Description

Technical Field

[0001] The utility model relates to the field of dressing equipment for grinding and polishing brushes, in particular to an automatic centering tool for clamping grinding and polishing brushes. Background Art

[0002] With the continuous improvement of the processing technology level of copper alloy strips, users' requirements for the surface quality of copper alloy strips are also constantly increasing. Grinding and polishing are important stations for improving the surface quality of copper alloy strips in the cleaning process. Grinding and polishing brushes are usually used to treat the surface of copper alloy strips to obtain high-quality copper alloy strips. However, it is found during use that due to the different surface flatness of different copper alloy strip workpieces, when a grinding and polishing brush polishes the surface of a copper alloy strip in one shift, and then polishes the surface of another shift of copper alloy strips, it will cause the surface of the copper alloy strips polished later to have horizontal vibration lines and other texture defects. Therefore, each time the surface of a shift of copper alloy strips is processed, a new grinding and polishing brush needs to be continuously replaced. If the replaced grinding and polishing brush is directly discarded, it will cause serious waste of resources. Therefore, it is urgent to develop a device that can help trim the bristle circularity of the grinding and polishing brush. Utility Model Content

[0023] Example

[0024] In the specific implementation of the utility model, the grinding and polishing brush comprises a cylindrical grinding and polishing brush bakelite core brush barrel 1-1 and a brush 1-2 arranged on the outer surface of the grinding and polishing brush bakelite core brush barrel 1-1 and distributed in a cylindrical shape. After a shift of surface grinding and polishing of a copper alloy strip, the lengths of the brush 1-2 are uneven, which affects the surface treatment of the copper alloy strip in the next shift and needs to be trimmed. Figure 1 As shown, first, one end of the central shaft 1 is sleeved with a conical flange 2, and the mounting hole 203 on the end cover plate 201 is matched with the matching shaft section 103 of the central shaft 1 to improve the concentricity of the conical sleeve 202 and the central shaft 1, and then the sleeved conical flange 2 is tightened by using the spring washer 4, the flat washer 5 and the nut 3, and the grinding and polishing brush bakelite core brush cylinder 1-1 is sleeved on the central shaft from the other end of the central shaft 1, and another conical flange 2 is sleeved, and the grinding and polishing brush bakelite core brush cylinder 1-1 is placed between the two end cover plates 201, and the two conical sleeves 202 clamp the grinding and polishing brush bakelite core brush cylinder 1-1, and the polishing brush is polished. The light brush bakelite core brush barrel 1-1 is coaxially arranged with the tapered sleeve 202, and then the second tapered flange 2 is locked by using the spring washer 4, the flat washer 5 and the nut 3 to complete the clamping of the grinding and polishing brush. It should be noted that the length of the grinding and polishing brush bakelite core brush barrel 1-1 is less than the distance between the two installed end cover plates 201 and the length is greater than the distance between the two tapered sleeves 202. The inner diameter of the grinding and polishing brush bakelite core brush barrel 1-1 is between the maximum outer diameter and the minimum outer diameter of the tapered sleeve 202, which can effectively ensure that the two tapered sleeves 202 clamp the grinding and polishing brush bakelite core brush barrel 1-1 in the middle position;

[0025] After that, the assembled whole equipment is hoisted onto the grinding machine, and the grinding machine top is used to support the top center hole 6 at both ends of the center axis 1, and the bristles of the grinding and polishing brush are ground. The circumferential length of the bristles of the grinding and polishing brush after grinding can be effectively guaranteed. When it is used to grind and polish the copper alloy strip, the surface of the copper alloy strip will not have vibration marks due to the uneven length of the bristles of the grinding and polishing brush.

[0026] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
