Utility model content
The purpose of this utility model is to solve present stage when assembling column or cylindrical workpiece, the clamping of existence loosely, the shortcoming easily loosened, and a kind of sleeve fixture proposed.
To achieve these goals, the utility model have employed following technical scheme:
A kind of sleeve fixture, it is characterized in that: comprise holder, holder is provided with the collet head spring that a side is mated connection, circumference uniform distribution one group fluting on the barrel of the opposite side of described collet head spring, between every two adjacent notch, the outside of barrel is equipped with a wedge, upper at collet head spring, downside is socketed a upper swivel nut and lower swivel nut respectively, swivel nut is connected cooperation with lower swivel nut by external thread sleeve on described, be connected in swivel nut on described one and close up the closing in cover coordinated with described collet head spring, the described medial surface closing up cover is provided with the lozenges with described wedge corresponding matching.
On the basis of technique scheme, following further technical scheme can be had:
Described upper swivel nut and lower swivel nut are provided with the contrary external screw thread of the hand of spiral.
Described external thread sleeve connects at least one handle.
Described holder also connects a fixed head, and described fixed head clearance is crossed connecting rod and is connected a fixture block, and fixture block and described upper swivel nut snap-fit engagement are fixed.
The lateral wall of upper swivel nut is provided with at least one draw-in groove, and described fixture block is the platy structure with draw-in groove corresponding matching, or described fixture block is closed or split ring, is provided with the projection of at least one and respective card slot snap-fit engagement at inwall that is closed or split ring.
Also be socketed a protective cover in the upside of described collet head spring, described protective cover center is provided with a through hole corresponding with the sleeve of collet head spring, and described protective cover blocks with described upper swivel nut and coordinates.
Described holder is platy structure, and holder is provided with and the corresponding connecting screw hole of described collet head spring, is also fixedly connected with an auxiliary fixing plate in the downside of holder, auxiliary fixing plate is connected with described collet head spring and coordinates.
When clamping work pieces, external thread sleeve is driven to rotate, because described upper swivel nut and lower swivel nut are provided with the contrary external screw thread of the hand of spiral by turning handle, improve operating efficiency, reduce labour intensity, the above swivel nut of institute and the relative motion on external thread sleeve of lower swivel nut, collet head spring utilizes the upper and lower motion of the cover that closes up, collet head spring is made to shrink or open, collet head spring is fixed on fixed head, when clamping work pieces, upper swivel nut moves, the wedge closed up on cover extruded sleeve collet chuck spring, clamping work pieces.When needs unclamp workpiece, only need rotate in the opposite direction handle, upper swivel nut moves down, and closing in cover unclamps collet head spring.
The utility model has the advantage of: this device can by column or cylindrical workpiece clamping, folder spring clamping column or cylindrical body cylindrical, even circumferential stress during clamping, lifting surface area is large, column or the frictional force between cylindrical workpiece and sleeve jig is made to become large, thus workpiece is not loosened in sleeve jig, well can ensure product quality again.
