Abstract

The invention belongs to the technical field of broaching machine, in particular relates to a protective device used for circular grating of numeric control deep hole broaching machine. The reading head mounting base of the protective device is taken as the mounting base plane of a reading head; the spindle is connected with a transition flange to output power; the guide screw can cause a seal cover not to damage a grating bar; the reading head mounting base, the spindle, the seal cover, an O-shaped seal ring and the transition flange form a sealed space, thus providing protection for the circular grating; the discharging hole and a closing plug discharge lubrication liquid permeated into the sealed space of the circular gratin; and the reading head and the grating bar form a circular grating detection mechanism, so as to provide a closed loop detection feedback signal. The protective device of the invention has low cost, good reliability and low maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of broaching machines, and in particular relates to a protective device for a circular grating of a numerically controlled deep hole broaching machine. Background technique [0002] The rotation accuracy of the CNC deep hole broaching machine when processing deep holes requires a high-precision measuring device feedback signal to achieve closed-loop control to ensure. At present, due to the structural limitations of the broaching machine itself, large-diameter circular gratings are required and products with high enclosure protection levels are difficult to import. The actual use is circular gratings without enclosure protection. The grating scale of the circular grating must be protected by special measures, otherwise the measurement accuracy will be lost once the grating scale is polluted. Contents of the invention [0003] In order to solve the problem of the protection of the circular grating above, t...
