The invention discloses a self-cooling type detachable drill bit device. A cavity is formed in a drill bit. The drill bit comprises a drill bit body at the top, a drill rod in the middle and a connecting portion with the tail pivoted to a drill bit seat. The drill bit body is in an inverted conical shape. The drill rod is in the shape formed by connecting at least two inverted circular truncated cones. The drill bit body and the drill rod are detachably connected. The inverted circular truncated cones of the drill rod are detachably connected. The drill bit seat comprises a pivot joint segment used for being pivoted to the connecting portion of the drill bit. A pivot joint segment body is connected with two tubes extending outwards, namely the grinding aid liquid tube and the cooling gas tube. The drill bit body and the drill rod are detachably designed, and all portions of the drill rod are detachably designed. The drill bit body and the damaged portion on the drill rod can be replaced conveniently, and it is not necessary to replace the whole drill bit when a certain portion of the drill bit is damaged. By the adoption of the detachable design, the length of the drill bit device can be adjusted conveniently according to the site requirements to be suitable for actual machining.
Description
technical field [0001] The invention relates to a drill bit, in particular to a self-cooling detachable drill bit device, which belongs to the technical field of machining. Background technique [0002] Traditional drills are all solid drills. For example, the application number is 201520621081.7, and the name of the invention is a three-edged drill. When used with a drilling machine or a machine tool, it is necessary to add additional coolant and a cooling mechanism to the drilling machine or machine tool, which increases the capacity of the machine tool. Occupying an area, and placing cooling liquid tanks and liquid pipes outside the machine tool increases the burden on operators. [0003] For another example, the application number is 201420811478.8, and the title of the invention is a cemented carbide internal cooling drill. Cooling pipes are arranged inside the drill bit and the drill shank; the hollow cavity of the cooling pipe is filled with an absorption heat transfe...
