To achieve the above object, the utility model uses following technical scheme:
A kind of arcwall face drilling-hole positioning device comprising bottom plate, bushing plate and two side connecting plates, the two sides of the bushing plate
By two side connecting plates respectively with the both ends screw locking of bottom plate, positioning chamber compatible with arcwall face, the positioning chamber are formed
One end is equipped with entrance, and the positioning chamber other end is equipped with two positioning pins for positioning arcwall face arc side, and the bushing plate is equipped with
More than one tapped through hole, tapped through hole internal screw thread are connected with the puller bolt for holding out against arcwall face, right on the bushing plate
The scheduled drill center of arcwall face is answered to be equipped with more than one compatible drill jig sleeve.
Preferably, the bushing plate is equipped with positioning plate, described positioning plate one end is connected on bushing plate, and positioning plate is another
One end two sides respectively with two positioning pin connections.
Preferably, described positioning plate one end is rotatably connected on bushing plate, the positioning plate other end is equipped with arc groove, arc
The fixing bolt rotated for limiting positioning plate relative to bushing plate is equipped in slot.
Preferably, the positioning plate is in T font.
Preferably, the drill jig sleeve is detachably connected with bushing plate.
The utility model uses above technical scheme, and when needing to drill to the arcwall face of workpiece, first passing through entrance will
Positioning chamber is slidably located in outside arcwall face, to be positioned using positioning chamber to two surfaces of arcwall face and side, then moves
Positioning chamber makes two positioning pins of the positioning chamber other end be connected to arcwall face arc side respectively, to utilize positioning pin to arcwall face
Arc side end is positioned, and then puller bolt is threaded in tapped through hole, so that the screw rod end end face of puller bolt is pushed up
Tight arcwall face, it is mobile to limit positioning chamber opposing arcuate face, so that the quick positioning of arcwall face is completed, it is last only to utilize correspondence
The drill jig sleeve of the scheduled drill center setting of arcwall face can precisely be drilled.The utility model is designed reasonably, structure is simple,
It is convenient to dismount, and boring positioning speed is fast, and precision is high, can preferably ensure machining accuracy.
