Description
Technical field
The utility model relates to Machining Technology field, especially a kind of die case for gear ring boring.
Background technology
Gear ring is when installing fixedly, normally by the circular hole of fixed gear ring end face.Thereby the processing of circular hole is absolutely necessary, yet being all a class gear ring Drilling operation, the processing of existing gear ring needs a set of drilling die sleeve, and production efficiency is lower, and production cost is high.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of die case for gear ring boring.
The technical scheme in the invention for solving the technical problem is: a kind of die case for gear ring boring, comprise holder, positioning seat and mandrel, described positioning seat is provided with for locating the V-type circular groove of gear ring, positioning seat is installed on holder by screw, described mandrel is from holder bottom through holder and positioning seat, it is characterized in that, also comprise bore template, pressing plate, locking nut and gear ring, described gear ring is positioned at the V-type circular groove of positioning seat, described bore template is nested on mandrel and compresses described gear ring, described pressing plate is placed on mandrel and compresses described bore template, described locking nut is twisted in mandrel top and is compressed described pressing plate.
Further, described holder middle part offers a conical bore, and the bottom part aperture diameter of conical bore is greater than aperture, top, and described conical bore top is cylindrical hole, and cylindrical hole aperture equates with aperture, conical bore top.
Further, described mandrel lower end is cone, and the conical bore of its tapering and described holder matches, and middle part is cylinder, and top is provided with screw thread.
Further, described bore template is provided with some nibs for gear ring boring.
Further, described positioning seat middle part is provided with circular hole, described circular hole aperture and mandrel barrel portion equal diameters.
Further, described bore template middle part is provided with circular hole, described circular hole aperture and mandrel barrel portion equal diameters.
The beneficial effects of the utility model: adopt after said structure, can realize fast the positioning clamping to gear ring, to carry out end face Drilling operation, can meet the gear ring processing of different-diameter simultaneously.
Accompanying drawing explanation
Fig. 1 is wind three-dimensional structure diagram of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is the A-A cutaway view in Fig. 2;
In figure: 1 holder, 2 positioning seats, 3 bore templates, 4 pressing plates, 5 locking nuts, 6 mandrels, 7 gear rings.
The specific embodiment
With reference to Figure of description 1, to 3 pairs of a kind of die cases for gear ring boring of the present utility model of accompanying drawing, be described in detail below.
A kind of die case for gear ring boring, comprise holder 1, positioning seat 2 and mandrel 6, described positioning seat 2 is provided with for locating the V-type circular groove of gear ring 7, positioning seat 2 is installed on holder 1 by screw, described mandrel 6 is from holder 1 bottom through holder 1 with positioning seat 2, it is characterized in that, also comprise bore template 3, pressing plate 4, locking nut 5 and gear ring 7, described gear ring 7 is positioned at the V-type circular groove of positioning seat 2, described bore template 3 is nested on mandrel 6 and compresses described gear ring 7, described pressing plate 4 is placed on mandrel 6 and compresses described bore template 3, described locking nut 5 is twisted in mandrel 6 tops and is compressed described pressing plate 4.
Further, described holder 1 middle part offers a conical bore, and the bottom part aperture diameter of conical bore is greater than aperture, top, and described conical bore top is cylindrical hole, and cylindrical hole aperture equates with aperture, conical bore top.
Further, described mandrel 6 lower ends are cone, and the conical bore of its tapering and described holder 1 matches, and described mandrel 6 middle parts are cylinder, and described mandrel 6 tops are provided with screw thread.
Further, described bore template 3 is provided with some nibs for gear ring 7 borings.
Further, described positioning seat 2 middle parts are provided with circular hole, described circular hole aperture and mandrel 6 barrel portion equal diameters.
Further, described bore template 3 middle parts are provided with circular hole, described circular hole aperture and mandrel 6 barrel portion equal diameters.
During use, directly gear ring 7 is put into the V-type circular groove of positioning seat 2, utilized the characteristic of V-type circular groove to realize location fast to gear ring, then load onto bore template 3, pressing plate 4 is also tightened locking nut 5, completes clamping, can carry out Drilling operation.
The above, be only the specific embodiment of the present utility model, and in the scope that those of ordinary skill in the art disclose at the utility model, the variation that can expect easily, within all should being encompassed in the protection domain of utility model.
