Problems solved by technology

[0002] At present, most of the CNC turning and milling compound machine tools produced at home and abroad share the same spindle for turning and milling cutters. During turning and milling processing, it is necessary to switch between the turning and milling states of the tool spindle. The structure is more complicated. , In the four-axis control of C-axis, only three-axis linkage can be realized; complex processing programs need to be compiled during processing, which requires high comprehensive quality and technical level of the operator

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the schematic structural diagram of the invention and specific embodiments.

[0017] The bed 16 of the machine tool adopts an integral floor type, and there is only one main shaft 2 in the bed head box of the machine bed, and the main motor of the machine tool adopts a high-performance servo main shaft motor, which is transmitted to The spindle 2 inside the bedside box 1 has a spindle speed range of 10 to 800r / min, which can realize stepless speed regulation and constant speed cutting, with small temperature rise and thermal deformation. The spindle has a C-axis function that can be accurately indexed. Accuracy up to 3'. The lower block 9 is housed on the machine tool saddle 3, and the rear end of the lower block 9 is equipped with a liftable milling power head 6, and the lifting of the milling power head 6 is realized by the rotation of the ball screw pair 11 driven by the servo motor 7. The mil...

Abstract

The invention discloses a digital control turning-milling complex machine tool, which comprises a digital control machine tool body, a spindle system, a milling unit head, a cutting off tool rest, a tailstock, a longitudinal and horizontal feed system and a lubricating system, and is characterized in that a lower slide block is arranged on a saddle of the machine tool; the front end of the lower slide block is provided with the four-station electric cutting off tool rest; the back end of the lower slide block is provided with the milling unit head capable of lifting; a mill head spindle of the milling unit head is provided with a milling cutter or a drill bit; the lifting of the milling unit head is realized by a servo motor driving a ballscrew pair to rotate; and a variable-frequency motor drives the mill head spindle to rotate, and the rotating speed of the mill head spindle is changed through adjustment of the frequency of the variable-frequency motor. Through once clamping, the digital control turning-milling complex machine tool can realize turning-milling complex processing to achieve the aim of multiple functions of one machine; the machine tool realizes four-axis linkage controlled by four axes combined by an X axis, a Y axis, a Z axis and a C axis together through a digital control system; and the whole machine has good rigidity, and the dimensional precision of processed parts reaches IT 7 and the surface roughness Ra is less than or equal to 3.2 mu m.

Description

technical field [0001] The invention relates to a numerical control turning and milling compound machine tool. Background technique [0002] At present, most of the CNC turning and milling compound machine tools produced at home and abroad share the same spindle for turning and milling cutters. During turning and milling processing, it is necessary to switch between the turning and milling states of the tool spindle. The structure is more complicated. 1. In the four-axis control of the C-axis, only three-axis linkage can be realized; complex processing programs need to be compiled during processing, which requires high comprehensive quality and technical level of the operator. Contents of the invention [0003] The purpose of the present invention is to provide a numerically controlled turning-milling compound machine tool with simple structure, which can realize the combined turning, milling and drilling of the machine tool through one-time clamping on the lathe. [0004...
