Technical field the utility model relates to a kind of internal combustion engine vehicle supercharger spiral case digital control processing anchor clamps.
Background technology is in the internal combustion engine vehicle supercharger, spiral case is one of its important composition parts, its effect is to collect gas, and it is guided in the pressure inlet of engine, proceed gas compression processes simultaneously, after diffusion gas is come out, still be reduced to the air velocity of spiral case outlet, further improve the static pressure of gas with higher air velocity.The material of spiral case part is generally cast iron, adopts sand mold branch die cast to form usually.In existing spiral case process, often adopt machine tool to carry out.Such as by at vertical lathe, upright drill ， Shake arm drilling machine processes through multiple tracks circulation operation between the horizontal milling machine.The operation number of times of Workpiece circulation is various, needs manually centering repeatedly, and is time-consuming, and the critical process machining accuracy can not get guaranteeing.Particularly must not be greater than 0.06mm because of the concentricity requirement of the big small end face of spiral case workpiece both sides endoporus, big transverse plane must not be greater than 0.04mm with respect to the perpendicularity at center.In this technology of processing with machine tool, be divided into two procedures, clamping twice on different equipment, can be difficult to the required precision that reaches such.In addition, the inboard of spiral case is because design reasons causes structure more special, if the mode that adopts pressing plate to compress is processed, but the circular arc step that its supply plate compresses is very little, and pressing plate is unable to eat strength, tends to cause deflection in process, cause and to process, even workpiece is scrapped.
The summary of the invention technical problem to be solved in the utility model is to process on Digit Control Machine Tool, improve the machined speed of internal combustion engine vehicle supercharger spiral case and stably guarantee that crudy, the utility model provide a kind of internal combustion engine vehicle supercharger spiral case digital control processing anchor clamps.
Adopt Digit Control Machine Tool to process internal combustion engine vehicle supercharger spiral case compared with existing technology, precision and efficient all are significantly increased.This internal combustion engine vehicle supercharger spiral case numerical-control processing method, it is characterized in that: concrete processing can be divided into 6 procedures, they are respectively: (1) is rough turn little transverse plane and small end endoporus on NC vertical lathe, stay the finish turning surplus, (2) rough turn big transverse plane and big end endoporus on NC vertical lathe, stay the finish turning surplus, (3) the little transverse plane of milling on vertical machining centre, and bore thread Pilot hole and tapping on the little transverse plane, (4) the big transverse plane of finish turning on NC vertical lathe, big end opening facial plane and all endoporus, (5) on horizontal Machining centers the milling spiral case give vent to anger actinal surface and around facet, (6) on vertical machining centre, bore thread Pilot hole and tapping on the large end face.Wherein operation (4) is for guarantee to reach the critical process of above-mentioned required precision, designed booster spiral case digital control processing anchor clamps for this reason.
This booster spiral case digital control processing clamp structure is: base plate is fastened on the numerically controlled machine by screw and T type piece, at least 3 step supporters are uniform, and be fastened on the base plate by screw, it is characterized in that: disc circumference is provided with circle flange upwards, flange is provided with and the corresponding through hole in screwing hole, booster spiral case small end plane, disk upper surface is fastening by screw and the little transverse plane of booster spiral case, and lower disk surface is fastening by screw and supporter.Step supporter upper end is provided with the screw hole of fastening disk, is evenly equipped with the through hole that can insert screw on the step of lower end.Supporter can be uniform step cylinder, also can be the annular that whole periphery is provided with flange.Can there be one in the through hole that the disc circumference flange is provided with as locating hole.
The utility model has the advantages that: processing technology is reasonable in design, booster spiral case digital control processing clamp structure is simple, easy to operate, the booster spiral case is firmly secured on the workbench, make big transverse plane, big end opening facial plane and all endoporus are at this procedure once-forming, the concentricity requirement that has reached big small end face both sides endoporus fully must not be greater than 0.06mm, big transverse plane must not be greater than the specification requirement of 0.04mm with respect to the perpendicularity at center, and improved process velocity significantly, reduce labor intensity, improve product quality, thereby improved productivity ratio.
