Abstract

The invention belongs to the technical field of broacher devices, in particular to an automatic backlash-eliminating dividing device used for a numeral control helical deep hole broacher. The device comprises a box body, an alternating current servo motor, an input-output mechanism, and a circular grating detection mechanism. In the device, scale division is controlled directly through the alternating current servo motor; and through pushing a driving axle to glide axially by an adjusting washer and a disc spring, the driving axle and a double-tooth backlash-eliminating mechanism consisting of driven wheels can automatically compensate to eliminate backlashes after a gear is worn. The driving device of the invention has the advantages of low cost and maintenance cost, high safety, and good reliability.

Description

technical field [0001] The invention belongs to the technical field of broaching machines, and in particular relates to an automatic backlash-removing indexing device for a numerically controlled spiral deep-hole broaching machine. Background technique [0002] The general-purpose CNC spiral deep hole broaching machine is formed by the template, and the spindle is indexed by the rack and pinion transmission. First of all, the mechanism of the template is relatively complicated and occupies a large space. Often, a large number of cumbersome calculations and adjustments are required when processing and replacing products. And the accuracy is not easy to guarantee; secondly, the transmission mode of the rack and pinion pair has the characteristics of large horizontal space occupation and low accuracy. [0003] Therefore, it is difficult to guarantee the diversity and accuracy of deep hole helix processing by using traditional indexing mechanisms, resulting in low productivity, ...
