[0002] The existing front shock absorber air tightness testing device uses two cylinders to drive the left and right clamping blocks to hold and fix the front shock absorber. The front shock absorber is relatively long, and the clamping force on the left and right sides must be consistent to avoid the front shock absorber tilting. In addition, the cylinders must be large enough to ensure sufficient clamping force, and the overall length of the testing device is relatively long. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a front shock absorber air tightness testing device, which is designed to drive two clamping blocks to move left and right with a single power source, and to arrange the transmission structure using the front and rear space.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This front shock absorber airtightness testing device includes a machine base, a clamping mechanism, and a testing mechanism. The testing mechanism includes a plug, which is raised and lowered above the machine base. The clamping mechanism includes a clamping block that moves left and right. The machine base is provided with a mounting shaft and a guide plate. The mounting shaft extends vertically, and a swing arm is sleeved on the mounting shaft. The swing arm has a driving end and a driven end. One end of the driving arm is hinged to the driven end, and the other end of the driving arm is hinged to the driving block. A power source drives the driving block to move back and forth. The guide plate extends left and right. The clamping block is provided with a sliding groove and a driving groove. The sliding groove slides into the guide plate, and the driving groove allows the driving end to extend into it.

[0005] In this scheme, the power source drives the drive block to move back and forth, and the drive arm drives the swing arm to swing. The drive end abuts against the drive groove wall, causing the clamping block to move left and right along the guide plate.

[0006] Preferably, the plug has a taper.

[0007] In this design, the tapered design allows the plug to penetrate deep into the detection hole and reliably seal it.

[0008] Preferably, the cross-section of the drive end in the front-to-back direction is circular, and the cross-section of the slide groove is rectangular.

[0009] In this design, the circular drive end makes point contact with the rectangular groove, resulting in minimal wear.

[0010] Preferably, the clamping block includes a clamping head and a sliding seat, the clamping head and the sliding seat are detachably connected, the sliding seat is provided with the sliding groove and the driving groove, and the clamping head is provided with an arc-shaped groove for clamping.

[0011] In this solution, the clamp is replaced to change the arc groove to adapt to different specifications of front shock absorbers.

[0012] Preferably, the sliding seat is provided with a mounting protrusion and a first mounting hole, the mounting protrusion extends vertically, the first mounting hole is provided on both sides of the mounting protrusion, and the clamp is provided with a mounting groove corresponding to the mounting protrusion and a second mounting hole corresponding to the first mounting hole.

[0013] In this design, the mounting protrusion is embedded in the mounting groove so that the clamping block and the sliding seat are aligned in the front-to-back direction.

[0014] Preferably, the drive end has a clamping position and an open position, the drive end swings between the clamping position and the open position, and when the drive end is in the open position, the mounting shaft is located between the two drive ends in the left-right direction.

[0015] In this design, the drive end swings deep into the drive slot.

[0016] Preferably, the swing arm gradually narrows from the mounting shaft to the drive end.

[0017] In this design, the swing arm is narrowed to avoid contact with the drive slot wall during the swinging process.

[0018] Preferably, there are two guide plates, and the clamping block is located between the guide plates in the vertical direction.

[0019] In this design, the upper and lower limits of the two guide plates ensure stable guidance.

[0020] Preferably, the drive block is provided with a first hinge shaft and a second hinge shaft, the first hinge shaft and the second hinge shaft being respectively used for hinged connection of the drive arms on both sides.

[0021] In this design, the two drive arms will not be misaligned in the vertical direction, their structures are identical, and the left and right clamping forces are the same.

[0022] The beneficial effects of this utility model are as follows: the power source drives the drive block to move back and forth, which in turn drives the swing arm to swing. The drive end abuts against the drive groove wall, causing the clamping block to move left and right along the guide plate. The two drive arms on both sides will not be misaligned in the vertical direction, have the same structure, and have the same clamping force on both sides. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description
