Description
Technical field
The utility model belongs to the Machining Technology field, and it is a kind of drill jig that bores inclined oil hole of air in the intermediate oil-in.
Background technology
The intermediate dead eye two ends of the used energy-saving and emission-reduction vitals of fuel engines turbocharger are the oilhole of bearing oil injecting lubricating, and not only the little degree of depth of diameter is big for this oilhole, and angle is all arranged.Employing numerical control machining center processing is not though the control method advanced person is its strong point to the processing of this class oilhole.Because during oblique drilling hole, drill bit is difficult to the location, must use earlier with drill bit end mill(ing) cutter of a size and on hole wall, mill out a sloping platform, and then boring.But oilhole generally all has only 2 millimeter, and cutter stretches into workpiece inside again, adds the distance of crossing over anchor clamps, and cutter all can only be a slender type, and this cutter rigidity is very poor, can't rapid feed, not only consume man-hour during use, and cutter fractures very easily also.
At this situation, can use cylindrical drill jig instead and directly be contained in the dead eye, adopt the pin location at the end face utilization middle oilhole parallel again with dead eye, drill jig can not be rotated, intermediate is placed on the bearing support consistent with the inclined oil hole of air angle.Utilize common bench drill and drill bit just can get out inclined oil hole of air, so not only greatly reduce man-hour, and the use cost of cutter and equipment also can reduce greatly.
But the various structures of booster intermediate are not quite similar, there is a kind of intermediate not have middle oilhole, do not have to utilize the place of location on the end face, its inclined oil hole of air is directly to connect oil-in and dead eye, and wherein inclined oil hole of air is not to pierce from dead eye but pierce from oil-in.Utilize the structure that is installed in the cylindrical drill jig in the dead eye just can not finish the purpose that gets out inclined oil hole of air so as stated above.
The utility model content
The purpose of this utility model provides a kind of drill jig that bores inclined oil hole of air in the intermediate oil-in that is drilled in common table.Bore inclined oil hole of air with this drill jig and have the advantage that technology is simple, cost is low, speed is fast, yield rate is high.
The technical solution of the utility model is: a kind of drill jig that bores inclined oil hole of air in the intermediate oil-in.It includes bearing support, positioning cylinder and cylinder drill jig.Positioning cylinder one end has boss, and the boss end has the outer end flat nick again.Have flat keyway in the middle of the positioning cylinder top, flat keyway is provided with the outer end flat nick is vertical.When positioning cylinder was installed in the dead eye of turbocharger intermediate, its boss can be located near the dead eye outer face.There is the bearing support of certain angle of inclination A to be packed on the base.Base is packed on the bench drill workbench.The intermediate of turbocharger is placed in above the bearing support.The plane cooperates installation with the outer end flat nick of positioning cylinder in being installed in dead eye on the bearing support.Definite method of bearing support angle of inclination A is: when inclined oil hole of air to be bored is in vertical position on the turbocharger intermediate bearing hole wall, one angle of inclination A is arranged between turbocharger intermediate axis and the vertical line, and this angle of inclination A also is the angle of inclination A of bearing support and vertical plane.The cylinder drill jig is one to have the structure of three stairsteppings, and cylinder drill jig bottom is a bluff body, the chip pocket that drill guide bore is arranged and communicate with pilot hole in the middle of the cylinder drill jig.When the cylinder drill jig is inserted in the intermediate oil-in, the assembling that is slidingly matched of three ladders of cylinder drill jig and three oil-in internal diameters of intermediate.The assembling that matches with flat keyway on the positioning cylinder of its bluff body.The bench drill drill bit be arranged on drill guide bore directly over and consistent with the drill guide bore direction.
Operation principle of the present utility model and process are: in the dead eye of the intermediate of at first positioning cylinder being packed into and make flat keyway up, in the intermediate oil-in of then the cylinder drill jig being packed into and the lower end bluff body is inlaid in the flat keyway of positioning cylinder.The bluff body of cylinder drill jig is lived in the keyway embedding, and the cylinder drill jig can not rotated.Again intermediate is placed on the bearing support, and the outer end flat nick of positioning cylinder is abutted against on the last plane of bearing support.Start bench drill the bench drill drill bit is descended, drill bit enters from the drill guide bore of cylinder drill jig and holes, and withdraws from drill bit after boring is finished.The cylinder drill jig is extracted, taken out positioning cylinder again, take off intermediate from base at last.Repeat the aforesaid operations program and can on another turbocharger intermediate, bore inclined oil hole of air.
The utility model has the advantages that provides a kind of drill jig that bores inclined oil hole of air in the intermediate oil-in that is drilled in common table.Bore inclined oil hole of air with this drill jig and have the advantage that technology is simple, cost is low, speed is fast, yield rate is high.
