Some workpiece utilizing milling machine to process has two orthogonal groove millings, and the clamping operation of this workpiece is more complicated.During workpiece such as shown in manuscript 1 and Fig. 2, just need to carry out twice clamping, the horizontal groove milling 16(of first time clamping aft-loaded airfoil or longitudinal groove milling 17), until horizontal groove milling 16(or longitudinal groove milling 17) after completion of processing, workpiece must be unloaded, longitudinal groove milling 17(or horizontal groove milling 16 could be processed) after re-starting clamping, because second time clamping should ensure the positional precision of workpiece, consider the perpendicularity of two groove millings again, therefore clamping difficulty can be larger, so just greatly reduces the working (machining) efficiency of workpiece.Therefore, be necessary to design a kind of fraise jig that can carry out quick-clamping to the workpiece with vertical groove milling, to improve working (machining) efficiency and the machining accuracy of this type of workpiece.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of fraise jig, to improve working (machining) efficiency and the machining accuracy of the workpiece with two vertical groove millings.
Problem described in the utility model realizes with following technical proposals:
A kind of fraise jig, formation comprises base plate, base, central minor axis, apotting spindle, alignment pin and pressing plate, described base plate is fixed on milling machine, the bottom center of described base is rotationally connected by central minor axis and base plate, and the fastening bolt by arranging around central minor axis between base with base plate is fixedly connected with; Described apotting spindle is inserted in the through hole of workpiece to be processed, and its one end is fixedly connected with base; Affixed with base on the locating surface that described alignment pin leans against workpiece; Described pressing plate is pressed on workpiece, and its one end is bolted on base.
Above-mentioned fraise jig, also comprises Screw tail cone pin in formation, and described Screw tail cone pin is arranged in the locating hole of base and base plate.
Above-mentioned fraise jig, also comprises feeler block in formation, and described feeler block to be positioned on base by straight pin and to be fixedly connected with base by feeler block hold-down screw.
Above-mentioned fraise jig, the fastening bolt between described base and base plate arranges individual, and their distribute along even circumferential coaxial with central minor axis.
Above-mentioned fraise jig, the described base plate one side corresponding with milling machine is provided with positioning key.
Above-mentioned fraise jig, described fastening bolt is T-slot bolt.
The utility model utilizes apotting spindle and alignment pin to position workpiece, and utilizes pressing plate by Work-sheet pressing.Only base need be rotated corresponding angle around central minor axis during processing second groove milling, so just enormously simplify clamping operation, thus improve working (machining) efficiency and the machining accuracy of workpiece.
