Valve lock clip assembly equipment

Abstract

Valve collet component assembly equipment comprises a protection component, an operation box component, a pressing power component, a pressing limiting mechanism, an air inlet and outlet pressing switching servo mechanism, a pressing chuck, an air inlet and outlet overturning mechanism, a material feeding and conveying mechanism and a pressing supporting mechanism. The pressing chuck comprises a collet pressing cylinder and a collet pressing sleeve. When a valve collet is pressed, the collet pressing cylinder acts on the collet pressing sleeve, so that the collet pressing sleeve is used for pressing two collets which move upwards and are going to be completely disengaged from a spring seat due to the action of a valve ejector rod, meanwhile, the collet pressing cylinder enables a cylinder rod to make up-down reciprocating movement, the collet pressing sleeve is made to pat the collets, it is guaranteed that the collets can completely enter the inside of the spring seat, and the accuracy of valve collet pressing is guaranteed.

Description

technical field [0001] The invention belongs to the field of automobile engine assembly equipment, and in particular relates to an assembly equipment of an air door lock clip assembly. Background technique [0002] During the assembly process of the engine, it is very important to install the valve lock clip. It includes two semi-cylindrical lock clips of the same size and shape and a spring seat. The two lock clips form an approximate cylindrical structure and are set in the spring seat. When installing, it is necessary to install a matching press-fit on the valve lock clip press machine. Pressure head, use the pressure provided by the valve lock clip press machine to press-fit the valve lock clip to the valve ejector rod. Such as figure 1 As mentioned above, the existing pressure head is mainly composed of the outer pressure head 104, the inner pressure head 105, the spring 106 and the collar 107. Then, the inner pressure head 105, the spring seat, and the lock clip are...

AI Technical Summary

Problems solved by technology

like figure 1 As mentioned above, the existing pressure head is mainly composed of the outer pressure head 104, the inner pressure head 105, the spring 106 and the collar 107. Then, the inner pressure head 105, the spring seat, and the lock clip are mutually moving during the press-fitting process. Due to the unbalanced force in the press-fitting process, especially the force received by the valve ejector rod is transmitted through the valve lock clip, It often causes the valve ejector rod to shift slightly during the press-fitting process, which will cause the lock clip to not be pressed in place. It often happens that the lock clip will pop out halfway or jump out of the spring seat during the press-fitting process, making it necessary to reassemble, resulting in inefficiency. low
