Summary of the invention
Technical problem to be solved by this invention is to provide a kind of pick, and this pick not only avoid and brings because of operation wearing and tearing loaded down with trivial details process of changing, and saves material, improves operating efficiency.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of pick, it comprises denticle and alloy cutter head, described alloy cutter head is embedded in denticle front end, it is characterized in that: described alloy cutter head comprises the cylinder of mid portion and the cone point of a knife at two ends, described denticle hub head end be processed with described alloy cutter head mid portion cylinder and one end cone point of a knife with the use of inner chamber, rear end, described denticle axle center is processed with pilot hole.
As preferred embodiment, the cone point of a knife at described alloy cutter head two ends scribbles dlc protective layer.
As preferred embodiment, the cylinder of described alloy cutter head mid portion and the cone point of a knife at two ends are that integral type is arranged.
As preferred embodiment, on the cylinder of described alloy cutter head mid portion, processing is in helicitic texture.
As preferred embodiment, the inner chamber of described denticle hub head end comprises cylindrical cavity and cone inner chamber two parts, and be processed with on the inwall of described cylindrical cavity with helicitic texture on described alloy cutter head cylinder with the use of threaded portion.
As preferred embodiment, described denticle is assembled by central axis and toothholder, and described central axis one end is fixed in the pilot hole of rear end, described denticle axle center by two elastic spring, and the described central axis other end is fixed by circlip and described toothholder.
As preferred embodiment, between described denticle and described toothholder, be provided with wear-resisting ring.
As preferred embodiment, between described denticle and described central axis, be provided with shock absorbing ring and sealing ring.
Beneficial effect of the present invention: the design of the point of a knife structure at (1) alloy cutter head two ends, fundamentally solve the process that replacing that pick alloy cutter head in operation process brings because wearing and tearing severity is loaded down with trivial details, save the activity duration, save material, and easy to process; (2) timely along with alloy cutter head two ends point of a knife conversion process, make the point of a knife of alloy cutter head and denticle and toothholder wearing and tearing all with, more effectively prevent denticle and toothholder rapid wear, be delayed the application life of pick; (3) setting of dlc protective layer enhances abrasion resistance and the intensity of alloy cutter head, improves operating efficiency, extends the application life of alloy cutter head and pick; (4) interpolation of shock absorbing ring between denticle and central axis, reduces the vibrations produced in pick operation process, thus improves the operating efficiency of pick, effectively protects alloy cutter head, denticle and toothholder.
