Special lathe for ultraprecise automatic processing of hollow shaft

Abstract

The invention relates to a special lathe for ultraprecise automatic processing of a hollow shaft. Two ends of a lathe body are coaxially provided with two electric spindles. A feeding mechanism is installed in front of the electric spindles. Through the feeding mechanism, a workpiece is accurately fed. A clamping device is installed beside the feeding mechanism. A motor and a cam transmission shaft are installed below the lathe body. The motor is in the transmission connection with the cam transmission shaft. The cam transmission shaft is provided with a transmission mechanism formed by multiple cams, successively used for controlling the movement of the clamping device, a feeding plate, a detaching plate, and the electric spindles, and realizing the processing for the end face of an aluminum pipe. The special lathe uses an electric spindle technology, so that the headstock structure of the lathe is compact. Eight cams are used for driving each actuating element, the full automation of whole machine is implemented, and the structure is simple and reliable. The workpiece is clamped by using the self-alignment, the over-positioning and the uneven clamping force are avoided in the clamping process of the workpiece, and a fine adjustment mechanism is installed to satisfy the needed clamping force. An automatic overturning device is used for realizing the automaton of feeding and blanking, and the working efficiency and the reliability are improved.

Description

technical field [0001] The invention relates to a special machine tool for ultra-precision machining of the end faces of pipe shaft parts, in particular to a special machine tool which can complete the turning work of both end faces of pipe shaft parts and internal and external chamfering at one time. Background technique [0002] Thin-walled aluminum alloy pipe fittings used in printers, copiers and other equipment have the characteristics of light weight, large demand, and high requirements for size and position accuracy. At present, the equipment used for reprocessing the end faces of such pipe fittings often has the following problems: [0003] 1. Imported equipment can process products that meet the precision requirements, but the equipment price is too high. [0004] 2. The quality of pipe fittings processed by domestic machine tools is unstable, and the qualified rate of products is low; the installation, positioning and clamping of pipe fittings during processing ...
