Abstract

The invention relates to a machine tool feed shaft coupling looseness prediction and diagnosis device and a diagnosis method thereof, and belongs to the field of machine tool electromechanical integration control. According to the technical scheme, the device comprises a proximity switch and an induction block, wherein the proximity switch is arranged on one side of a coupling of a machine tool feed shaft and connected with an I / O interface of a machine tool numerical control system, and the machine tool feed shaft is driven by a servo motor; the induction block is arranged on the coupling of the machine tool feed shaft and fixedly installed on the outer circle, close to the shaft end of the coupling, of the feed shaft, the proximity switch induces the induction block when the feed shaft rotates, and the switch induces that the induction block is triggered once and sends triggering signal data to the machine tool numerical control system. The numerical control machine tool system carries out processing, comparison and judgment on data obtained by the feed shaft coupling looseness diagnosis device, instant coupler looseness alarm is achieved, machining errors caused by looseness of the coupling are avoided, and the pre-judgment function in the machining process is achieved.

Description

technical field [0001] The invention relates to a machine tool feed shaft coupling looseness prediction and diagnosis device and a diagnosis method thereof, which belong to the field of machine tool electromechanical integration control. Background technique [0002] As we all know, the transmission structure of the feed shaft of the CNC machine tool is that the servo motor assembly drives the ball screw to rotate through the coupling, and the rotation motion of the servo motor is changed into the linear motion of the feed shaft through the nut on the ball screw. The feeding speed is relatively fast, such as the speed of fast forward and fast rewind is usually 10-60m / min, and some even reach above 60m / min. The loosening and twisting of the coupling will be caused, and the loosening and twisting will intensify as the usage time increases. [0003] In actual processing, the main performance is that the movement in all directions is normal, the encoder feedback is also normal,...
