Description

Technical Field

[0001] The invention relates to the field of mechanical production, in particular to a tool fixture for assembling valves and valve brackets. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium.

[0003] For example, in a patent for a fixture for assembling valves and valve brackets (application number: CN211761362U), the shortcomings of the prior art in that the fixture structure is relatively complex and cannot be properly adjusted according to the model and size of the valve and bracket are solved. The fixture includes a base, a pillar welded to the base, and a valve clamp seat. A limiting groove and a guide groove are respectively provided on both sides of the upper surface of the base. The limiting groove and the upper sides of the guide groove are both provided with limiting clamps through guide blocks and the limiting blocks for sliding. A first screw with a rotating handle is inserted into the inside of the guide block. An adjustment frame seat is slidingly provided on the outer wall of the pillar, and an adjustment plate is provided in the middle of the adjustment frame seat. The utility model is not only simple in structure and easy to operate, but also convenient for adjusting the clamping degree of the fixture according to different valves and valve brackets.

[0004] For example, a tooling fixture for assembling valves and valve brackets (application number: CN204565979U) is disclosed, which includes a base, a stopper, and a pad. The base is composed of a horizontal bottom plate and a vertical plate vertically connected to the rear edge of the bottom plate. A horizontal platform extends forward from the top of the vertical plate, which is flush with the top of the vertical plate. Two threaded holes are opened on the right half of the vertical plate, and a horizontal spacer protrudes forward from the middle of the vertical plate. The horizontal spacer is concave in shape, with a rectangular notch in the center of its front end. Through holes for this are opened on the horizontal spacers on both sides of the rectangular notch. The stopper is L-shaped with a right-angle turn and is installed on the top of the base. The pad is rectangular and has an arch-shaped notch from its front edge to the rear, and is installed on the horizontal spacer. The use of this new type of fixture is simple to operate, convenient for accurately locating the relative positions of the valve and the bracket, and can effectively improve the installation speed.

[0005] Although the above two patents have made certain optimizations on the assembly of valve and bracket, the optimization effect is not ideal. Figure 2As shown in the assembly between the ball valve 1 and the bracket 2 and the driver 3, with the development of science and technology and the fact that some working environments are not suitable for people to enter and exit, more and more valves adopt pneumatic or electric unmanned execution control, and the drivers and valves are not necessarily designed to be straight up and down at the beginning. Some also adopt a staggered connection method. This requires the tooling to be able to adaptively make adaptive optimizations and be able to clamp and position valves, brackets and drivers of different sizes within a certain range. In order to facilitate assembly, it is sometimes necessary to position and clamp while inverting or deflecting to a certain angle for installation. Looking at the above two patents, neither of them has made any optimization in this regard, and the functions are relatively simple, which is not convenient for quickly making flexible adaptations according to the valve's clamping and positioning requirements. For this reason, we propose a tooling fixture for assembling valves and valve brackets. Summary of the Invention
