Vertical grinding-turning compound machine tool

Abstract

The invention relates to a vertical grinding-turning compound machine tool. The vertical grinding-turning compound machine tool is characterized in that a stand column is fixed to a machine tool body,and a cross beam is fixed to the stand column; a turning saddle is connected with the cross beam through a horizontal linear guide rail and is driven by a turning X-axis drive mechanism; a turning tool rest mechanism is connected with the turning saddle through a vertical linear guide rail and is driven by a turning Z-axis drive mechanism; a turning tool shank is arranged below the turning tool rest mechanism; a grinding saddle is connected with the cross beam through a horizontal linear guide rail and is driven by a grinding X-axis drive mechanism; a grinding spindle mechanism is connected with a sliding seat through a linear guide rail and is driven by a grinding Z-axis drive mechanism; a rotating disc type locking mechanism is connected between the middle of the sliding seat and the grinding saddle, the center of the rotating disc type locking mechanism is a B-axis rotating center for swinging of the sliding seat, and a grinding B-axis swing angle driving mechanism is connected between the upper end part of the sliding seat and the grinding saddle. The machine tool achieves one-time workpiece clamping, improves the machining efficiency and guarantees the workpiece precision.

Description

technical field [0001] The invention belongs to the technical field of machine tools, and in particular relates to a vertical grinding and turning compound machine tool. Background technique [0002] Disc, ring and sleeve parts are common part structures in mechanical equipment. These parts are usually processed by turning first, and then precision grinding. The existing processing methods usually adopted are: turning is completed on an ordinary or numerically controlled lathe, and grinding is processed on a grinding machine. This processing method requires secondary clamping, which will affect processing efficiency and processing accuracy. In order to improve the processing efficiency, some processing enterprises adopt the method of adding a grinding spindle on the basis of the structure of the vertical lathe, so that the workpiece can be clamped at one time, which can improve the processing efficiency, but affected by the accuracy of the lathe, the grinding of the workpiec...
