Description

Technical Field

[0001] This patent relates to the field of shock absorber installation technology, specifically to shock absorber coil insertion equipment. Background Art

[0002] After the shock absorber is produced, it is necessary to set a spring coil on the outside of the shock absorber. Currently, mounting plates are set at both ends of the shock absorber. During assembly, a mounting plate is fixed to one end of the shock absorber, and then the spring is manually set on the outside of the shock absorber. Since the spring needs to be in a certain compression state after the shock absorber is fully assembled, it is necessary to manually compress the spring and then connect another mounting plate to the piston rod of the shock absorber. Manual pressing will increase labor intensity and inconvenience in operation. In addition, during subsequent use, the spring coil is easily stuck at the end of the outer tube of the shock absorber, causing the spring to be unable to be compressed. For this reason, we propose a shock absorber coil insertion device. Utility Model Content

[0020] The diameter and height of the lower circular plate 3 and the upper circular plate 6 are exactly the same;

[0021] The height of the spring 5 is greater than the height of the shock absorber body 2;

[0022] A retaining tube 12 is integrally formed at the middle of the bottom of the upper circular plate 6 . The inner diameter of the retaining tube 12 is larger than the outer diameter of the outer cylinder of the shock absorber body 2 , and the outer diameter of the retaining tube 12 is smaller than the inner diameter of the spring 5 .

[0023] After the T-hole 7 and the threaded groove 4 are connected by bolts, the piston rod of the shock absorber body 2 and the upper circular plate 6 can be connected as a whole. At this time, the retaining tube 12 can be located between the shock absorber body 2 and the spring 5, which can prevent the coil of the spring 5 from being stuck on the top of the outer tube of the shock absorber body 2 when the spring 5 is compressed.

[0024] Specifically, a circular groove 13 is provided in the middle of the top of the base 1 . The circular groove 13 is located directly below the connecting plate 10 . The diameter of the circular groove 13 matches the diameter of the lower circular plate 3 . The lower circular plate 3 is completely located in the circular groove 13 .

[0029] When the two push rods 11 are inserted into the two slots 15 , the upper circular plate 6 can correspond to the position directly above the shock absorber body 2 , which is convenient for assembly.
