Abstract
Description
Technical Field

[0002] As a core component of industrial piping systems that controls fluid flow, regulates flow and pressure, and other key functions, the machining accuracy of the valve's internal structure directly affects the sealing performance and service life.
[0003] When it comes to grinding the inner cavity of a valve, traditional devices are prone to eccentricity problems during positioning. When the valve placement position does not coincide with the center position of the grinding device, the grinding head and motor shaft will be subjected to uneven forces during the grinding process, which not only affects the grinding effect, but also easily causes damage to the grinding head and motor shaft, increasing the maintenance cost of the equipment and production downtime. For valves with multiple inner cavities, after completing the grinding of one inner cavity, the valve needs to be manually replaced in order to process another inner cavity. This manual secondary replacement method not only consumes a lot of manpower and time, reducing production efficiency, but also may affect the overall processing accuracy of the valve due to problems such as inaccurate positioning during the replacement process.

[0013] The present invention provides an inner cavity processing device for valve processing through improvement. Compared with the prior art, it has the following improvements and advantages:
[0014] First: By setting a grinding device in the present invention, the valve is placed on the grinding platform. By rotating the rotary adjustment rod, the second gear is driven to rotate, and then the first gear is driven to rotate to adjust the extended length of the telescopic rod until the grinding head presses against the inner wall of the valve. The electric switch is pressed under the valve to drive the electric telescopic rod to push the valve forward until the inner cavity of the valve and the output shaft of the motor are in the same position. At this time, grinding is carried out, and the grinding head and the motor shaft will not be damaged due to eccentricity problems.
[0015] Second: By setting a valve flipping and redirecting device in the present invention, when one inner cavity of the valve is ground, the second motor is started to drive the first cross bar to rotate, and then through the cooperation of the third gear and the fourth gear, the valve fixture is flipped.

The center of the other inner cavity of the valve can be aligned with the grinding device, and then the other inner cavity is ground, reducing the time for manual secondary replacement of the valve, and the size of the grinding device is adjustable and still grinds at the center.
[0016] Third: By setting a conductive device in the present invention, during the grinding process, the vertical rod rotates at a high speed. Under the action of centrifugal force, the energizing block stretches the spring and presses against the outer side wall of the outer through groove. At this time, the connection between the energizing block and the electromagnetic ball is released, so that the second motor is not energized. When the grinding is completed, the energizing block returns to directly below the electromagnetic ball under the contraction force of the reset spring and contacts the electromagnetic ball. At this time, it is energized and drives the second motor to work. Through the cooperation of the conductive device, grinding and valve flipping can be highly coordinated, saving operation time.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0026] The present invention provides an internal cavity processing device for valve processing by improvement. The technical solution of the present invention is:
[0027] As Figure 1 - Figure 5As shown in the figure, an inner cavity processing device for valve machining includes a workbench 1. A valve positioning groove 2 is formed in the inner wall of the workbench 1. A hydraulic press 3 is fixedly connected to the upper surface of the workbench 1. A worm 4 is rotatably connected to the lower surface of the hydraulic press 3. A lifting block 5 is threadedly connected to the surface of the worm 4. A first motor 6 is fixedly connected to the front side wall of the lifting block 5. An output end of the first motor 6 is fixedly connected to a vertical rod 7. A grinding device is fixedly connected to the lower end of the vertical rod 7. A conductive device is fixedly connected to the surface of the vertical rod 7. A valve turning and reversing device is arranged inside the workbench 1.
[0028] Furthermore, the grinding device includes a first gear 8. The upper end of the first gear 8 is fixedly connected to the lower end of the vertical rod 7. A plurality of first chutes 9 penetrating through the lower end are formed in the upper end of the first gear 8. A plurality of first positioning blocks 10 are fixedly connected to the lower end of the first gear 8. Second chutes 43 are formed in the interiors of the plurality of first positioning blocks 10. Spring groups 11 are fixedly connected to the inner walls of the second chutes 43. The other ends of the spring groups 11 are fixedly connected to telescopic rods 12. Moving cylinders 13 are fixedly connected to the upper surfaces of the telescopic rods 12. Grinding blocks 14 are fixedly connected to the front side walls of the telescopic rods 12. A second gear 15 is meshed with the surface of the first gear 8. A rotary adjusting rod 16 is fixedly connected to the upper end of the second gear 15. A ratchet 17 is fixedly connected to the surface of the rotary adjusting rod 16. A protective cover 42 is rotatably connected to the lower end of the ratchet 17. A pawl adjusting cylinder 18 is fixedly connected to the upper end of the protective cover 42. A pawl sliding block 19 is slidably connected to the surface of the pawl adjusting cylinder 18. A pawl 20 is fixedly connected to the upper end of the pawl sliding block 19. During the high-speed rotation of the grinding device, the grinding block 14 is stretched outward by the centrifugal force to stretch the spring group 11. At this time, the buffer effect can be achieved through the arranged spring group 11, greatly reducing the damage of the telescopic rod 12 under the action of the centrifugal force.
[0029] Furthermore, the conductive device includes a fixing plate 32. The upper surface of the fixing plate 32 is fixedly connected to the surface of the vertical rod 7. A conductive block 33 is fixedly connected to the inner wall of the fixing plate 32. A fixing block 34 is fixedly connected to the surface of the vertical rod 7. Symmetric square grooves 36 are formed in the surface of the fixing block 34. Two through grooves 37 communicating with the square grooves 36 are formed in the interior of the fixing block 34. Symmetric storage batteries 35 are fixedly connected to the lower surface of the fixing block 34. Spherical grooves 38 are formed in the inner walls of the square grooves 36.

By arranging the reset springs 40, when the vertical rod 7 stops rotating, the reset of the reset springs 40 can drive the power-on blocks 41 to return to their original positions.
[0030] Further, the valve turning device includes a second motor 21. The rear side wall of the second motor 21 is fixedly connected to the inner wall of the workbench 1. The output end of the second motor 21 is rotatably connected to a first cross bar 22. The front end of the first cross bar 22 is fixedly connected to a third gear 23. The third gear 23 is meshed with a fourth gear 24. The front end of the fourth gear 24 is fixedly connected to a second cross bar 25. The front end of the second cross bar 25 is fixedly connected to a valve clamp 26. The surface of the valve clamp 26 is fixedly connected to a clamp support block 27. The front end of the clamp support block 27 is fixedly connected to a third cross bar 28. The front end of the third cross bar 28 is rotatably connected to the inner wall of the workbench 1. The number of teeth of the third gear 23 is only one-fourth of the number of teeth of the fourth gear 24. Through this setting, the valve clamp 26 can be turned 90 degrees under the cooperation of the third gear 23 and the fourth gear 24.
[0031] Further, the upper end of the wire 44 is fixedly connected to the lower surface of the conductive block 33. The conductive block 33 is connected to the second motor 21 through an electric wire. An energized block 41 is arranged directly below the electromagnetic ball 39. Through the cooperation of the electromagnetic ball 39 and the energized block 41, the grinding intermittent time can be reduced and the work efficiency can be improved.
[0032] Further, the surface of the pawl 20 is meshed with the surface of the ratchet wheel 17. By arranging the ratchet wheel 17 and the pawl 20, when the rotation adjusting rod 16 rotates to a suitable position, a limiting effect can be achieved.
[0033] Further, an electric telescopic rod 29 is fixedly connected to the inner wall of the valve clamp 26. The front end of the electric telescopic rod 29 is fixedly connected to a valve positioning bracket 30. An electric switch 31 is fixedly connected to the inner wall of the valve clamp 26. By arranging the electric telescopic rod 29, the inner cavity of the valve and the grinding device can be on the same center line, preventing the output shaft of the first motor 6 from being in an eccentric state.
[0034] Further, the side wall of the telescopic rod 12 is slidably connected to the inner wall of the second chute 43. The surface of the moving cylinder 13 is slidably connected to the inner wall of the first chute 9. By arranging the moving cylinder 13, when the first gear 8 is rotated, the moving cylinder 13 displaces in the first chute 9 to adjust the size of the grinding device to adapt to the grinding of inner cavities of different sizes.
[0035] Working principle: Place the valve to be polished on the workbench 1. At this time, the gravity of the valve presses the electric switch 31, starting the first chute 9 to push forward. The valve positioning bracket 30 abuts against the valve. Rotate the ratchet wheel 17. Through the cooperation of the second gear 15, drive the first gear 8 to rotate, drive the moving cylinder 13 to slide in the first chute 9, so that the telescopic rod 12 extends outwards until the grinding block 14 presses against the inner wall of the valve. At this time, start the hydraulic press 3 and the first motor 6. Driven by the vertical rod 7, the grinding device rotates at high speed to grind the inner cavity of the valve. During the grinding process, the energizing block 41 disconnects from the electromagnetic ball 39 under the action of centrifugal force. When the grinding is completed and the vertical rod 7 stops rotating, the energizing block 41 moves to the directly below of the electromagnetic ball 39 and is connected under the action of the return spring 40. At this time, start the second motor 21 through the action of the conductive wire 44 and the conductive block 33. The output end of the second motor 21 drives the first cross bar 22 to rotate. Through the cooperation of the third gear 23 and the fourth gear 24, the valve fixture 26 rotates 90 degrees. The valve releases the restriction on the electric switch 31 due to the rotation, closes the electric switch 31 to retract the electric telescopic rod 29. At this time, adjust the grinding device according to the above steps to grind this inner cavity again.
