Description

Technical Field

[0001] The utility model relates to the technical field of ball valve processing, in particular to a ball valve core processing and positioning tool. Background Art

[0002] A ball valve is a valve whose opening and closing member (the ball) is driven by a valve stem and rotates about its axis. It boasts a simple structure, excellent sealing performance, low fluid resistance, and easy operation. It is primarily used in pipelines to cut off, distribute, and change the flow direction of media. It requires only a 90-degree rotation and minimal torque to achieve a tight closure, making it widely used in industries such as petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, and steel.

[0003] During ball valve production, the machining accuracy of the valve core directly impacts the valve's sealing performance and service life. However, traditional ball valve core machining and positioning tooling often utilizes fixed fixtures. These fixtures suffer from drawbacks such as non-adjustable positioning points, poor adaptability, and the need to replace the entire fixture set for different valve core specifications. This not only increases production costs but also limits production flexibility. Furthermore, insufficient positioning accuracy can easily lead to accumulated machining errors, impacting the quality and performance of the final product. Utility Model Content

[0004] In response to the problems of inaccurate positioning, poor fixture versatility and low processing efficiency in the existing technology, the present invention proposes a ball valve core processing and positioning tool, aiming to provide a processing auxiliary device that can quickly adapt to valve cores of different specifications, high-precision positioning and easy operation.

[0005] A ball valve core processing and positioning tool of the present invention mainly includes the following components:

[0006] The main frame is a rectangular parallelepiped structure that provides a stable support base. It includes a lower base, an upper base, and support columns. The support columns are fixedly connected between the lower and upper bases to ensure the stability of the entire structure. The upper base is symmetrically provided with support seats to further reinforce the upper base and provide additional support points. Furthermore, a positioning mechanism is included within the main frame to precisely secure and position the ball valve.

[0007] Furthermore, the positioning mechanism includes a clamping unit, a threaded column, a threaded sleeve and a motor. The clamping unit is symmetrically arranged at the bottom of the upper base and is used to clamp and fix the ball valve. The threaded sleeve is mounted on the threaded column and can be moved up and down by rotating the threaded sleeve. Connecting ears are symmetrically provided on the threaded sleeve, and the connecting ears are fixedly connected to the threaded sleeve for connecting to the clamping unit. The bottom of the threaded column is fixedly connected to the output shaft of the motor. The rotation of the threaded column can be achieved by driving the motor, thereby controlling the up and down movement of the threaded sleeve. The motor is fixedly connected to the center position of the lower base to provide power for the entire positioning mechanism.

[0008] Furthermore, the clamping unit includes a first fixed rod, a fixed block, a clamping hoop body, a second fixed rod, a third fixed rod, a fourth fixed rod and a connecting block. These components together constitute a complex connecting rod mechanism for converting the movement of the threaded sleeve into the clamping action of the clamping hoop body. The first fixed rod is fixedly connected to the bottom of the upper base to provide support for the entire clamping unit. The first fixed rod is fixedly connected to the fixed block symmetrically on the left and right, and the fixed block is rotatably connected to the clamping hoop body through the connecting block, so that the clamping hoop body can rotate around the connecting block. The two ends of the second fixed rod are fixedly connected to the connecting block for connecting and supporting the third fixed rod. The third fixed rod is rotatably connected to the fourth fixed rod, and the fourth fixed rod is rotatably connected to the connecting ear. Through the transmission of the connecting rod mechanism, the movement of the threaded sleeve is converted into the clamping or loosening action of the clamping hoop body.

[0009] Furthermore, a clamping hoop opening is provided on the upper base at a position corresponding to the clamping hoop body, for accommodating the passage of the clamping hoop body, thereby ensuring that the clamping hoop body can smoothly clamp the ball valve without being obstructed.

[0010] Furthermore, the number of the clamping hoop openings corresponds to the number of the clamping hoop bodies, ensuring that each clamping hoop body has a corresponding clamping hoop opening, so as to clamp multiple ball valves or ball valves of different sizes at the same time, and then process the ball valve core.

[0011] Furthermore, dustproof nets are provided around the outside of the main frame to prevent dust and debris from entering the inside of the main frame, keeping the internal environment clean and tidy, and also helping to protect the internal mechanical components from damage.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] 1. The positioning mechanism, specifically the combination of a threaded column, threaded sleeve, and motor, enables precise control and positioning of the ball valve. The clamping unit utilizes a complex linkage design, with multiple fixing rods, fixing blocks, clamping hoops, and connecting blocks working together to securely clamp the ball valve. This design effectively prevents the ball valve from shaking or moving during processing, while simultaneously achieving both clamping and tightening the ball valve, simplifying the process and improving processing quality and efficiency.

[0014] 2. By flexibly adjusting the number and position of the clamping hoop and the clamping openings, the utility model can be applied to ball valves of different sizes and shapes, thereby facilitating the processing of subsequent ball valve cores. This design greatly enhances the versatility and adaptability of the tooling, reducing production costs and the frequency of tooling replacement.

[0015] The motor drives the threaded column and sleeve to automatically control the movement, simplifying the operation process. Workers only need to perform simple operations to complete the positioning and clamping of the ball valve, reducing labor intensity and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 5 This specific implementation case provides a specific implementation scheme for a ball valve core processing and positioning tool. The tool can accurately position and clamp the ball valve to facilitate subsequent ball valve core processing operations. The following is a detailed description of the tool:

[0025] The utility model provides a technical solution: a ball valve core processing and positioning tool, comprising a main frame 1 of a rectangular parallelepiped structure, which is composed of a lower base 11, an upper base 12, and support columns 13. The support columns 13 are firmly connected between the lower base 11 and the upper base 12, providing stable support for the entire tool.

[0026] A positioning mechanism 2 is provided inside the main frame 1 , comprising a clamping unit 21 , a threaded column 22 , a threaded sleeve 23 and a motor 24 .

[0027] Preferably, the clamping units are symmetrically arranged at the bottom of the upper base 12. Each clamping unit is composed of a first fixing rod 211, a fixing block 212, a clamping hoop body 213, a second fixing rod 214, a third fixing rod 215, a fourth fixing rod 216, and a connecting block 217. The first fixing rod 211 is fixedly connected to the bottom of the upper base 12 and is rotatably connected to the clamping hoop body 213 through the fixing block 212 and the connecting block 217. The second fixing rod 214 is connected to the connecting block 217 and is rotatably connected to the fourth fixing rod 216 through the third fixing rod 215. The fourth fixing rod 216 is rotatably connected to the connecting ear 231 on the threaded sleeve 23.

[0028] Preferably, the threaded sleeve 23 is mounted on the threaded post 22, and the two are threadedly engaged to achieve lifting motion. The bottom of the threaded post 22 is fixedly connected to the output shaft of the motor 24, which is fixedly connected to the center of the lower base 11. By activating the motor 24, the threaded post 22 is driven to rotate, which in turn drives the threaded sleeve 23 and the clamping unit 21 to move up and down, achieving height adjustment of the positioning mechanism 2.

[0029] Preferably, the motor 24 serves as a driving source to provide power for the entire positioning mechanism 2. By controlling the forward and reverse rotation and speed of the motor 24, the height and moving speed of the positioning mechanism 2 can be accurately adjusted.

[0030] Preferably, the clamping hoop 213 is arc-shaped, with a rubber layer on its inner surface to conform to the outer edge of the ball valve and provide sufficient clamping force. Clamping openings 14 are provided on the upper base 12 at positions corresponding to the clamping hoop 213, and the number of clamping openings 14 corresponds to the number of clamping hoop 213. This design ensures that when clamping the ball valve, the clamping hoop 213 can smoothly pass through the clamping openings 14 and tightly adhere to the outer edge of the ball valve.

[0031] Preferably, in order to protect the internal mechanisms and components of the tooling from dust and impurities, a dustproof net is provided around the outside of the main frame 1. The dustproof net can effectively prevent external dust and impurities from entering the tooling without affecting the normal operation and heat dissipation of the tooling.

[0032] Working principle: When using this tool, first place the ball valve between the clamping hoop mouth 14, provide basic support through the support seat 3 to relieve pressure, and start the motor 24 to drive the threaded column 22 to rotate. As the threaded sleeve 23 rises or falls, it drives the fourth fixed rod 216, thereby driving the third fixed rod 215, and then driving the second fixed rod 214, and then driving the connecting block 217. Finally, the clamping unit 21 and the clamping hoop body 213 will also move accordingly and fit on the outer edge surface of the ball valve. By adjusting the speed and direction of the motor 24, the clamping force and position of the clamping hoop body 213 can be precisely controlled. After clamping is completed, subsequent processing operations can be carried out.
