Abstract
The utility model discloses an easily clamped hob which comprises a cutter shaft and cutting teeth. The cutting teeth are arranged along the circumference of the cutter shaft, a through hole is formed in the middle of the cutter shaft, and a key groove is formed in the through hole which is a taper hole. Due to the fact that the through hole in the cutter shaft is a taper hole, when passing through the through hole, a core rod can be easily clamped, dismantling and installing are both very convenient, and processing efficiency can be greatly improved.
Description
Technical field
The invention belongs to the Gear Processing field, be specifically related to a kind of gear hob.
Background technology
Hobboing cutter is the cutter of the machining gears commonly used.Add man-hour, hobboing cutter is equivalent to a helical gear that helical angle is very large, its number of teeth is a number of hobboing cutter, workpiece is equivalent to another helical gear, each other according to a pair of helical tooth crop rotation space engagement, with fixing speed ratio rotation, become tooth-formation of gear by the cutter tooth profile of tooth envelope of each adjacent position of cutting successively.Hobboing cutter commonly used is single head (seeing screw thread) mostly, in a large amount of production, also often adopts multiple thread hob in order to improve precision and fineness.Be provided with through hole in the cutter shaft of existing hobboing cutter, general through hole is circular hole, and when with plug, hobboing cutter being fixed, it is not too convenient to mount and dismount, thereby causes the clamping difficulty.
Therefore, need a kind of new hobboing cutter to address the above problem.
Summary of the invention
Goal of the invention: the present invention is directed to the defective that hobboing cutter in prior art is difficult for clamping, a kind of easy clamping hobboing cutter is provided.
Technical scheme: for solving the problems of the technologies described above, easy clamping hobboing cutter of the present invention adopts following technical scheme:
A kind of easy clamping hobboing cutter comprises cutter shaft and cutting teeth, and described cutting teeth is along the circumferential setting of described cutter shaft, and the middle part of described cutter shaft is provided with through hole, is provided with keyway in described through hole, and described through hole is bellmouth.
Beneficial effect: the cutter shaft inner via hole of easy clamping hobboing cutter of the present invention is bellmouth, and when passing through hole with plug, easily clamping, and dismounting and install all very conveniently can improve working (machining) efficiency greatly.
