The beneficial effects of the utility model are: structure is simple, attended operation is convenient, be conducive to quick assembling location, reduce installation time, and avoid disfiguring workpiece endoporus, can take inner hole of workpiece as locating surface again simultaneously, improves the quality of workpieces in subsequent processing.
Further, described plug one end stretched in described centre bore is polygonized structure, and the structure of described centre bore is the polygonized structure with described plug mating shapes.
Further, described plug one end stretched in described centre bore is square structure, and the structure of described centre bore is the square hole with described plug mating shapes.
Further, described plug and described centre bore are matched in clearance.
Adopt the beneficial effect of above-mentioned further scheme to be: to be conducive to preventing plug and index dial from relative rotation phenomenon occurring, make orientation assemble more accurately firm.
Further, described index dial is provided with packing ring away from one end of described plug, and described locking member stretches in described plug through described packing ring.
Further, described index dial is provided with mounting groove away from one end of described plug, and described packing ring is arranged in described mounting groove, and described locking member rotates when tightening pushes down described packing ring.
Further, described locking member is soket head cap screw.
The beneficial effect of above-mentioned further scheme is adopted to be: locking member adopts that soket head cap screw is easy to operate, cost is low, mounting groove is set pad is installed, the replacing being convenient to pad is installed, and reduces the wearing and tearing to index dial when locking member is locked simultaneously, improves the whole service life of frock.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.
Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in Figure 1, the utility model clamping device comprises the index dial 1 that plug 2 is connected with plug 2 with one end, and index dial 1 is provided with the centre bore axially running through index dial 1.One end of index dial 1 is stretched in the large stomidium of workpiece 5 endoporus, index dial 1 and workpiece 5 endoporus adopt matched in clearance, adopt index dial 1 to stretch into the advantage positioned in the endoporus of workpiece 5 and be that the length of index dial 1 is shorter, touch the screw thread that the fine finishining of workpiece 5 endoporus completes when index dial 1 can be avoided to stretch into workpiece 5 endoporus, avoid the defective work piece 5 endoporus structure such as accurately machined screw thread.The little stomidium of workpiece 5 endoporus is passed in one end of plug 2, and plug 2 and workpiece 5 endoporus adopt matched in clearance, plug 2 and index dial 1 all adopt small―gap suture to coordinate with workpiece 5, make the center line of workpiece 5 and frock centerline on same straight line, guarantee that the size of the journal stirrup of workpiece 5 and endoporus centre-to-centre spacing is accurate, improve location crudy.
As shown in Figure 1, plug 2 extend in the centre bore of index dial 1 through after workpiece 5 endoporus, and is locked by locking member 4, and locking member 4 can adopt soket head cap screw to be locked.Plug 2 one end stretched in centre bore is polygonized structure, and the structure of centre bore is the polygonized structure with plug 2 mating shapes.In the present embodiment, plug 2 stretches into the cross sectional shape perpendicular to axial direction of the one end in centre bore for square, the structure of centre bore is the square hole with plug 2 mating shapes, plug 2 and centre bore are matched in clearance, adopt square structure and matched in clearance installation, avoiding plug 2 to be there is relative rotation in index dial 1.Index dial 1 is provided with packing ring 3 away from one end of plug 2, and locking member 4 stretches in plug 2 through packing ring 3.Index dial 1 is provided with mounting groove away from one end of plug 2, and packing ring 3 is arranged in mounting groove, and packing ring 3 can be changed according to abrasion condition, pushes down packing ring 3 and avoids the index dial 1 that weares and teares, improve the service life of this clamping device when locking member 4 rotation is tightened.
