Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, and in particular to a ball valve clamping fixture. Background Technology

[0002] Ball valves are a type of valve widely used in various industrial fields, with a unique structure and opening / closing method.

[0003] During the production of ball valves, their surfaces need to be machined to a smooth surface. Because of their spherical structure, they are difficult to fix. Existing conventional fixtures cannot hold them accurately, resulting in inaccurate or unpositioned positioning during machining. Consequently, the spherical surface cannot be cut, making it difficult to guarantee machining quality.

[0004] To address the problems in the existing technology, we propose a ball valve clamping fixture. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a ball valve clamping fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ball valve clamping fixture includes a ball valve and a clamping fixture; the clamping fixture includes a cylindrical column, the cylindrical column comprising a first half-cylinder and a second half-cylinder, the first half-cylinder and the second half-cylinder being arranged symmetrically, a threaded groove being formed on the inner side of the cylindrical column, a threaded rod being screwed into the inner side of the threaded groove, a conical block being provided at the inner end of the threaded rod, a slider being symmetrically attached to the upper side of the conical block, a damping rubber pad being attached to the outer side of the slider, and anti-slip textures being evenly distributed on the damping rubber pad.

[0008] Furthermore, the ball valve has an arc-shaped concave surface on its inner side and a circular opening on its side.

[0009] Furthermore, the end of the column is provided with an arc-shaped head, which matches the arc-shaped concave surface, and the outer diameter of the column is adapted to the inner diameter of the circular opening.

[0010] Furthermore, a hexagonal screw seat is fixedly installed on the outer end of the threaded rod, and a hexagonal groove is provided at the end of the hexagonal screw seat.

[0011] Furthermore, the first and second semi-cylinders are screwed together.

[0012] Furthermore, a transverse sliding groove is provided on the inner side of the column, and vertical sliding grooves are provided on both the upper and lower sides of the transverse sliding groove. The conical block is slidably installed on the inner side of the transverse sliding groove, and the slider is slidably installed on the inner side of the vertical sliding groove. A limit groove is provided on the side of the vertical sliding groove.

[0013] Furthermore, the bottom of the slider has an inclined surface that matches the inclined side of the conical block, and the side end of the conical block has a rotating groove, with the inner end of the threaded rod rotatably mounted inside the rotating groove.

[0014] Furthermore, an ear seat is fixedly installed on the side of the slider, the ear seat is slidably disposed inside the limiting groove, and a return spring is fixedly installed between the ear seat and the bottom of the limiting groove.

[0015] Compared with related technologies, the ball valve clamping fixture proposed in this utility model has the following beneficial effects:

[0016] In this utility model, a ball valve clamping fixture is provided. The end of a cylindrical column is inserted into the ball valve, aligning its arc-shaped head with the concave arc surface inside the ball valve. Rotating the threaded rod causes a conical block connected to its inner end to slide within a transverse groove, allowing the inclined side of the conical block to abut against the inclined surface of the slider. Driven by the conical block, the upper and lower sliders are pushed outwards into the vertical groove, ensuring the damping rubber pad on the slider firmly abuts against the concave arc surface inside the ball valve. This allows the ball valve to be stably clamped at the end of the cylindrical column with precise positioning, facilitating subsequent machining. The entire clamping fixture is detachable, allowing all parts to be disassembled for easy maintenance, repair, or replacement of components, making it highly practical. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Reference Figure 1-7 A ball valve clamping fixture includes a ball valve 1 and a clamping fixture 2. The clamping fixture 2 includes a cylindrical column 21, which includes a first half-cylinder 23 and a second half-cylinder 24. The first half-cylinder 23 and the second half-cylinder 24 are arranged symmetrically. A threaded groove 25 is provided on the inner side of the cylindrical column 21. A threaded rod 26 is screwed into the inner side of the threaded groove 25. A conical block 29 is provided at the inner end of the threaded rod 26. A slider 211 is symmetrically attached to the upper side of the conical block 29. A damping rubber pad 215 is attached to the outer side of the slider 211. Anti-slip textures are evenly distributed on the damping rubber pad 215. A transverse sliding groove 28 is provided on the inner side of the cylindrical column 21. Vertical sliding grooves 210 are provided on both the upper and lower sides of the transverse sliding groove 28. The conical block 29 is slidably installed inside the transverse sliding groove 28. The slider 211 is slidably installed inside the vertical sliding groove 210. A limit groove 212 is provided on the side of the vertical sliding groove 210.

[0027] With the above-mentioned configuration, the damping rubber pad 215 has evenly distributed anti-slip textures, resulting in a high surface roughness. Consequently, when the damping rubber pad 215 comes into contact with the arc-shaped concave surface 11 inside the ball valve 1, it can stably hold the ball valve 1 in place, facilitating subsequent cutting and finishing.

[0028] In this method, the inner side of the ball valve 1 is provided with an arc-shaped concave surface 11, the side of the ball valve 1 is provided with a circular opening 12, the end of the column 21 is provided with an arc-shaped head 22, the arc-shaped head 22 matches the arc-shaped concave surface 11, and the outer diameter of the column 21 is adapted to the inner diameter of the circular opening 12.

[0029] With the above-mentioned configuration, the arc-shaped head 22 matches the arc-shaped concave surface 11, so that when the end of the column cylinder 21 is inserted into the ball valve 1 through the circular port 12, the arc-shaped head 22 can fit against the side of the arc-shaped concave surface 11, thereby improving the fit between the column cylinder 21 and the inside of the ball valve 1.

[0030] In this method, a hexagonal seat 27 is fixedly installed on the outer end of the threaded rod 26, and a hexagonal groove is provided at the end of the hexagonal seat 27.

[0031] With the above-described configuration, the hexagonal socket 27 facilitates the rotation of the threaded rod 26 via the hexagonal socket 27, enabling subsequent adjustments. The hexagonal socket 27 is also easily rotated using a wrench. Furthermore, the hexagonal groove at the end of the hexagonal socket 27 allows the insertion of an L-shaped wrench into the groove to rotate and adjust the threaded rod 26. These features enable the invention to be adjusted using various auxiliary wrenches, facilitating daily use.

[0032] In this configuration, the first half-cylinder 23 and the second half-cylinder 24 are screwed together.

[0033] With the above-described configuration, the column 21 is composed of two completely symmetrical first half-column 23 and second half-column 24 screwed together. When the first half-column 23 and second half-column 24 are disassembled, the threaded groove 25, the transverse sliding groove 28, the vertical sliding groove 210 and the limiting groove 212 inside the column are all separated in pairs, and the internal components can be disassembled, which is beneficial for later maintenance or replacement of corresponding damaged parts and improves practicality.

[0034] In this method, the bottom of the slider 211 is provided with an inclined surface 216, which matches the inclined side of the conical block 29. The side end of the conical block 29 is provided with a rotating groove 217, and the inner end of the threaded rod 26 is rotatably installed inside the rotating groove 217.

[0035] With the above configuration, the inclined surface 216 matches the inclined side of the conical block 29, so that when the conical block 29 slides, it can drive the slider 211 to slide inside the vertical groove 210.

[0036] In this method, a lug 213 is fixedly installed on the side of the slider 211. The lug 213 is slidably disposed inside the limiting groove 212. A return spring 214 is fixedly installed between the lug 213 and the bottom of the limiting groove 212.

[0037] With the above-described configuration, the return spring 214 provides a pull force, which ensures that the inclined surface 216 of the slider 211 is always in contact with the inclined side of the cone block 29. As the cone block 29 slides left and right, the slider 211 slides up and down inside the vertical groove 210, so that the end of the slider 211 can not only extend out of the outside of the vertical groove 210, but also retract into the inside of the vertical groove 210 under the pull force of the return spring 214.

[0038] The working principle of the ball valve clamping fixture provided by this utility model is as follows:

[0039] In use, the end of the column 21 is inserted into the ball valve 1 through the circular port 12, and the arc-shaped head 22 of the column 21 is made to fit against the arc-shaped concave surface 11 of the ball valve 1. Then, the threaded rod 26 is rotated, which drives the conical block 29 to slide towards the ball valve 1. Then, under the abutment and pushing action of the inclined side of the conical block 29 and the inclined surface 216 of the inner side of the slider 211, the two sliders 211 on the upper and lower sides slide towards the outside of the vertical groove 210, so that the damping rubber pads 215 on the outer side of the two sliders 211 are stably abutted against the arc-shaped concave surface of the inner side of the ball valve 1, thus completing the work of stably abutting and clamping the ball valve 1 at the end of the column 21.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
