Description
Technical field
This utility model relates to a kind of drilling tool, particularly relates to a kind of connecting rod location drill jig.
Background technology
Connecting rod is for connecting piston and bent axle, and active force suffered by piston is passed to bent axle, and the reciprocating motion of piston is changed into a kind of rod member of the rotary motion of bent axle.Connecting rod is the part in connection rod set, and connection rod set is made up of gonnecting rod body, connecting rod cap, lining of connecting rod small end, big end bearing shell and connecting-rod bolts (or screw) etc.；Gonnecting rod body is made up of three parts, and the part being connected with piston pin claims small end of connecting rod；The part being connected with bent axle claims big end, and the bar portion connecting microcephaly and major part claims connecting rod shank；Owing to connecting rod is desirable that lighting, thus while ensureing connecting rod strength, I-shaped by connecting rod shank is set to, thus reducing quality.Owing to big end needs to be connected with connecting rod cap, so big end needs to bore two bolt connecting holes；So needing connecting rod is positioned clamping；Present clamping tool is, by two axles, connecting rod is positioned clamping, two axles coordinate with the semicircle cambered surface of the connecting hole of small end of connecting rod and big end respectively, and one of them axle fixes another axle and can slide, and connecting rod just can be clamped by the axle that can be slided by screw-driven；But these clamping means only being vertically clamped from connecting rod, so vibrations strengthen when boring, and in order to ensure the located lateral of connecting rod, it is accomplished by being that connecting rod is adjacent on positioning reference plane, so in order to make connecting rod be close on positioning reference plane, it is generally all the side knocking connecting rod, thus very easily leaving a trace on connecting rod.
Utility model content
This utility model is intended to provide a kind of connecting rod location drill jig, to solve orientation problem during drilling holes on connecting rods.
Base case connecting rod of the present utility model location drill jig, including frame, clamping section and bore portion；Clamping section and bore portion are installed in frame, and bore portion includes two drill bits；It is characterized in that, described clamping section includes pedestal, pressing plate, jaw, screw rod and locating piece；Described pedestal is fixedly connected with vertical guide post, described pressing plate arranges the pilot hole corresponding to guide post, pilot hole and guide post matched in clearance, pressing plate is slidably connected on pedestal；Described jaw is V-shaped, the flex point place of jaw is hinged with described pedestal, jaw is with flex point for boundary, the two ends of jaw are divided into bare terminal end and force side, and the force side of jaw is positioned at the lower section of described pressing plate, and the right side of described pressing plate has a bar v notch v and lays respectively at two drill bits of bar v notch v both sides by hole, the bare terminal end of jaw is paid from the bar v notch v of pressing plate；Described drill bit is by being additionally provided with a semicircular projection on the pedestal below hole, and drill bit is arranged above bore portion by hole, and drill bit is respectively aligned to two drill bits and passes through hole；Described pressing plate be provided centrally with a bar hole, described screw rod is through this bar hole, and the lower end of screw rod is hinged with the force side of described jaw, and the upper end of screw rod is provided with screw thread, and has screwed nut；Described locating piece is relative with the bare terminal end of described jaw, and locating piece is slidably connected on pedestal.
In this base case, clamping section its workpiece is played the effect of clamping and positioning, and bore portion plays the effect of boring.The locating piece of clamping section is horizontal positioning datum, and semi-circular projection is vertical positioning datum, and semicircle projection is also prevented from the lower end swing of connecting rod simultaneously；The bar v notch v that the right side of pressing plate is offered so that the right side of pressing plate is fork-shaped, on the one hand can make the bare terminal end of jaw stretch out from bar shaped indentation, there, thus clamp linkage shaft, and jaw is fastened in the groove of connecting rod shank, such that it is able to prevent small end from swinging；Bar v notch v on the right side of pressing plate on the other hand, it is possible to connecting rod shank can be crossed when making to compress big end.Locating piece and pedestal are slidably connected, convenient mainly for laying workpiece or taking-up workpiece, will dismantle pressing plate from without when laying workpiece or taking out workpiece every time.
By screwing the nut on screw rod, the distance that then can make the force side of pressing plate and jaw is gradually reduced, owing to screw rod can be driven when jaw rotates to produce certain transverse shifting, so the hole of screw rod traverse pressing plate is set to bar hole, the distance of pressing plate and the force side of jaw is diminishing while, pressing plate is pressed downward against clamping of workpieces, and the bare terminal end of jaw exerts a force from left side to workpiece, by Work-sheet pressing on locating piece；Just comprehensive location of workpiece is completed with this.
Preferred version one, as the further optimization to base case, described guide post is provided with three altogether, and guide post is welded on described pedestal, and guide post lays respectively at three summits of isosceles triangle；This optimization can make pressing plate installation on pedestal more stable.
Preferred version two, as the further optimization to base case, the screw rod on the guide post between described pressing plate and pedestal, between described pressing plate and the force side of jaw is all arranged with return spring；This optimization can after the nut unclamped on screw rod, and pressing plate and jaw can from appliance for releasing singles workpiece.
Preferred version three, as the further optimization to base case, the bare terminal end of described jaw is the clamping face of jaw to the force surface of workpiece, and the clamping face of jaw is set to cambered surface；Owing to jaw is lever construction, so when jaw clamps workpiece, jaw can produce certain rotation, in order to make jaw can better clamp workpiece, so the clamping face of jaw is set to cambered surface.
