Title:
MACHINE TOOL ELECTRICAL CONNECTION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/215265
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a machine tool electrical connection structure with which the disturbance of a transmission signal on which a power source is superimposed and the occurrence of sparks in a power source line can be prevented when exchanging a working member for performing a target operation on a machining target, in a machine tool such as a machining robot or an NC processing machine. Provided is a machine tool electrical connection structure, in which an inrush current relaxation resistor is inserted into a power source line and a signal line for transmitting a transmission signal on which the power source is superimposed, and a bypass route is provided in parallel with the inrush current relaxation resistor. The bypass route is put in a conduction disabled state before attachment of the working member for performing a target operation on a machining target, and the bypass route is put in a conduction enabled state at a predetermined timing after the attachment of the working member.
