The tray 4 is set on the operating table 1 through a connecting component.

[0022] The slide 2 is driven to move synchronously in opposite directions, and is used by the clamping plate 3 to hold the valve workpiece. The hard anti-slip rubber pad on the side wall of the clamping plate 3 ensures the stability of the valve workpiece clamping. The end of the support plate 4 is provided with a placement groove adapted to the valve workpiece.

[0023] A square hole 7 is provided on the end wall of the operating table 1. Trapezoidal blocks 8 are symmetrically connected on both sides of the square hole 7. The U-shaped lifting plate 9 in the connecting assembly is movably inserted into the square hole 7. Trapezoidal grooves 10 are symmetrically provided on both sides of the U-shaped lifting plate 9. The trapezoidal grooves 10 are movably engaged with the trapezoidal blocks 8.

[0024] The trapezoidal slide 10 and the trapezoidal block 8 are movably engaged to enable the U-shaped lifting plate 9 to move stably up and down within the square hole 7. The end of the U-shaped lifting plate 9 can block the square hole 7 to prevent debris from entering the square hole 7 during processing.

[0025] A toothed plate 11 is connected to the inner wall of the U-shaped lifting plate 9, a fixed plate 12 is connected to the side wall of the operating table 1, a rotating shaft 13 is rotatably mounted on the side wall of the square hole 7, and a handle 14 is connected to the end of the rotating shaft 13 through the side wall of the operating table 1 and the center of the fixed plate 12. A gear 15 is fixedly sleeved on the periphery of the rotating shaft 13, and the gear 15 is set in the groove of the U-shaped lifting plate 9 and meshes with the toothed plate 11.

[0026] The handle 14 can control the rotation of the shaft 13 and the gear 15. The gear 15 meshes with the toothed plate 11 to drive the U-shaped lifting plate 9 to move up and down.

[0027] A hand-tightening bolt 16 is threaded on the side wall of the handle 14, and positioning holes 17 are equidistantly arranged in a ring on the side wall of the fixed plate 12. The end of the hand-tightening bolt 16 is inserted into the positioning hole 17, and a plate groove 18 is provided on the inner end wall of the U-shaped lifting plate 9.

[0028] The end of the screw of the hand-tightening bolt 16 is inserted into the positioning hole 17 on the side wall of the fixed plate 12 to fix the position of the handle 14 and prevent the shaft 13 from rotating.

[0029] The U-shaped lifting plate 9 is inserted into the mounting frame 5. A guide post 19 is connected to the side wall of the insertion plate groove 18. An L-shaped insertion plate 20 is movably engaged in the insertion plate groove 18. The L-shaped insertion plate 20 is movably sleeved with the guide post 19. The end of the L-shaped insertion plate 20 passes through the U-shaped lifting plate 9 and is inserted into the insertion hole 6. A spring 21 is sleeved on the guide post 19.

[0030] The end of the L-shaped insert plate 20 is inserted into the insertion hole 6, which is used to fix the support plate 4 after it is installed in the U-shaped lifting plate 9. The compressed spring 21 returns to the thrust that moves the L-shaped insert plate 20 along the guide post 19.

[0031] The L-shaped insert plate 20 has a slot 22 on its side wall, and a first magnetic block 23 is fixedly embedded in the side wall of the slot 22. An L-shaped card plate 24 is rotatably mounted on the inner end wall of the U-shaped lifting plate 9, and a second magnetic block 25 is fixedly embedded in the side wall of the L-shaped card plate 24. The L-shaped card plate 24 is engaged with the slot 22, and the first magnetic block 23 and the second magnetic block 25 attract each other.

[0032] The first magnetic block 23 and the second magnetic block 25 attract each other to adsorb the L-shaped card plate 24 into the card slot 22. The inner end wall of the L-shaped card plate 24 is attached to the side wall of the L-shaped insert plate 20 to help fix the position of the L-shaped insert plate 20 and prevent the L-shaped insert plate 20 from separating from the insertion hole 6.

[0033] Working principle: Moving the L-shaped insert plate 20 along the guide post 19 compresses the spring 21, connecting the U-shaped lifting plate 9 to the mounting frame 5. Once the end of the U-shaped lifting plate 9 abuts against the bottom of the support plate 4, the L-shaped insert plate 20 is released, and the spring 21 returns to its original position, pushing the L-shaped insert plate 20 into the insertion hole 6. Then, the L-shaped locking plate 24 is rotated and engaged in the slot 22. When the first magnetic block 23 and the second magnetic block 25 attract each other, the inner wall of the L-shaped locking plate 24 adheres to the side wall of the L-shaped insert plate 20, thus limiting the L-shaped insert plate 20 and completing the connection between the support plate 4 and the U-shaped lifting plate 9. After placing the valve workpiece in the placement groove at the end of the support plate 4, the handle 14 is rotated to drive the gear 15, which rotates. 5. The meshing toothed plate 11 drives the U-shaped lifting plate 9 to move upward, raising the valve workpiece on the pallet 4 to a suitable height. Then, the screw of the hand-tightening bolt 16 is screwed into the positioning hole 17 on the side wall of the fixed plate 12 to fix the position of the handle 14, preventing the rotating shaft 13 from rotating, thereby fixing the height position of the valve workpiece. After that, the two clamping plates 3 move to clamp the valve workpiece. Unlock the handle 14 and control the U-shaped lifting plate 9 to descend and reset until the pallet 4 moves to the table surface of the operating table 1. Then, the valve workpiece can be ground. The operation is simple. The pallet 4 lifts the valve workpiece and assists the clamping plate 3 in clamping the valve workpiece. There is no need for the operator to manually support the valve workpiece. At the same time, the pallet 4 can be easily replaced to suit valve workpieces of different sizes.
