[0023] Example 1: Please refer to Figure 1-6 The utility model provides a technical solution: an automated integrated tooth-cutting machine, comprising a support frame 100; a U-shaped frame 200 is installed on the top side of the support frame 100, and a lifting control structure is installed on the top side of the U-shaped frame 200, a tooth-cutting motor 300 is installed on the lifting control structure, and the tooth-cutting motor 300 is installed on the tooth-cutting structure, a fixed seat 400 is installed on the top side of the support frame 100, and a positioning structure is installed on the fixed seat 400, a cylinder bracket 500 is installed on one side of the support frame 100, and a pushing structure is installed on the cylinder bracket 500, the lifting control structure can be used to control the descent of the tooth-cutting structure and perform tooth-cutting processing on the material, and by setting the positioning structure, the position of the material can be fixed to prevent the material from shifting, and the material that has completed the tooth-cutting can be pushed out from the processing location in conjunction with the pushing structure.

[0024] Furthermore, the lifting control structure includes two supporting guide rods 201, both of which are installed on the top side of the U-shaped frame 200. The same mounting frame 202 is installed on the two supporting guide rods 201, and a downward pressure cylinder 203 is installed on the mounting frame 202. The output end of the downward pressure cylinder 203 is installed with a connecting rod 204, and a lifting frame 205 is installed on the connecting rod 204. The return motor 300 is installed on one side of the lifting frame 205, and a shell 206 is installed on the lifting frame 205. When the downward pressure cylinder 203 is started, its output end will push the connecting rod 204 to descend, and the descending connecting rod 204 will drive the lifting frame 205 to descend.

[0025] Furthermore, two guide sliding holes 207 are provided on the inner wall of the lifting frame 205, and the two support guide rods 201 are respectively slidably installed in the two guide sliding holes 207. During the descending process of the lifting frame 205, it will slide on the two support guide rods 201 respectively through the two guide sliding holes 207, limiting the lifting frame 205 to move only in the vertical direction.

[0026] Furthermore, the return gear structure includes a motor shaft 301, which is mounted on the output end of the return gear motor 300, and a transmission gear 302 is sleeved on the motor shaft 301, and a transmission belt 303 is installed on the transmission gear 302, and a transmission gear ring 304 is installed on the transmission belt 303. A rotating column 305 is sleeved on the transmission gear ring 304, and the rotating column 305 is rotatably mounted on the lifting frame 205. A die mounting assembly 306 is installed on the bottom side of the rotating column 305, and a die 307 is movably mounted on the bottom side of the die mounting assembly 306. The output end of the return gear motor 300 will drive the transmission gear 302 to rotate. When the transmission gear 302 rotates, it will drive the transmission gear ring 304 to rotate through the transmission cooperation with the transmission belt 303, so that the transmission gear ring 304 drives the rotating column 305 to rotate on the lifting frame 205, and the continuously rotating rotating column 305 will drive the die mounting assembly 306 and the die 307 to rotate.

[0027] Furthermore, multiple mounting screw holes 308 are provided on the die mounting assembly 306 and the die 307. The same screw is installed in the inner threads of the two mounting screw holes 308 on the same side. By rotating the screw in the mounting screw hole 308 and unscrewing it from the rotating column 305, the die 307 with a different thread diameter can be replaced for use.

[0028] Furthermore, the positioning structure includes a clamping cylinder 401, which is installed on the top side of the fixed base 400. Two clamping blocks 402 are provided on the clamping cylinder 401, and both clamping blocks 402 are installed with clamping claws 403. Both clamping claws 403 are located below the rotating column 305. When the clamping cylinder 401 is turned on, the clamping cylinder 401 drives the two clamping claws 403 to move and approach through the two clamping blocks 402 to clamp the material.

[0029] Example 2: Figure 1-6 In order to quickly push the processed materials away from the processing area, a pushing structure is arranged on the cylinder bracket 500. The pushing structure pushes the material cylinder 501. The pushing cylinder 501 is installed on the cylinder bracket 500. A movable frame 502 is installed on the output end of the pushing cylinder 501. The movable frame 502 is slidably installed on the top side of the support frame 100. Two positioning push blocks 503 are movably installed on one side of the movable frame 502. Adjustment holes 504 are provided on the two positioning push blocks 503. Two limiting screw holes 505 are provided on the movable frame 502. The two limiting screw holes 505 are respectively connected to the two adjustment holes. Corresponding to the node hole 504, the pushing cylinder 501 is turned on, so that the output end of the pushing cylinder 501 pushes the movable frame 502 to slide on the support frame 100, and the sliding movable frame 502 will drive the two positioning push blocks 503 to move, so that the moving positioning push blocks 503 push the workpiece back to the conveyor line for transportation. The two positioning push blocks 503 can be fixed by using bolts passing through the adjustment hole 504 and screwed into the limit screw hole 505 on the movable frame 502. After loosening the bolts, the spacing between the two positioning push blocks 503 can be adjusted according to the material size. The remaining features are the same as those in Example 1.

[0030] The working principle is as follows: when in use, the material that needs to be returned is transported to the two positioning push blocks 503 through the conveyor line, and then the pushing cylinder on the conveyor line is used to push the material between the two movable frames 502, and the two positioning push blocks 503 are used for preliminary positioning. At the same time, the material will be located between the two clamping claws 403, and then the clamping cylinder 401 is turned on, so that the clamping cylinder 401 drives the two clamping claws 403 to move and approach through the two clamping blocks 402 to clamp the material. At this time, the return motor 300 and the downward pressure cylinder 203 can be turned on, and the output end of the return motor 300 will drive the motor shaft 301 to rotate, so that the motor shaft 30 1 drives the transmission gear 302 to rotate. When the transmission gear 302 rotates, it drives the transmission ring 304 to rotate through the transmission cooperation with the transmission belt 303, so that the transmission ring 304 drives the rotating column 305 to rotate on the lifting frame 205. The continuously rotating rotating column 305 drives the die mounting assembly 306 and the die 307 to rotate. When the downward pressure cylinder 203 is started, its output end pushes the connecting rod 204 to descend. The descending connecting rod 204 drives the lifting frame 205 to descend, and then the lifting frame 205 drives the return motor 300 and the rotating column 305 to descend, so that the die mounting assembly 306 and the die 307 are connected. 307 can move downward while rotating, so that the descending and rotating die 307 is slowly sleeved on the workpiece, and the workpiece is processed. After completion, the die 307 is controlled to rise and separate from the workpiece by using the downward pressure cylinder 203. At this time, the clamping cylinder 401 can be controlled to loosen the two clamping claws 403 from the workpiece, and then the pushing cylinder 501 is turned on so that the output end of the pushing cylinder 501 pushes the movable frame 502 to slide on the support frame 100. The sliding movable frame 502 will drive the two positioning push blocks 503 to move, so that the moving positioning push blocks 503 push the workpiece back to the conveyor line for transportation, and then re-convey other The workpiece is processed in this reciprocating manner to achieve continuous back-threading processing, and the die 307 can be removed from the rotating column 305 by rotating the screw in the mounting screw hole 308 and unscrewing it from the rotating column 305, so that the die 307 with different back-threading hole diameters can be replaced for use according to the size of the material. At the same time, the two positioning push blocks 503 can be fixed by passing the bolts through the adjusting hole 504 and screwed into the limiting screw hole 505 on the movable frame 502. After loosening the bolts, the spacing between the two positioning push blocks 503 can be adjusted according to the size of the material, and the two clamping jaws 403 can also clamp materials of different sizes.
