Dust guard seat rust removal device and method

Abstract

The invention relates to a dust guard seat rust removal device and method. The device comprises a first servo motor, a first transmission shaft, a first support, a side brush, a first moving mechanism, a controller and a detector. The side brush is arranged on the first transmission shaft. The detector is used for detecting a working current of the first servo motor, and the controller is used for controlling the first moving mechanism to move and work according to the current detection value of the detector. When rust removal work is carried out, the first support is moved through the first moving mechanism, so that the side brush can get close to a dust guard seat to make contact with the dust guard seat, the side brush is pressed on the dust guard seat with a constant pressure, the first servo motor drives the first transmission shaft to rotate to drive the side brush to rotate, and rust removal treatment can be carried out on the dust guard seat when the side brush rotates. Therefore, on the one hand, the environmental pollution can be reduced as a paint remover is not adopted. On the other hand, the side brush is pressed on the dust guard seat at constant pressure and conducts rotary rust removal, so that the rust removal effect is good, and meanwhile the rust removal and paint removal efficiency is high.

Description

technical field [0001] The invention relates to the technical field of derusting wheel sets, in particular to a derusting device and method for a dust-proof board base. Background technique [0002] During the forging and repairing of railway vehicles, it is necessary to perform surface magnetic particle inspection on the wheelsets of railway vehicles. see figure 1 , figure 1 A schematic structural view of a wheel set of an embodiment is shown. The wheel set 10 includes a wheel axle 11 and two wheels 12 fixed on the wheel axle 11 . According to the flaw detection requirements, all the flaw detection parts on the wheel set 10 must expose the basic metal surface. The flaw detection parts on the wheel set 10 include the shaft body 111 , the dustproof plate seat 112 , the shaft body insertion section 113 and the web plate hole 121 . Axle body 111 is the position corresponding to between two wheels 12 on the wheel axle 11, corresponding to figure 1 The S1 section in the mid...

Problems solved by technology

[0003] However, on the one hand, for the cleaning and derusting process of the segment repair wheel shaft, because most of the surface of the dustproof plate base 112 is well adhered to the antirust varnish, it is necessary to apply a paint remover on the surface of the dustproof plate base 112 before cleaning and derusting. Cleaning operations, cleaning and rust removal operations are actually paint removal operations

The paint remover has strong corrosiveness, high volatility, high toxicity, and serious environmental pollution. Especially in winter when the doors and windows are closed, the sour smell in the forging warehouse is very strong, which may cause adverse effects on the health of employees.

On the other hand, in the swing arm type feeding mechanism, there will always be intermittent jumping of the wire brush on the dustproof plate seat 112, and the rust removal effect and efficiency are relatively poor.
