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
[0006] 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.

Abstract

The invention belongs to the technical field of milling machine devices and specifically relates to a milling cutter system. The milling cutter system comprises a support cylinder, a spindle motor, cages, a main gear and a milling cutter apparatus. The support cylinder and a knife bar are connected through a flexible shaft coupling. Two ends of the support cylinder are both fixedly connected witha cage, which is used for keeping the support cylinder and the inner wall of a barrel to be contacted and keeping rotation center lines of the support cylinder and the barrel to be coaxial. A stator of the spindle motor is fixedly connected with the inner wall of the support cylinder. The main gear and a rotor are fixedly connected. Through the milling cutter, it is ensured that cross-section shape and size of barrel rifling are consistent, and changes of rifling depth and shape due to deformation of the knife bar by force will be avoided.

Description

[0001] This application is a divisional application with the application number 2017107297667, the application date of August 23, 2017, and the title of the invention "a CNC milling machine for rifling processing of artillery barrels". technical field [0002] The invention belongs to the technical field of milling machine devices, and in particular relates to a milling cutter system. Background technique [0003] 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. [0004] 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-sect...
