Abstract
The invention discloses an adjustable eccentric device for a self-centering chuck. The adjustable eccentric device is composed of a positioning shaft, a bottom plate and a rotating disc which are sequentially connected through a small head and a large head, a small eccentric hole matched with the small head is formed in the bottom plate, a large eccentric hole matched with the large head is formed in the rotating disc, the eccentric distance of the small eccentric hole is identical to that of the large eccentric hole, and the positioning shaft is sleeved with the bottom plate and the rotating disc through the small eccentric hole and the large eccentric hole respectively. An arc T-shaped groove is formed in the end face, opposite to the rotating disc, of the bottom plate, and a threaded through hole matched with the arc T-shaped groove is formed in the rotating disc. The self-centering chuck is fixed on the outer end face of the rotating disc. The adjustable eccentric device has the advantages that workpiece hole center positioning is accurate, use is convenient, and the self-centering chuck can be switched into a common self-centering chuck for use.

Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of adjustable eccentric device for self-centering chuck of new structure, make it have more value in industry.
Summary of the invention:
Object of the present invention is intended to solve prior art Problems existing, provides a kind of workpiece hole centralized positioning accurate, easy to use and the adjustable eccentric device for self-centering chuck that common self-centering chuck can be switched to use.
The present invention relates to a kind of adjustable eccentric device for self-centering chuck, comprise the locating shaft be connected successively with major part by microcephaly, the chassis offering the small eccentricity hole coordinated with described microcephaly, offer the rotating circular disk in the large eccentricity hole coordinated with described major part, described small eccentricity hole is consistent with the eccentric throw in large eccentricity hole, and described chassis and rotating circular disk are located on locating shaft respectively by small eccentricity hole and large eccentricity borehole jack; End face relative with rotating circular disk on described chassis offers arc T-slot, described rotating circular disk offers the tapped through hole coordinated with described arc T-slot; The outer face of described rotating circular disk is fixed with self-centering chuck.
Preferred as such scheme, the described tapped through hole center of circle, the rotating circular disk center of circle, locating shaft axle center are on the same line.
Preferred as such scheme, described rotating circular disk is locked through tapped through hole and arc T-slot and chassis by clamping screw.
Preferred as such scheme, the diameter of described rotating circular disk is identical with the diameter of self-centering chuck.
Preferred as such scheme, the outer face of described rotating circular disk be provided with boss with configure self-centering chuck seam, be provided with three screw hole cartridge screws and self-centering chuck is fastenedly connected.
Preferred as such scheme, the outer face on described chassis offers seam and three screwed holes for assembling lathe dish.
Preferred as such scheme, described chassis is provided with balance weight.
Preferred as such scheme, the diameter in described small eccentricity hole is 30mm, and eccentric throw is 20mm.
Preferred as such scheme, the diameter in described large eccentricity hole is 40mm, and eccentric throw is 20mm.
By such scheme, the present invention at least has the following advantages: the present invention due on chassis, rotating circular disk, offer the consistent eccentric orfice of eccentric throw respectively and with locating shaft assembly connection, rotate around locating shaft by rotating rotating circular disk, can location eccentricity distance easily, by the cooperation of T-slot, tapped through hole, can rotating circular disk be fastened on chassis according to required eccentric throw effective location, Workpiece clamping can be carried out eccentric processing on self-centering chuck, after being made zero by rotating circular disk position of rotation, can also not eccentric processing be carried out; The present invention greatly facilitates processing eccentric work piece, as long as mobile rotating circular disk or self-centering chuck just can adjusts process eccentric work piece, when common self-centering chuck uses after zero, left and right transposition and eccentric processing, more large eccentricity distance is larger for corner, maximumly reaches 15mm.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
Accompanying drawing illustrates:
The following drawings is only intended to schematically illustrate the present invention and explain, not delimit the scope of the invention.Wherein:
Fig. 1 is front view of the present invention;
Fig. 2 is the sectional view of A-A line in Fig. 1;
Fig. 3 is eccentric processing working state schematic representation of the present invention.
Detailed description of the invention:
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
See Fig. 1, Fig. 2, adjustable eccentric device for self-centering chuck of the present invention, comprise the locating shaft 1 be connected successively with major part 12 by microcephaly 11, the chassis 2 offering the small eccentricity hole (not shown) coordinated with described microcephaly 11, offer the rotating circular disk 3 in the large eccentricity hole (not shown) coordinated with described major part 12, described small eccentricity hole is consistent with the eccentric throw in large eccentricity hole, and described chassis 2 and rotating circular disk 3 are located on locating shaft 1 respectively by small eccentricity hole and large eccentricity borehole jack; End face relative with rotating circular disk 3 on described chassis 2 offers arc T-slot 4, rotating circular disk 3 offers the tapped through hole 5 coordinated with described arc T-slot, on the same line, rotating circular disk 3 is locked with chassis 2 through tapped through hole 5 and arc T-slot 4 by clamping screw 6 for described tapped through hole 5 center of circle, rotating circular disk 3 center of circle, locating shaft 1 axle center.
The outer face of rotating circular disk 3 be provided with boss 31 with configure self-centering chuck 7 seam, be provided with three screw hole 32 cartridge screws and self-centering chuck 7 is fastenedly connected, the diameter of rotating circular disk 3 is identical with the diameter of self-centering chuck 7; The outer face on chassis 2 offers seam 21 and three screwed holes 22 for assembling lathe dish.
