Additional device with A and B-axis oscillating structure and manufacturing method thereof

Abstract

The invention relates to an additional device with an A and B-axis oscillating structure and a manufacturing method thereof. The additional device is used for five-axis linkage machining, and is characterized in that: a B-axis structure is fixed to the upper side of a sliding plate, a B-axis large gear ring is fixed with a B-axis support, and the B-axis support rotates around an oscillating shaft to form a B axis; an A-axis structure is fixed on the right side of the B-axis support; a main shaft box is fixed between two arms of the B-axis support; an A-axis large gear ring is fixed with the main shaft box; a left revolving shaft and a right revolving shaft are respectively, axially and horizontally fixed on the main shaft box; and the main shaft box rotates synchronously on a left shaft sleeve and a right shaft sleeve respectively to form an A axis; and thus, the additional device is formed. In the integral design of the device, the A axis allows for oscillating + / -30 degrees around an X axis, the B axis allows for oscillating + / -30 degrees around a Y axis, and the A axis and the B axis are subjected to closed-loop control by a circular grating; and the position control function of a computerized numerical control (CNC) system is realized by software and circuit hardware serving as electrical appliance circuits. In the device, three straight line axes of X, Y and Z are subjected to linkage to machine a complex space curved surface, so the device has the characteristics of compact structure, high accuracy and rigidity, large torsion and the like.

Description

technical field [0001] The invention relates to an additional device for swinging head structures of A and B axes in machine tools of mechanical manufacturing equipment, which is used for five-axis processing equipment. technical background [0002] In the domestic CNC machine tool market, domestic enterprises have a small share, and their products are mainly concentrated in the field of low-end CNC machine tools such as economical and ordinary models. occupied by. The current situation of the machine tool industry has led to the fact that my country's aviation structural parts CNC machining equipment has been mainly imported from abroad for a long time, especially high-tech key equipment such as five-axis machining with A and B-axis swing head structures is close to 100% dependent on imports. Since the purchase of such equipment must apply for a license from the country where the equipment is produced, the availability of equipment is greatly affected by international poli...
