Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a bearing running table for bearing processing. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Based on the different frictional properties of the moving elements, bearings can be divided into two main categories: rolling bearings and sliding bearings. Rolling bearings have been standardized and serialized, but compared with sliding bearings, they have larger radial dimensions, greater vibration and noise, and are also more expensive.

[0003] A search revealed that prior art publication number CN220881620U discloses a bearing break-in table, including a base plate, a support platform located on one side of the top of the base plate, and a support plate located on the side of the top of the base plate away from the support platform. The base plate includes: a support block located on one side of the top of the base plate, and a movable groove provided at the middle position of the top of the support platform; and adjusting plates located on both sides inside the support platform, with clamping plates penetrating into the movable groove at the middle position of the top of each of the two sets of adjusting plates. Each of the clamping plates has a protrusion on one side. This utility model utilizes the positive and negative threads at both ends of a bidirectional threaded rod and the threaded holes inside the two sets of adjusting plates to cooperate with each other, allowing the two sets of adjusting plates to drive the clamping plates to adjust in opposite directions inside the movable groove, thereby ensuring tight contact between the clamping plates and the inner ring of the bearing. The protrusions support the bearing, resulting in better bearing fixation. It can fix bearings of different models, improving the practicality of the break-in table.

[0004] However, this utility model can only meet the requirements for the outer ring of the bearing, and the inner ring cannot be run in. This leads to a slight error in the inner ring during the assembly process, which makes it unable to connect stably with the shaft. Therefore, a bearing running table for bearing processing is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bearing running-in table for bearing processing, which has the advantages of being able to run in both the outer and inner rings. This solves the problem that only the outer ring of the bearing can be run in, while the inner ring cannot be run in, resulting in minor errors in the inner ring during assembly that prevent it from being stably connected to the shaft.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bearing running table for bearing processing, comprising a running table body, a bearing limiting device provided on the right side of the running table body, and a bearing inner ring running structure provided on the inner wall of the upper side of the running table body.

[0007] The bearing limiting device includes a right-end motor fixedly installed on the lower side of the running table body, a rotating shaft fixedly connected to the output end of the motor, a first gear sleeved on the outer side of the rotating shaft, a second gear meshing with the left side of the first gear, a column fixedly connected to the lower side of the second gear, and a connecting cylinder sleeved on the inner wall of the second gear.

[0008] The bearing inner ring running-in structure includes a turntable sleeved on the inner wall of the platform, two second threaded rods inserted into the inside of the turntable, a running-in column fixedly connected to the upper side of the second threaded rods, an anti-slip limiting plate fixedly connected to one side of the running-in column, and multiple positioning holes opened inside the turntable that are compatible with the second threaded rods.

[0009] Furthermore, an outer ring running structure is provided on the upper side of the running table body. The outer ring running structure includes a left end support plate fixedly connected to the upper side of the running table body, a first threaded rod threadedly connected to the inside of the support plate, a right side running plate sleeved on the first threaded rod, and an upper end slide rod fixedly connected to the left side of the running plate.

[0010] Furthermore, the connecting cylinder has two sliding blocks inside, and the connecting cylinder has a groove inside that matches the blocks.

[0011] Furthermore, a nut is threaded onto the outer wall of the second threaded rod, and a limit plate is fixedly connected to one end of the turntable on the lower side.

[0012] Furthermore, a pin is inserted into the interior of the limiting plate, and the top of the pin penetrates the limiting plate and extends into the interior of its running table body.

[0013] Furthermore, the plurality of positioning holes are arranged at equal intervals, and an anti-slip pad is embedded on the side of the anti-slip limiting plate away from the running-in column.

[0014] Furthermore, the anti-slip mat is a rubber anti-slip mat.

[0015] Compared with the prior art, this utility model provides a bearing running table for bearing processing, which has the following beneficial effects:

[0016] 1. This bearing running table for bearing processing uses a running plate to run the outer ring of the bearing. After the running column rotates in the positioning hole and comes into contact with the inner ring of the bearing, it is then fixed by the nut thread, thus realizing the running-in treatment of the inner ring of the bearing.

[0017] 2. This bearing running table for bearing processing uses a running column inserted into different positioning holes on the lower side, with anti-slip limiting plates contacting the inner ring surface of the bearing. This allows different types of bearings to be clamped and fixed on the upper side of the connecting cylinder. This solves the problem that only the outer ring of the bearing can be run-in, while the inner ring cannot be run-in, which leads to minor errors in the inner ring during assembly and makes it impossible to connect stably with the shaft.

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.

[0023] Please see Figures 1 to 3 This embodiment of a bearing running table for bearing processing includes a running table body 1. A bearing limiting device is provided on the right side of the running table body 1, and a bearing inner ring running structure is provided on the inner wall of the upper side of the running table body 1. The bearing limiting device includes a right-end motor 6 fixedly installed on the lower side of the running table body 1, a rotating shaft 7 fixedly connected to the output end of the motor 6, a first gear 8 sleeved on the outer side of the rotating shaft 7, a second gear 9 meshing with the left side of the first gear 8, a column 10 fixedly connected to the lower side of the second gear 9, and a connecting cylinder 11 sleeved on the inner wall of the second gear 9. The bearing inner ring running structure includes a turntable 19 sleeved on the inner wall of the column 10, two second threaded rods 15 inserted into the inside of the turntable 19, a running column 13 fixedly connected to the upper side of the second threaded rods 15, an anti-slip limiting plate 14 fixedly connected to one side of the running column 13, and a plurality of positioning holes 20 opened inside the turntable 19 and adapted to the second threaded rods 15.

[0024] The upper side of the running table body 1 is provided with an outer ring running structure, which includes a left end support plate 2 fixedly connected to the upper side of the running table body 1, a first threaded rod 3 threadedly connected to the inside of the support plate 2, a right side running plate 4 sleeved on the first threaded rod 3, and an upper end slide rod 5 fixedly connected to the left side of the running plate 4. Two locking blocks 12 are slidably connected inside the connecting cylinder 11. The inside of the connecting cylinder 11 is provided with a sliding groove 18 that matches the locking blocks 12. A nut 16 is threadedly connected to the outer wall of the second threaded rod 15. A limiting plate 17 is fixedly connected to one end of the lower side of the turntable 19. A pin is inserted into the inside of the limiting plate 17. The top of the pin passes through the limiting plate 17 and extends into the inside of the running table body 1. Multiple positioning holes 20 are arranged at equal intervals. An anti-slip pad is embedded on the side of the anti-slip limiting plate 14 away from the running column 13. The anti-slip pad is a rubber anti-slip pad.

[0025] The working principle of the above embodiments is as follows:

[0026] The bearing is placed on the upper side of the connecting cylinder 11. The second threaded rod 15 at the bottom of the running-in column 13 is inserted into the corresponding positioning hole 20 and fixed by the nut 16. At the same time, the anti-slip limiting plate 14 on one side of the running-in column 13 abuts against the inner ring surface of the bearing for support. The first threaded rod 3 rotates, driving the running-in plate 4 to move to the outer ring surface of the bearing. The motor 6 starts, driving the first gear 8 to mesh with the second gear 9, synchronously driving the bearing to rotate and perform running-in treatment on the outer ring. After the outer ring is run-in, a pin is inserted through the limiting plate 17 into the interior of the running table body 1 to realize rotation. With the disc 19 fixed in place and the running plate 4 away from the outer side of the bearing, the locking block 12 is removed and slidably engaged with the outer ring of the bearing in the slide groove 18. Then, the limiting position of the second threaded rod 15 is removed, and the running column 13 is rotated again to change the position of the anti-slip limiting plate 14 and the running column 13. The outer side of the running column 13 is used to abut against the inner ring of the bearing. The second threaded rod 15 is then aligned with the nut 16 and limited again. The first gear 8 is activated to mesh with the second gear 9, which drives the column 10 and the upper bearing to rotate. During the movement of the inner ring of the bearing, the running column 13 performs running-in treatment on the inner wall.
