The chuck is through screw two, straight pin two loaded on active index dial.
The mandrel is step, and mandrel one end actively indexes center hole interference fits, mandrel with the axle of machining center four
The other end and Three-jaw chuck for lathe centre bore interference fits.
The chuck hub and active index dial central coaxial.
The guide sleeve external diameter and driven indexing center hole interference fits.
The compressor arm is to do the gap that the grade of tolerance is H7/f6 to coordinate with guide sleeve.
The chamfered section is rounding.
The utility model instead of present technique with a set of frock required for a few set frocks, use is relatively compact, light
Frock instead of present heavy, thick frock, it is only necessary to which a machining center, which just instead of present technique, needs several processing
The process that center could complete.The utility model reduces frock, equipment, the input of personnel, has saved fund cost；This practicality
It is new that present several manufacturing procedures are placed in a manufacturing procedure, reduce with time of same cutter and reduce plus
The clamping times of work part, so as to save time cost.
The utility model is solved with mounting hole or positioned with External Shape, it is desirable to the mounting hole increase precision of part,
And frock requires higher, it is impossible to the problem of ensureing axiality requirement well.Compared with prior art, the utility model does not have to
The positioning compression system of machining center bridge plate and complexity, and reduce frock input.The utility model is simple in construction, can make
The position degree and symmetry of the cross bore of part can preferably ensure.

Embodiment
In Fig. 1, the utility model includes the pair of four axle index dial of machining center one, the positive dog chuck of lathe three-jaw 2 one, car
The positive pair of pawl one of bed three-jaw, locating rod 4 one, guide sleeve 7 one, 6 one, fast-holding bar, mandrel 10 1, handle 9 one
Individual, four axle index dial of machining center one is secondary to include the axle active index dial 1 of machining center four, the driven index dial 8 of the axle of machining center four
Each one.The one end of mandrel 10 and the centre bore interference fits of four axle active index dial of machining center 1, the one end of mandrel 10 and lathe are with three
The positive dog chuck centre bore interference fits of pawl.The positive dog chuck 2 of lathe three-jaw passes through 4-6 screw 11 and straight pin and machining center
Four axle active index dials 1 are fixed.The positive center of dog chuck 2 of lathe three-jaw and the central coaxial of four axle active index dial of machining center 1.
When the positive pawl 3 of lathe three-jaw is in minimum state, lathe is machined to small with the single order of the front end on the positive pawl 3 of three-jaw
In the internal diameter for being connected thereto part.Bored on the positive pawl 3 of lathe three-jaw and attack a screwed hole, locating rod 4 one end car, one M12 screw thread
