Description

Technical Field

[0001] The utility model belongs to the technical field of bearing production equipment, and in particular relates to a device for machining grooves on the outer circumferential surface of a bearing. Background Art

[0002] Bearings are composed of an inner ring, an outer ring, rolling elements, a cage, and grease. Grooves are provided on the outer circumference of the bearing and the inner diameter of the outer ring to guide the rolling elements to rotate on the correct track.

[0003] When machining grooves on the outer circumference of the inner ring of a bearing, the traditional fixing method is to clamp the inner ring of the bearing on a three-jaw chuck. However, we found during machining that since the inner ring of the bearing is annular, excessive clamping of the three-jaw chuck will cause slight deformation of the inner ring of the bearing, thus affecting the quality of the product. In order to ensure that the inner ring of the bearing does not deform when machining the groove, we propose a device for machining grooves on the outer circumference of the bearing.

The surfaces of the three claws on the three-jaw chuck 6 are provided with sliding grooves (the claws are the structure on the three-jaw chuck 6, which is the prior art and is therefore not described in detail). The inner wall of the sliding groove is slidably connected with a clamping plate 7, and the inner wall of the sliding groove is provided with a buffer assembly, which includes a guide rod 8 fixedly mounted on the inner wall of the sliding groove, and the surface of the clamping plate 7 is provided with a guide rod 8 for guiding The rod 8 passes through a through hole, and a compression spring 9 is sleeved on the surface of the guide rod 8, one end of the compression spring 9 is fixedly connected to one side of the clamping plate 7, and the other end of the compression spring 9 is fixedly connected to the inner wall of the sliding groove. When the bearing ring 2 is placed between the three clamping plates 7, driving the three-jaw chuck 6 can drive the three claws on the three-jaw chuck 6 to move synchronously, thereby driving the three clamping plates 7 to move synchronously and contact the bearing ring 2. At this time, the compression spring 9 is stressed and is in a contracted state.

The positioning plate 10 and the connecting plate 5 can be fixedly connected as a whole by external bolts, so that the positioning assembly can be replaced according to the bearing ring 2 with different inner diameter specifications.

[0033] After the bearing ring 2 is clamped and centered by the clamping plate 7, the electric telescopic rod 4 is then driven to drive the positioning plate 10 to move to the right and contact the left end of the bearing ring 2, so that the two ends of the bearing ring 2 can be clamped and fixed. At this time, the positioning protrusion 11 will be inserted into the inner diameter of the bearing ring 2 to further position the bearing ring 2.
