Barkhausen effect-based numerically controlled machine tool triangular track flaw detection system

Abstract

The invention discloses a Barkhausen effect-based numerically controlled machine tool triangular track flaw detection system, which utilizes a Barkhausen noise signal detection principle to detect a machine tool track on line. Two detection probes which are fixed at the end part of a center rest of a machine tool are utilized to respectively detect two tracks in real time, detection information istransmitted to an external upper computer by the way of wireless communication, and the upper computer can judge whether problems, such as internal cracks, plastic deformation and fatigue damage, exist in the tracks according to the detection information. The whole structure of each detection probe is V-shaped, one side of each detection probe is provided with a magnetizing coil and an iron coreconnected through a spring and wound by a detection coil, an iron core connected through the spring on the other side forms a V-shaped included angle with the iron core wound by the detection coil, the detection probes can clamp the two sides of the to-be-detected triangular tracks of a machine tool under the action of the springs, and therefore the situation that the detection probes are lifted off in a process of detection based on a Barkhausen effect can be overcome.

Description

technical field [0001] The invention relates to a defect detection system for a triangular track of a numerical control machine tool based on the Barkhausen effect. Background technique [0002] A machine tool refers to a machine that manufactures a machine, also known as a machine tool or a tool machine, and is customarily referred to as a machine tool. Generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. The final machining is done by cutting on the machine tool. Machine tools play an important role in the modernization of the national economy. The automatic lathe can automatically complete the multi-process processing of small and medium-sized workpieces according to a certain program, can automatically load and unload materials, and repeatedly p...
