Abstract
The utility model provides a compound milling cutter, which has a milling cutter with big diameter, and is characterized in that a hole is arranged on the center of the head portion of the milling cutter with big diameter, the side of a cutter body is equipped with a tapping hole and a puller bolt, and a milling cutter with small diameter is arranged in the hole and is pulled by the puller bolt. The compound milling cutter has the advantages that cutters and machined parts are clamped in one time, two kinds of holes or grooves with different diameter or width can be continuously processed, the auxiliary time for replacing the cutters or aligning the machined parts is reduced, the machining efficiency and the processing quality of the machined parts are increased and the like.
Description
Technical field
The utility model belongs to the Machining Technology field, specially refers to a kind of composite milling cutter.
Background technology
In the Machining Technology field, car, mill and plane etc. is a technology the most basic in the machining.General employing cutter all is a standard in milling process, cutter commonly used has finger type milling cutter, cylindrical bar milling cutter and dish-type milling cutter etc., usually in the processing of a part, the different big or small keyway or the hole of part often need to use multiple and the different size milling cutter is processed.Part to be processed as depicted in figs. 1 and 2, part need be processed semicircle orifice R12mm, need to process the keyway of 10mm simultaneously, when the such part of common Milling Process, need to use two milling cutters of the diameter that varies in size to process, the Working position that so just needs replacing cutter that the workman do not stop or the centering part that does not stop, processing parts is very long non-cutting time, and adopt the positional precision of such cutter and processing method institute processing parts to be difficult to be guaranteed, and the part of being processed generation percent defective is bigger.
Summary of the invention
The purpose of this utility model is the problem and shortage of the part of the above-mentioned type in the Milling Process existence, provides a kind of and once is installed, and shortens the non-cutting time of changing cutter or centering part to be processed, improves the composite milling cutter of working (machining) efficiency and part to be processed crudy.
Technical solutions of the utility model are for achieving the above object:
A kind of composite milling cutter comprises the major diameter milling cutter, it is characterized in that: described major diameter milling cutter head center is porose, and the blade side has tapping hole and adorns puller bolt, adorns a minor diameter milling cutter in the hole, and is held out against by puller bolt.
A kind of composite milling cutter of utility model is compared with existing plain cutter, has the following advantages:
1, simple in structure, be convenient to make, it is low to make the cost of charp tool;
2, once be installed cutter and part to be processed can be processed two kinds of different holes of size diameter or width or groove continuously, shortly change non-cutting time cutter or the centering part to be processed, improve working (machining) efficiency and part to be processed crudy;
3, cutter sharpening again, it is comparatively convenient to repair.Because large and small cutting edge is relatively independent separately, if certain part wearing and tearing or damage can be decomposed and be taken sharpening, repairing or replacing apart.
Description of drawings
Fig. 1 is the schematic diagram of part to be processed;
Fig. 2 is that the C of part to be processed is to enlarged diagram;
Fig. 3 is a kind of composite milling cutter master of the utility model diagrammatic sketch;
Fig. 4 is a kind of composite milling cutter side view of the utility model.
Among the figure: the plane 6 that is held out against on the hole 5 of the carbide chip 4 of major diameter milling cutter 1, minor diameter milling cutter 2, bolt 3, major diameter milling cutter, the head center of major diameter milling cutter, the handle of minor diameter milling cutter.
The specific embodiment
Be elaborated with regard to the specific embodiment below in conjunction with accompanying drawing.
As shown in Figure 3 and Figure 4, a kind of composite milling cutter of the utility model.Composite milling cutter is made up of two milling cutters of the diameter that varies in size; Major diameter milling cutter 1 has Morse taper shank, the major diameter milling cutter is welded with carbide chip 4, and the head center of major diameter milling cutter is porose 5, and blade has tapping hole and adorns a puller bolt 3, in the hole 5 of major diameter milling cutter, adorn a minor diameter milling cutter 2, and hold out against by puller bolt.On the handle of described minor diameter milling cutter, be provided with and be used for the plane 6 that held out against.
When a kind of composite milling cutter of the utility model is used for processing parts, part to be processed as depicted in figs. 1 and 2, on milling machine, only need just can once be installed and finish the keyway of processing semicircle orifice R12mm and 10mm with a composite milling cutter, guaranteed the status requirement of the keyway of part to be processed first circular hole R12mm and 10mm, and saved the non-cutting time of changing cutter, improve working (machining) efficiency.
Claims (2)
1, a kind of composite milling cutter comprises major diameter milling cutter (1), it is characterized in that: described major diameter milling cutter head center porose (5), blade side have tapping hole and adorn puller bolt (3), adorn a minor diameter milling cutter (2) in hole (5), and are held out against by puller bolt.
2, a kind of composite milling cutter according to claim 1 is characterized in that: the handle of described minor diameter milling cutter is provided with and is used for the plane (6) that held out against.
