Description
Technical field
The utility model relates to the mechanical device technical field of Metal Cutting Machine Tool, and relating in particular to a kind of digital control vertical machining tool product processing is the quick high accuracy detent mechanism of benchmark with the hole.
Background technology
At present domestic vertical machining centre is tapered sleeve location or the cylinder rhombus location of adopting when the fine finishining of product is located with the hole more, because tapered sleeve and cylinder rhombus pin are rigid member, processing and positioning accuracy request height to tapered sleeve, cylinder rhombus pin and datum hole, and reduce at tapered sleeve and cylinder rhombus pin wearing and tearing back precision, thereby influence processing can't guarantee the product required precision.
Summary of the invention
The purpose of this utility model provide a kind of can be to carrying out accurate detent mechanism with hole location and the uncertain product in aperture.Can locate fast and the precision height, and can compensate, realize self-centering size radially.
The purpose of this utility model is achieved in that by base, jack-up spring, inner cone piece, centering ball, positioning core axle, pressing plate, guide pad, screw, swelling cover, locking nut are formed, positioning core axle and base are that interference fit is accurately located, product to be processed is placed on the base plane, the jack-up spring is placed in the groove of base, four guide pads are fixed on the base by screw, and the inner cone piece is placed on the base plane, and inner cone piece and swelling cover are cone match.
The inner cone piece is made up of impartial four parts, locatees with centering ball between the each several part.
For realizing purpose of the present invention, the compensation detent mechanism of a kind of self-centering provided by the invention, comprise base, the jack-up spring, the inner cone piece, centering ball, positioning core axle, pressing plate, guide pad, swelling cover and locking nut, wherein guide pad is fixed on the base by screw, positioning core axle and base interference fit realize accurately location, swelling cover endoporus cooperates with positioning core axle, swelling cover male cone (strobilus masculinus) and inner cone piece inner conical surface are joined work, the external diameter of inner cone piece cooperates with the product diameter of bore, the axis that guarantees product endoporus center and positioning core axle is realized accurately location at same center.The present invention is by being divided into the inner cone piece four impartial parts, and inner cone piece inner conical surface is with after the swelling cover cooperates, and under the effect of locking nut, four impartial partly prolongs guide pad bore expansion in product, thereby reaches radial compensation, realizes self centering purpose.
Because the utility model adopts said structure, can locate fast and the precision height, and can compensate size radially, realize self-centering.Has advantage simple in structure, easy to process, that reliability is high.

After product processing, unclamp locking nut 10, jack-up spring 2 jack-up swellings cover 9 promotes inner cone piece 3 outer rims, and inner cone piece 3 is shunk inwardly, can conveniently lift by crane product.
Fig. 3 and Fig. 4 are swelling cover view, and swelling is enclosed within to process on the general Digit Control Machine Tool and gets final product.
Fig. 5 and Fig. 6 are inner cone piece view, and the inner cone piece is after integral body processing, and line cuts into impartial four parts again.
Claims (2)
1. compensation detent mechanism of self-centering, by base, jack-up spring, inner cone piece, centering ball, positioning core axle, pressing plate, guide pad, screw, swelling cover, locking nut are formed, positioning core axle and base are that interference fit is accurately located, product to be processed is placed on the base plane, and the jack-up spring is placed in the groove of base, and four guide pads are fixed on the base by screw, the inner cone piece is placed on the base plane, it is characterized in that: inner cone piece and swelling cover are cone match.
