[0001] The utility model relates to the technical field of bearing bushing pressing, and particularly relates to a bearing bushing press. Background Technique

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0003] Through patent retrieval, it is found that a bearing bushing pressing device with the publication number of CN220943993U realizes the fixation of the bushing in a manner of tightening from the inside to the outside through the action of a fixed seat, a tightening sleeve, a tightening plate, an electric push rod II, and a connecting rod. Such fixation enables the bushing to have sufficient support strength during use, effectively avoiding the phenomenon of bending damage at the port of the bushing during the pressing process, and greatly improving the pressing quality of the device for the bearing bushing. However, its clamping block is relatively fixed. When it is necessary to clamp bearings of different sizes, it is relatively inconvenient to replace the clamping block, and its adaptability to bearings of different sizes is relatively poor, and it is relatively inconvenient to use. Therefore, we propose a bearing bushing press to solve or improve the above problems. Content of the Utility Model

[0010] Furthermore, two groups of chutes are symmetrically provided at the top of the workbench, and the number of the sliders, driving blocks, clamping blocks, connecting rods and limiting components is the same as that of the chutes.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-6, including a workbench 1, a support plate 2 fixed to the top of the workbench 1, an electric push rod 6 fixed to the bottom of the support plate 2, a fixed seat 7 fixed to the bottom of the output shaft of the electric push rod 6, a tightening sleeve 8 fixed to the bottom of the fixed seat 7. The structures, usage methods and functions of the electric push rod 6, the fixed seat 7 and the tightening sleeve 8 are the same as those of the above-mentioned comparative document and are prior art, so no detailed description will be given here. A chute 10 is opened on the top of the workbench 1, and two groups of chutes 10 are symmetrically opened on the top of the workbench 1. A bidirectional screw rod 9 is rotatably installed at the bottom of the workbench 1 through a bearing. One end of the bidirectional screw rod 9 passes through the surface of the workbench 1 and is rotatably connected to the workbench 1. One end of the bidirectional screw rod 9 passing through the surface of the workbench 1 is fixed with an adjusting handwheel 3. By rotating the adjusting handwheel 3, the fixed bidirectional screw rod 9 can be driven to rotate. A slider 4 is slidably installed inside the chute 10, and a driving block 12 is fixed to the bottom of the slider 4. The bidirectional screw rod 9 passes through the inside of the driving block 12 and is threadedly connected to the driving block 12. When the bidirectional screw rod 9 rotates, it will drive the threadedly connected driving block 12 to move. Two groups of driving blocks 12 are symmetrically arranged on the surface of the bidirectional screw rod 9. The two groups of driving blocks 12 can be driven to move towards each other by the bidirectional screw rod 9. A clamping block 5 is sleeved on the surface of the slider 4 near the top side. A jack is opened on the inner surface of the clamping block 5. When the driving block 12 moves, it will drive the fixed slider 4 to move. When the slider 4 moves, it will drive the clamping block 5 sleeved on the surface to move. A limiting component is arranged inside the slider 4.

[0021] The limiting component internally includes a moving block 13 inserted into the slider 4, a limiting block 15 inserted into the slider 4 and located on one side of the moving block 13. The limiting block 15 is inserted into the jack formed in the clamping block 5. The limiting block 15 can limit the position of the clamping block 5 to prevent the clamping block 5 from detaching from the top of the slider 4. The surface of the moving block 13 is provided with jacks. When the moving block 13 moves and the jack moves to one side of the limiting block 15, the limiting block 15 can be inserted into the interior of the jack. Two groups of jacks are symmetrically arranged on the surface of the moving block 13, and two groups of limiting blocks 15 are symmetrically inserted into the slider 4. A second spring 16 fixed to the bottom of the moving block 13, one end of the second spring 16 is fixed to the bottom of the moving block 13, and the other end is fixed to the inner surface of the slider 4. When the moving block 13 moves, it will squeeze the second spring 16 to cause the second spring 16 to deform. When there is no external force interference, the second spring 16 will push the moving block 13 to move. A connecting rod 11 fixed to the top of the moving block 13, the connecting rod 11 passes through the top of the slider 4 and is slidably connected to the slider 4. A pressing plate is fixed to the top of the connecting rod 11. When the connecting rod 11 moves, it will drive the fixed moving block 13 to move. A first spring 14 fixed to the interior of the slider 4, one end of the first spring 14 is fixed to the inner surface of the slider 4, and the other end is fixed to the surface of the limiting block 15 through a connecting plate. When the limiting block 15 moves, it will squeeze the first spring 14 to cause the first spring 14 to deform. When there is no external force interference, the first spring 14 will push the limiting block 15 to move through the connecting plate. The number of the slider 4, the driving block 12, the clamping block 5, the connecting rod 11 and the limiting component is the same as the number of the chute 10.

[0022] Working principle: When it is necessary to press-fit the bearing bushing, the bushing is sleeved on the surface of the tightening sleeve 8 and fixed by the tightening sleeve 8. At this time, the bearing is placed between the two clamping blocks 5 and the adjusting handwheel 3 is rotated. The adjusting handwheel 3 can drive the bidirectional screw 9 to rotate. When the bidirectional screw 9 rotates, it will drive the two driving blocks 12 to move in opposite directions, so that the two driving blocks 12 drive the slider 4 to move. When the slider 4 moves, it drives the clamping block 5 to move, so as to clamp and fix the bearing through the two clamping blocks 5. At this time, the electric push rod 6 drives the fixed seat 7 and the tightening sleeve 8 to move, so that the tightening sleeve 8 drives the bushing fixed on the surface to move, so as to press-fit the bushing on the surface of the tightening sleeve 8 between the bearings through the electric push rod 6. When it is necessary to clamp bearings of different sizes, by pressing the connecting rod 11, the connecting rod 11 can drive the moving block 13 to move. When the moving block 13 moves to a certain position, the jack on the surface will move to one side of the limiting block 15. At this time, the first spring 14 will push the limiting block 15 to move through the mounting plate, so that one end of the limiting block 15 is inserted into the jack opened on the surface of the moving block 13. At this time, the limiting block 15 will disengage from the jack on the inner surface of the clamping block 5, so that the limiting block 15 no longer limits the position of the clamping block 5. At this time, the clamping block 5 can be directly removed from one side of the top of the slider 4 and the clamping block 5 can be removed from the surface of the slider 4. At this time, a new clamping block 5 is sleeved on the surface of the slider 4 and the connecting rod 11 is loosened. The second spring 16 can push the moving block 13 to move. When the moving block 13 moves, it will squeeze the surface of the limiting block 15 and make the limiting block 15 move towards the side close to the clamping block 5. At this time, the limiting block 15 will move towards the side close to the clamping block 5 under the extrusion of the moving block 13 and one end will be inserted into the jack opened inside the clamping block 5, so as to limit the position of the clamping block 5 through the limiting block 15, completing the replacement of the clamping block 5. The replacement of the clamping block 5 is relatively convenient, the adaptability to bearings of different sizes is relatively good, and the use is relatively convenient.
