Description

Technical Field

[0001] The invention relates to the technical field of ring grinding, in particular to a rolling bearing ring processing device and method. Background Art

[0002] The ring is an important part of the rolling bearing. When producing and processing the ring, it is necessary to first select the required cylindrical metal tube material, and then cut the selected cylindrical tube material according to the designed size. The cut metal tube material is processed by hot forging or cold forging to eliminate the inherent defects of the metal and improve the metal structure; the forged blank is then annealed or normalized to adjust the metal structure and properties; the blank is then turned on a lathe to remove excess metal and form a preliminary ring shape; and the turned ring is quenched and tempered to improve its hardness and toughness; the quenched and tempered ring needs to be ground to achieve the required accuracy and surface quality; finally, it is inspected, demagnetized and cleaned; the finished ring is obtained;

[0003] After the ring undergoes heat treatment processes such as quenching and tempering, the release of internal stress or uneven cooling of the ring material will cause the ring to warp or deform to a certain extent; grinding can correct these deformations and ensure that the bearing ring has good position tolerances such as roundness and coaxiality; in addition, grinding can significantly improve the surface finish of the ring and reduce surface roughness; this is very important for reducing the friction coefficient of the rolling bearing during operation, reducing wear and extending the service life;

[0004] The existing grinding methods of bearing rings are mainly divided into three types: end face grinding, internal grinding and external grinding. For external grinding, it is mostly processed in batches by centerless external grinding machines; while end face grinding and internal grinding are limited by geometric shapes and can only be processed in single pieces;

[0005] Since end face grinding is performed on the end face of the bearing ring, the ring must remain stable during the grinding process without deviation or vibration; therefore, the clamping method usually requires the inner diameter or outer diameter of the single ring to be fixed to ensure the flatness and verticality of the end face; while internal cylindrical grinding mainly grinds the inner diameter surface of the bearing ring, which requires the ring to be accurately positioned during grinding to ensure the dimensional accuracy and roundness of the inner diameter; therefore, the clamping method needs to ensure the stability of the inner hole position of the single ring during the grinding process;

[0006] As a result, each grinding method has different requirements for clamping, which requires multiple clamping and switching of the bearing ring. Each clamping will introduce new positioning errors, resulting in deviations between the relative position relationship of each reference surface and the ideal state during the actual processing, affecting the final processing accuracy and matching accuracy. In addition, multiple clamping and repositioning processes will consume more time, reducing the production efficiency of the ring grinding process.

[0007] In view of this, in order to overcome the above technical problems, the present invention proposes a rolling bearing ring processing device and method to solve the above technical problems. Summary of the invention

[0046] The inner ring grinding unit is installed in the second grinding groove 23; the inner ring grinding unit is used for grinding the inner ring of the ferrule.

[0047] As an embodiment of the present invention, a groove 16 is provided at the upper end of the body 1; a grinding wheel 161 is rotatably connected in the groove 16; a gear ring 142 is fixedly connected to the surface of the rotating rod 14; a gear shaft 17 meshing with the gear ring 142 is rotatably connected inside the body 1; the gear shaft 17 and the grinding wheel 161 are connected by a belt drive through a transmission belt 171;

[0048] An electromagnetic plate 221 and a mounting spring 222 are installed in the groove 16 and the first grinding groove 22; the two electromagnetic plates 221 are respectively embedded in the bottom of the groove 16 and the bottom of the first grinding groove 22; the two mounting springs 222 are respectively connected to the grinding wheel 161 and the transmission rod 21.

[0049] As an embodiment of the present invention, the No. 1 grinding groove 22, the No. 2 grinding groove 23 and the groove 16 are all slidably connected with a rotating ring 24; the rotating ring 24 located in the No. 1 grinding groove 22 and the No. 2 grinding groove 23 is slidably connected to the transmission rod 21; the rotating ring 24 located in the groove 16 is slidably connected to the grinding wheel 161; the rotating rod 14 is connected to the No. 1 grinding groove 22 and the No. 2 grinding groove 23 rotating ring 24 by belt transmission through a belt 141; the gear shaft 17 is connected to the rotating ring 24 of the groove 16 by belt transmission through a transmission belt 171;

[0050] The No. 1 grinding groove 22, the No. 2 grinding groove 23 and the groove 16 are all arranged in an arc shape; a No. 1 fan-shaped groove 223 connected to the No. 1 grinding groove 22 and the No. 2 grinding groove 23 is opened inside the mounting plate 2; a No. 2 fan-shaped groove 162 connected to the groove 16 is opened inside the body 1; the gear shaft 17 is rotatably connected to the No. 2 fan-shaped groove 162; reset units are installed in the No. 1 grinding groove 22, the No. 2 grinding groove 23 and the groove 16.

[0051] As an embodiment of the present invention, the reset unit includes a reset plate 25; the reset plate 25 is configured to be arc-shaped; the arc-shaped convex surface of the reset plate 25 contacts the rotating ring 24; one end of the reset plate 25 away from the rotating ring 24 is fixedly connected to a reset spring 251 connected to the groove wall;

[0052] During operation, it is difficult to achieve accurate processing of all these surfaces on one grinder or workstation because each grinding method has different requirements for clamping. This requires multiple clamping and switching of the bearing ring, and each clamping will introduce new positioning errors, which will cause the relative position relationship of each reference surface to deviate from the ideal state during actual processing, affecting the final processing accuracy and matching accuracy. In addition, multiple clamping and repositioning processes will consume more time, reducing the production efficiency of the ring grinding process.

[0053] In this regard, the present invention provides a grinding groove at the lower end of the mounting plate 2, so that when the mounting plate 12 pushes the ferrule to the first grinding groove 22 and the second grinding groove 23, the transmission rod 21 in the first grinding groove 22 can grind the end face of the ferrule through the grinding disc 211, and then the inner ring grinding unit in the second grinding groove 23 can grind the inner ring wall of the ferrule. On the one hand, there is no need to clamp and switch the ferrule, thereby reducing the influence of positioning errors and improving the processing accuracy and matching accuracy of the ferrule. On the other hand, the time consumed by clamping and switching is reduced, thereby improving the production efficiency of the ferrule grinding process.

[0054] In the initial state, the conveyor belt for conveying the ferrules from the outside is directly opposite to the feed port 111 on one side of the machine body 1; the ferrules processed in batches by the centerless cylindrical grinder are sequentially conveyed to the feed port 111 via the conveyor belt, so that the ferrules enter the installation groove 11 through the feed port 111. Since the installation groove 11 is rotatably connected with the installation disk 12, the ferrules entering the installation groove 11 will be blocked by the installation disk 12; at this time, the drive motor 13 is controlled to run, so that the drive motor 13 can drive the worm wheel ring 122 to rotate through the worm 131 The worm gear ring 122 drives the mounting plate 12 fixed thereto to rotate, so that the mounting plate 12 drives the U-shaped groove 121 on the edge to rotate until the U-shaped groove 121 faces the feed port 111. At this time, the ring blocked by the mounting plate 12 will be pushed into the U-shaped groove 121 by the ring on the rear conveyor belt, so that the mounting plate 12 drives the ring entering the U-shaped groove 121 to rotate synchronously, so that the ring entering the U-shaped groove 121 moves toward the direction close to the first grinding groove 22 under the push of the mounting plate 12; at this time, the first grinding groove The electromagnetic plate 221 in the groove 16 is in a powered state, so that the transmission rod 21 in the first grinding groove 22 is attracted by the electromagnetic plate 221 to squeeze the installation spring 222 in the first grinding groove 22, so that the transmission rod 21 in the first grinding groove 22 moves toward the bottom of the first grinding groove 22; and the grinding wheel 161 in the groove 16 is attracted by the electromagnetic plate 221 at the bottom of the groove 16 and squeezes the installation spring 222 in the groove 16 to move toward the bottom of the groove 16, so that the grinding wheel 161 in the groove 16 is attracted by the electromagnetic plate 221 at the bottom of the groove 16 and squeezes the installation spring 222 in the groove 16 to move toward the bottom of the groove 16, so that the grinding wheel 161 in the first grinding groove 22 The transmission rod 21 and the grinding wheel 161 in the groove 16 move away from each other. At this time, the transmission rod 21 in the first grinding groove 22 slides upward relative to the rotating ring 24 slidably connected thereto, and the grinding wheel 161 in the groove 16 slides downward relative to the rotating ring 24 connected thereto. At this time, the grinding wheel 161 is located in the groove 16, and the mounting plate 12 rotates above the grinding wheel 161, so that the grinding wheel 161 does not enter the mounting groove 11, so as to prevent the grinding wheel 161 from blocking the rotating mounting plate 12.

[0055] When the ring is pushed by the mounting plate 12 and is located between the grinding wheel 161 and the transmission rod 21 in the first grinding groove 22, the first grinding groove 22 and the electromagnetic plate 221 in the groove 16 are de-energized, so that the grinding wheel 161 and the transmission rod 21 in the first grinding groove 22 are respectively pushed by the squeezed mounting spring 222 to move toward each other, so that the transmission rod 21 in the first grinding groove 22 pushes the grinding disc 211 connected thereto to descend and contact the upper end surface of the mounting plate 12, and the grinding wheel 161 in the groove 16 is pushed by the mounting spring 222 in the groove 16. 22 pushes the grinding wheel 161 into the U-shaped groove 121 and pushes the ring upward. At this time, the grinding wheel 161 in the first grinding groove 22 and the grinding wheel 161 in the groove 16 are located in the same U-shaped groove 121. The ferrule is located between the grinding disc 211 and the grinding wheel 161, so that the grinding disc 211 and the grinding wheel 161 clamp the ferrule; at the same time, the servo motor 15 is controlled to operate so that the servo motor 15 can drive the rotating rod 14 to rotate, so that the rotating rod 14 drives the rotating ring 24 connected to the transmission rod 21 with a belt transmission to rotate through the belt 141, so that the rotating ring 24 in the first grinding groove 22 drives the transmission rod 21 slidably connected thereto to rotate, so that the transmission rod 21 drives the grinding disc 211 fixed at the lower end to rotate; at the same time, the rotating rod 14 drives the surface fixed The gear ring 142 rotates, so that the gear ring 142 drives the gear shaft 17 meshing with it to rotate in the opposite direction; since the gear shaft 17 and the rotating ring 24 in the groove 16 are connected by a belt drive through the transmission belt 171, the gear shaft 17 drives the grinding wheel 161 to rotate synchronously through the rotating ring 24 in the groove 16. At this time, the grinding wheel 161 and the grinding disc 211 rotate in opposite directions, so that the grinding wheel 161 and the grinding disc 211 rotating in opposite directions can effectively grind the upper end face and the lower end face of the ring, thereby realizing grinding and polishing of the end face of the ring;

[0056] Since the No. 1 grinding groove 22 and the groove 16 are both set to an arc shape, when the grinding wheel 161 and the grinding disc 211 perform end surface grinding on the ring in the U-shaped groove 121, the mounting plate 12 is still in a rotating state driven by the driving motor 13, so that the mounting plate 12 can push the grinding wheel 161 and the grinding disc 211 in the U-shaped groove 121 to rotate synchronously, so that the grinding wheel 161 drives the rotating ring 24 slidably connected thereto to rotate in the arc-shaped groove 16, and the grinding disc 211 drives the rotating ring 24 in the No. 1 grinding groove 22 to move in the No. 1 grinding groove 22 through the transmission rod 21 fixedly connected thereto, and the end of the mounting spring 222 in the No. 1 grinding groove 22 away from the transmission rod 21 is in sliding contact with the groove bottom of the No. 1 grinding groove 22, and the mounting spring 222 in the groove 16 is away from the grinding wheel 16. One end of the reset plate 25 is in sliding contact with the bottom of the groove 16; the two rotating rings 24 move in the No. 1 grinding groove 22 and the groove 16 respectively, and at this time, the two rotating rings 24 push the reset units in contact with them respectively, that is, the two rotating rings 24 in the No. 1 grinding groove 22 and the groove 16 respectively push the reset plate 25 in contact with them to squeeze the reset spring 251 connected to the reset plate 25 to move toward the No. 1 grinding groove 22 or the groove 16 close to the No. 2 grinding groove 23; because the reset plate 25 is set in an arc shape, the reset plate 25 and the rotating ring 24 are in point contact, thereby reducing the friction between the reset plate 25 and the rotating ring 24, and at the same time, the reset plate 25 is set to be made of PTFE material, so that the reset plate 25 made of PTFE material has the characteristics of a smooth surface, further reducing the reset The friction between the plate 25 and the swivel 24 can reduce the friction damage caused by the swivel 24 to the reset plate 25, thereby improving the service life of the reset plate 25; the arrangement of the No. 1 sector groove 223 and the No. 2 sector groove 162 is to facilitate the movement of the belt 141 and the transmission belt 171, to ensure that the swivel 24 in the No. 1 grinding groove 22 can be effectively connected to the rotating rod 14 through the belt 141, and the swivel 24 in the groove 16 can be effectively connected to the gear shaft 17 through the transmission belt 171; when the ring in the U-shaped groove 121 is polished, the swivel 24 is close to the other end of the No. 1 grinding groove 22, and the electromagnetic plate 221 is energized so that the electromagnetic plate 221 can absorb the transmission rod 21 in the No. 1 grinding groove 22 to drive The grinding disc 211 extends upwardly out of the U-shaped groove 121, and the electromagnetic plate 221 in the groove 16 attracts the grinding wheel 161 and extends downwardly out of the U-shaped groove 121, so that the mounting plate 12 no longer drives the grinding wheel 161 and the grinding disc 211 to move, so that the grinding wheel 161 and the grinding disc 211 no longer push the reset spring 251 through the rotating ring 24 connected thereto, so that the reset plate 25 pushed by the restoring force of the reset spring 251 can push the rotating ring 24 in contact therewith to move away from the second grinding groove 23, so that the transmission rod 21 in the first grinding groove 22 drives the grinding disc 211 to reset, and the grinding wheel 161 in the groove 16 is also reset by the push of the reset plate 25, and then the mounting plate 12 drives the next ferrule through the U-shaped groove 121 to perform a new round of end face grinding;When the end surface grinding of the ferrule is completed and it passes through the first grinding groove 22, the mounting plate 12 drives the ferrule with the end surface grinding completed to the second grinding groove 23 through the U-shaped groove 121, so that the inner ring grinding unit in the second grinding groove 23 can grind the inner ring of the ferrule. ;

[0057] As an embodiment of the present invention, the inner ring grinding unit includes a T-rod 231; a connecting groove 232 is provided at the lower end of the transmission rod 21 in the No. 2 grinding groove 23; the T-rod 231 is slidingly sealed and connected in the connecting groove 232; the T-rod 231 and the bottom of the connecting groove 232 are connected by a support spring 233; an electromagnetic sheet 234 is inlaid at the bottom of the connecting groove 232; grinding blocks 235 are installed at both ends of the T-rod 231; and an inclined groove 18 connected to the mounting groove 11 is provided on one side of the body 1.

[0058] As an embodiment of the present invention, rectangular grooves 236 are provided at the two opposite ends of the T-bar 231; the grinding block 235 is slidingly sealed and connected in the rectangular groove 236; the lower end of the T-bar 231 is provided with a circular groove 26 connected to the rectangular groove 236; the circular groove 26 is internally threaded with a sealing rod 261; and the lower end of the sealing rod 261 is provided with a straight groove 262.

[0059] As an embodiment of the present invention, both sides of the groove wall facing the U-shaped groove 121 of the mounting plate 12 are provided with slots 123; an electric push rod 124 is fixedly installed inside the slot 123; a clamping block 125 is fixedly connected to one end of the electric push rod 124 away from the bottom of the slot 123;

[0060] During operation, when the ferrule has completed end surface grinding and passed through the No. 1 grinding groove 22, the mounting plate 12 drives the ferrule that has completed end surface grinding to move toward the No. 2 grinding groove 23 through the U-shaped groove 121. Before the mounting plate 12 drives the ferrule to the No. 2 grinding groove 23 through the U-shaped groove 121, the electromagnetic sheet 234 in the No. 2 grinding groove 23 is always in a powered state, so that the electromagnetic sheet 234 can absorb the T-shaped rod 231 and squeeze the supporting spring 233 into the connecting groove 232, so as to prevent the T-shaped rod 231 from being inserted into the U-shaped groove 121 of the mounting plate 12 where no ferrule is installed, and to prevent the T-shaped rod 231 from blocking the mounting plate 12 in the mounting groove 11 from rotating due to being inserted into the U-shaped groove 121 where no ferrule is installed. This ensures that the mounting plate 12 can operate stably. When the mounting plate 12 drives the end-surface-grinded ferrule to the second grinding groove 23 through the U-shaped groove 121, the electromagnetic plate 234 is powered off, so that the T-shaped rod 231 in the connecting groove 232 is pushed by the supporting spring 233 and extends out of the connecting groove 232, so that the lower end surface of the T-shaped rod 231 contacts the upper end surface of the mounting plate 12. As the mounting plate 12 drives the ferrule in the U-shaped groove 121 to rotate to face the T-shaped rod 231, the T-shaped rod 231 is located directly above the ferrule. At this time, the T-shaped rod 231 is pushed by the supporting spring 233 to enter the ferrule of the U-shaped groove 121. At the same time, the slots 1 on both sides of the U-shaped groove 121 are first controlled. The electric push rods 124 in 23 are running, so that the two electric push rods 124 push the clamping blocks 125 connected thereto to extend out of the slot 123, so that the clamping blocks 125 are in contact with the ferrule; since the clamping blocks 125 are made of fluororubber material, the clamping blocks 125 have good elasticity, wear resistance and friction coefficient; when the two electric push rods 124 push the two connected clamping blocks 125 to clamp the ferrule, the clamping blocks 125 are squeezed by the electric push rods 124 and the ferrule and deformed, so that the deformed clamping blocks 125 can fit on the surface of the ferrule, so that the friction between the clamping blocks 125 and the ferrule is increased, thereby improving the clamping effect of the clamping blocks 125 on the ferrule; when the T-bar 231 is fully inserted into the ferrule After the inner ring of the ferrule, the T-shaped rod 231 drives the two grinding blocks 235 to enter the ferrule, so that the two grinding blocks 235 can contact the inner ring wall of the ferrule, and the grinding disc 211 and the grinding wheel 161 in the rear grinding groove 22 are also inserted into the corresponding U-shaped groove 121; because there are two belts 141, the rotating rod 14 drives the two rotating rings 24 in the No. 1 grinding groove 22 and the No. 2 grinding groove 23 to rotate respectively through the two belts 141; and there are two No. 1 fan-shaped grooves 223, and the two belts 141 move in the two No. 1 fan-shaped grooves 223 respectively; to ensure that the two belts 141 can normally and stably drive the rotating rings 24 in the No. 1 grinding groove 22 and the No. 2 grinding groove 23 to rotate respectively;At this time, the servo motor 15 is controlled to run, so that in the process of driving the grinding disc 211 and the grinding wheel 161 to rotate, the servo motor 15 can also drive the rotating ring 24 in the second grinding groove 23 to rotate through the rotating rod 14, so that the rotating ring 24 in the second grinding groove 23 drives the transmission rod 21 slidably connected thereto to rotate, so that the transmission rod 21 can drive the T-bar 231 to rotate synchronously, so that the T-bar 231 can drive the two grinding blocks 235 to rotate synchronously, and the outer wall of the ferrule is clamped by the clamping block 125, so that the two grinding blocks 235 can effectively rotate and rub with the inner ring wall of the ferrule during the rotation process, thereby effectively grinding the inner ring of the ferrule;

[0061] Since different mechanical designs and application scenarios have different requirements for the size and performance of bearings, that is, the rings with the same outer diameter may also be designed with different inner diameters to meet the needs of different application scenarios; therefore, when grinding the inner rings of the rings with different inner diameters, it is necessary to replace the T-shaped rods 231 of different models to facilitate effective grinding of the inner rings of the rings with different inner diameters. However, the replacement of the T-shaped rods 231 will not only consume more time and reduce the production efficiency of the ring grinding process; and the use of different models of T-shaped rods 231 will also increase the purchase and maintenance costs of the T-shaped rods 231, thereby increasing the production cost of the ring grinding process;

[0062] In this regard, the present invention provides a sealing rod 261. The user rotates the sealing rod 261 so that the sealing rod 261 spirally enters the circular groove 26 and can squeeze the hydraulic oil in the circular groove 26 into the rectangular groove 236, so that the grinding block 235 in the rectangular groove 236 is pushed by the hydraulic oil and extends out of the rectangular groove 236, so that the distance between the two grinding blocks 235 facing the T-shaped rod 231 is increased, so that the two grinding blocks 235 can grind the inner ring of the ring with a larger diameter, so that there is no need to replace different types of T-shaped rods 231, which greatly reduces the purchase and maintenance costs of different types of T-shaped rods 231, and further reduces the production cost of the ring grinding process; at the same time, it also reduces the replacement time of the T-shaped rod 231, and improves the production efficiency of the ring grinding process; so that the practicality of the present invention is effectively improved;

[0063] In the initial state, the mounting plate 2 is fixedly connected to the machine body 1 by bolts. When the distance between the two grinding blocks 235 of the T-bar 231 needs to be adjusted, the mounting plate 2 needs to be removed first, and a flat-blade screwdriver needs to be inserted into the slot 262 at the lower end of the sealing rod 261. Then, the user rotates the flat-blade screwdriver so that the flat-blade screwdriver inserted into the slot 262 can push the sealing rod 261 to rotate through the slot wall of the slot 262. When the distance between the two grinding blocks 235 needs to be increased, it is only necessary to rotate the sealing rod 261 into the circular groove 26 for spiral rotation, so that the sealing rod 261 pushes the hydraulic oil in the circular groove 26 into the rectangular groove 236, so that the hydraulic oil entering the rectangular groove 236 pushes the grinding block 235 out of the rectangular groove 236, so that the distance between the two grinding blocks 235 increases. If the distance between the two grinding blocks 235 needs to be reduced, it is only necessary to rotate the sealing rod 261 in the opposite direction. The sealing rod 261 is spirally extended out of the circular groove 26, so that the space in the circular groove 26 is increased, so that the hydraulic oil in the rectangular groove 236 flows back into the circular groove 26, so that the grinding block 235 in the rectangular groove 236 enters the rectangular groove 236 under the effect of negative pressure adsorption, so that the distance between the two grinding blocks 235 is reduced; by adjusting the distance between the grinding blocks 235, the distance between the two ends of the two grinding blocks 235 that are far away from each other is the diameter length of the inner ring of the ring, so that the grinding block 235 can effectively grind the inner ring of the ring with different diameter lengths, so that there is no need to replace the T-bar 231, which greatly reduces the purchase and maintenance costs of different models of T-bars 231, and thus reduces the production cost of the ring grinding process; at the same time, it also reduces the replacement time of the T-bar 231, and improves the production efficiency of the ring grinding process; so that the practicality of the present invention is effectively improved;

[0064] Moreover, when the mounting plate 12 pushes the ferrule to move, the ferrule drives the transmission rod 21 in the No. 2 grinding groove 23 to move synchronously through the T-bar 231, so that the transmission rod 21 in the No. 2 grinding groove 23 drives the swivel 24 slidably connected thereto to move in the No. 2 grinding groove 23, so that the swivel 24 in the No. 2 grinding groove 23 pushes the reset plate 25 in contact with it to squeeze the reset spring 251. At the same time, the electromagnetic sheet 234 is controlled to be energized, and at this time, the current passed through the electromagnetic sheet 234 is continuously increased, so that the adsorption force generated by the electromagnetic sheet 234 on the T-bar 231 is continuously increased, so that the T-bar 231 is adsorbed by the electromagnetic sheet 234 and moves slowly upward, so that the slowly moving T-bar 231 can continuously grind the inner ring wall of the ferrule above it, thereby increasing the grinding area of ​​the inner ring wall of the ferrule by the T-bar 231, and ensuring that the inner ring wall of the ferrule is uniformly polished. Effective grinding is performed until the T-bar 231 completes the grinding of the inner ring wall of the ring, and the electromagnetic sheet 234 absorbs the T-bar 231 and completely enters the connecting groove 232, so that the T-bar 231 is located at the upper end surface of the U-shaped groove 121 at this time. At this time, the T-bar 231 is no longer pushed by the U-shaped groove 121, so that the reset spring 251 pushes the T-bar 231 to reset through the reset plate 25; so that the T-bar 231 performs a new round of inner ring grinding on the next ring; then the mounting plate 12 pushes the ground ring in the U-shaped groove 121 to move in the direction of the inclined groove 18 until the ring is above the inclined groove 18, and the ring will fall into the inclined groove 18 under the action of gravity, so that the ring falling into the inclined groove 18 will slide out of the machine body 1 along the inclined surface of the inclined groove 18, so the user only needs to place a collection box at the notch of the inclined groove 18 to collect the ground ring.

[0065] A rolling bearing ring processing method, which is applicable to the above-mentioned rolling bearing ring processing device, and the steps of the method are as follows:

[0066] S1: Select the required cylindrical metal tube material and obtain the ring with the required hardness and toughness through cutting, hot forging, normalizing, turning, quenching and tempering;

[0067] S2: After the quenched and tempered ferrule is cooled, it is transported to the installation groove 11 through the conveyor belt through the feed port 111 of the machine body 1, and then the driving motor 13 drives the installation plate 12 to push the ferrule entering the installation groove 11 into the No. 1 grinding groove 22 through the U-shaped groove 121. At this time, the servo motor 15 drives the grinding wheel 161 and the grinding disc 211 to rotate through the rotating rod 14, so that the grinding disc 211 in the No. 1 grinding groove 22 and the grinding wheel 161 in the lower groove 16 and the ferrule in the U-shaped groove 121 perform end surface grinding;

[0068] S3: When the end surface of the ferrule is polished, the compressed reset spring 251 pushes the rotating ring 24 in the first grinding groove 22 and the groove 16 through the reset plate 25 to respectively drive the grinding disc 211 and the grinding wheel 161 connected thereto to reset, and then controls the electric push rod 124 in the U-shaped groove 121 to push the clamping block 125 to clamp the end surface polished ferrule; until the clamped ferrule moves to the second grinding groove 23, controls the T-shaped rod 231 to drive the grinding block 235 to insert into the ferrule in the U-shaped groove 121, so that the T-shaped rod 231 grinds the inner ring wall of the ferrule through the grinding block 235;

[0069] S4: When the distance between the grinding blocks 235 needs to be adjusted, the mounting plate 2 is first removed, and the sealing rod 261 is rotated with a flat screwdriver so that the sealing rod 261 enters and exits the circular groove 26, such as rotating the sealing plate into the circular groove 26; so that the sealing plate can push the hydraulic oil in the circular groove 26 into the two rectangular grooves 236 facing each other, so that the grinding blocks 235 in the rectangular grooves 236 extend out of the rectangular grooves 236, so that the distance between the two grinding blocks 235 increases;

[0070] S5: After the ring has completed the grinding process and passed the second grinding groove 23, the mounting plate 12 will continue to drive the ring in the U-shaped groove 121 to the inclined groove 18, and the ring will fall into the inclined groove 18 under the action of gravity, so that the ring falling into the inclined groove 18 will slide along the inclined surface of the groove and fall into the collection box placed at the notch of the inclined groove 18;

[0071] S6: Finally, the user inspects, demagnetizes and cleans the ferrules collected in the collection box, and obtains the desired finished ferrules.
