Technical Field
[0001] The utility model relates to the field of bearing processing, in particular to a grinding device for processing a bearing inner ring. Background Art
[0002] The grinding device for inner ring processing of bearings is a device used to process inner rings of bearings. The inner ring of bearings is one of the core components of bearings and has very high processing accuracy and surface quality requirements. The inner ring of bearings is usually made of steel and can only achieve the required size and surface roughness after multiple complex processing processes. Grinding is a commonly used precision processing method in the processing of inner rings of bearings, which can achieve high-precision and high-surface quality processing effects.
[0003] The emergence of grinding devices for bearing inner ring processing is mainly to meet the requirements of high precision, high efficiency and stability in bearing inner ring processing. Traditional bearing inner ring processing methods may require multiple roughing, finishing, grinding and polishing, which are complex and inefficient. The use of specially designed grinding devices can integrate these processing steps and complete them in one go, which can improve processing efficiency, reduce production costs, and ensure product quality.
[0004] At present, the grinding device for processing the inner ring of the bearing uses a high-speed rotating grinding head to process the inner ring of the bearing fixed on the grinding table. At the same time, the moving trajectory of the grinding head or the rotating grinding table is controlled to grind various positions of the inner ring of the bearing. However, before grinding, the bearing needs to be fixed first. However, when fixing, the clamps need to be adjusted one by one to clamp the bearings, which is troublesome. Electric control is more expensive. Secondly, the grinding wheel is mostly installed on the mounting seat with screws and nuts, which is difficult to replace when worn. Therefore, a grinding device for processing the inner ring of the bearing is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a grinding device for processing the inner ring of a bearing, comprising a base 1, the outer wall of the base 1 is rotatably connected to a rotating shaft 2, the outer wall of the rotating shaft 2 is fixedly connected to a clamping seat 11, the electric drive rotating shaft 2 can drive the clamping seat 11 to rotate, thereby driving the bearing fixed above it to rotate, the outer wall of the rotating shaft 2 is rotatably connected to a disc 3, the outer wall of the clamping seat 11 is slidably connected to a clamping block 8, the outer wall above the clamping seat 11 is fixedly connected to a rectangular bar, the clamping block 8 slides along the outer wall of the rectangular bar to clamp or release the bearing, a slider 9 is fixedly connected to the bottom end of the clamping block 8, a slide groove 10 is provided on the inner wall of the disc 3, the outer wall of the slider 9 is slidably connected to the inner wall of the slide groove 10, when the disc 3 rotates, the position of the slide groove 10 can be changed by dragging the slider 9 to drive the clamping block 8 to slide along the rectangular bar, and a handle is fixedly connected to the side wall of the disc 3 4, the outer wall of the handle 4 is slidably connected to the inner wall of the clamping seat 11, and the handle 4 can be dragged along the side wall of the clamping seat 11 to drive the disc 3 to rotate. The inner wall of the handle 4 is elastically connected with a buckle assembly through a return spring a5, and the buckle assembly includes a clamping block 6, one end of the return spring a5 is fixedly connected to the inner wall of the clamping block 6, and the other end of the return spring a5 is fixedly connected to the inner wall of the handle 4. Pressing the clamping block 6 inward can squeeze the return spring a5 to retract. At the same time, the elastic force generated by the deformation of the return spring a5 gives the clamping block 6 a thrust in the opposite direction, prompting it to reset. A plurality of groups of clamping grooves 7 are provided on the side wall of the clamping seat 11, and the outer wall of the clamping block 6 is clamped with the inner wall of the clamping groove 7. When the clamping block 6 is completely retracted, it can be released from the clamping groove 7. At this time, the handle 4 can be dragged to drive the disc 3 to rotate, thereby controlling each group of clamping blocks 8 to fix the bearing.
[0032] Reference Figure 1 and Figure 4The outer wall of the base 1 is fixedly connected with a column 12, and the outer wall of the column 12 is slidably connected with a telescopic frame 13. The telescopic frame 13 can be electrically controlled to slide along the outer wall of the column 12 and to extend and retract. A motor 14 is welded on the top of the telescopic frame 13. A mounting seat 15 is fixedly connected to the output shaft of the motor 14. Starting the motor 14 can drive the mounting seat 15 to rotate. The inner wall of the mounting seat 15 is detachably connected with a grinding wheel 16. The mounting seat 15 drives the grinding wheel 16 to rotate at a high speed to grind the bearing. The inner wall of the mounting seat 15 is elastically connected to the limit block 19 through a reset spring b18. One end of the reset spring b18 is fixedly connected to the inner wall of the mounting seat 15, and the other end of the reset spring b18 is fixedly connected to the back of the limit block 19. The inner side of the limit block 19 is set as an inclined surface. During the process of inserting the grinding wheel 16 into the inner wall of the mounting seat 15, the outer wall of the grinding wheel 16 shaft squeezes the inclined surface of the limit block 19 to squeeze the reset spring b18 and retract it. At the same time, the elastic force generated by the deformation of the reset spring b18 gives the limit block 19 an elastic force in the opposite direction, prompting it to reset. A limit groove 17 is provided on the top of the grinding wheel 16. When the limit groove 17 is aligned with the limit block 19, the reset spring b18 pushes the limit block 19 out and snaps it into the limit groove 17, fixing the grinding wheel 16 on the mounting seat 15. The outer wall of the limit block 19 is snapped with the inner wall of the limit groove 17. The inner wall of the mounting seat 15 is slidably connected with a pull rod 20. The inner end of the pull rod 20 is fixedly connected to the back of the limit block 19. Pulling the pull rod 20 outward can drive the limit block 19 to be pulled out of the limit groove 17.
[0033] Working principle: Place the bearing to be processed on the disc 3 above the clamping seat 11, press the clamping block 6 inward to squeeze the reset spring a5 to retract, thereby releasing the clamping connection with the clamping slot 7, and then push the handle 4 along the side wall groove of the clamping seat 11 to drive the disc 3 to rotate. At this time, the slider 9 drives the clamping block 8 to slide inward along the rectangular strip on the outer wall of the clamping seat 11 under the action of the corresponding slide groove 10, thereby fixing the bearing placed on the disc 3. After fixing, the electric control telescopic frame 13 slides along the outer wall of the column 12, driving the grinding wheel 16 to descend and enter the inner side of the bearing, and then the electric control telescopic frame 13 is electrically controlled to slide ... After the retracting frame 13 drives the grinding wheel 16 to move and stick to the outer wall of the inner ring of the bearing, the motor 14 is started to make the mounting seat 15 drive the grinding wheel 16 to rotate highly to grind the bearing. At the same time, the rotating shaft 2 drives the clamping seat 11 to rotate, driving the bearing to rotate, so that various positions of the bearing can be ground. When the grinding wheel 16 is severely worn due to long-term use and needs to be replaced, the pull rod 20 is pulled outward to move the limit block 19 outward to release the engagement with the limit groove 17. At this time, the worn grinding wheel 16 can be removed and the new grinding wheel 16 can be inserted from the bottom of the mounting seat 15. The disassembly and assembly are relatively simple and no additional auxiliary tools are required.
