Oblique lathe bed double-spindle and double-row-tool numerical control lathe capable of achieving automatic feeding and discharging inside

Abstract

The invention discloses an oblique lathe bed double-spindle and double-row-tool numerical control lathe capable of achieving automatic feeding and discharging inside. A lathe bed is provided with a left spindle box and a right spindle box which are oppositely arranged. Spindle units are arranged in the spindle boxes. Material clamping devices are arranged at the front ends of the spindle units. The spindles are connected with spindle power main servo motors through belts. A left saddle and a right saddle are arranged on the lathe bed in the Z direction in parallel and can move left and right in the Z direction. Sliding plates are arranged on the left saddle and the right saddle and move in the X direction in the corresponding saddles. The left spindle box and the right spindle box are symmetrically arranged with the center of the lathe bed as the symmetric face, the saddles are symmetrically arranged with the center of the lathe bed as the symmetric face, the sliding plates are symmetrically arranged with the center of the lathe bed as the symmetric face, and row tool plates are symmetrically arranged with the center of the lathe bed as the symmetric face. An automatic lathe interior feeding and discharging mechanism is arranged on the lathe bed and the spindle boxes, a scrap discharging box is arranged at the bottom of the lathe bed, outer protection parts are arranged on the lathe bed, and spindle control system double CRT boxes are fixed to the outer protection part. Accurate machining in all procedures including bearing ring inner circles, outer circles, end faces, chamfers, grooves, dustproof grooves and the like is finished on one machine tool, original machining procedures of several machine tools are combined to be conducted on one machine tool, the occupied area is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to machine tool manufacturing in mechanical processing, and is a special numerical control machine tool specially developed for processing bearing rings. Background technique [0002] At present, when processing small bearing rings in China, most of them use semi-automatic hydraulic lathes, and one bearing ring workpiece is processed sequentially by several hydraulic lathes. The hydraulic lathes are troublesome to adjust, the process is scattered, the floor space is large, the equipment has no protection, and the degree of environmental pollution is high. , The degree of automation is low, which affects the precision requirements of the processed workpiece. Contents of the invention [0003] The purpose of the present invention is to provide a double-spindle, double-row knife, automatic loading and unloading lathe in the machine, so as to realize the inner circle, outer circle, end face, chamfer, groove, dust-proof groove, etc. ...
