Numerical control milling machine for machining artillery pipe rifle

Abstract

The invention belongs to the technical field of milling machine devices, and particularly relates to a numerical control milling machine for machining an artillery pipe rifle. The numerical control milling machine comprises a pipe machine body used for supporting a pipe positioning and clamping part and a machine tool spindle body connected with a supporting pipe milling part. Dovetail groove guide rails arranged on the pipe machine body are connected with a front support, a rear support, a front oil collecting tank and a rear oil collecting tank. Linear roller guide rails arranged on the machine tool spindle body are connected with a Z-axis feeding mechanism and a C-axis rotation feeding mechanism. The C-axis rotation feeding mechanism is connected with a milling cutter system. The machine tool spindle body is connected with an operating floor and a fixed guide rack. The feeding mechanisms can be controlled to generate rifling trajectories and torque through a control system consisting of the operating floor and an electric control cabinet, the milling cutter system is controlled to output cutting force and torque, and finally the artillery pipe rifle can be milled. The numerical control milling machine is high in machining precision, good in surface quality, high in production rate, high in safety, good in reliability, easy to adjust and low in maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of milling machine devices, and in particular relates to a numerically controlled milling machine used for processing gun barrel rifling. Background technique [0002] Compared with smoothbore weapons, rifled weapons have high long-range accuracy, stable and convenient projectiles, and are suitable for different external ballistic requirements. It has been widely used since its invention. [0003] The specifications of the rifling include the structure and number of the rifling, the width of the male and female rifling, the depth of the female rifling, the winding degree of the rifling and other indicators; the rifling is divided into rectangle, trapezoid, circular arc, multi-arc, polygonal arc and bow according to the cross-sectional shape Rifling is divided into equal rifling and gradual rifling according to the change of winding degree, and it is divided into cylindrical rifling and conical rifling accor...

AI Technical Summary

Problems solved by technology

But the production efficiency is low, the surface of the female rifling is rough and there are knife marks, the internal ballistic resistance after processing is large, the shape of the broach is complex and the manufacture is difficult

[0005] Therefore, the broaching method is difficult to guarantee the accuracy and high efficiency of the gun barrel rifling processing, and there are problems such as low productivity, low precision, and poor stability.
