Abstract
The utility model discloses a multi-function composite center drill, which adopts a split structure that consists of a drill tip (1), a tightening screw (2) and a cutter body (3), wherein, the drill tip (1) is connected with the cutter body (3) through the tightening screw (2). The multi-function composite center drill has the advantages that a split structure is adopted, so that the loading and the clamping interchange is convenient and rapid, and the adaptability is high, and the production efficiency is high, and the cost of the cutting tool is low.
Description
Technical field
The utility model relates to a kind of aperture knife tool, particularly relates to a kind of combination centre drill of using more.
Background technology
At present, traditional big specification centre drill generally is weldment is made with whole high-speed steel or high-speed steel, be mainly used in the centre bore of the big part of processing, on the higher heavy parts of dimension precision requirement processing many by related size the hole or during screwed hole, also need to determine with this centre drill earlier the center in hole, so that guarantee the dimensional accuracy of workpiece, its structure as shown in Figure 2, wherein, E is the apex point part, end sword and Zhou Ren are arranged, and processing diameter is the straight hole part of D; F is the 60 ° of conical surface cutting edges in processing aperture; G is the cutting edge of the 120 ° of protection conical surfaces in processing aperture; H is a Morse taper shank, is connected with handle of a knife or lathe by the tapering cylindrical.The shortcoming of this class centre drill is: apex point part E participates in main cutting during use, so apex point part E very easily weares and teares, after apex point part E wearing and tearing, because of being difficult for reconditioning, the angle of apex point part E and 60 ° of conical surface F formation causes scrapping of centre drill integral body again, and the cutter utilization rate is lower.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of combination centre drill of using is provided more.This combination centre drill structure of the cutter body compactness, cut brisk, machined surface quality, it is convenient and swift that clamping is changed, and helps reducing production costs in enhancing productivity.
The purpose of this utility model is achieved through the following technical solutions: use combination centre drill more, it is characterized in that: described many be the split-type structural that constitutes by apex point, trip bolt and cutter hub with combination centre drill, apex point is connected with cutter hub by trip bolt.
Many differences with combination centre drill and traditional centre drill that the utility model provides are described many with combination centre drill employing branch body structure, install the back and rely on the Morse taper shank of cutter hub to be connected use with lathe.In the use, can select the high-speed steel apex point also can select the carbide alloy apex point according to the performance of machined material.
Apex point uses the wearing and tearing back only to need apex point is partly changed or reconditioning is reused, and it is convenient and swift to change the apex point part.Single apex point part reconditioning is very simple and convenient.So just saved production cost greatly.
It is identical and apex points that D is different are processed the straight hole in different apertures that same cutter hub also can assemble d, and can go out the 60 ° of conical surfaces in aperture and 120 ° of conical surfaces by ream boring the time, saved the process time of tool change time and workpiece, improved production efficiency.
If when taking main part apart 60 ° of conical surfaces of work or 120 ° of taper countersinks uses separately.Equally also can reconditioning reuse.Like this apex point part and cutter hub are partly taken apart and carried out compare with the reconditioning of integral central brill easy with regard to very of reconditioning.The good centre drill of reconditioning can be repeatedly use, reduce the cost of charp tool about 40%.
Many advantages with combination centre drill described in the utility model are: it adopts and divides body structure, and clamping exchanges convenient and swift, the applicability height, and the production efficiency height, the cost of charp tool is cheap.
Description of drawings
Fig. 1 uses the combination centre drill structural representation more
The structural representation of Fig. 2 traditional integral formula centre drill
Fig. 3 uses the split structural representation of combination centre drill more
Among the figure, 1-apex point, 2-trip bolt, 3-cutter hub, E-apex point part, D-apex point diameter, d-apex point shank diameter; The 60 ° of conical surface cutting edges in F-processing aperture; The cutting edge of the 120 ° of protection conical surfaces in G-processing aperture; The H-Morse taper shank,
The specific embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing: as Fig. 1 and Fig. 3, use combination centre drill, it is the split-type structural that is made of apex point 1, trip bolt 2 and cutter hub 3 more, and apex point 1 is connected with cutter hub 3 by trip bolt 2.
The many employing with combination centre drill described in the utility model divided body structure, installs the back and relies on the Morse taper shank of cutter hub to be connected use with lathe.In the use, can select the high-speed steel apex point also can select the carbide alloy apex point according to the performance of machined material.
Apex point uses the wearing and tearing back only to need apex point is partly changed or reconditioning is reused, and it is convenient and swift to change the apex point part.Single apex point part reconditioning is very simple and convenient.So just saved production cost greatly.
It is identical and apex points that apex point diameter D is different are processed the straight hole in different apertures that many same cutter hubs with combination centre drill described in the utility model also can assemble apex point shank diameter d, and can go out the 60 ° of conical surfaces in aperture and 120 ° of conical surfaces by ream in the time of boring, save the process time of tool change time and workpiece, improved production efficiency.
Take apart separately when doing 60 ° of conical surfaces or 120 ° of taper countersinks uses with the main part of combination centre drill if will be how.Equally also can reconditioning reuse.Like this apex point part and cutter hub are partly taken apart and carried out compare with the reconditioning of integral central brill easy with regard to very of reconditioning.The good centre drill of reconditioning can be repeatedly use, reduce the cost of charp tool about 40%.
Claims (1)
1, use combination centre drill more, it is characterized in that: described many be that apex point (1) passes through trip bolt (2) and is connected with cutter hub (3) by the split-type structural of apex point (1), trip bolt (2) and cutter hub (3) formation with combination centre drill.
