As people's knowledge of mechanical structure continues to deepen, the car was born. The birth of the car enables people to go farther and save time. As the functions of the car continue to improve, the car clutch was also invented.

[0003] The meshing sleeve is an important component in the automobile transmission system, mainly used in non-synchronous transmission; its function is to realize the conversion of transmission force and speed between two gears; when the two gears transmit force, the meshing sleeve is needed to make them mesh normally and eliminate the impact force and sound generated in the transmission;

[0004] However, the meshing sleeve is currently made by manually placing the meshing sleeve on a machine tool, and then manually placing different cutter heads in fixed positions, and then grinding the meshing sleeve.

[0069] Working principle:

[0070] The meshing sleeve is manually placed at the circular hole position of the clamping meshing sleeve part 2, and the cam I 202 is driven to rotate by the motor on the fixed frame 201, so that the cam I 202 pushes the sliding frame 203 to move forward, and the cylindrical rod 204 is driven to move forward by the sliding frame 203, and the spur rack II 214 is driven to move, thereby driving the cylindrical gear III 215 to rotate, further driving the bevel gear 216 to rotate, thereby driving the bevel gear on the shaft of the cylindrical gear IV 217 to rotate, and then driving the cylindrical gear IV 217 to rotate, thereby driving the large gear 218 to rotate, and further moving the slide groove on the large gear 218, so that the slide groove on the large gear 218 drives the four push blocks 219 to gather inward, so that the four push blocks 219 clamp the meshing sleeve;

[0071] In order to better fix the engagement sleeve on the equipment and ensure the cutting effect, when the sliding frame 203 drives the cylindrical rod 204 to move forward, it will also drive the fixed connecting plate 206, the servo electric cylinder 207, the sliding block 208, the connecting rod I 209 and the connecting rod II 210 to move forward, and further drive the sliding block 208 to move forward through the extension of the servo electric cylinder 207, thereby pushing the connecting rod I 209 and the connecting rod II 210 to swing, and then the connecting rod I 209 and the connecting rod II 210 rotate the connection to contact and squeeze the inner wall of the engagement sleeve, so that the engagement sleeve is better squeezed and fixed on the equipment;

[0072] The cylindrical gear V310 is driven to rotate by the small motor 309, and then the cylindrical gear VI311 is driven to rotate. Due to the ratchet inside the cylindrical gear VIII313, the cylindrical gear VIII313 cannot be driven at this moment; the cylindrical gear VI311 drives the cylindrical gear VII312 to rotate, thereby driving the rotating circular support plate 315 to rotate, and further driving the multiple conversion tool head structures to rotate, when the required tool head rotates to the position facing the mechanical clamp 305;

[0073] The small motor 309 rotates in the opposite direction to drive the cylindrical gear VIII 313 to rotate, and then drives the cylindrical gear IX 314 to rotate. Due to the ratchet inside the cylindrical gear VI 311, the cylindrical gear VI 311 cannot be driven at this moment; the cylindrical gear VIII 313 drives the cylindrical gear IX 314 to rotate, thereby driving the sliding pulley 307 and the rotating circular plate 302 to rotate, and further drives the third screw moving mechanism 303, the hand wheel 304 and the mechanical clamp 305 to rotate, so that the mechanical clamp 305 is directed toward one of the conversion tool head structures;

[0074] The motor of the mechanical clamp 305 drives the lead screw E of the mechanical clamp 305 to rotate, thereby driving the clamp E of the mechanical clamp 305 to clamp the cutter head, and then the motor connected to the support frame 316 drives the cam II 317 to rotate, so that the cam II 317 pushes the sliding support plate 321, so that the rod of the sliding support plate 321 pushes the clamping rod I 319 and the clamping rod II 320 to rotate about the middle axis, so that the clamping rod I 319 and the clamping rod II 320 release the cutter head;

[0075] By manually rotating the hand wheel 304, the mechanical clamp 305 is driven to rotate, and the tilt angle of the mechanical clamp 305 and the cutter head is further adjusted;

[0076] The small motor 309 rotates to drive the cylindrical gear VIII 313 to rotate, and then drives the cylindrical gear IX 314 to rotate; thereby driving the sliding pulley 307 and the rotating circular plate 302 to rotate, and further driving the third screw moving mechanism 303, the hand wheel 304 and the mechanical clamp 305 to rotate, so that the mechanical clamp 305 drives the cutter head to rotate toward the direction of the rotating cylindrical barrel 213;

[0077] Since the sliding pulley 307 is slidably mounted in the slide groove of the square frame 306, and the rear end of the sliding pulley 307 is fixedly connected to the spring, the belt wrapped around the outer side of the rotating circular plate 302, the sliding pulley 307 and the cylindrical gear IX 314 can be kept in a tensioned state;

[0078] The motor B of the second screw moving mechanism 301 drives the screw B of the second screw moving mechanism 301 to rotate, thereby driving the slider B of the second screw moving mechanism 301 to move, thereby driving the rotating circular plate 302 to move forward and backward, thereby driving the third screw moving mechanism 303, the hand wheel 304, the mechanical clamp 305 and the cutter head to move forward and backward, thereby adjusting the front and rear position of the cutter head according to different meshing sleeves;

[0079] The motor C of the third screw moving mechanism 303 drives the screw of the third screw moving mechanism 303 to rotate, thereby driving the slider C of the third screw moving mechanism 303 to move, thereby driving the hand wheel 304, the mechanical clamp 305 and the cutter head to move left and right, so as to adjust the position of the cutter head according to the cutting requirements;

[0080] During the cutting process, the position of the cutter head is adjusted so that the cutter head is close to the meshing sleeve, and the motor inside the supporting circular frame 211 drives the cylindrical gear II 212 to rotate, thereby driving the rotating cylindrical barrel 213 to rotate, thereby driving the meshing sleeve to rotate, so as to cut the meshing sleeve;

[0081] In order to automatically cut the two ends of the meshing sleeve, the motor A of the first screw moving mechanism 101 drives the screw A of the first screw moving mechanism 101 to rotate, thereby driving the slider A of the first screw moving mechanism 101 to move, thereby driving the connecting frame 102 to move, further driving the clamping mechanism 103 and the cylindrical gear I 104 to move, so that the clamping mechanism 103 is close to the meshing sleeve, and then the motor D of the clamping mechanism 103 drives the screw D of the clamping mechanism 103 to rotate, thereby driving the slider D of the clamping mechanism 103 to clamp the meshing sleeve;

[0082] The servo electric cylinder 207 is extended and retracted to drive the sliding block 208 to move, thereby driving the connecting rod I 209 and the connecting rod II 210 to swing, so that the rotating connection between the connecting rod I 209 and the connecting rod II 210 and the inner side of the engagement sleeve are no longer in contact;

[0083] Then, the motor on the fixed frame 201 drives the cam I 202 to rotate, so that the cam I 202 no longer pushes the sliding frame 203, and the cylindrical rod 204 and the sliding frame 203 are driven to move backward through the telescopic spring I 205, thereby driving the spur rack II 214 to move, thereby driving the cylindrical gear III 215 to rotate, further driving the bevel gear 216 to rotate, thereby driving the bevel gear on the shaft of the cylindrical gear IV 217 to rotate, and then driving the cylindrical gear IV 217 to rotate, thereby driving the large gear 218 to rotate, further causing the slide groove on the large gear 218 to move, so that the slide groove on the large gear 218 drives the four push blocks 219 to move outward, so that the four push blocks 219 release the meshing sleeves;

[0084] The motor A of the first screw moving mechanism 101 drives the screw A of the first screw moving mechanism 101 to rotate, thereby driving the slider A of the first screw moving mechanism 101 to move, thereby driving the connecting frame 102 to move, further driving the clamping mechanism 103 and the cylindrical gear I104 to move, and then driving the clamping mechanism 103, the cylindrical gear I104 and the meshing sleeve to move backward. Due to the ratchet inside the cylindrical gear I104, when the clamping mechanism 103 moves backward, the cylindrical gear I104 and the spur rack I105 are meshed, and the cylindrical gear I104 rotates, thereby driving the clamping mechanism 103 to rotate, thereby driving the meshing sleeve to flip;

[0085] The motor A of the first screw moving mechanism 101 drives the screw A of the first screw moving mechanism 101 to rotate, thereby driving the slider A of the first screw moving mechanism 101 to move, thereby driving the connecting frame 102 to move, and further driving the clamping mechanism 103 and the cylindrical gear I 104 to move; thereby driving the meshing sleeve to be inserted into the middle position of the four pushing blocks 219;

[0086] After the meshing sleeve is processed, the motor on the fixed frame 201 drives the cam I 202 to rotate, so that the cam I 202 no longer pushes the sliding frame 203, and the cylindrical rod 204 and the sliding frame 203 are driven to move backward through the telescopic spring I 205, thereby driving the spur rack II 214 to move, thereby driving the cylindrical gear III 215 to rotate, further driving the bevel gear 216 to rotate, thereby driving the bevel gear on the shaft of the cylindrical gear IV 217 to rotate, and then driving the cylindrical gear IV 217 to rotate, thereby driving the large gear 218 to rotate, further causing the slide groove on the large gear 218 to move, so that the slide groove on the large gear 218 drives the four push blocks 219 to move outward, so that the four push blocks 219 release the meshing sleeve, and the meshing sleeve is taken away by a person.
