Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber production and assembly, in particular to a manual spring assembly machine. Background Art

[0002] The spring is a key component of the shock absorber. During assembly, the spring must be compressed to fit within the shock absorber body. Currently, springs are typically installed with claws directly contacting the spring. This installation method can easily result in uneven force on both sides of the spring during installation, and the spring axis can deviate significantly from the shock absorber's main axis, creating safety risks during operation. Utility Model Content

[0003] The purpose of the utility model is to provide a manual spring assembly machine with simple structure and easy use in view of the defects and shortcomings of the existing technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a manual spring assembly machine, including a base, and its innovation lies in: a jack and a pair of columns are respectively arranged on the base, sliding sleeves are arranged on the columns, a movable plate is arranged between the sliding sleeves, the piston rod end of the jack is fixedly connected to the bottom of the movable plate, a lower positioning seat is arranged on the upper surface of the movable plate, a guide sleeve is arranged on the upper part of the column, a fixed plate is arranged between the guide sleeves, and an upper positioning seat is arranged at the bottom of the fixed plate.

[0005] Furthermore, a positioning hole is provided on the guide sleeve, and a plurality of pin holes are provided on the column at equal intervals in the longitudinal direction. When the positioning holes correspond to the pin holes, bolts are used for fixing.

[0006] Furthermore, the lower positioning seat and the upper positioning seat are located on the same central axis.

[0007] After adopting the above structure, the beneficial effects of the utility model are:

[0008] The utility model realizes the installation of the shock absorber through the pressure action of the manual hydraulic cylinder, and the compression stroke of the spring can be better adjusted through manual hydraulic control; when the spring assembly machine is in use, the force applied to the spring is horizontal pressing, rather than the claws on both sides directly pressing the spring. During the pressing process, the spring is evenly stressed as a whole, and the deviation between the axis of the spring and the main axis of the shock absorber is minimized. Therefore, it is easier to operate when installing the shock absorber without causing any damage to the spring itself, and the safety performance is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0014] See Figure 1 A manual spring assembly machine includes a base 1, on which a jack 2 and a pair of columns 3 are respectively provided, and a sliding sleeve 4 is provided on the column 3. The sliding sleeve 4 is fixedly connected to a movable plate 5, the piston rod end of the jack 2 is fixedly connected to the bottom of the movable plate 5, the upper surface of the movable plate 5 is installed with a lower positioning seat 6, the outer circle of the column 3 is assembled with a guide sleeve 7, the guide sleeve 7 is connected and fixed to a fixed plate 8, and the bottom of the fixed plate 8 is installed with an upper positioning seat 9. Specifically, the spring is put on the shock absorber, the upper positioning seat 9 and the lower positioning seat 6 are adjusted, the spring is put on the shock absorber and placed between the upper positioning seat 9 and the lower positioning seat 6, and then the jack 2 is started to push up the movable plate 5 and compress the spring, thereby achieving installation. In this method, the force applied to the spring is horizontal pressing, rather than the claws on both sides directly pressing the spring. During the pressing process, the spring is uniformly stressed as a whole, and the deviation between the axis of the spring and the main axis of the shock absorber is minimized. Therefore, it is easier to operate when disassembling and repairing the shock absorber without causing any damage to the spring itself, and the safety performance is guaranteed.

[0015] In this embodiment, the guide sleeve 7 is provided with positioning holes, while the column 3 is provided with a plurality of latch holes 31 equidistantly spaced longitudinally. When the positioning holes 31 correspond to the latch holes, they are secured using latches 10. The guide sleeve 7 slides up and down along the column 3 and is then secured via the positioning holes 31 and latch holes 10. The distance between the upper and lower positioning seats 9 and 6 is adjusted to accommodate shock absorbers of varying specifications.

[0016] In this embodiment, the lower positioning seat 6 and the upper positioning seat 9 are located on the same central axis, thereby ensuring that the shock absorber can be installed normally.

[0017] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
