Abstract

The invention relates to a device, particularly to a workpiece magnetic powder inspection device with a hole in the middle and a complicated shape. The workpiece magnetic powder inspection device is characterized in that after being connected with a left air cylinder and a left movable coil, a left silicon steel sheet electrode shaft penetrates into the left coil of left-right coils; after being connected with a right air cylinder and a right movable coil, a right silicon steel sheet electrode shaft penetrates into the right coil of the left-right coils; up-down coils are arranged above and below the left-right coils; front-back coils are arranged in front of or in the rear of the left-right coils; left-right coil magnetized power supply input terminals are arranged on the left-right coils; up-down coil magnetized power supply input terminals are arranged on the up-down coils; front-back coil magnetized power supply input terminals are arranged on the front-back coils. As the technical scheme is adopted, the workpiece magnetic powder inspection device has the following advantages and benefits: six fixed coils and two movable coils are adopted, so that a rotary magnetic field is formed in the device, cracks on a workpiece can be clearly displayed, and the magnetizing and demagnetizing effects are excellent.

Description

technical field [0001] The invention relates to a device, in particular to a magnetic particle flaw detection device for workpieces with holes in the middle and complex shapes. Background technique [0002] At present, for workpieces with complex shapes and holes in the middle, ordinary magnetic particle flaw detection equipment will be used for flaw detection, which will cause uneven magnetic fields, cracks cannot be clearly displayed, and easily lead to missed inspections. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a magnetic particle flaw detection device with a hole in the middle and a complex shape, which can use six fixed coils and two moving coils up and down, left and right, front and rear, to form a spatial rotating magnetic field inside, and to inspect the workpiece in all directions. Concentrate on workpieces with complex shapes and holes in the middle, and conduct magnetic particle inspection on ...
