Description
Technical Field
[0001] This utility model relates to the field of bearing processing technology, and in particular to a grinding device for the roller ball base surface of a tapered bearing. Background Technology
[0002] In the manufacturing process of tapered roller bearings, the grinding of the spherical base surface of the rollers is a crucial step, directly affecting the bearing's operational accuracy, service life, and overall performance. Traditional grinding methods often employ manual operation or simple mechanized equipment, resulting in low grinding efficiency, low machining accuracy, complex operation, and high time and labor costs.
[0003] Specifically, traditional grinding equipment for tapered roller bearings often lacks an effective clamping and fixing mechanism, causing the rollers to easily wobble or shift during grinding, thus affecting grinding accuracy and surface quality. Furthermore, because the rollers are easily subjected to the direct action of the grinding tool during grinding, they rotate along with it, which not only reduces grinding efficiency but may also cause scratches or damage to the roller surface. In addition, traditional grinding equipment often struggles to achieve relative rotation between the tapered rollers and the grinding tool during grinding, resulting in uneven grinding and difficulty in achieving ideal processing results. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a grinding device for the ball bearing roller base surface of tapered bearings, which has the advantages of convenient clamping, effective control of roller rotation, improved grinding efficiency and processing quality, and solves some of the problems mentioned in the background technology.
[0005] This utility model provides the following technical solution: a grinding device for the roller ball base surface of a tapered bearing, comprising a processing table, a lifting platform slidably installed inside the upper end of the processing table, a tapered bore bearing passing through and fixedly installed in the middle of the interior of the lifting platform, a rubber sleeve provided in the bore of the tapered bore bearing, a cup-shaped grinding head rotatably installed on the upper side of the tapered bore bearing on the processing table, a drive shaft rotatably installed in the middle of the upper end of the processing table, a collar fixedly connected to the lower end of the inner ring of the tapered bore bearing, the upper end of the drive shaft extending through the collar into the interior of the tapered bore bearing, limit blocks symmetrically provided on the left and right inner walls of the collar, and lifting grooves provided at both ends of the drive shaft, the limit blocks being slidably connected inside the lifting grooves.
[0006] Furthermore, a release bearing is provided in the middle of the interior of the cup-shaped grinding head, a stop rod is slidably installed inside the release bearing, and a slide rod is slidably connected in the middle of the interior of the stop rod. The upper end of the slide rod is fixedly connected to the cup-shaped grinding head, and a clamping spring is provided between the inner bottom of the stop rod and the slide rod. This structure can effectively prevent the cup-shaped grinding head from applying additional rotational force to the tapered roller through the stop rod when it rotates during grinding.
[0007] Furthermore, electric push rods are fixedly installed at the four corners of the upper end of the processing table. The upper output end of the electric push rod is fixedly connected to the lifting platform. The two ends of the lifting platform also form a sliding limit relationship with the vertical plate of the processing table to improve stability.
[0008] Furthermore, a rotating shaft is rotatably mounted on the processing table near the middle of the right side. Two sets of opposing main bevel gears are fixedly sleeved on the outer side of the rotating shaft near the upper and lower sides. The left ends of the two sets of main bevel gears are meshed with bevel gear transmission components, which can realize transmission while also changing the direction of rotation.
[0009] Furthermore, a first bevel gear is fixedly sleeved on the upper end of the bowl-shaped grinding head. The first bevel gear is meshed with the upper bevel gear transmission assembly, that is, the bowl-shaped grinding head can be rotated after the shaft rotates and the transmission is completed.
[0010] Furthermore, a second bevel gear is fixedly sleeved on the outer side of the drive shaft near its lower end. The second bevel gear meshes with the lower bevel gear transmission assembly, meaning that the drive shaft can be rotated after being driven by the rotation of the shaft.
[0011] The advantages of this utility model are as follows:
[0012] 1. The tapered bearing roller ball surface grinding equipment of this utility model achieves stable clamping and fixing of tapered rollers and efficient grinding. The drive motor drives the rotating shaft and the main bevel gear to rotate, and then through the transmission of the bevel gear transmission assembly, the bevel gear rotates in the opposite direction, thereby driving the cup-shaped grinding head and the transmission shaft to rotate in different directions. This design not only improves grinding efficiency, but also ensures the stability of the tapered rollers during the grinding process, avoiding machining accuracy problems caused by shaking or offset. At the same time, due to the design of the release bearing, the tapered rollers are effectively prevented from rotating with the cup-shaped grinding head, further ensuring the grinding effect and machining quality.
[0013] 2. The lifting platform is controlled by an electric push rod to achieve automatic clamping and ejection of tapered rollers. The clamping process utilizes the rebound force of the clamping spring to complete automatic clamping and fixing, which is simple and convenient to operate, reducing the labor intensity and operation difficulty of workers. Moreover, after ejecting the tapered rollers, the equipment can ensure that there is enough space to put in the next set of tapered rollers, ensuring the continuity of the processing flow and the rationality of equipment operation, and achieving efficient cyclic processing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-4A grinding device for the roller ball base surface of a tapered bearing includes a processing table 1. A lifting table 2 is slidably mounted inside the upper end of the processing table 1. A tapered bore bearing 3 is inserted through and fixedly mounted in the middle of the lifting table 2. A rubber sleeve 4 is provided inside the bore of the tapered bore bearing 3. A cup-shaped grinding head 5 is rotatably mounted on the upper side of the tapered bore bearing 3 on the processing table 1. A drive shaft 11 is rotatably mounted in the middle of the upper end of the processing table 1. A collar 12 is fixedly connected to the lower end of the inner ring of the tapered bore bearing 3. The upper end of the drive shaft 11 extends through the collar 12 into the interior of the tapered bore bearing 3. Limiting blocks 13 are symmetrically arranged on the left and right inner walls of the collar 12. Lifting grooves 14 are provided at both ends of the drive shaft 11. The limiting blocks 13 are slidably connected to the roller ball base surface of the tapered bore bearing 3. Inside the lifting groove 14, this device utilizes the tapered bore structure of the tapered bore bearing 3 to neatly house the rollers of the tapered bearing, leaving their upper ends exposed for subsequent grinding operations. A release bearing 6 is located in the center of the bowl-shaped grinding head 5. A stop rod 7 is slidably mounted inside the release bearing 6, and a slide rod 8 is slidably connected to the center of the stop rod 7. The upper end of the slide rod 8 is fixedly connected to the bowl-shaped grinding head 5. A retaining spring 9 is located between the inner bottom of the stop rod 7 and the slide rod 8. Electric push rods 10 are fixedly mounted at the four corners of the upper end of the processing table 1. The upper output end of the electric push rod 10 is fixedly connected to the lifting table 2. When the electric push rod 10 is opened, its output end drives the lifting table 2 to rise. The lifting platform 2 drives the tapered bore bearing 3 to bring its internal tapered rollers into contact with the abutment rod 7. Simultaneously, the spring 9 contracts and deforms, using the rebound force to gradually increase the force between the abutment rod 7 and the tapered rollers. Ultimately, when the upper end of the tapered rollers contacts the cup-shaped grinding head 5, clamping and fixing them simultaneously. Furthermore, due to the design of the release bearing 6, the tapered rollers are effectively prevented from rotating under the influence of the cup-shaped grinding head 5, ensuring the grinding effect of the cup-shaped grinding head 5 on the tapered rollers and guaranteeing the rationality of the structural design. In addition, since the rotation direction of the drive shaft 11 is opposite to that of the cup-shaped grinding head 5, the rotation of the drive shaft 11 drives the collar 12 to rotate synchronously. The rotation of the collar 12 drives the tapered bore bearing... The inner ring of bearing 3 rotates synchronously, and the design of the rubber sleeve 4 further improves the stability of the tapered roller. As a result, the tapered roller can rotate in the opposite direction to the cup-shaped grinding head 5 under the drive of the drive shaft 11. This can effectively improve the grinding efficiency of the curved surface at its upper edge, reduce production time, and improve processing quality. Finally, by controlling the electric push rod 10 to lower the lifting platform 2, the upper end of the drive shaft 11 can push the tapered roller directly out of the tapered bearing 3 through its contact with the interior of the tapered bearing 3, making it easy to pick up. At the same time, it also ensures that there is enough space between the upper end of the tapered bearing 3 and the cup-shaped grinding head 5 to place the next set of tapered rollers inside, thus ensuring the rationality and completeness of this technical solution.
[0021] Please see Figures 1-2On the processing table 1, a rotating shaft 15 is rotatably mounted near the middle of the right side. Two sets of opposing main bevel gears 16 are fixedly sleeved on the outer side of the rotating shaft 15 near the upper and lower sides. The left ends of both sets of main bevel gears 16 are meshed with bevel gear transmission assemblies 17. A driven bevel gear 18 is fixedly sleeved on the upper end of the cup-shaped grinding head 5. The driven bevel gear 18 meshes with the upper bevel gear transmission assembly 17. A driven bevel gear 2 19 is fixedly sleeved on the outer side of the transmission shaft 11 near the lower end. The driven bevel gear 2 19 is meshed with the lower bevel gear transmission assembly. The two gears 17 are meshed together. The lower end of the rotating shaft 15 passes through the interior of the processing table 1 and is fixedly connected to the output end of the drive motor. By turning on the switch button, the drive motor can drive the rotating shaft 15 to rotate. The rotation of the rotating shaft 15 can cause the two sets of opposing main bevel gears 16 to rotate. After being driven by the bevel gear transmission assembly 17, the driven bevel gear 18 and the driven bevel gear 19 can rotate in opposite directions. That is, when the bowl-shaped grinding head 5 rotates clockwise, the transmission shaft 11 will rotate counterclockwise.
[0022] Working Principle: This device utilizes the tapered bore structure of the tapered bore bearing 3 to neatly house the rollers of the tapered bearing, leaving their upper ends exposed for subsequent grinding operations. The lower end of the rotating shaft 15 penetrates the interior of the machining table 1 and is fixedly connected to the output end of the drive motor. By turning on the switch, the drive motor can rotate the rotating shaft 15. The rotation of the rotating shaft 15 causes the two sets of opposing main bevel gears 16 to rotate. After being transmitted through the bevel gear transmission assembly 17, the driven bevel gear 18 and driven bevel gear 19 can rotate in opposite directions. That is, when the cup-shaped grinding head 5 rotates clockwise, the transmission shaft 11 will rotate counterclockwise. Furthermore, when the electric push rod 10 is opened and its output end drives the lifting platform 2 to rise, the lifting platform 2 will drive the tapered bearing 3 to make the tapered roller inside contact with the push rod 7, and at the same time, the push spring 9 will contract and deform. Since the rotation direction of the drive shaft 11 is opposite to that of the cup-shaped grinding head 5, the rotation of the drive shaft 11 will drive the collar 12 to rotate synchronously. The rotation of the collar 12 can drive the inner ring of the tapered bearing 3 to rotate synchronously. At the same time, the design of the rubber sleeve 4 can further improve the stability of the tapered roller. Thus, the tapered roller can be driven by the drive shaft 11 to rotate in the opposite direction to the cup-shaped grinding head 5, thereby effectively improving the grinding efficiency of the curved surface at its upper edge.
