[0030] Example 1:

[0031] A kind of internal grinding device for processing bellows control valves, including a support tabletop 1. On the left side of the top of the support tabletop 1, a left support plate 2 is fixedly connected. On the right side of the top of the support tabletop 1, a right support plate 9 is fixedly connected. Inside the top of the left support plate 2, a plurality of connecting rods 4 are fixedly connected. Inside the lower part of the left support plate 2, a lower traction column 6 is slidably connected. At the top of the lower traction column 6, a lower rubber pad 7 is fixedly connected. Inside the upper part of the left support plate 2, an upper traction column 3 is slidably connected. At the bottom of the upper traction column 3, an upper rubber pad 14 is fixedly connected. Inside the lower traction column 6, a lower push plate 20 is slidably connected. Abrasive 18 is filled at the top of the lower push plate 20. Inside the upper traction column 3, an upper push block 21 is slidably connected. A grinding drive assembly is installed inside the right support plate 9, and an adjustment and fixation assembly is installed inside the left support plate 2. The grinding drive assembly includes a one-way threaded rod 17 located inside the right support plate 9. An external thread of the one-way threaded rod 17 is threadedly connected with a traction block 8. Inside the traction block 8, a traction frame 10 is fixedly connected. Inside the lower part of the traction frame 10, a lower electric push rod 19 is fixedly connected. Inside the upper part of the traction frame 10, an upper electric push rod 16 is fixedly connected. On the top of the right support plate 9, a second motor 11 is fixedly connected. The driving end of the second motor 11 is fixedly connected to the top of the one-way threaded rod 17. The outside of the traction block 8 is slidably connected inside the right support plate 9. The output end of the lower electric push rod 19 is fixedly connected to the bottom of the lower push plate 20. The output end of the upper electric push rod 16 is fixedly connected to the top of the upper push block 21;

[0032] After the valve seat is fixed, the upper electric push rod 16 and the lower electric push rod 19 are started simultaneously. The lower electric push rod 19 pushes the lower push plate 20 upward, thereby pushing the abrasive 18 upward, so that it enters the inside of the valve body. And the abrasive 18 passes through the inside of the valve body and contacts the lower side of the upper push block 21, thereby extruding the abrasive 18. At this time, the second motor 11 is started to rotate the one-way threaded rod 17. The external thread of the one-way threaded rod 17 contacts the traction block 8, thereby moving the traction block 8 downward, and driving the traction frame 10 to move. Through the movement of the traction frame 10, the abrasive 18 grinds inside the valve body. The abrasive 18 fits more closely to the inside of the valve body, completing the grinding work, making the internal grinding of the device more fitting, thereby further improving the grinding effect on the inside of the valve body and being more convenient.

[0033] Embodiment 2: The adjusting and fixing assembly includes a bidirectional threaded rod 13 located inside the left support plate 2. A lower moving block 12 is threadedly connected to the lower side of the outer part of the bidirectional threaded rod 13, and an upper moving block 15 is threadedly connected to the upper side of the outer part of the bidirectional threaded rod 13. A first motor 5 is fixedly connected to the middle of the top end of the left support plate 2, and the driving end of the first motor 5 is fixedly connected to the top end of the bidirectional threaded rod 13. The outer part of the upper moving block 15 is slidably connected to the upper side inside the left support plate 2, and the inner side of the upper moving block 15 is fixedly connected to the outer side of the upper traction column 3. The outer part of the lower moving block 12 is slidably connected to the lower side inside the left support plate 2, and the inner side of the lower moving block 12 is fixedly connected to the outer side of the lower traction column 6;

[0034] When grinding the valve seat, place the bottom of one side of the valve seat on the top end of the lower rubber pad 7. At this time, start the first motor 5 to drive the bidirectional threaded rod 13 to rotate. As the external threads of the bidirectional threaded rod 13 come into contact with the internal threads of the lower moving block 12 and the upper moving block 15 respectively, the upper traction column 3 and the lower traction column 6 are brought into contact with each other simultaneously. When the bottom of the upper rubber pad 14 touches the top of the valve body, the valve seat is fixed by the extrusion of the upper traction column 3 and the lower traction column 6. Valves of different lengths can be stably fixed, so as to grind valve seats of different sizes more stably.

[0035] Working principle: When grinding the valve seat, place the bottom of one side of the valve seat on the top end of the lower rubber pad 7. At this time, start the first motor 5 to drive the bidirectional threaded rod 13 to rotate, so that the upper traction column 3 and the lower traction column 6 are brought into contact with each other simultaneously. When the bottom of the upper rubber pad 14 touches the top of the valve body, the valve seat is fixed by the extrusion of the upper traction column 3 and the lower traction column 6. After the valve seat is fixed, start the upper electric push rod 16 and the lower electric push rod 19 simultaneously. The lower electric push rod 19 pushes the lower push plate 20 upward, thereby pushing the abrasive 18 upward, so that it enters the inside of the valve body. And the abrasive 18 passes through the inside of the valve body and touches the lower side of the upper push block 21, thereby extruding the abrasive 18. At this time, start the second motor 11 to rotate the unidirectional threaded rod 17, thereby moving the traction block 8 downward, and driving the traction frame 10 to move. By the movement of the traction frame 10, the abrasive 18 grinds inside the valve body, and the abrasive 18 fits more closely to the inside of the valve body to complete the grinding work.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
