Description

Novel projection welding base Technical Field The utility model relates to a shock absorber, in particular to a novel projection welding base. Background The shock absorber of the connecting shaft type is required to be subjected to projection welding, the inner hole of the existing projection welding base cannot be matched with the connecting shaft (phi 26 mm), and particularly, projection welding cannot be carried out on the position of the bottom cover of the liquid storage barrel after the projection welding machine is arranged under the condition that the inner diameter and the outer diameter of the inner hole are slightly different. Disclosure of Invention In order to solve the technical problem that the inner hole cannot be matched with the connecting shaft, the utility model provides a novel projection welding base. The technical scheme of the utility model is as follows: the utility model provides a novel projection welding base, includes projection welding frock, projection welding frock upper portion is equipped with the upper groove, and projection welding frock lower part is equipped with the lower groove, is equipped with projection welding frock threaded connection department between upper groove and the lower groove, and projection welding frock lower part separates out splint through the center cutting, puts into the connecting axle in the projection welding frock, and projection welding frock breach department and splint pass through the bolt locking. The distance between the clamping plate and the notch of the projection welding tool is not more than 2mm. The top surface of the lower groove and the cutting line are on the same plane. Two sides of the lower groove are provided with two mounting holes, bolts are arranged on the mounting holes, and the number of the bolts is four. By using the technical scheme of the utility model, the structure is novel, the design is ingenious and simple, the problem that the inner hole of the existing projection welding tool is not matched and cannot be subjected to projection welding is solved, the process is simple to assemble, practical and efficient, and compared with other processes, the total cost is lower, and the application range is wide. Drawings Fig. 1, 2, 3, 4 are schematic structural views of the present utility model. Detailed Description The utility model is further described below with reference to the drawings and examples. Examples The novel projection welding base comprises a projection welding tool 1, wherein an upper groove is formed in the upper portion of the projection welding tool 1, a lower groove is formed in the lower portion of the projection welding tool 1, a projection welding tool threaded connection portion 2 is arranged between the upper groove and the lower groove, the inner wall of the projection welding tool threaded connection portion 2 is in a step shape, a clamping plate 5 is separated from the lower portion of the projection welding tool 1 through central cutting, a connecting shaft is placed in the projection welding tool 1, and a notch of the projection welding tool 1 and the clamping plate 5 are locked through a bolt 6. The distance between the clamping plate 5 and the two sides of the notch of the projection welding tool 1 is not more than 2 mm. The parting line separates the length of not more than 2mm from the contact two sides of the clamping plate 5, and the offset distance for the outer diameter of the connecting shaft to be increased is reserved, so that the clamping plate 5 is ensured not to protrude outwards as much as possible. The top surface of the lower groove and the cutting line are on the same plane. Two mounting holes are formed in two sides of the lower groove, bolts 6 are arranged on the mounting holes, and the number of the bolts 6 is four. When the fixture is used, the distance reserved between the clamping plate 5 and the two sides of the notch of the projection welding fixture 1 is used for matching a connecting shaft with larger outer diameter, the clamping plate 5 is prevented from protruding outwards, the attractiveness is affected, the universality of the fitting is high, the clamping plate 5 and the bolt 6 are used for locking, the fixture can be used universally under the condition that the outer diameter difference of the connecting shaft is not large, the installation is simple, the processing is convenient, and the cost is reduced. It should be understood that the foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the technical solutions of the present utility model, and it should be understood that the foregoing may be added, substituted, altered or modified within the spirit and principle of the present utility model by those skilled in the art, and all such added, substituted, altered or modified embodiments fall within the scope of the appended claims.
