Fig. 1 is the structural representation of triplet exhaust manifold inlet flange drilling-hole positioning device in the present invention;
Fig. 2 is the structural representation of positioning clamping fixture in Fig. 1;
Fig. 3 is the structural representation of triplet exhaust manifold in the present invention.
Detailed description of the invention
Referring to Fig. 1, Fig. 2, triplet exhaust manifold inlet flange drilling-hole positioning device of the present invention, has a clamp body 1.According to the project organization of exhaust manifold, clamp body 1 is provided with the drill jig hole 3 corresponding with inlet flange connecting through hole on bushing plate 2.The bushing plate 2 of clamp body 1 is provided with 3 boring positioning clamping fixtures 4 and workpiece clamping mechanism, wherein 3 positioning clamping fixtures 4 are separately positioned on the position corresponding with the air flue air inlet of exhaust manifold two ends and centre, wherein the locating detent Y-axis of the positioning clamping fixture at two ends is arranged, the locating detent X axis of middle positioning clamping fixture is arranged, and is respectively used to X axis location and the Y-axis location of exhaust manifold air inlet.The plane of orientation 2-1 that the upper surface of bushing plate 2 is located as exhaust manifold datum level, for exhaust manifold positioning reference plane---the Z-axis direction location of inlet flange end face.
Described positioning clamping fixture 4 has the core carcass 11 of a T-shaped, and the top of this core carcass 11 is set with gland 12 by centre bolt 10, and core carcass 11 and gland 12 are slidably matched, and arrange holddown spring 13 between gland 12 and core carcass 11.The sidepiece of gland 12 arranges position-limitting pin 15, and the sidepiece of described core carcass 11 is provided with the limit sliding chutes 14 coordinated with described position-limitting pin 15, to prevent the rotation of core carcass 11.The bottom of core carcass 11 is provided with two-point locating pawl 9, the bushing plate 2 installing positioning clamping fixture 4 in correspondence is respectively arranged with 3 through holes, described locating detent installs with the through hole that described bushing plate is arranged and is connected, like this, by bolt 10, described positioning clamping fixture 4 is fixedly mounted on bushing plate 2, and makes described core carcass 11 be in elastic compression state all the time.Described workpiece clamping mechanism is by clamping fluid cylinder 7 and briquetting 5 forms, wherein, clamping fluid cylinder 7 is connected with the bushing plate of clamp body 1 by connecting pedestal 6, briquetting 5 is arranged on the telescopic end of clamping fluid cylinder 7 by connecting support plate 8, when carrying out inlet flange boring, by briquetting 5, exhaust manifold to be drilled can be pressed on clamp body 1.The arranged outside inclined-plane of described locating detent 9.To be easy to enter exhaust manifold air inlet, and closely cooperate with exhaust manifold air inlet under the pressure of described Compress Spring 13.Exhaust manifold inlet flange drilling-hole positioning device of the present invention is specially adapted to 4 cylinders or 6 Cylinder engine air flues are the Set and Positioning that circular exhaust manifold inlet flange is holed.
Composition graphs 1, Fig. 2 are referring to Fig. 3, exhaust manifold inlet flange drilling and positioning method of the present invention, that three air admission holes all adopt 2: 19,20,22,23,18,21 to locate with two air admission holes at exhaust manifold 16 two ends and a middle air admission hole for positioning datum.Concrete grammar is: be fixed on the workbench of radial drilling machine or machining center by described clamp body 1, again exhaust manifold 16 inlet flange 17 end face hole to be drilled is adjacent to down on the plane of orientation 2-1 of described bushing plate 2, realizes the Z reference axis location of exhaust manifold 16 with this.Meanwhile, make the air admission hole at exhaust manifold 16 two ends and middle air admission hole respectively with described locating detent 9 corresponding matching, each inlet flange 17 of exhaust manifold 16 is accurately located thus.Then, start described clamping fluid cylinder 7, by described briquetting 5, exhaust manifold 16 is compressed, described drill jig hole 3 can be utilized according to a conventional method to carry out the boring of inlet flange 17.
