[0002] The grinding of automobile hub bearings is carried out on a bearing CNC grinder. When the hub bearings to be processed are sent to the workbench position in the grinder, a corresponding feeding mechanism is required. The current grinding operation is carried out by the third-generation hub bearing grinder, which is internally provided with a manipulator part and a workbench part. The manipulator clamps the hub bearings through a rotatable telescopic clamping claw, so that the material is clamped at the workbench position. The workbench position is fixed by a set structure, and then the outer side is ground; However, the loading and unloading effect of the above-mentioned grinding machine robot cannot effectively meet the existing production needs.

[0022] Working principle: Loading and unloading operation: the unpolished hub bearing is transported from the first guide frame 12 to one end of the guide plate 11, the first motor 31 drives the second electric push rod 32 to rotate, the second electric push rod 32 pushes and pulls the fixed frame 33 to move its position to correspond to the hub bearing material position, at this time the third electric push rod 34 pushes the linkage rod 38 to make the movable plate 35 slide inside the fixed frame 33, the first tooth plate 352 is meshed at one end of the first gear 372, the grinding rod 363 is inserted into the inner side of the hub bearing at this time, and the second motor 376 drives the transmission rod 371 to rotate The first gear 372 is rotated and meshed with the first tooth plate 352, and the first tooth plate 352 drives the first adjustment plate 36 to rotate so that the first slider 362 drives the grinding rod 363 to move. At this time, the grinding rod 363 is adapted to fit the inner side of the wheel hub bearing, and the synchronous extrusion block 365 is elastically extruded on the inner side of the wheel hub bearing under the support of the first support cylinder 366, completing the tightening and fixing operation of the wheel hub bearing. Then, the first motor 31 drives the second electric push rod 32 to rotate and swing, driving the wheel hub bearing to the position of the working chamber 41, triggering the subsequent fixing operation to complete the loading; Similarly, after the side of the wheel hub bearing is polished, the same operation is performed to tighten and fix the inner side of the wheel hub bearing, and then the first motor 31 drives the second electric push rod 32 to rotate, and the second electric push rod 32 pulls the fixing frame 33 to move, so that the wheel hub bearing swings to the position of the second guide frame 13. After the wheel hub bearing is loosened, the third electric push rod 34 pulls the movable plate 35 with the polishing rod 363 away from the inner side of the wheel hub bearing, and the wheel hub bearing is guided to the external material receiving position through the second guide frame 13; Outer side grinding: At this time, the wheel hub bearing is tightened to the position of the working chamber 41 by the grinding rod 363, and the fourth electric push rod 43 pulls the fixed plate 42 to make the second adjustment plate 451 frictionally sleeved on the side position of the linkage block 454, and the third motor 44 drives the second adjustment plate 451 to rotate and drive the second slider 461 to move and adjust to the inner side of the wheel hub bearing, and the fourth electric push rod 43 pushes the fixed plate 42 to make the second slider 461 squeeze and fit on the inner side of the wheel hub bearing to further fix it, and the fixed plate 42 fits on the side of the convex circular shaft of the third motor 44 and is fixed by friction, and then the third electric push rod 34 pushes the linkage rod 38 to drive the movable plate 35 to move closer to the fixed plate 42. At this time, the first tooth plate 352 is disengaged from the first gear 372, and the second tooth plate 353 is meshed with the side of the second gear 374. Then, the detection rod 381 is continuously pushed and squeezed on the side of the first tooth plate 352 to fix it. When the second motor 376 drives the transmission rod 371 to rotate, the second gear 374 is then meshed with the second tooth plate 353 to drive the movable plate 35 to rotate as a whole. At this time, the wheel hub bearing is tightened and rotates accordingly. The fixed plate 42 as a whole is driven by the third motor 44 to rotate synchronously under the constraint and guidance of the fourth electric push rod 43 to ensure the stable rotation of the wheel hub bearing. The first electric push rod 21 pushes the grinding block 2 to approach the outer side of the wheel hub bearing to perform the outer side grinding operation; Inner side grinding: After the outer side grinding, the first electric push rod 21 pulls the grinding block 2 to complete the reset, and the fourth electric push rod 43 pulls the fixing plate 42 away from the hub bearing. At this time, the second adjustment plate 451 is frictionally sleeved on the side of the linkage block 454, and the third motor 44 drives the second slider 461 to complete the position adjustment so that the second slider 461 corresponds to the outer side of the hub bearing. The fourth electric push rod 43 pushes the fixing plate 42 so that the second slider 461 is fixed to the outer side of the hub bearing. The fixing plate 42 is attached to the side of the convex circular shaft of the third motor 44 and is fixed by friction. Then, the third electric push rod 34 pulls the movable plate 35 to make the first tooth plate 352 mesh with the side of the first gear 372, and the second motor 376 drives the grinding rod 363 to relax slightly to avoid excessive friction in subsequent grinding. The third electric push rod 34 pushes the movable plate 35 to make the second tooth plate 353 mesh with the side of the second gear 374, and the second motor 376 drives the movable plate 35 to rotate as a whole, and the wheel hub bearing is clamped by the second slider 461 to ensure that it does not move, and the grinding rod 363 performs a grinding operation on the inner side of the wheel hub bearing; Sparks generated by the above grinding are cooled by spraying coolant through an external pipe, and the guide plate 11 guides the coolant to flow out from the inside of the guide groove 14 to avoid scattering of the coolant and affecting subsequent cleaning operations.

[0023] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
