Description
Technical field
The present invention relates to a kind of drilling tool, more particularly to a kind of connecting rod positioning drill jig.
Background technology
Connecting rod is connection piston and bent axle, and active force suffered by piston is transmitted into bent axle, and the reciprocating motion of piston is changed
For a kind of rod member of the rotary motion of bent axle.Connecting rod is the part in connection rod set, connection rod set by gonnecting rod body, connecting rod cap,
Lining of connecting rod small end, big end bearing shell and connecting-rod bolts（Or screw）Deng composition；Gonnecting rod body is made up of three parts, with piston pin
The part of connection claims small end of connecting rod；The part being connected with bent axle claims big end, and the bar portion for connecting microcephaly and major part claims connection-rod
Body；Because connecting rod requires lighting, so while connecting rod strength is ensured, it is I-shaped by the way that connecting rod shank is set to,
So as to reduce quality.Because big end needs to be connected with connecting rod cap, so big end needs to bore two bolt connections
Hole；So needing to carry out positioning clamping to connecting rod；Present clamping tool is to carry out positioning clamping, two to connecting rod by two axles
Individual axle coordinates with the semicircle cambered surface of the connecting hole of small end of connecting rod and big end respectively, and one of axle fix another axle can
To slide, and the axle that can be slided by screw-driven just can be clamped to connecting rod；But this clamping means is only from the perpendicular of connecting rod
To being clamped, increased so being shaken in drilling, and in order to ensure the located lateral of connecting rod, it is necessary to it is that connecting rod is adjacent to fixed
In the reference plane of position, so being generally all the side for tapping connecting rod, so as to easily exist in order that connecting rod is close on positioning reference plane
Left a trace on connecting rod.
The content of the invention
The invention is intended to provide a kind of connecting rod positioning drill jig, to solve orientation problem during drilling holes on connecting rods.
The base case connecting rod positioning drill jig of the present invention, including frame, clamping section and bore portion；Clamping section and bore portion are equal
In frame, bore portion includes two drill bits；Characterized in that, the clamping section includes pedestal, pressing plate, clamping jaw, screw rod
And locating piece；The pilot hole set on vertical guide rod, the pressing plate corresponding to guide rod is fixedly connected with the pedestal,
Pilot hole coordinates with guide rod gap, and pressing plate is slidably connected on pedestal；The clamping jaw is V-shaped, at the flex point of clamping jaw and institute
State pedestal to be hinged, the two ends of clamping jaw are divided into bare terminal end and force side by clamping jaw using flex point as boundary, and the force side of clamping jaw is located at institute
The lower section of pressing plate is stated, and the right side of the pressing plate has a bar v notch v and is located at two drill bits of bar v notch v both sides respectively
By hole, the bare terminal end of clamping jaw is paid from the bar v notch v of pressing plate；The drill bit on the pedestal below hole by being additionally provided with one
Individual semicircular projection, drill bit passes through the top in hole for bore portion, and drill bit is respectively aligned to two drill bits and passes through hole；The pressing plate
Be provided centrally with a bar hole, the screw rod passes through this bar hole, and the lower end of screw rod and the force side of the clamping jaw are hinged,
The upper end of screw rod is provided with screw thread, and has screwed nut；The locating piece is relative with the bare terminal end of the clamping jaw, and locating piece is slided
It is dynamic to be connected on pedestal.
In this base case, it plays a part of clamping and positioning to workpiece for clamping section, and bore portion plays the work of drilling
With.The locating piece of clamping section is horizontal positioning datum, and semi-circular projection is vertical positioning datum, while semicircle convex
The lower end that block is also prevented from connecting rod is swung；The bar v notch v opened up on the right side of pressing plate so that the right side of pressing plate is in fork-shaped, a side
Face can be such that the bare terminal end of clamping jaw is stretched out from bar shaped indentation, there, so that clamp linkage shaft, and clamping jaw is fastened on connecting rod shank
In groove, so as to prevent small end from swinging；Bar v notch v on the right side of another aspect pressing plate, can make it that compression connecting rod is big
Connecting rod shank can be crossed during head.Locating piece is slidably connected with pedestal, more facilitates mainly for laying workpiece or taking out workpiece,
From without pressing plate will be dismantled when laying workpiece every time or taking out workpiece.
By screwing the nut on screw rod, then the distance of the force side of pressing plate and clamping jaw can be gradually reduced, due to clamping jaw
Screw rod can be driven to produce certain transverse shifting during rotation, so the hole of screw rod through pressing plate is set to bar hole, in pressing plate and
While the distance of the force side of clamping jaw is gradually reduced, the downward workpiece pressing of pressing plate, the bare terminal end of clamping jaw is applied from left side to workpiece
Power, by Work-sheet pressing on locating piece；Comprehensive positioning of workpiece is just completed with this.
Preferred scheme one, as the further optimization to base case, the guide rod is provided with three altogether, and guide rod is welded
It is connected on the pedestal, guide rod is located at three summits of isosceles triangle respectively；This optimization can make peace of the pressing plate on pedestal
Fill more stable.
Preferred scheme two, as the further optimization to base case, on the guide rod between the pressing plate and pedestal, institute
State and be arranged with return spring on the screw rod between pressing plate and the force side of clamping jaw；This optimization can be in the nut on unclamping screw rod
Afterwards, pressing plate and clamping jaw can from workpiece appliance for releasing single.
Preferred scheme three, as the further optimization to base case, force surface from the bare terminal end of the clamping jaw to workpiece
Clamping face for the clamping face of clamping jaw, and clamping jaw is set to cambered surface；Because clamping jaw is lever construction, so when clamping jaw clamps workpiece
When, clamping jaw can produce certain rotation, in order that clamping jaw can preferably clamp workpiece, so the clamping face of clamping jaw is set into arc
Face.
