Description

Fixing jig of bearing material and processing method of bearing material using the same {Fixing zig for bearing materal and metod thereof}

The present invention relates to a bearing material fixing jig and a method for processing a bearing material using the same, specifically, cutting and cutting a peak material made of a cylinder in a horizontal and vertical direction to form a bearing material for inner and outer rings forming a bearing, The present invention relates to a bearing material fixing jig and a method of processing a bearing material using the same, which enables stable cutting to prevent a shape change of the formed bearing material.

The bearing refers to a mechanical structure that fixes the axis of the rotating machine at a fixed position, supports the weight of the axis and the load applied to the axis, and achieves rotation of the axis.

Such a bearing is formed by cutting and cutting a rod of a peak material having high heat resistance, wear resistance, and chemical resistance to form an inner ring and an outer ring forming a bearing.

For example, conventionally, as in document (1), after forming the inner ring and outer ring forming the bearing cam by automatically supplying and cutting and cutting the peak material constituting the bearing cap material using the configuration of the cutting machine for the bearing cap material, As in documents (2) and (3), the inner and outer rings of the outer ring and the outer ring formed through the cutting machine for the bearing cap material were cut out to form inner and outer rings forming the bearing.

That is, in the conventional bearing forming process, to form the outer ring of the bearing, the outer diameter of the peak material, and the inner diameter of the peak material are cut to form the bearing material forming the inner ring and the outer ring, respectively. The outer diameter of the bearing is cut out to form the outer and inner rings of the bearing, and the bearing is formed by fixing a plurality of balls to be inserted therebetween in the process of combining the formed inner and outer rings.

However, in the conventional bearing forming process, the peak material forming the rod is cut and cut to form the inner and outer rings of the bearings separately, thereby cutting the peak material that is cut in the process of forming the inner ring of the bearing and the peak that is cut in the process of forming the outer ring of the bearing. There was a problem in that the production cost for forming the bearing was unnecessarily increased because unnecessary waste of the pico material forming a high price was wasted because the material was wasted.

In addition, in order to cut the inner diameter of the bearing material formed by cutting and cutting the peak material, even when forming a cutting process by combining with a jig fixing the bearing material, the outer shape of the bearing material inserted into the jig due to the pressure of the clamp transmitted to the jig Due to this deformation, precise machining was difficult, and thus there was a problem that the defect rate increased and productivity decreased.
