Description

Technical Field

[0001] The present invention relates to the field of solenoid valve grinding, and specifically to a grinding device for the production of solenoid valve housings. Background Technique

[0002] A solenoid valve is a device that controls the on-off of fluid through an electromagnetic system. It is widely used in fields such as industrial automation and fluid control. It is mainly used to adjust the direction, flow rate, speed, and other parameters of the medium, and can cooperate with different circuits to achieve precise and flexible control.

[0003] When producing a solenoid valve housing, its surface needs to be processed. During the grinding process, various tools and materials are used, such as sandpaper, grinding heads, and polishing paste. Grinding is carried out with appropriate force and angle to ensure that the surface of the housing is smooth and free of burrs, so as to improve its appearance quality, corrosion resistance, and service life. Existing grinding devices all use clamping parts to clamp and position the surface of the solenoid valve housing, and adjust the surface angle of the solenoid valve housing by rotating the clamping parts. Although the surface of the solenoid valve housing can be ground at multiple angles, the contact surface between the clamping part and the solenoid valve cannot be ground. It is necessary to remove the solenoid valve from the clamping part before it can be replaced to grind at another position, resulting in poor grinding efficiency. Moreover, the temperature of the solenoid valve housing after grinding is relatively high, and the safety is poor. Summary of the Invention

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figures 1 - 8 , a grinding device for the production of an electromagnetic valve housing shown in the figure, including a ring-shaped bracket 1 and a mounting bracket 2 fixedly installed on the outer side of the ring-shaped bracket 1. An electric grinding disc 3 is installed on the outer side of the mounting bracket 2. By adjusting the position of the electric grinding disc 3 through the mounting bracket 2, it is convenient to grind the surface of the electromagnetic valve housing. Four clamping plates 4 are arranged on the outer side of the ring-shaped bracket 1 and are symmetrically distributed around the center. The two horizontally distributed clamping plates 4 are used to clamp both sides of the electromagnetic valve housing, and the two vertically distributed clamping plates 4 are used to clamp the top and bottom of the electromagnetic valve housing. A plurality of anti-slip lines are arranged at equal intervals on the outer side of the clamping plate 4 to increase the friction between the clamping plate 4 and the electromagnetic valve housing. An adjusting cylinder 5 is arranged on the outer side of the clamping plate 4. The number of adjusting cylinders 5 is the same as that of the clamping plates 4 and the positions correspond. A ring-shaped socket 6 is rotatably installed on the outer side of the adjusting cylinder 5, and the ring-shaped socket 6 is fixedly installed on the outer side of the ring-shaped bracket 1 to provide positioning for the adjusting cylinder 5; further includes: a clamping mechanism for clamping the surface of the electromagnetic valve housing at multiple angles, and the clamping mechanism is installed inside the adjusting cylinder 5; an anti-detachment mechanism for supporting the electromagnetic valve housing to prevent it from falling off, and the anti-detachment mechanism is installed on the outer side of the ring-shaped bracket 1; a position-adjusting mechanism for positioning and straightening the electromagnetic valve housing, and the position-adjusting mechanism is installed on the outer side of the ring-shaped bracket 1.

[0031] The clamping mechanism includes a U-shaped frame 8 fixedly installed on the outer side of the adjusting cylinder 5. Rotating the U-shaped frame 8 can drive the adjusting cylinder 5 to rotate. A first screw rod 9 is rotatably installed between the inner sides of the U-shaped frame 8 and the adjusting cylinder 5. A first moving block 10 matched with the first screw rod 9 is arranged on the inner side of the adjusting cylinder 5. A plurality of first optical axes 11 symmetrically distributed are fixedly installed on the inner side of the adjusting cylinder 5. The first moving block 10 is slidably installed on the outer side of the first optical axes 11. When the first screw rod 9 is rotated, the first moving block 10 can be driven to move along the outer side of the first optical axes 11. A plurality of sleeves 12 symmetrically distributed around the center are fixedly installed on the outer side of the first moving block 10, so that the first moving block 10 drives the sleeves 12 to move synchronously. The sleeves 12 slidably penetrate through the adjusting cylinder 5. A slide rod 13 is slidably installed inside the sleeve 12. A first spring 14 is fixedly installed between the slide rod 13 and the inner side of the sleeve 12. One end of the slide rod 13 away from the first spring 14 is fixedly connected to the adjacent clamping plate 4, so that the sleeve 12 can drive the clamping plate 4 to move through the slide rod 13, and by using the elasticity of the first spring 14, the outer side of the solenoid valve housing can be elastically clamped by the clamping plate 4 to prevent excessive pressure. And by rotating the adjusting cylinder 5, the sleeve 12 can drive the clamping plate 4 to move through the slide rod 13, and the clamping plate 4 can drive the solenoid valve housing to rotate. A magnet block 40 is fixedly installed at one end of the slide rod 13 close to the first spring 14. The inner side of the sleeve 12 is made of copper. By using the electromagnetic damping characteristic between the magnet block 40 and the first spring 14, the situation that the first spring 14 rebounds too fast during reset can be prevented. The thread directions of the two first screw rods 9 at the top and bottom of the annular bracket 1 are opposite to the thread directions of the two first screw rods 9 on both sides of the annular bracket 1. A rotating ring 15 is rotatably installed on the outer side of the annular bracket 1. A first bevel gear 16 is fixedly installed at one end of the first screw rod 9 close to the U-shaped frame 8. Four arc-shaped strips 17 symmetrically distributed around the center are fixedly installed on the outer side of the rotating ring 15. First racks matched with the first bevel gear 16 are provided on the surfaces of the four arc-shaped strips 17. When the rotating ring 15 rotates, the four corresponding first bevel gears 16 can be driven to rotate synchronously through the first racks on the four arc-shaped strips 17. Since the thread directions of the two first screw rods 9 at the top and bottom of the annular bracket 1 are opposite to the thread directions of the two first screw rods 9 on both sides of the annular bracket 1, when the two horizontally distributed clamping plates 4 approach the solenoid valve housing, the two vertically distributed clamping plates 4 move away from the solenoid valve housing. Similarly, when the two vertically distributed clamping plates 4 approach the solenoid valve housing, the two horizontally distributed clamping plates 4 move away from the solenoid valve housing. A first handle 37 is fixedly installed on one side of the U-shaped frame 8 away from the adjusting cylinder 5, which is convenient for rotating the adjusting cylinder 5 to realize the rotary grinding of the solenoid valve housing. A second handle 38 is rotatably installed on the outer side of the annular bracket 1. An adjusting gear 39 is fixedly installed at one end of the second handle 38. A second rack matched with the adjusting gear 39 is provided on the inner side of the rotating ring 15. The staff can drive the adjusting gear 39 to rotate by rotating the second handle 38.The adjusting gear 39 drives the rotating ring 15 to rotate through the second rack.

[0032] Embodiment 2: Please refer to Figures 1 - 6 , this embodiment further illustrates Embodiment 1. The anti-detachment mechanism in the figure includes two mounting cylinders 18 symmetrically and fixedly installed on the outside of the annular bracket 1. The mounting cylinders 18 are in an inclined state. A second screw 19 is rotatably installed inside the mounting cylinder 18. One end of the second screw 19 extends to the outside of the mounting cylinder 18 and is fixedly installed with a second bevel gear 20. When the first rack on the arc-shaped strip 17 contacts the second bevel gear 20, it can drive the second bevel gear 20 to rotate. The second bevel gear 20 can drive the second screw 19 to rotate. A second moving block 21 is arranged inside the mounting cylinder 18 and is matched with the second screw 19. A second optical axis 22 that slidably penetrates the second moving block 21 is fixedly installed inside the mounting cylinder 18. When the second screw 19 rotates, it can drive the second moving block 21 to move along the outside of the second optical axis 22. Two symmetrically distributed support rods 23 are fixedly installed on the outside of the second moving block 21. The second moving block 21 can drive the support rods 23 to move synchronously. The support rods 23 slidably penetrate the mounting cylinder 18. A placement plate 24 is fixedly installed between the two support rods 23. The staff can place the solenoid valve housing on the two placement plates 24. After the two horizontally distributed clamping plates 4 clamp and position the solenoid valve housing, rotate the rotating ring 15 again, so that the rotating ring 15 drives the second bevel gear 20 to rotate through the first rack on the arc-shaped strip 17, and the two placement plates 24 can move away from the solenoid valve housing, facilitating the clamping plates 4 to drive the solenoid valve housing to rotate. A plurality of sliding balls 41 are rotatably installed on the top of the placement plate 24. When the two vertically distributed clamping plates 4 clamp and position the top and bottom of the solenoid valve housing, it can drive the solenoid valve housing to rotate on the sliding balls 41, preventing wear on the solenoid valve housing.

[0033] Embodiment 3: Please refer to Figure 5 and Figure 8, this embodiment further illustrates other embodiments. The positioning mechanism in the figure includes a side push plate 25 arranged on the top of the placement plate 24. When the placement plate 24 contacts the solenoid valve housing, it can drive the side push plate 25 to contact the outer side of the solenoid valve housing. Two symmetrically distributed L-shaped sliding plates 26 are fixedly installed at the bottom of the side push plate 25. A sliding cavity for the L-shaped sliding plates 26 to be limited and slide is opened inside the placement plate 24. A tension spring 27 is fixedly installed between the inner side of the sliding cavity and the L-shaped sliding plates 26. The reaction force of the solenoid valve housing on the side push plate 25 pushes the side push plate 25 to move, causing the side push plate 25 to push the L-shaped sliding plates 26 to move along the sliding cavity of the placement plate 24 and stretch the tension spring 27. A shaft seat 28 is fixedly installed on the inner side of the sliding cavity of the placement plate 24. A ratchet wheel 29 is rotatably installed on the outer side of the shaft seat 28. Driven gears 30 are fixedly installed on both sides of the ratchet wheel 29. A rack plate 31 that cooperates with the driven gears 30 is fixedly installed at the bottom of the L-shaped sliding plates 26. When the L-shaped sliding plates 26 move, they can drive the driven gears 30 to rotate through the rack plate 31, causing the driven gears 30 to drive the ratchet wheel 29 to rotate. An installation plate 32 is arranged inside the placement plate 24. Two second springs 33 are fixedly installed between the installation plate 32 and the inner side of the sliding cavity of the placement plate 24. A tooth 34 that cooperates with the ratchet wheel 29 is fixedly installed at the bottom of the installation plate 32. The tooth 34 uses the elasticity of the second spring 33 to provide one-way locking for the ratchet wheel 29. A plug rod 35 is arranged inside the second spring 33. A slot for the plug rod 35 to be limited and slide is opened inside the placement plate 24 to provide guidance for the movement of the installation plate 32 and prevent skewing. A push rod 36 is fixedly installed at one end of the installation plate 32 away from the tooth 34. The end of the push rod 36 away from the installation plate 32 is of a hemispherical structure. A frustum 7 is fixedly installed at one end of the installation cylinder 18 close to the placement plate 24. When the push rod 36 contacts the frustum 7, it pushes the push rod 36 to move, unlocking the ratchet wheel 29 by the tooth 34 and resetting it using the tension spring 27. Two symmetrically distributed guide rods 42 are fixedly installed on the inner side of the sliding cavity of the placement plate 24. The two guide rods 42 respectively slide through the two L-shaped sliding plates 26, enabling the L-shaped sliding plates 26 to move along the outer sides of the guide rods 42, improving the smoothness of the movement of the L-shaped sliding plates 26.

[0034] Working principle: First, the staff places the solenoid valve housing to be polished between the two placement plates 24. Then, the staff rotates the second handle 38, causing the second handle 38 to drive the adjusting gear 39 to rotate. The adjusting gear 39 drives the rotating ring 15 to rotate clockwise through the second rack. The rotating ring 15 drives the four arc-shaped bars 17 to perform a clockwise circular motion, causing the four arc-shaped bars 17 to drive the corresponding four first bevel gears 16 to rotate. The first bevel gear 16 drives the first screw rod 9 to rotate, causing the first screw rod 9 to drive the first moving block 10 to move along the outer side of the first optical axis 11. The first moving block 10 drives the sleeve 12 to move synchronously, causing the sleeve 12 to drive the clamping plate 4 through the slide rod 13. Since the thread directions of the two first screw rods 9 at the top and bottom of the annular bracket 1 are opposite to the thread directions of the two first screw rods 9 on both sides of the annular bracket 1, the two horizontally distributed clamping plates 4 can approach the outer side of the solenoid valve housing, and the two vertically distributed clamping plates 4 move away from the solenoid valve housing. At the same time, using the reaction force of the solenoid valve housing on the clamping plate 4, the clamping plate 4 pushes the slide rod 13 to compress the first spring 14 of the sleeve 12, enabling the two clamping plates 4 to elastically clamp both sides of the solenoid valve housing. Subsequently, the staff rotates the rotating ring 15 clockwise again, causing the rotating ring 15 to move away from the first bevel gear 16 through the arc-shaped bar 17 and come into contact with the second bevel gear 20. The second bevel gear 20 is driven to rotate by the first rack, and the second bevel gear 20 drives the second moving block 21 to move along the outer side of the second optical axis 22, causing the second moving block 21 to drive the placement plate 24 to move away from the solenoid valve housing through the support rod 23. At this time, when the staff rotates any one of the horizontally distributed U-shaped frames 8, the sleeve 12 can be driven to rotate through the adjusting cylinder 5, causing the sleeve 12 to drive the clamping plate 4 to rotate through the slide rod 13. The clamping plate 4 can then rotate the clamped and positioned solenoid valve housing, and the electric grinding disc 3 is started to polish the outer side of the solenoid valve housing. After the polishing is completed, the staff rotates the rotating ring 15 counterclockwise, causing the arc-shaped bar 17 to drive the second bevel gear 20 to rotate and reset. The placement plate 24 approaches the bottom of the solenoid valve housing, and the side push plate 25 on the placement plate 24 comes into contact with the outer side of the solenoid valve housing. Using the reaction force of the solenoid valve housing on the side push plate 25, the side push plate 25 is pushed to move, causing the side push plate 25 to push the L-shaped sliding plate 26 to move within the sliding cavity of the placement plate 24 and stretch the tension spring 27. At the same time, the L-shaped sliding plate 26 drives the rack plate 31 to move synchronously, causing the rack plate 31 to drive the ratchet wheel 29 to rotate through the driven gear 30. When the ratchet wheel 29 stops rotating, the second spring 33's elasticity is used to lock the ratchet wheel 29 with the tooth 34. The side push plate 25 is adjusted to the corresponding position according to the size of the solenoid valve housing, placing the solenoid valve housing in the middle position between the two placement plates 24. Subsequently, the arc-shaped bar 17 moves away from the second bevel gear 20 and comes into contact with the first bevel gear 16, causing the two horizontally distributed clamping plates 4 to move away from the solenoid valve housing. As the rotating ring 15 continues to rotate in the reverse direction, the two vertically distributed clamping plates 4 can clamp and position the top and bottom of the solenoid valve housing.Under the positioning of the two side push plates 25, the solenoid valve housing is in the middle position between the two clamping plates 4. Finally, the operator rotates any one of the two vertically distributed U-shaped frames 8, which can drive the solenoid valve housing to rotate, so that the electric grinding disc 3 grinds both sides of the solenoid valve housing, thereby achieving comprehensive grinding of the solenoid valve housing. During the process, there is no need to remove the solenoid valve housing, thus achieving the effect of comprehensive and safe grinding.
