Abstract
Description
Technical Field
[0001] This invention relates to the field of shock absorber assembly, and more specifically, to a liquid reservoir tightening machine. Background Technology
[0002] During the production and assembly of the shock absorber, the liquid storage tank needs to be firmly secured so that it can be used in conjunction with the tightening machine to complete the screw connection assembly of the bottom valve lug joint.
[0003] Currently, most existing liquid storage cylinder clamping devices use opposing clamping plates or simple compression clamping, which have problems such as poor clamping stability and uneven force distribution. This can easily cause the liquid storage cylinder to shift or shake during assembly, affecting the accuracy and efficiency of the joint screwing.
[0004] In addition, a tightening gun is required when tightening the bottom valve of the liquid storage tank. After attaching a tightening head that matches the bottom valve to the end of the tightening gun, the tightening gun is manually held and aligned with the bottom valve for tightening. The tightening gun is usually directly suspended on the balancer, without precise up-down and back-and-forth adjustment guides, resulting in poor operational stability, low alignment accuracy, and easy occurrence of tightening misalignment and substandard assembly quality. Summary of the Invention
[0005] The purpose of this invention is to provide a liquid storage cylinder tightening machine. After the liquid storage cylinder is tightened by the clamping mechanism, the bottom valve lug connector is screwed to the end of the liquid storage cylinder by adjusting the up-down and back-and-forth positions of the tightening gun. This machine has good stability and high efficiency.

[0022] Through the implementation of the above technical solution, the liquid storage cylinder tightening machine mainly includes a clamping mechanism 4 and a manual adjustment mechanism 1. In use, the liquid storage cylinder to be tightened is passed downwards through the space enclosed by multiple pressure plates 35, then downwards sequentially through a fixed ring, a first movable plate 14, and a third movable plate 29. The third movable plate 29 is then driven downwards by a screw assembly, causing the pressure sleeve 26 to move downwards. The inclined inner ring on the inner side of the pressure sleeve 26 presses against the outer inclined surface of the multiple pressure plates 35, squeezing the multiple pressure plates 35 inwards onto the outside of the liquid storage cylinder, thus achieving clamping of the liquid storage cylinder. By clamping the liquid storage cylinder, it is used in conjunction with a tightening machine located above the liquid storage cylinder to screw the bottom valve lug connector to the end of the liquid storage cylinder.

A support rod 39 is screwed onto the support plate 38, and a support disc 40 coaxial with the pressure sleeve 26 is installed at the upper end of the support rod 39. This arrangement provides support for the bottom of the liquid storage cylinder. In addition, by rotating the support rod 39, the external thread of the support rod 39 engages with the thread of the support plate 38 to adjust the height of the support disc 40, thereby adjusting the support height.
[0027] In this embodiment, the movable sleeve 37 has a threaded hole on its side, and a fastening screw is installed in the threaded hole. After the movable sleeve 37 is adjusted into place, the fastening screw is tightened from the side.

The front end of the smooth rods 23 is equipped with a gun seat 25 for mounting the tightening gun 3. In use, the tightening gun 3 is mounted on the gun seat 25. The height of the tightening gun 3 is adjusted by moving the vertical position of the gun seat 25 and under the vertical guidance of the guide posts 21. After adjustment, the downward gravity of the tightening gun 3 is balanced by the balancer 9. Then, the gun seat 25 is pulled according to the position of the lifting ring, so that the gun seat 25 drives the tightening gun 3 to move back and forth under the guidance of the smooth rods 23. Thus, the height and back and forth position of the tightening gun 3 can be adjusted according to the tightening needs, which is convenient for tightening the lifting ring at the upper end of the shock absorber connecting rod.
