Abstract
The utility model discloses a milling cutter clamping tool composed of a main body, a linking nut, hard pawls, soft pawls, an auxiliary main body, a detachable bearing end cover and roller balls. The main body and the auxiliary main body are respectively provided with six tapered slots; each tapered slot is provided with a T-shaped slot; three hard pawls and three soft pawls are respectively provided with convex slots which are coordinated with the T-shaped slots; the auxiliary main body is driven to move to the direction of the main body by screwing the linking nut; three hard pawls and three soft pawls arranged between the main body and the auxiliary main body are gathered to a milling cutter handle arranged on the inner holes of the main body and the auxiliary main body and then pressed tightly; the structure model is suitable for various milling cutters; the utility model has high clamping work strength; the utility model is not easy to loose after clamped.
Description
The utility model relates to a kind of milling machine milling fixture.
Existing milling cutter clamping tool is to add a corresponding with it spring housing of size on milling cutter (rounded); Putting the awl tail of milling machine then into locks with nut again.It is that external force effect by nut makes spring housing (afterbody is tapered) and milling machine tapered sleeve generation crimp clamp milling cutter.Thereby needed intensity when just having been possessed work by the milling cutter of clamping, yet no doubt possessed enough intensity with this form clamping milling cutter, but when the milling cutter of clamping different size, just must change corresponding with it spring housing, and when changing spring housing, must firmly beat the spring housing that is removed, could take out, so make troubles to mechanic! The three jaw self-centering clamping heads that on traditional lathe, drilling machine, percussion drill, possessed can any different size of clamping (within the specific limits) milling cutter, if just do not have the needed working strength of milling cutter but these common drill bits are used on the milling machine, that is to say the not tight milling cutter of the basic just folder of these drill bits when milling cutter is worked, and the geometry of drill chuck itself do not possess the working strength of milling machine yet.
The purpose of this utility model is to provide a kind of and is applicable to various milling cutters, clamps the high milling fixture of working strength.
For achieving the above object, milling fixture of the present utility model is made up of main body, interlock nut, hard pawl, soft pawl, attached main body, removable bearing (ball) cover, ball, the endoporus that is screwed into the main body in the interlock nut is provided with six identical skewed slots of its gradient that evenly distribute on every side, and the top of skewed slot is provided with " fourth " word groove; Be provided with a straight hole between skewed slot and the skewed slot, be provided with six identical skewed slots of its gradient that evenly distribute around the endoporus by ball and attached main body in removable bearing (ball) cover is connected the interlock nut, the top of skewed slot is provided with " fourth " word groove; Be provided with a latch that matches with the main body straight hole between the skewed slot of attached main body and the skewed slot, one end of hard pawl and soft pawl is provided with the tongue that matches with " fourth " word groove on the main body skewed slot, the other end is provided with the tongue that matches with " fourth " word groove on the attached main body skewed slot, and hard pawl interlocks with soft pawl and is assemblied on main body and the attached main body; Soft pawl is made up of soft pawl housing, shell fragment, "T"-shaped, and this "T"-shaped is located in the soft pawl housing, and shell fragment is located between them, one side make outside the soft pawl housing of "T"-shaped stretch out.
After adopting such structure, after in milling fixture, putting into milling cutter, turn the interlock nut, driving attached body by ball moves to main direction, at this moment three hard pawls, three soft pawls slide in " fourth " word groove of main body, attached main body respectively, six pawls are drawn in to the centre, and compress to the milling cutter of centre, this mode just can be put into the milling cutter of different sizes, thereby reaches clamping, the high effect of clamping working strength that is applicable to different milling cutters.
Fig. 1 is the structural representation of a kind of embodiment specifically of the present utility model,
Cutaway view when Fig. 2 changes 90 ° for Figure 1A place,
Fig. 3 is Figure 1B-B cutaway view.
Form by main body 1, interlock nut 2, hard pawl 3, soft pawl 4, attached main body 7, removable bearing (ball) cover 9, ball 8 as Fig. 1, Fig. 2, milling fixture shown in Figure 3, the endoporus that is screwed into the main body 1 in the interlock nut 2 is provided with six identical skewed slot hearts of its gradient that evenly distribute on every side, and the top of skewed slot is provided with " fourth " word groove 5; Be provided with a straight hole 17 between skewed slot and the skewed slot, the endoporus that is connected the attached main body 7 in the interlock nut 2 by ball 8 and removable bearing (ball) cover 9 is provided with six identical skewed slots 19 of its gradient that evenly distribute on every side, and the top of skewed slot is provided with " fourth " word groove 10; Be provided with a latch 18 that matches with main body 1 straight hole 17 between the skewed slot 19 of attached main body 7, one end of hard pawl 3 and soft pawl 4 is provided with the tongue 6 that matches with " fourth " word groove 5 on main body 1 skewed slot 15, the other end is provided with the tongue 11 that matches with " fourth " word groove on attached main body 7 skewed slots 19, hard pawl 3 and soft pawl 4 staggered being assemblied on main body 1 and the attached main body 7; Soft pawl 4 by soft pawl housing 14, shell fragment 13, form for "T"-shaped 12, this "T"-shaped 12 is located in the soft pawl housing 14, shell fragment 13 is located between them, one side make outside the soft pawl housing 14 of "T"-shaped 12 stretch out.During use, milling cutter is put into anchor clamps, promptly be placed on the centre of main body 1 and attached main body 7, hard pawl 3 that assembles and soft pawl 4, "T"-shaped 12 on the soft pawl 4 is subjected to shell fragment 13 effects, make "T"-shaped 12 and stretch out outside the soft pawl housing 14, make soft pawl 4 exceed certain size slightly than hard pawl 3, when rotation interlock nut, the latch 18 of attached main body 7 matches with the straight hole 17 of main body 1, drive moving of attached main body 7 straight lines by ball 8 to main body 1 direction, at this moment three hard pawls 3 and three soft pawls 4 on main body 1 " fourth " word groove 5 and " fourth " word groove 11 of attached main body 7 in slide, thereby hard pawl 3 and soft pawl 4 draw in to the centre, wherein three soft pawls are clamped milling cutter earlier, because three soft pawls have the elasticity of certain intensity, ajust in the centre after making milling cutter that the tightening force effect be arranged, hard then pawl clamps milling cutter subsequently, and when six pawls receipts power clamping simultaneously milling cutter shank, when three reverse tensions that soft pawl produced clamp milling cutter shank, three reverse tensions that soft pawl produced disappear between main body 1 and the interlock nut, and it can prevent that anchor clamps from can not become flexible after clamping the milling cutter driving.This frame mode is applicable to the clamping of various milling cutters, and clamping working strength height is not easy to become flexible.
