Title: Deburring brush

Description:
TECHNICAL FIELD 
     The present invention relates to a surface treatment device, more particularly to a metal surface treatment device. 
     BACKGROUND ART 
     During manufacturing process of aluminum alloy wheels, deburring cost accounts for a very large part of the overall cost due to huge consumption of deburring brushes. More and more enterprises have begun exploring and developing a variety of novel deburring brushes to reduce the deburring cost. A deburring brush with replaceable bristles is a future development trend of wheel deburring brushes due to its flexibility, its chassis part being reusable, thus greatly reducing the cost. However, how to make it convenient to disassemble the shortened bristles while reducing the cost is a new technical problem we are faced with. 
     INVENTION CONTENTS 
     An object of the present invention is providing a wheel deburring brush with conveniently replaceable bristles. 
     To achieve the above object, the present invention adopts the following technical solution: a deburring brush comprises a pressing plate, jacking posts, copper sleeves, gaskets, guide posts, springs, a bottom plate, magnets, a top plate and bristle units. The magnet is fixed between the bottom plate and the top plate, and the magnets grip the bristle units, thus forming a body of the deburring brush. 
     The guide posts are fixed below the bottom plate, and the copper sleeves cooperating with the guide posts are embedded on the pressing plate; the pressing plate, above which are mounted the jacking posts, is fixed between the springs and the gaskets at the ends of the guide posts; and the top ends of the jacking posts pass through holes of the bottom plate and the magnets, and are in contact with the bottoms of the bristle units. 
     When the bristle units need replacement, it only needs to place the deburring brush on the ground and then press down edges of the front side of the top plate, so that all the bristle units will fall off against the suction force of the strong magnets under the action of each jacking post. 
     According to the present invention, it avoids being time consuming and labor intensive due to removing the bristle units one by one by using a screw driver or other similar devices while replacing the bristle units, and at the same time the replacing speed of bristles is greatly increased.

     DETAILED DESCRIPTION 
     Details and operation of the specific device provided by the present invention will be described below in conjunction with the accompanying drawings. 
     The deburring brush comprises a pressing plate  1 , jacking posts  2 , copper sleeves  3 , gaskets  4 , guide posts  5 , springs  6 , a bottom plate  7 , magnets  8 , a top plate  9  and bristle units  10 . The magnets  8  are fixed between the bottom plate  7  and the top plate  9 , and the magnets  8  grip the bristle units  10 , thus forming a body of the deburring brush. 
     The guide posts  5  are fixed below the bottom plate  7 , and the copper sleeves  3  cooperating with the guide posts  5  are embedded on the pressing plate  1 ; the pressing plate  1 , above which are mounted the jacking posts  2 , is fixed between the springs  6  and the gaskets  4  at the ends of the guide posts  5 ; and the top ends of the jacking posts  2  pass through holes of the bottom plate  7  and the magnets  8 , and are in contact with the bottoms of the bristle units  10 . 
     During operation, when the bristle units  10  need replacement, it only needs to place the deburring brush on the ground and then press down edges of the front side of the top plate  9 , so that all the bristle units  10  will fall off against the suction force of the magnets  8  under the action of each jacking post  2 .
