[0025] The lower part of rotating shaft 5 is fixedly sleeved with worm wheel 15, one side of worm wheel 15 is meshingly connected with worm 16, worm 16 is rotatably connected with the inner wall of base 1, one end of worm 16 extends to the outside of base 1 and is connected with handle 17.

[0026] The clamping assembly 13 includes a mounting rod 1301, which is inclined on both sides. The upper ends of the mounting rod 1301 are rotatably connected to a middle connecting rod 1302 via pins. The lower ends of the middle connecting rod 1302 are rotatably connected to a front connecting rod 1303 and a rear connecting rod 1304 via pins. One end of the front connecting rods 1303 on both sides is rotatably connected to the same L-shaped plate 1305 via pins. One end of the L-shaped plate 1305 is detachably connected to a clamping block 1307 via bolts 1306. The detachable structure of the clamping block 1307 via bolts 1306 facilitates the replacement of clamping block 1307 structures corresponding to different models of valve workpieces. The rear connecting rods 1304 on both sides are rotatably connected to a mounting plate 1308 via pins. The mounting plate 1308 is fixed to the upper end of the top plate 9.

[0027] Guide blocks 1309 are connected to the upper ends of the mounting plates 1308 on both sides. Guide posts 1310 are slidably connected inside the guide blocks 1309. One end of the guide posts 1310 on both sides is connected to the L-shaped plate 1305.

[0028] The adjustable clamping component 14 includes a connecting block 1401, with a threaded hole running through the interior of the connecting block 1401. An adjusting screw 1402 is threadedly connected inside the threaded hole. One end of the adjusting screw 1402 is rotatably connected to a retaining block 1403. A locking nut 1404 is threadedly fitted onto the outer side of the adjusting screw 1402 to limit its rotation after adjustment and prevent the adjusting screw 1402 from accidentally rotating.

[0029] The cross-section of the slide groove 3 is set in an inverted T-shape, and the slider 4 is adapted to the slide groove 3 to ensure the stability of operation.

[0030] Working principle:

[0031] Place the valve workpiece on the top plate 9, and the operator rotates the handle 17. The handle 17 drives the worm gear 16 to rotate on the inner wall of the base 1.

[0032] The rotation of the worm 16 is transmitted to the worm wheel 15 through a meshing relationship, causing the worm wheel 15 to drive the rotating shaft 5 to rotate; the rotation of the rotating shaft 5 drives the disk 6 to rotate. Since one end of the arc plate 8 is rotatably connected to the annular groove 7 on the disk 6 through a pin, and the other end is rotatably connected to the slider 4 through a pin, when the disk 6 rotates, the arc plate 8 is subjected to a traction force and rotates around the pin.

[0033] The rotation of the arc plate 8 causes the slider 4 to slide in the groove 3. Since the groove 3 has an inverted T-shaped cross section that matches the slider 4, the slider 4 remains stable during the sliding process.

[0034] As the slider 4 slides, the connecting post 11 moves accordingly and remains within the corresponding waist-shaped groove 10;

[0035] The design of the waist-shaped groove 10 allows the connecting column 11 to move within a certain range, thereby achieving adjustment of the clamping position;

[0036] When the connecting column 11 moves, the fixed block 12 moves accordingly, thereby driving the clamping assembly 13 and the adjustable clamping piece 14 to move;

[0037] The clamping assembly 13 pushes the L-shaped plate 1305 and the clamping block 1307 towards the valve workpiece through the connecting rod mechanism (middle connecting rod 1302, front connecting rod 1303, and rear connecting rod 1304), thereby achieving clamping. The guide column 1310 moves inside the guide block 1309, thereby ensuring the stability of the L-shaped plate 1305 when driving the clamping block 1307 to move;

[0038] The adjustable clamping piece 14 adjusts the position of the abutting block 1403 through the rotating adjustment screw 1402, thereby achieving abutting clamping from the other two sides, so as to adapt to the clamping requirements of valve workpieces of different specifications;

[0039] After the valve workpiece is stably clamped by the clamping assembly 13 and the adjustable clamping piece 14, the device can perform subsequent machining operations.
