Abstract
The utility model relates to a milling cutter, to be specific, a compound dislocation milling cuter. The existing dislocation milling cutter, under the condition of unvaried main axle angle, can only process the plane that is vertical to or in parallel with the axis of the main axle and can not process oblique surface and chamfer angle. In processing the oblique surface or chamfer angle, the main axle case of the existing dislocation milling cutter shall be adjusted for certain angle or the workpiece shall be placed to a oblique angle, which results in much inconvenience for the adjustment of the machine tool and the clamping of the positioning clamp. The utility model is characterized in that: a taper body is positioned at the lower section of the utility model; even number chutes are positioned on the taper body; the bottom surface of the chute parallels with the busbar of the taper body; the lateral edge of the cutter e parallels with the busbar of the taper body; the cutters in nearby chutes of the cutter body are arranged in misalignment; the front edge of the cutter can be adopted to process the end surface; the lateral edge of the cutter can be adopted to process the oblique surface at the same time. Therefore, the utility model saves the time for the readjustment of the machine tool or repositioning the clamping workpiece and, enhances the working efficiency as well.
Description
Technical field
The utility model relates to a kind of milling cutter, a kind of specifically indexable composite milling cutter.
Background technology
Existing indexable milling cutter, under the isogonal situation of main shaft, can only process the plane perpendicular or parallel with main-shaft axis, can not directly process inclined-plane and chamfering, need change main spindle box an angle or, tightly cause a lot of inconvenience when processing inclined-plane or chamfering to lathe adjustment and work piece positioning the tilting angle of workpiece.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provides a kind of high efficiency, does not need to adjust the indexable composite milling cutter of lathe and workpiece when processing vertical plane and inclined-plane at the same time.
The technical scheme that its technical problem that solves the utility model adopts is achieved in that the top of milling cutter body is cylinder, endoporus is arranged on the cylinder, end face has the keyway that is connected with machine tool chief axis, the bottom of cutter hub is a cone, the skewed slot that even number is arranged on cone, the bottom surface of skewed slot is parallel with the bus of cone, edge bearing is housed in skewed slot, the protuberance of edge bearing back withstands the end face of circular groove on the cutter hub, in the groove of edge bearing blade is housed, the side tool sword of blade is parallel with the bus of cone, by contract piece and screw edge bearing and blade are clamped in the skewed slot, on the cutter hub in the adjacent skewed slot position of the groove of edge bearing be and be in staggered distribution, the interior edge bearing of a skewed slot of being separated by on the cutter hub is identical, blade on the cutter hub in the adjacent skewed slot is side set and distributes, promptly in a skewed slot n blade is housed, n+1 or n-1 blade separated by a distance just is housed in its adjacent skewed slot, the distance of being separated by is less than the width of blade, adjacent two skewed slot inner blades be distributed with overlay region, the width that the quantity of side set distribution blade and width depend on inclined-plane to be processed.Skewed slot on the cutter hub has step, and the bottom surface of step is parallel with the bus of cone, and a side of blade leans against the step bottom surface.Blade is indexable, and the work edge wearing and tearing indexable use in back of blade is work edge not.
The beneficial effects of the utility model are, processing vertical plane and inclined-plane can carry out simultaneously, saved the time of adjusting lathe or reorientating clamping work pieces, improved efficient, need the quantity of the blade that the width on processing inclined-plane can distribute with side set to guarantee, the cone of cutter hub bottom has different taperings, can satisfy the requirement of various processing gradients.Use standard insert, avoided making the trouble of special-purpose blade.

The specific embodiment
Embodiment 1
Further specify below in conjunction with accompanying drawing, as Fig. 1: the top of milling cutter body cutter hub 1 is cylinder, endoporus is arranged on the cylinder, end face has the keyway that is connected with machine tool chief axis, the bottom of cutter hub is a cone, the tapering of cone is consistent with the gradient on the inclined-plane that will process, even number band step skewed slot is arranged on cone, the bottom surface of step is parallel with the bus of cone in the skewed slot, edge bearing 5 and edge bearing 6 are housed in skewed slot, the protuberance of edge bearing back withstands the end face b of circular groove a on the cutter hub, blade 2 is housed in the groove of edge bearing, one side of blade upper knife edge is close to the bottom surface of step in the skewed slot, makes the side tool sword d of blade parallel with the bus of cone, by contract piece 4 and screw 3 edge bearing and blade is clamped in the skewed slot, on the cutter hub in the adjacent skewed slot position of the groove of edge bearing be and be in staggered distribution, blade also is side set and distributes, and as edge bearing 5 and edge bearing 6, makes blade be side set and distributes; A blade is housed on the edge bearing 5 in a skewed slot, on the edge bearing 6 in its adjacent skewed slot two blades separated by a distance are housed, the distance of being separated by makes the overlay region that is distributed with of adjacent two skewed slot inner blades less than the width of blade, and the edge bearing in the skewed slot of being separated by on the cutter hub is identical; Blade is indexable, and the work edge wearing and tearing indexable use in back of blade is work edge not.
Can with side edge d processing inclined-plane, also can process simultaneously on the end face inclined-plane with front edge c processing end face during use.
Embodiment 2
The difference of present embodiment and embodiment 1 is on the interior edge bearing of a skewed slot blade to be housed, and on the edge bearing in its adjacent skewed slot a blade is housed also, and two blades are side set and distribute, and the overlay region is arranged.Be applicable to the narrower workpiece in processing inclined-plane.
Embodiment 3
This enforcement is on the interior edge bearing of a skewed slot two blades to be housed with the difference of embodiment 1, on the edge bearing in its adjacent skewed slot three blades is housed, and blade is side set and distributes, and the overlay region is arranged.Be applicable to the workpiece of processing inclined-plane broad.
