Automatic punching method for bearing outer ring

Abstract

The invention relates to an automatic punching method for a bearing outer ring. A cut bearing outer ring blank is guided into a bearing outer ring feeding mechanism; a material receiving plate is arranged below a discharging opening of the bearing outer ring feeding mechanism, and a bearing outer ring material receiving mechanism is started to enable a material receiving head to rise, so that thematerial receiving head rises to be close to the lower portion of the discharging opening of the bearing outer ring feeding mechanism, and the bearing outer ring is guided into the material receivinghead; a clamping jaw is started to realize clamping operation on the bearing outer ring; and a punching drill bit is started to be close to the bearing outer ring, so that the punching operation on the bearing outer ring is achieved; the punching drill bit retreats and resets, and then the upper end of the material receiving head is far away from the material receiving plate; a flat pushing mechanism is started, so that the material receiving plate moves horizontally, the material receiving plate is pushed out horizontally, a brush plate of a cleaning mechanism gets close to the material receiving plate, and the bearing outer ring on the upper surface of the material receiving plate is pushed out; and the material receiving head rises and drives the material receiving plate to rise, so that a cleaning brush ring abuts against the inner side surface of the clamping jaw. According to the automatic punching method, the cleaning of the surface of the clamping mechanism can be effectively guaranteed so as to improve the machining precision of bearings.

Description

technical field [0001] The invention relates to the technical field of bearing production, in particular to an automatic drilling method for the outer ring of a bearing. Background technique [0002] As a high-precision standard part, bearings require extremely high precision dimensions during production. In the actual production of bearings, the first choice is to produce the inner and outer rings of the bearing. The inner and outer rings of the bearing are mostly tubular parts, which have high requirements for precision and size. In order to improve the life of the bearing, butter is applied between the inner and outer rings of the bearing to prevent To reduce the friction generated when the bearing is working and improve the service life of the bearing, in order to facilitate the injection of grease between the inner and outer rings of the bearing, there are usually oil injection holes on the outer ring of the bearing, and three oil injection holes are equiangularly distr...

In the actual production of bearings, the first choice is to produce the inner and outer rings of the bearing. The inner and outer rings of the bearing are mostly tubular parts, which have high requirements for precision and size. In order to improve the life of the bearing, butter is applied between the inner and outer rings of the bearing to prevent To reduce the friction generated when the bearing is working and improve the service life of the bearing, in order to facilitate the injection of grease between the inner and outer rings of the bearing, there are generally oil injection holes on the outer ring of the bearing, and three oil injection holes are distributed equiangularly along the outer ring of the bearing. In the prior art, after clamping the outer ring of the bearing by means of a triangular chuck, a drill bit is set on the side of the triangular chuck to carry out the drilling operation on the outer ring of the bearing. The metal debris produced during drilling is easy to adhere to the chuck of the triangular chuck and the complete support plate of the bearing. During the clamping process of the new bearing outer ring, it is easy to cause scratches on the outer ring of the bearing. In addition, it is easy to reduce the clamping accuracy of the outer ring of the bearing, which in turn affects the machining accuracy of the outer ring of the bearing
