Specific embodiment
In conjunction with summary of the invention general introduction and attached drawing, the specific embodiment that the present invention will be described in detail.
A kind of cross bore drilling tool is converted to rotation center by the way that rotating mechanism is arranged, solves its cross bore and symmetrical holes
Processing technology problem.Part is positioned using common plane and two pits, finds out the rotation center of workpiece, one side here, by
The outermost plain line group of outer semicircle is constituted on workpiece to be processed, and machining accuracy is that can be used to position when free tolerance requires.But such as
Fruit cross bore required precision is higher, it is necessary at workpiece to be processed suitable position, reserve technique auxiliary boss, and improve it and add
Work precision, for increasing auxiliary positioning precision.The machining accuracy for guaranteeing subsequent handling hole, after subsequent handling operation completion, then
Removal, reaches the final structure required precision of part.
Cross bore drilling tool includes positioning component, common Anchor plate kit, rotating mechanism, drilling tool benchmark main body, drill jig board group
The composition such as part.Positioning component includes diamond positioning pin 11, cylindrical positioning pins 12, positioning rotating plate 14.Common Anchor plate kit includes pressure
Plate 9 adjusts support 10, studs 13.Rotating mechanism includes positioning component, shaft 2, nut 4, locking pin 20.Further include
