Description
Technical field
The present invention relates to a kind of drilling tool, particularly relate to a kind of connecting rod location drill jig.
Background technology
Active force suffered by piston for connecting piston and bent axle, and is passed to bent axle by connecting rod, 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 be connected with piston pin claims small end of connecting rod; The part be connected with bent axle claims big end, and the bar portion connecting microcephaly and major part claims connecting rod shank; Because connecting rod all requires lighting, so while guarantee connecting rod strength, I-shaped by connecting rod shank is set to, thus reduce quality.Because big end needs to be connected with connecting rod cap, so big end needs brill two bolt connecting holes; So need to position clamping to connecting rod; Present clamping tool positions clamping by two axles to connecting rod, two axles coordinate with the connecting hole of small end of connecting rod and the semicircle cambered surface of big end respectively, and one of them axle is fixed another axle and can be slided, and just can be clamped connecting rod by the axle that screw-driven can slide; But these clamping means vertically clamping only from connecting rod, so vibrations strengthen when holing, and in order to ensure the located lateral of connecting rod, just need to be that connecting rod is adjacent on positioning reference plane, so in order to make connecting rod be close on positioning reference plane, usually be all the side of knocking connecting rod, thus very easily leave a trace on connecting rod.
Summary of the invention
The invention is intended to provide a kind of connecting rod to locate drill jig, to solve orientation problem during drilling holes on connecting rods.
Base case connecting rod location of the present invention drill jig, comprises frame, clamping section and bore portion; Clamping section and bore portion are installed in frame, and bore portion comprises two drill bits; It is characterized in that, described clamping section comprises pedestal, pressing plate, jaw, screw rod and locating piece; Described pedestal is fixedly connected with vertical guide post, and described pressing plate is arranged the pilot hole corresponding to guide post, pilot hole and guide post matched in clearance, be slidably connected at pressing plate on pedestal; Described jaw is V-shaped, flex point place and the described pedestal of jaw are hinged, jaw take flex point as 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 below of described briquetting, and the right side of described pressing plate has a bar v notch v and lay respectively at two drill bit passing hole of bar v notch v both sides, the bare terminal end of jaw is paid from the bar v notch v of pressing plate; Pedestal below described drill bit passing hole is also provided with a semicircular projection, the top of drill bit passing hole is bore portion, and drill bit aims at two drill bit passing hole respectively; The center of described pressing plate is provided with a bar hole, and described screw rod is through this bar hole, and the force side of the lower end of screw rod and described jaw is hinged, 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 to 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 can also prevent the lower end of connecting rod from swinging simultaneously; The bar v notch v that the right side of pressing plate is offered, makes the right side of pressing plate be fork-shaped, the bare terminal end of jaw can be made to stretch out from bar shaped indentation, there on the one hand, thus clamping connecting rod shank, and jaw is fastened in the groove of connecting rod shank, thus can prevent small end from swinging; Bar v notch v on the other hand on the right side of pressing plate, can make can cross connecting rod shank when compressing big end.Locating piece and pedestal are slidably connected, convenient mainly for laying workpiece or taking out workpiece, thus all need not will dismantle pressing plate when laying workpiece or take out workpiece at every turn.
By screwing the nut on screw rod, the distance of the force side of pressing plate and jaw then can be made to reduce gradually, certain transverse shifting is produced due to screw rod can be driven when jaw rotates, so the hole that screw rod passes pressing plate is set to bar hole, the distance of the force side of pressing plate and jaw is diminishing while, the downward workpiece pressing of pressing plate, 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 the installation of pressing plate 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 unclamping the nut 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; Because jaw is lever construction, so when jaw clamping work pieces, jaw can produce certain rotation, in order to make jaw can better clamping work pieces, so the clamping face of jaw be set to cambered surface.
