[0027] Working principle: Before using the cutting tool 304 for processing, select a suitable tool according to the workpiece to be processed, and replace the tool after selecting it. When replacing the tool, insert the external pin into the two blind holes of the rotating block 305 located at the outer end of the tool fixing handle 303, and rotate the rotating block 305 clockwise. At this time, the locking shaft 306 will be driven to rotate clockwise, and the locking shaft 306 will rotate clockwise inside the tool fixing handle 303. At this time, the locking shaft 306 will drive the two internal protruding blocks 308 to rotate, and the arc-shaped surfaces of the two protruding blocks 308 will move toward the inside of the locking shaft 306 according to the groove inside the tool fixing handle 303, and squeeze the reset spring 310.

[0028] When the rotating block 305 is inserted into the tool fixing handle 303, the left end of the rotating block 305 will drive the matching shaft 309 slidably connected to the outer surface to rotate, and at the same time, the right end of the rotating block 305 will drive the locking shaft 306 to rotate, while the middle part of the rotating block 305 does not move under the limit of the matching block 307. At this time, the middle part of the rotating block 305 and the two ends of the rotating block 305 are misaligned. At this time, the protruding block 308 inside the locking shaft 306 is displaced into the groove inside the tool fixing handle 303 under the action of the reset spring 310, so that the rotating block 305 can be fixed. The tool 304 is locked in the tool fixing handle 303, so that the cutting tool 304 is fixed inside the tool fixing handle 303. When the cutting tool 304 needs to be replaced, the rotating block 305 is inserted into the two blind holes at one end of the outer side of the tool fixing handle 303 through the external pin, and the rotating block 305 is rotated counterclockwise to align the left end, the right end and the middle of the rotating block 305. At this time, the protruding block 308 inside the locking shaft 306 slides out of the groove inside the tool fixing handle 303, and the restriction on the cutting tool 304 can be released by pulling the rotating block 305 outward.

[0029] After the cutting tool 304 is replaced, the tool fixing handle 303 is installed inside the clamping sleeve 302. At this time, the hand wheel 401 is rotated counterclockwise, thereby driving the locking shaft 403 to rotate counterclockwise. One end of the locking shaft 403 located inside the moving box 201 drives the second active bevel gear 404 to rotate counterclockwise, and drives the second driven bevel gears 405 on both sides to rotate through meshing. At this time, the rotating sleeve 406 rotates, thereby driving the two sliding blocks fixed on the outer side of one end of the moving rod 407 to move closer to the second driven bevel gear 405, thereby driving the moving rod 407 and the moving block 408 to move, and the clamping plate 410 at the lower end of the moving block 408 will also approach the tool fixing handle 303. When the clamping plate 410 is against the groove on the tool fixing handle 303, the handle on the hand wheel 401 is pushed towards the groove on the surface of the locking plate 402, so that the hand wheel 401 is locked, thereby realizing that the tool fixing handle 303 is fixed inside the clamping sleeve 302.

[0030] After fixing the tool fixing handle 303, the hydraulic telescopic rod 204 is adjusted by controlling the control box 5, thereby driving the square slider 203 to slide along the slide groove on the side of the support box 202, thereby realizing the vertical displacement of the mobile box 201 and the displacement of the tool fixing mechanism 3.

[0031] After the tool fixing mechanism 3 is moved to a suitable position, the third motor 301 is started through the control box 5. At this time, the third motor 301 drives the clamping sleeve 302 to rotate, and the clamping sleeve 302 drives the tool fixing handle 303 to rotate through the rotating block 305, thereby realizing the rotation of the cutting tool 304 and realizing the cutting of the surface of the workpiece by the cutting tool 304.

[0032] During cutting, the workpiece is fixed on the three-claw disk 102. When it needs to be moved, the first motor 106 is started through the control box 5. The output end of the first motor 106 drives the active gear 107 to rotate, thereby driving the moving rack 108 to move horizontally along the fixed slide groove 109. At this time, the moving rack 108 drives the moving guide rail 103 to move forward and backward along the slide groove on the outer shell 1 through the connection of the fixed block, thereby driving the three-claw disk 102 at the upper end to move forward and backward, realizing the displacement of the workpiece in the front and rear directions.

[0033] The second motor 110 is started through the control box 5, thereby driving the driving shaft 111 to rotate, and then driving the first driving bevel gear 113 at the end of the driving shaft 111 to rotate, the first driving bevel gear 113 drives the first driven bevel gear 114 to rotate, and the first driven bevel gear 114 drives the driven gear 116 to rotate under the action of the rotating shaft 115, thereby driving the fixed rack 117 to move in the left and right directions, thereby driving the three-claw disk 102 to move in the left and right directions, and realizing the left and right direction displacement of the workpiece.

[0034] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
