AC linkage double-swing head of five-axis machine tool

Abstract

The invention relates to the technical field of five-axis machine tool accessories, in particular to an AC linkage double-swing head of a five-axis machine tool. The AC linkage double-swing head comprises an A-axis shell; a first sealing cover and a second sealing cover are respectively arranged on the outer walls of the two sides of the A-axis shell through bolts; a top plate is arranged on the outer wall of the top of the A-axis shell through bolts; a C-axis connecting base is welded to the axis of the outer wall of the top of the top plate; a C-axis flange plate is installed on the outer wall of the top of the C-axis connecting base through bolts; a C-axis connecting disc is installed on the outer wall of the top of the C-axis flange plate through bolts; and a first bearing is embeddedinto the axis of the C-axis connecting disc. The AC linkage double-swing head has the beneficial effects that double-piston calipers are connected with a C-axis brake disc, so that when the double-piston calipers of the C-axis part of the AC five-axis linkage double-swing head are locked, the acting force of the double-piston calipers is applied to the C-axis brake disc, the geometric accuracy ofa bearing cannot be influenced, and the bearing can be well protected; therefore, the service life is prolonged, and the positioning precision and the working efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of five-axis machine tool accessories, in particular to an AC linkage double swing head of a five-axis machine tool. Background technique [0002] Five-axis linkage CNC machine tool is a machine tool with high technological content and high precision specially used for processing complex curved surfaces. Has a significant influence. At present, the five-axis linkage CNC machine tool system is the only means to solve the processing of impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, large diesel engine crankshafts, etc. [0003] After retrieval, Chinese Patent No. CN207982390U provides a high-speed AC five-axis linkage double swing head, including a C-axis motor, an A-axis motor and an electric spindle. One end of the output shaft of the C-axis motor is provided with a C-axis reducer. The C-axis One surface of the shaft reducer is provided with a C-axis connection plate, o...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an AC linkage double swing head of a five-axis machine tool to solve the problem of adopting an embracing locking method proposed in the above-mentioned background technology, and a large part of the force of this locking method is used on the bearing, which is very difficult. It is easy to cause axial and radial deformation of the bearing, and it is easy to cause displacement, which leads to bearing wear and affects the accuracy index of the AC axis, resulting in poor service life, poor positioning accuracy and reduced work efficiency.
