[0005] The following are further improvements to the above technical solution: 1. In the above scheme, each of the brackets has two guide columns, which are located on the upper and lower sides of the piston rod of the cylinder, respectively.

[0006] 2. In the above scheme, the pressure plate further includes a push plate and a contour plate located on the push plate facing the surface of the core column.

[0007] 3. In the above scheme, the number of pressure plates is 3, and the number of cylinders is 3.

[0008] 4. In the above scheme, the roller brush body has a hard bristle mounting area spirally arranged along the axial direction on its side surface.

[0009] 5. In the above scheme, the contoured surface of the pressure plate is provided with a recessed area for the hard bristle installation area to be embedded in a spiral arrangement along the axial direction.

[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model relates to a roller brush clamping fixture, comprising: a base plate and a core column disposed on the base plate for the roller brush body to be fitted into. Several pressure plates are evenly spaced around the core column.

Detailed Implementation

[0013] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0014] Example 1: A roller brush clamping fixture, the roller brush including a roller brush body 100 and a plurality of soft bristles 101 spaced apart on the side surface of the roller brush body 100, including: a base plate 1 and a core column 4 disposed on the base plate 1 and fitted into the roller brush body 100, a plurality of pressure plates 2 are equally spaced around the core column 4, the surface of the pressure plate 2 facing the core column 4 is a contoured surface 3 corresponding to the side surface of the roller brush body 100, a bracket 5 is disposed on the side of the pressure plate 2 opposite to the core column 4, a cylinder 6 connected to the pressure plate 2 is mounted on the bracket 5, a guide post 7 is horizontally disposed between the bracket 5 and the pressure plate 2, and the bracket 5 has a guide hole 8 for the guide post 7 to be inserted.

[0015] The aforementioned pressure plate 2 further includes a push plate 21 and a contour plate 22 located on the surface of the push plate 21 facing the core column 4.

[0016] The aforementioned roller brush body 100 has a hard bristle mounting area 102 spirally arranged along the axial direction on its side surface.

[0017] The contoured surface 3 of the pressure plate 2 is provided with a recessed area 9 for the hard bristle mounting area 102 to be inserted into in a spiral manner along the axial direction.

[0018] Example 2: A roller brush clamping fixture, the roller brush including a roller brush body 100 and a plurality of soft bristles 101 spaced apart on the side surface of the roller brush body 100, including: a base plate 1 and a core column 4 disposed on the base plate 1 and fitted into the roller brush body 100, a plurality of pressure plates 2 are equally spaced around the core column 4, the surface of the pressure plate 2 facing the core column 4 is a contoured surface 3 corresponding to the side surface of the roller brush body 100, a bracket 5 is disposed on the side of the pressure plate 2 opposite to the core column 4, a cylinder 6 connected to the pressure plate 2 is mounted on the bracket 5, a guide post 7 is horizontally disposed between the bracket 5 and the pressure plate 2, and the bracket 5 has a guide hole 8 for the guide post 7 to be inserted.
