Abstract
The utility model relates to the technical field of machining equipment, in particular to a taper ball-end cutter, which comprises a cutter handle part and a cutter edge part formed on one side of the cutter handle part, wherein the cutter edge part comprises a plurality of sharp cutter parts, a cutting surface is formed between the sharp cutter parts, the cutting surface and the sharp cutter parts rotate around the same central shaft, a cutting part is formed on the top of the cutter edge part, and the diameter of the cutting part is smaller than that of the cutter edge part; the diameter that is equipped with the cutting portion is less than the diameter of cutting edge portion, can make the top of tapering bulb sword more sharp-pointed, when using the tapering bulb sword, aims at the cutting portion earlier and uses, just can make the cutting dynamics increase of tapering bulb sword to the practicality of increase tapering bulb sword still makes the drilling circularity more accurate through the cooperation of sharp cutting portion and cutting face.
Description
Technical Field
The utility model relates to a machining equipment technical field specifically is a tapering bulb sword.
Background
The ball-end cutter is a cutter with a sharp cutter part similar to a ball head and assembled on a milling machine for milling various curved surfaces and arc grooves; the practical requirement to article is higher and higher in the present stage, and the requirement to machining precision is also higher and higher in the machine-building trade, and the drill bit is as a machining cutter commonly used, and its structure not only is deciding intensity, life of self, more is deciding the error size and the precision height of drilling out the work piece hole, because the bulb sword can normally be worked under high temperature environment, so the usage of bulb sword is very wide, but current bulb sword cutting strength is less, and the practicality is lower.
SUMMERY OF THE UTILITY MODEL
The utility model provides a taper ball-end cutter for overcoming the defects, which adopts the following technical scheme.
The taper ball-end cutter comprises a cutter handle part and a cutter edge part formed on one side of the cutter handle part, wherein the cutter edge part comprises a plurality of sharp cutter parts, a cutting surface is formed between the sharp cutter parts, the cutting surface and the sharp cutter parts rotate around the same central shaft, a cutting part is formed at the top of the cutter edge part, and the diameter of the cutting part is smaller than that of the cutter edge part.
Further, the thickness of the cutting part ranges from 1mm to 3 mm.
Optionally, a spiral part is further formed at one end of the sharp knife part close to the knife handle part, and the spiral part is in a twist shape.
Furthermore, a chip groove is formed on one side of the cutting surface.
Further, the diameter of the shank portion is larger than the diameter of the blade portion.
Optionally, the end of the tool shank is provided with a chamfer.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the diameter that is equipped with the cutting portion is less than the diameter of cutting edge portion, can make the top of tapering bulb sword more sharp-pointed, when using the tapering bulb sword, aims at the cutting portion earlier and uses, just can make the cutting dynamics increase of tapering bulb sword to the practicality of increase tapering bulb sword still makes the drilling circularity more accurate through the cooperation of sharp cutting portion and cutting face.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of a label a.
The reference numerals are respectively: a shank part 1, a blade part 2, a sharp blade part 3, a cutting surface 4, a cutting part 5, a spiral part 6, a chip groove 7 and a chamfer 8.
Detailed Description
The utility model provides a tapering bulb sword, includes handle of a knife portion 1 and the cutting edge portion 2 of shaping in handle of a knife portion 1 one side, cutting edge portion 2 includes a plurality of sharp sword portions 3, and the shaping has cutting face 4 between the sharp sword portion 3, and cutting face 4 and sharp sword portion 3 are rotatory around same center pin, and the shaping of cutting edge portion 2 top has cutting portion 5, and the diameter of cutting portion 5 is less than the diameter of cutting edge portion 2.
Further, the cutting part 5 with an acute angle is arranged, so that the top of the taper ball-end cutter is sharper, when the taper ball-end cutter is used, the cutting part 5 is firstly aligned for use, so that the cutting strength of the taper ball-end cutter is increased, the practicability of the taper ball-end cutter is increased, and the roundness of a drilled hole is more accurate through the matching of the taper part 3 and the cutting surface 4.
Further, the thickness range of the cutting part 5 is 1mm-3 mm; the cutting portion 5 can be prevented from being easily broken.
Optionally, a spiral part 6 is further formed at one end of the sharp cutter part 3 close to the cutter handle part 1, and the spiral part 6 is in a twist shape; the spiral part 6 is arranged, so that the taper ball-end cutter can be in different shapes when in use, and the practicability is enhanced.
Furthermore, a chip groove 7 is formed on one side of the cutting surface 4; the chip grooves 7 are arranged to facilitate the discharge of chips generated during use.
Further, the diameter of the tool shank part 1 is larger than that of the tool edge part 2; the diameter of the tool shank part 1 is larger than that of the tool edge part 2, so that the taper ball-end cutter can be conveniently installed.
Optionally, a chamfer 8 is arranged at the tail end of the tool shank part 1; the chamfer 8 is arranged, so that the taper ball-head cutter can be conveniently installed in the electric drill, and the handle part 1 of the cutter is prevented from being scratched by the electric drill.
Various other modifications and alterations of the disclosed structure and principles may occur to those skilled in the art, and all such modifications and alterations are intended to be included within the scope of the present invention.
