Magnetic particle flaw detector being compatible with several types of torsion bars

Abstract

The invention discloses a magnetic particle flaw detector being compatible with several types of torsion bars. The magnetic particle flaw detector comprise a working table board; a first side plate isinstalled at the top of the working table board; a second side plate is connected to one side, corresponding to the first side plate, of the top of the working table board; a control switch is installed in the top of the second side plate in an embedded manner; and a magnetic powder liquid storage bin is connected to one end of the first side plate. According to the invention, the magnetic particle flaw detector based on the scientific and reasonable structure is used safely and conveniently. With a fixed base, a clamping spring, and clamping base plates, different clamping base plates can bedriven to move inwardly based on torsion bars with different diameters, so that the torsion bars with different diameters are installed and thus can be clamped and fixed conveniently. With the magnetic powder liquid storage bin, a crank, and stirring blades, the crank can be rotated and magnetic powder liquid received in the magnetic powder liquid storage bin can be stirred, so that the precipitation caused by the magnetic powder liquid can be reduced, the precipitation of the magnetic powder in the magnetic powder liquid can be prevented, and thus the flaw detection of the torsion bars can be protected.

Description

technical field [0001] The invention relates to the technical field of magnetic particle flaw detection, in particular to a magnetic particle flaw detection machine that takes into account various types of torsion bars. Background technique [0002] The working principle of the magnetic particle flaw detector is to use the strong magnetic field formed by the opposite current to magnetize the ferromagnetic workpiece. If the workpiece has a crack, a local magnetic field will be formed on both sides of the crack, and the iron powder in the magnetizing fluid can be absorbed by the magnetic field. Features, cracks can be displayed on the surface of the workpiece; [0003] However, when the existing magnetic particle flaw detectors on the market are used, it is impossible to fix various types of torsion bars. The efficiency of rod flaw detection, and when the existing magnetic particle flaw detector is used, when the magnetic powder liquid is stored, the magnetic powder contained...
