The utility model solves its technical problem and takes following technical scheme to realize：
A kind of lathe four-way precise locating fixture, it is characterised in that：Including fixture mount, lower clip arm, upper clip arm, positioning
Post and adjusting screw, fixture mount upper end are formed with the lower clip arm of the semicircular arc that a upper end is opening, the radial direction of the lower clip arm
One end is hinged with upper clip arm by hinge, and upper clip arm is relative with lower clip arm to form an annular holder when fastening, and workpiece is by marmon clamp
The center of tool passes through；Four positioning of radial direction are installed uniformly at intervals inside the annular holder that upper fixture and lower clamp are formed
Post, one end of locating dowel penetrates the inside of annular holder and a nylon cushion block is internally fixed with termination, locating dowel it is another
One end rotary spacing has the adjusting screw in an outside for passing annular holder, and adjusting screw is engaged by screw thread and is arranged on upper clip arm
Or the outside of lower clip arm.
And, the fixture mount bottom is rotated coaxially in a support shaft, and the support shaft is packed in a bottom vertically
On seat, bolt hole is preset on base.
And, it is movably installed with connecting bolt in the radial direction other end of upper clip arm and lower clip arm.
And, locating dowel passes through the end that annular nested structure rotary spacing is arranged on adjusting screw, locating dowel and regulation
Screw can be rotated and can not relatively moved.
And, a banking pin is symmetrically installed with the annular holder of both sides before and after the locating dowel, banking pin is corresponding
A slide-and-guide groove is formed with locating dowel.
Advantage of the present utility model and good effect are：
It is the utility model simple structure, easy to operate, positioning work can be fastened with four length of locating dowel of accurate adjustment
Part, from the center of accurate limiting workpiece, is effectively ensured the axiality of workpiece work in-process, it is ensured that machining accuracy, and lifting adds
Work efficiency rate.
