Abstract

The invention provides a traverse feeding device of an external groove plungecut grinder. The traverse feeding device comprises a roller cross guide rail pair, a traverse feed table and a drive unit, wherein the roller cross guide rail pair comprises guide rails, a roller retainer and a cylindrical roller, and the cylindrical roller is arranged on the guide rails through the roller retainer; the drive unit comprises a stepping motor, a harmonic speed reducer and a ballscrew, wherein the stepping motor drives the harmonic speed reducer to connect the ballscrew, an output shaft of the harmonic speed reducer is fixedly connected with a shaft end of a screw of the ballscrew, a nut of the ballscrew is connected with the transverse feed table, and the nut of the ballscrew can move forth and back on the screw of the ballscrew. By means of the transverse feeding device, the deceleration with large rotation ratio can be carried out through the harmonic speed reducer so that the transverse feeding is more stable, and the transverse feeding precision is improved by controlling the stepping motor through electric programs, thus accurate feeding and reversing are realized, and the machining precision of a bearing ring is accurate; and simultaneously, the stroke of the transverse feeding is also enlarged, the purchase cost of new equipment is reduced, and the purpose of a machine tool is widened.

Description

(1) Technical field

[0001] The invention relates to the field of ball bearing outer groove grinding machine processing, in particular to a lateral feed device for outer groove cutting grinding machine equipment. (2) Background technology

[0002] 3MZ1410 automatic plunge-cut grinding machine for external grooves is used for processing the raceways of the outer rings of small ball bearings. The processing range is φ30-φ100mm, which is a fully automatic grinding machine for batch processing of bearing rings. The feeding part of the machine tool adopts the static pressure guide rail, the machine tool has been used for a long time, the static pressure guide rail is difficult to repair, the performance of the machine tool is reduced, the machining accuracy is low, and it is difficult to ensure the accuracy of the bearing ring. Compensation and working are a combination of hydraulic pressure and rack and pinion with complex structure, which is not only easy to wear, but also has ...
