Abstract

The invention provides a threaded hole repairing method and device. The device comprises a demagnetizing magnetic drill and a position adjuster, wherein the position adjuster is arranged on a bogie and can move in the transverse direction and the longitudinal direction on a first plane; the first plane is parallel to the cross section of a threaded hole to be repaired in a tumbler axle box on the bogie; the demagnetizing magnetic drill is fixed on the position adjuster and can move along with movement of the position adjuster; a drill bit of the demagnetizing magnetic drill is positioned above the threaded hole to be repaired; the demagnetizing magnetic drill comprises a power supply access and a magnetizing access; the power supply access is used for providing power for the drill bit of the demagnetizing magnetic drill; the magnetizing access is used for magnetizing a magnet block of the demagnetizing magnetic drill; a demagnetizing switch is arranged in the magnetizing access; and when the threaded hole is repaired, the demagnetizing switch is in a switch-on state. The invention provides the threaded hole repairing method and device, the repairing method is simple, and the cost is relatively low.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a threaded hole repair method and device. Background technique [0002] The bogie is the part with the most accessories on the train, and it is also the most prone to failure. Therefore, the bogie needs to be inspected periodically to ensure the safety of the train. The part with the highest fault frequency on the bogie is the pivot arm axle box, so the pivot arm axle box cover is often removed during the maintenance process to overhaul the pivot arm axle box. Dismantling the pivot box cover for many times will cause the thread teeth in the threaded hole of the pivot box to fall off, which will lead to the failure of the normal installation of the pivot box cover, which will affect the driving safety of the train. [0003] Usually for the repair of the threaded hole of the pivoting arm axle box, it is only completed during the section repair and factory repair of the train. When repairin...
