Intelligent magnetic powder inspection machine

Abstract

The invention discloses an intelligent magnetic powder inspection machine, and relates to the technical field of magnetic powder inspection. The intelligent magnetic powder inspection machine comprises a detection table, supporting legs, universal wheels, a supporting frame, a connecting piece, a mounting frame, a second rotating shaft, a second motor, a mounting block, a first connecting pipe, a second connecting pipe, a magnetic powder nozzle, a water pipe nozzle, a fixed block and a movable block, wherein the supporting legs are arranged at the bottom of the detection table, the universal wheels are arranged at the bottoms of the supporting legs, the supporting frame is arranged on the detection table, the connecting piece is rotatably arranged on the supporting frame, the mounting frame is arranged at the end, away from the supporting frame, of the connecting piece and is of a U-shaped structure, the second rotating shaft is rotatably arranged on the inner walls of the two longitudinal sides of the mounting frame, and the second motor is arranged on the mounting frame and is in driving connection with the second rotating shaft. According to the intelligent magnetic powder inspection machine, a workpiece can be cleaned before magnetic powder inspection is carried out on the workpiece, so that the influence of impurities such as rust, dust or stains on the inspection result of the workpiece is greatly reduced, and convenience is brought to workers; and meanwhile, the space occupied by the magnetic powder nozzle and the water pipe nozzle is reduced, and use is more flexible.

Description

technical field [0001] The invention relates to the technical field of magnetic particle flaw detection, in particular to an intelligent magnetic particle flaw detection machine. Background technique [0002] At present, the magnetic particle inspection method has been widely used in various fields of industry at home and abroad. The basic principle of magnetic particle inspection is: when ferromagnetic materials are magnetized in a magnetic field, defects or changes in the structure of the surface and near the surface of the material will cause local damage. The magnetic permeability changes, that is, the magnetic resistance increases, so that the magnetic flux in the magnetic circuit is correspondingly distorted: a part of the magnetic flux directly passes through the defect, a part of the magnetic flux bypasses the defect inside the material, and a part of the magnetic flux leaves the surface of the material , the air bypasses the defect and re-enters the material, thus f...

Problems solved by technology

[0003] When the intelligent magnetic particle flaw detection machine in the prior art is used, the workpiece cannot be cleaned before the magnetic particle flaw detection operation on the workpiece. Some workpieces are directly disassembled from the device that has been used for a long time, such as train wheels, etc. There will be A lot of sundries such as rust, dust or stains, these sundries will greatly affect the flaw detection results of the workpiece and bring great trouble to the operators
