The double-cone spring chuck device is high in clamping precision and is especially suitable for clamping elongated workpieces.
Description
Technical field
The utility model relates to lathe collet device, relates in particular to a kind of bipyramid collet device.
Background technology
In machining, collet is widely used in the clamping of workpiece.But for the workpiece of elongated shaft location, common single awl collet is because the retaining part area is less, can not obtain good grip adding the easy skew of workpiece in man-hour.
The utility model content
Goal of the invention: to the deficiency that prior art exists, the utility model provides a kind of slender piece that is specially adapted to, and has the bipyramid collet device of high clamping precision.
Technical scheme: to achieve these goals; The utility model is through following technical scheme: a kind of bipyramid collet device is characterized in that: the guide rod, bipyramid collet, sliding sleeve and the tapered sleeve that comprise the pull bar, the tie-plate that are nested in the machine tool chief axis, be fixed on collet body on the front-end of spindle face, establish in the cylindrical shape screw thread; Said pull bar one end is connected with oil cylinder, and the other end is connected with swivel nut; Said swivel nut is fixed through connecting flange and tie-plate, and said tie-plate and main shaft end face are preset with the slit, and this tie-plate is connected with guide rod simultaneously; Said collet body is flanged cylinder, and this flange is provided with the through hole that supplies guide rod to pass, and the inwall of this collet body is provided with the conical surface simultaneously, and the bottom of this conical surface outwardly; Said sliding sleeve is set in the outer wall of collet body, and is fixedly connected with guide rod; Said bipyramid collet two ends are equipped with the taper jaw, and place in the collet body; Said tapered sleeve inwall is provided with the conical surface, and fixes with the sliding sleeve end face.
Because pull bar, swivel nut, connecting flange, tie-plate, guide rod, sliding sleeve and tapered sleeve fuse; When pull bar during in oil cylinder effect tighten; Thereby the final tapered sleeve that drives is oppressed the taper jaw clamping work pieces that the bipyramid collet makes its outer end, and the bipyramid collet pushes the taper jaw clamping work pieces on the inner that forces the bipyramid collet along the conical surface of collet body inwall simultaneously.Therefore the clamping area of workpiece is big, can obtain high clamping precision.
Further improvement as technique scheme; The outer surface of the taper jaw at said bipyramid collet two ends matches with collet body conical surface of inboard wall and tapered sleeve conical surface of inboard wall; Therefore make that the chucking power of bipyramid collet when the clamping workpiece is more even, piece-holder is more stable.
Another kind as technique scheme improves, and said tapered sleeve cylindrical is evenly equipped with two above screws, and said screw is furnished with screw.Through the adjustment screw screw-in depth, thereby the fine setting tapered sleeve makes the axis of cone line of tapered sleeve inwall consistent with collet body axis of cone line, guarantees the clamping precision of workpiece.
Continuation improves such scheme, and said collet body is equipped with dust cover on the outer face, and the contact-making surface of this dust cover and said sliding sleeve is provided with sealing ring.Therefore can iron filings and cooling fluid access to plant inside.
Beneficial effect: compared with prior art, the utlity model has following advantage: 1, because the area of clamping workpiece is bigger, chucking power is more even, thereby piece-holder is more stable, has high clamping precision; 2,, can prevent that iron filings and cooling fluid access to plant are inner through dust cover and sealing ring.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model technical scheme is elaborated, but the protection domain of the utility model is not limited to said embodiment.
As shown in Figure 1, a kind of bipyramid collet device comprises pull bar 1, swivel nut 2, connecting flange 3, tie-plate 4, collet body 5, guide rod 6, bipyramid collet 7, dust cover 8, sliding sleeve 9, sealing ring 10 and tapered sleeve 11.Said pull bar 1 is nested in the machine tool chief axis 12, and an end connects with oil cylinder, and the other end is threaded with swivel nut 2, on these swivel nut 2 end faces, is provided with two grooves, can itself and pull bar 1 is fixing through spanner; Said connecting flange 3 is a convex; And its cylindrical is provided with screw thread; This connecting flange 3 passes swivel nut 2, and its cylindrical is threaded with said tie-plate 4 simultaneously, thereby tie-plate 4 and swivel nut 2 are fused; And tie-plate 4 leaves the slit with main shaft 12 end faces, is threaded with four guide rods 6 through screw on said tie-plate 4 circumference; Described collet body 5 is flanged cylinder; This cylinder inner wall is provided with the conical surface; And conical surface major part outwardly, and the flange of collet body 5 is provided with the through hole that supplies guide rod 6 to pass simultaneously, and this collet body 5 passes guide rod 6 and fixes through the through hole and main shaft 12 front end faces that evenly are arranged on the flange; Said sliding sleeve 9 is set on collet body 5 outer walls; And it is fixing through screw and guide rod 6; And be provided with the conical surface in the said tapered sleeve 11, and fix with sliding sleeve 9 screws, so far; Swivel nut 2, connecting flange 3, tie-plate 4, guide rod 6, sliding sleeve 9 and tapered sleeve 11 are connected in aggregates with pull bar 1, can move and move with pull bar 1; Said bipyramid collet 7 places in the double end conical cavity that collet body 5 and tapered sleeve 11 form, and the two ends of this bipyramid collet 7 are equipped with the taper jaw, and the conical surface of the conical surface of this taper jaw and double end conical cavity matches; Simultaneously be provided with four screws uniformly on said tapered sleeve 11 cylindricals, and corresponding screw is installed makes it consistent with the axis of cone line of collet body 5 in order to the axis of cone line of adjustment tapered sleeve 11; Dust cover 8 is installed on collet body 5 outer faces at last, and is provided with sealing ring 10 between the contact-making surface of this dust cover 8 and sliding sleeve 9.
Because pull bar 1, swivel nut 2, connecting flange 3, tie-plate 4, guide rod 6, sliding sleeve 9 and tapered sleeve 11 fuse, when pull bar 1 tension, thereby finally drive the taper jaw clamping work pieces that tapered sleeve 11 compressing bipyramid collets 7 make its outer end; Bipyramid collet 7 is along collet body 5 inner moving simultaneously, and the taper jaw receives the extruding of collet body 5 conical surfaces, thereby forces the taper jaw clamping work pieces of the inner of bipyramid collet 7, thereby realizes the clamping to workpiece.
