Description

Technical Field

[0001] The invention relates to the technical field of valve processing equipment, in particular to a grinding device used for valve production. Background Art

[0002] During the production process of valve body forgings, the initial surface of the formed valve body forgings is relatively rough, and in order to make the surface smooth and bright, it is necessary to use a grinding device to grind it. Most of the devices for grinding valves in the prior art clamp the valve body and grind the outer wall of the valve body.

[0003] For example, a valve body production all-round grinding device disclosed in publication number CN116787286B can automatically grind the upper surface and left and right surfaces of the valve body through the provided grinding components, and as the moving component pushes the valve body forward, the grinding device on the opposite side automatically contracts inward to contact and grind the valve body, and the grinding belt can change its angle when contacting the valve body, so as to wrap the surface of the valve body and realize friction grinding of multiple aspects of the surface, thereby realizing automatic grinding of the valve body, improving grinding efficiency, reducing labor input, and directly avoiding the operator from inhaling dust into the body during manual grinding, as well as safety issues during grinding.

[0004] However, Figure 8 As shown, the shape of the outer wall of the valve body is not a regular shape, and the fixed valve body and the grinding structure cannot effectively grind the arc or inclined position of the valve body surface, resulting in poor valve body processing effect and affecting the quality of the valve body product. In view of this, we propose a grinding device for valve production. Summary of the invention

DETAILED DESCRIPTION

[0034] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] A grinding device for valve production, such as Figure 1-Figure 7 As shown, it includes a workbench 1; a grinding mechanism 2 is provided on one side of the workbench 1 for grinding the surface of the valve body. The grinding mechanism 2 can remove burrs on the surface of the blank.

[0037] Specifically, the grinding mechanism 2 includes a lifting platform 21, which is slidably connected to the side of the workbench 1. The lifting platform 21 can be lifted and moved, so as to perform grinding and processing operations on different positions of the valve body. A control block 22 is slidably connected to the lifting platform 21, and a support plate 23 is rotatably connected to the top of the control block 22 and the top of the lifting platform 21. A grinding belt 24 is sleeved on the outer side of the support plate 23. The control block 22 structure can control or adjust the position of the support plate 23. At the same time, a buffer spring is fixedly connected to the inner side of the control block 22. The buffer spring can control the movement of the control block 22 through elasticity, so that the grinding belt 24 is in a taut state. At the same time, the support plate 23 structure can support the grinding belt 24, so that the continuously rotating grinding belt 24 can grind and process the valve body surface of different shapes. A positioning platform 25 is slidably connected to the bottom end of the lifting platform 21. The positioning platform 25 can position the horizontal position of the lifting platform 21, so as to conveniently adjust the position between the grinding belt 24 and the valve body.

[0038] Furthermore, the lifting platform 21 is fixedly connected with a support frame 26, and a dual-axis motor 27 is connected to the support frame 26. The support frame 26 structure can support the dual-axis motor 27, so that the dual-axis motor 27 remains stable during operation. The output shaft at one end of the dual-axis motor 27 is fixedly connected to the support plate 23, and the support plate 23 structure can be driven by the output shaft at one end of the dual-axis motor 27, so that the support plate 23 can drive the grinding belt 24 to rotate continuously, thereby realizing the grinding operation of the valve body. The positioning platform 25 is rotatably connected with a screw rod 28, and the screw rod 28 is meshed with the positioning platform 25. The meshed screw rod 28 can drive the positioning platform 25 and the lifting platform 21 by rotating itself, thereby realizing the lifting and lowering adjustment of the lifting platform 21. At the same time, a guide rod is connected to the positioning platform 25, and the guide rod is arranged in parallel with the screw rod 28. The guide rod can prevent the lifting platform 21 from rotating with the screw rod 28 when the screw rod 28 drives the positioning platform 25. A driving handle 29 is fixedly connected to the top of the screw rod 28, and the driving handle 29 can drive the screw rod 28 so that the screw rod 28 is driven to rotate under the action of external force.

[0039] In addition, a supporting mechanism 3 is provided on the other side of the workbench 1 for supporting and fixing the valve body. Meanwhile, the supporting mechanism 3 can rotate and adjust the clamped and fixed valve body on the vertical plane, so as to perform grinding and processing operations on different angles of the valve body.

[0040] On this basis, the support mechanism 3 includes a support seat 31, which is fixedly connected to the other side of the workbench 1. The support seat 31 is a C-shaped semicircular structure. When supporting the valve body, the clamped valve body can be rotated on the vertical plane, so as to perform grinding and processing operations on different angles of the valve body. A support rod 32 is slidably connected to the support seat 31, and a clamping assembly 33 is connected to the end of the support rod 32. The support rod 32 structure can support the clamping assembly 33. A guide groove 34 is opened on the side of the support seat 31, and a guide block 35 is slidably connected inside the guide groove 34. The guide block 35 is fixedly connected to the side of the support rod 32. The guide groove 34 structure can cooperate with the guide block 35 structure to guide the movement and adjustment of the support rod 32.

[0041] It is worth noting that the clamping assembly 33 includes a clamping seat 331, and a clamping rod 332 is rotatably connected to the clamping seat 331. The structure of the clamping rod 332 can cooperate with the clamping seat 331 to stably clamp the valve body. There are three or four clamping rods 332. When the clamping rod 332 rotates toward the clamping seat 331, it can cooperate with the clamping seat 331 to achieve a stable clamping effect. The outer end of the clamping rod 332 is fixedly connected to a clamping block 334, which is made of rubber. While reducing the damage of the clamping rod 332 to the inner side of the valve body, it can improve the clamping and fixing effect of the valve body. The inner side of the clamping rod 332 is rotatably connected to a connecting rod 335, and the end of the connecting rod 335 is rotatably connected to a control rod 336. The control rod 336 is arranged through the support rod 32. The connecting rod 335 structure can synchronously control multiple clamping rods 332. The movement of the control rod 336 can drive the connecting rod 335 to rotate, and the end of the connecting rod 335 is rotated around the hinge point between the connecting rod 335 and the control rod 336, so as to realize the clamping function of the end of the clamping rod 332 on the valve body. The outer side of the control rod 336 is fixedly connected to a return spring 333, and the return spring 333 can drive the control rod 336 through elasticity, thereby using the elasticity of the return spring 333 to drive the clamping rod 332. At the same time, in actual use, the return spring 333 can be replaced by a piston or damper with the same function.

[0042] In addition, the support seat 31 is slidably connected to a drive frame 36 on the side, and a drive slot 37 is provided inside the drive frame 36. The guide block 35 is slidably connected inside the drive slot 37. The drive frame 36 can use the drive slot 37 to adjust the position of the guide block 35, thereby controlling the angle of the support rod 32. The drive frame 36 is rotatably connected to a drive block on the side, and the drive block can support the drive frame 36. At the same time, a torsion spring is fixedly connected to the connection between the drive frame 36 and the drive block, so that the drive frame 36 can be reset to the initial state. At the same time, the drive frame 36 of the rotating structure can move the guide block 35 downward from the top of the support seat 31 or upward from the bottom, so as to avoid the guide block 35 being restricted by the support seat 31 and being stuck in movement. In addition, the drive slot 37 is a trapezoidal structure, and the end of the drive slot 37 close to the drive block is narrower, and the end away from the drive block is wider, so that the top of the drive slot 37 and the bottom of the drive slot 37 form an inclined surface, which is convenient for resetting the guide block 35 to the highest point or the lowest point. A screw rod 38 is rotatably connected to the workbench 1 . The screw rod 38 passes through the driving block. The screw rod 38 is meshed with the driving block. The screw rod 38 structure can drive the driving block, thereby controlling the rotation of the support rod 32 .

[0043] Example 2

[0044] like Figure 1 , Figure 5 , Figure 7As shown, on the basis of Example 1, an angle adjustment mechanism 4 is provided on the support mechanism 3 for adjusting the clamping angle of the valve body. The angle adjustment mechanism 4 can control the horizontal rotation angle of the valve body, so that it can cooperate with the support mechanism 3 to perform grinding operations on different positions of the valve body.

[0045] In this embodiment, the angle adjustment mechanism 4 includes an angle adjustment rod 41, which is rotatably connected to the inside of the support rod 32, and the end of the angle adjustment rod 41 is fixedly connected to the clamping seat 331. The angle adjustment rod 41 can conveniently adjust the angle of the clamping seat 331 by rotating itself. At the same time, the angle adjustment rod 41 is a hollow structure, and the control rod 336 is connected to the inside of the angle adjustment rod 41. The end of the angle adjustment rod 41 is movably connected with an adjustment knob 42, and the adjustment knob 42 structure can control the angle adjustment rod 41. At the same time, the inside of the angle adjustment rod 41 is a non-cylindrical structure, and the inner structure of the adjustment knob 42 corresponds to the structure of the angle adjustment rod 41. Therefore, the adjustment knob 42 can drive the angle adjustment rod 41 to rotate while sliding at the end of the angle adjustment rod 41. In addition, the end of the control rod 336 is fixedly connected to the inner side of the adjustment knob 42, and the opening of the clamping rod 332 and the clamping of the valve body can be controlled by moving the adjustment knob 42.

[0046] Example 3

[0047] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, on the basis of Example 1, a waste collection mechanism 5 is provided at the end of the output shaft at the other end of the dual-axis motor 27 for collecting the debris generated during processing to prevent the debris from floating in the air and affecting the health of the operator, and also to prevent the debris from falling on the surface of the workbench 1 and being difficult to collect and process.

[0048] On this basis, the waste collection mechanism 5 includes an exhaust fan 55, which is connected to the end of the output shaft at the other end of the dual-axis motor 27. The exhaust fan 55 connected to the dual-axis motor 27 can collect debris simultaneously during grinding. At the same time, a filter can be set inside the exhaust fan 55 in actual use to prevent debris from escaping from the exhaust pipe 54 into the air. The exhaust fan 55 is a negative pressure fan, which can extract the gas inside the collection box 53, so that the collection box 53 and the collection pipe 52 form a negative pressure environment, thereby improving the collection effect of debris. An exhaust pipe 54 is sleeved on the outside of the exhaust fan 55, and the exhaust pipe 54 is fixed on the support frame 26, and can be moved and adjusted with the dual-axis motor 27. The end of the exhaust pipe 54 is connected to a collection box 53, and the collection box 53 is fixedly connected to the workbench 1. The collection box 53 structure can collect and store debris.

[0049] In this embodiment, the waste collection mechanism 5 also includes a collection hood 51 movably connected to the top of the workbench 1. The collection hood 51 is a trumpet-shaped structure, which is convenient for collecting the generated debris. The collection hood 51 is movably connected to the top of the workbench 1. The movably connected collection hood 51 can easily adjust the position of the collection hood 51 to meet the processing operation requirements at different positions. At the same time, the collection hood 51 can be set at the top of the support plate 23 and connected to the support plate 23 through a rod-shaped structure, so that it can be kept on both sides of the grinding processing site during the processing operation, which is convenient for the collection operation. The back of the collection hood 51 is connected to a collection pipe 52, and the collection pipe 52 structure can guide the collected debris. The end of the collection pipe 52 is fixedly connected to the side of the collection box 53.

[0050] When the polishing device for valve production of the present invention is used, the adjusting knob 42 is first pulled out, and the adjusting knob 42 drives the control rod 336 to move synchronously, and the connecting rod 335 at the end of the control rod 336 moves synchronously with the moving rod and rotates the clamping rod 332 inward, and the ends of the clamping rod 332 are close to each other. Then, one end of the valve body to be processed is moved to the outside of the clamping rod 332, and the clamping rod 332 is inserted into the inside of the valve body and then the adjusting knob 42 is released. The control rod 336 is reset under the elastic drive of the reset spring 333, and the clamping rod 332 rotates in the opposite direction, and the ends of the clamping rod 332 are separated from each other and the inner wall of the valve body is clamped and fixed by the clamping block 334. The inner wall of the valve body is a rough surface with threads, so it will not be separated from the clamping assembly 33 during the clamping process. At the same time, the rubber clamping block 334 can cooperate with the rough inner wall of the valve body to drive the valve body to rotate. At the same time, since the clamping rod 332 rotates outward, the clamping rod 332 inclined outward provides a force to the valve body in the direction of the clamping seat 331, and the clamping rod 332 cooperates with the clamping seat 331 to clamp and fix the valve body. The vertical angle of the valve body is then adjusted, and the drive block moves accordingly after the screw rod 38 is rotated. When the support rod 32 is in a vertical state, that is, the guide block 35 is at the highest point or the lowest point of the guide groove 34, since the force of the drive frame 36 driving the guide block 35 is a vertical force, the movement of the guide block 35 is restricted by the support seat 31. At this time, the drive block drives the drive frame 36 to rotate after moving until the guide block 35 moves to the end of the drive groove 37. At this time, the drive frame 36 is in an inclined state, and the drive frame 36 that continues to move downward with the drive block rotates accordingly and drives the guide block 35 outward to move. When it moves to the set position, it can stop rotating, thereby completing the adjustment of the vertical direction of the valve body. Subsequently, the control rod 336 is rotated by adjusting the knob 42, and the angle adjustment rod 41 rotates accordingly and drives the clamping seat 331 at the end and the clamping assembly 33 to rotate synchronously, so that the horizontal angle of the valve body can be adjusted. Then the dual-axis motor 27 can be started, and the dual-axis motor 27 drives the support plate 23 and the exhaust fan 55 respectively, and the grinding belt 24 on the support plate 23 rotates accordingly, and the exhaust fan 55 extracts the air inside the collection box 53, so that a negative pressure environment is formed inside the collection box 53. Then the screw 28 is rotated by the driving handle 29 to lift the positioning table 25 and the lifting platform 21 to the set position, and the lifting platform 21 is moved toward the valve body, and the valve body surface is polished by the continuously rotating grinding belt 24. During the polishing process, the collection box 53 in the negative pressure environment sucks the debris generated by the polishing into the collection box 53 through the collection tube 52 and the collection cover 51. During the polishing process, the vertical angle or horizontal angle of the valve body can be adjusted and rotated to meet the polishing processing requirements of different angles or different curvatures of the outer wall of the valve body.
