Description

Technical fields:

[0001] This utility model belongs to the field of spring vibration damper production, and in particular relates to special tooling for spring vibration damper assembly. Background technology:

[0002] A spring shock absorber is a vibration control device that is highly responsive to displacement. It is mainly used to suppress the oscillations caused by the rebound after the spring absorbs the shock and to mitigate impacts from the road surface. A spring shock absorber mainly consists of components such as the damper assembly, the spring, the upper spring support, and the lower spring support.

[0003] In the actual assembly process of spring shock absorbers, a large press is usually used to compress the spring so that the end of the shock absorber assembly passes through the spring support hole. Then, the limiting ring, locking washer, and other accessories are assembled onto the shock absorber assembly. Although this method can successfully complete the assembly of spring shock absorbers, the operation of large presses is relatively cumbersome and slow, time-consuming and labor-intensive, resulting in low assembly efficiency. Furthermore, large presses are not equipped with dedicated protective components, and if a spring bounces during compression, it can easily cause injury to personnel on site, posing a safety hazard. Summary of the Invention:

[0004] The purpose of this utility model is to provide a special tooling for assembling spring shock absorbers, and to overcome the shortcomings of the prior art. It effectively solves the existing problems of low assembly efficiency and safety hazards of spring shock absorbers.

[0005] The present invention relates to a special tooling for assembling a spring damper, comprising a pair of channel steels arranged opposite each other, a top plate and a clamping plate vertically installed at both ends of the channel steels respectively, a circular slot being provided on the clamping plate, and circular holes being provided at the two apex corners of the top plate and the clamping plate, into which a circular rod is inserted, and end liner plates being installed on the bottom walls at both ends of the channel steels.

[0006] Furthermore, an arc-shaped support plate is vertically installed on the inner side wall of the top plate, and the arc-shaped support plate is coaxial with the circular bayonet.

[0007] Furthermore, a pair of through holes are provided on the end liner.

[0008] Furthermore, reinforcing ribs are installed between the top plate and the channel steel, and between the clamping plate and the channel steel.

[0009] Furthermore, a middle liner plate is installed in the middle section of the channel steel.

[0010] Furthermore, the spacing between the pair of channel steels arranged opposite each other is smaller than the outer diameter of the spring.

[0011] The beneficial effects of this utility model are as follows: By matching the spring, shock absorber assembly and other components in a special tooling, and using a relatively small spiral jack to press the spring, the limiting ring, stop washer and other accessories can be quickly assembled on the shock absorber assembly, thereby improving the assembly efficiency of the spring shock absorber and saving time and effort; secondly, the protective column formed by the two round rods protects the safety of on-site personnel in the event of an accidental spring bounce.

Detailed implementation method:

[0017] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0018] like Figures 1 to 4 As shown, a special tooling for assembling a spring damper includes a pair of channel steels 1 arranged opposite each other. A top plate 2 and a clamping plate 3 are vertically installed at both ends of the channel steels 1, respectively. A circular slot 4 is provided on the clamping plate 3. Circular holes 5 are provided at the two apex corners of the top plate 2 and the clamping plate 3. A round rod 6 is inserted into the circular holes 5. End liner plates 7 are installed on the bottom walls of both ends of the channel steels 1. An arc-shaped support plate 8 is vertically installed on the inner side wall of the top plate 2. The arc-shaped support plate 8 is coaxial with the circular slot 4. A pair of through holes 9 are provided on the end liner plates 7. Reinforcing ribs 10 are installed between the top plate 2 and the channel steels 1, and between the clamping plate 3 and the channel steels 1. A middle liner plate 11 is installed in the middle section of the channel steels 1. The distance between the pair of channel steels 1 arranged opposite each other is less than the outer diameter of the spring 12.

[0019] Specifically, by matching the spring 12 and the shock absorber assembly 13 in a special tooling, and using a relatively small spiral jack 14 to press the spring 12, accessories such as the limit ring and the stop washer can be quickly assembled onto the shock absorber assembly.

[0020] In actual use, first, place the lower support of the spring 12 at the lower end, then pass the shock absorber assembly 13 through the lower support and the spring 12 in sequence. At this time, place the semi-assembled spring shock absorber on the groove formed by a pair of channel steels 1, and place the upper support of the spring in the circular slot 4 on the clamping plate 3. Then, place the screw jack 14 on the groove formed by the channel steel 1. At this time, the worker operates the screw jack 14 to extend the piston rod, so that it presses against the joint bearing in the shock absorber assembly 13. As the piston rod of the screw jack 14 continues to extend, the spring 12 is gradually compressed. The upper end of the shock absorber assembly 13 passes through the lower support of the spring. At this time, the worker assembles the limit ring, stop washer and other accessories on the shock absorber assembly from the outer end of the clamping plate 3, thus completing the assembly of the spring shock absorber.

[0021] During the assembly process described above, two round rods 6 can be inserted into the round holes 5, forming two protective pillars between the top plate 2 and the clamping plate 3. This prevents the spring 12 from bouncing outward when compressed, thus protecting the safety of on-site personnel. The screw jack 14 is placed in the arc-shaped support plate 8, which not only stabilizes it but also allows the piston rod of the screw jack 14 to be coaxial with the round clamping end 4, facilitating its quick alignment with the joint bearing end in the shock absorber assembly 13 and further improving assembly efficiency. The distance between a pair of channel steels 1 is smaller than the outer diameter of the spring 12, allowing the semi-assembled spring shock absorber to be placed stably on the groove formed by the channel steels 1. This further facilitates the quick alignment of the piston rod of the screw jack 14 with the joint bearing end in the shock absorber assembly 13, improving assembly efficiency. By placing bolts in the through holes 9, the special tooling can be installed on other workbenches for use, further increasing the application scenarios of the special tooling. The reinforcing ribs 10 and the middle liner plate 11 further strengthen the connection strength between the various components of the special tooling, extending its service life.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
