Description

Technical Field

[0001] The present invention belongs to the technical field of planet carrier processing, and particularly relates to a planet carrier processing device and a using method thereof. Background Art

[0002] The planet carrier is one of the main components of the planetary gear transmission device, and the planet wheel shaft or bearing is installed on the planet carrier; the planet carrier is one of the main components of the planetary gear transmission and is a complex-structured part. The reasonable structure of the planet carrier should be light in weight, good in rigidity, and convenient for processing and assembly. Its common structural forms are three types: double-side plate integral type, double-side plate separated type, and single-side plate type.

[0003] In order to improve the accuracy and rapidity of the installation of multiple planet wheels and planet wheel shafts on the planet carrier, during the processing of the planet carrier, it is necessary to polish the multiple gear mounting through holes and the bosses inside the through holes on the planet carrier to facilitate the stable and accurate installation of the planet wheel shafts;

[0004] However, for the existing equipment for polishing the through holes where the planet wheels on the planet carrier are installed, most of them directly clamp the planet carrier to be polished on the workbench, and then the operator holds a grinding machine and inserts the grinding head into the through hole for grinding. Obviously, this method not only requires the operator to frequently adjust the position of the planet carrier to polish multiple mounting through holes, but also it is difficult to polish the bosses inside the mounting through holes, which will affect the accuracy and installation precision of the installation of the planet wheels and planet wheel shafts on the planet carrier. Summary of the Invention

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0014] Further, the grinding disc docking mechanism includes a pushing plate. A square guide groove is formed downward at the center of the upper arc surface of the lifting seat. The pushing plate is connected with the piston rod of the hydraulic cylinder fixed at the bottom of the square guide groove;

[0015] An installation disc is fixed on the top of the pushing plate through a support block, and hidden cavities are formed inside both ends of the installation disc;

[0016] Pad discs are slidably arranged in the symmetric hidden cavities. A grinding disc is installed on the outer side surface of the pad disc. The pad disc and the grinding disc are both connected through a connecting rod, and the outer end of the connecting rod is detachably connected with the grinding roller.

[0017] Further, the grinding disc docking mechanism further includes a first bevel plug and a second bevel plug. A counterbore is formed inside the grinding roller, so that the grinding roller is connected with the shaft rod through a countersunk screw. A plurality of first bevel sockets with a "right triangle" cross-section are circumferentially arranged on the hole wall of the counterbore;

[0018] The connecting rod is slidably inserted into the counterbore. A plurality of concave grooves are circumferentially arranged on the outer circumferential surface of the connecting rod. A first bevel plug with a "trapezoid" cross-section is slidably connected in each concave groove through a spring member, and the bevel end of the first bevel plug is slidably inserted into the first bevel socket;

[0019] A plurality of concave grooves are also circumferentially arranged on the outer circumferential surface of the pad disc. A second bevel plug with a "trapezoid" cross-section is slidably connected in each concave groove through a spring member. A plurality of second bevel sockets identical to the first bevel sockets are correspondingly formed on the cavity wall of the hidden cavity, and the second bevel plug is slidably inserted into the second bevel socket;

[0020] A positioning support block is fixed on the bottom of the hidden cavity along the depth direction thereof, and the positioning support block contacts with the pad disc hidden in the hidden cavity.

[0021] Further, the four side walls of the pushing plate are in fitting contact with the four groove walls of the square guide groove, and a collection cavity is formed inside the pushing plate. The upper cavity wall of the collection cavity is in a mesh shape. A dust suction pipe is communicated with the collection cavity and extends out of the lifting seat.

[0022] Further, cleaning cavities are provided on the two side groove walls of the square guide groove. A plurality of scraping blades are rotatably installed at the bottom of the cleaning cavity through a shaft pipe. A docking pull rod is slidably inserted into the shaft pipe through a bearing. A docking hole is provided at the end of the docking pull rod close to the square guide groove.

The outer end of the docking pull rod is connected to the piston rod of the fixed hydraulic cylinder through a connecting strip.

[0023] Further, a dust suction pipe is also correspondingly communicated with the bottom of the cleaning cavity for collecting and discharging the metal chips scraped in the cleaning cavity.

[0024] The present invention provides a use method of a planet carrier processing device, which is applicable to the above-mentioned planet carrier processing device. The method includes the following steps:

[0025] S1: Hoist the planet carrier body to be polished above the lifting seat. The lifting rollers support the planet carrier body. Driven by the driving unit on the base body, the symmetrical vertical brackets make the symmetrical clamping disks clamp the lifted planet carrier body.

[0026] S2: Control the grinding disk docking mechanism to rise in the lifting seat, so that the grinding disks are correspondingly inserted into the cavity formed between the two webs and the planet holes to be polished, and the left and right grinding disks will correspond to the convex platforms on the inner side of the planet holes.

[0027] S3: The grinding rollers on the grinding mechanism will be inserted into the planet holes of the planet carrier body, and the grinding rollers will be connected to the grinding disks. Then, the grinding rollers rotate in the planet holes to polish the hole walls, and the rotation of the grinding disks can polish the convex surfaces on the inner side of the planet holes.

[0028] S4: After the corresponding planet holes are polished, the grinding rollers and the grinding disks are disconnected. The grinding rollers are disengaged from the planet holes. The grinding disks are retracted into the lifting seat driven by the grinding disk docking mechanism. At this time, through the cooperation of the back shaft and the servo motor, the clamping disks can drive the clamped planet carrier body to rotate, so that another group of planet holes on the planet carrier body correspond to the grinding mechanism, and then repeat the above steps to facilitate the rapid polishing of the other groups of planet holes and the inner convex platforms on the planet carrier body.

[0029] The present invention has the following beneficial effects:

[0030] 1. Through the cooperation of the symmetrical grinding mechanism and the grinding disc docking mechanism that can be lifted inside the lifting seat in the present invention, the symmetrical grinding rollers can be inserted into the segmented and aligned planetary holes, and the symmetrical grinding discs are inserted between two segmented planetary holes and connected to the grinding rollers. Thus, when the grinding rollers grind the inner wall of the planetary holes, the grinding discs will simultaneously grind the bosses on the inner side, thereby improving the efficiency and precision of grinding and polishing multiple planetary holes on the planetary carrier.

[0031] 2. In the present invention, since the grinding rollers and the grinding discs are connected and disassembled by means of internal buckling, therefore, it will not interfere with the rapid and accurate grinding and polishing of the inner hole wall of the planetary holes by the grinding rollers and the end faces of the bosses by the grinding discs. The design of the positioning support blocks can position and support the cushion discs that slide back into the hidden cavity, preventing the grinding discs from excessively sliding during the retraction into the hidden cavity, resulting in misalignment between the multiple second inclined surface inserts and the multiple second inclined surface jacks. This will not only affect the stable storage of the grinding discs in the hidden cavity but also affect the accurate disconnection between the grinding discs and the grinding rollers.

[0032] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0051] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0052] Please refer to Figures 1-8As shown in the figure, the present invention is a planet carrier processing device, including a base body 1. Vertically arranged brackets 2 are symmetrically disposed on the upper surface of the base body 1, and clamping discs 21 are rotatably installed on the corresponding sides of the vertically arranged brackets 2 respectively; a lifting seat 3 is fixedly provided on the upper surface of the base body 1, and the upper surface of the lifting seat 3 is in the shape of an arc-shaped groove, and lifting rollers 31 are symmetrically rotatably installed on the upper surface thereof. The symmetrically arranged lifting rollers 31 are used for lifting and supporting the planet carrier body 8 to be polished; grinding mechanisms 4 are arranged on both of the symmetrically arranged vertically arranged brackets 2, and the grinding rollers 41 of the grinding mechanisms 4 correspond to the planet holes 81 of the lifted planet carrier body 8; a liftable grinding disc docking mechanism 5 is installed on the lifting seat 3, and the grinding disc docking mechanism 5 slides and inserts into the planet carrier body 8, so that the grinding disc 51 of the grinding disc docking mechanism 5 is docked with the grinding roller 41;

[0053] Specifically, in the present invention, two vertical brackets 2 that can slide symmetrically are provided on the base body 1. The lifting seat 3 can lift and support the planetary gear to be polished, so that the two orifices of the mounting through-hole on the planetary gear are respectively aligned with the polishing mechanisms 4 mounted on the two vertical brackets 2. When the two vertical brackets 2 move towards the two side surfaces of the planet carrier 8, the clamping disc 21 will clamp the planet carrier 8. Then, the grinding disc docking mechanism 5 is controlled to rise in the lifting seat 3, so that the grinding disc 51 is correspondingly inserted into the cavity formed between the two webs and the planetary hole 81 to be polished. Moreover, the left and right grinding discs 51 will correspond to the bosses 82 on the inner side surface of the planetary hole 81. At this time, the grinding roller 41 on the polishing mechanism 4 will be inserted into the planetary hole 81 of the planet carrier 8, and the grinding roller 41 will be connected to the grinding disc 51. Furthermore, the grinding roller 41 rotates in the planetary hole 81 to polish its hole wall, and the rotation of the grinding disc 51 can polish the surface of the boss 82 on the inner side of the planetary hole 81. After the corresponding planetary hole 81 is polished, the corresponding side boss 82 will also be polished synchronously. Then, the grinding roller 41 and the grinding disc 51 are disengaged, the grinding roller 41 is disengaged from the planetary hole 81, and the grinding disc 51 is retracted into the lifting seat 3 under the drive of the grinding disc docking mechanism 5. At this time, the clamping disc 21 can drive the clamped planet carrier 8 to rotate through the cooperation of the back shaft and the servo motor, so that another set of planetary holes 81 on the planet carrier 8 is aligned with the polishing mechanism 4. Then, the above steps are repeated to connect the grinding roller 41 and the grinding disc 51, which is convenient for quickly polishing the other sets of planetary holes 81 and the inner bosses 82 on the planet carrier 8. Therefore, through the cooperation of the symmetric polishing mechanisms 4 and the grinding disc docking mechanism 5 that can be lifted and lowered in the lifting seat 3, the symmetric grinding rollers 41 can be inserted into the segmented and aligned planetary holes 81, and the symmetric grinding discs 51 are inserted between the two segmented planetary holes 81 and connected to the grinding rollers 41. Furthermore, when the grinding rollers 41 polish the hole walls of the planetary holes 81, the grinding discs 51 will synchronously polish the bosses 82 on the inner side surfaces, which can improve the efficiency and accuracy of polishing multiple planetary holes 81 on the planet carrier 8. The lifting rollers 31 on the lifting seat 3 can rotate and lift the planet carrier 8 being normally polished, preventing the planet carrier 8 from being too heavy and affecting the stable driving rotation of the clamped planet carrier 8 by the clamping disc 21.

[0054] In this embodiment, the grinding mechanism 4 includes a synchronous belt assembly 42. The synchronous belt assembly 42 is installed on the back surface of the vertical bracket 2, and the driving pulley of the synchronous belt assembly 42 is connected to a servo motor fixedly arranged on the back surface of the vertical bracket 2; the driven pulley of the synchronous belt assembly 42 is sleeved on the shaft rod 43, and the shaft rod 43 slidably passes through the vertical bracket 2 and is connected with a grinding roller 41; a long key groove 45 that slidably cooperates with a key block 44 on the inner circumferential surface of the driven pulley is formed on the outer circumferential surface of the shaft rod 43; the outer end of the shaft rod 43 is sleeved with a connecting disk 46 through a bearing, and the extension protrusion of the connecting disk 46 is connected to the piston rod of a hydraulic cylinder 47 fixedly arranged on the vertical bracket 2.

[0055] Specifically, when the piston rod of the hydraulic cylinder 47 extends and retracts, it will push the shaft rod 43 to slide horizontally in the left - right direction through the connecting disk 46, so as to facilitate the grinding roller 41 at the end of the shaft rod 43 to be inserted into the aligned planetary holes 81 on the lifted and clamped planetary frame 8. The servo motor fixedly arranged on the back surface of the vertical bracket 2 will drive the driven pulley to rotate through the synchronous belt assembly 42, and then the shaft rod 43 that cooperates with the key block 44 and the long key groove 45 will rotate synchronously, so as to facilitate the grinding roller 41 to rotate in the planetary holes 81 to polish the hole walls.

[0056] In this embodiment, the grinding disk docking mechanism 5 includes a pushing plate 52. A square guide groove 32 is opened downward at the center of the upper arc surface of the lifting seat 3. The pushing plate 52 is connected to the piston rod of a hydraulic cylinder 47 fixedly arranged at the bottom of the square guide groove 32; an installation disk 54 is fixedly arranged at the top of the pushing plate 52 through a support block 53, and hidden cavities 541 are formed inside both ends of the installation disk 54; cushion disks 55 are slidably arranged in the symmetric hidden cavities 541, grinding disks 51 are installed on the outer side surfaces of the cushion disks 55, and both the cushion disks 55 and the grinding disks 51 are connected through connecting rods 56. The outer ends of the connecting rods 56 are detachably connected to the grinding rollers 41.

[0057] Specifically, when the planet carrier 8 is placed on the lifting seat 3, the symmetric lifting rollers 31 will lift and support the planet carrier 8 at this time, and align the planet hole 81 to be polished with the polishing roller 41. At this time, the piston rod of the hydraulic cylinder 47 in the square guide groove 32 is extended, so that it pushes the disc-shaped mounting plate 54 to rise through the pushing plate 52 and the support block 53 and inserts it into the cavity formed between the two webs and the planet hole 81 to be polished. And the polishing disc 51 in the hidden cavity 541 corresponds to the boss 82 inside the planet hole 81. When the polishing roller 41 is continuously inserted into the planet hole 81, the end of the polishing roller 41 will be synchronously inserted into the hidden cavity 541 and connected to the polishing disc 51 correspondingly. Then, the backward push of the polishing roller 41 will drive the polishing disc 51 to slide out of the hidden cavity 541 and fit onto the end face of the boss 82. Furthermore, when the polishing roller 41 rotates in the planet hole 81 to align with the inner hole wall for polishing, the sliding-out polishing disc 51 will synchronously polish the end face of the boss 82, so that the planet hole 81 and the end face of the inner boss 82 can be automatically polished synchronously. And the polishing roller 41 can rotate and polish in the planet hole 81 and also slide and polish, thereby improving the polishing accuracy of the planet hole 81. When the polishing roller 41 slides and polishes, at this time, the polishing disc 51 will perform intermittent polishing on the end face of the boss 82 to prevent the polishing disc 51 from continuously contacting the end face of the boss 82, resulting in unnecessary damage due to over-polishing. When the planet hole 81 and the end face of the inner boss 82 are polished, at this time, the polishing roller 41 will push the polishing disc 51 to slide back into the hidden cavity 541. At this time, the polishing roller 41 will be separated from the polishing disc 51 synchronously. Then, the polishing roller 41 will disengage from the planet hole 81. And the piston rod of the hydraulic cylinder 47 is retracted, which will drive the mounting plate 54 to slide downward from the cavity and be retracted into the square guide groove 32 through the pushing plate 52. Furthermore, neither the polishing roller 41 nor the polishing disc 51 will interfere with the normal rotation of the clamped planet carrier 8 on the lifting seat 3. Furthermore, it will not interfere with the alignment of other planet holes 81 on the rotated planet carrier 8 with the polishing roller 41 for polishing.

[0058] In this embodiment, the grinding disc docking mechanism 5 also includes a first bevel plug block 57 and a second bevel plug block 58. A countersunk hole 411 is provided inside the grinding roller 41, so that the grinding roller 41 is connected to the shaft 43 through a countersunk screw, and a plurality of first bevel plug holes 412 with a "right triangle" cross section are provided in a circumferential array on the hole wall of the countersunk hole 411; the connecting rod 56 is slidably inserted into the countersunk hole 411, and a plurality of recessed grooves 561 are provided in a circumferential array on the outer ring surface of the connecting rod 56, and each recessed groove 561 is slidably connected to a first bevel plug block 57 with a "trapezoidal" cross section through a spring member, and the first bevel plug The inclined surface end of the block 57 is slidably inserted into the first inclined surface insertion hole 412; the outer ring surface of the pad 55 is also circumferentially arrayed with recessed grooves 561, and each recessed groove 561 is slidably connected to a second inclined surface insertion block 58 with a "trapezoidal" cross-section via a spring member. The cavity wall of the hidden cavity 541 is correspondingly provided with a plurality of second inclined surface insertion holes 542 that are identical to the first inclined surface insertion holes 412, and the second inclined surface insertion blocks 58 are slidably inserted into the second inclined surface insertion holes 542; a positioning support block 59 is fixedly provided at the bottom of the hidden cavity 541 along its depth direction, and the positioning support block 59 contacts the pad 55 hidden in the hidden cavity 541;

[0059] Specifically, the grinding roller 41 is connected to the shaft 43 by a countersunk screw, so that it is easy to replace the grinding roller 41 that has been used for a long time; when the grinding roller 41 is continuously inserted into the planetary hole 81, so that the countersunk hole 411 at its end is sleeved on the connecting rod 56, the multiple first bevel plug blocks 57 installed in a circumferential array on the connecting rod 56 will be compressed into the multiple recessed grooves 561, and when the multiple first bevel plug blocks 57 are aligned with the multiple first bevel plug holes 412 opened in a circumferential array on the inner hole wall of the countersunk hole 411, the spring member in the recessed groove 561 will push the right-angled triangle part of the first bevel plug block 57 to be inserted into the first bevel plug hole 412 accordingly, and the other parts of the first bevel plug block 57 The other part will remain in the concave groove 561, making it easier to connect the grinding disc 51 to the grinding roller 41 through the connecting rod 56. As the grinding roller 41 drives the connected grinding disc 51 to disengage from the hidden cavity 541, at this time, since the triangular bevel angle of the second bevel plug 58 and the bevel angle of the second bevel insertion hole 542 are facing the notch of the hidden cavity 541, the grinding roller 41 drives the grinding disc 51 to move, causing the second bevel plug 58 to disengage from the second bevel insertion hole 542 and compress it into the concave groove 561 provided on the pad 55, thereby facilitating the grinding disc 51 to quickly disengage from the hidden cavity 541 and contact the end face of the boss 82 to be ground for grinding and polishing.

[0060] When it is necessary to disconnect the grinding roller 41 from the grinding disc 51, since the cushion disc 55 is always located in the hidden cavity 541, the second inclined surface insert block 58 will not protrude from the recessed groove 561, and thus will not interfere with the grinding disc 51 continuing to slide back into the hidden cavity 541. At this time, the grinding roller 41 pushes the grinding disc 51 into the hidden cavity 541. At this time, multiple second inclined surface insert blocks 58 will correspond to multiple second inclined surface insertion holes 542. Then, the elastic thrust of the spring member will push the triangular block of the second inclined surface insert block 58 into the second inclined surface insertion hole 542. Since the right-angle surface of the second inclined surface insertion hole 542 is parallel to the radial direction of the hidden cavity 541, the inserted second inclined surface insert block 58 can axially limit the sliding of the sliding grinding disc 51 through the cushion disc 55. Therefore, as the grinding roller 41 continues to slide into the hidden cavity 541, since the grinding disc 51 is in an axially limited state at this time, the connecting rod 56 will slide relative to the counterbore 411, so that multiple first inclined surface insert blocks 57 will disengage from multiple first inclined surface insertion holes 412. Then, the grinding roller 41 rotates a certain angle to disalign multiple first inclined surface insert blocks 57 from multiple first inclined surface insertion holes 412. When the grinding roller 41 slides out of the hidden cavity 541, the connecting rod 56 will disengage from the counterbore 411, which is convenient for the grinding roller 41 to quickly disconnect from the grinding disc 51 and will not interfere with the normal rotation of the planetary carrier 8. Since the grinding roller 41 and the grinding disc 51 are connected and disassembled by an internal buckling method, it will not interfere with the grinding roller 41 to quickly and accurately grind and polish the inner hole wall of the planetary hole 81 and the end face of the convex platform 82 by the grinding disc 51. The design of the positioning support block 59 can position and support the cushion disc 55 that slides back into the hidden cavity 541 to prevent the grinding disc 51 from over-sliding during the recovery into the hidden cavity 541, resulting in misalignment between multiple second inclined surface insert blocks 58 and multiple second inclined surface insertion holes 542, which will not only affect the stable installation and storage of the grinding disc 51 in the hidden cavity 541, but also affect the accurate disconnection between the grinding disc 51 and the grinding roller 41.

[0061] In this embodiment, the four side walls of the pushing plate 52 are in close contact with the four groove walls of the square guide groove 32, and a collection cavity 521 is formed inside the pushing plate 52. The upper cavity wall of the collection cavity 521 is in a mesh shape. A dust suction pipe is communicated with the collection cavity 521, and the dust suction pipe extends outside the lifting seat 3.

[0062] Specifically, when the grinding disc 51 grinds the end face of the convex platform 82, the metal powder generated by grinding will fall onto the mesh-shaped pushing plate 52 and then fall into the collection cavity 521, and is sucked and discharged through the dust suction pipe. The size of the pushing plate 52 is the same as the size of the square guide groove 32, which can prevent the powder generated by grinding from falling into the square guide groove 32, which will affect the normal sliding of the pushing plate.

[0063] In this embodiment, cleaning chambers 33 are formed on both side walls of the square guide groove 32. A plurality of scraping blades 61 are rotatably mounted at the bottom of the cleaning chamber 33 through a shaft tube 6. A docking pull rod 7 is slidably inserted into the shaft tube 6 through a bearing. A docking hole 71 is formed at the end of the docking pull rod 7 close to the square guide groove 32. A docking inclined hole 72 having the same structure as the first inclined surface jacking hole 412 is formed on the inner wall of the docking hole 71. The docking inclined hole 72 is correspondingly matched with the first inclined surface plug 57. The outer end of the docking pull rod 7 is connected to the piston rod of the fixed hydraulic cylinder 47 through a connecting strip;

[0064] Specifically, when the mounting disc 54 slides into the square guide groove 32 driven by the pushing plate 52, at this time, the grinding disc 51 will correspond to the cleaning chamber 33. When the piston rod of the hydraulic cylinder 47 fixed on the outer side surface of the lifting seat 3 retracts, it will drive the docking pull rod 7 to slide towards the hidden chamber 541 through the connecting strip, so that the docking hole 71 of the docking pull rod 7 is sleeved on the connecting rod 56. As the docking pull rod 7 is continuously sleeved, the triangular block of the first inclined surface plug 57 will be inserted into the inclined docking inclined hole 72 formed on the inner wall of the docking hole 71, so that the docking pull rod 7 and the connecting rod 56 are accurately connected. Then, the piston rod of the hydraulic cylinder 47 extends, so that the docking pull rod 7 drives the grinding disc 51 to move into the cleaning chamber 33, and the grinding surface of the grinding disc 51 is attached to the scraping blade 61. Furthermore, the shaft tube 6 will drive a plurality of scraping blades 61 to rotate through the synchronous belt assembly 42, so as to scrape and clean the residual metal powder on the surface of the grinding disc 51, prevent too much metal powder, and affect the grinding of the subsequent planetary carrier 8 by the grinding disc 51. The disconnection operation between the docking pull rod 7 and the connecting rod 56 is the same as that between the grinding roller 41 and the connecting rod 56. Therefore, it is convenient for the docking pull rod 7 to quickly disconnect from the connecting rod 56, so that the cleaned grinding disc 51 can quickly retract into the hidden chamber 541 for subsequent use. Since the docking pull rod 7 slides into the shaft tube 6, it will not interfere with the normal rotation of the shaft tube 6 to drive the scraping blade 61 to scrape and clean the grinding disc 51.

[0065] In this embodiment, a dust suction pipe is also correspondingly communicated with the bottom of the cleaning chamber 33 for collecting and discharging the metal debris scraped in the cleaning chamber 33; specifically, the metal powder scraped by the scraping blade 61 is sucked and discharged through the dust suction pipe at the bottom of the cleaning chamber 33.

[0066] A using method of a planetary carrier processing device, which is applicable to the above-mentioned planetary carrier processing device, and the method includes the following steps:

[0067] S1: Lift the planetary carrier 8 to be ground above the lifting seat 3, and the lifting roller 31 supports the planetary carrier 8. Driven by the driving unit on the base body 1, the symmetrical vertical brackets 2 clamp the lifted planetary carrier 8 with the symmetrical clamping discs 21;

[0068] S2: Control the grinding disc docking mechanism 5 to rise within the lifting seat 3, so that the grinding disc 51 is correspondingly inserted into the cavity formed between the two web plates and the planetary hole 81 to be ground, and the left and right grinding discs 51 will correspond to the bosses 82 on the inner side of the planetary hole 81;

[0069] S3: The grinding roller 41 on the grinding mechanism 4 will be inserted into the planetary hole 81 of the planetary frame 8, and the grinding roller 41 will be connected to the grinding disc 51. Then, the grinding roller 41 rotates within the planetary hole 81 to polish the hole wall, and the rotation of the grinding disc 51 can polish the surface of the boss 82 on the inner side of the planetary hole 81;

[0070] S4: After the corresponding planetary hole 81 is ground, the grinding roller 41 and the grinding disc 51 are disconnected, the grinding roller 41 is disengaged from the planetary hole 81, and the grinding disc 51 is retracted into the lifting seat 3 under the drive of the grinding disc docking mechanism 5. At this time, the clamping disc 21 can drive the clamped planetary frame 8 to rotate through the cooperation of the back shaft and the servo motor, so that another set of planetary holes 81 on the planetary frame 8 corresponds to the grinding mechanism 4, and then the above steps are repeated to facilitate the rapid grinding and polishing of the other sets of planetary holes 81 and the inner bosses 82 on the planetary frame 8.
