Large-power turning and milling composite machine tool

Abstract

The invention discloses a large-power turning and milling composite machine tool, belongs to the technical field of machine tools, and aims to solve a problem in a traditional composite machine tool that a milling device is only used for auxiliary machining. The key point of the technical scheme is that the large-power turning and milling composite machine tool comprises a lathe bed, a main shaftinstalled on the lathe bed, a back face knife table installed at one side of the main shaft, and the milling device installed at the other side of the main shaft. The milling device comprises a driving mechanism and a milling mechanism rotatably installed on the driving mechanism. The large-power turning and milling composite machine tool is capable of, through installing the milling device with aB-axis on the lathe bed, and enabling the milling device to be rotated in multiple degrees, completing the milling and machining of a complicated workpiece by cooperating with the main shaft, effectively shortening a product manufacturing process chain, improving production efficiency, reducing a clamping frequency of the workpiece, and effectively improving machining precision, and further has the advantages of reducing floor area, and reducing production cost.

Description

technical field [0001] The invention relates to the technical field of machine tools, more specifically, it relates to a high-power turning-milling compound machine tool. Background technique [0002] A machine tool is a device that mainly uses a turning tool to turn a rotating workpiece. The machine tool is mainly composed of a supporting component, a speed change mechanism, a feed mechanism, a spindle box, and a lubrication system. Most of the traditional machine tools have single functions, some are mainly for turning processing, and some are mainly for milling processing. When it is necessary to perform both turning and milling operations on the workpiece, the workpiece needs to be replaced on a machine tool with different functions for processing. This traditional operation will inevitably lead to too many clamping times of the workpiece, and the corresponding machining accuracy will also be affected. Moreover, due to frequent replacement of the workpiece position, the ...

Problems solved by technology

Most of the traditional machine tools have single functions, some are mainly for turning processing, and some are mainly for milling processing. When it is necessary to perform both turning and milling operations on the workpiece, the workpiece needs to be replaced on a machine tool with different functions for processing. This traditional operation will inevitably lead to too many times of clamping the workpiece, and the corresponding machining accuracy will also be affected. Moreover, due to frequent replacement of the workpiece position, the debugging time will increase accordingly, resulting in low production efficiency.

[0003] In order to overcome the above problems, in the prior art, the transformation is usually completed on the turning center. The general method is to replace the ordinary turret of the CNC lathe with a turret with a powered tool, and add the C-axis function to the main shaft. Due to the limitations of the power head, the power of the power head is small, the speed is not high, and it cannot be installed with larger tools. Therefore, this type of machining center is mainly for turning processing, and the milling and drilling functions are only for some auxiliary processing.

Therefore, high-power processing cannot be achieved for some workpieces
