[0001] This patent relates to the field of shock absorber installation technology, specifically to a shock absorber end cover press-in device. Background Art

[0002] After the shock absorber is produced, a spring coil needs to be set on the outside of the shock absorber. At present, end caps are set at both ends of the shock absorber. The two end caps are used to support the two ends of the spring. During the assembly process, one end cap is fixed to one end of the shock absorber, and then the other end cap is driven by a manual screw to be pressed onto the piston rod of the shock absorber;

[0003] In order to ensure the placement of the shock absorber, placement grooves are set on the base and the pressure plate. When placing or removing the shock absorber, the pressure plate needs to be moved to a longer distance, which means that the screw needs to be rotated a longer number of times, which increases the labor intensity of the staff and makes the operation troublesome. For this reason, we propose a shock absorber end cover press-in device. Utility Model Content

[0019] Figure 1 In the embodiment, after the upper end cover 15 is connected to the top end of the piston rod of the shock absorber body 3 as a whole, the spring 16 will be in a compressed state.

[0020] The right end of the nut 11 is provided with a limiting mechanism.

[0021] Specifically, a slot is provided at the right end of the bottom wall of the rotating plate slot 6, a positioning hole is provided at the right side of the top of the rotating plate 8, a positioning rod 17 is provided in the positioning hole, and the bottom end of the positioning rod 17 is inserted into the slot.

[0022] The rotating plate 8 can be positioned by the positioning rod 17 so that the pressing plate 13 is located directly above the shock absorber body 3 .

[0023] Specifically, the limiting mechanism includes a vertical plate 18 and a connecting plate 20. The bottom end of the vertical plate 18 is fixedly mounted on the top right side of the rotating plate 8. The left side of the vertical plate 18 is provided with a wheel groove 19. The left side of the connecting plate 20 is fixedly mounted on the right end of the nut 11. The right side of the connecting plate 20 is provided with a mounting groove 21. A limiting wheel 22 is connected to the mounting groove 21 through a rotating shaft. The right end of the limiting wheel 22 is rollingly mounted in the wheel groove 19.

[0024] The traditional screw limiting mechanism is to limit the position by sliding a slider connected to the nut in the slide groove. The friction force is large, and the resistance is large when the staff manually turns the screw. If the right end of the limiting wheel 22 is rolled and installed in the wheel groove 19 for limiting, the sliding limit can be changed to a rolling limit, which greatly reduces the friction resistance and facilitates the operation of the personnel.

[0025] Specifically, magnets 23 are embedded on both left and right sides of the bottom of the pressing plate 13 .

[0026] The upper end cover 15 can be made of iron, and the bearing ring on the top of the upper end cover 15 can be adsorbed into the second placement groove 14 by the adsorption force of the magnet 23 .

[0027] Specifically, an annular groove 24 is provided on the top of the lower end cover 4 , and the bottom end of the spring 16 is inserted into the annular groove 24 .

[0028] The annular groove 24 is used to locate the assembly position of the spring 16 .

[0029] Specifically, a first through hole is provided at the left end of the plug block 5, a plug block slot is provided at the bottom of the upper end cover 15, the shape and size of the plug block 5 match the internal shape and size of the plug block slot, and second through holes are provided on the left and right walls of the plug block slot.

[0030] When the upper end cover 15 moves downward, the insert block groove is sleeved on the outside of the insert block 5 , and at this time, a long bolt can pass through the second through hole and the first through hole and be screwed with a nut to connect the piston rod of the shock absorber body 3 and the upper end cover 15 .

[0031] Working principle: The staff rotates the screw rod 10, and the nut 11 moves downward due to the limiting effect of the limiting mechanism, and the pressure plate 13 drives the upper end cover 15 to move downward. The insert block groove is set on the outside of the insert block 5. At this time, a long bolt can be passed through the second through hole and the first through hole to be screwed with the nut, thereby connecting the piston rod of the shock absorber body 3 and the upper end cover 15, and the spring 16 becomes compressed;

[0032] When removing the assembled shock absorber, rotate the screw 10 in the opposite direction to move the pressure plate 13 upward. It is only necessary to separate the pressure plate 13 from the upper end cover 15, then pull out the positioning rod 17, rotate the rotating plate 8 with the first bearing 7 as the axis, and rotate the pressure plate 13 to the top of the shock absorber to separate from the shock absorber. The shock absorber can then be taken out of the first placement groove 2, which facilitates the placement and removal of the shock absorber body 3. There is no need to rotate the screw 10 over a large range, which reduces the operating intensity and is more practical.
