Abstract
Description
Technical Field
[0001] This utility model relates to shock absorbers, and more particularly to a novel projection weld base. Background Technology
[0002] For shock absorbers that require projection welding of connecting shafts, the existing projection welding base inner hole cannot match the connecting shaft (φ26mm), especially when the inner and outer diameters of the two are not much different. After installing the projection welding machine, it is impossible to perform projection welding on the bottom cover of the liquid storage tank. Summary of the Invention
[0003] To solve the technical problem that the inner hole cannot match the connecting shaft, this utility model provides a novel projection welding base.
[0004] The technical solution of this utility model is as follows:
[0005] A novel projection welding base includes a projection welding fixture. The upper part of the projection welding fixture has an upper groove, and the lower part of the projection welding fixture has a lower groove. A threaded connection of the projection welding fixture is provided between the upper groove and the lower groove. A clamping plate is separated from the lower part of the projection welding fixture by a center cut. A connecting shaft is placed inside the projection welding fixture. The notch of the projection welding fixture and the clamping plate are locked together by bolts.
[0006] The clamping plate is no more than 2mm away from the notch of the projection welding fixture on both sides.
[0007] The top surface of the lower groove is on the same plane as the cutting line.
[0008] Two mounting holes are provided on both sides of the lower groove, and four bolts are provided in the mounting holes.
[0009] The technical solution of this utility model has a novel structure and a clever and simple design. It solves the problem that the inner hole of the existing projection welding tooling is mismatched and cannot be projection welded. The process is simple to assemble, practical and efficient. Compared with other processes, the total cost is lower and the scope of application is wide. Attached Figure Description
[0010] Figure 1 , 2 Figures 3 and 4 are structural schematic diagrams of this utility model. Detailed Implementation
[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example
[0012] like Figure 1 , 2A novel projection welding base shown in Figures 3 and 4 includes a projection welding fixture 1. The projection welding fixture 1 has an upper groove on its upper part and a lower groove on its lower part. A projection welding fixture threaded connection 2 is provided between the upper groove and the lower groove. The inner wall of the projection welding fixture threaded connection 2 is stepped. A clamping plate 5 is separated from the lower part of the projection welding fixture 1 by a central cut. A connecting shaft is placed inside the projection welding fixture 1. The notch of the projection welding fixture 1 and the clamping plate 5 are locked together by bolts 6.
[0013] The clamping plate 5 is no more than 2mm away from the notch of the projection welding fixture 1 on both sides. The dividing line separates the clamping plate 5 and cuts off a length of no more than 2mm from the two contacting sides, leaving a distance to offset the increase in the outer diameter of the connecting shaft, and to ensure that the clamping plate 5 does not bulge outward as much as possible.
[0014] The top surface of the lower groove is on the same plane as the cutting line.
[0015] Two mounting holes are provided on both sides of the lower groove, and four bolts 6 are provided in the mounting holes.
[0016] When in use, the distance between the notch on both sides of the clamping plate 5 and the projection welding fixture 1 is to match the connecting shaft with a larger outer diameter, and to prevent the clamping plate 5 from protruding outward, which would affect the appearance. This accessory has high versatility. It uses the clamping plate 5 and bolt 6 locking design, and can be used in cases where the outer diameter of the connecting shaft is not much different. It is simple to install, easy to process, and reduces costs.
[0017] It should be understood that the above description is only a preferred embodiment of the present utility model and is not sufficient to limit the technical solution of the present utility model. For those skilled in the art, within the spirit and principles of the present utility model, additions, subtractions, substitutions, transformations or improvements can be made based on the above description, and all such additions, subtractions, substitutions or improvements should fall within the protection scope of the appended claims of the present utility model.
