Abstract
The invention relates to a chamfering tool of a forward inner hole of a taper shank, which belongs to the field of machining. The invention provides a chamfering tool for machining the inner hole, which can solve the inner hole forward chamfering problem of parts which are made of general materials and machine inner hole forward chamfers of all work pieces within the size band of phi 20mm-phi 140mm. The tool consists of the taper shank and a blade, the blade is mounted and fixed in a groove at the lower end of the taper shank, the blade is shaped like a fan with the rectangular lower end, thechamfering tool has simple manufacture and low cost, and the adoption of the chamfering tool for chamfering has high efficiency, good quality and low technical requirements, so that the chamfering tool can be widely promoted and used.
Description
Technical field
The invention belongs to field of machining, particularly a kind of chamfering tool of forward inner hole of taper shank.
Background technology
45 ° of chamfer machining of existing workpiece forward, no suitable cutter.The general following endoporus multi-use bit of φ 40mm chamfering, but the drill bit chamfer quality is unsatisfactory, uses the angle grinding machine also bad to the Hole chamfering effect below the φ 100mm.
Summary of the invention
The purpose of chamfering tool of forward inner hole of taper shank of the present invention provides a kind of cutter of processing work endoporus forward chamfering, and this chamfering tool manufacturing is simple, with low cost, easy to use.
The present invention is achieved in that chamfering tool of forward inner hole of taper shank of the present invention by taper shank, and blade is formed, and is mounted with blade in the groove of taper shank lower end, and the shape of blade is that the lower end is the fan-shaped of right angle.
The invention has the beneficial effects as follows: the part endoporus forward chamfering problem that has solved general material, comprise the processing of Hole chamfering in the material workpiece such as iron and steel, cast iron, copper material, aluminium, can process all workpiece endoporus forward chamferings from φ 20mm-φ 140mm size section, this chamfering tool manufacturing is simple, and cost is low, adopts chamfering tool of forward inner hole of taper shank chamfering of the present invention, the efficient height, quality is good, and specification requirement is not high, can extensively promote the use of.
Description of drawings
Fig. 1 is the front view of chamfering tool of forward inner hole of taper shank of the present invention;
Fig. 2 is the side view of Fig. 1.
The specific embodiment
The invention provides 45 ° of chamfering tools of a kind of processing, solved the part endoporus forward chamfer machining problem of general material, comprise the processing of Hole chamfering in the material workpiece such as iron and steel, cast iron, copper material, aluminium, can process all workpiece endoporus forward chamferings from φ 20mm-φ 140mm size section.
Chamfering tool of forward inner hole of taper shank of the present invention, as shown in Figure 1 and Figure 2, by taper shank 1, blade 2 is formed, and is mounted with blade 2 in the groove of taper shank 1 lower end, and the shape of blade 2 is that the lower end is the fan-shaped of right angle.
In the reality, dog screw, nut 4 link together taper shank 1 and high-speed steel blade 2 by the hole of taper shank 1 lower end and the hole at high-speed steel blade 2 middle parts; Two high-speed steel blades 2 are stacked, and by two holes of two trip bolts, nut 3 by high-speed steel blade 2 both sides, two blades 2 are linked together; Two blade 2 bottoms are processed into 90 ° of shapes respectively, and the cutting edge portion on 90 ° of limits processes anterior angle, relief angle.Taper shank 1 is No. 5, a Mohs awl, and No. 45 steel, fine grade can be used with radial drilling machine main shaft endoporus; High-speed steel blade 2 adopts two standard cutter blades scrapping, its external diameter φ 150mm, internal diameter φ 32mm, thick 5mm.Two of cutting plate for milling cutters cut into 90 ° of profiles respectively, and two through holes of processing are used for the installation of trip bolt and nut 3 on blade, and the blade cutting edge position grinds anterior angle, relief angle, is used for cutting and chip removal.In the use, it is too tight that the dog screw nut needn't be adorned, so that solid tool can be finely tuned in use naturally.The endoporus of the big workpiece of big workpiece 5 expression processing in the accompanying drawing is as φ 140mm; Small workpiece 6 is expression processing endoporus than small workpiece, as φ 20mm.
Claims (1)
1. chamfering tool of forward inner hole of taper shank is characterized in that: by taper shank, blade is formed, and is mounted with blade in the groove of taper shank lower end, and the shape of blade is that the lower end is the fan-shaped of right angle.
