Preferably, in the sanding tool, the hanger plate is welded to the metal frame, the rib plates are welded to two sides of the hanger plate, and the bottom of each rib plate is welded to the metal frame.

Preferably, in the sanding tool, a circular hole is formed in the center of the side plate, so that the sanding tool is suitable for reducing weight.

Preferably, in the sanding tool, the rib plate is triangular.

Preferably, in the sanding tool, the height of the positioning column protruding outside the side plate is 8-15 mm.

Preferably, in the sanding tool, a magnet is adsorbed inside the metal frame.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1-5, a sanding tool comprises a metal frame 2, side plates 1 are welded and fixed to two sides of the metal frame 2, and a circular hole 3 is formed in the center of each side plate 1 and is suitable for reducing weight and saving materials. Two positioning columns 6 are arranged on the side plate 1, and the positioning columns 6 are welded and fixed with the side plate 1. Two positioning columns 6 are positioned at two opposite corners of the side plate 1, so that positioning is facilitated. A hanging plate 5 is fixed on the top of the metal frame body 2, and the hanging plate 5 is vertically fixed on the upper hanging bracket. The hanger plate 5 and the metal frame body 2 are welded and fixed, the rib plates 4 are welded on two sides of the hanger plate 5, the rib plates 4 are triangular, the bottoms of the rib plates 4 are welded and fixed with the metal frame body 2, and the connecting strength of the hanger plate 5 and the metal frame body 2 is enhanced. The positioning column 6 is welded on the side plate 1 before the side plate 1 and the metal frame 2 are welded. In order to ensure that all welding lines are full-length welding with structural strength, the height of the welding leg is not less than 3 mm.

The height of the positioning column 6 protruding outside the side plate 1 is 8-15 mm, so that the threaded hole 8 in the axle box front cover 7 can be conveniently and completely penetrated, and the inconvenience caused by the fact that the positioning column extends out for a long time when the axle box front cover is used is avoided. A magnet is attracted to the inside of the metal frame 2. The main materials of metal framework 2, curb plate 1, axle box protecgulum 7 are iron, and magnet has the adsorption, detains the screw hole 8 of axle box protecgulum 7 on reference column 6 back, and magnet passes through metal framework 2, curb plate 1 firmly adsorbs axle box protecgulum 7, avoids falling down when polishing, and axle box protecgulum 7 does not receive the power of keeping away from metal framework 2 direction when sanding, and the adsorption affinity of consequently magnet is enough to be fixed with axle box protecgulum 7. The side plates 1 at two sides of the metal frame body 2 can be fixed with the axle box front cover 7, and the proper side can be selected according to the requirement to be fixed and sanded. The side edge 9 of the axle box front cover 7 protrudes out of the metal frame body 2, and the side edge 9 can be directly opened outwards by hands after sanding is finished, so that the axle box front cover 7 is convenient to take down.

When the sanding tool is used for sanding the axle box front cover 7, the threaded hole 8 of the axle box front cover 7 is buckled on the positioning column 6, the magnet firmly adsorbs the axle box front cover 7 through the metal frame body 2 and the side plate 1, the phenomenon that the axle box front cover 7 falls down when sanding is avoided, the axle box front cover 7 is not forced to be away from the metal frame body 2 when sanding, and therefore the adsorption force of the magnet is enough to fix the axle box front cover 7. After sanding, the side edges 9 can be directly and outwardly broken by hands, and the axle box front cover 7 can be conveniently taken down. The sanding tool is convenient for fixing the axle box front cover and taking down the axle box front cover after sanding.
