Description

Brush of deburring equipment

Technical Field

The utility model relates to a brush, in particular to a brush of deburring equipment.

Background

The engine parts need to be deburred on the surfaces and inner holes before leaving the factory so as to remove burrs on the surfaces and prevent the burrs from stabbing operating personnel. When deburring, the deburring device typically deburs it with a brush assembly. The brush assembly comprises a brush body and a rotation driving device for driving the brush body to rotate, and bristles are arranged on the brush body. When the rotary brush is in work, the rotary driving device drives the brush body to rotate, and further burrs on the surface of a workpiece in contact with the brush body are removed. The existing brush body is generally made of a plurality of steel wires which are wound with each other, and the brush hair is clamped between the plurality of steel wires. The bottom end of the steel wire is fixedly arranged on the brush handle, thereby completing the manufacture of the brush body. The brush body manufactured by the method has lower density due to the structural limitation, thereby reducing the burr removing effect.

In view of the above-mentioned drawbacks, the present inventors have made active research and innovation to create a new brush for deburring apparatus, which has a higher industrial utility value.
