Abstract
The invention 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 invention relates to a kind of axial workpiece self-centering fixture, belongs to machine driving adjusting device, is mainly used in axial workpiece self-centering clamping.
Background technology
In axial workpiece clamping, self-centering chuck or the elastic sleeve structures of adopting more, when the excircle orientation of axle is smart benchmark, resilient sleeve application is more extensive, the elastic conical drogue that is mostly using at present coordinates location, large end end face axial compresses, the radial contraction of elastic conical drogue, at large small end lack of homogeneity, affects positioning precision.
Summary of the invention
For better realizing the self-centering clamping of axial workpiece, the invention provide a kind of simple in structure, interchangeability good, precision keeps stable, wieldy bipyramid resilient sleeve self-centering locking mechanism, Double-conical-surface by resilient sleeve contacts with conical bore, resilient sleeve is evenly shunk locking part on contact length, realizes accurately location and clamps.
The technical scheme of the invention is: the self-centering clamping bipyramid resilient sleeve self-centering locking mechanism for axial workpiece, comprises clamp body, Compress Spring, resilient sleeve, locking nut.The resilient sleeve of described bipyramid resilient sleeve self-centering locking mechanism is passed through one end cone match in the internal taper hole of clamp body, the elastomeric other end conical surface coordinates with the internal taper hole of locking nut, locking nut passes through the little matched in clearance of hole axle in the outside cylinder of clamp body, guarantee the axiality of the inner conical surface of locking nut and the inner conical surface of clamp body, on locking nut, be provided with internal thread connects with the external screw thread of clamp body simultaneously, rotational lock nut, overlaps radial contraction clamping part by the elasticity of compression that moves axially of locking nut.Described resilient sleeve is being provided with Compress Spring with the end of clamp body cone match, and compression spring device, in the blind hole of clamp body, promotes resilient sleeve and replys free state when locking nut unclamps, and is convenient to the mounting or dismounting of part.
During application, unclamp locking nut and pack shaft parts into, rotational lock nut, by the conical surface compresses elastomeric radial displacement of locking nut and clamp body, in elastomer endoporus total length, lock part, described elastomer has uniform way contracting groove, the strain while meeting elastomer radial contraction and shrink space vertically.
