Erected-inverted machine tool with double spindles and double knife towers

Abstract

The invention provides an erected-inverted machine tool with double spindles and double knife towers, and belongs to the field of numerically-controlled machine tools. The erected-inverted machine tool with the double spindles and the double knife towers comprises a machine body, wherein an installation platform is horizontally arranged on the machine body along the X axis; an X-axis guide rail ishorizontally arranged on the installation platform; a first vertical column and a second vertical column are sequentially vertically arranged above the installation platform; a first drive part driving the first vertical column to move along the X-axis guide rail, and a second drive part driving the second vertical column to move along the X-axis guide rail are further arranged on the machine body; a first spindle part is arranged on the first vertical column; a second knife tower part is arranged on the second vertical column; a first knife tower part is arranged on a part located at one side of the first spindle part, of the machine body; and a second spindle part is arranged on a part located between the first vertical column and the second vertical column, of the machine body. The erected-inverted machine tool with the double spindles and the double knife towers has the functions of automatically loading, automatically machining and automatically unloading, and is high in automation degree; the erection and the inversion of the machine tool are combined, and overturning is not needed during workpiece machining, so that continuous production can be carried out; the X-axis guiderail is horizontally arranged, so that more stable movement and high machining accuracy are achieved; and moreover; the mechanisms of the machine tool are compact in structure, and the machine tool is compact in overall layout.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to a double-spindle and double-turret upside-down lathe. Background technique [0002] With the revitalization and development of the national equipment manufacturing industry, CNC lathes, as the mainstream product of the lathe industry, have become the key equipment to realize the modernization of the equipment manufacturing industry. [0003] The upside-down lathe is one of many lathes. The upside-down lathe has a large output torque of the spindle and is mainly used in the automotive industry, especially for the processing of disc parts such as wheel hubs and brake discs. The turret of the upside-down lathe does not move when processing the workpiece, and the integrated fixture on the spindle holds the workpiece. When turning, the spindle drives the workpiece to rotate and move to complete the turning. [0004] As shown in the patent No. CN204770699U named automatic forward and reve...

Problems solved by technology

In the above structure, the carriage is hung on the side of the bed. Since the main shaft and the turret are heavy and the power drive unit is integrated, the pressure on the guide rail is very large when the carriage moves and the main shaft and turret work, which easily causes deformation of the guide rail. , and the unstable movement of the spindle and turret, which affects the machining accuracy
