e certain restra int measure, eliminates the object 6 degrees of freedom, then the object is located pletely. When for example discussion cuboid work piece, ma y arrange 3 not altogether lines in the bottom surface the obligator y points, arranges 2 obligator y points in the facade, arranges an obligator y point in the end surface, then the bottom surface obligator y point ma y limit X2, Y2, a Z23 degree of freedom, the facade obligator y point limits X1, a Z12 degree of freedom, the end surface obligator y point limits Y1 this degree of freedom, pletely has limited the cuboid work piece 6 degrees of freedom. C. Clamps the strength two essentia l factors, the direction and the action point cla mp the strength direction to be supposed to face locates the part, and causes to have cla mps the strength to be sma llest. The determination cla mps the point of force concurrence when the position should not destroy the loca lization. Clamps the point of force concurrence the position to be supposed to approach the processing spot as far as possible, by reduces the cutting force to circle cla mps the point of force concurrence the moment of force, prevented the work piece has the rotation or the 3 徐州 工 程 學 院 畢 業(yè) 設 計 (論文 )vibration in the processing process. Should guara ntee cla mps the distor tion not to affect the processing precision. Clamps the point of force concurrence number to be supposed to cause the work piece in the entire contact face the stress even, the juxtaposition meta morphose is sma ll. loca lization cla mps the plan the determination ponents belong to the hollow circular casting, the genera l loca lization part has V shape block, locates the sleeve to make the semicircle loca lization, if selects V shape block loca lization, as well as circled X, the Y rotation of axis degree of freedom in the Z axis traverse already eliminates, carried on the processing when the drill bit, circled the Z axis rotation the degree of freedom to be unable to eliminate actually, therefore located with V shape block the plan was inva lid. If the use semicircle loca lization, its result and with V shape block is same, all is unable to cause the work piece in to circle the Z axis in the direction to be stable, fina lly decides the use loca lization sleeve loca lization. Like chart 2 ringlike sleeves by H7/K6 or H7/The js6 excessively coordination loads the jig, after the ponents puts in the sleeve, in X, the Y direction degree of freedom elimination, at the same time uses the cla mp the method。Enable the cla mp using the ball head bolt tightly to suppress the work piece body. Like chart 3 shows, in under this cla mp function, along X rotation of axis X2, as well as and degree of freedom is all limited along Z rotation of axis Z2 along Z the axis direction Z1. Therefore in under this set of jig function, degree of freedom and so on X1, Y1, Z1, X1, Y1 is eliminated pletely, but under cla mp pressure function, between ponents and cutting tool formidable friction force, as well as in the processing process midd le axle directive force mutual counterbala nce, is also eliminated in the Z degree of freedom. When carries on to IV location, when processing crosswise hole, X1, Y1, the Z1 degree of freedom was eliminated, X2, the Y2 direction degree of freedom was also eliminated, in Z2 direction, because the cla mp function caused the work piece also to eliminate at the Z2 direction degree of freedom. 5 attacks the silk insta llment Attacks the system thread when the aggregate machinetool, according to is processed the ponents processing spot the distributed situation and the technologica l requirement and so on, monly used attacks the silk method to have 3 kinds: Uses attacks the silk power taper tap silk, uses attacks the silk insta llment to attack the silk and to use the activity to attack the silk template to attack the silk. In this design, the right half part pletes V, VI location processing. Electrica l machiner y only then power, therefore the synthesis considera tion selects attacks the silk insta llment to attack the silk. When puts in order the Taiwan engine bed or the engine bed some ple
