Special bidirectional automatic turning machine

Abstract

The invention provides a special bidirectional automatic turning machine. A tool rest is fixedly arranged on a lathe bed; a first spindle and a first transverse and longitudinal moving mechanism for driving the first spindle to move transversely and longitudinally is arranged on the left side of the tool rest; and a second spindle and a second transverse and longitudinal moving mechanism for driving the second spindle to move transversely and longitudinally is arranged on the right side of the tool rest. The special automatic turning machine further comprises a feeding mechanism, a pushing structure and a discharging mechanism. The special bidirectional automatic turning machine is high in automation degree, and labor intensity of people is reduced. After one end of a workpiece in a firstspindle chuck is machined, the workpiece is conveyed into a second spindle chuck through the moving and butt joint functions of the first spindle and the second spindle, and the other end of the workpiece in the second spindle chuck is machined, so that the two ends of the workpiece are machined through one-time clamping. Moreover, when the other end of the workpiece on the second spindle is machined, one end of a next workpiece on the first spindle can be machined at the same time, that is, the two workpieces can be machined at the same time, and the machining efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a bidirectional automatic turning machine. Background technique [0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. When the ordinary turning machine tool processes the outer wall and both ends of the shaft or disk workpiece, it can only be processed in one direction, that is, the part clamped by the spindle chuck cannot be processed; if the workpiece needs to be processed in two directions, the workpiece can only be processed After one end is cut and processed, turn around and clamp again before cutting the other end; for the operator, two-way processing requires two clamps, which makes the work intensive and inefficient. Furthermore, the loading and unloading of ordinary lathes are all done by operators, which has a low degree of automation, low efficiency and high labor costs. Contents of the invention ...
