Four-axle turn-mill combination vertical processing center

Abstract

The invention provides a four-axle turn-mill combination vertical processing center. The rear part of a lathe bed is provided with a movable column capable of performing X-Y-Z three-dimensional motion; the movable column is provided with a main shaft assembly; a box body of the main shaft assembly is internally provided with a main motor and a main shaft which are connected with each other; a vertical feeding device is arranged between an upright column and the box body of the main shaft assembly; a truncated cone hole-shaped tool shank spigot is arranged on a shaft head at the lower end of the main shaft; the lathe bed is provided with a numerical control device and a tool library device; a turning tool positioning base is connected beside the truncated cone hole-shaped tool shank spigot at the lower end of a main shaft box body; a workbench at the front part of the lathe bed is an electric main shaft which is parallel to the main shaft and is provided with a brake; the upper end of the electric main shaft is connected with a clamping chuck for clamping a workpiece. The workbench is provided with the electric main shaft which is vertical to the horizontal direction; the upper end of the electric main shaft is connected with the clamping chuck for clamping the workpiece, and the electric main shaft is a C shaft for providing rotation to the workpiece; the turning tool positioning base is connected beside the truncated cone hole-shaped tool shank spigot at the lower end of the electric main shaft box body; by virtue of cooperation between the turning tool positioning base and a turning tool sleeve, after the workpiece is clamped once, not only can milling be performed on the workpiece, but also turning can be performed on the workpiece.

Description

technical field [0001] The invention relates to a vertical machining center, in particular to a workbench of the vertical machining center. Background technique [0002] A machine tool is a device that cuts a metal workpiece with a tool. The machine tool has a clamping tool device and a clamping workpiece device. During cutting, the tool and the workpiece must move relatively. According to the motion state of the tool and the workpiece, cutting processing includes turning processing and milling processing. Turning processing is when the tool is fixed and the workpiece is rotated, and milling is when the workpiece is fixed and the tool is rotated. [0003] Vertical machining center is a highly automated CNC milling machine with CNC system, tool magazine and automatic tool changer. The bed of the vertical machining center has a column connected to the spindle box, a worktable, a feeding device, an automatic tool changer and a numerical control device. When in use, formulate...

AI Technical Summary

Problems solved by technology

This kind of vertical machining center can only perform milling processing on the workpiece, and cannot perform turning processing on the workpiece. If the workpiece requires both turning and milling processing, the workpiece must be clamped and cut on the lathe and milling machine respectively.

Not only labor-intensive and time-consuming, but also affect the precision of processed products

[0008] In the prior art, there is no turn-milling compound vertical machining center that can perform both milling and turning on the workpiece after the workpiece is clamped once.
