Bearing outer ring automatic punching machine

Abstract

The invention relates to a bearing outer ring automatic punching machine. The bearing outer ring automatic punching machine comprises a bearing outer ring supply mechanism. A receiving plate is arranged below an outlet of the bearing outer ring supply mechanism, a bearing outer ring receiving mechanism is arranged at the middle position of the receiving plate, clamping jaws for clamping bearing outer rings are arranged at the position above the portion near the periphery of the receiving plate, the clamping jaws are equiangularly distributed in the circumferential direction and are synchronously close to or away from one another, punching drill bits are further arranged near the clamping jaws, a horizontally-pushing mechanism drives the receiving plate and is close to / away from a cleaningmechanism, bearing outer ring blanks are guided out through the supply mechanism to the receiving plate, the clamping jaws are started to be synchronously close to the center of the receiving plate,the outer walls of the bearing outer ring blanks are clamped, then the punching drill bits are started, the bearing outer ring blanks can be punched, the punched bearing outer ring blanks are pushed out through the horizontally-pushing mechanism, and the upper face of the receiving plate is cleaned through the cleaning mechanism, so that the cleanliness of the surface of a clamping mechanism is guaranteed, and the machining quality of the bearing outer rings is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bearing production, in particular to an automatic punching machine 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 generally oil injection holes on the outer ring of the bearing, and three oil injection holes are distributed equi...

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
