Five-axis linkage blade processing machine tool with automatic workpiece clamping and its clamping method

Abstract

The invention provides a five-axis linkage blade processing machine tool with an automatic workpiece clamping function and a clamping method of the five-axis linkage blade processing machine tool. The machine tool comprises a workpiece shaft, a workbench, a vertical column, a tool spindle and a machine tool body, wherein the workpiece shaft comprises a head frame and a tail frame and is fixed on the workbench; the workbench is arranged on the machine tool body; the workpiece shaft and the workbench move on the machine tool body in the X-axis direction of the machine tool; the tool spindle is arranged on the vertical column and moves on the vertical column in the Z-axis direction of the machine tool; the vertical column is arranged on the machine tool body; the tool spindle and the vertical column move on the machine tool body in the X-axis direction of the machine tool; an automatic clamping mechanism is arranged in the center of a rotating shaft of the head frame; an automatic pushing mechanism is arranged at the bottom of the tail frame. A blank and a finished workpiece product can be automatically clamped through manual operation or manipulator operation, the processing accuracy of the workpiece is improved, and the processing cost of the workpiece is reduced.

Description

technical field [0001] The invention relates to metal cutting equipment, in particular to a five-axis linkage blade processing machine tool with automatic workpiece clamping and a clamping method thereof. Background technique [0002] The five-axis linkage blade processing machine tool is a special machine tool for processing blades or narrow and long parts with complex spatial surfaces, and has been widely used in power generation, ships, aerospace and other fields. [0003] The existing five-axis linkage blade processing machine tools mostly adopt the layout mode of three linear coordinate axes and two rotary coordinate axes, which can realize five-axis linkage CNC interpolation machining. At present, manual clamping is often used to fix the blank to be processed on the workpiece axis, that is, firstly, the clamping part is fixedly connected with the workpiece axis of the machine tool (axis A of the rotary coordinate axis), and the blank is placed manually before each mach...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned manual clamping method has the following defects: First, the manual loading of the blank and unloading of the workpiece increases the auxiliary processing time occupied by the machine tool

Since the five-axis linkage blade processing machine tool is a high-end machine tool, the cost is expensive, so the increase in auxiliary processing time will increase the cost of the machine and manpower, thereby increasing the processing cost of the parts; the second is that the human factor of manual clamping has a great influence , the clamping effect of different operators is different, even if the same operator clamps each time, it will obviously cause poor consistency of clamping, and affect the processing accuracy and processing efficiency at the same time, hindering the batch processing of workpieces
