Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 3 This invention discloses a grinding device for the internal sealing surface of a valve body, comprising:

[0033] Box 1;

[0034] Valve plate inclined support 10, the top of valve plate inclined support 10 is inclined, valve plate 12 is fixed on the inclined surface of valve plate inclined support 10, the inclined surface of valve plate inclined support 10 contacts the inclined end of valve plate 12 so that the flat end of valve plate 12 is horizontal.

[0035] The rotating part and the fixed end are horizontally movable inside the housing 1. The rotating end of the rotating part is axially connected to the bottom of the valve plate inclined support 10 to drive the valve plate inclined support 10 to rotate.

[0036] The grinding assembly is vertically and movably installed inside the housing 1.

[0037] In use, the inclined end of the valve plate 12 is brought into contact with the inclined surface of the valve plate inclined support 10 and fixed on the valve plate inclined support 10. The valve plate inclined support 10 can be driven by the rotating part to drive the valve plate 12 to rotate. When the rotating part moves to the bottom of the grinding assembly, the grinding assembly descends so that the grinding end contacts the end face of the valve plate 12, realizing functions such as cutting, grinding, and polishing. Compared with traditional equipment, this device can grind and cut valve plates 12 with one end being inclined and the other end being flat.

[0038] As an optional implementation, the valve plate inclined support 10 includes an inclined support body 1001, the top of which is an inclined surface that matches the angle of the inclined end of the valve plate 12.

[0039] The bottom of the inclined support body 1001 is axially connected to the rotating end of the rotating part;

[0040] The inclined support body 1001 has a slot 1002 in the middle;

[0041] The slot 1002 is provided with a clamping part for fixing the valve plate 12.

[0042] As an optional implementation, the clamping part includes two symmetrically arranged clamps 11, which are distributed on both sides of the valve plate 12. The clamps 11 are slidably disposed in the slot 1002 and are fixed to the slot 1002 by set screws.

[0043] As an optional implementation, a horizontally arranged sliding groove 1003 is provided in the slot 1002. The sliding groove 1003 and the gripper 11 are horizontally slidably arranged, and the gripper 11 and the sliding groove 1003 are vertically limited and engaged.

[0044] The clamping part consists of two grippers 11, which are horizontally slidably disposed in the slot 1002. A sliding groove 1003 is provided on the side wall of the slot 1002. The protrusions at the bottom of the grippers 11 extend into the sliding groove 1003, so that the grippers 11 and the sliding groove 1003 slide horizontally and are vertically limited.

[0045] In use, the two grippers 11 hold the valve plate 12 in the middle, and the set screws are used to fix the grippers 11 to the bottom of the slot 1002, thereby fixing the valve plate 12 to the inclined support body 1001.

[0046] As an optional implementation, the rotating part includes a turntable 9, the movable end of which is axially connected to the bottom of the inclined support body 1001, and the fixed end of the turntable 9 is fixedly connected to the translation box 8, which is horizontally slidably disposed in the box body 1.

[0047] After the valve plate 12 is coaxially mounted on the inclined support body 1001, the inclined support body 1001 can be driven to rotate by the turntable 9, so that the valve plate 12 can rotate and cooperate with the grinding assembly to achieve grinding and polishing processes.

[0048] As an optional implementation, the translation box 8 is fixed to the moving end of the translation module 7, and the fixed end of the translation module 7 is fixed to the bottom of the box body 1.

[0049] By setting up the translation module 7, the inclined support body 1001 can be moved closer to or further away from the grinding component.

[0050] The translation module 7 is preferably a linear motor.

[0051] As an optional implementation, the grinding assembly includes a protective box 3, which contains a cutting part for cutting the end face of the valve plate 12 and a grinding part for grinding the end face of the valve plate 12.

[0052] The protective box 3 is fixedly connected to the lifting end of the lifting module 2, and the fixed end of the lifting module 2 is fixedly connected to the side wall of the box 1.

[0053] The lifting module 2 can drive the protective box 3 to rise and fall. After the valve plate 12 is moved into position, the lifting module 2 lowers the protective box 3, thereby making the grinding part or cutting part contact the end face of the valve plate 12.

[0054] The lifting module 2 is preferably a linear motor.

[0055] As an optional implementation, the grinding section includes a grinding wheel 5, the shaft of which is connected to the movable end of a motor 6, and the fixed end of the motor 6 is fixed inside the protective housing 3.

[0056] The end face of the valve plate 12 is ground by the rotation of the valve plate 12 and the rotation of the grinding wheel 5 driven by the motor 6.

[0057] As an optional implementation, the cutting part includes a cutter head 4, which is fixedly attached to the protective housing 3.

[0058] The end face of the valve plate 12 contacts the cutter head 4. The cutter head 4 is raised and lowered by the lifting module 2, which can realize the processing of the end face of the valve plate 12.

[0059] As an optional implementation, a hatch is provided on the front side of the container 1.

[0060] Example 2:

[0061] The difference between this embodiment and embodiment 1 is that the bottom threads of the two grippers 11 are threaded onto the two ends of the bidirectional threaded rod. The bidirectional threaded rod is used to drive the two grippers 11 to move closer or further apart. The bidirectional threaded rod is rotatably mounted in the inclined support body 1001, and a servo motor is axially connected to either end of the bidirectional threaded rod.

[0062] By driving the bidirectional threaded rod to rotate via a servo motor, the two grippers 11 can be driven to move closer or further apart to clamp and release the valve plate 12. Since the two grippers 11 can move simultaneously, the valve plate 12 can be directly coaxial with the inclined support body 1001 when it is clamped, which can improve work efficiency.
