Abstract

The invention relates to a derusting machine for railway wagon wheelsets and a derusting device for an axle body. The shaft derusting device includes: an axial movement mechanism installed on the installation frame; a radial feed mechanism arranged on the axial movement mechanism; a brush shaft mechanism including a drive assembly, a brush shaft assembly, a buffer elastic member and A wire brush, the wire brush is arranged on the brush shaft assembly, and the buffer elastic member is arranged on the brush shaft assembly and abuts against the wire brush. During rust removal, the radial feed mechanism drives the brush shaft assembly to make the wire brush contact the shaft body of the wheel set, and the axial movement mechanism drives the radial feed mechanism and the brush shaft assembly to move to realize the derusting of the shaft body; at the same time, the buffer The elastic part provides elastic pre-tightening force, which makes the wire brush close to the root of the wheel set, keeps the wire brush close to the root, ensures that the root of the wheel set can fully contact with the wire brush, and ensures the cleaning effect.

Description

technical field [0001] The invention relates to the technical field of derusting equipment, in particular to a derusting machine for railway freight wheel sets and an axle body derusting device. Background technique [0002] During the maintenance of railway freight wheel sets, external cleaning, paint, and rust removal must be carried out on the wheel set shaft body and the dust-proof plate seat where the bearings have been removed, so as to meet the flaw detection requirements. For the junction of the wheel hub and the axle body after press-fitting, it is necessary to remove rust from the root to ensure the rust removal effect of the wheel set. [0003] The current steel wire brush and the drive shaft adopt a rigid direct connection method, relying on the cylinder to push the steel wire brush close to the joint between the hub and the shaft body, and there is an assembly error between the wheel and the wheel shaft. The stroke is constant, and the wheel set with a wide whe...
