Description

Technical Field

[0001] The invention relates to the field of electromagnetic valve polishing, in particular to a polishing device for producing an electromagnetic valve shell. Background Art

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

[0003] When the solenoid valve shell is produced, its surface needs to be processed. Various tools and materials, such as sandpaper, grinding heads and polishing paste, are used in the grinding process. The shell surface is polished with appropriate force and angle to ensure that it is smooth and burr-free, so as to improve its appearance quality, corrosion resistance and service life. The existing polishing devices all use clamps to clamp and position the surface of the solenoid valve shell, and adjust the surface angle of the solenoid valve shell by rotating the clamp. Although the surface of the solenoid valve shell can be polished at multiple angles, the contact surface between the clamp and the solenoid valve cannot be polished. The solenoid valve needs to be removed from the clamp before it can be replaced for polishing. The polishing efficiency is poor, and the temperature of the solenoid valve shell after polishing is high, and the safety is poor. Summary of the invention

Two symmetrically distributed support rods 23 are fixedly installed on the outer side of the moving block 21. The second moving block 21 can drive the support rods 23 to move synchronously. The support rods 23 slide and penetrate the installation tube 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, and after the two horizontally distributed clamping plates 4 clamp the solenoid valve housing and position it, rotate the swivel 15 again, so that the swivel 15 drives the second bevel gear 20 to rotate through the first rack on the arc bar 17, and the two placement plates 24 can be away from the solenoid valve housing, which is convenient for the clamping plates 4 to drive the solenoid valve housing to rotate.

Two symmetrically distributed L-shaped slide plates 26 are fixedly installed at the bottom of the side push plate 25. A sliding cavity for limiting the sliding of the L-shaped slide plate 26 is opened on the inner side of the placement plate 24. A tension spring 27 is fixedly installed between the inner side of the sliding cavity and the L-shaped slide plate 26, so that the reaction force of the solenoid valve housing on the side push plate 25 pushes The side push plate 25 moves, so that the side push plate 25 pushes the L-shaped slide plate 26 to move along the sliding cavity of the placement plate 24, and stretches the tension spring 27. The inner side of the sliding cavity of the placement plate 24 is fixedly installed with an axle seat 28, and the outer side of the axle seat 28 is rotatably installed with a ratchet 29. Both sides of the ratchet 29 are fixedly installed with a driven gear 30. The bottom of the L-shaped slide plate 26 is fixedly installed with a rack plate 31 that matches the driven gear 30. When the L-shaped slide plate 26 moves, it can drive the driven gear 30 to rotate through the rack plate 31, so that the driven gear 30 drives the ratchet 29 to rotate, and the placement plate 24 A mounting plate 32 is provided on the inner side of the mounting plate 32, and two second springs 33 are fixedly installed between the mounting plate 32 and the inner side of the sliding cavity of the placement plate 24.

The end of the mounting tube 18 close to the placement plate 24 is fixedly installed with a round table 7, so that when the push rod 36 contacts the round table 7, it pushes the push rod 36 to move, so that the locking tooth 34 unlocks the ratchet 29 and is reset by 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 slide through the two L-shaped slides 26 respectively, so that the L-shaped slide 26 can move along the outer side of the guide rods 42, thereby improving the stability of the movement of the L-shaped slide 26.

[0034] Working principle: First, the staff places the solenoid valve housing to be polished between the two placement plates 24, and then the staff turns the second handle 38, so that the second handle 38 drives the adjusting gear 39 to rotate, and the adjusting gear 39 drives the rotating ring 15 to rotate clockwise through the second rack, and the rotating ring 15 drives the four arc bars 17 to make clockwise circular motion, so that the four arc bars 17 drive the corresponding four first bevel gears 16 to rotate, and the first bevel gear 16 drives the first screw 9 to rotate, so that the first screw 9 drives the first moving block 10 to move along the outside of the first optical axis 11, and the first moving block 10 drives the sleeve 12 to move synchronously, so that the sleeve 12 drives the clamping plate 4 to move through the sliding rod 13. Due to the threaded squares of the two first screws 9 located at the top and bottom of the annular bracket 1 In the opposite direction of the thread direction of the two first screw rods 9 located on both sides of the annular bracket 1, the two horizontally distributed clamping plates 4 can be close to the outer side of the solenoid valve housing, and the two vertically distributed clamping plates 4 are away from the solenoid valve housing. At the same time, the reaction force of the solenoid valve housing on the clamping plates 4 is used to make the clamping plates 4 push the sliding rod 13 to compress the first spring 14 of the sleeve 12, so that the two clamping plates 4 elastically clamp the two sides of the solenoid valve housing. Subsequently, the staff rotates the swivel 15 clockwise again, so that the swivel 15 is away from the first bevel gear 16 through the arc bar 17 and contacts the second bevel gear 20, and the second bevel gear 20 is driven to rotate through 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, so that the second moving block 21 passes The support rod 23 drives the placement plate 24 away from the solenoid valve housing. At this time, the staff rotates any horizontally distributed U-shaped frame 8, and can drive the sleeve 12 to rotate through the adjustment tube 5, so that the sleeve 12 drives the clamping plate 4 to rotate through the sliding rod 13, and the clamping plate 4 can rotate the clamped and positioned solenoid valve housing, and start the electric grinding disc 3, so that the electric grinding disc 3 grinds the outer side of the solenoid valve housing. After the grinding is completed, the staff rotates the swivel 15 counterclockwise to make the arc bar 17 drive the second bevel gear 20 to rotate and reset, and the placement plate 24 is close to the bottom of the solenoid valve housing, and the side push plate 25 on the placement plate 24 is in contact with the outer side of the solenoid valve housing, and the reaction force of the solenoid valve housing on the side push plate 25 is used to push the side push plate 25 to move, so that the side push plate 25 pushes The L-shaped slide plate 26 moves along the sliding cavity of the placement plate 24 and stretches the tension spring 27. At the same time, the L-shaped slide plate 26 drives the rack plate 31 to move synchronously, so that the rack plate 31 drives the ratchet 29 to rotate through the driven gear 30, and when the ratchet 29 stops rotating, the elasticity of the second spring 33 is used to lock the ratchet 29, and the side push plate 25 is adjusted to the corresponding position according to the size of the solenoid valve housing, so that the solenoid valve housing is in the middle position of the two placement plates 24. Subsequently, the arc bar 17 moves away from the second bevel gear 20 and contacts the first bevel gear 16, so that the two horizontally distributed clamping plates 4 move away from the solenoid valve housing. As the swivel 15 continues to rotate in the opposite 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 of the two clamping plates 4. Finally, the staff rotates any one of the two vertically distributed U-shaped frames 8 to 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, thereby achieving a comprehensive and safe grinding effect.
