Automobile welded plate spring subjected to surface reinforcement treatment

The utility model discloses an automobile welding plate spring with a reinforced surface, which belongs to the technical field of automobile parts and comprises a plate spring body, inner clamping plates are uniformly inserted into the outer side of the plate spring body, and limiting grooves are formed in the outer sides of the inner clamping plates. Through a reinforcing mechanism composed of the inner clamping plates, the limiting grooves, the through grooves, the conical clamping blocks, the limiting blocks, the inner clamping plates, the mounting holes, the double-end threaded rods and the nuts, assembling is convenient, meanwhile, the conical clamping blocks are inserted into gaps between the plate springs, the contact area of the fixing mechanism and the outer side face of the plate spring body is increased, the stability in the using process is improved, and the service life of the plate spring is prolonged. The reinforcing effect is better, threaded holes are evenly formed in the double-end threaded
