[0068] Working principle:

[0069] The present application significantly improves the adaptability and flexibility of the device by processing the gear in two different ways of straight teeth and helical teeth, which can meet the needs of various gear machining. Compared with the traditional single machining method, the present application does not need to purchase multiple machining devices, greatly reduces the equipment procurement and maintenance cost, and simplifies the production process. In addition, the present application also integrates the deburring function, which can automatically deburr the gear after machining, improves the surface quality and precision of the gear, reduces the subsequent machining steps, and further improves the production efficiency.

[0070] Another advantage of the present application is that it can adapt to gears of different sizes, ensuring the stability and precision of the gear during machining, avoiding the problems of unstable fixation or machining error caused by different gear sizes in traditional machining;

[0071] When it is needed to install the unprocessed gear to the cylindrical shaft 208, first, one sleeve 207 on one side is separated from the cylindrical shaft 208, two large cams 202 are driven to rotate by two motors on the external support 101, at this moment, the rotating directions of the two large cams 202 are opposite, the two large cams 202 clamp the cylindrical shaft 208, the belt and the pulley are driven to rotate by the second motor 203, then the two large cams 202 are driven to rotate, the short rod 204 drives the second screw rod combination mechanism 205 to move, then the third motor 206 and the sleeve 207 move away from one side of the cylindrical shaft 208, then the unprocessed gear is sleeved on the appropriate cylindrical hollow cylinder 209, if the size of the unprocessed gear is consistent with the size of the cylindrical hollow cylinder 209 in the middle position, according to which side of the third motor 206 and the sleeve 207 moves away, the large cam 202 close to this side is selected to rotate to support the cylindrical shaft 208 below, and the large cam 202 far away returns to the original position;

[0072] When the gear to be processed is sleeved on the cylindrical hollow cylinder 209, the cylindrical gear 213 is driven to rotate by the fourth motor 212, then the pushing disc 214 is driven to rotate, the arc-shaped protruding block on the pushing disc 214 pushes the L-shaped rod 215 in the corresponding position to move, the five L-shaped rods 215 extend out of the inside of the cylindrical hollow cylinder 209, then the two sliding discs 211 are driven to move inwards by the two third screw rod combination mechanisms 210, then the two groups of L-shaped rods 215 on the two sides extrude the gear to be processed, so that the gear does not deviate during processing, and the processing effect is ensured;

[0073] When the gear is processed by straight teeth, the motor on the square plate 104 drives the swing groove plate 105 to swing, then the connecting support frame 106, the first motor 107 and the gear milling cutter 108 move, the connecting support frame 106 is limited by the limiting cylindrical rod 109 and can only move forward and backward, when the gear milling cutter 108 moves close to the unprocessed gear, the gear milling cutter 108 is driven to rotate by the first motor 107, then the gear milling cutter 108 cuts the unprocessed gear, the gear milling cutter 108 cuts a row of teeth on the unprocessed gear, at the same time, the third motor 206 drives the sleeve 207 to rotate the cylindrical shaft 208, then the gear on the cylindrical hollow cylinder 209 rotates slowly, so that the gear milling cutter 108 processes a row of regular teeth on the side of the gear;

[0074] In order to facilitate the straight tooth processing of different gears, the first screw rod combination mechanism 103 drives the square plate 104 to move, then other parts on the square plate 104 move, then the gear milling cutter 108 moves, so that the gear milling cutter 108 moves to the side of different gears, and the processing is facilitated;

[0075] The third motor 206, the sleeve 207 and the cylindrical shaft 208 are driven to descend by the second screw rod combination mechanism 205, and then the cylindrical hollow cylinder 209 and the gear outside the cylindrical hollow cylinder 209 are driven to descend, and after the gear is descended to the appropriate position;

[0076] When the helical tooth processing is performed on the unprocessed gear, the hobbing gear 303 is driven to ascend by the first electric cylinder 304, so that the hobbing gear 303 is close to the outside of the unprocessed gear, and then the motor on the hobbing gear 303 rack drives the hobbing gear 303 to rotate, while the third motor 206 drives the sleeve 207 and the cylindrical shaft 208 to rotate, and then drives the cylindrical hollow cylinder 209 and the gear on the cylindrical hollow cylinder 209 to rotate, so that the gear is processed by helical tooth; because the gears on the cylindrical hollow cylinder 209 are of different sizes, the first electric cylinder 304 is extended and retracted to enable the hobbing gear 303 to better fit each gear, improve the equipment adaptability, and the rectangular plate 302, the hobbing gear 303 and the first electric cylinder 304 are moved to the lower side of different gears by the fourth screw rod combination mechanism 301, improving the processing efficiency;

[0077] The double-elliptical cam 306 is driven to rotate by the motor on the supporting bottom plate 305, and then the connecting rod 307 is swung, so that the connecting support rod 308 is moved, and then the two arc-shaped polishing plates 309 are moved inward, so that the two arc-shaped polishing plates 309 clamp the gear, and then the sleeve 207 is driven to rotate by the third motor 206, so that the cylindrical shaft 208 is driven to rotate, and then the cylindrical hollow cylinder 209 and the gear on the cylindrical hollow cylinder 209 and the processed gear are driven to rotate, so that the arc-shaped polishing plate 309 polishes the burrs on the outside of the gear; in order to process different gears, the second electric cylinder 310 is extended and retracted to drive the rectangular block on the second electric cylinder 310 extension rod to extend into the through square hole of the fourth screw rod combination mechanism 301, and then the slider is moved by the fourth screw rod combination mechanism 301, so that the second electric cylinder 310 is moved, and then the supporting bottom plate 305 is moved, so that the arc-shaped polishing plate 309 is moved to the side surface of different gears, facilitating polishing.
