the locking power source drives the locking block to clamp the guide column between the movable part and the fixed part, thereby completing the locking.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This shock absorber indicator positioning and locking device includes a machine base, an upper positioning mechanism, and a lower positioning mechanism. The lower positioning mechanism is vertically oriented. The upper positioning mechanism has a front shock absorber positioning position and a rear shock absorber positioning position. The upper positioning mechanism moves vertically between the front shock absorber positioning position and the rear shock absorber positioning position. The machine base is provided with a guide post. The upper positioning mechanism includes an upper plate extending in the left-right direction. The upper plate has a guide hole for the guide post to pass through. The upper plate has a locking gap communicating with the guide hole. The locking gap divides the upper plate into a fixed part and a movable part. The movable part is equipped with a locking block that moves back and forth. The fixed part is provided with a locking power source. The output shaft of the locking power source passes through the fixed part, the locking gap, the movable part, and is connected to the locking block.

[0005] In this scheme, the locking gap divider plate forms a movable part and a fixed part. When the upper positioning mechanism is raised and lowered, the locking power source drives the locking block to loosen the guide post by moving the movable part and the fixed part. During the test, the locking power source drives the locking block to clamp the guide post by moving the movable part and the fixed part.

[0006] Preferably, the upper plate is provided with a deformation hole that communicates with the locking gap.

[0007] In this design, the deformation hole forms a large gap to allow the moving part to deform relative to the fixed part.

[0008] Preferably, the locking gap is connected to the front side of the upper plate, and the locking power source is located on the back side of the upper plate.

[0009] In this design, the locking gap is connected to the front of the upper plate, forming an independent and highly flexible movable part.

[0010] Preferably, a clamping power source is provided below the upper plate, the clamping power source drives a set of V-shaped clamps to open and close, the clamping power source and the locking power source are hydraulic cylinders, and the clamping power source and the locking power source are equipped with flow dividers.

[0011] In this design, the diversion valve ensures the synchronization of clamping and locking.

[0012] Preferably, the upper plate is detachably connected to a rear reduction coupling seat, the rear reduction coupling seat is provided with a pin hole for the pin shaft to pass through, and the rear reduction coupling seat is located between the V-shaped clamps.

[0013] In this scheme, the disassembled and reassembled connecting seat is used to adapt to the change in the length of the shock absorber to be tested.

[0014] Preferably, the lower positioning mechanism includes a lower connecting seat, which has a pin hole through which the pin shaft passes.

[0015] In this scheme, the pin passes through the pin hole on one side, the hole at the lower end of the shock absorber, and the pin hole on the other side in sequence to complete the positioning of the lower end of the shock absorber.

[0016] Preferably, the lower connecting seat includes a base plate and a side plate, the side plate is adjustable to move back and forth on the base plate, and the side plate is provided with the pin hole.

[0017] In this design, the side plates are moved forward and backward to adjust the rear shock absorber so that it remains vertical between the upper and lower positioning mechanisms.

[0018] Preferably, the lower positioning mechanism includes a guide rod, which is connected to the lower connecting seat, and the machine base is provided with a bushing that slides with the guide rod.

[0019] In this design, the guide rod and bushing work together to guide the lifting and lowering of the lower positioning mechanism.

[0020] Preferably, the lower connecting seat is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the turntable, with the hinge point being eccentrically set.

[0021] In this design, the turntable raises and lowers the lower connecting seat via a connecting rod.

[0022] Preferably, the turntable is provided with a slider for radial movement adjustment, and the slider is hinged to the connecting rod.

[0023] In this design, the radially movable adjusting slider can adjust the lifting stroke of the lower connecting seat.

[0024] The beneficial effects of this utility model are as follows: the upper plate, which divides the locking gap, forms a movable part and a fixed part; when the upper positioning mechanism rises and falls, the locking power source drives the locking block to loosen the guide post by moving the movable part and the fixed part; during testing, the locking power source drives the locking block to clamp the guide post by moving the movable part and the fixed part. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description
