Abstract
The utility model relates to the technical field of shaft type workpiece detectors, in particular to a shaft-type workpiece magnetic powder flaw detector. The flaw detector comprises an electrode shaft, a left magnetic yoke coil, a right magnetic yoke coil, support frames and cylinders, wherein the bottoms of the left and the right magnetic yoke coils are respectively connected with one support frame; the support frames are fixed on the cylinders and can freely move along with telescopic piston rods of the cylinder in a longitudinal direction, so that the centre distance of a magnetizing coil can be adjusted, a workpiece can be effectively covered by longitudinal lines of magnetic force, flaw detection of work pieces with different lengths can be executed on the same one detector, and a flaw detection defect caused by intensity weakening of a magnetic field in a mid-point position of the shaft-type work piece is overcome.
Description
Technical field
The utility model relates to shaft-like workpiece checkout equipment technical field, especially a kind of shaft-like workpiece magnetic powder inspection device.
Background technology
Magnetic powder inspection is a kind of nondestructive means of inspection surface defects of ferromagnetic material, is widely used, and axle type defect-detecting equipment is oriented to the product of length-specific more; Or control the flaw detection of different length product through tailstock; Former magnaflux adopts the fixed coil inductive method, if shaft-like workpiece is longer, longitudinal flux line of force distribution center section a little less than; Magnetic field intensity in the intermediate point position is difficult to reach requirement, can cause the defective of detecting a flaw.
The utility model content
Poor for applicability in order to overcome existing magnaflux, detect long workpiece can cause the detecting a flaw deficiency of defective, the utility model provides a kind of shaft-like workpiece magnetic powder inspection device.
The utility model solves the technical scheme that its technical matters adopted: a kind of shaft-like workpiece magnetic powder inspection device; Comprise electrode axis, left yoke coil, right yoke coil and support and cylinder; Left side yoke coil and right yoke coil are enclosed within the two ends of electrode axis respectively; A support is respectively established in the bottom of left side yoke coil and right yoke coil, and support is connected on the cylinder.
According to another embodiment of the utility model, comprise that further left yoke coil and right yoke coil are fixed on the support, support is fixed on the piston rod of cylinder.
The beneficial effect of the utility model is; Support is fixed on the cylinder, can vertically moving arbitrarily, make that longitudinal magnetization hub of a spool distance is adjustable along with stretching of cylinder piston rod; Workpiece is effectively covered by the longitudinal flux line of force; Avoid shaft-like workpiece long, the magnetic field intensity in the intermediate point position is difficult to reach requirement, causes the defective of detecting a flaw.Magnetizing coil in the Workpiece length scope, can be moved freely, realized the flaw detection of different length workpiece on same equipment, eliminated the magnetic field intensity reduction of shaft-like workpiece intermediate point position and the defective that causes detecting a flaw.
