Abstract

The invention discloses a longitudinal magnetization moving coil device for plain shaft and crank shaft magnetic particle inspection. The longitudinal magnetization moving coil device comprises a plurality of longitudinal magnetization coils, a moving mechanism and a guide rail, wherein each longitudinal magnetization coil has a round integral structure; the guide rail is positioned on the front side of the longitudinal magnetization coils; the moving mechanism comprises a motor, a support, two guide rods, a screw rod, a connecting rod, coil connecting frames and a coil moving frame; the support is positioned on the back side of the longitudinal magnetization coils; the motor is connected with the left end of the screw rod through a driving device; an upper shaft sleeve and a lower shaft sleeve are arranged on the coil connecting frames, and are respectively sleeved on the two guide rods which are positioned on the support; the quantity of the coil connecting frames is the same as that of the longitudinal magnetization coils; a coil trough is formed on each coil connecting frame; the back sides of the longitudinal magnetization coils are buckled in the troughs of the back sides; coil troughs and a guide wheel are arranged on the coil moving frame; the front sides of the longitudinal magnetization coils are buckled in the coil troughs; and the guide wheel of the coil moving frame is positioned on the guide rail.

Description

technical field [0001] The invention relates to a magnetic particle flaw detection machine, in particular to a longitudinal magnetization moving coil device for optical axis and crankshaft magnetic particle flaw detection in the magnetic particle flaw detection machine. Background technique [0002] An existing flaw detection machine that can be used for magnetic particle flaw detection of optical shafts and crankshafts contains several longitudinal magnetized coils, and the longitudinal magnetized coils are horizontally arranged in a row. The longitudinal magnetizing coil usually adopts the structure form of two semicircular split split coils. Due to the split-type opening and closing coil structure, when the opening and closing coil is closed and energized, it is easy to catch fire at the closed place, which often leads to fire and safety accidents. In addition, because the opening and closing coils are easy to catch fire at the closed position, the contact parts of the o...
