Description

Technical Field

[0001] The utility model relates to the technical field of diamond tool, in particular to a diamond tool with a chip breaker groove. Background Art

[0002] Diamond tools have the advantages of extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals. They can be used for precision machining of non-metallic hard and brittle materials such as graphite, highly wear-resistant materials, composite materials, high-silicon aluminum alloys and other tough non-ferrous metal materials. During machining, iron chips sometimes continue to flow, which is not good for machining and tools. Therefore, diamond tools are often equipped with chip breaking grooves to break the iron chips.

[0003] At present, most of the existing diamond tool bars with chip breaker grooves are integrated structures. When the tool bar is fixed to the tool holder, the tool bar is generally fixed to the tool holder by multiple bolts on the tool holder. However, as the tool is continuously disassembled and assembled, the tool bar is greatly damaged by the fixing of the bolts, which easily causes surface problems such as wear and depression on the fixing surface of the guide rod, making the fixing stability of the tool bar worse when it is fixed by bolts again. At this time, if the tool bar is replaced to ensure the fixing stability, it will cause a large cost waste. Therefore, the utility model proposes a diamond tool with a chip breaker groove to solve the shortcomings of the existing technology. Utility Model Content

[0020] The connection method between the cutter head body 2 and the cutter head groove 3 of the utility model is the prior art. When the diamond tool with a chip breaker groove of the utility model is used and fixed, when one fixed surface of the movable tool rod part 101 is constantly disassembled and assembled with the tool holder and is worn by the bolts on the tool holder, in order to avoid the surface depression caused by wear affecting the stability when clamping again, the movable tool rod part 101 can be rotated to make the other fixed surface on the movable tool rod part 101 rotate to the current position and be assembled with the tool holder. During operation, first use the limit drive mechanism 7 to drive the limit mechanism 6 to disengage from the connection with the fixing hole 104, then rotate the movable tool rod part 101 rotatably installed with the rotating groove 103 on the fixed tool rod part 102 by ninety degrees, and then use the limit drive mechanism 7 again to drive the connection between the limit mechanism 6 and the fixing hole 104, so as to realize the connection between the movable tool rod part 101 and the fixed tool rod part 102 into a whole, and then assemble and fix the movable tool rod part 101 with the tool holder.
