Abstract
The utility model discloses a multipurpose milling cutter type drill bit which is a combination of a drill bit and a spiral column plain milling cutter. The utility model is characterized in that the utility model is provided with a cutting cutter tooth of a drill bit end head and the guide part is the structure of the spiral column plain milling cutter, namely, an end land edge is a column edge of the milling cutter provided with a front and a back surfaces. The milling cutter is multipurpose, and the multipurpose milling cutter type drill bit can not only drill holes, but also process a plane as the column plain milling cutter. The precision and the finish of hole walls are improved, and simultaneously, the rigidity, the vibration resistance, the guidance quality and the service life of the milling cutter are also improved. The utility model can be widely used for the job processing of various machines.
Description
The utility model is the combination of a kind of milling cutter and drill bit, belongs to the mechanical cutting tool class.
Fluted drill is to use the widest a kind of drill bit at present, and by cutting tip, targeting part and coupling part are formed.Cutting tip and targeting part all become the operate portions of drill bit.Operate portions has two helicla flutes, and whole drill bit only has two cutters tooth in the work termination, forms the cutting of vertical feed direction.There are following deficiency in its function of this drill bit and aspect of performance:
Participate in cutting when 1, drill bit is only made rotation and vertical feed rectilinear motion on the plane of vertical drilling rod, can only hole or reaming function singleness.
2, unbearable diameter increases from the cutting tip to the shank gradually.Unbearable diameter is little, and targeting part has a back draught in addition, influences drill bit rigidity, vibration resistance and guiding stability thereof.
3, the geometric parameter of cutting edge sharply changes, and particularly front edge changes more outstanding.
4, be zero degree in (on the payable at sight cutting edge) its relief angle on the seamed edge sword, form friction in the work on hole wall, the wearing and tearing of aggravation drill bit influence hole wall precision and fineness.
The utility model purpose is to disclose a kind of multi-use bit with milling function, is the combination of a kind of plain spiral milling cutter and drill bit.
Below be this case technical essential.
The tip of this device is the cutting tip of former drill bit, and its targeting part is the plain spiral milling cutter structure, and promptly the seamed edge sharpening of former drill bit has been made angle, certain front and back, forms the cylinder sword of plain milling cutter.Afterbody can be according to being designed to staight shank with the lathe connected mode, shapes such as tapering caudal peduncle or the threaded taper shank of tapering.
Angle before and after its seamed edge sword of the targeting part of drill bit has had, form the milling cutter sword, had cutting to hole wall, this device is except that keeping the boring function, can also process doing the plane on the vertical direction of aperture by similar plain milling cutter, had the new function of plain milling cutter, and improved hole wall precision and the fineness and the steering capability of boring, improved rigidity, vibration resistance and service life and the stock-removing efficiency of drill bit simultaneously.
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is Fig. 1 vertical view;
Accompanying drawing 3 is Figure 1A-A cutaway view.
Accompanying drawings the utility model embodiment
In order to keep drill bit chip removal ability, helical flue of drill still is two.The work termination is a double-pole tooth 1.The cutter tooth tapering can grind and be required angle and shape.2 is main cutting edge.3 is helicla flute.More than form drill bit main cutting part 4.Targeting part 5.Equal diameter cylinder for zero draft.The seamed edge sharpening is made angle, certain front and back, and anterior angle is 10 °～5 °, and relief angle is 8 °～12 °.Thereby form the cylinder sword of plain milling cutter.Can do plane processing to the vertical direction of hole axle.Coupling part 6 can be the threaded taper shank shape of tapering.This installs the many usefulness of a cutter, promptly can machining hole again can the milling plane.Can be competent at rat holing, semicircle hole or on sphere, hole.Can also be widely used in manufacturing gear strip or teeth groove.
The actual use of the utility model confirms that effect is very good, has practical value.
Claims (1)
1, a kind of many with milling cutter formula drill bit, comprise cutting, lead and be connected three parts, the drill bit end is known boring cutting cutter tooth, and it is characterized in that: the seamed edge sharpening that former drill guide is divided is made angle, certain front and back, form the cylinder sword of plain milling cutter, have the plain milling cutter function.
