Abstract
The utility model relates to a milling cutter. The adjustable three-edge milling cutter is composed of a main cutter body and more than one mobile cutter bodies. The mobile cutter bodies and the main cutter body are mutually clamped into a whole in an axial direction and can be moved in the axial direction. A plurality of three-edge tool bits capable of moving up and down and right and left are arranged on each cutter body. The utility model has the advantages that the width size processed by the milling cutter can be randomly adjusted within a certain rang; the tool bits can be used in a convertible way; special non-standard cutting tools need to be manufactured to process some non-standard grooves of special purposes; the production efficiency is improved; the intensity of labor is reduced; the inventory and the consumption of the tool bits are reduced.
Description
The utility model relates to a kind of milling cutter.
Existing standard face and side cutter, be divided into whole high-speed steel and carbide alloy iron chains tooth two big classes, all belong to traditional structure, its specification is all fixed, and promptly a kind of milling cutter of specification can only be processed a kind of groove of size, produces needs for satisfying like this, factory, workshop just need have the milling cutter of all size size, increased the quantity in stock of cutter virtually, increased occupied fund, produced in the use also very inconvenient.Because the size of each groove on the processing parts is all inconsistent, so just need change cutter repeatedly, has not only directly influenced production efficiency, and has increased working strength of workers.And must reface or change after the cutter head of existing standard face and side cutter repeatedly uses and to continue to use, also increase the consumption of cutter.
The purpose of this utility model is to provide a kind of adjustable face and side cutter at the deficiency of prior art existence, and the width dimensions of its processing can be adjusted arbitrarily in certain scope.The convertible use of cutter head, and, no longer need to make special-purpose non-standard cutting tool to the processing (as the groove of odd number and mixed decimal size) of the non-standard groove of some specific uses.
The utility model is realized by the following technical solutions: a kind of adjustable face and side cutter, it is characterized in that: by a slice operator body with the mobile cutter hub more than a slice is axially interlaced is fastened togather and can moves axially, the cutter head that three faces that some handles can move up and down put the first edge on a knife or a pair of scissors is installed on every cutter hub.
Cutter head 1 is an equilateral triangle, all puts the first edge on a knife or a pair of scissors in three limits, and it is 60 ° groove that cutter head location supporting plate 3 one ends have the angle that adapts with cutter head 1, and cutter head 1 is put into this groove and located, and cutter head 1 and cutter head location supporting plate 3 are fixed on the cutter hub by cutter head compact heap 15.Cutter head 1 can be realized radially finely tuning by cutter head set screw 2, and cutter head location supporting plate 3 moves screw 14 by the cutter holder and can axially finely tune, and the Pingdu of assurance cutter head axial vane surface and cutter head be axiality radially.
Mobile cutter hub 5 central openings, in be with a cutter hub travelling nut 7, near mobile cutter hub 5 one sides, on nut 7, also be screwed with a calibration loop 6, opposite side at calibration loop 6 also is screwed with a gap adjustment ring 8 to withstand cutter hub travelling nut 7, eliminates the gap between mobile cutter hub 5 and the cutter hub travelling nut 7.Operator body 4 central authorities be extended with one with cutter hub travelling nut 7 hollow screw that adapts, by cutter hub travelling nut 7 operator body 4 and mobile cutter hub 5 are bonded together so that the form of thread connection is axially staggered.
The afterbody of operator body 4 hollow screw is screwed with a cutter hub friction nut 10, cutter hub friction nut 10 is fixed on the hollow screw of operator body 4 by knife bar keyway fixed screw 9, and the keyway on the knife bar during knife bar keyway fixed screw 9 can be twisted and be passed hollow screw and stretch into screw rod is connected, and plays the stationary adjustable face and side cutter.
After the milling cutter size adjusting is good, the gap that cutter hub fixed screw cover 11, cutter hub fixed screw 12 can be eliminated the thread connection between operator body 4 and the mobile cutter hub 5, by frictional force that it is locked.
The cutter holder is moved screw steady pin 13 and screw 14 is moved in the cutter holder is fixed on the cutter hub.
Cutter head compact heap 15 is fixed on the cutter hub by two screws 16, can loosen or tighten move up and down.
Advantage of the present utility model is: the width dimensions of milling cutter processing can be adjusted arbitrarily within the specific limits; The convertible use of cutter head; Can not need make special-purpose non-standard cutting tool and process the non-standard groove of some specific uses; Improve production efficiency, reduced labour intensity, reduced the consumption of tool magazine storage and cutter hub material, saved the workload of tool sharpening.Enlarge the processing range of common face and side cutter.
Description of drawings:
Accompanying drawing 1 is a novel structure vertical view of the present utility model
Accompanying drawing 2 be Fig. 1 along A-A to cutaway view
Accompanying drawing 3 be Fig. 1 along B-B to cutaway view
Embodiment: as Fig. 1～shown in Figure 3
Adjustable face and side cutter, by two axially staggered be fastened togather and can axially movable operator body 4 and mobile cutter hub 5 form.Be equipped with four on the every cutter hub and be equilateral triangle, the put the first edge on a knife or a pair of scissors carbide bit of machine clip variable-position formula of three faces.
Operator body 4 and mobile cutter hub 5 can carry out the adjustment of axial width dimension, and adjusting range is 0～10mm, and size can be regulated arbitrarily therebetween.Calibration loop 6 is arranged on the cutter hub, and every lattice are 0.04mm, and after size mixed up, cutter hub was locked by four cutter hub fixed screws 12.
The angle that compresses of cutter head 1 is 20 °, and cutter head compact heap about 15 has a draft angle.When milling cutter penetration of a cutting tool, cutting force can carry out secondary locking to cutter head, to eliminate the end play of movable tool rest.
The screw that one M8 is arranged on cutter hub drag ring 10 connects with the keyway of this and milling cutter knife bar, plays a key piece fixation and prevents milling cutter idle running.
The maximum depth of cut of this milling cutter is 40mm, and Breadth Maximum is 25mm, and revolution is up to 600 rev/mins, and maximum feed is 190mm second.
Each parts of cutter and blade non-loosening after cutting, cutting effect is good, and workpiece fineness reaches 6, and dimensional accuracy is stable.
