Reference numeral title: 1, handle of a knife body 2, handle of a knife staight shank portion 3, handle of a knife connector 4, nut 5, milling cutter 6, collet chuck 7, annular groove 8, dust ring 9, annular slot 10, projection 11, inclined-plane 12, inner cone inclined-plane 13, external decoration inclined-plane.
Detailed description of the invention
Just with reference to the accompanying drawings the utility model is further described below.
As shown in Figure 1, a kind of high accuracy handle of a knife clamping device, comprise a handle of a knife body 1, one end of handle of a knife body 1 has a handle of a knife staight shank portion 2, and the end in handle of a knife staight shank portion 2 is provided with a handle of a knife connector 3, and handle of a knife connector 3 outer surface thread connects a nut 4, the collet chuck 6 of a fixing milling cutter 5 is provided with in the middle part of handle of a knife connector 3, outer 3 surfaces of handle of a knife connector are provided with an annular groove 7, are provided with a dust ring 8, the upper end-face edge of collet chuck 6 and nut 4 clamping in annular groove 7.The utility model adopts dust ring, prevents man-hour iron filings from entering handle of a knife and nut tooth position adding, can not cause the phenomenon of card tooth during dismantle; Add man-hour anti-skidding, shockproof, considerably reduce frictional force when screw thread rotation, during lock cutter, nut serves very heavy load effect in handle of a knife.
Preferably, front end 41 external diameter of nut 4 is greater than nut 4 rear end 42 external diameter.Mainly prevent wholecircle spanner from can not fall on position, handle of a knife staight shank portion 2.
Preferably, the inwall of nut 4 is provided with a ring-shaped step 43, and this ring-shaped step 43 is resisted against the upper end of handle of a knife connector 3.Because the gap of ridge is comparatively large, so location, design two ends controls the effect of not beat when handle of a knife body 1 is assembled with nut 4.
Preferably, the end edge of collet chuck 6 is provided with an annular slot 9, and the inwall of nut 4 is provided with the projection 10 with annular slot 9 clamping.
Preferably, collet chuck 6 is inclined-plane 11 with the contact surface of nut 4, and the gradient on this inclined-plane 11 is 60 °.Main Function is and collet chuck 6 outer cone contact of incline plane, when locking with handle of a knife inner cone, collet chuck 6 outer cone rotating gripper and collet chuck 6 be out of shape to reduce and clamp the effect that milling cutter 5 completes processing
Eight, 8 milling cutter tests coordinate the collet chuck of 3 μ within 4 times of length, and LER handle of a knife clamps 5 μ precision, within remaining on 5 years; The gradient on collet chuck 6 inclined-plane 11 is 60 ° of effects is engage with nut 4 when rotating to clamp milling cutter, the collet chuck 6 of 3 μ, with TER handle of a knife clamping coordinate, precision with 5 μ within be the first-selection of processing electronic product; The outer fenestra of nut 4 is spanner position, adopts full grinding to prevent from reducing windage during High-speed machining, reducing noise.
