A ball valve automatic assembly production line

Abstract

The invention relates to the technical field of ball valve assembly, in particular to an automatic ball valve assembly production line, which includes a conveyor belt, a first sealing ring pressing device, a first sealing ring retrieving device, a valve ball feeding device, a valve ball pressing device, The valve ball retrieving device, the first turntable device, the second sealing ring placing device, the pressing cap placing device, and the pressing cap tightening device, when in use, the first sealing ring assembly device and the first sealing ring retrieving device sequentially assemble the first After the sealing ring is pressed and removed and tested, the conveyor belt is sent to the next process, and then the valve ball is pressed by the valve ball feeding device and the valve ball pressing device, and after the valve ball taking device is removed and tested, the conveyor belt Send it to the next process, and finally place the second sealing ring and the pressure cap on the valve ball through the turntable device, the second sealing ring placement device and the pressure cap placement device, and the pressure cap tightening device will screw the pressure cap into the valve body Forming, so that the first sealing ring, valve ball, second sealing ring and pressure cap can be assembled in different steps, and the previous assembly can be inspected before assembling the next part, which greatly reduces the error rate and effectively improves the assembly process. quality and efficiency.

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
