Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for ball valve processing, and in particular to a clamping device for processing PVC ball valves. Background Technology

[0002] A clamping device for PVC ball valve processing is a specialized piece of equipment used to securely hold ball valve blanks or semi-finished products during the production and processing of PVC ball valves. Its main function is to ensure that the ball valve can be accurately positioned and kept stable during processing steps such as turning, drilling, and grinding, avoiding the impact of workpiece shaking or displacement on processing accuracy and product quality. This improves production efficiency and processing quality, and ensures that the key performance characteristics of PVC ball valves, such as sealing and durability, are effectively achieved. It is an indispensable auxiliary device in the PVC ball valve manufacturing process.

[0003] During the processing of ball valve bodies, clamping devices are required to hold them in place for stable and more precise processing. However, traditional clamping devices for ball valve body processing are expensive and not easy to promote on a large scale. Furthermore, once the ball valve body is fixed, it is not easy for the processing device to process it, which has certain limitations.

[0004] An existing patent (publication number: CN214444742U) discloses a clamping device for processing ball valve bodies, including a base, a pressure plate fixedly installed on the base, a pressure plate bolt threaded on the pressure plate, multiple upright plates fixedly installed in an arc shape on the base, positioning plates fixedly installed on the multiple upright plates, and multiple adjusting bolts threaded on the upright plates. A ball valve body is provided in the base and is positioned between the multiple adjusting bolts. A main cutter rod is inserted into the ball valve body. The bottom of the ball valve body is configured to cooperate with the pressure plate bolts. This utility model, by setting a pressure plate and setting pressure plate bolts on the pressure plate, can limit and fix the placed ball valve body to a certain extent. At the same time, by setting multiple adjusting bolts on multiple upright plates, the ball valve body can be further limited and fixed. Its fixing cost is low and the fixing effect is good. By inserting a main cutter rod into the fixed ball valve body, the ball valve body can be processed by controlling the main cutter rod.

[0005] To address the aforementioned issues, existing patents offer solutions. However, most existing clamping devices for PVC ball valve processing employ fixed clamping structures, which are difficult to adapt to the rapid clamping requirements of ball valves of different specifications. Changing clamps requires a significant amount of time for disassembly and adjustment, impacting production efficiency. Some devices use manual adjustment of clamping force, which is not only cumbersome to operate but also makes it difficult to ensure the uniformity and stability of clamping force, easily causing the ball valve to shift or deform during processing, affecting processing accuracy.

[0006] To address this, a clamping device for processing PVC ball valves is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a clamping device for processing PVC ball valves. This device solves the problems of existing clamping devices for processing PVC ball valves, which mostly use fixed clamping structures, making it difficult to adapt to the quick clamping requirements of ball valves of different specifications. Changing clamps requires a lot of time for disassembly and adjustment, affecting production efficiency. Some devices use manual adjustment of clamping force, which is not only cumbersome to operate, but also makes it difficult to ensure the uniformity and stability of clamping force, which can easily cause the ball valve to shift or deform during processing, affecting processing accuracy.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for processing PVC ball valves, including a fixed frame, a threaded rod provided on the inner wall of the fixed frame, an output structure provided on the left side of the fixed frame, a protective rod provided on the left side of the fixed frame, a slider threadedly connected to the surface of the threaded rod, a movable plate bolted to the top of the slider, a limit mechanism movably connected to the inner wall of the movable plate, and a ball valve structure clamped to the inner wall of the limit mechanism;

[0009] The limiting mechanism includes a mounting block, a connecting plate, and a limiting block. The limiting block is bolted to the connecting plate on the side closest to it, and the mounting block is bolted to the connecting plate on the side closest to it. The surface of the mounting block is movably connected to the inner wall of the movable plate.

[0010] Preferably, the inner wall of the limiting block is engaged with the surface of the ball valve structure, and a limiting groove is formed on the inner wall of the limiting block.

[0011] Preferably, a placement block is bolted to the side of the connecting plate away from the mounting block, and the ball valve structure is placed on top of the placement block.

[0012] Preferably, a positioning block is bolted to the side of the connecting plate away from the mounting block, and the inner wall of the positioning block is engaged with the surface of the ball valve structure.

[0013] Preferably, a knob is movably connected to the inner wall of the movable plate, and the surface of the knob is threadedly connected to the inner wall of the mounting block.

This application sets up a limiting mechanism, which fixes the position of the mounting block and the connecting plate during use, and fixes the position of the connecting plate and the limiting block. During use, the mounting block slides on the inner wall of the movable plate. When facing ball valve structures of different specifications and sizes, the appropriate limiting block can be easily replaced, and the fixture size can be flexibly adjusted to meet diverse processing needs. The movable connection between the movable plate and the mounting block allows the limiting mechanism to be quickly reset and put into use after replacement, which greatly shortens the tooling adjustment time and improves production efficiency.

[0019] 2. This application, by setting up a fixed frame and a threaded rod, allows the threaded rod to be set on the inner wall of the fixed frame during use. The threaded rod is threadedly connected to the slider. With the help of the servo motor drive of the output structure, the movable plate can achieve precise linear movement along the threaded rod, thereby quickly and stably clamping and fixing the PVC ball valve structure. This provides reliable positioning support for subsequent drilling and other processing steps, effectively avoiding displacement or shaking of the ball valve structure due to unstable clamping during processing, improving processing accuracy and yield. The protective rod can protect the output structure and prevent the fixed frame from being accidentally bumped during transportation. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A clamping device for processing PVC ball valves includes a fixed frame 1, a threaded rod 3 on the inner wall of the fixed frame 1, an output structure 4 on the left side of the fixed frame 1, a protective rod 5 on the left side of the fixed frame 1, a slider 6 threadedly connected to the surface of the threaded rod 3, a movable plate 7 bolted to the top of the slider 6, a limit mechanism 2 movably connected to the inner wall of the movable plate 7, and a ball valve structure 8 clamped to the inner wall of the limit mechanism 2.

[0029] The limiting mechanism 2 includes a mounting block 201, a connecting plate 202, and a limiting block 203. The side of the limiting block 203 closest to the connecting plate 202 is bolted to the connecting plate 202. The side of the mounting block 201 closest to the connecting plate 202 is bolted to the connecting plate 202. The surface of the mounting block 201 is movably connected to the inner wall of the movable plate 7.

[0030] In this embodiment: By setting a limiting mechanism 2, the mounting block 201 is fixed to the position of the connecting plate 202, and the connecting plate 202 is fixed to the position of the limiting block 203. During use, the mounting block 201 slides on the inner wall of the movable plate 7. When dealing with ball valve structures 8 of different specifications and sizes, the appropriate limiting block 203 can be easily replaced, flexibly adjusting the fixture size to meet diverse processing needs. The movable connection between the movable plate 7 and the mounting block 201 allows the limiting mechanism 2 to quickly reset and be put into use after replacement, significantly shortening tooling adjustment time and improving production efficiency. By setting up a fixed frame 1 and a threaded rod 3, the threaded rod 3 is set on the inner wall of the fixed frame 1 during use. The threaded rod 3 is threadedly connected to the slider 6. With the servo motor drive of the output structure 4, the movable plate 7 can achieve precise linear movement along the threaded rod 3, thereby quickly and stably clamping and fixing the PVC ball valve structure 8. This provides reliable positioning support for subsequent drilling and other processing steps, effectively avoiding displacement or shaking of the ball valve structure 8 due to unstable clamping during processing, improving processing accuracy and yield. The protective rod 5 can protect the output structure 4 to prevent accidental bumps to the fixed frame 1 during transportation.

[0031] Specifically, such as Figure 5 As shown, the inner wall of the limiting block 203 is engaged with the surface of the ball valve structure 8, and the inner wall of the limiting block 203 has a limiting groove 9.

[0032] Specifically, such as Figure 5 As shown, a placement block 10 is bolted to the side of the connecting plate 202 away from the mounting block 201, and the ball valve structure 8 is placed on top of the placement block 10.

[0033] Specifically, such as Figure 5 As shown, a positioning block 11 is bolted to the side of the connecting plate 202 away from the mounting block 201, and the inner wall of the positioning block 11 is engaged with the surface of the ball valve structure 8.

[0034] In this embodiment: the limiting groove 9 opened on the inner wall of the limiting block 203 facilitates the restriction of the position of the ball valve structure 8. Together with the support of the bottom of the ball valve by the placement block 10 and the precise positioning of the side of the ball valve structure 8 by the positioning block 11, a multi-dimensional limiting and fixing system is formed to ensure that the ball valve structure 8 remains stable during processing and avoids displacement or rotation caused by uneven force. The placement block 10 and the positioning block 11 not only share the clamping pressure and prevent the surface of the ball valve structure 8 from being damaged by excessive extrusion, but also help to quickly calibrate the position of the ball valve structure 8, further improving processing accuracy and efficiency.

[0035] Specifically, such as Figure 4 As shown, a knob 12 is movably connected to the inner wall of the movable plate 7, and the surface of the knob 12 is threadedly connected to the inner wall of the mounting block 201.

[0036] Specifically, such as Figure 4 , Figure 5 As shown, the inner wall of the movable plate 7 is provided with a mounting groove 13 that is used in conjunction with the mounting block 201, and the inner wall of the mounting block 201 is provided with a threaded groove 14 that is used in conjunction with the knob 12.

[0037] In this embodiment: By setting the knob 12, during use, the knob 12 can be rotated on the inner wall of the movable plate 7 and the mounting block 201, which facilitates the restriction of the position of the mounting block 201, and facilitates the subsequent stable positioning of the mounting block 201 and the limiting block 203. The mounting groove 13 opened on the inner wall of the movable plate 7 facilitates the mounting block 201 to be installed on the inner wall of the movable plate 7 through the mounting groove 13. The threaded groove 14 opened on the inner wall of the mounting block 201 facilitates the rotation of the knob 12 on the inner wall of the mounting block 201 through the threaded groove 14.

[0038] Specifically, such as Figure 3 As shown, a fixing plate 15 is bolted to the inner wall of the fixing frame 1, and the threaded rod 3 is rotatably connected to the fixing plate 15.

[0039] Specifically, such as Figure 2 , Figure 3As shown, the inner wall of the fixing frame 1 is provided with an adjustment groove 16 that is used in conjunction with the slider 6, and the inner wall of the slider 6 is provided with a threaded hole 17 that is used in conjunction with the threaded rod 3.

[0040] In this embodiment: the fixing plate 15 bolted to the inner wall of the fixing frame 1 provides a stable rotation fulcrum for the threaded rod 3, reduces the radial sway of the threaded rod 3 during transmission, and ensures the smoothness of the linear movement of the slider 6 along the threaded rod 3. The adjustment groove 16 opened in the inner wall of the fixing frame 1 provides precise sliding guidance for the slider 6, preventing it from deviating during movement. The threaded hole 17 opened in the inner wall of the slider 6 facilitates the rotation of the threaded rod 3 on the inner wall of the slider 6 through the threaded hole 17.

[0041] Working Principle: During the use of the fixed frame 1, the limiting mechanism 2 is set up. During use, the mounting block 201 is fixed to the position of the connecting plate 202, and the connecting plate 202 is fixed to the position of the limiting block 203. During use, the mounting block 201 slides on the inner wall of the movable plate 7. When dealing with ball valve structures 8 of different specifications and sizes, the appropriate limiting block 203 can be easily replaced, flexibly adjusting the fixture size to meet diverse processing needs. The movable connection between the movable plate 7 and the mounting block 201 allows the limiting mechanism 2 to quickly reset and be put into use after replacement, significantly shortening tooling adjustment time and improving efficiency. To improve production efficiency, a fixed frame 1 and a threaded rod 3 are installed. During use, the threaded rod 3 is set on the inner wall of the fixed frame 1 and is threadedly connected to the slider 6. With the servo motor drive of the output structure 4, the movable plate 7 can move precisely in a straight line along the threaded rod 3, thereby quickly and stably clamping and fixing the PVC ball valve structure 8. This provides reliable positioning support for subsequent drilling and other processing steps, effectively preventing displacement or shaking of the ball valve structure 8 due to unstable clamping during processing, thus improving processing accuracy and yield. The protective rod 5 can protect the output structure 4 to prevent accidental bumps to the fixed frame 1 during transportation.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
