Technical Field
[0001] This application relates to the field of bearing inner ring machining, and in particular to a bearing inner ring grinding device. Background Technology
[0002] The inner ring of the bearing is one of the core components of the rolling bearing. It is mounted on the journal and rotates with the shaft. Its outer surface has grooves to guide the movement of the rolling elements, while its inner surface is a cylindrical hole that is tightly connected to the shaft through an interference fit. To ensure the dimensional accuracy of the bearing inner ring, the grooves and mounting holes of the bearing inner ring need to be ground using grinding equipment before the bearing inner ring is assembled. However, in traditional technology, the grinding process of the groove and the grinding process of the mounting hole are often set up independently. This makes the process switching more troublesome and greatly affects the grinding efficiency of the bearing inner ring.
[0003] Based on this, we propose a bearing inner ring grinding device to solve the above problems. Summary of the Invention
[0004] To address the issue that the grinding processes for the groove and mounting holes are often set up independently, making process switching cumbersome and significantly impacting the grinding efficiency of the bearing inner ring, this application provides a bearing inner ring grinding device.
[0005] The bearing inner ring grinding equipment provided in this application adopts the following technical solution: A bearing inner ring grinding device, comprising: The frame has a support frame fixedly connected to its top, and a feeding box fixedly connected to the top of the support frame. The feeding box has a feed inlet on its top, feeding holes A on both sides of one end of the feeding box, feeding holes B on both sides of the bottom end of the feeding box, and feeding holes C on both sides of the other end of the feeding box. A feeding assembly is assembled inside the feeding box, and a grinding assembly is assembled on one side of the bearing frame. The grinding assembly is used to grind the mounting holes of the bearing inner ring body. A groove grinding mechanism is mounted on the top of the frame near the feed hole A. The groove grinding mechanism is used to grind the grooves of the bearing inner ring body. The feeding assembly is used to cooperate with the feeding box to transfer the bearing inner ring body between the grinding assembly and the groove grinding mechanism.
[0006] By adopting the above technical solution, the controllable rotation of the feeding tray inside the feeding box can realize the sequential transfer of the bearing inner ring body to be ground, which greatly shortens the process change time of the bearing inner ring body and effectively ensures the grinding efficiency of the bearing inner ring body.
[0007] Optionally, the feeding assembly includes: A feeding shaft is rotatably connected to one side of the feeding box. A feeding disc is fixedly connected to one end of the feeding shaft inside the feeding box. The edge of the feeding disc is provided with four receiving grooves for accommodating a single bearing inner ring body. The upright frame is fixedly connected to the top of the support frame. A feeding motor is fixedly connected to the top of the upright frame. A transmission spur gear is fixedly connected to the output end of the feeding motor. A reduction spur gear is fixedly connected to the end of the feeding shaft near the transmission spur gear, and the reduction spur gear is also meshed with the transmission spur gear. An adjusting plate is slidably connected to the side of the upright frame near the feeding box. A hydraulic cylinder is fixedly connected to the upright frame, and the output end of the hydraulic cylinder is also fixedly connected to the adjusting plate. An extension arm A is fixedly connected to the end of the hydraulic cylinder near the feeding hole A, and a support base is fixedly connected to one end of the extension arm A. A positioning component, which is mounted on a support base, is used to position the bearing inner ring body to be grooved and polished. A pusher plate is fixedly connected to one end of an adjusting plate near the feed hole B. A discharge shaft is fixedly connected to one end of the adjusting plate near the feed hole C, and a discharge plate is fixedly connected to one end of the discharge shaft.
[0008] By adopting the above technical solution, the feeding motor is started, which causes the transmission spur gear to drive the reduction spur gear, and then drives the feeding disc to rotate through the feeding shaft. During the rotation of the feeding disc, the feed inlet can be blocked to prevent the bearing inner ring body from continuing to fall. When the feeding shaft drives the feeding disc to rotate to the feeding hole A, the next receiving groove will reach below the feed inlet, and the next bearing inner ring body will fall into the receiving groove and wait for conveying.
[0009] Optionally, the positioning component includes: A hollow shaft is rotatably connected to one end of a support base. A baffle is fixedly connected to one end of the hollow shaft, and multiple positioning rods are slidably connected to one side of the baffle. A guide rod is slidably connected to the middle of the baffle plate. One end of the guide rod is fixedly connected to a guide plate. The outer side of the guide plate is rotatably connected to a linkage rod that corresponds to the positioning rod. The end of the linkage rod away from the guide plate is also rotatably connected to the corresponding positioning rod. An electric actuator is fixedly connected to one end of the extension arm A, and the output end of the electric actuator is rotatably connected to the other end of the guide rod.
[0010] By adopting the above technical solution, the electric push rod is activated to push the guide rod, which causes the guide rod to move the guide plate. Since the linkage rod is connected between the positioning rod and the guide plate, when the position of the guide plate changes, the linkage rod can push the positioning rod, causing the positioning rods to move away from each other. When the positioning rod presses against the inner ring body of the bearing, the positioning of the inner ring body of the bearing can be achieved.
[0011] Optionally, the polishing component includes: A stabilizing plate is fixedly connected to the bottom of one side of the feeding box. A light rod is fixedly connected to the stabilizing plate. A displacement ear is slidably connected to the outside of the light rod. A limit plate is fixedly connected to one end of the displacement ear. A helical spring is fixedly connected to one side of the displacement ear, and the end of the helical spring away from the displacement ear is also fixedly connected to the stabilizing plate. A transmission frame is fixedly connected to the side of the feeding box near the stabilizing plate. A transmission screw is rotatably connected to the inner side of the transmission frame. A transmission motor is fixedly connected to one end of the transmission frame, and the output end of the transmission motor is also fixedly connected to the transmission screw. A push plate is threadedly connected to a transmission screw. A grinding motor is fixedly connected to the top of the push plate, and a grinding head is fixedly connected to the output end of the grinding motor.
[0012] By adopting the above technical solution, before the bearing inner ring body at the feeding hole B moves out of the feeding box, the bearing inner ring body will contact the limiting plate to limit the bearing inner ring body. Finally, the bearing inner ring body will be positioned between the pusher plate and the limiting plate. Then, the drive motor will be started to drive the drive screw to rotate. With the connection between the drive screw and the push plate, the push plate can be adjusted along the drive screw until the grinding head moves into the mounting hole of the bearing inner ring body. At the same time, the grinding motor will be started to drive the grinding head to rotate. Then, through the contact between the grinding head and the mounting hole of the bearing inner ring body, the mounting hole of the bearing inner ring body will be effectively ground.
[0013] Optionally, the groove grinding mechanism includes: A settling seat is fixedly connected to one end of the top of the frame near the feed hole A. A drive shaft is rotatably connected to the top of the settling seat, and a grinding disc is fixedly connected to the outside of the drive shaft. A positioning frame is fixedly connected to the top of the positioning seat. A motor A is fixedly connected to the top of the positioning frame. Pulleys are fixedly connected to the output end of the motor A and the outer side of the transmission shaft. The two pulleys are connected by a transmission belt. A trimming assembly, mounted on the top of the frame, is used to remove the passivation layer from the surface of the grinding disc.
[0014] By adopting the above technical solution, the starting motor B drives the threaded rod to rotate. With the connection between the threaded rod and the bearing seat, the bearing seat and the positioning seat can be adjusted along the threaded rod until the grinding disc contacts the groove of the bearing inner ring body. Then, the starting motor A, under the transmission belt, can drive the grinding disc to rotate through the transmission shaft. As the grinding disc contacts the bearing inner ring body, the groove of the bearing inner ring body can be ground. During the grinding process, the retaining plate can be driven to rotate adaptively under the support of the hollow shaft, thereby changing the contact surface between the bearing inner ring body and the grinding disc.
[0015] Optionally, the trimming component includes: Two mounting bases are fixedly connected to the top of the frame. A threaded rod is rotatably connected between the two mounting bases. One side of one of the threaded rods is fixedly connected to a motor B, and the output end of the motor B is also fixedly connected to the threaded rod. A bearing seat is threaded to the outside of a threaded rod. A motor C is fixedly connected to the top of the bearing seat. A guide seat is fixedly connected to the output end of the motor C. A dressing head is fixedly connected to the middle of the guide seat.
[0016] By adopting the above technical solution, when the application effect of the grinding disc is not good, the motor C is started to drive the guide seat to rotate back and forth, so as to make the dressing head contact the grinding disc, so as to remove the passivation layer of the grinding disc through the dressing head and ensure the dimensional accuracy of the grinding disc.
[0017] Optionally, the top of the feeding box is fixedly connected to a feeding track communicating with the inlet, and the other end of the feeding box is fixedly connected to a discharge track, and the discharge track corresponds to the position of the feeding hole C.
[0018] By adopting the above technical solution, the bearing inner ring body to be ground can be sequentially fed into the receiving groove through the feed port, wait for transfer, and with the setting of the unloading track, it can receive the bearing inner ring body moved out from the feed hole C, and transfer the bearing inner ring body to the collection position or other processes by moving the bearing inner ring body along the unloading track.
[0019] Optionally, a linear groove is provided on the side of the baffle near the positioning rod, and a linear slider is fixedly connected to the positioning rod, and the linear slider is also slidably connected inside the corresponding linear groove.
[0020] By adopting the above technical solution, the displacement of the positioning rod can be effectively guided, avoiding uncontrollable movement of the positioning rod.
[0021] Optionally, a support plate is fixedly connected to the bottom end of the stabilizing plate, and a wear-resistant layer is provided on the support plate.
[0022] By adopting the above technical solution, the bottom of the bearing inner ring body can be supported, preventing the bearing inner ring body from falling between the pusher plate and the limiting plate. In addition, the presence of the wear-resistant layer can also reduce the wear of the pallet and ensure the service life of the pallet.
[0023] Optionally, the diameter of the pulley corresponding to the motor A is smaller than the diameter of the pulley corresponding to the drive shaft.
[0024] By adopting the above technical solution, the rotation speed of the transmission shaft can be effectively controlled, making the grinding disc more stable.
[0025] In summary, this application includes at least one of the following beneficial technical effects: Through the structural coordination of the feeding components, the controllable rotation of the feeding disc inside the feeding box enables the sequential transfer of the bearing inner ring body to be ground, greatly shortening the process changeover time of the bearing inner ring body and effectively ensuring the grinding efficiency of the bearing inner ring body. Through the structural cooperation of the positioning rod, guide plate and linkage rod, the bearing inner ring body can be effectively positioned when grinding the groove of the bearing inner ring body, ensuring that the bearing inner ring body can make stable contact with the grinding plate; Through the structural coordination of the groove grinding mechanism, the main groove of the bearing inner ring can be ground, and the passivation surface of the grinding disc can be eliminated in time, which greatly ensures the application effect of the grinding disc.

The top of the bearing seat 54 is fixedly connected to the motor C55. The output end of the motor C55 is fixedly connected to the guide seat 56. The middle part of the guide seat 56 is fixedly connected to the trimming head 57. In this embodiment, the dressing head 57 can be made of diamond. During the process of the dressing head 57 contacting the grinding disc 46, the passivation layer on the surface of the grinding disc 46 can be removed, the geometric accuracy of the grinding disc 46 can be restored, and the contour shape of the grinding disc 46 can be made in accordance with the processing requirements of the inner ring body 11 groove of the bearing. The implementation principle of a bearing inner ring grinding device in this application embodiment is as follows: First, the bearing inner ring body 11 to be ground is placed on the top of the feeding track 58. With the structural characteristics of the feeding track 58, the bearing inner ring body 11 will move along the feeding track 58 and fall into the interior of one of the receiving grooves 14 through the feed inlet 4. Then the feeding motor 16 is started, which causes the transmission spur gear 17 to move the reduction spur gear 18, and then drives the feeding disc 13 to rotate through the feeding shaft 12. During the rotation of the feeding disc 13, the feed inlet 4 is blocked to prevent the bearing inner ring body 11 from falling further. When the feeding shaft 12 drives the feeding disc 13 to rotate to the feeding hole A5, the next receiving groove 14 will reach below the feed inlet 4, and the next bearing inner ring body 11 will fall into the receiving groove 14 and wait for conveying. Start the hydraulic cylinder 20 to push the adjusting plate 19, so that the extension arm A21 is close to the feed hole A5. As the extension arm A21 is continuously adjusted, the positioning rod 25 will be inserted into the mounting hole of the bearing inner ring body 11. As the baffle 24 contacts the bearing inner ring body 11, the bearing inner ring body 11 is pushed out of the feed box 3 until the groove of the bearing inner ring body 11 corresponds to the grinding disc 46. Then, start the electric push rod 29 to push the guide rod 26, so that the guide rod 26 drives the guide disc 27 to move. Since the linkage rod 28 is connected between the positioning rod 25 and the guide disc 27, when the position of the guide disc 27 changes, the linkage rod 28 can push the positioning rod 25, so that the positioning rods 25 move away from each other. When the positioning rod 25 presses against the bearing inner ring body 11, the positioning of the bearing inner ring body 11 can be achieved. The starting motor B53 drives the threaded rod 52 to rotate. In conjunction with the connection between the threaded rod 52 and the bearing seat 54, the bearing seat 54 and the positioning seat 44 can be adjusted along the threaded rod 52 until the grinding disc 46 contacts the groove of the bearing inner ring body 11. Then, the starting motor A48, under the transmission of the transmission belt 50, can drive the grinding disc 46 to rotate through the transmission shaft 45. As the grinding disc 46 contacts the bearing inner ring body 11, the groove of the bearing inner ring body 11 can be ground. During the grinding process, the baffle 24 can be driven to rotate adaptively under the support of the hollow shaft 23, thereby changing the contact surface between the bearing inner ring body 11 and the grinding disc 46. When the application effect of the grinding disc 46 is not good, the motor C55 is started to drive the guide seat 56 to rotate back and forth, so that the dressing head 57 contacts the grinding disc 46, so as to remove the passivation layer of the grinding disc 46 through the dressing head 57 and ensure the dimensional accuracy of the grinding disc 46. After the inner ring body 11 of the bearing is ground, the hydraulic cylinder 20 pulls the adjusting plate 19, causing the inner ring body 11 of the bearing to retract into the inside of the receiving groove 14, and the positioning rod 25 moves out of the inside of the receiving groove 14. Then, the feeding motor 16 is started to drive the feeding plate 13 to rotate ninety degrees again, so that the inner ring body 11 of the bearing after the groove is ground reaches the position of the feeding hole B6, and so that the next inner ring body 11 of the bearing reaches the position of the feeding hole A5. Then, the hydraulic cylinder 20 is activated to push the adjusting plate 19 to adjust, so that the baffle 24 pushes the bearing inner ring body 11 at the feeding hole A5 out of the feeding box 3. At the same time, the pushing plate 30 pushes the bearing inner ring body 11 at the feeding hole B6 out of the feeding box 3. Before the bearing inner ring body 11 at the feeding hole B6 moves out of the feeding box 3, the bearing inner ring body 11 will contact the limiting plate 36 to limit the bearing inner ring body 11. Finally, the bearing inner ring body 11 is positioned between the pushing plate 30 and the limiting plate 36. Then, the transmission motor 40 is activated to drive the transmission screw 39 to rotate. With the connection between the transmission screw 39 and the pushing plate 41, the pushing plate 41 can be adjusted along the transmission screw 39 until the grinding head 43 moves into the mounting hole of the bearing inner ring body 11. At the same time, the grinding motor 42 is activated to drive the grinding head 43 to rotate. Then, through the contact between the grinding head 43 and the mounting hole of the bearing inner ring body 11, the mounting hole of the bearing inner ring body 11 is effectively ground. After the mounting holes of the bearing inner ring body 11 are ground, the hydraulic cylinder 20 is activated to pull the adjusting plate 19 to adjust it away from the feeding box 3, so that the bearing inner ring body 11 at the baffle 24 and the push plate 30 are both retracted into the corresponding receiving groove 14. Since the displacement ear 35 can be stretched when it is displaced, the bearing inner ring body 11 can be supported by the continuous contact between the limiting plate 36 and the bearing inner ring body 11 during the retraction process. Restart the feeding motor 16, causing the transmission spur gear 17 to engage the reduction spur gear 18, causing the feeding disc 13 to rotate 90 degrees again, so that the bearing inner ring body 11 after the mounting hole grinding reaches the feeding hole C7, and the bearing inner ring body 11 after the groove grinding reaches the feeding hole B6. During the subsequent adjustment process of the adjustment plate 19, the bearing inner ring body 11 will be pushed out of the feeding box 3 from the feeding hole C7 through the contact between the feeding disc 32 and the bearing inner ring body 11, and sent to the collection position through the feeding track 59.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
