Description

Technical Field

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

[0002] A butterfly valve is a commonly used fluid control device. Its structure typically includes a valve body, valve seat, and valve core (butterfly plate). Precision machining of the valve core is a crucial step in ensuring the performance of a butterfly valve during manufacturing.

[0003] In existing butterfly valve manufacturing technology, the valve core is typically fixed to a stable platform during machining. This process is often achieved by securing the valve core's mounting port. However, since the butterfly valve's mounting port is usually located in the middle of the valve body, the sides of the valve lack effective support during machining. This instability in support can affect the accuracy and efficiency of valve core machining.

[0004] To address this issue, some devices incorporate additional support structures at the bottom of the butterfly valve. These supports are designed to provide a stable support platform for the sides or edges of the valve core, thereby improving stability during manufacturing. However, the height of these bottom support structures is typically fixed, which means that the support effect may not be ideal for butterfly valves of varying thicknesses, and the valve may still tilt or wobble during manufacturing. Utility Model Content

[0005] In view of this, the present invention provides a clamping device for butterfly valve processing. The present invention can effectively prevent butterfly valves of different sizes from tilting or shaking due to lack of support, and ensure the accuracy and efficiency of valve core processing.

[0006] To solve the above-mentioned technical problems, this utility model provides a clamping device for butterfly valve processing, including a bracket and an adjusting assembly. The adjusting assembly is located in the middle of the bracket, and includes a bidirectional screw rotatably connected to the middle of the bracket. Two symmetrically distributed sliders are threadedly connected to the middle of the bidirectional screw, and both sliders are slidably connected to the bracket. An arc-shaped piece is fixedly connected to the top of each slider. Support assemblies are provided on both sides of the bracket, and the support assemblies include support plates fixed to both sides of the bracket. A support is fixedly connected to the middle of the support plate on one side. The upper side of the support is an inner arc surface, and a limit rod is placed on the top of the support. A fixing plate is fixedly connected to the side of the support plate closest to the bracket. A slot is opened in the middle of each fixing plate, and the diameter of the limit rod is equal to the inner diameter of the slot. The controllable support method can effectively prevent butterfly valves of different sizes from tilting or shaking due to lack of support during processing, ensuring the accuracy and efficiency of valve core processing.

[0007] The adjustment assembly also includes guide rods fixedly connected to both sides of the middle of the bracket, with both sides of the slider slidably connected to the middle of the guide rods; thus ensuring that the slider moves smoothly and accurately.

[0008] Multiple anti-slip strips are fixedly connected to the outer arc surface of the arc-shaped plate; this provides friction and cushioning to protect the butterfly valve.

[0009] The inner arc surfaces of the arc-shaped pieces are all fixedly connected to reinforcing plates, and the inner arc surfaces of the arc-shaped pieces all face the side away from the center of the support; that is, to enhance the strength and stability of the arc-shaped pieces.

[0010] The center of each slot is threaded, and one end of the limit rod is threaded; this fixes the limit rod and prevents the butterfly valve from changing position.

[0011] The support assembly also includes a support plate fixedly connected to the bottom of the fixed plate; that is, to limit the swaying of the butterfly valve and ensure the normal operation of the arc plate.

[0012] The support plates are all lower than the top of the curved plate; that is, to avoid interfering with the operation of the curved plate and to ensure effective and limited support.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. By controlling the movement position of the arc-shaped plate, the height of the contact position between the arc-shaped plate and the bottom of the butterfly valve can be adjusted, thereby supporting butterfly valves of different diameters and thicknesses. This controllable support method can effectively prevent butterfly valves of different sizes from tilting or shaking due to lack of support during processing, ensuring the accuracy and efficiency of valve core processing.

[0015] 2. The bottom of the butterfly valve is raised evenly by the synchronously moving arc-shaped plate, which can apply force to the butterfly valve evenly and avoid deformation or damage to the butterfly valve caused by uneven force on one side. Attached Figure Description

[0024] 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 appendices 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.

[0025] like Figure 1-4 As shown: This embodiment provides a clamping device for butterfly valve processing, including a bracket 100 and an adjusting assembly 200. The adjusting assembly 200 is disposed in the middle of the bracket 100. The adjusting assembly 200 includes a bidirectional screw 201 rotatably connected to the middle of the bracket 100. A motor is fixedly connected to the middle of one side of the bracket 100. The output shaft of the motor is fixedly connected to the middle of one end of the bidirectional screw 201. Two symmetrically distributed sliders 202 are threadedly connected to the middle of the bidirectional screw 201. Both sliders 202 are slidably connected to the bracket 100. The top of the sliders 202... Each part is fixedly connected with an arc-shaped piece 203. Support components 300 are provided on both sides of the bracket 100. The support components 300 include support plates 301 fixed to both sides of the bracket 100. A support 101 is fixedly connected to the middle of the support plate 301 on one side. The upper side of the support 101 is an inner arc surface. A limit rod 302 is placed on the top of the support 101. A fixing plate 303 is fixedly connected to the side of the support plate 301 near the bracket 100. A slot 304 is opened in the middle of the fixing plate 303. The diameter of the limit rod 302 is equal to the inner diameter of the slot 304.

[0026] When it is necessary to clamp the butterfly valve core, place the butterfly valve between two fixed plates 303, then pick up the limit rod 302, and fix the middle part of the butterfly valve between the two fixed plates 303 through the slot 304 and the installation port of the butterfly valve. Then, by controlling the motor to drive the bidirectional screw 201 to rotate, the two sliders 202 are driven by the bidirectional screw 201 to move towards the middle of the bidirectional screw 201. At the same time, the arc plate 203 moves along with it until the arc plate 203 moves to the bottom of the butterfly valve. As the arc plate 203 continues to move, the top of the arc plate 203 begins to contact the bottom of the butterfly valve. As the arc plate 203 continues to move towards the middle of the bracket 100, the contact point between the top of the arc plate 203 and the butterfly valve continuously rises. The bottom of the butterfly valve is raised evenly by the synchronously moving arc plate 203, which can evenly apply force to the butterfly valve and avoid deformation or damage to the butterfly valve caused by uneven force on one side.

[0027] The butterfly valve is stably supported by multiple arc-shaped plates 203. At the same time, by controlling the movement position of the arc-shaped plates 203, the height of the contact position between the arc-shaped plates 203 and the bottom of the butterfly valve can be adjusted, so as to support butterfly valves of different diameters and thicknesses. This controllable support method can effectively avoid the tilting or shaking of butterfly valves of different sizes due to lack of support during the processing, and ensure the accuracy and efficiency of valve core processing.

[0028] Adjustment component 200, such as Figure 1 , 2 As shown in Figure 4,

[0029] The adjustment assembly 200 also includes guide rods 204 fixedly connected to both sides of the middle part of the bracket 100, and both sides of the slider 202 are slidably connected to the middle part of the guide rods 204;

[0030] The guide rod 204 can guide the movement of the slider 202 during movement, ensuring that the slider 202 can move smoothly and accurately along the guide rod 204 under the drive of the bidirectional screw 201.

[0031] Anti-slip strip 102 Figure 1 , 2 As shown in Figures 3 and 4,

[0032] Multiple anti-slip strips 102 are fixedly connected to the outer arc surface of the arc-shaped piece 203. The outer arc surface of the arc-shaped piece 203 faces the side close to the middle of the bracket 100. The outer arc surface of the arc-shaped piece 203 is the support surface.

[0033] The anti-slip strip 102 is made of rubber. When the arc-shaped plate 203 raises the bottom of the butterfly valve, the anti-slip strip 102 can directly contact the butterfly valve. The rubber anti-slip strip 102 has good elasticity and wear resistance, which can effectively absorb and disperse force during clamping, reduce wear on the bottom of the butterfly valve, and provide sufficient friction to prevent the butterfly valve from sliding. In addition, the rubber material of the anti-slip strip 102 also has a certain cushioning effect, which can absorb some of the impact force during processing and protect the butterfly valve from damage.

[0034] Reinforcing plate 103 Figure 1 , 2 As shown in Figure 3,

[0035] The inner arc surface of the arc-shaped piece 203 is fixedly connected to the reinforcing plate 103, and the inner arc surface of the arc-shaped piece 203 faces the side away from the center of the bracket 100.

[0036] The reinforcing plate 103 can support the bottom of the arc-shaped plate 203, thereby enhancing the strength and stability of the arc-shaped plate 203. This helps to improve the reliability of the arc-shaped plate 203 in the process of clamping and supporting the butterfly valve, ensuring that the butterfly valve remains stable during processing and that the processing accuracy will not decrease due to deformation or vibration of the arc-shaped plate 203.

[0037] Threads Figure 1 , 4 As shown,

[0038] The middle part of the slot 304 is threaded, and one end of the limiting rod 302 is threaded;

[0039] When the limiting rod 302 is inserted into the slot 304, it needs to be rotated to engage the thread of the limiting rod 302 with the slot 304, thereby fixing the limiting rod 302. This ensures that the limiting rod 302 can be firmly fixed in the slot 304, preventing the position of the butterfly valve from changing due to the movement of the limiting rod 302 during processing.

[0040] pallet 104 Figure 1 , 4 As shown,

[0041] The support assembly 300 also includes a support plate 104 fixedly connected to the bottom of the fixed plate 303, and the support plate 104 is aligned with the groove 304 in terms of vertical position.

[0042] When the butterfly valve core is fixed between the two fixing plates 303, the butterfly valve will wobble due to the lack of support on both sides. The bottom support plate 104 effectively limits the swaying amplitude of the butterfly valve, preventing it from rotating and swaying to an angle perpendicular to the arc-shaped plate 203. By limiting the swaying amplitude, the arc-shaped plate 203 can directly contact the bottom of the butterfly valve, ensuring its normal operation.

[0043] pallet 104 Figure 1 , 4 As shown,

[0044] The support plate 104 is lower than the top of the arc-shaped piece 203;

[0045] The fact that the support plate 104 is lower than the arc-shaped plate 203 ensures that the support plate 104 will not interfere with the arc-shaped plate 203 when the butterfly valve is clamped and processed. This arrangement allows the arc-shaped plate 203 to freely raise the bottom of the butterfly valve without being obstructed by the support plate 104, thereby ensuring that the arc-shaped plate 203 can effectively support and clamp the butterfly valve.

[0046] Working principle:

[0047] Place the butterfly valve between the two fixed plates, lift the limit rod, and fix the middle of the butterfly valve between the two fixed plates through the slot and the installation port of the butterfly valve. Control the motor to run, drive the bidirectional screw to rotate and drive the two sliders to move towards the middle of the bidirectional screw. At the same time, the arc-shaped plate moves with it until the arc-shaped plate moves to the bottom of the butterfly valve. The top of the arc-shaped plate begins to contact the bottom of the butterfly valve. As the arc-shaped plate continues to move towards the middle of the bracket, the contact point between the top and the butterfly valve continuously rises. The synchronously moving arc-shaped plate evenly raises the bottom of the butterfly valve, achieving uniform clamping of the butterfly valve.

[0048] 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.

[0049] 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.
