Description
Technical field
The utility model relates to milling cutter, particularly a kind of Novel replaceable T-slot cutter.
Background technology
In the every field of machine industry, the processing of T-slot occupies considerable part.Comprise all kinds of keyway, parts assembling mating groove, lathe high accuracy guide-track groove, oil-way lubrication groove, endoporus packing ring and groove of cooling down, mold component fluting, non-standard molding groove etc.The processing of T-slot can adopt turning by its executable processing mode, boring, the main processing mode of milling three class.Along with the development in science and technology in each field of China and the progress of manufacturing, T-slot tool its precision, efficiency, requirement on be badly in need of improve, cost be also badly in need of reduce.
Current cutting tool basic material is mainly high-speed steel, carbide alloy, pottery, and this three classes material is in its rigidity, each has something to recommend him in hardness, toughness.Be mainly high-speed steel and carbide alloy at T-slot class Milling Process cutter, frame mode is mainly entirety and welding.
It is high that the Milling Process of T-slot generally has required precision, and processing easily shakes, to cutter rigid requirements high.High-speed steel T-slot cutter efficiency and the life-span lower, the surface quality processed is not fine; Whole hard alloy T-slot cutter cost is higher, can reduce costs although welded, requires the welding quality controlling cutter, there is the risk of sealing-off in process.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides the Novel replaceable T-slot cutter that a kind of structure is simple, easy to use.
The purpose of this utility model is achieved through the following technical solutions: a kind of Novel replaceable T-slot cutter, comprise knife bar and cutter head, knife bar is provided with installation end, the side of installation end is two planes and two cambered surfaces, two planes are positioned opposite, cutter head is provided with the installing hole matched with installation end in center, one end of installing hole is provided with cutter head installed surface, the center of installation end has screwed hole, the opening part of screwed hole is provided with knife bar installed surface, cutter head is connected with knife bar with installation end cooperation by installing hole, cutter head is compressed by using screw to coordinate to install with screwed hole.
Described cutter head installed surface is the conical surface with knife bar installed surface and tapering is identical, and the end diameter of cutter head installed surface is not more than the outside diameter of knife bar installed surface.
Described screw is sunk screw.
Described knife bar, installation end and cutter head are coaxial.
Described cutter head is that Hardmetal materials is made.
The utility model has the following advantages:
1. adopt split-type structural, make cutter head interchangeable, cutter head handling are simple, can prevent cutter head from coming off, rupturing, and simplify tool sharpening technique;
2. cutter head adopts Hardmetal materials to make, such that its working (machining) efficiency is high, long service life;
3., by using plane to coordinate with plane, cambered surface coordinates with cambered surface, and make cutter head repeated clamping positioning precision high, torque transmission efficiency is high, and utilization of mechanical energy rate is high;
4. axial direction adopts the centripetal cooperation of the conical surface to make interchangeable T-slot cutter head installation accuracy high with the mode be threaded, good stability.

Fig. 2 is the structural representation of cutter head;
Fig. 3 is the structural representation of installation end;
Fig. 4 is the structural representation of screw;
In figure, 1-knife bar, 2-installation end, 3-cutter head, 4-cutter head installed surface, 5-knife bar installed surface, 6-screwed hole, 7-screw.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of Novel replaceable T-slot cutter, comprise knife bar 1 and cutter head 3, knife bar 1 is provided with installation end 2, the side of installation end 2 is two planes and two cambered surfaces, two planes are positioned opposite, cutter head 3 is provided with the installing hole matched with installation end 2 in center, one end of installing hole is provided with cutter head installed surface 4, the center of installation end 2 has screwed hole 6, the opening part of screwed hole 6 is provided with knife bar installed surface 5, cutter head 3 is connected with knife bar 1 with installation end 2 cooperation by installing hole, cutter head 3 is compressed by using screw 7 to coordinate to install with screwed hole 6.
As shown in Figure 1, in the present embodiment, described cutter head installed surface 4 is the conical surface with knife bar installed surface 5 and tapering is identical, the end diameter of cutter head installed surface 4 is not more than the outside diameter of knife bar installed surface 5, screw 7 can be made can to compress cutter head installed surface 4 with this, after avoiding screw 7 to contact with knife bar installed surface 5, cutter head installed surface 4 cannot be contacted.
As shown in Figure 4, in the present embodiment, described screw 7 is sunk screw, this cutter can be made to avoid screws contact part man-hour adding with this, and because the nut portion of sunk screw is taper, when cutter head is installed, the centripetal cooperation of the conical surface can be realized, improve installation accuracy, be conducive to ensureing machining accuracy.
In the present embodiment, described knife bar 1, installation end 2 and cutter head 3 are coaxial, can ensure with this stationarity adding man-hour, prevent vibrations.
In the present embodiment, described cutter head 3 is made for Hardmetal materials, can improve working (machining) efficiency and increase the service life with this.
