When the vertical direction needs to be adjusted, turn on the first servo motor 203. At this time, the first servo motor 203 drives the vertical screw rod 204 to rotate inside the vertical slot 202. Since the lifting block 206 is threaded on the surface of the vertical screw rod 204 and the limiting rod 205 passes through the lifting block 206, the lifting block 206 moves along the vertical screw rod 204 inside the vertical slot 202. When the water level needs to be adjusted, When the horizontal direction is flat, the second servo motor 209 is turned on. At this time, the second servo motor 209 drives the horizontal screw rod 210 to rotate inside the horizontal groove 208. Since the moving block 211 is threadedly sleeved on the surface of the horizontal screw rod 210 and embedded in the inside of the horizontal groove 208, the moving block 211 can move along the horizontal screw rod 210 inside the horizontal groove 208. When the horizontal longitudinal direction needs to be adjusted, the third servo motor 214 is turned on. At this time, the third servo motor 214 drives the longitudinal screw rod 215 to rotate inside the longitudinal groove 213. Since the slider 216 is threadedly sleeved on the surface of the longitudinal screw rod 215 and embedded in the inside of the longitudinal groove 213, the slider 216 can move along the longitudinal screw rod 215 inside the longitudinal groove 213.Thus, the workpiece can be positioned in three dimensions by controlling the first servo motor 203, the second servo motor 209 and the third servo motor 214.

[0022] Furthermore, the output end of the first servo motor 203 is connected to the vertical screw rod 204, one end of the limiting rod 205 passes through the lifting block 206, and the lifting block 206 is threadedly sleeved on the surface of the vertical screw rod 204. Through the setting of the first servo motor 203, when in use, the first servo motor 203 can drive the vertical screw rod 204 to rotate.

[0023] Furthermore, the output end of the second servo motor 209 is connected to the transverse screw rod 210, the moving block 211 is threadedly sleeved on the surface of the transverse screw rod 210, and the moving block 211 is embedded in the inside of the transverse groove 208. Through the setting of the second servo motor 209, when in use, the second servo motor 209 can drive the transverse screw rod 210 to rotate inside the transverse groove 208.

[0024] Furthermore, the output end of the third servo motor 214 is connected to the longitudinal screw rod 215, the slider 216 is threadedly sleeved on the surface of the longitudinal screw rod 215, and the slider 216 is embedded in the inside of the longitudinal groove 213. Through the setting of the third servo motor 214, when in use, the third servo motor 214 can drive the longitudinal screw rod 215 to rotate inside the longitudinal groove 213.

[0025] Furthermore, the clamping mechanism 4 includes a clamping base 401, a limiting groove 402, a driving motor 403, a rotating rod 404, a rotating arm 405, a rotating shaft 406, a connecting column 407, a limiting block 408, a clamping block 409 and a protective sheet 410. One end of the mounting base 3 is fixedly connected to the clamping base 401, a limiting groove 402 is provided on the surface of the clamping base 401, a driving motor 403 is installed on one side of the surface of the clamping base 401, an output end of the driving motor 403 is connected to the rotating rod 404, two ends of the rotating rod 404 are rotatably connected to the rotating arm 405, one end of the rotating arm 405 is penetrated by the rotating shaft 406, one end of the rotating shaft 406 is fixedly connected to the connecting column 407, one end of the connecting column 407 is connected to the limiting block 408, the other end of the connecting column 407 is connected to the clamping block 409, and the surface of the clamping block 409 is bonded and connected with the protective sheet 410. The limiting slot 402, driving motor 403, rotating rod 404, rotating arm 405, rotating shaft 406, connecting column 407, limiting block 408, clamping block 409 and protective sheet 410 are arranged. When in use, the driving motor 403 is turned on. At this time, the driving motor 403 drives the rotating rod 404 to rotate. Since the rotating arm 405 is rotationally connected to one end of the rotating rod 404, and the rotating arm 405 rotates around the connecting column 407 through the rotating shaft 406, the limiting block 408 connected to one end of the connecting column 407 is embedded in the limiting slot 402. Therefore, when the rotating rod 404 rotates, the rotating arm 405 rotates and drives the two groups of connecting columns 407 to move closer to each other along the limiting slot 402, thereby driving the two groups of clamping blocks 409 to move closer to each other. The two groups of clamping blocks 409 approaching each other can clamp and fix the workpiece, and the protective sheet 410 can protect the workpiece from being damaged by the clamping block 409.

[0026] Furthermore, the rotating arm 405 rotates around the connecting column 407 through the rotating shaft 406, and the protective sheet 410 is made of rubber. Through the setting of the protective sheet 410, the rubber protective sheet 410 can protect the workpiece and prevent the workpiece from being damaged by the clamping block 409.

[0027] Furthermore, the limiting groove 402 is a cross-shaped groove, and the limiting block 408 is a cross-shaped block. The limiting block 408 is embedded in the inside of the limiting groove 402. Through the setting of the limiting groove 402 and the limiting block 408, when in use, the limiting block 408 can play a limiting role on the connecting column 407, so that the connecting column 407 moves along the limiting groove 402 when moving.

[0028] Working principle: Turn on the driving motor 403, at this time the driving motor 403 drives the rotating rod 404 to rotate. Since the rotating arm 405 is rotationally connected to one end of the rotating rod 404, and the rotating arm 405 rotates around the connecting column 407 through the rotating shaft 406, at the same time, the limiting block 408 connected to one end of the connecting column 407 is embedded in the limiting groove 402. Therefore, when the rotating rod 404 rotates, the rotating arm 405 rotates and drives the two sets of connecting columns 407 to move closer to each other along the limiting groove 402, thereby driving the two sets of clamping blocks 409 to move closer to each other. The two sets of clamping blocks 409 approaching each other can clamp and fix the workpiece, and at the same time, the protective sheet 410 can protect the workpiece from being damaged by the clamping blocks 409. When the vertical direction needs to be adjusted, turn on the first servo motor 203. At this time, the first servo motor 203 drives the vertical screw rod 204 to rotate inside the vertical groove 202. Since the lifting block 206 is threaded on the surface of the vertical screw rod 204 and the limiting rod 205 passes through the lifting block 206, The lifting block 206 moves along the vertical screw rod 204 inside the vertical slot 202. When the horizontal transverse direction needs to be adjusted, the second servo motor 209 is turned on. At this time, the second servo motor 209 drives the transverse screw rod 210 to rotate inside the transverse slot 208. Since the moving block 211 is threadedly sleeved on the surface of the transverse screw rod 210 and embedded in the transverse slot 208, the moving block 211 can move along the transverse screw rod 210 inside the transverse slot 208. When the horizontal longitudinal direction needs to be adjusted, the third servo motor 214 is turned on. At this time, the third servo motor 214 drives the longitudinal screw rod 215 to rotate inside the longitudinal slot 213. Since the slider 216 is threadedly sleeved on the surface of the longitudinal screw rod 215 and embedded in the longitudinal slot 213, the slider 216 can move along the longitudinal screw rod 215 inside the longitudinal slot 213. Therefore, the workpiece can be three-dimensionally positioned by controlling the first servo motor 203, the second servo motor 209 and the third servo motor 214.
