Description

Technical Field

[0001] The utility model relates to the technical field of bearing cutting, in particular to a high-efficiency cutting device for a bearing outer ring. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy.

[0003] At present, some existing cutting devices use clamps or claws to clamp the inner surface of the bearing to fix the bearing, but this clamping method has high requirements on the clamping force. When the clamping force is small, the fixing effect is not good, and the bearing may move during the cutting process. When the clamping force is large, the inner wall of the bearing may be subjected to excessive force and damaged and deformed, which is relatively inconvenient to use. Therefore, we propose a high-efficiency cutting device for the outer ring of the bearing to solve or improve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a high-efficiency bearing outer ring cutting device, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: it includes a workbench, a first drive motor fixed to the bottom of the workbench, a rotating table fixed to the top of the output shaft of the first drive motor, a slide groove opened at the top of the rotating table, a second drive motor fixed inside the rotating table, a threaded rod fixed to the top of the output shaft of the second drive motor, and a clamping component A arranged inside the slide groove.

[0006] Furthermore, the clamping assembly A includes a slider slidably installed inside the slide groove, a threaded rod passing through the interior of the slider and threadedly connected to the slider, an upper clamping block fixed to the top of the slider, a second spring fixed inside the slider, a clamping plate fixed to the top of the second spring, a lower clamping block arranged on one side of the bottom of the clamping plate, and a connecting block fixed to the surface of the lower clamping block.

[0007] Furthermore, the clamping assembly A also includes an upper fixed plate fixed to the top side of the slider surface, a lower fixed plate fixed to the bottom side of the slider surface, and a first spring fixed to the top of the lower fixed plate, one end of the first spring is fixed to the top of the lower fixed plate, and the other end is fixed to the bottom of the connecting block.

[0008] Furthermore, a fixed block is fixed on the top of the workbench, a hydraulic push rod is fixed inside the fixed block, and a cutting tool head is fixed on the top of the output shaft of the hydraulic push rod.

[0009] Furthermore, support legs are fixed to the bottom of the workbench, and a plurality of groups of support legs are symmetrically fixed to the bottom of the workbench.

[0010] Furthermore, a limiting rod is fixed on the top of the lower fixed plate, the limiting rod passes through the interior of the connecting block and is slidably connected to the connecting block, a limiting column is fixed on the bottom of the splint, one end of the limiting column passes through the interior of the slider and is slidably connected to the slider, and one end of the limiting column is fixed to the limiting plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects: by setting the clamping assembly A, the clamping plate can be moved under the pressure of the inner wall of the bearing when clamping the bearing. At this time, the first spring will push the connecting block to move so that the connecting block drives the lower clamping block to move so that the lower clamping block drives the bearing to move, thereby clamping the bearing between the upper clamping block and the lower clamping block. At the same time, the second spring will push the clamping plate so that the clamping plate is tightly attached to the inner surface of the bearing, so that the inner surface of the bearing is clamped by a plurality of groups of clamping plates. The requirement for clamping force during clamping is relatively small, which reduces or avoids the problem of poor fixing effect due to small clamping force or damage and deformation of the inner wall of the bearing due to excessive force due to large clamping force, and is relatively convenient to use.

The plurality of supporting feet 2 are used to support the main body of the device and ensure the stability of the device during operation. A first driving motor 3 is fixed at the bottom of the workbench 1, a rotating table 6 is fixed at the top of the output shaft of the first driving motor 3, and the first driving motor 3 can drive the rotating table 6 fixed at the top of the output shaft to rotate. A slide 7 is opened at the top of the rotating table 6, and a plurality of slides 7 are arranged in a circle at the top of the rotating table 6. A second driving motor 8 is fixed inside the rotating table 6, a threaded rod 9 is fixed at the top of the output shaft of the second driving motor 8, and the second driving motor 8 can drive the threaded rod 9 fixed at the top of the output shaft to rotate. A clamping assembly A is arranged inside the slide 7, and the number of clamping assemblies A is the same as the number of slides 7. A fixing block 4 is fixed at the top of the workbench 1, and a hydraulic push rod 5 is fixed inside the fixing block 4. A cutting head is fixed at the top of the output shaft of the hydraulic push rod 5, and the hydraulic push rod 5 can drive the cutting head fixed at the top of the output shaft to move, and the cutting head is located on one side of the clamping assembly A.

[0021] The clamping assembly A includes a slider 14 slidably installed in the slide groove 7, a threaded rod 9 passes through the interior of the slider 14 and is threadedly connected to the slider 14. When the threaded rod 9 rotates, the threaded slider 14 is driven to move. An upper clamping block 10 is fixed to the top of the slider 14, a second spring 18 is fixed to the interior of the slider 14, and a clamping plate 11 is fixed to the top of the second spring 18. The clamping plate 11 is located on the bottom side of the upper clamping block 10. When the clamping plate 11 moves, the second spring 18 is squeezed to deform the second spring 18. When there is no external interference, the second spring 18 pushes the clamping plate 11 to move and return to its initial position. A limiting column is fixed at the bottom of the clamping plate 11, one end of the limiting column passes through the interior of the slider 14 and is slidably connected to the slider 14, and a limiting plate is fixed to one end of the limiting column. The limiting column can limit the position of the clamping plate 11 to prevent the clamping plate 11 from tilting during the movement. The limiting plate can limit the position of the limiting column to prevent the limiting column from detaching from the interior of the slider 14, and a lower clamping block is set on one side of the bottom of the clamping plate 11. 12, the top of the lower clamping block 12 contacts the bottom of the clamping plate 11, and the connecting block 15 is fixed on the surface of the lower clamping block 12. The clamping assembly A also includes an upper fixing plate 13 fixed to the surface of the slider 14 near the top side, and a lower fixing plate 16 fixed to the surface of the slider 14 near the bottom side. A limiting rod is fixed on the top of the lower fixing plate 16, and the limiting rod passes through the interior of the connecting block 15 and is slidably connected to the connecting block 15. The limiting rod can limit the position of the connecting block 15 to prevent the connecting block 15 from moving too far. The first spring 17 is fixed to the top of the lower fixed plate 16, one end of the first spring 17 is fixed to the top of the lower fixed plate 16, and the other end is fixed to the bottom of the connecting block 15. The upper fixed plate 13, the connecting block 15, the first spring 17 and the lower fixed plate 16 are symmetrically arranged in two groups on both sides of the lower clamping block 12. When the clamping plate 11 moves and breaks away from the contact with the top of the lower clamping block 12, the first spring 17 will drive the fixed connecting block 15 to move, so that the connecting block 15 drives the fixed lower clamping block 12 to move.

[0022] Working principle: when it is necessary to cut the outer ring of the bearing, the bearing is sleeved on the surface of several groups of clamping components A, so that the bottom of the bearing is placed on the top of the lower clamping block 12. At this time, the second drive motor 8 will drive the threaded rod 9 to rotate, so that the threaded rod 9 drives the slider 14 to move. When the slider 14 moves, it will drive the fixed second spring 18 and the clamping plate 11 to move, so that the clamping plate 11 is tightly attached to the inner surface of the bearing and the inner surface of the bearing squeezes the clamping plate 11, so that the clamping plate 11 moves and breaks away from the contact with the top of the lower clamping block 12. At this time, the first spring 17 will push the connecting block 15 to move, so that the connecting block 15 drives the lower clamping block 12 to move. When the lower clamping block 12 moves, it will drive the bearing placed on the top to move, so that the bearing is clamped between the upper clamping block 10 and the lower clamping block 12. At the same time, the second spring 18 will push the clamping plate 11 so that the clamping plate 11 is tightly attached to the inner surface of the bearing. The inner surface of the bearing is clamped by a plurality of groups of clamping plates 11, and the clamping force required during clamping is relatively small, which reduces or avoids the problem of poor fixing effect due to small clamping force or damage and deformation of the inner wall of the bearing due to excessive force caused by large clamping force. It is relatively convenient to use, and the top and bottom of the bearing can be clamped by the upper clamping block 10 and the lower clamping block 12, which improves the clamping effect of the bearing and further reduces or avoids the movement of the bearing during the cutting process. After the clamping is completed, the rotating table 6 is driven to rotate by the first driving motor 3, so that the rotating table 6 can drive the slide 7 and the clamping assembly A slidably installed inside the slide 7 to rotate, so that the clamping assembly A drives the clamped bearing to rotate. At this time, the hydraulic push rod 5 pushes the cutting head to approach the outer ring of the bearing to cut the outer ring of the bearing, which is relatively convenient to use.
