[0057] Before processing, the gear is first stored between the fixed clamp 4021 and the movable clamp 4022, and then the electric push rod 4023 is started to tighten the movable clamp 4022, so that the distance between the movable clamp 4022 and the fixed clamp 4021 is reduced, and the current internal gear is clamped and fixed. After the processing is completed, the gear is moved to the expansion table 3 through the second electric slide rail 401, and then the electric push rod 4023 is started again to open the movable clamp 4022, so that the gear will fall to the push plate 8 for subsequent automatic discharge. The above structure can enable the present application to realize automatic discharge and fast loading operations, so that the processing efficiency is improved.

[0058] In the specific configuration, an extension frame 403 is fixedly installed on one side of the fixed clamping plate 4021, a rotation groove 4031 is opened inside the extension frame 403, a rotation sleeve 4032 is rotatably installed inside the rotation groove 4031, and a cleaning brush 4033 for assisting cleaning of the tooth-pulling rod 9 is installed on the inner wall of the rotation sleeve 4032;

[0059] A groove 4034 is provided at the bottom of the rotating sleeve 4032, and a limit movable ring 4036 is movably installed inside the groove 4034 through a supporting spring 4035.

[0060] When the gear is discharged, the extension frame 403 will be located at the discharge port 404. Due to the hollowness below, the support spring 4035 can push the limiting movable ring 4036 downward, so that the bottom of the limiting movable ring 4036 extends out, so that a number of matching tooth grooves 4037 are inserted into the matching teeth 4052, and the limiting movable ring 4036 is limited up and down by the limiting column 4038, so that the guide sleeve 405 will drive the rotating sleeve 4032 to rotate when it rotates, wherein the current tooth pulling rod 9 is reset upward, and the cleaning brush 4033 provided on the inner wall of the rotating sleeve 4032 can be used to automatically clean the tooth pulling rod 9 with the lubricating fluid, so that the tooth pulling rod 9 is cleaned while it is reset. Compared with the existing tooth pulling device, the present application does not require manual cleaning by personnel, and the cleaning and resetting links are combined together to greatly reduce the cleaning time and ensure the cleaning effect.

[0061] It should be noted that a drain port 404 is provided on the outer side of the through hole 11, a guide sleeve 405 is rotatably mounted on the inner wall of the drain port 404 through a rotating sleeve 4053, a matching tooth 4052 for matching with a plurality of matching tooth grooves 4037 is provided on the upper side of the inner wall of the guide sleeve 405, and a guide vane 4051 is fixedly mounted on the lower side of the inner wall of the guide sleeve 405;

[0062] The rotating sleeve 4053 is fixedly installed on the outside of the guide sleeve 405 . A driven gear ring 4054 is provided on the outer surface of the rotating sleeve 4053 . The transmission gear 14 is meshed with the driven gear ring 4054 .

[0063] During the processing, the lubricating liquid will continue to spray downward. In order to avoid overflow caused by excessive lubricating liquid, the second belt shaft 13 can be driven to rotate through the transmission belt 2042, so that the transmission gear 14 at the upper end of the second belt shaft 13 engages with the driven gear ring 4054, and then the driven gear ring 4054 rotates. The rotation of the driven gear ring 4054 will make the guide sleeve 405 cooperate with the guide blade 4051, which can guide the excess lubricating liquid to be discharged downward, avoiding the leakage of excessive lubricating liquid.

[0064] The working principle of this inner ring gear processing and pulling gear device:

[0065] When in use, the gear is first stored between the fixed clamping plate 4021 and the movable clamping plate 4022, and then the movable clamping plate 4022 is tightened by starting the electric push rod 4023, so that the distance between the movable clamping plate 4022 and the fixed clamping plate 4021 is reduced, and the gear currently inside is clamped and fixed;

[0066] After the fixation is completed, the inner ring of the gear is aligned with the through hole 11 through the second electric slide rail 401, and then the driving motor 2043 is started to rotate the positive and negative screw rods 204. The position of the slide seats 203 on the upper and lower sides is adjusted by the limited cooperation between the guide rail 202 and the slide seat 203, so that the clamping sleeve 2033 drives the tooth-pulling rod 9 to move downward, and the tooth-pulling operation is realized;

[0067] During the tooth pulling process, the lubricating liquid in the water tank 501 is introduced from the delivery pipe 507 into the annular channel 504 by starting the delivery pump 506, and then the lubricating liquid is sprayed to the current tooth pulling position of the gear by using a plurality of spray heads 505, and the annular frame 503 is arranged above the gear, so as to achieve comprehensive lubrication of the gear and the tooth pulling rod 9;

[0068] When the teeth are pulled halfway, the bottom of the tooth pulling rod 9 will contact the clamping sleeve 2033 at the lower end. After the contact, the hydraulic fluid inside the connecting pipe 206 can be controlled by using the control pump 207, so that the hydraulic fluid moves to the hydraulic groove 2051 of the required side. The hydraulic groove 2051 receives a large amount of hydraulic fluid, so that the contraction pressure rod 2052 moves toward the movable groove 2031, thereby pressing the movable plate 2032, so that the extension sleeve 205 fixes the current docking shaft 10. At the same time, the other end releases the pressure on the movable plate 2032 due to the decline of the hydraulic fluid, realizing the up and down switching of the tooth pulling rod 9, so that the tooth pulling rod 9 is fixed on the clamping sleeve 2033 at the lower end, and then the drive motor 2043 is started in reverse to perform the other half of the tooth pulling operation.

[0069] After the tooth pulling is completed, the tooth pulling rod 9 enters the through hole 11, and then the second electric slide rail 401 is used to move the gear to the expansion table 3, and then the electric push rod 4023 is started again to open the movable clamping plate 4022, so that the gear will fall to the push plate 8 for subsequent automatic discharge;

[0070] During the discharge process, when the extension frame 403 is located at the discharge port 404, the support spring 4035 can push the limiting movable ring 4036 downward due to the hollowness below, so that the bottom of the limiting movable ring 4036 extends out, so that a number of matching tooth grooves 4037 are inserted into the matching teeth 4052, and the limiting movable ring 4036 is limited up and down by the limiting column 4038, so that the guide sleeve 405 will drive the rotating sleeve 4032 to rotate when it rotates, wherein the current pulling tooth rod 9 is reset upward, and the cleaning brush 4033 provided on the inner wall of the rotating sleeve 4032 can be used to automatically clean the pulling tooth rod 9 with the lubricating fluid, so that the pulling tooth rod 9 is cleaned while it is reset, and then the next round of processing is carried out.

[0071] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
