Embodiment 1

[0076] Embodiment 1 A control system for a measuring device for accuracy retention of rolling functional parts of a machine tool, which measures the accuracy retention of rolling functional parts of a machine tool based on the measuring device for accuracy retention of rolling functional parts of a machine tool;

[0077] (1) The measuring device for accuracy retention of machine tool rolling function parts is composed of the following: bed 1, tested guide rail 2, tested screw 3, workbench 4, servo motor for screw 5, coupling for screw 6, implement The force component 7; wherein: the bed 1 is a horizontal structure; the tested guide rails 2 are two arranged parallel to each other in the horizontal direction, and are fixedly arranged on the upper part of the bed 1; the tested screw 3 is driven by its dedicated driving component; The workbench 4 is arranged on the tested guide rail 2 and the workbench 4 is driven by the tested lead screw 3 and can move on the tested guide rail 2; ...

Embodiment 2

[0186]The control of the force exerting mechanism is basically the same as that of the scheme 1, and the industrial control computer is equipped with a PMAC card to control the stepping motor. The PMAC card is installed in the industrial control computer, the outside is connected with the interface board, and the interface board is connected with the servo motor through the servo driver. The PMAC card is connected with various sensors through the input and output interface board, and the control program is compiled in the computer. The control program calls the corresponding PMAC card motion control program to complete the drive of the servo motor and walk out of the corresponding trajectory. Combined with the specific situation of this test bench, the 12-axis PMAC control card combined with the servo interface board and the input and output interface board is used for system control. The hardware structure is as follows: Figure 31 As shown, other content adapts to change.

Abstract

The invention discloses a control system for a machine tool rolling functional component precision retaining ability measurement device. An industrial control computer is arranged on a force application component servo motor (701), and an eight-axis PMAC card is installed inside the industrial control computer. The control system is used for accomplishing machining path input, setting of tool parameters and cutting parameters, total cutting force calculation, total cutting force time curve drawing, total torque calculation and total torque time curve drawing; cutting component force in the X-axis direction, cutting component force in the Y-axis direction and cutting component force in the Z-axis direction are calculated, a time curve of the cutting component force is drawn, the cutting component force in the X-axis direction, the cutting component force in the Y-axis direction, the cutting component force in the Z-axis direction and the total toque are combined to be decomposed to all servo shafts, the component force time curve of each servo shaft is calculated, and the time curve is divided by the spring coefficient K on a force application mechanism to obtain the time displacement curve of each servo shaft. During operation of a control program, the displacement value of each servo shaft is output to a control PMAC axis control card through a lock widget, the PMAC card calls a corresponding motion control program, the servo motor is controlled to move to the corresponding displacement point, and needed force is applied.

Description

technical field [0001] The invention relates to the technical field of mechanical structure design and application, and in particular provides a control system for a measuring device for accuracy retention of rolling functional parts of a machine tool. Background technique [0002] In the prior art, the measurement of the accuracy retention of machine tool screw and guide rail is usually carried out on the actual machine tool in machining practice, which has many technical problems to be solved urgently.
