Embodiment Construction

[0038] Below in conjunction with accompanying drawing, the patent of the present invention is described in further detail.

[0039] Gear processing usually has very strict requirements on two or more relative motion speeds, and there should be no relative error in the position of each other during the motion process. Traditional gear hobbing machines use complex gear transmission chains to achieve precise generative motion. The electronic gearbox uses computer control technology to realize high-precision and high-efficiency fixed-ratio and variable-ratio gear processing, replacing the cumbersome generation and differential mechanical transmission chains of traditional gear machine tools, and realizing a variety of complex motion mechanisms with simple functional relationships. The CNC gear hobbing machine tool has six CNC axes, namely the radial feed axis X axis, the tool movement axis Y axis, the axial feed axis Z axis, the hob installation angle adjustment axis A axis, the ho...

Abstract

The invention discloses a high-speed high-precision flexible electronic gear box control method based on an open numerical control system. An electronic gear box is a core part of a gear processing numerical control system, and by parameter setting, requirements, on multi-axis linkage strict speed ratio relationships, of different machine tools for gear hobbing, gear grinding and the like can be met. Each axis servo motor and a spindle motor are connected with the system through motor interfaces, main movement signals are fed back through a motor encoder or a grating ruler, processed by the numerical control system and distinguished and computed through the flexible electronic gear box, and follow-up numerical control shafts are controlled to complete master-slave electronic gear ratio movement.

Description

technical field [0001] The invention belongs to the technical field of motion control, in particular to a motion control method with multi-axis coupling relationship. Background technique [0002] There are extremely strict requirements between two or more relative motion speeds connected by the inline transmission of CNC gear processing machine tools. The traditional CNC system uses interpolation algorithm to obtain multi-coordinate linkage motion commands, but because the dynamic accuracy and static accuracy of each coordinate axis cannot be consistent, it cannot meet the requirements of inline transmission. The appearance of the electronic gearbox makes the complex mechanical transmission system extremely simple; especially in the current software electronic gearbox, computer software replaces the mechanical connection, which greatly improves the flexibility and transmission accuracy of the machine system. Now foreign CNC systems such as Siemens 840D or FANUC16i / 18i seri...
