Description
Technical Field
[0001] This invention relates to the field of roller processing technology, specifically to a grinding device for bearing roller processing. Background Technology
[0002] As a key component in mechanical equipment, the performance and quality of bearings directly affect the operating efficiency and lifespan of the equipment. In the bearing manufacturing process, rollers, as one of the core components, are of paramount importance in terms of precision and surface quality. Grinding, as a key process in roller processing, not only ensures the dimensional and shape accuracy of the rollers but also improves their surface quality, thereby enhancing the overall performance of the bearing.
[0003] When grinding tapered rollers using a grinding device, one side of the device has a high-speed rotating grinding wheel, and the other side has a low-speed rotating guide wheel. The tapered roller is pushed into the grinding station between the grinding wheel and the guide wheel. Then, relying on the combined action of the high-speed grinding wheel and the low-speed guide wheel, the roller is driven to rotate through friction, simultaneously completing the grinding of its outer diameter, thus achieving the grinding process. However, during the grinding of tapered rollers, the speed ratio between the grinding wheel and the guide wheel is maintained within a set range to ensure the grinding quality. But the set range for the speed ratio between the grinding wheel and the guide wheel cannot be precisely controlled. The automatic adjustment is based on the diameter and length of the tapered roller. For large-diameter rollers, maintaining a high guide wheel speed (i.e., low speed ratio) will cause the roller to experience large centrifugal vibration in the grinding zone, making it impossible to guarantee roundness. For longer rollers, the contact area with the guide wheel is larger, resulting in greater frictional resistance torque. Maintaining a high guide wheel speed (i.e., low speed ratio) will cause the long roller to slip at high speeds, affecting the synchronization and stability of the long roller's rotation, thus impacting the grinding quality. Therefore, we propose a bearing roller grinding device. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1 Please see Figures 1 to 11 The present invention provides a technical solution: a bearing roller grinding device, comprising: a device body 11, on which a guide wheel 12 and a grinding wheel 13 are provided; It also includes: a feeding assembly 2, which is disposed on the upper side of the device body 11. The feeding assembly 2 is used to push the roller to the grinding area between the grinding wheel 13 and the guide wheel 12 and to detect the diameter of the roller. The initial control component 3 is located on one side of the device body 11. The initial control component 3 adjusts the rotation speed of the guide wheel 12 based on the roller diameter detected by the feeding component 2. Correction component 4 is located on one side of the initial control component 3. Correction component 4 is used to detect the length of the roller and correct the rotation speed of the guide wheel 12 adjusted by the initial control component 3 according to the detected roller length. Adjustment component 5 is located on one side of the initial control component 3. Adjustment component 5 automatically adjusts the speed ratio setting range of grinding wheel 13 and guide wheel 12 according to the diameter and length of the roller.
[0020] When the conical roller is ground by the grinding device body 11, the feeding component 2 pushes the roller into the grinding area between the grinding wheel 13 and the guide wheel 12. Then, by controlling the rotation of the guide wheel 12, the roller can be driven to rotate, and the roller is ground by the high-speed rotating grinding wheel 13. The feeding component 2 can simultaneously detect the diameter at both ends of the roller. The initial control component 3 can initially adjust the rotation speed of the guide wheel 12 according to the roller diameter detected by the feeding component 2. The correction component 4 can further correct the rotation speed of the guide wheel 12 according to the roller length detected, thereby adjusting the rotation speed of the guide wheel 12. At the same time, the adjustment component 5 can automatically adjust the speed ratio setting range of the grinding wheel 13 and the guide wheel 12 according to the detected roller diameter and length. By comparing the actual speed ratio of the grinding wheel 13 and the guide wheel 12 with the setting range, the rotation speed of the guide wheel 12 is adjusted again to keep the speed ratio of the grinding wheel 13 and the guide wheel 12 within the set range to ensure the quality of roller grinding.
[0021] The feeding assembly 2 includes a support frame 21 fixedly connected to the upper side of the device body 11. A bracket 22 is fixedly connected to the upper side of the support frame 21. A push electric push rod 24 is fixedly connected to one side of the support frame 21. A slide rod 23 is fixedly connected to the telescopic end of the push electric push rod 24 and slides through the support frame 21.
[0022] A fixing member 25 is fixedly connected to the slide rod 23. A dual-axis electric actuator 26 is fixedly connected to the upper inside of the fixing member 25. The two telescopic ends of the dual-axis electric actuator 26 are respectively fixedly connected to the mounting member 27 which is slidably disposed with the slide rod 23. A connecting member 28 is fixedly connected to the lower side of the mounting member 27.
[0023] The inner side of the mounting component 27 is fixedly connected to the detection electric actuator 1 29 and the detection electric actuator 217. The telescopic end of the detection electric actuator 1 29 is fixedly connected to the connecting rod 1 210. The connecting rod 211 is provided on the lower side of the connecting rod 1 210. The telescopic end of the detection electric actuator 217 is fixedly connected to the connecting rod 3 212. The connecting rod 4 213 is provided on the lower side of the connecting rod 3 212. The lower ends of the connecting rod 211 and the connecting rod 4 213 pass through the connecting component 28 and can move up and down.
[0024] Ball bearings 214 are respectively installed on the lower side of connecting rod 211 and the upper side of connecting rod 4 213. Pressure sensors 215 are respectively installed inside the lower side of connecting rod 1 210 and the lower side of connecting rod 3 212. The upper side of connecting rod 211 abuts against the pressure sensor 215 on the lower side of connecting rod 1 210, which can detect the pressure value of connecting rod 211. The lower side of the upper part of connecting rod 4 213 abuts against the pressure sensor 215 inside the lower side of connecting rod 3 212, which can detect... The pressure value of connecting rod 4 213 is determined by distance sensor 1 216 and distance sensor 2 218, which are provided on one side of connecting rod 2 211. Both distance sensor 1 216 and distance sensor 2 218 correspond to the upper side of the protruding part on the lower side of connecting rod 3 212. Through distance sensor 1 216 and distance sensor 2 218, the distance between the upper side of the protruding part on the lower side of connecting rod 3 212 can be detected, and this distance is the same as the distance between the upper and lower balls 214.
[0025] In use, the roller is placed between the two mounting pieces 27 and on the upper side of the bracket 22. The controller (existing technology, not shown in the figure) of the device body 11 controls the two telescopic ends of the dual-axis electric actuator 26 to shorten, so that the connecting pieces 28 on both sides are located at the two ends of the roller. By controlling the shortening of the telescopic end of the detection electric actuator 217, the connecting rod 212 and connecting rod 213 move upward, causing the ball bearing 214 on the upper side of connecting rod 213 to contact the lower side of the roller end. When the pressure detected by the pressure sensor 215 inside the lower side of connecting rod 212 reaches the set value, the detection electric actuator 217 stops working. Similarly, the telescopic ends of the detection electric actuator 29 are controlled to shorten. The extension of the end causes connecting rod 210 and connecting rod 211 to move downward, so that the ball 214 on the lower side of connecting rod 211 contacts the upper side of the roller end. When the pressure detected by the pressure sensor 215 on the lower side of connecting rod 210 reaches the set value, the detection electric push rod 29 will be controlled to stop working, so that the upper and lower balls 214 of the two connecting parts 28 on both sides can contact the upper and lower sides of the roller end respectively. The diameter of the roller end can be detected by the distance sensor 216 on both sides respectively. By controlling the extension end of the push electric push rod 24 to shorten and drive the slide rod 23 to move, the roller can be pushed along the bracket 22 to the grinding area between the grinding wheel 13 and the guide wheel 12.
[0026] The initial control component 3 includes a control box 31 fixedly connected to one side of the device body 11. An electric push rod 33 is fixedly connected to the inside of the control box 31. The electric push rod 33 is electrically connected to a distance sensor 216 and a distance sensor 218. A movable rack 34 is fixedly connected to the telescopic end of the electric push rod 33 and is slidably disposed with the inner wall of the control box 31. A guide groove 1 that cooperates with the movable rack 34 is provided on the inner wall of the control box 31. The movable rack 34 is slidably disposed along the guide groove 1 and can play a supporting and guiding role. A slide block 35 that is slidably disposed with the inner wall of the control box 31 is provided on the upper side of the movable rack 34. A guide groove 2 that cooperates with the slide block 35 is provided on the inner wall of the control box 31. The slide block 35 is slidably disposed along the guide groove 2. A gear 36 is rotatably disposed inside the slide block 35. The lower side of the gear 36 is meshed with the movable rack 34.
[0027] A fixed rack 37 is meshed on the upper side of the gear 36. The fixed rack 37 is fixedly connected to the inside of the control box 31. A metal rod 38 is provided on the upper side of the fixed rack 37. A connecting rod 39 is fixedly connected to the side end of the slide block 35. A conductive block 32 is fixedly connected to the other end of the connecting rod 39. The conductive block 32 and the metal rod 38 are slidably arranged. The guide wheel 12 is driven to rotate by the motor of the device body 11 (existing public technology). The metal rod 38 is electrically connected to the motor that drives the guide wheel 12 to rotate. The metal rod 38 is located on the side of the conductive block 32 away from the electric push rod 351, where the resistor is connected to the circuit.
[0028] The diameters of both ends of the roller are detected by the distance sensors 216 on both sides. When the detected roller end diameter is large, the output current signal will be large. Therefore, the controller of the device body 11 can make the electric push rod 33 have relatively high power, so that the extension end of the electric push rod 33 can extend and drive the moving rack 34 to move a greater distance. It can also drive the gear 36 to rotate, and the gear 36 can rotate along the fixed rack 37 and move forward synchronously. This can drive the slide 35 to move synchronously, and the distance that the slide 35 moves can be half the distance that the moving rack 34 moves. The moving distance of the slide 35 can be controlled according to the average diameter of the two ends of the tapered roller. The movement of the slide 35 can drive the connecting rod 39 and the conductive block 32 to move synchronously. When the roller end diameter is large, the moving distance of the conductive block 32 can be increased. The larger resistance of the metal rod 38 results in a higher resistance, which in turn allows for a lower power of the motor driving the guide wheel 12 to rotate. This reduces the rotational speed of the guide wheel 12, preventing excessive centrifugal force that could cause the roller to detach from the support point of the bracket 22 and vibrate. For large-diameter rollers, if the guide wheel 12 rotates too fast, the amount of grinding heat generated will also increase, easily leading to grinding burns on the roller surface (surface annealing discoloration or cracking). In addition, reducing the rotational speed of the guide wheel 12 can also facilitate the penetration of coolant into the grinding zone, controlling the grinding temperature. Conversely, for small-diameter rollers, the rotational speed of the guide wheel 12 can be relatively high to prevent the roller surface linear velocity from being too low, which would increase the relative slippage between the roller and the guide wheel 12 (i.e., "slippage"), affecting the rotational stability of the roller, causing grinding chatter, and thus affecting the roundness of the roller surface.
[0029] The correction component 4 includes a movable seat 41 slidably disposed on the inner wall of the control box 31. The inner wall of the control box 31 is provided with a guide groove three that cooperates with the movable seat 41. The movable seat 41 is slidably disposed along the guide groove three. The movable seat 41 is fixedly connected to the metal rod 38. An electric push rod two 42 is fixedly connected to the inner wall of the control box 31. The telescopic end of the electric push rod two 42 is fixedly connected to the movable seat 41. A distance sensor three 43 is provided on one side of the mounting component 27. The distance sensor three 43 is electrically connected to the electric push rod two 42. The distance sensor three 43 can detect the distance between the two mounting components 27. That is, when the two telescopic ends of the dual-axis electric push rod 26 are shortened, so that the connecting parts 28 on both sides are located at the two ends of the roller respectively, the length of the roller can be detected by the distance sensor three 43.
[0030] According to the detection of distance sensor 43, when the roller is long, its output current signal will be larger, resulting in greater power of electric push rod 42. This allows the extension end of electric push rod 42 to move the moving seat 41 and metal rod 38 a greater distance, further increasing the resistance of metal rod 38. This can further reduce the speed of guide wheel 12. However, for longer rollers, the frictional heat is greater, which can easily lead to an increase in the surface temperature of the roller, posing a risk of burns. In addition, for longer rollers, the contact area with guide wheel 12 is larger, resulting in a larger frictional resistance torque. If the speed is too high, the roller is prone to intermittent slippage, which will affect the grinding quality of the roller. By using correction component 4, the speed of guide wheel 12 can be lower as the roller length increases, so as to correct the speed of guide wheel 12 according to the roller length and further improve the grinding quality of the roller.
[0031] During the roller grinding process, the change in diameter caused by the grinding will alter the pressure detected by the pressure sensor 215 on the lower side of the connecting rod 210. This will control the detection electric push rod 29 to operate, driving the ball 214 on the lower side of the connecting rod 211 to contact the upper surface of the roller. When the pressure detected by the pressure sensor 215 reaches the set value, the detection electric push rod 29 will stop operating. The change in roller diameter can then be detected by the distance sensor 218, which will control the extension end of the electric push rod 33 to shorten, causing the moving rack 34 and slide 35 to move in the opposite direction. This will reduce the resistance of the metal rod 38, thereby increasing the rotational speed of the guide wheel 12 to adapt to the decrease in roller diameter. Within the set detection cycle, when the diameter change detected by the distance sensor 218 is large, its output signal is large, which will cause the electric push rod 33 to shorten its length significantly, adjusting the resistance change of the metal rod 38. This allows the rotational speed of the guide wheel 12 to be adjusted according to the amount of grinding, thereby improving the quality of roller grinding.
[0032] Example 2 The adjustment assembly 5 includes an electric push rod 51 fixedly connected to the slide block 35. The electric push rod 51 is electrically connected to the distance sensor 43. The telescopic end of the electric push rod 51 is fixedly connected to a sliding member 52. A connecting plate 53 fixedly connected to the control box 31 is slidably arranged on the upper side of the sliding member 52. A guide groove 4 that cooperates with the sliding member 52 is arranged on the lower side of the connecting plate 53. The sliding member 52 is slidably arranged along the guide groove 4.
[0033] The lower side of the sliding member 52 is fixedly connected to protrusion 1 54 and protrusion 2 55 respectively. The height of protrusion 2 55 is greater than the height of protrusion 1 54. The lower side of the connecting plate 53 is provided with two distance sensors 4 56. The upper distance sensor 4 56 corresponds to protrusion 1 54 and can detect the distance between protrusion 1 54, which corresponds to the lower limit of the set range of the speed ratio between the grinding wheel 13 and the guide wheel 12. The lower distance sensor 4 56 corresponds to protrusion 2 55 and can detect the distance between protrusion 2 55, which corresponds to the upper limit of the set range of the speed ratio between the grinding wheel 13 and the guide wheel 12.
[0034] When the electric push rod 33 is controlled to extend and retract to drive the slide block 35 to move, based on the detection of distance sensors 216 and 218, the electric push rod 51 and the sliding member 52 can move synchronously. Similarly, when the electric push rod 42 is controlled to extend and retract to drive the moving seat 41, based on the detection of distance sensor 43, the electric push rod 51 can simultaneously drive the sliding member 52 to move synchronously. This allows the sliding member 52 and the positions of protrusions 54 and 55 to be adjusted synchronously according to the roller diameter and length. By detecting the distance between the upper distance sensor 56 and protrusion 54, and the lower distance sensor 56 and protrusion 55, the area between protrusions 54 and 55 can be detected, corresponding to the set range of the rotational speed ratio between the grinding wheel 13 and the guide wheel 12. When the roller diameter is large or the length is long, this set range can be made relatively large to accommodate the grinding wheel's rotational speed. The high speed ratio between grinding wheel 13 and guide wheel 12 is achieved by installing a rotary encoder (existing technology) on the drive shaft of guide wheel 12 and grinding wheel 13. This encoder detects the speed ratio of grinding wheel 13 and guide wheel 12. The controller compares the detected speed ratio between grinding wheel 13 and guide wheel 12 with the speed ratio setting range adjusted according to the roller diameter and length. If the speed ratio is lower than the setting range, a speed adjustment signal is output to the motor of guide wheel 12 to control the motor driving the rotation of guide wheel 12 to decelerate, thereby reducing the speed of guide wheel 12 and raising the speed ratio between grinding wheel 13 and guide wheel 12 back to the setting range. This prevents the speed ratio from being too small, which can easily lead to vibration marks and burns on the roller surface, affecting fatigue life. Conversely, if the detected speed ratio between grinding wheel 13 and guide wheel 12 is higher than the setting range, the speed of guide wheel 12 is increased to reduce the speed ratio to the setting range. This prevents the speed ratio from being too large, which can lead to a decrease in grinding efficiency and possible surface deterioration due to frictional heat accumulation, thus ensuring the quality of roller grinding.
