Ball valve automatic assembly production line

Abstract

The invention relates to the technical field of ball valve assembly, in particularly to a ball valve automatic assembly production line. The ball valve automatic assembly production line comprises a conveying belt, a first sealing ring press-fitting device, a first sealing ring material taking device, a valve ball feeding device, a valve ball press-fitting device, a valve ball material taking device, a rotary disc device, a second sealing ring placing device, a pressing cap placing device and a pressing cap screwing device, in use, a first sealing ring assembly device press-fits a first sealing ring and then the first sealing ring material taking device remove and detect the first sealing ring, and then the first sealing ring is fed to the next process by the conveying belt; the valve ballis press-fitted by the valve ball feeding device and the valve ball press-fitting device, and the valve ball is fed to the next process by the conveying belt after the the valve ball is taken down and detected by the valve ball material taking device; and finally, a second sealing ring and a pressing cap are placed on the valve ball through the rotary disc device, the second sealing ring placingdevice and the pressing cap placing device, the valve body is internally screwed and formed with the pressing cap screwing device, then the first sealing ring, the valve ball, the second sealing ringand the pressing cap are assembled in a procedure divided mode, the previous assembly is detected before the next part is assembled, the error rate is greatly reduced, and the assembling quality and efficiency are effectively improved.

Description

technical field [0001] The invention relates to the technical field of ball valve assembly, in particular to an automatic ball valve assembly production line. Background technique [0002] Ball valve refers to the valve whose ball is driven by the valve stem and rotates around the axis of the ball valve, which can be used for fluid regulation and control. Ball valves are widely used in various fields because of their good wear resistance, good sealing performance, and light switch, and the market demand is large. [0003] The structure of the gas ball valve generally includes a valve body with a protruding cylindrical connection part on one side, a valve ball set in the valve body, and an in-line valve stem groove whose inner end extends into the valve body and is inserted into the valve ball. The valve stem, the outer end of the valve stem protrudes from the connecting part and is connected with the handle. Sealing rings are provided at both ends of the valve body, and a ...

AI Technical Summary

Problems solved by technology

At present, the assembly of ball valves is often done by manually installing the valve stem and valve ball, and when the pressure cap is rotated, due to the extrusion of the sealing ring, the rotation of the valve stem is easily caused, which in turn affects the installation of the valve ball, and the overall assembly efficiency is low

[0005] In view of the above-mentioned problem of low assembly efficiency by manually assembling the ball valve, in the prior art, there is a machine instead of manual assembly, but the existing ball valve assembly machine uses multiple devices on one piece of equipment for one-time assembly and molding through program control

Although it can improve the efficiency of assembly, because the action time between multiple devices is short, that is, after the assembly of the previous station is completed, the next process will be carried out immediately. In this way, if there is an error in the previous process, the entire process needs to be completed. It can only be tested as a whole, so the error rate of the ball valve after assembly is not easy to control, so the defect rate is high, which will cause waste of resources
