Description

Technical Field

[0001] This utility model relates to the field of control valve assembly technology, specifically a positioning fixture for control valve assembly. Background Technology

[0002] Control valves play a crucial role in numerous industrial sectors such as petrochemicals, power generation, metallurgy, and pharmaceuticals. They are used to control parameters such as fluid flow, pressure, and direction, ensuring stable system operation and precise control. The assembly quality of control valves directly affects their performance and reliability. During assembly, each component, such as the valve core, valve seat, valve body, and actuator, must be precisely positioned and installed. Any installation deviation in any component can lead to problems such as control valve leakage, sluggish operation, and reduced control accuracy.

[0003] In current control valve assembly, the process often relies on manual operation and experience of workers. Workers determine the position of components by sight and simple measuring tools, which is not only inefficient but also makes it difficult to guarantee assembly consistency and accuracy. Differences in worker skill levels and habits can easily lead to inconsistent assembly quality. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning fixture for assembling control valves, which has the advantages of precise positioning of control valve parts and high positioning efficiency, and solves the problem of low assembly consistency and accuracy caused by current manual assembly of control valves.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for assembling a control valve, comprising a base plate, a driving mechanism on one side of the top of the base plate, and a support mechanism on the other side, the support mechanism comprising a support plate, a vertical plate on the side of the support plate facing the driving mechanism, a horizontal plate on the top of the vertical plate, one end of the horizontal plate extending above the driving mechanism, and a plurality of supports on the top of the end of the horizontal plate away from the vertical plate, wherein a clamping mechanism is commonly provided in the plurality of supports.

[0006] Preferably, the driving mechanism includes a telescopic motor, the output end of which is arranged facing upwards, and a driving column is provided at the top of the output end of the telescopic motor, and a circular push plate is provided at the top of the driving column.

[0007] Preferably, four supports are provided, each of which is U-shaped with the opening of the U facing upwards.

[0008] Preferably, the clamping mechanism includes four limiting posts, each of which is L-shaped and has a through hole at the bend.

[0009] Preferably, the top of the limiting post is provided with a protruding plate, the top of the protruding plate is provided with a positioning plate, the end of the positioning plate facing the center of the driving mechanism is provided with a positioning block, and the side of the positioning block facing the center of the driving mechanism is provided with an arc groove.

[0010] Preferably, a driving block is provided at one end of the limiting post facing the center of the driving mechanism, and an arc-shaped guide surface is provided at the bottom end of the driving block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a telescopic motor, drive column, push plate, limit column, through hole, drive block, and guide surface, uses a telescopic motor to drive the drive column to rise and fall. The push plate at the top of the drive column abuts against the guide surface at the bottom of the drive block, thereby driving the four limit columns to rotate around the corresponding through hole. This causes the tops of the four limit columns to rotate and open synchronously, allowing the control valve parts to be placed between the four limit columns. Lowering the push plate releases the support on the guide surface, and the four limit columns close synchronously, completing the positioning of the control valve parts. This mechanical method replaces manual labor for positioning the control valve parts, improving the uniformity and accuracy of control valve assembly.

[0013] 2. This utility model uses positioning plates, positioning blocks, and arc grooves. The four positioning plates rotate synchronously in opposite directions, and the arc grooves on the four positioning blocks fit the control valve accessories and correct their positions, thus completing the positioning of the control valve. By changing different positioning blocks, the positioning of control valves of different sizes can be achieved during assembly, making it quite practical. Attached Figure Description
