Description

TECHNICAL FIELD

[0001] The utility model relates to diamond grinding wheel field especially relates to a split quick-change diamond grinding wheel. BACKGROUND

[0002] Diamond grinding wheel is usually composed of diamond abrasive layer, transition layer and base, which makes full use of the wear resistance of diamond abrasive. In the grinding process, the diamond abrasive layer has small wear and small size change, which is beneficial to improve the precision of processing.

[0003] Although the diamond abrasive layer has high hardness and is relatively wear-resistant, it will still gradually wear out in the continuous production process. In general, the worn diamond grinding wheel is scrapped as a whole, resulting in serious cost waste. In order to reduce the cost, the utility model discloses a split diamond grinding wheel in the prior art with the application number CN2020224479837, which can clamp and fix the grinding wheel body and replace the grinding wheel body when it is seriously worn. However, the structure is complex, the volume of the grinding wheel body is large, and the cost is high, which needs to be improved. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a split quick-change diamond grinding wheel to improve the convenience of replacement and reduce the cost of replacement.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] A split quick-change diamond grinding wheel comprises a fixed disc, a connecting disc, a positioning sleeve, a positioning pin, a base, a diamond abrasive layer and a transition layer. The fixed disc is provided with a conical shell on the front surface. The conical shell is provided with a fixed ring at the front end. The fixed ring is provided with a ring groove on the inner edge of the front end. The base is arranged in the ring groove. The transition layer is arranged on the outer circle of the base. The diamond abrasive layer is arranged on the outside of the transition layer. A plurality of radial through holes are arranged in the ring groove. The base is provided with a blind hole corresponding to the through hole. The positioning pin is arranged in the through hole and extends into the corresponding blind hole. The positioning sleeve is arranged on the inner side of the fixed ring to block the through hole. The connecting disc is arranged on the front surface of the fixed disc. A plurality of connecting rods are arranged at the rear end of the positioning sleeve and extend to the connecting disc. A plurality of first mounting holes are arranged in the annular array on the fixed disc. A plurality of second mounting holes corresponding to the first mounting holes are arranged on the connecting disc.

[0007] The base adopts a circular ring structure.

[0008] The positioning sleeve, the connecting disc and the connecting rod adopt an integrated structure.

[0009] The fixed disc, the conical shell and the fixed ring adopt an integrated structure.

[0010] The outer diameter of the positioning sleeve corresponds to the inner diameter of the fixing ring.

[0011] The inner diameter of the fixing ring is larger than the outer diameter of the fixing disc.

[0012] The beneficial effects of this utility model are as follows: A split-type quick-change diamond grinding wheel allows the connecting disc and the fixed disc to be fixed to the drive disc with the same screw, making disassembly and assembly convenient. Moreover, the fixing of the connecting disc achieves the fixing of the positioning sleeve, which limits the positioning pin in the through hole. The positioning pin is used to fix the base body, ensuring the working stability of the diamond abrasive layer. After the diamond abrasive layer wears down, the connecting disc can be removed, and the positioning sleeve and positioning pin can be taken out for the base body to be replaced. In addition, the base body is small in size and low in cost, reducing replacement costs. Attached Figure Description
