Description

Technical Field

[0001] The present invention relates to the technical field of gear processing, and in particular to a reducer gear processing device and process. Background Art

[0002] The reducer gear is a mechanical element used to transmit power and motion. Based on the involute tooth profile meshing transmission theory, the speed change between the input shaft and the output shaft is achieved through the meshing movement of the small sun gear and the planetary gear. When the sun gear rotates, the planetary gear rotates around itself and revolves around the sun gear at the same time, and finally transmits the power to the output shaft through the planetary frame, thereby reducing the speed and increasing the torque. The reducer ring gear is an important component of the reducer. The reducer ring gear is usually a large gear that meshes with the sun gear and the planetary gear. It plays the role of transmitting power and changing the transmission ratio in the reducer. As a key component of power transmission and speed regulation, the performance and precision of the reducer gear play a decisive role in the stable operation of many complex mechanical systems. The high-precision reducer gear has extremely small pitch deviation, extremely high tooth surface finish and precise transmission ratio stability to ensure that in the process of high-speed operation or small motion control, it can achieve error-free power transmission and precise positioning. When grinding the ring gear, a fixture is often used to clamp and fix the ring gear to ensure the grinding effect of the ring gear.

[0003] A Chinese patent document with announcement number CN106670967B discloses a fixing fixture for gear finishing, including a gear receiving platform, a stand and a pull rod, a stand is installed in the middle of the top of the central axis, and limiting slide grooves are installed on both sides of the top of the central axis, the inner cavities on both sides of the stand are provided with guide grooves, and limiting blocks are slidably installed in the inner cavities of the limiting slide grooves, and support plates are provided on both sides and the top of the limit blocks. A connecting shaft is movably installed in the inner cavities of the support plates on both sides of the limit blocks, and a clamping block is welded in the middle of the connecting shaft, and both ends of the connecting shaft are connected to the stand by a pull rod, and a connecting block is movably installed in the inner cavity of the stand, and the inner cavities at both ends of the connecting block are connected to the limit blocks by connecting rods.

[0004] When in use, the staff first places the gear to be processed on the central axis, and then presses the pressure rod by hand to move the limit block to both sides of the central axis to limit the gear. At the same time, the clamping block rotates downward under the action of the pull rod and the return spring inside the pull rod to clamp the gear.

[0005] However, the above patent document still has the following shortcomings: some waste residues will be generated during the grinding of the gear ring. When the ground gear ring is removed from the fixture, the waste residues ground from the gear ring are easy to adhere to the contact surface between the clamp and the gear ring, thereby affecting the clamping accuracy of the subsequent gear ring, and further affecting the grinding accuracy of the subsequent gear ring. Summary of the invention

[0006] The present invention provides a reducer gear processing device and process, aiming to solve the problem in the related art that the waste residue ground from the gear ring is easily attached to the contact surface between the clamping part and the gear ring, affecting the clamping accuracy of the subsequent gear ring.

[0007] The reducer gear processing equipment of the present invention comprises an operating cabinet, a mobile platform, a grinding mechanism and a spraying mechanism, and also comprises a clamping mechanism, wherein the clamping mechanism comprises a rotating part, a plurality of supporting members and a plurality of clamping members, wherein the rotating part is rotatably connected to the mobile platform, the supporting member comprises a rotating shaft, a plurality of supporting members and a plurality of movable sleeves, the rotating shaft is rotatably connected to the rotating part, the plurality of movable sleeves are respectively sleeved on the plurality of supporting members, the rotating shaft can rotate so that the plurality of supporting members can be replaced and used, and the gear ring is supported, and when the supporting member is facing downward, the movable sleeve scrapes off the waste residue attached to the supporting member under the action of its own gravity, and the clamping member It includes a mounting seat, an active roller, a driven roller, a steel belt, a scraper blade 1 and a scraper blade 2. The mounting seat is limitedly slidably connected to the rotating part. The active roller and the driven roller are both rotatably connected in the mounting seat. The steel belt is transmission-connected between the active roller and the driven roller. The scraper blade 1 and the scraper blade 2 are both connected to the mounting seat. The mounting seat can be close to or away from the gear ring so that the clamping part of the steel belt contacts the gear ring. A sealed space can be formed between the mounting seat, the steel belt, the scraper blade 1 and the scraper blade 2. The steel belt, the active roller and the driven roller can be transmission-connected so that the steel belt part in the sealed space can be separated from the sealed space and moved to the clamping part.

[0008] Beneficial effect: when the gear ring is clamped and fixed, the gear ring is supported by the supporting part on the supporting part, and at the same time, multiple clamping parts are close to the gear ring at the same time, so that the clamping part of the steel belt in the clamping part clamps and fixes the gear ring, the rotating part drives the gear ring to rotate and the gear ring is rotationally ground and linearly inserted through the grinding mechanism, and the grinding fluid is sprayed on the gear ring by the spraying mechanism. After the grinding of the gear ring is completed, the mobile platform drives the gear ring to move toward the opening of the operating cabinet, and drives the four clamping parts away from the gear ring, so as to release the clamping and fixing of the gear ring. After the gear ring is removed, the steel belts, active rollers and driven rollers on the four clamping parts are driven to make the steel belt part located in the sealed space break away from the sealed space and move to the clamping part, and at the same time, the scraper pair cleans the waste residue on the steel belt, and then the rotating shaft drives the multiple supporting parts to rotate, so that the multiple supporting parts can be used interchangeably, and when the supporting part is vertically downward, the supporting part can be cleaned through the movable sleeve on its outer side to avoid affecting the clamping accuracy of the subsequent gear ring.

[0009] Preferably, the support member also includes vertical plate one, vertical plate two, a protrusion and an elastic part. Vertical plate one and vertical plate two are both connected to the rotating part. The rotating shaft is rotatably connected between vertical plate one and vertical plate two. Vertical plate two is provided with a plurality of circular holes. The protrusion is connected to the rotating shaft through the elastic part. One end of the protrusion extends out of the rotating shaft and is plugged into the circular hole.

[0010] The effect is that the plugging of the protrusion and the circular hole can increase the resistance of the rotating shaft during rotation, thereby providing a supporting force for the gear ring by the supporting part.

[0011] Preferably, one end of the protrusion extending out of the rotating shaft is in an arc shape.

[0012] The effect is that when the rotating shaft rotates, the protrusion can be separated from the circular hole and the elastic part can be compressed.

[0013] Preferably, the clamping member further comprises a tooth plate 1, a gear 1 and a one-way bearing 1, the tooth plate 1 is connected to the rotating part, the gear 1 is connected to the active roller via the one-way bearing 1, and the gear 1 is meshingly connected to the tooth plate 1.

[0014] The effect is that when the mounting seat moves in a direction away from the gear ring, it can drive gear 1 to mesh with tooth plate 1 for transmission, so that gear 1 drives the active roller to rotate under the action of one-way bearing 1, thereby driving the transmission between the active roller, the driven roller and the steel belt; when the mounting seat moves in a direction close to the gear ring, gear 1 meshes with tooth plate 1 for transmission, and at this time, gear 1 will not drive the active roller to rotate under the action of one-way bearing 1.

[0015] Preferably, the clamping member also includes a pushing portion and a second driving source, the second driving source is connected to the rotating portion, the pushing portion is connected to the output shaft of the second driving source, a plurality of pushing grooves are provided on the pushing portion, and the mounting seats on the plurality of clamping members are respectively slidably connected to the plurality of pushing grooves.

[0016] The effect is that the second driving source can drive the pushing part to rotate, so that the pushing part pushes the mounting seats on the multiple clamping members through the multiple pushing grooves to move towards or away from the gear ring at the same time.

[0017] Preferably, the diameters of the active roller and the driven roller gradually decrease from both ends toward the middle.

[0018] Preferably, the outer side of the steel belt is in an arc shape, so that the outer side of the clamping part of the steel belt can contact the outer side of the gear ring.

[0019] Preferably, it also includes a transmission part, which includes a pushing frame, a guide rail, a second tooth plate, a connecting column, a second gear and a second one-way bearing. The pushing frame is connected to the mounting seat, the guide rail is connected to the rotating part, the second gear plate is slidably connected in the guide rail, the connecting column is connected to the second gear plate and plugged into the pushing frame, and the second gear is connected to the rotating shaft through the second one-way bearing.

[0020] The effect is that when the mounting seat moves in a direction away from the gear ring, the connecting column is pulled by the push frame, so that the tooth plate 2 moves in a direction away from the gear ring under the guidance of the guide rail, and when the tooth plate 2 passes through the gear 2, it meshes with the gear 2, so that the gear 2 drives the rotating shaft to rotate under the action of the one-way bearing 2, thereby providing power for the rotation of the rotating shaft. When the tooth plate 2 moves in a direction close to the gear ring and meshes with the gear 2, the one-way bearing 2 can prevent the gear 2 from driving the rotating shaft to rotate.

[0021] Preferably, the supporting portion is T-shaped.

[0022] The present invention also provides a process for machining a reducer gear, which comprises the following steps: S1: After placing the gear ring on the support part in the multiple support members, start the multiple clamping members, approach the gear ring through the multiple clamping members, and clamp and fix the gear ring; S2: Start the mobile platform to drive the gear ring to move to the bottom of the grinding mechanism; S3: Start the rotating part to drive the gear ring to rotate, start the grinding mechanism to perform rotational grinding and linear plunge grinding on the gear ring, and start the spraying mechanism to spray grinding fluid onto the gear ring; S4: After the processing of the gear ring is completed, the rotating part and the grinding mechanism are closed, and the moving platform is started to drive the processed gear ring to move to the opening of the operating cabinet; S5: starting multiple clamping members to move in a direction away from the gear ring, releasing the clamping and fixing of the gear ring, and removing the processed gear ring; S6: activating a plurality of clamping members to cause the portion of the steel strip located in the sealed space to be separated from the sealed space and moved to the clamping position; S7: starting the rotating shaft to drive the multiple supporting parts to rotate, so as to replace the supporting part supporting the gear ring, and when the supporting part is vertically downward, the movable sleeve on the supporting part cleans the waste residue on the supporting part; S8: Repeat the operations of S1 to S7.

[0023] Beneficial effect: the gear ring is supported by the supporting parts in the multiple supporting parts, and the multiple clamping parts are started to approach the gear ring at the same time, so that the clamping part of the steel belt in the clamping part clamps and fixes the gear ring, and then the gear ring is driven to rotate by the rotating part and the gear ring is rotationally ground and linearly inserted ground by the grinding mechanism, and the grinding fluid is sprayed on the gear ring by the spraying mechanism. After the gear ring is processed, the four clamping parts are driven away from the gear ring to release the clamping fixation of the gear ring, and the gear ring is removed, and the four clamping parts are started to make the steel belt part located in the sealed space break away from the sealed space and move to the clamping part, and the scraper pair is used to clean the waste residue on the steel belt, and the rotating shaft is started to drive the multiple supporting parts to rotate, and the supporting part supporting the gear ring is replaced. When the supporting part is vertically downward, the supporting part is cleaned through the movable sleeve on its outer side to avoid affecting the clamping accuracy of the subsequent gear ring.

[0024] The beneficial effects of the present invention are: 1. By replacing the steel belt clamping part and alternating between multiple support parts, the contact surface between the clamping mechanism and the gear ring can be kept clean, so as to avoid the residual slag generated during grinding on the contact surface between the clamping mechanism and the gear ring, which may affect the clamping accuracy of the subsequent gear ring, thereby enhancing the grinding accuracy of the subsequent gear ring.

[0025] 2. When in use, the protrusion is inserted into the circular hole on the second vertical plate under the action of the elastic part, providing resistance to the rotation of the shaft, so that the support part can support the gear ring.

[0026] 3. The scraper can clean the steel belt part that enters the sealed space during the steel belt transmission, so as to clamp and fix the subsequent gear ring and enhance the grinding accuracy of the subsequent gear ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] like Figures 1 to 11 As shown, the reducer gear processing equipment of the present invention includes an operating cabinet 1, a mobile platform 2, a clamping mechanism 3, a grinding mechanism 4 and a spraying mechanism. The mobile platform 2 is installed in the operating cabinet 1, the clamping mechanism 3 is connected to the mobile platform 2, and is used to clamp and fix the gear ring to be ground to ensure the grinding accuracy of the gear ring. The grinding mechanism 4 is connected to the operating cabinet 1 and is used to grind the gear ring. The spraying mechanism is connected to the operating cabinet 1 (the spraying mechanism is an existing mechanism, not shown in the figure), and is used to spray grinding fluid on the gear ring, so as to cool the gear ring during grinding and prevent the waste residue generated during the grinding of the gear ring from escaping into the air.

[0041] The gear ring is placed in the clamping mechanism 3, which clamps and fixes the gear ring and drives it to rotate. The grinding mechanism 4 is started to perform rotational grinding and linear insertion grinding on the rotating gear ring. The mobile platform 2 drives the ground gear ring to move toward the opening position of the operating cabinet 1. Finally, the staff removes the ground gear ring from the clamping mechanism 3 and replaces it with the gear ring to be ground.

[0042] like Figure 1 , Figures 3 to 11As shown, the clamping mechanism 3 includes a rotating part 31, a driving source 32, a support member 33, a clamping member 34 and a transmission member 35. The driving source 32 is connected in the mobile platform 2, and the driving source 32 is a motor. The rotating part 31 is connected to the output shaft of the driving source 32, and the driving source 32 can drive the rotating part 31 to rotate. The supporting members 33 and the clamping members 34 are each provided with four. The four supporting members 33 and the four clamping members 34 are all connected to the top of the rotating part 31, and the four supporting members 33 and the four clamping members 34 are arranged alternately in a ring shape. The gear ring to be ground can be supported by the four supporting members 33, and the gear ring can be clamped and fixed by the four clamping members 34. When the rotating part 31 rotates, the four clamping members 34 can be driven to approach or move away from the gear ring at the same time, so as to clamp or disassemble the gear ring. The transmission member 35 is provided with four. The four transmission members 35 are respectively connected between the four clamping members 34 and the four supporting members 33, and are used to drive the supporting members 33 to operate when the clamping members 34 operate.

[0043] Continue to refer Figure 1 , Figures 3 to 11 As shown, the support member 33 includes a vertical plate 1 331, a vertical plate 2 332, a rotating shaft 334, a support portion 335, a movable sleeve 336, a protrusion 337 and an elastic portion 338. The vertical plate 1 331 and the vertical plate 2 332 are both connected to the top of the rotating portion 31. The rotating shaft 334 is rotatably connected between the vertical plate 1 331 and the vertical plate 2 332. Four support portions 335 are provided. The four support portions 335 are all connected to the outer side of the rotating shaft 334, and the angle between two adjacent support portions 335 is ninety degrees. The gear ring can be supported by the support portions 335. Four circular holes 333 are provided on the vertical plate 2 332. The angle between two adjacent circular holes 333 is ninety degrees. The rotating shaft 334 is plugged with a protrusion 337. The elastic portion 338 is a compression spring. 337 is connected to the rotating shaft 334 through the elastic part 338. The protrusion 337 extends out of one end of the rotating shaft 334 in an arc shape and is plugged into the circular hole 333 to increase the resistance of the rotating shaft 334 when it rotates, thereby providing support force for the ring gear. Four movable sleeves 336 are provided, and the four movable sleeves 336 are respectively sleeved on the four supporting parts 335. After the ring gear is ground and removed, the rotating shaft 334 is driven to rotate so that the supporting part 335 supporting the ring gear is flipped downward to a vertical state. At this time, the movable sleeve 336 on the supporting part 335 moves downward by its own gravity, thereby cleaning up the waste residue on the contact part between the supporting part 335 and the ring gear for subsequent use. The supporting part 335 is T-shaped to prevent the movable sleeve 336 from falling off the supporting part 335.

[0044] Place the gear ring between the four support members 33, and support the gear ring with the support parts 335 on the four support members 33, start the four clamping members 34 to move towards the direction close to the gear ring at the same time, so as to clamp and fix the gear ring, then start the driving source 1 32 to drive the rotating part 31 to rotate, thereby driving the gear ring to rotate, and start the grinding mechanism 4 to perform rotational grinding and linear insertion grinding on the gear ring.

[0045] After the processing of the gear ring is completed, the mobile platform 2 is started to drive the gear ring to move toward the opening of the operating cabinet 1, and then the four clamping members 34 are started to move a distance away from the gear ring, and the clamping of the gear ring is released. At this time, the transmission member 35 will not drive the support member 33 to operate, so that the support member 33 continues to support the gear ring. After the processed gear ring is removed, the four clamping members 34 are started again to move a distance away from the gear ring. At this time, the transmission member 35 drives the rotating shaft 334 on the support member 33 to rotate, so that The support portion 335 supporting the gear ring is flipped downward to a vertical state, at which time the movable sleeve 336 on the support portion 335 moves downward by its own gravity, thereby cleaning up the waste residue on the contact portion between the support portion 335 and the gear ring, and the vertically upward support portion 335 rotates to a horizontal state, waiting to support the next gear ring to be processed, and then replaces the gear ring to be processed, and finally starts the four clamping members 34 to move toward the direction close to the gear ring, and clamps and fixes the gear ring. At this time, the transmission member 35 will not drive the support member 33 to operate.

[0046] Continue to refer Figure 1 , Figures 3 to 11As shown, four slide grooves 311 are arranged on the top of the rotating part 31, and four clamping members 34 are respectively slidably connected in the four slide grooves 311, and the clamping member 34 includes a mounting seat 341, an active roller 342, a driven roller 343, a steel belt 344, a scraper 1 345, a scraper 2 346, a tooth plate 1 347, a gear 1 348, a one-way bearing 1 349, a driving source 2 3410 and a pushing part 3411, the mounting seat 341 is limitedly slidably connected in the slide groove 311, the active roller 342 is rotatably connected in the mounting seat 341, and two driven rollers 343 are provided, and the two driven rollers 343 are both rotatably connected in the mounting seat 341, and the two driven rollers 343 are vertically arranged up and down, and the diameters of the active roller 342 and the two driven rollers 343 are gradually reduced from both ends to the middle part, and the steel belt 344 is transmission-connected between the active roller 342 and the two driven rollers 343, and the steel belt 344 is transmission-connected between the active roller 342 and the two driven rollers 343. The outer side of the belt 344 is in an arc shape so that the outer side of the clamping part of the steel belt 344 can contact the outer side of the gear ring, thereby clamping and fixing the gear ring. Scraper 1 345 and scraper 2 346 are both connected to the mounting seat 341. A sealed space can be formed between scraper 1 345, scraper 2 346, the mounting seat 341 and the steel belt 344. At this time, the part of the steel belt 344 located in the sealed space can avoid the waste residue generated when the gear ring is adhered to and ground, so that the steel belt 344 part can be separated from the sealed space and the gear ring can be clamped and fixed, thereby avoiding the waste residue adhering to the contact surface between the steel belt 344 and the gear ring and affecting the subsequent grinding accuracy of the gear ring. At the same time, when the steel belt 344 is transmitted, the waste residue attached to the outer side of the steel belt 344 can be scraped off and cleaned by scraper 1 345, and the cleaned part of the steel belt 344 enters the sealed space for the next use.

[0047] Tooth plate 1 347 is connected to the top of the rotating part 31, gear 1 348 is connected to the active roller 342 through a one-way bearing 1 349, gear 1 348 is meshed with tooth plate 1 347, driving source 2 3410 is connected in the rotating part 31, driving source 2 3410 is a motor, and a pushing part 3411 is connected to the output shaft of driving source 2 3410, and four pushing grooves are arranged on the top of the pushing part 3411, and the mounting seats 341 on the four clamping members 34 are respectively slidably connected in the four pushing grooves. When driving source 2 3410 is started to drive the pushing part 3411 to rotate, the mounting seats 341 on the four clamping members 34 can be pushed by the pushing part 3411 to approach or move away from the gear ring at the same time, so that the steel belts 344 on the four clamping members 34 are close to or away from the gear ring, thereby realizing the clamping, fixing or disassembly of the gear ring. When the mounting seat 341 on the four clamping members 34 is away from the gear ring, it drives gear 1 348 to mesh with tooth plate 1 347 for transmission. At this time, under the action of one-way bearing 1 349, gear 1 348 can drive the active roller 342 to rotate, so as to drive the transmission between the active roller 342, the steel belt 344 and the two driven rollers 343, so that the steel belt 344 part located in the sealed space is separated from the sealed space and moved to the clamping position, waiting for the subsequent gear ring to be clamped and fixed, so as to avoid the grinding accuracy of the subsequent gear ring being affected by the attachment of waste slag to the contact surface between the steel belt 344 and the gear ring. When the mounting seat 341 on the four clamping members 34 is close to the gear ring, it drives gear 1 348 to mesh with tooth plate 1 347 for transmission. At this time, under the action of one-way bearing 1 349, gear 1 348 will not drive the active roller 342 to rotate.

[0048] Continue to refer Figure 1 , Figures 3 to 11 As shown, the transmission member 35 includes a push frame 351, a guide rail 352, a second tooth plate 353, a connecting column 354, a second gear 355 and a second one-way bearing 356.

When the mounting seat 341 moves in a direction away from the gear ring, the connecting column 354 is pulled by the pushing frame 351, so that the second tooth plate 353 moves in a direction away from the gear ring under the guidance of the guide rail 352, and the second tooth plate 353 meshes with the second gear 355 when passing through the second gear 355, so that the second gear 355 drives the rotating shaft 334 to rotate under the action of the second one-way bearing 356, thereby driving the four supporting parts 335 to rotate, and further providing power for the replacement support of the four supporting parts 335.

[0049] like Figure 1 and Figure 2As shown, the grinding mechanism 4 includes a guide member 41, a driving member 42, a lifting member 43 and a grinding head 44.

[0050] The present invention also provides a process for machining a reducer gear, which comprises the following steps: S1: After placing the gear ring on the support portion 335 in the plurality of support members 33, the plurality of clamping members 34 are activated, and the gear ring is approached by the plurality of clamping members 34 to clamp and fix the gear ring; Specifically, the second driving source 3410 is started to drive the pushing part 3411 to rotate, and the mounting seats 341 on the four clamping members 34 are pushed by the pushing part 3411 to approach the gear ring at the same time, so that the steel belts 344 in the four clamping members 34 are close to the gear ring, and the gear ring is clamped and fixed by the clamping parts on the steel belts 344; S2: Start the mobile platform 2 to drive the gear ring to move to the bottom of the grinding mechanism 4; S3: Start the rotating part 31 to drive the gear ring to rotate, start the grinding mechanism 4 to perform rotational grinding and linear insertion grinding on the gear ring, and start the spraying mechanism to spray grinding fluid onto the gear ring; Specifically, the driving source 1 32 is started to drive the rotating part 31 to rotate, the driving member 42 is started to drive the lifting member 43 to move up and down under the guidance of the guide member 41, so as to drive the grinding head 44 to move up and down and perform rotational grinding and linear insertion grinding on the gear ring, and the spraying mechanism is started to spray the grinding fluid on the gear ring to cool the gear ring during grinding, and at the same time prevent the waste residue generated during the grinding of the gear ring from escaping into the air; S4: After the processing of the gear ring is completed, the rotating part 31 and the grinding mechanism 4 are closed, and the moving platform 2 is started to drive the processed gear ring to move to the opening of the operating cabinet 1; S5: starting the multiple clamping members 34 to move in a direction away from the gear ring, releasing the clamping and fixing of the gear ring, and removing the processed gear ring; Specifically, the second driving source 3410 is started to drive the pushing part 3411 to rotate, and the pushing part 3411 pushes the mounting seats 341 on the four clamping members 34 away from the gear ring at the same time, so that the steel belts 344 in the four clamping members 34 are away from the gear ring, thereby releasing the clamping fixation of the gear ring; S6: activating the plurality of clamping members 34 so that the portion of the steel belt 344 located in the sealed space is separated from the sealed space and moved to the clamping position; Specifically, when the mounting seats 341 on the four clamping members 34 are away from the gear ring, the gear 1 348 is driven to mesh with the tooth plate 1 347 for transmission. At this time, under the action of the one-way bearing 1 349, the gear 1 348 can drive the active roller 342 to rotate, so as to drive the transmission between the active roller 342, the steel belt 344 and the two driven rollers 343, so that the steel belt 344 part located in the sealed space is separated from the sealed space and moved to the clamping position, waiting to be clamped and fixed to the subsequent gear ring. At the same time, when the steel belt 344 is transmitted, the scraper 1 345 can be used to scrape off and clean the waste residue attached to the outside of the steel belt 344, and the cleaned steel belt 344 part enters the sealed space to be used next time. When the mounting seats 341 on the four clamping members 34 are close to the gear ring, the gear 1 348 is driven to mesh with the tooth plate 1 347 for transmission. At this time, under the action of the one-way bearing 1 349, the gear 1 348 will not drive the active roller 342 to rotate. S7: Start the rotating shaft 334 to drive the plurality of supporting parts 335 to rotate, so as to replace the supporting part 335 supporting the gear ring, and when the supporting part 335 is vertically downward, the movable sleeve 336 on the supporting part 335 cleans the waste residue on the supporting part 335; Specifically, when the mounting seat 341 moves in the direction away from the gear ring, the connecting column 354 is pulled by the pushing frame 351, so that the gear plate 353 moves in the direction away from the gear ring under the guidance of the guide rail 352. At this time, the clamping of the clamping member 34 on the gear ring is released, and the support portion 335 keeps supporting the gear ring. After the processed gear ring is removed, the gear plate 353 continues to move in the direction away from the gear ring. When the gear plate 353 passes through the gear 355, it meshes with the gear 355, so that the gear 355 drives the rotating shaft 334 to rotate under the action of the one-way bearing 356, so that the support portion 335 supporting the gear ring is flipped downward to a vertical state. At this time, the movable sleeve 336 on the support portion 335 moves downward by its own gravity, thereby cleaning the waste residue on the contact portion between the support portion 335 and the gear ring, and the vertically upward support portion 335 rotates to a horizontal state, waiting to support the next gear ring. S8: Repeat the operations of S1 to S7.
