Grinding wheel for automatically grinding diamonds

Abstract

The invention provides a grinding wheel for automatically grinding diamonds, which comprises a wheel body and a tool bit which is fixedly arranged on the wheel body, and is characterized in that: a bolt is fixedly connected to the back surface of the tool bit; a threaded hole is correspondingly formed on the wheel body corresponding to the tool bit; and the tool bit is detachably fixed on the wheel body through the bolt and the threaded hole. The tool bit is detachably locked on the wheel body through the bolt and the threaded hole, the tool bit is firmly connected with the wheel body, a phenomenon that the tool bit unexpectedly drops can be prevented in the grinding process, the potential safety hazards are eliminated, and the working safety of the grinding wheel is ensured; moreover, after a tool bit layer is ground, a novel tool bit is relocked on the wheel body after a residual tool bit is screwed out, the conventional complex welding process is saved, the time for a machining operator to replace a grinding tool is greatly saved, the assembly and disassembly are simple and convenient, lots of manpower and material resources are saved, the wheel body can be recycled, the resources are saved, the product cost is reduced, and the grinding wheel has good social benefit and economic benefit.

Description

technical field [0001] The invention relates to an automatic abrasive tool, in particular to an automatic diamond grinding disc. Background technique [0002] Diamond Grinding Disc: Refers to the disc-type abrasive tools used on hand grinders and automatic grinders, consisting of a disc body and a diamond grinding block. The diamond is welded or inlaid on the disc body, and the working surface is smoothed and polished by the high-speed rotation of the mill. and polished. [0003] The existing diamond grinding discs for automatic grinding machines include 12-section cutter heads (the cutter head is generally length*width*height) that are installed on the cast iron disc body and equidistantly welded on the cast iron disc body through locking pieces. 40mm*10mm*8mm cuboid block), this traditional diamond grinding disc mainly has the following disadvantages: 1.

Problems solved by technology

[0003] The existing diamond grinding discs for automatic grinding machines include 12-section cutter heads (the cutter head is generally length*width*height) that are installed on the cast iron disc body and equidistantly welded on the cast iron disc body through locking pieces. 40mm*10mm*8mm cuboid block), this traditional diamond grinding disc mainly has the following disadvantages: 1. The cutter head is fixed on the disc body by welding, the welding process is cumbersome, time-consuming and labor-intensive, low production efficiency and high cost , and the diamond grinding disc during grinding is under load, and the grinding machinery itself vibrates during the processing process, which causes the cutter head welded on the disc body to fall off easily, and there are unsafe factors; 2. The diamond material layer of the cutter head After grinding, the disc body will also be discarded at the same time, which cannot be reused, resulting in waste of resources and increasing product processing costs; 3. The cutter head is only arranged on the outer circumference of the disc body, that is, only one circle is arranged at equal intervals on the disc body The cutter head, the uniform division of the cutter head on the disc body is insufficient, and the cutter head is a cuboid shape, the difficulty of drainage of the cutter head reduces the sharpness, resulting in poor overall stability of the disc body during the grinding process and large grinding resistance. It will lead to the end jump of the disc body, it is difficult to control the grinding uniformity, the excellent rate of processing is low, the noise generated during the grinding process is large, the working environment is harsh, and it is not environmentally friendly. When processing ultra-thin stone plates, it is easy to cause stone damage, and the grinding work is stable. Poor performance and low work efficiency; 4. Grinding cast iron grinding discs is easy to cause cracks, and there are also potential safety hazards
