Description

Technical Field

[0001] The present invention belongs to the technical field of gear processing equipment, and particularly relates to a gear production and processing device. Background Art

[0002] A gear is a mechanical component mainly used for transmitting power and motion. It is a mechanical component that can transmit power and motion through the meshing of teeth, and has the functions of transmitting power, changing the direction of motion, adjusting speed, and precise transmission. It is widely used in multiple fields. However, gear processing includes steps such as material preparation, rough machining, tooth profile machining, heat treatment, finish machining, inspection, and assembly. Common methods include hobbing, shaping, milling, grinding, and broaching. The specific method is selected according to the gear type and production requirements.

[0003] When rough machining small gears, most of them are manually loaded by workers, automatically clamped by a fixture, and then the gear is machined into a tooth profile by a hob, and then the workpiece is manually removed and placed in the next finish machining area for grinding. However, the whole process not only has a full loading, but also cannot be batch processed. At the same time, the gear cannot be automatically processed in sequence each time, and manual material transfer is required, resulting in high costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a gear production and processing device.

[0005] The technical solution adopted to solve the above technical problem is: A gear production and processing device includes a bottom plate. A feeding mechanism is installed at the center of the top of the bottom plate, and a loading mechanism is installed at a position on the front side near the feeding mechanism at the top of the bottom plate; A first support frame is fixedly connected to a position on the rear side near the feeding mechanism at the top of the bottom plate. A positioning mechanism is installed on the top of the first support frame, and a second support frame is fixedly connected to the other side of the bottom plate near the first support frame; An auxiliary mechanism is installed at the front end of the top of the second support frame, a hobbing mechanism is installed at the center of the top of the second support frame, and a cooling mechanism is installed at the rear end of the top of the second support frame; A grinding mechanism is installed on the positioning mechanism and the second support frame. A receiving box is provided between the first support frame and the second support frame at the top of the bottom plate. A blanking plate is fixedly connected above the receiving box on the other side of the first support frame. There are several gear blanks on the feeding mechanism.

[0006] Further, the feeding mechanism includes a feeding frame fixedly connected to the center of the top of the bottom plate. A conveyor belt is installed on the feeding frame. A plurality of feeding grooves are formed on the conveyor belt. A laser sensor is installed on one side inside the feeding frame.

[0007] Through the above technical solution, the staff places the gear blanks in the feeding trough in sequence, and the gear blanks are automatically transported by the conveyor belt. When the laser sensor detects the position of the gear blank, the conveyor belt stops driving and transmits the information to the feeding mechanism, which automatically feeds the transported gear blank without manual feeding by the staff, with high efficiency.

[0008] Furthermore, the feeding mechanism includes a first guide rail fixedly connected to one side of the front end of the bottom plate. A machine shell is slidably connected to the first guide rail. A hydraulic cylinder is installed inside the machine shell. The top end of the piston of the hydraulic cylinder is fixedly connected to a connecting plate. Four corners of the bottom of the connecting plate are fixedly connected with limiting rods, and multiple limiting rods are all slidably connected to the machine shell. A first motor is fixedly installed on the top of the connecting plate. One end of the output shaft of the first motor is fixedly connected with a finger parallel gripper. A first cylinder is fixedly installed at the position of the top of the bottom plate close to the front end of the machine shell. One end of the piston of the first cylinder is fixedly connected to the machine shell.

[0009] Through the above technical solution, when the laser sensor detects the gear blank, at this time, the hydraulic cylinder contracts downward through the piston, driving the first motor and the finger parallel gripper to move downward. When contacting the gear blank, the finger parallel gripper operates to clamp the gear blank. The hydraulic cylinder rises, and at the same time, the first motor operates to drive the clamped gear blank to rotate 90 degrees and keep parallel to the positioning mechanism. Then start the first cylinder, and the piston pushes the machine shell, thereby pushing the clamped gear blank, so as to send the gear blank to a position close to the positioning mechanism, facilitating subsequent automatic positioning and fixing, and thus facilitating automatic processing of it.

[0010] Furthermore, the positioning mechanism includes a second guide rail fixedly connected to one side of the top of the first support frame. A fixed seat is slidably connected to the second guide rail. A rotating seat is rotatably connected inside the fixed seat. One end of the rotating seat is fixedly connected with a positioning sleeve. A plurality of movable grooves are formed on the outer wall of the positioning sleeve. A fixed frame is fixedly connected inside the positioning sleeve. A plurality of first connecting rods are rotatably connected to the outer wall of the fixed frame. The outer ends of every two first connecting rods are rotatably connected with a supporting plate. A second cylinder is fixedly installed inside the fixed frame. One end of the piston of the second cylinder is fixedly connected with a movable rod. The movable rod is slidably connected to the fixed frame. The other end of the movable rod is fixedly connected with a connecting head. A plurality of second connecting rods are rotatably connected to the outer wall of the connecting head. A plurality of second connecting rods are respectively rotatably connected to the corresponding supporting plates. The center of the top of the fixed seat is fixedly installed with a second motor. One end of the output shaft of the second motor is fixedly connected to the rotating seat. A third cylinder is fixedly installed on the other side of the top of the first support frame. One end of the piston of the third cylinder is fixedly connected to the fixed seat.

[0011] Through the above technical solution, when the gear blank is sent to the middle position between the positioning mechanism and the auxiliary mechanism, the third cylinder is started at this time. The piston is used to push the fixed seat, thereby pushing the second motor, the turntable and the positioning sleeve, so that the positioning sleeve passes through the center of the gear blank, and the gear blank contacts the outer wall arc surface of the positioning sleeve. At the same time, the second cylinder is started, and the piston is used to push the movable rod, thereby pushing the connecting head. Under the action of a plurality of second connecting rods, a plurality of support plates are pushed outwards to be attached to the inner wall of the gear blank, so as to realize tightening. At this time, the feeding mechanism quickly resets, and at the same time, it cooperates with the auxiliary mechanism to position the gear blank. When processing it, the second motor is started, and the output shaft rotates to drive the turntable to rotate, thereby driving the tightened gear blank to rotate, which is convenient for processing it. The whole process does not require manual operation and positioning by the staff, and the automatic efficiency is high. After processing the gear blank, the whole positioning mechanism resets, and the gear blank automatically falls onto the blanking plate and then into the receiving box, realizing automatic material collection, so as to meet batch processing.

[0012] Further, the auxiliary mechanism includes a fourth cylinder fixedly installed at the front end of the top of the second support frame. One end of the piston of the fourth cylinder is fixedly connected with a connecting seat, and the other end of the connecting seat is rotatably connected with a push sleeve.

[0013] Through the above technical solution, after the positioning mechanism positions the gear blank, the fourth cylinder is started. The piston is used to push the connecting seat, thereby pushing the push sleeve to make the push sleeve tightly attached to the gear blank. Since the inner wall of the gear blank contacts the outer wall arc surface of the positioning sleeve and under the action of a plurality of support plates, the gear blank is further fixed to provide stability during processing. When the gear blank rotates, since the push sleeve is rotatably connected with the connecting seat, the push sleeve rotates accordingly, which does not affect its processing.

[0014] Further, the hobbing mechanism includes an electric push rod fixedly installed at the center of the top of the second support frame. One end of the piston of the electric push rod is fixedly connected with a tool holder. A hobbing cutter is installed in the tool holder. A third motor is fixedly installed on the top of the tool holder, and the bottom end of the output shaft of the third motor is fixedly connected with the upper rotating shaft of the hobbing cutter.

[0015] Through the above technical solution, after the gear blank is fixed, the third motor is started. The output shaft rotates to drive the hobbing cutter to rotate, so that the hobbing cutter performs hobbing processing on the outer wall of the gear blank. At the same time, the electric push rod is started to drive the hobbing cutter to move, realizing hobbing processing from one end to the other end of the gear blank.

[0016] Further, the cooling mechanism includes a liquid pump fixedly installed at the rear end of the top of the second support frame. One side of the top of the fixed seat is provided with a spray head. The liquid pump and the spray head are fixedly connected by a first connecting pipe. One side of the rear end of the top of the bottom plate is fixedly installed with a storage tank, and the storage tank and the liquid pump are fixedly connected by a second connecting pipe.

[0017] Through the above technical solution, when hobbing the gear blank, start the liquid pump, extract the coolant in the storage tank through the second connecting pipe, then transport it to the nozzle through the first connecting pipe, and then spray the gear blank being processed through the nozzle, effectively reducing the temperatures of the gear blank and the hob, preventing overheating, and at the same time, the chips generated during the processing can be washed away to prevent chip accumulation from affecting the processing quality.

[0018] Further, the grinding mechanism includes two fifth cylinders fixedly installed in the fixed seat and the connecting seat. One end of the pistons of the two fifth cylinders is fixedly connected to a frame. A fifth motor is installed in each of the two frames, and one end of the output shafts of the two fifth motors is respectively fixedly connected to a first grinding disc and a second grinding disc.

[0019] Through the above technical solution, after the gear blank is hobbed and formed, it needs to be ground. Start the two fifth cylinders at the same time, and both push the connected frames through the pistons, thereby driving the first grinding disc and the second grinding disc to approach both sides of the formed gear blank. At the same time, start the two fifth motors, and both drive the first grinding disc and the second grinding disc to rotate through the output shafts, realizing the grinding of both sides of the formed gear blank. This device automatically grinds the processed gear blank, eliminating the need to replace the grinding equipment, reducing the intermediate transfer steps, and greatly reducing the processing cost.

[0020] Further, a waste water tank, a waste chip tank and a gear tank are provided in the material receiving box.

[0021] Through the above technical solution, the coolant sprayed during the processing of the gear blank drops into the waste water tank, and the chips washed by the coolant drop into the waste chip tank. Finally, the processed gear blank automatically rolls into the gear tank.

[0022] Further, a plurality of first discharge ports and a plurality of second discharge ports are provided on the blanking plate.

[0023] Through the above technical solution, the plurality of first discharge ports can discharge the coolant, and the plurality of second discharge ports can discharge the washed chips. The processed gear blank finally automatically rolls into the gear tank through the blanking plate.

[0024] The beneficial effects of the present invention are as follows: (1) By designing a feeding mechanism, a loading mechanism, a positioning mechanism and an auxiliary mechanism, the present invention automatically feeds the gear blank, automatically fixes it, and also automatically unloads it after processing. The whole process does not require manual operation by workers, greatly reducing labor costs and enabling batch processing; (2) By designing a cooling mechanism, when the gear hobbing is processed, it can not only reduce the temperatures of the gear blank and the hob, but also wash away the chips generated during the processing to prevent chip accumulation from affecting the processing quality; (3) By designing a grinding mechanism, after the gear blank is processed and formed, it can automatically grind the two sides of its outer wall without replacing the grinding equipment, reducing the intermediate transfer steps and greatly reducing the processing cost.

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] As Figures 1 - 4As shown in the figure, a gear production and processing device of this embodiment includes a bottom plate 1. At the center of the top of the bottom plate 1, a feeding mechanism 2 is installed. The feeding mechanism 2 includes a feeding frame 201 fixedly connected to the center of the top of the bottom plate 1. A conveyor belt 202 is installed on the feeding frame 201. A plurality of feeding grooves 203 are formed on the conveyor belt 202. A laser sensor 204 is installed on one side inside the feeding frame 201. The staff places the gear blanks 13 in the feeding grooves 203 in sequence, and the conveyor belt 202 automatically transports the gear blanks 13. When the laser sensor 204 detects the position of the gear blank 13, the conveyor belt 202 stops driving and transmits information to the feeding mechanism 3, and then automatically feeds the transported gear blank 13. There is no need for manual feeding by the staff, and the efficiency is high. On the top of the bottom plate 1, on one side near the rear end of the feeding mechanism 2, a first support frame 4 is fixedly connected. On the top of the bottom plate 1, on the other side near the first support frame 4, a second support frame 6 is fixedly connected. There are several gear blanks 13 on the feeding mechanism 2.

[0029] As Figures 1 - 5 shown, on the top of the bottom plate 1, on one side near the front end of the feeding mechanism 2, a feeding mechanism 3 is installed. The feeding mechanism 3 includes a first guide rail 301 fixedly connected to one side of the front end of the bottom plate 1. A machine shell 302 is slidably connected to the first guide rail 301. A hydraulic cylinder 303 is installed inside the machine shell 302. The top end of the piston of the hydraulic cylinder 303 is fixedly connected to a connecting plate 304. Four corners of the bottom of the connecting plate 304 are fixedly connected with limiting rods 305. A plurality of limiting rods 305 are all slidably connected to the machine shell 302. A first motor 306 is fixedly installed on the top of the connecting plate 304. One end of the output shaft of the first motor 306 is fixedly connected with a finger parallel gripper 307. On the top of the bottom plate 1, near the front end position of the machine shell 302, a first cylinder 308 is fixedly installed. One end of the piston of the first cylinder 308 is fixedly connected to the machine shell 302. When the laser sensor 204 detects the gear blank 13, at this time, the hydraulic cylinder 303 contracts downward through the piston, driving the first motor 306 and the finger parallel gripper 307 to move downward. When contacting the gear blank 13, the finger parallel gripper 307 operates to clamp the gear blank 13. The hydraulic cylinder 303 rises, and at the same time, the first motor 306 operates to drive the clamped gear blank 13 to rotate 90 degrees and keep parallel to the positioning mechanism 5. Then start the first cylinder 308, and through the piston, push the machine shell 302, thereby pushing the clamped gear blank 13, so as to send the gear blank 13 to a position close to the positioning mechanism 5, which is convenient for subsequent automatic positioning and fixing, and thus convenient for automatic processing of it.

[0030] As Figures 1 - 11As shown in the figure, a positioning mechanism 5 is installed on the top of the first support frame 4. The positioning mechanism 5 includes a second guide rail 501 fixedly connected to one side of the top of the first support frame 4. A fixed seat 502 is slidably connected to the second guide rail 501. A rotating seat 503 is rotatably connected inside the fixed seat 502. One end of the rotating seat 503 is fixedly connected to a positioning sleeve 504. A plurality of movable grooves 505 are formed on the outer wall of the positioning sleeve 504. A fixed frame 506 is fixedly connected inside the positioning sleeve 504. A plurality of first connecting rods 507 are rotatably connected to the outer wall of the fixed frame 506. The outer ends of every two first connecting rods 507 are rotatably connected to a support plate 508. A second cylinder 509 is fixedly installed inside the fixed frame 506. One end of the piston of the second cylinder 509 is fixedly connected to a movable rod 510. The movable rod 510 is slidably connected to the fixed frame 506. The other end of the movable rod 510 is fixedly connected to a connecting head 511. A plurality of second connecting rods 512 are rotatably connected to the outer wall of the connecting head 511. The plurality of second connecting rods 512 are respectively rotatably connected to the corresponding support plates 508. The center of the top of the fixed seat 502 is fixedly installed with a second motor 513. One end of the output shaft of the second motor 513 is fixedly connected to the rotating seat 503. On the other side of the top of the first support frame 4, a third cylinder 514 is fixedly installed. One end of the piston of the third cylinder 514 is fixedly connected to the fixed seat 502. When the gear blank 13 is sent to the middle position between the positioning mechanism 5 and the auxiliary mechanism 7, at this time, the third cylinder 514 is started, and the fixed seat 502 is pushed through the piston, so as to push the second motor 513, the rotating seat 503 and the positioning sleeve 504, so that the positioning sleeve 504 passes through the center of the gear blank 13, and the gear blank 13 contacts the arc surface of the outer wall of the positioning sleeve 504. At the same time, the second cylinder 509 is started, and the movable rod 510 is pushed through the piston, so as to push the connecting head 511. Under the action of the plurality of second connecting rods 512, the plurality of support plates 508 are pushed outwards to be attached to the inner wall of the gear blank 13, so as to realize tightening. At this time, the feeding mechanism 3 quickly resets, and at the same time, it cooperates with the auxiliary mechanism 7 to position the gear blank 13. When processing it, the second motor 513 is started, and the rotating seat 503 is rotated by the rotation of the output shaft, so as to drive the tightened gear blank 13 to rotate, so as to facilitate the processing of it. The whole process does not require manual operation and positioning by the staff, with high automation efficiency. After the gear blank 13 is processed, the whole positioning mechanism 5 resets, and the gear blank 13 automatically falls onto the blanking plate 12 and then into the material receiving box 11, realizing automatic material collection, so as to meet batch processing.

[0031] As Figures 1 - 9As shown in the figure, an auxiliary mechanism 7 is installed at the front end of the top of the second support frame 6. The auxiliary mechanism 7 includes a fourth cylinder 701 fixedly installed at the front end of the top of the second support frame 6. One end of the piston of the fourth cylinder 701 is fixedly connected to a connecting seat 702. The other end of the connecting seat 702 is rotatably connected to a pushing sleeve 703. After the positioning mechanism 5 positions the gear blank 13, the fourth cylinder 701 is started. The connecting seat 702 is pushed by the piston, thereby pushing the pushing sleeve 703 to make the pushing sleeve 703 tightly fit against the gear blank 13. Since the inner wall of the gear blank 13 is in arc contact with the outer wall of the positioning sleeve 504 and under the action of multiple support plates 508, the gear blank 13 is further fixed to provide stability during processing. When the gear blank 13 rotates, since the pushing sleeve 703 is rotatably connected to the connecting seat 702, the pushing sleeve 703 rotates accordingly, which does not affect the processing of it.

[0032] As Figures 1 - 7 shown in the figure, a hobbing mechanism 8 is installed at the center of the top of the second support frame 6. The hobbing mechanism 8 includes an electric push rod 801 fixedly installed at the center of the top of the second support frame 6. One end of the piston of the electric push rod 801 is fixedly connected to a tool holder 802. A hob 803 is installed in the tool holder 802. A third motor 804 is fixedly installed at the top of the tool holder 802. The bottom end of the output shaft of the third motor 804 is fixedly connected to the upper rotating shaft of the hob 803. After the gear blank 13 is fixed, the third motor 804 is started. The hob 803 is driven to rotate by the rotation of the output shaft, so that the hob 803 performs hobbing processing on the outer wall of the gear blank 13. At the same time, the electric push rod 801 is started to drive the hob 803 to move, realizing hobbing processing from one end to the other end of the gear blank 13.

[0033] As Figures 1 - 7 shown in the figure, a cooling mechanism 9 is installed at the rear end of the top of the second support frame 6. The cooling mechanism 9 includes a liquid pump 901 fixedly installed at the rear end of the top of the second support frame 6. A spray head 902 is installed on one side of the top of the fixed seat 502. The liquid pump 901 and the spray head 902 are fixedly connected by a first connecting pipe 903. A storage tank 904 is fixedly installed on one side of the rear end of the top of the bottom plate 1. A second connecting pipe 905 is fixedly connected between the storage tank 904 and the liquid pump 901. When hobbing the gear blank 13, the liquid pump 901 is started. The coolant in the storage tank 904 is extracted through the second connecting pipe 905 and then conveyed to the spray head 902 through the first connecting pipe 903. Then, the spray head 902 sprays the gear blank 13 being processed, effectively reducing the temperature of the gear blank 13 and the hob 803, preventing overheating. At the same time, the chips generated during the processing can be washed away to prevent chip accumulation from affecting the processing quality.

[0034] As Figures 1 - 9As shown, a grinding mechanism 10 is installed on the positioning mechanism 5 and the second support frame 6. The grinding mechanism 10 includes two fifth cylinders 1001 fixedly installed in the fixed seat 502 and the connecting seat 702. One end of the pistons of the two fifth cylinders 1001 is fixedly connected to a frame 1002. A fifth motor 1003 is installed in each of the two frames 1002. One end of the output shafts of the two fifth motors 1003 is respectively fixedly connected to a first grinding disc 1004 and a second grinding disc 1005. After the gear blank 13 is formed by hobbing, it needs to be ground. At the same time, the two fifth cylinders 1001 are started, and the frames 1002 connected thereto are pushed by the pistons, so as to drive the first grinding disc 1004 and the second grinding disc 1005 to approach both sides of the formed gear blank 13. At the same time, the two fifth motors 1003 are started, and the first grinding disc 1004 and the second grinding disc 1005 are driven to rotate through the output shafts, so as to realize grinding of both sides of the formed gear blank 13. This device automatically grinds the processed gear blank 13, without the need to replace the grinding equipment, reduces the intermediate transfer steps, and greatly reduces the processing cost.

[0035] As Figures 1 - 10 shown, a material collecting box 11 is provided at the top of the bottom plate 1 near the first support frame 4 and the second support frame 6. A waste water tank 111, a waste chip tank 112 and a gear tank 113 are opened in the material collecting box 11. The coolant sprayed during the processing of the gear blank 13 drops into the waste water tank 111, and the chips washed by the coolant drop into the waste chip tank 112. Finally, the processed gear blank 13 automatically rolls into the gear tank 113.

[0036] As Figures 1 - 10 shown, a blanking plate 12 is fixedly connected above the material collecting box 11 on the other side of the first support frame 4. A plurality of first discharge ports 121 and a plurality of second discharge ports 122 are opened on the blanking plate 12. The plurality of first discharge ports 121 can discharge the coolant, and the plurality of second discharge ports 122 can discharge the washed chips. The processed gear blank 13 finally automatically rolls into the gear tank 113 through the blanking plate 12.

[0037] The working principle of this embodiment is as follows. The staff places the gear blank 13 in the feeding groove 203 in sequence, and the gear blank 13 is automatically transported by the conveyor belt 202. When the laser sensor 204 detects the position of the gear blank 13, the conveyor belt 202 stops driving and transmits the information to the feeding mechanism 3. At this time, the hydraulic cylinder 303 contracts downward through the piston, driving the first motor 306 and the finger parallel gripper 307 to move downward. When contacting the gear blank 13, the finger parallel gripper 307 operates to clamp the gear blank 13. Then, it rises through the hydraulic cylinder 303. At the same time, the first motor 306 operates to drive the clamped gear blank 13 to rotate 90 degrees and keep parallel to the positioning sleeve 504. Then, the first cylinder 308 is started, and the piston is used to push the machine shell 302, thereby pushing the clamped gear blank 13, and the gear blank 13 is sent to the position between the positioning sleeve 504 and the pushing sleeve 703; At this time, the third cylinder 514 is started, and the piston is used to push the fixed seat 502, thereby pushing the second motor 513, the rotating seat 503 and the positioning sleeve 504, so that the positioning sleeve 504 passes through the center of the gear blank 13, and the gear blank 13 contacts the outer wall arc surface of the positioning sleeve 504. At the same time, the second cylinder 509 is started, and the piston is used to push the movable rod 510, thereby pushing the connecting head 511. Under the action of multiple second connecting rods 512, multiple support plates 508 are pushed outwards to be attached to the inner wall of the gear blank 13 to achieve tightening. At this time, the feeding mechanism 3 quickly resets. Then, the fourth cylinder 701 is started, and the piston is used to push the connecting seat 702, thereby pushing the pushing sleeve 703 to make the pushing sleeve 703 tightly attached to the gear blank 13. Since the inner wall of the gear blank 13 contacts the outer wall arc surface of the positioning sleeve 504 and under the action of multiple support plates 508, the gear blank 13 is further fixed to provide stability during processing; After the gear blank 13 is fixed, the third motor 804 is started, and the hob 803 is driven to rotate through the rotation of the output shaft, so that the hob 803 performs hobbing processing on the outer wall of the gear blank 13. At the same time, the second motor 513 is started, and the rotating seat 503 is driven to rotate through the rotation of the output shaft, thereby driving the tightened gear blank 13 to rotate. And the electric push rod 801 is started to drive the hob 803 to move, realizing hobbing processing from one end to the other end of the gear blank 13. At the same time, the liquid pump 901 is started, and the coolant in the storage tank 904 is extracted through the second connecting pipe 905 and then transported to the nozzle 902 through the first connecting pipe 903, and then the nozzle 902 sprays the coolant on the gear blank 13 being processed, effectively reducing the temperature of the gear blank 13 and the hob 803 to prevent overheating. The coolant sprayed on the gear blank 13 during processing drops into the wastewater tank 111 through multiple first discharge ports 121, and the chips generated during hobbing processing of the gear blank 13 drop into the waste chip tank 112 through multiple second discharge ports 122 under the flushing of the coolant; After the gear blank 13 is formed by hobbing, it needs to be polished. Start two fifth cylinders 1001, and both drive the connected frame 1002 through the piston, so as to drive the first grinding disc 1004 and the second grinding disc 1005 to approach both sides of the formed gear blank 13. At the same time, start two fifth motors 1003, and both drive the first grinding disc 1004 and the second grinding disc 1005 to rotate through the output shaft, so as to realize the grinding of both sides of the formed gear blank 13. After the gear blank 13 is ground, the positioning mechanism 5 and the auxiliary mechanism 7 are reset, so that the processed gear blank 13 automatically drops close to the second grinding disc 1005, and finally automatically rolls into the gear groove 113 through the blanking plate 12, realizing automatic collection, and each mechanism then processes the next gear blank 13 in turn.

[0038] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
