Description

Technical Field

[0001] This utility model relates to the field of ball valve processing technology, specifically to a jig for ball valve processing. Background Technology

[0002] The working principle of a ball valve is to open and close the flow channel by rotating a ball. The machining accuracy of the ball directly affects the performance and service life of the ball valve. The ball clamping fixture is a key component in the ball valve manufacturing process.

[0003] Some existing ball valve machining fixtures use a two-sided, simultaneous fixing method. During the fixing process, the ball valve needs to be simply positioned so that the clamping devices on both sides can fix the ball valve.

[0004] However, because ball valves come in various diameters, this clamping method makes it difficult to accurately center the valve, leading to unstable clamping. Unstable clamping not only affects the manufacturing quality of the ball valve but can also pose safety hazards during operation.

[0005] Therefore, existing ball valve machining fixtures have certain limitations in adapting to the clamping requirements of ball valves of different diameters, and need further improvement and optimization. Utility Model Content

[0006] In view of this, the present invention provides a jig for ball valve processing. The present invention can ensure the stability of clamping different ball valves during the processing, and avoid processing quality problems and safety hazards caused by unstable clamping due to changes in the diameter of the ball valve.

[0007] To solve the above-mentioned technical problems, this utility model provides a jig for ball valve processing, including a bracket and an adjusting component. The bracket has multiple slots in the middle, and the adjusting component is set in the middle of one of the slots. The adjusting component includes a sliding groove in the middle of the slot, and two symmetrically distributed sliders are slidably connected in the middle of the sliding groove. The top of each slider is fixedly connected to a conical top block. The bracket has a clamping component for clamping the ball valve in the middle. The clamping component includes two symmetrically distributed electric push rods fixedly connected to the bracket. The telescopic ends of the electric push rods are fixedly connected to clamping blocks. The clamping component and the adjusting component are distributed vertically and vertically, which can ensure the stability of clamping different ball valves during the processing and avoid processing quality problems and operational safety hazards caused by unstable clamping due to changes in the diameter of the ball valve.

[0008] The adjustment assembly also includes fixed blocks that are fixedly connected to both ends of the slot on one side, and a bidirectional screw is rotatably connected to the middle of the fixed blocks; that is, the position of the slider can be adjusted to achieve precise control of the ball valve position.

[0009] The larger diameter end of each conical top block faces upwards, and both conical top blocks are hollow. The inner surfaces of both conical top blocks are curved. The hollow design and curved shape provide better guidance and support, making the ball valve stable and less prone to rolling during processing.

[0010] All clamping blocks are hollow cones; this increases the contact points with the ball valve, provides a more uniform clamping force, and reduces vibration and displacement during processing.

[0011] The side with the larger diameter of the clamping block is fixedly connected with a protective strip; this increases friction and prevents the ball valve from being damaged during clamping.

[0012] The clamping blocks are provided with multiple observation ports arranged in a ring along the central axis of the clamping blocks; this allows for convenient observation of the ball valve surface while reducing the weight of the clamping device.

[0013] The top of each slot is chamfered, and multiple anti-slip strips are fixedly connected to the top of each chamfer; this ensures the stability and safety of the ball valve during placement and processing.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. Once the midpoint of the ball valve rises to the same height as the clamping assembly, the two clamping blocks can be moved by controlling the synchronous extension and retraction of the electric push rod to clamp the ball valve. This clamping method ensures the stability of clamping different ball valves during processing, avoiding processing quality problems and operational safety hazards caused by unstable clamping due to changes in the diameter of the ball valve.

[0016] 2. Only one of the multiple slots is equipped with a clamping component and an adjusting component. The other slots can hold ball valves to be processed or ball valves that have been processed. With the addition of anti-slip strips and chamfers, these ball valves can be reliably placed, which can reduce the operator's switching time between different work stages and improve overall work efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] like Figure 1-4 As shown: This embodiment provides a jig for processing ball valves, including a bracket 100 and an adjusting component 200. The bracket 100 has multiple slots 101 in the middle, and the adjusting component 200 is provided in the middle of one of the slots 101. The adjusting component 200 includes a sliding groove 201 in the middle of the slot 101 on one side. Two symmetrically distributed sliders 202 are slidably connected in the middle of the sliding groove 201. A conical top block 203 is fixedly connected to the top of each slider 202. A clamping component 300 for clamping ball valves is provided in the middle of the bracket 100. The clamping component 300 includes two symmetrically distributed electric push rods 301 fixedly connected to the bracket 100. The telescopic ends of the electric push rods 301 are fixedly connected to clamping blocks 302. The clamping component 300 and the adjusting component 200 are distributed vertically and vertically.

[0027] When machining ball valves of different diameters, the ball valve is first placed on top of the slot 101 on one side. Then, by driving two sliders 202 to move, the two sliders 202 move along the groove 201 and gradually move closer together. Then, the conical top block 203 contacts the ball valve. At the same time, the ball valve is guided by the conical top block 203. As the gap between the two conical top blocks 203 decreases, the ball valve is squeezed and rises, eventually raising the midpoint of the ball valve to the same height as the clamping assembly 300. By controlling the gap between the two conical top blocks 203, the position of the ball valve can be effectively adjusted to ensure that the center of the ball valve is aligned with the clamping assembly 300. After the midpoint of the ball valve rises to the same height as the clamping assembly 300, by controlling the synchronous extension and retraction of the electric push rod 301, the two clamping blocks 302 can be moved to clamp the ball valve. This clamping method ensures the stability of the ball valve during processing, avoiding processing quality problems and operational safety hazards caused by unstable clamping due to changes in the diameter of the ball valve.

[0028] Adjustment component 200, such as Figure 2 , 3 As shown in Figure 4,

[0029] The adjustment assembly 200 also includes a fixing block 204 fixedly connected to both ends of the slot 101 on one side. A bidirectional screw 205 is rotatably connected to the middle of the fixing block 204. A motor is fixedly connected to one side of the fixing block 204 on one side, and the output shaft of the motor is fixedly connected to the middle of one end of the bidirectional screw 205.

[0030] When it is necessary to adjust the position of the conical top block 203, the motor is controlled to drive the bidirectional screw 205 to rotate, so that the two sliders 202 move in opposite directions along the slide groove 201, so that the sliders 202 move synchronously, thereby adjusting the position of the conical top block 203, and finally fixing the ball valve between the two conical top blocks 203 and in the middle of the bracket 100.

[0031] Conical top block 203 Figure 2 , 4 As shown,

[0032] The larger diameter end of the conical top block 203 is set upwards. The conical top blocks 203 are all hollow. The inner surfaces of the two conical top blocks 203 are both arc surfaces. The bottom diameter of the arc surface is smaller than the top diameter of the arc surface.

[0033] The hollow conical top block 203 allows for a better fit between the ball valve and the top block 203. Simultaneously, the varying diameter of the arc surface provides better guidance and support for the ball valve. When the ball valve is placed on the conical top block 203, its larger top diameter allows it to remain stable without rolling or moving. As the gap between the conical top blocks 203 gradually narrows, the ball valve is compressed and lifted under the guiding action.

[0034] Clamping block 302 Figure 1 , 2 As shown in Figure 3,

[0035] All clamping blocks 302 are hollow cones;

[0036] The hollow design allows the ball valve to have more contact points when clamped, thereby dispersing the clamping angle. Multiple contact points can provide a more uniform clamping force, reducing vibration and displacement of the ball valve during processing.

[0037] Protective strip 303, etc. Figure 2 As shown,

[0038] Protective strips 303 are fixedly connected to the side with the larger diameter of the clamping block 302, and the side with the larger diameter of the clamping block 302 faces the middle of the bracket 100.

[0039] The protective strip 303 is made of rubber, which not only increases the friction between the clamping component 300 and the ball valve, but also prevents excessive collision with the ball valve during clamping, thus avoiding damage to the ball valve.

[0040] Observation port 304 Figure 1 , 2 As shown in Figure 3,

[0041] Each clamping block 302 has multiple observation ports 304 arranged in a ring along the central axis of the clamping block 302.

[0042] When the ball valve is clamped and processed, the surface of the ball valve blocked by the clamping block 302 can be observed through the observation port 304, and the weight of the clamping device can be reduced.

[0043] Chamfer 102 Figure 1 , 2 As shown in Figure 3,

[0044] The top of each slot 101 is provided with a chamfer 102, and multiple anti-slip strips 103 are fixedly connected to the top of each chamfer 102;

[0045] The chamfer 102 allows for smoother placement and movement of the ball valve, preventing friction and potential damage to the ball valve at the top edge of the groove 101. The anti-slip strip 103 prevents the ball valve from sliding due to vibration or external forces during machining, ensuring its accurate positioning. The anti-slip strip 103 also provides additional friction, making the ball valve more securely positioned in the fixture.

[0046] Meanwhile, only one of the multiple slots 101 is equipped with a clamping component 300 and an adjusting component 200. The other slots 101 can hold ball valves to be processed or ball valves that have been processed. With the anti-slip strip 103 and chamfer 102, these ball valves can be reliably placed, which can reduce the operator's switching time between different work stages and improve the overall work efficiency.

[0047] Working principle:

[0048] First, the ball valve to be processed is placed in the slot of the bracket. By rotating the bidirectional screw, the position of the slider is adjusted so that the conical top block contacts the ball valve, thus achieving the initial positioning of the ball valve. The electric push rod pushes the clamping block to move towards the ball valve. The clamping block contacts the ball valve and applies clamping force to ensure the stability of the ball valve during processing.

[0049] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
