Abstract

The invention discloses a tool for turning a rear cover shell. An inner hole of a rotating indexing disc is installed on a shaft through a single-row tapered roller bearing, moreover, the rotating indexing disc is installed on the upper surface of a mounting plate of a turning device body through a fixing bolt, after the fixing bolt is disassembled, the rotating indexing disc can rotate around theshaft; a workpiece clamping seat is fixed on the upper surface of the rotating indexing disc, two indexing pins are installed in indexing grooves located in the mounting plate of the turning device body correspondingly. According to the tool, machining of two perpendicular intersection hole systems can be achieved, moreover, form and position tolerance of two axes is guaranteed through the turning device, the production efficiency and the precision of the form and position tolerance are improved; moreover, turning of the two perpendicular intersection hole systems, an end surface and an outercircle can be completed through the rotating indexing disc, turning of two or more hole systems with different included angle and axes intersected, the outer circle, the end surface, threads, a conical surface and the like can also be completed, and the tool is suitable for machining two or more than two hole systems with any included angle.

Description

technical field [0001] The invention relates to a turning processing device for a rear cover shell and a turning device for mutually perpendicular hole systems, outer circles and end faces, and is widely used in the fields of aviation, aerospace and chemical industry. [0002] technical background [0003] At present, in the metal shell of space rocket engine, the back cover shell is also one of the important parts. High, according to the functions and manufacturing technology of various machine tools, lathes are used to process holes, end faces, outer circles, cones, threads, etc. in a certain shaft system, while holes and end faces in another vertical axis , outer circle, tapered surface, thread, etc. can only be processed by CNC boring and milling machine. In order to ensure the shape and position tolerance and processing size of the axis, it is necessary to align and measure the axis that has been processed. The processing datum and measuring datum of the axis make the m...
