Abstract

The invention belongs to the technical field of broaching machine devices, and in particular relates to a numerically controlled deep hole broaching machine used for gun barrel rifling and receding bar variable cross-section grooves, including a workpiece bed for positioning workpieces and supporting clamping components, and is also connected with The tool bar bed is used to support the broaching parts of the workpiece; the tool bar bed is connected with a roller linear guide, a fixed guide frame, and an operation box, and the roller linear guide is connected with a follow-up guide frame, a The feeding system controls the output tension and torque of the feeding system through the control system composed of the operation box and the electric control cabinet, and finally completes the broaching of the rifling of the gun barrel and the variable-section groove of the retracting rod through the broaching system. The broaching machine of the present invention has high precision, high productivity, high safety, good reliability and low maintenance cost.

Description

Technical field The invention belongs to broaching device technical field, be specifically related to a kind of for cannon barrel rifling and retreat rod variable section Groove CNC deep hole broaching machine. Background technique Traditional cannon barrel rifling and receding bar variable cross-section groove are processed using profiling broaching machine, and its mechanism is complicated, precise The degree can barely meet the requirements. In particular, the indexing function actually consists of fitting the helical line or the expanded line of other curves by the template, and then The main shaft indexing is carried out by the rack and pinion pair or the worm gear pair. Firstly, the mechanism of the template is relatively complicated and takes up a large space. Often when processing and replacing products, a large number of tedious calculations and adjustments are required, and the accuracy is not easy to guarantee; secondly, the rack and pinion The transmissi...
