Embodiment Construction

[0033] The basic principle of the dual-axis synchronous control device of the CNC machine tool is: after the synchronous control device receives the CNC pulse command, it forwards it to the two synchronous synchronous axes (X1 axis and X2 axis, X axis is taken as an example in the text) in real time, and at the same time Count the position feedback signals of the two axes, and calculate the position deviation of the two synchronous axes, and adjust the number of pulses of the driven axis (X2 axis) within a certain range according to the deviation, so as to realize the output position of the two motors synchronous control. Below in conjunction with accompanying drawing and example the present invention is described in further detail.

[0034] Such as figure 1As shown, it is a block diagram of the connection between the dual-axis synchronous control device of the CNC machine tool and the numerical control system; after adding the dual-axis synchronous control device 1, for the ...

Abstract

The invention discloses a digit control machine double-shaft synchronization control device, comprising a clock, an input and output interface, a double-shaft position check module, a control unit, a system parameter list and a pitch compensation list, wherein the double-shaft position check module processes position and synchronization error check for two synchronous shaft motor encoders and provides the check information to the control unit, the control unit selects a working mode corresponding to the parameters of the system parameter list, according to the position and error information of the two synchronous shafts provided with the double-shaft position check module and the process corresponding to the selected working mode, the control on the two synchronous shafts can be realized. The invention resolves the problem of the common digit control system which can not realize synchronous control, realizes the real-time character between transfer and adjustment, avoids the profile error of processed elements caused by delayed transfer time, and avoids the serious dynamic synchronous error caused by long adjustment.

Description

technical field [0001] The invention belongs to numerical control technology, and in particular relates to a dual-axis synchronous control device for a numerical control machine tool. Background technique [0002] In the linear movement of the gantry of the large-span gantry machine tool driven by two axes, the two-column linear movement of a large three-coordinate measuring machine, and some horizontal machining centers driven by two axes, in order to avoid the deflection of moving parts, it is necessary to use The motion of the servo-driven motors for the two axes is synchronized. Due to machining errors and assembly errors, there is always a certain asymmetry in the structure of large moving parts; there is always uncertainty and imbalance in the load during machining operations. In addition to the mechanical coupling, even if the same transmission mechanism is used on both sides, it is inevitable that there will be inconsistencies in operation, which will lead to the de...
