The invention discloses an alloy coring drill bit convenient and rapid to disassemble and assemble, and relates to the field of alloy coring drill bits. Aiming at solving the problems that an existingalloy coring drill bit is inconvenient to replace a core, the alloy coring drill bit is inconvenient to fix in an auxiliary mode during work, and the whole drill bit and a drilling machine are inconvenient to fix, the invention provides the following scheme that the alloy coring drill bit convenient and rapid to disassemble and assemble comprises a fixing block, wherein a drill core mounting mechanism is fixedly arranged in the fixing block in a sleeved mode; the top end of the drill core mounting mechanism is fixedly connected with an overall fixing mechanism; the bottom end of the fixing block is fixedly connected with a drill cylinder; the bottom end of the drill cylinder is fixedly connected with a plurality of drill teeth; heat dissipation mechanisms are arranged on the periphery ofthe drill cylinder; and an auxiliary fixing mechanism is fixedly arranged outside the drill cylinder in a sleeving manner. According to the alloy coring drill bit convenient and rapid to disassemble and assemble provided by the invention, core replacement of the alloy coring drill bit is facilitated, auxiliary fixing of the alloy coring drill bit during working is facilitated, fixing of the wholedrill bit and a drilling machine is also convenient, the practicability of the device is improved, and the alloy coring drill bit is suitable for market popularization.
Description
technical field [0001] The invention relates to the field of alloy core drill bits, in particular to an alloy core drill bit which is convenient and quick to assemble and disassemble. Background technique [0002] Coring drills are also called hollow drills, which are mainly tools used to drill holes in steel plates and other products. The hollow drills are matched with a special machine for coring drills, which have the characteristics of high efficiency and low cost. The cutting edge of the core drill is made of hard Made of alloy, with three-layer end-tooth geometry, light cutting, long service life of steel plate drill bit, double-cut flat shank interface, suitable for all kinds of clock drilling rigs. Carbide drill bits are also suitable for various types of vertical drilling machines, radial drilling machines, milling machines, lathes, etc. At present, the alloy core bit is inconvenient to replace the core, and it is also inconvenient to carry out auxiliary fixation d...
