Technical Field

[0001] This utility model relates to the field of diamond grinding wheel technology, and more specifically, to a novel diamond grinding wheel. Background Technology

[0002] Diamond grinding wheels are superhard abrasives made with diamond abrasive as the main cutting component and a specific binder. They are mainly used for high-precision grinding, cutting, polishing and other processing of hard and brittle materials. Due to the extremely high hardness of diamond, these grinding wheels can efficiently process materials that are difficult to process with traditional grinding wheels and are widely used in the industrial field.

[0003] A search revealed that Chinese patent CN219426578U discloses a durable diamond grinding wheel. By setting an outer diamond grinding wheel layer outside the inner diamond grinding wheel layer, and the lower part of the outer diamond grinding wheel layer and the lower part of the inner diamond grinding wheel layer can be connected by a screw, the outer diamond grinding wheel layer can be replaced when the outer surface of the outer diamond grinding wheel layer is worn, thus reducing waste.

[0004] When using the aforementioned diamond grinding wheel, after screwing the screw into the external and internal threaded holes, a stable connection can be achieved between the outer diamond grinding wheel layer and the inner diamond grinding wheel layer. However, the stability between the outer and inner diamond grinding wheel layers is poor, and the outer diamond grinding wheel layer is prone to falling off during processing. Utility Model Content

One end of each of the plurality of insert rods is fixedly connected to the two pressure plates, and the other end of each of the plurality of insert rods passes through the two crossbars.

[0008] Furthermore, the opposite sides of the two third gaskets are in contact with the two pressure plates respectively, and the opposite sides of the two third gaskets are in contact with the inner diamond grinding wheel layer.

[0009] As can be seen, in the above technical solution, the third gasket can improve the stability between the pressure plate and the inner diamond grinding wheel layer.

[0010] Furthermore, a connecting assembly is provided on the inner diamond grinding wheel layer. The connecting assembly includes a connecting shaft, a sleeve, multiple fixing bolts, a second washer, and multiple water guide pipes. There are two connecting assemblies. A through hole is opened on the connecting shaft, and multiple water guide holes are opened inside the inner diamond grinding wheel layer.

[0011] Furthermore, one end of the connecting shaft is fixedly connected to the sleeve, and one side of the sleeve is fixed to the inner diamond grinding wheel layer by multiple fixing bolts.

[0012] Furthermore, one side of the second gasket is fixedly connected to the sleeve, and the other side of the second gasket is in contact with the inner diamond grinding wheel layer.

[0013] As can be seen, in the above technical solution, the second gasket can improve the stability between the sleeve and the inner diamond grinding wheel layer.

[0014] Furthermore, one end of each of the multiple water guide pipes is fixedly connected to the connecting shaft, and the outer sides of the multiple water guide pipes are fixedly embedded in the sleeve, and the multiple water guide holes are respectively connected to the multiple water guide pipes.

[0015] It can be seen that the above technical solution is designed to facilitate cooling of the inner diamond grinding wheel layer.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. In this utility model, both crossbars are inserted into the inner diamond grinding wheel layer, thereby initially limiting the two outer diamond grinding wheel layers. At the same time, the two limiting rings can limit the two sides of the two outer diamond grinding wheel layers. The screw is limited and locked by two nuts, so that the inner diamond grinding wheel layer and the two outer diamond grinding wheel layers are fixed together. The operation is simple and effectively improves the stability between the inner diamond grinding wheel layer and the two outer diamond grinding wheel layers.

[0018] 2. This utility model uses a sleeve to protect the fixing component, and four fixing bolts to fix the sleeve to the inner diamond grinding wheel layer, thereby fixing the connecting shaft to the inner diamond grinding wheel layer. External air or water can enter the four water pipes through the through holes, then enter the four water guide holes, and finally exit through another through hole, forming a complete flow channel, which can cool the inner diamond grinding wheel layer. The structure is simple and easy to use. Attached Figure Description
