Abstract
The utility model discloses a double-cone elastic sleeve self-centering locking mechanism which comprises a clamp body, a compression spring, an elastic sleeve and a locking nut, wherein the elastic sleeve of the double-cone elastic sleeve self-centering locking mechanism is matched in an inner taper hole of the clamp body through the conical surface at one end; the conical surface at the other end of the elastic sleeve is matched with an inner taper hole of the locking nut; the locking nut is in clearance fit with an outer cylinder of the clamp body through a hole shaft; an internal thread connected with an external thread of the clamp body is arranged on the locking nut; axial movement generated by rotating the locking nut compresses the elastic sleeve to radially contract and clamp a part; the compression spring is arranged at the end part of the elastic sleeve matched with the conical surface of the clamp body; the locking nut when loosened pushes the elastic sleeve to restore a free state; when in use, the conical surfaces of the locking nut and the clamp body compress the elastic sleeve to move radially, and the part is locked on the total length of an inner hole of the elastic sleeve; and bidirectional contraction slots are uniformly formed along the axial direction of the elastic sleeve so as to provide an elastic deformation and contraction space for the radial contraction of the elastic sleeve.
Description
Technical field
The utility model relates to a kind of axial workpiece self-centering fixture, belongs to the machine driving adjusting device, is mainly used in axial workpiece self-centering clamping.
Background technology
In the axial workpiece clamping, self-centering chuck or the resilient sleeve structures of adopting more, resilient sleeve is used more extensive when the cylindrical of axle is orientated smart benchmark as, the elastic conical drogue that mostly is greatly that uses at present cooperates the location, big end end face axial compresses, the radial contraction of elastic conical drogue influences positioning accuracy at big small end lack of homogeneity.
Summary of the invention
Be the better self-centering clamping that realizes axial workpiece, the utility model provide a kind of simple in structure, interchangeability good, precision keeps stable, wieldy bipyramid resilient sleeve self-centering retaining mechanism, bipyramid face by resilient sleeve contacts with conical bore, resilient sleeve is evenly shunk the locking part on contact length, realize that accurately the location clamps.
The technical solution of the utility model is: be used for the self-centering clamping bipyramid resilient sleeve self-centering retaining mechanism of axial workpiece, comprise clamp body, compression spring, resilient sleeve, locking nut.The resilient sleeve of described bipyramid resilient sleeve self-centering retaining mechanism is passed through an end cone match in the internal taper hole of clamp body, the other end conical surface of resilient sleeve cooperates with the internal taper hole of locking nut, locking nut is engaged on the outside cylinder of clamp body by between centers crack, hole, the axiality of the inner conical surface of assurance locking nut and the inner conical surface of clamp body, being provided with internal thread on the locking nut simultaneously connects with the external screw thread of clamp body, the rotational lock nut overlaps radial contraction clamping part by the elasticity of compression that moves axially of locking nut.Described resilient sleeve is provided with the compression spring in the end with the clamp body cone match, and compression spring device promotes resilient sleeve and replys free state in the blind hole of clamp body when locking nut unclamps, be convenient to the mounting or dismounting of part.
During application, unclamp the locking nut shaft parts of packing into, the rotational lock nut, conical surface elasticity of compression cover radial displacement by locking nut and clamp body, lock part in resilient sleeve endoporus total length, described resilient sleeve has uniform two-way retraction slot, the strain when satisfying the resilient sleeve radial contraction and shrink space vertically.
Description of drawings
Accompanying drawing 1 is the utility model bipyramid resilient sleeve self-centering retaining mechanism schematic diagram.
The specific embodiment
Referring to accompanying drawing, the utility model provides a kind of bipyramid resilient sleeve self-centering retaining mechanism, comprises clamp body 1, compression spring 2, resilient sleeve 3, locking nut 4.
The resilient sleeve 3 of described bipyramid resilient sleeve self-centering retaining mechanism is passed through an end cone match in the internal taper hole of clamp body 1, the other end conical surface of resilient sleeve 3 cooperates with the internal taper hole of locking nut 4, locking nut 4 is engaged on the outside cylinder of clamp body 1 by between centers crack, hole, the axiality of the inner conical surface of assurance locking nut 4 and the inner conical surface of clamp body 1, being provided with internal thread on the locking nut 4 simultaneously connects with the external screw thread of clamp body 1, rotational lock nut 4 overlaps 3 radial contraction clamping part by the elasticity of compression that moves axially of locking nut 4.
Described resilient sleeve 3 is provided with compression spring 2 in the end with clamp body 1 cone match, compression spring 2 devices promote resilient sleeve and reply free state in the blind hole of clamp body when locking nut 4 unclamps, be convenient to the mounting or dismounting of part.
