Description

Technical Field

[0001] This invention belongs to the technical field of bearing parts processing equipment, specifically relating to an open cutting device suitable for batch manufacturing of bearing retaining rings of multiple sizes. Background Technology

[0002] Bearing retaining rings, also known as snap rings, are key components in bearing assemblies. They are installed in grooves within the outer or inner ring of the bearing, primarily serving axial positioning and preventing loosening. During manufacturing, retaining rings are first stamped into complete circular rings in a mold. Then, an opening is cut at a specific location on their circumference to give the retaining ring elastic deformation capabilities, allowing it to smoothly engage with the bearing grooves during subsequent assembly. The processing of the retaining ring opening typically involves cutting individual retaining rings one by one using cutting equipment, resulting in low production efficiency and difficulty in meeting the demands of mass production. To improve processing efficiency, some manufacturers have experimented with stacking multiple retaining rings side-by-side to form retaining ring assemblies, then using a cutting machine to cut the assemblies as a single unit, creating openings in all the retaining rings within each assembly simultaneously.

[0003] Chinese invention patent application number CN202510356887.6 discloses a clasp processing device, comprising: a base for supporting the entire device; a turntable rotatably mounted on the base; a first grinding mechanism for grinding the end face of the clasp; a second grinding mechanism for grinding the inner wall of the clasp; a third grinding mechanism for grinding the outer wall of the clasp; and four clamping mechanisms for fixing the clasp, which are evenly arranged on the turntable. The clamping mechanism includes a processing groove on the turntable, a positioning post in the processing groove, clamping rods symmetrically arranged in the processing groove, a first driving member for driving the clamping rods to rotate, a clamping rod driving assembly for driving the clamping rods to move, a mounting plate, a slide rod on the mounting plate, a first elastic member sleeved on the slide rod, a locking block on the slide rod, a positioning post driving assembly for driving the positioning post to move up and down, and a second driving member for driving the mounting plate to move horizontally. The locking block can be precisely engaged in the opening of the clasp.

[0004] However, during cutting, axial clamping force must be applied to the circlip assembly to fix each circlip. The circlips at both ends of the circlip assembly, i.e., the first and last circlips, are prone to tilting or local deformation under clamping force because they lack adjacent circlip support on one side. After cutting, their roundness and opening size are difficult to meet precision requirements, resulting in these two circlips often being non-standard, substandard parts. Removing the first and last circlips from the cut circlip assembly can effectively ensure the product qualification rate of standard circlips. After clamping, the circlips in the circlip assembly are tightly fitted together, making it difficult for operators wearing gloves to accurately and quickly peel off the individual circlips at the beginning and end, reducing production efficiency. Operators often directly pull out multiple circlips from the beginning and end of the circlip assembly and discard them, which is not only inefficient but also wastes a lot of finished circlips, reducing the production yield. Moreover, each step of processing the circlip notch is performed individually by one worker, resulting in low output per unit time. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an opening-cutting device suitable for mass production of bearing retaining rings of various sizes. Through the coordinated operation of the housing, the ring-shifting assembly, the cutting machine assembly, and the translational track assembly, this invention can automatically and quickly remove the first and last retaining rings from the cut retaining ring assembly, effectively ensuring the product qualification rate of standard retaining ring parts and improving production efficiency. It also avoids the problems of multiple rejections and incorrect rejections in retaining ring production, ensuring that each rejection action only acts on the unqualified retaining rings at the end of the retaining ring assembly, effectively preventing qualified retaining rings from being discarded along with the unqualified ones, and significantly improving the product yield. Furthermore, it can create a tight connection between various processes, eliminating waiting time between processes and realizing quasi-continuous mass production of retaining ring opening processing, significantly improving the output per unit time.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An open-end cutting device suitable for mass production of bearing retaining rings of various sizes includes a housing. The housing includes a base plate, with a side plate fixedly connected to each of the two sides of the base plate, a rear plate fixedly connected to the rear side of the base plate, and a front plate and a baffle fixedly connected to the front side of the base plate. The front plate is located between the two baffles, and the height of the baffles is less than the height of the front plate and the side plates. The inner cavity of the housing houses a ring shifting assembly, a cutting machine assembly, and a translational track assembly. The translational track assembly includes retaining ring shifting posts, a lead screw, and a translational slide rail, all aligned along their length. One of the ring shifting assemblies is slidably connected to the translational slide rail and driven by the lead screw. One end of the lead screw is fixedly connected to the center of a rocker plate, which is rotatably connected to the outer wall of the front plate. Two retaining ring shifting posts pass through the ring shifting assembly, and a retaining ring group composed of retaining rings arranged side by side can be stably placed on the two retaining ring shifting posts. The cutting machine assembly includes a cutting machine that can move perpendicular to the length direction of the retaining ring shifting posts, and the cutting machine's blade can move directly above the retaining ring shifting posts.

[0007] Furthermore, the rear plate has a ring-retrieving hole, and a ring-retrieving box is fixedly connected to the outside of the ring-retrieving hole. The two ends of the retaining ring shifting post and the lead screw are respectively fixedly connected to the inner wall surface of the ring-retrieving box away from the rear plate and the inner wall surface of the front plate. The ring-shifting assembly includes a push ring plate, which is slidably inserted into a plate base. One side of the push ring plate has a ring-shifting groove that can accommodate one retaining ring. The ring-shifting grooves of the two ring-shifting assemblies are opposite each other. The plate base of one ring-shifting assembly is slidably connected to a translation slide rail. This plate base has a threaded hole and is connected to the lead screw for transmission. The plate base of the other ring-shifting assembly is fixedly connected to the inner wall surface of the ring-retrieving box away from the rear plate. This plate base has a through hole and is rotatably connected to the lead screw.

[0008] Furthermore, the shift ring assembly includes a rack, which is fixedly connected to the side of the push ring plate. The rack meshes with a toothed ring, which is fixedly connected to the center of the output shaft of the stepper motor. The stepper motor is fixedly connected to one end of the plate base.

[0009] Furthermore, the push ring plate has a groove in the middle, through which the retaining ring shifter passes. Sliding grooves are formed on the push ring plates on both sides of the groove. A clamping plate is fixedly connected to the plate base, and a slider is fixedly connected to the inner side of the clamping plate. The push ring plates on both sides of the groove are inserted into the gap between the plate base and the clamping plate, and the slider is slidably connected in the sliding groove. The rack is located at the opening of the gap between the plate base and a clamping plate.

[0010] Furthermore, the translational track assembly includes a clamping claw that is sleeved on and slides on the translational slide rail, and the side of the clamping claw facing away from the translational slide rail is fixedly connected to the other end of the plate base away from the stepper motor.

[0011] Furthermore, the enclosure includes a top plate, which is fixedly connected to the top of the side plates and the rear plate.

[0012] Furthermore, the cutting machine assembly includes a power cord that electrically connects the cutting machine and the power supply box, which is fixedly connected to the top surface of the top plate. One end of the cutting machine is fixedly connected to the frame, and a linear motor is fixedly connected to the bottom of the frame. The linear motor is slidably connected to a linear slide rail, and both ends of the linear slide rail are fixedly connected to the side of the translation slide rail facing away from the retaining ring column and the inner wall of the side plate, respectively.

[0013] Furthermore, the enclosure includes an observation panel, with its two ends fixedly connected to the top of the front panel and the end of the top panel away from the rear panel, respectively.

[0014] Furthermore, the front panel has an operating notch located at one end of the front panel near the observation panel.

[0015] Furthermore, the box body includes box feet, and a plurality of box feet are fixedly connected to the bottom surface of the base plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention can automatically and quickly remove the first and last clasps of the clasp group after the cutting is completed, which can effectively ensure the product qualification rate of the clasp standard parts and improve production efficiency. When processing the clasp, multiple clasps are stacked side by side to form a clasp group. The operator puts the clasp group into the clasp shifting column in the box cavity. At this time, the clasp group is located between two shifting ring components. The plate seat of the shifting ring component near the front plate has a threaded hole connected to the lead screw drive. Rotate the rocker to drive the shifting ring component to move along the translation slide rail. At this time, the clasp group is pushed towards the rear plate by the push ring plate of the shifting ring component. When it is pushed to the cutting machine, the cutting machine performs an opening cut on the entire clasp group. After the opening cut is completed, continue to rotate the rocker. The clasp group after the cut is pushed out of the ring taking hole and enters the ring taking box until the clasp group is pressed against the middle by the push ring plates of the two shifting ring components. First, start the stepper motor of one of the ring shifting components. The rack and pinion drive causes the pusher plate to move downwards until the ring shifting groove on the pusher plate coincides with the central axis of the retaining ring group. At this point, the retaining ring at the end of the retaining ring group is embedded in the ring shifting groove. Then, the stepper motor is flipped, and the pusher plate moves upwards, simultaneously pushing the end retaining ring embedded in the ring shifting groove upwards. Then, start the stepper motor of the other ring shifting component and repeat the above action. After the single retaining ring at the other end of the retaining ring group is pushed away, the operator directly takes the standard retaining ring from the open ring taking box. Finally, start the stepper motor again, and both pusher plates move downwards. The retaining ring embedded in the ring shifting groove touches the retaining ring shifting post and pops out of the ring shifting groove. The two defective retaining rings at the beginning and end of the retaining ring group finally fall into the base plate or the bottom of the ring taking box.

[0017] (2) This invention can precisely remove individual clasps at the beginning and end of the clasp assembly after cutting, avoiding the discarding of qualified clasp products and improving the production yield. Each ring-shifting assembly has a ring-shifting groove on the side of the pusher plate facing the clasp assembly. The ring-shifting groove is an arc-shaped groove whose curvature matches the outer circumferential surface of the clasp. In particular, the depth of the ring-shifting groove is strictly limited to no more than the axial thickness of a single clasp. Based on this structure, when the pusher plate moves towards the clasp shifting post under the drive of the stepper motor, gear ring, and rack until the ring-shifting groove coincides with the central axis of the clasp assembly, due to the physical constraints of geometric dimensions, only the single clasp at the very end of the clasp assembly can be embedded in the ring-shifting groove. The adjacent second clasp cannot enter the groove because it exceeds the accommodating depth of the ring-shifting groove, thus achieving forced separation of the end clasp from the remaining clasps at the physical level. This single-ring receiving structure fundamentally avoids the problems of multiple rejections and incorrect rejections caused by visual judgment errors or improper operation in traditional manual rejection methods. It ensures that each rejection action only acts on the unqualified retaining rings at the end of the retaining ring group, effectively preventing qualified retaining rings from being discarded together and significantly improving the product yield.

[0018] (3) This invention can form a tight connection between each process, eliminate the waiting time between processes, realize quasi-continuous batch production of clasp opening processing, and significantly improve the output per unit time. The plate seat of the ring shifting assembly near the back plate is fixedly connected to the inner wall surface of the ring taking box away from the back plate. The pusher plate of the fixed end ring shifting assembly plays a limiting and blocking role when the clasp group is pushed out of the ring taking hole. When the operator continues to turn the rocker, the movable end ring shifting assembly pushes the cut clasp group through the ring taking hole into the ring taking box until the clasp group is pressed against the middle by the movable end pusher plate and the fixed end pusher plate. At this time, the clasp group is automatically positioned in the ring taking box without manual adjustment. After positioning, the stepper motors of the two ring shifting assemblies start and remove the first and last unqualified clasp groups in sequence according to the preset program. The rejection process can be carried out simultaneously with the preparation of the next batch of circlips. That is, while the two circlip moving components are performing the rejection action, the operator can simultaneously place the next batch of circlips to be processed on the circlip moving column. After rejection is completed, simply turning the rocker can begin the pushing and cutting of the next batch. This structural design ensures a tight connection between the feeding, pushing, cutting, pushing, and rejection processes, eliminating waiting time between processes and achieving quasi-continuous batch production of circlip opening processing, significantly improving the output per unit time.

[0023] Example

[0024] like Figures 1 to 10As shown, an open-end cutting device suitable for mass production of bearing retainers of multiple sizes includes a housing 100. The housing 100 includes a base plate 106, with a side plate 101 fixedly connected to each of the two sides of the base plate 106. A rear plate 108 is fixedly connected to the rear side of the base plate 106, and a front plate 102 and a baffle 104 are fixedly connected to the front side of the base plate 106. The front plate 102 is located between the two baffles 104, and the height of the baffles 104 is less than the height of the front plate 102 and the side plate 101. The inner cavity of the housing 100 accommodates a moving ring assembly 200, a cutting machine assembly 300, and a translation track assembly 400. The translational track assembly 400 includes retaining ring shifting posts 401, a lead screw 403, and a translational slide rail 404, all aligned along their length. One of the shifting ring assemblies 200 is slidably connected to the translational slide rail 404 and drivenly connected to the lead screw 403. One end of the lead screw 403 is fixedly connected to the center of the rocker plate 402, which is rotatably connected to the outer wall of the front plate 102. Two retaining ring shifting posts 401 pass through the shifting ring assembly 200, and a retaining ring group 500, composed of retaining rings 501 arranged side by side, can be stably placed on the two retaining ring shifting posts 401. The cutting machine assembly 300 includes a cutting machine 301, which can move perpendicular to the length direction of the retaining ring shifting posts 401. The blade of the cutting machine 301 can move directly above the retaining ring shifting posts 401.

[0025] In this invention, when processing the retaining ring 501, multiple retaining rings 501 are first stacked side by side to form a retaining ring assembly 500. Because the height of the baffle 104 is less than that of the front plate 102 and the side plate 101, an opening is formed between the upper end of the baffle 104 and the front end of the top plate 103. The operator places the retaining ring assembly 500 into the retaining ring shifting post 401 inside the cavity of the housing 100 through this opening. The plane containing the axes of the two parallel retaining ring shifting posts 401 is parallel to the horizontal plane, so the retaining ring assembly 500 can be stably placed between the two retaining ring shifting posts 401. At this time, the retaining ring assembly 500 is located between the two shifting ring assemblies 200, close to the front plate 102. The plate base 204 of the ring shifting assembly 200 has a threaded hole that is connected to the lead screw 403 for transmission. When the rocker 402 is rotated, the ring shifting assembly 200 is moved along the translation slide rail 404. At this time, the retaining ring assembly 500 is pushed towards the rear plate 108 by the pusher plate 201 of the ring shifting assembly 200. When it is pushed to the cutting machine 301, the cutting machine 301 performs an opening cut on the entire retaining ring assembly 500. After the opening cut is completed, the rocker 402 is rotated again. The retaining ring assembly 500 after the cut is completed is pushed out of the ring taking hole 109 and enters the ring taking box 110 until the retaining ring assembly 500 is pressed against the middle by the pusher plates 201 of the two ring shifting assemblies 200. The stepper motor 208 in the ring shifting assembly 200 is connected to an external power supply and controller. First, only one stepper motor 208 of the ring shifting assembly 200 is started. The transmission of the rack 207 and gear ring 209 causes the pusher plate 201 to move downwards until the ring-shifting groove 202 on the pusher plate 201 coincides with the central axis of the retaining ring assembly 500. At this point, the retaining ring 501 at the end of the retaining ring assembly 500 is inserted into the ring-shifting groove 202. Then, this stepper motor 208 is rotated, the pusher plate 201 moves upwards, and simultaneously pushes the end retaining ring 501 inserted into the ring-shifting groove 202 upwards. Then, the stepper motor 208 of another ring-shifting assembly 200 is started, and the above actions are repeated. After the single retaining ring 501 at the other end of the retaining ring assembly 500 is removed, the operator directly removes the composite standard retaining ring 501 from the open ring-retrieving box 110. Finally, the stepper motor 208 is started again, and both push ring plates 201 move downwards. The retaining ring 501 embedded in the ring-shifting groove 202 contacts the retaining ring shifting post 401 and pops out of the ring-shifting groove 202. The two unqualified retaining rings 501 at the beginning and end of the retaining ring assembly 500 finally fall into the bottom plate 106 or the bottom of the ring-retrieving box 110. In this way, the first and last retaining rings 501 of the retaining ring assembly 500 after cutting can be removed automatically and quickly, which can effectively ensure the product qualification rate of the standard retaining ring 501 parts and improve production efficiency.

[0026] Furthermore, the rear plate 108 has a ring-retrieving hole 109, and a ring-retrieving box 110 is fixedly connected to the outside of the ring-retrieving hole 109. The two ends of the retaining ring shifting post 401 and the lead screw 403 are respectively fixedly connected to the inner wall surface of the ring-retrieving box 110 away from the rear plate 108 and the inner wall surface of the front plate 102. The ring-shifting assembly 200 includes a push ring plate 201, which is slidably inserted into the plate base 204. A ring-shifting groove 202 is provided on one side of the push ring plate 201, which can accommodate one retaining ring 501. The ring-shifting grooves 202 of the two ring-shifting assemblies 200 are opposite each other. The plate base 204 of one ring-shifting assembly 200 is slidably connected to the translation slide rail 404. This plate base 204 has a threaded hole and is connected to the lead screw 403 for transmission. Another of the ring-moving components 200 has a plate base 204 fixedly connected to the inner wall surface of the ring-taking box 110 away from the rear plate 108. This plate base 204 has a through hole and is rotatably connected to the lead screw 403.

[0027] In this invention, quasi-continuous batch production of the opening processing of the retaining ring 501 can be achieved, significantly improving the output rate per unit time. The plate base 204 of the ring shifting assembly 200 near the back plate 108 is fixedly connected to the inner wall surface of the ring taking box 110 away from the back plate 108. The pusher plate 201 of the fixed end ring shifting assembly 200 acts as a limiting and blocking function when the retaining ring group 500 is pushed out of the ring taking hole 109. When the operator continuously rotates the rocker 402, the movable end ring shifting assembly 200 pushes the cut retaining ring group 500 through the ring taking hole 109 into the ring taking box 110 until the retaining ring group 500 is pressed against the middle by the movable end pusher plate 201 and the fixed end pusher plate 201. At this time, the retaining ring group 500 is automatically positioned in the ring taking box 110 without manual adjustment. After positioning, the stepper motors 208 of the two ring shifting assemblies 200 are started, and the first and last unqualified retaining rings 501 are removed in sequence according to the preset program. The unloading process can be synchronized with the preparation of the next batch of retaining rings 500. That is, after the two ring-shifting assemblies 200 complete their rejection action, the operator needs to unload the material. This is achieved by directly reversing the rocker 402, causing the movable ring-shifting assembly 200 to move away from the ring-removing hole 109 until it resets at the front plate 102. Only when the ring-removing hole 109 is not obstructed by the movable ring-shifting assembly 200 can the retaining ring 501 be unloaded. At this point, the movable ring-shifting assembly 200 has quickly reset to the front plate, and the next batch of retaining rings 501 to be processed can be placed on the retaining ring shifting column 401 for pushing and cutting. This structural design ensures a tight connection between the loading, pushing, cutting, pushing, rejection, and unloading processes. The unloading of the previous batch and the loading of the next batch can be carried out continuously, eliminating waiting time between processes and achieving quasi-continuous batch production of the retaining ring 501 opening process, significantly improving the output per unit time.

[0028] Furthermore, the shift ring assembly 200 includes a rack 207, which is fixedly connected to the side of the push ring plate 201. The rack 207 meshes with a toothed ring 209, which is fixedly connected to the center of the output shaft of the stepper motor 208. The stepper motor 208 is fixedly connected to one end of the plate base 204.

[0029] In this invention, by meshing the rack 207 with the toothed ring 209, firstly, the rise and fall of the push ring plate 201 can be controlled by the rotation of the stepper motor 208; secondly, by meshing the rack 207 with the toothed ring 209, the push ring plate 201 is kept in a relatively stationary state relative to the plate base 204 when it is not rising or falling.

[0030] Furthermore, a groove 210 is formed in the middle of the push ring plate 201, through which the retaining ring shifting post 401 passes. Sliding grooves 203 are formed on the push ring plates 201 on both sides of the groove 210. A clamping plate 205 is fixedly connected to the plate base 204, and a slider 206 is fixedly connected to the inner side of the clamping plate 205. The push ring plates 201 on both sides of the groove 210 are inserted into the gap between the plate base 204 and the clamping plate 205, and the slider 206 is slidably connected in the sliding groove 203. The rack 207 is located at the opening of the gap between the plate base 204 and the clamping plate 205.

[0031] In this invention, each ring-shifting assembly 200 has a ring-shifting groove 202 on the side of its push-ring plate 201 facing the retaining ring assembly 500. This ring-shifting groove 202 is an arc-shaped groove whose curvature matches the outer circumferential surface of the retaining ring 501. Specifically, the depth of the ring-shifting groove 202 is strictly limited to no more than the axial thickness of a single retaining ring 501. Based on this structure, when the push-ring plate 201 moves towards the retaining ring shifting post 401 under the drive of the stepper motor 208, the gear ring 209, and the rack 207 until the ring-shifting groove 202 coincides with the central axis of the retaining ring assembly 500, due to physical constraints of geometric dimensions, only the single retaining ring 501 located at the very end of the retaining ring assembly 500 can be embedded in the ring-shifting groove 202. The adjacent second retaining ring 501, exceeding the accommodating depth of the ring-shifting groove 202, cannot enter the groove, thus physically achieving forced separation of the end retaining ring 501 from the remaining retaining rings 501. This single-ring receiving structure fundamentally avoids the problems of multiple rejections and incorrect rejections caused by visual judgment errors or improper operation in traditional manual rejection methods. It ensures that each rejection action only acts on the unqualified retaining ring 501 at the end of the retaining ring group 500, effectively preventing qualified retaining rings 501 from being discarded together, and significantly improving the product yield.

[0032] It is worth noting that the push ring plate 201 has a groove 210 in the middle, through which the two retaining ring shifting posts 401 pass. Moreover, when the push ring plate 201 is raised and lowered, the retaining ring shifting posts 401 always pass through the groove 210. The groove 210 can prevent the push ring plate 201 from touching and interfering with the retaining ring shifting posts 401 when it is raised and lowered.

[0033] Furthermore, the translational track assembly 400 includes a clamping claw 405, which is sleeved on the translational slide rail 404 and slides on the translational slide rail 404. The side of the clamping claw 405 facing away from the translational slide rail 404 is fixedly connected to the other end of the plate base 204 away from the stepper motor 208.

[0034] Furthermore, the housing 100 includes a top plate 103, which is fixedly connected to the top of the side plate 101 and the rear plate 108.

[0035] Furthermore, the cutting machine assembly 300 includes a power cord 302, which electrically connects the cutting machine 301 and the power supply box 303. The power supply box 303 is fixedly connected to the top surface of the top plate 103. One end of the cutting machine 301 is fixedly connected to the frame 304. A linear motor 306 is fixedly connected to the bottom of the frame 304. The linear motor 306 is slidably connected to a linear slide rail 305. Both ends of the linear slide rail 305 are fixedly connected to the side of the translation slide rail 404 facing away from the retaining ring shift column 401 and the inner wall of the side plate 101, respectively.

[0036] In this invention, a power switch is provided on the power supply box 303. When the cutting machine 301 is moved to the position directly above the two retaining ring shifting columns 401 by the linear motor 306, and the retaining ring group 500 on the retaining ring shifting column 401 is pushed to the position to be cut, the power switch on the power supply box 303 is turned on, the cutting machine 301 starts, and the rocker plate 402 continues to shake to push the retaining ring group 500 on the retaining ring shifting column 401 to make an opening cut on the retaining ring group 500.

[0037] In this invention, the gripper 405 has an opening on the side facing away from the base plate 204. This opening allows the gripper 405 to move along the translation slide rail 404 and pass through the connection of the linear slide rail 305. The linear slide rail 305 passes through the opening of the gripper 405, so that the sliding of the gripper 405 on the translation slide rail 404 will not come into contact with or interfere with the linear slide rail 305, which is also fixedly connected to the translation slide rail 404. The linear motor 306 is connected to an external power supply and controller.

[0038] It is worth noting that when cutting the retaining ring assembly 500, the linear motor 306 moves on the linear slide rail 305, so that the blade of the cutting machine 301 is located directly above the two retaining ring shifting posts 401, and the plane of the cutting machine 301 blade is parallel to the axis of the two retaining ring shifting posts 401.

[0039] Furthermore, the housing 100 includes an observation plate 105, the two ends of which are fixedly connected to the top of the front plate 102 and the end of the top plate 103 away from the rear plate 108, respectively.

[0040] In this invention, a transparent glass is provided in the middle of the observation plate 105. The operator can observe the specific position of the retaining ring assembly 500 on the retaining ring shifting column 401 through the observation plate 105, thereby determining the timing and duration of operations such as shaking the rocker 402, moving and starting the cutting machine 301, and starting the stepper motor 208 of the shifting ring assembly 200.

[0041] Furthermore, the front panel 102 has an operation notch 1021 located at one end of the front panel 102 near the observation panel 105.

[0042] In this invention, the operation notch 1021 on the front plate 102 makes it easier for the operator to place the snap ring assembly 500 stably on the two snap ring shifting posts 401 for subsequent operations.

[0043] Furthermore, the box body 100 includes box feet 107, and a plurality of box feet 107 are fixedly connected to the bottom surface of the base plate 106.

[0044] In this invention, when it is necessary to process bearing retaining rings 501 with different inner diameters or thicknesses, the operator can replace two retaining ring shifting posts 401 with corresponding spacing according to the actual size of the retaining ring 501 to be processed, so as to adapt to retaining rings 501 with different inner diameters; at the same time, replace the push ring plate 201 with the corresponding groove depth and curvature of the ring shifting groove 202 to adapt to retaining rings 501 with different thicknesses. After the replacement is completed, the feeding, cutting and rejection operations are performed according to the steps of the above embodiment, so as to realize the batch opening processing of retaining rings of multiple sizes and specifications.

[0045] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
