An edge-holding device for combining mechanical parts

Abstract

The invention discloses a flange fixing device of a combined mechanical part. The flange fixing device of the combined mechanical part comprises a device body. A base is arranged at the bottom of thedevice body. A support pillar is arranged on the base. A support arm is arranged on the upper portion of the device body. A hydraulic cylinder is arranged at the top of the support arm. A hydraulic cylinder is arranged on the device body. A press block is arranged at the other end of the hydraulic cylinder. A pressure-joint die plate is arranged at the bottom of the press block. A position sensoris arranged on the lateral wall of the support arm. A slideway is arranged on the lateral wall of the support arm. A pressure die is arranged on the device body. A rotary die cavity is formed inside the pressure die. The flange fixing device of the combined mechanical part is simple in structure, convenient to use, good in flange fixing effect and not pone to deliberate falling. Through the rotarydie cavity, the flange fixing effect of a battery assembly is better, and the situation that the battery assembly falls off when flanges are not fixed in place is avoided. A time relay is used for carrying out pressure keeping control over the device body, flange fixing of the battery assembly is more compact, the work efficiency of flange fixing is high, and the flange fixing quality is high.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an edge-holding device for assembling mechanical parts. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing method, it can be divided into cutting processing and pressure processing. [0003] The traditional hemming method uses a punching machine to punch the hemming. The hemming method obviously has the disadvantages of cumbersome procedures and low production efficiency. Moreover, the pressure of the punching machine is relatively high, which is easy to cause damage to the mechanical parts and affect the quality of the mechanical parts. Moreover, the existing packaging After the edge machining is completed, the binding force of the edge pressing is often insufficient, and the mechanical parts fall off later, and the effect of the edge pressin...

[0003] The traditional hemming method uses a punching machine to punch the hemming. The hemming method obviously has the disadvantages of cumbersome procedures and low production efficiency. Moreover, the pressure of the punching machine is relatively high, which is easy to cause damage to the mechanical parts and affect the quality of the mechanical parts. Moreover, the existing packaging After the edge machining is completed, the binding force of the edge pressing is often insufficient, and the mechanical parts fall off later, and the effect of the edge pressing is not very good. There may be some areas where the edge pressing is not complete and there are gaps, so it needs to be repaired. Improve
