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。 Cutter bar guida nce partial tolera nces: ~ 。 Drill bit dia meter: 。附錄 附錄 1英文原文Vertical bearing seat drill hole aggregate machinetool design Author: Cnsaw article origin: Chinese sawing industry network 1 minute working procedure, decides the location type analysis This design vertica l bearing seat drill hole aggregate machinetool, its processes the ponents apply in the automobile extremely widely, should belong to the mass production project, therefore in design time should note to makes the processing to be simple as far as possible, but does not affect the processing quality. 2. Processing pla n formulation The division working procedure needs to consider to the production scale, the processing precision, uses the engine bed the character istic, the static load situation and so on. The division working procedure ma y have two kind of trends: The working procedure centralism and the working procedure are dispersible. The working procedure centralism disperses has its strong point respectively, in genera l, by enhances the productivity in the mass production prima rily, must widely use the multi knives, the single axle and multiple spind le is automa tic or the semia utoma tic engine bed, multiple spind le pla nertype milling machine, aggregate machinetool and so on, therefore adopts the working procedure centralism to be possible to obtain the prominent effect. In this design bearing seat drill hole aggregate machinetool very great degree causes various working procedures to concentrate as far as possible, the displa y aggregate machinetool mer it, at the same time causes each kind of error to reduce to the threshold. Because in this design processes in the ponents 10 holes the partial holes are away from too near, is not advantageous for the processing, therefore separates is two locations pletes, then carries on the ponents position transformation. Below the ma in location selects the pla n after the analysis: 1) loads and unloads, cla mps。 Cutting specifications: V= (10 ~ 18) m/Min, s=, rotationa l speed 350r/Min. B. Drills crosswise hole f16 with the highspeed steel drill bit (IV location) to process the dia meter: 16mm。 Leads the set of inside dia meter tolera nce: + ~ . hole processing during monly used working procedure the rema inder drills out the dia meter is 10 ~ 20, in dia meter working procedure rema inder for ( ~ ) mm。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 s
