Integral riveting tool for I-shaped automobile thrust rod body and riveting method of integral riveting tool

Abstract

The invention discloses an integral riveting tool for an I-shaped automobile thrust rod body and a riveting method of the integral riveting tool. The tool comprises an upper installing plate, a lower installing plate, a floating plate, upper riveting dies and lower riveting dies, wherein the upper riveting dies and the lower riveting dies are arranged on the upper installing plate and the lower installing plate correspondingly, and the two upper riveting dies and the two lower riveting dies are arranged. The tool further comprises two ball head sliding bases connected to the floating plate in a sliding manner, and two equal-height blocks arranged on the floating plate. Two sliding base power cylinders are further fixedly connected to the floating plate. Under driving of the two sliding base power cylinders, the two ball head sliding bases can move close to each other or away from each other relatively along the floating plate. The two ball head sliding bases can drive two ball heads to be connected to the two ends of a pipe in a sleeving manner. The floating plate is further provided with a vertical power cylinder, the lower riveting dies penetrate the floating plate, the floating plate can move back and forth in the vertical direction under the action of the vertical power cylinder, and hydraulic cylinders or air cylinders are adopted as the sliding base power cylinders and the vertical power cylinder. Through the integral riveting tool and the riveting method, the quality of the thrust rod body is guaranteed, and integral riveting can be finished at a time.

Description

technical field [0001] The invention relates to a riveting tool for a thrust rod body of an automobile and a riveting method thereof, in particular to a riveting tool and a riveting method for an entire body of an I-type automobile thrust rod. Background technique [0002] Automotive thrust rods are widely used in air suspension and multi-axle balance suspension. The annual market demand is more than 3 million sets. The assembly between the ball head and the pipe body of the thrust rod body mainly adopts welding or hot riveting process. However, welding is limited by welding materials and domestic welding technology levels, and problems such as weak welding and poor quality stability have occurred. Therefore, hot riveting technology is now widely used. [0003] When assembling the thrust rod body of type I automobiles, one ball head is riveted on one end of the pipe body first, and then the other ball head is riveted on the other end of the pipe body. Forming, it is difficu...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned patent documents also use multiple riveting to assemble the thrust rod body, so it is difficult to ensure that the distance between the central axes of the two ball heads meets the design requirements; in addition, the processing efficiency of riveting in this way is also very low
