Description

Technical Field

[0001] This utility model belongs to the field of butterfly valve plate technology, specifically a butterfly valve plate processing and positioning device with a multi-angle adjustment mechanism. Background Technology

[0002] With the continuous improvement of industrial automation, butterfly valves, as fluid control devices widely used in petrochemical, water supply and drainage, and power industries, directly affect the reliability and stability of the entire system's operation due to their performance and quality. The valve plate, as the core component of the butterfly valve, plays a decisive role in the valve's sealing performance, fluid resistance, and other key indicators due to its machining precision.

[0003] In existing butterfly valve plate machining processes, fixed-angle positioning devices are typically used to position the valve plate. These traditional positioning devices mainly consist of a base, a simple clamping mechanism, and a unidirectional positioning component, which can only meet the positioning requirements of the valve plate at a fixed angle or a limited number of angles. When machining the valve plate at different angles, such as oblique drilling or multi-angle milling, these existing positioning devices cannot achieve flexible multi-angle adjustment. Operators must manually adjust the angle by disassembling and reassembling the valve plate and using auxiliary tools. This is not only cumbersome and inefficient, but also makes it difficult to guarantee the accuracy and consistency of angle adjustments, easily leading to large machining accuracy errors, increased scrap rates, and seriously affecting production efficiency and product quality.

[0004] Therefore, this utility model provides a butterfly valve plate processing and positioning device with a multi-angle adjustment mechanism. Utility Model Content

[0005] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, a butterfly valve plate processing and positioning device with a multi-angle adjustment mechanism is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A butterfly valve plate processing and positioning device with a multi-angle adjustment mechanism, comprising a base plate; a fixing ring is fixedly installed on the top of the base plate, a support mechanism is provided on the inner wall of the fixing ring, and a positioning component is provided on the inner wall of the fixing ring; an adjustment component is provided on the bottom of the inner wall of the fixing ring, and a lifting mechanism is provided on the inner wall of the fixing ring; a clamping component is provided on the bottom of the positioning block, and a connecting mechanism is provided on the bottom of the positioning block; the support mechanism includes an annular groove, rollers, and a rotating ring. The annular groove is opened in the middle of the inner wall of the fixing ring, and several sets of rollers are arranged in a ring rotational configuration within the annular groove on the inner wall of the fixing ring. The rotating ring is rotatably installed within the annular groove on the inner wall of the fixing ring, and the rollers are located on the surface of the rotating ring. The cooperation between the annular groove and the rollers enables the rotating ring to rotate more stably, while preventing excessive friction during rotation. The rotating ring enables the positioning block to have a rotational function, thereby providing the positioning block with a multi-angle adjustment function, facilitating processing by the user.

[0007] Preferably, the positioning component includes a positioning block and positioning pins. The positioning block is fixedly installed on the inner wall of the rotating ring, and several sets of positioning pins are provided. The several sets of positioning pins are fixedly installed on the top of the positioning block in a ring. In this scheme, the cooperation between the positioning block and the positioning pins can position the valve plate, so that the valve plate can be processed stably and the processing can be carried out normally.

[0008] Preferably, the adjusting assembly includes a forward and reverse screw and a motor. The forward and reverse screw is rotatably mounted on the bottom of the inner wall of the fixed ring, and the motor is fixedly mounted on the bottom of one side of the surface of the fixed ring. The output end of the motor is fixedly mounted to the forward and reverse screw. In this scheme, the cooperation of the forward and reverse screw and the motor can realize the automated control of the lifting mechanism and the lifting action of the first toothed ring. By rotating the forward and reverse screw, the two sets of threaded frames are driven to move, thereby lifting the first toothed ring so that it meshes with the second toothed ring.

[0009] Preferably, the lifting mechanism includes a threaded frame, a lifting rod, and a shaft frame. Two sets of threaded frames are provided, and the two sets of threaded frames are threadedly installed at both ends of the surfaces of the forward and reverse screws. The inner wall of the top of the threaded frame is rotatably installed with the lifting rod, and the side of the lifting rod away from the threaded frame is rotatably installed with the shaft frame. In this scheme, the coordinated use of the threaded frame, the lifting rod, and the shaft frame can achieve the function of lifting the first toothed ring by adjusting the drive of the component, ensuring that the first toothed ring can properly mesh with the second toothed ring, thereby restricting the rotation of the positioning block.

[0010] Preferably, the clamping assembly includes a first toothed ring and a second toothed ring. The first toothed ring is fixedly installed on the side of the shaft frame away from the lifting rod, and the second toothed ring is fixedly installed on the bottom of the positioning block. The first toothed ring and the second toothed ring mesh with each other. In this scheme, the cooperation of the first toothed ring and the second toothed ring can fix the positioning block by meshing with each other, preventing it from rotating during processing, and ensuring the stability and accuracy of processing.

[0011] Preferably, the connecting mechanism includes a connecting rod, a plug rod, and a socket. Several sets of connecting rods are arranged in a ring and fixedly installed on the inner wall of the first toothed ring. The side of the connecting rod away from the first toothed ring is fixedly installed with the plug rod. The socket is opened on the inner wall of the positioning block, and the plug rod is movably inserted into the socket opened at the bottom of the positioning block. In this design, the coordinated use of the connecting rod, plug rod, and socket enables precise alignment between the first toothed ring and the positioning block. Simultaneously, it prevents angular displacement of the first toothed ring when it moves up and down, ensuring that the first toothed ring is always aligned with the second toothed ring.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The butterfly valve plate processing and positioning device with multi-angle adjustment mechanism described in this utility model, through the arrangement of annular groove, roller and rotating ring, enables the rotating ring to rotate more stably by the cooperation of annular groove and roller, and at the same time, there will be no excessive friction during rotation. The rotating ring enables the positioning block to have a rotation function, thereby enabling the positioning block to have a multi-angle adjustment function, which is convenient for users to process.

[0014] 2. The butterfly valve plate processing and positioning device with multi-angle adjustment mechanism described in this utility model, through the arrangement of positioning blocks, positioning pins, forward and reverse screws and motor, enables the positioning blocks and positioning pins to cooperate in positioning the valve plate, so that the valve plate can be processed stably and the processing can be carried out normally. The cooperation of forward and reverse screws and motor enables automated control of the lifting mechanism and the lifting action of the first toothed ring. The rotation of the forward and reverse screws drives the two sets of threaded frames to move, thereby lifting the first toothed ring so that it can mesh with the second toothed ring.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 6As shown in the embodiment of this utility model, a butterfly valve plate processing and positioning device with a multi-angle adjustment mechanism includes a base plate 1; a fixing ring 2 is fixedly installed on the top of the base plate 1, a support mechanism 3 is provided on the inner wall of the fixing ring 2, and a positioning component 4 is provided on the inner wall of the fixing ring 2; an adjustment component 5 is provided on the bottom of the inner wall of the fixing ring 2, and a lifting mechanism 6 is provided on the inner wall of the fixing ring 2; a clamping component 7 is provided on the bottom of the positioning block 41, and a connecting mechanism 8 is provided on the bottom of the positioning block 41; the support mechanism 3 includes an annular groove 31, a roller 32, and a rotating ring 33, and the annular groove 31 is formed with... In the middle of the inner wall of the fixed ring 2, several sets of rollers 32 are arranged, and the several sets of rollers 32 are installed in annular grooves 31 opened in the inner wall of the fixed ring 2. The rotating ring 33 is rotatably installed in the annular grooves 31 opened in the inner wall of the fixed ring 2, and the rollers 32 are located on the surface of the rotating ring 33. The positioning component 4 includes a positioning block 41 and a positioning pin 42. The positioning block 41 is fixedly installed in the inner wall of the rotating ring 33, and several sets of positioning pins 42 are arranged, and the several sets of positioning pins 42 are fixedly installed in annular shape on the top of the positioning block 41. The adjusting component 5 includes a forward and reverse screw 51 and a motor 52. The reverse screw 51 is rotatably mounted on the bottom of the inner wall of the fixed ring 2. The motor 52 is fixedly mounted on the bottom of one side of the surface of the fixed ring 2. The output end of the motor 52 is fixedly mounted to the forward and reverse screw 51. The lifting mechanism 6 includes a threaded frame 61, a lifting rod 62, and a shaft frame 63. Two sets of threaded frames 61 are provided, and the two sets of threaded frames 61 are threadedly mounted on both ends of the surface of the forward and reverse screw 51. The inner wall of the top of the threaded frame 61 is rotatably mounted to the lifting rod 62. The side of the lifting rod 62 away from the threaded frame 61 is rotatably mounted to the shaft frame 63. The clamping assembly 7 includes a first toothed ring 71 and a second toothed ring 72. The first toothed ring 71 is fixedly installed on the side of the shaft frame 63 away from the lifting rod 62, and the second toothed ring 72 is fixedly installed on the bottom of the positioning block 41. The first toothed ring 71 and the second toothed ring 72 mesh with each other. The connecting mechanism 8 includes a connecting rod 81, a plug rod 82 and a plug hole 83. Several sets of connecting rods 81 are provided. Several sets of connecting rods 81 are fixedly installed in a ring on the inner wall of the first toothed ring 71. The side of the connecting rod 81 away from the first toothed ring 71 is fixedly installed with the plug rod 82. The plug hole 83 is opened on the inner wall of the positioning block 41. The plug rod 82 is movably inserted into the plug hole 83 opened at the bottom of the positioning block 41.

[0027] like Figures 1 to 6As shown, the cooperation between the annular groove 31 and the roller 32 makes the rotation of the rotating ring 33 more stable, and at the same time, it will not cause excessive friction during rotation. The rotating ring 33 enables the positioning block 41 to have a rotation function, thereby enabling the positioning block 41 to have a multi-angle adjustment function, which is convenient for users to process. The cooperation between the positioning block 41 and the positioning pin 42 can position the valve plate, so that the valve plate can be processed stably and the processing can be carried out normally. The cooperation between the forward and reverse screws 51 and the motor 52 can realize the automatic control of the lifting mechanism 6 and the lifting action of the first toothed ring 71. The rotation of the forward and reverse screws 51 drives the two sets of threaded frames 61 to move, thereby lifting the first toothed ring 71 so that it can mesh with the second toothed ring 72. The combined use of the threaded bracket 61, lifting rod 62, and shaft bracket 63 can lift the first toothed ring 71 by adjusting the drive of the component 5, ensuring that the first toothed ring 71 can properly mesh with the second toothed ring 72, thereby limiting the rotation of the positioning block 41. The combined use of the first toothed ring 71 and the second toothed ring 72 can fix the positioning block 41 by meshing with each other, preventing it from rotating during processing, ensuring the stability and accuracy of processing. The combined use of the connecting rod 81, insert rod 82, and insert hole 83 can ensure that the first toothed ring 71 and the positioning block 41 can be precisely aligned. At the same time, it can also prevent the first toothed ring 71 from shifting at an angle when it moves up and down, ensuring that the first toothed ring 71 can always be aligned with the second toothed ring 72.

[0028] Working principle: During operation, the base plate 1 is first placed on a flat surface. Then, the user places the valve plate in the positioning block 41 for positioning. When the angle of the valve plate needs to be adjusted, the user only needs to rotate the positioning block 41 to adjust the angle to any value. When the appropriate angle is reached, the user only needs to start the motor 52 to drive the forward and reverse screws 51 to rotate. When the forward and reverse screws 51 rotate, they will drive the two sets of threaded brackets 61 to move towards the two ends of the forward and reverse screws 51. When the threaded brackets 61 move, the lifting rod 62 will rotate on the inner wall of the threaded brackets 61. At the same time, as the threaded brackets 61 move continuously, the lifting rod 62 will slowly lift the shaft bracket 63 and the first toothed ring 71 upward. When the first toothed ring 71 is lifted, it will lock with the second toothed ring 72. At that time, the positioning block 41 will no longer have the function of rotation. Therefore, it can prevent the valve plate from rotating during processing.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
