Vertical bearing seat drill hole aggregate machine-tool design
Author: Cnsaw article origin: Chinese sawing industry network
1 minute working procedure, decides the location
1.Production type analysis
This design vertica l bearing seat drill hole aggregate machine-tool, its processes the components 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 ner-type milling machine, aggregate machine-tool 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 machine-tool very great degree causes various working procedures to concentrate as far as possible, the displa y aggregate machine-tool mer it, at the same time causes each kind of error to reduce to the threshold.
Because in this design processes in the components 10 holes the partial holes are away from too near, is not advantageous for the processing, therefore separates is two locations completes, then carries on the components position transformation.
Below the ma in location selects the pla n after the analysis: 1) loads and unloads, cla mps; 2) drills 7 holes f13.5; 3) drills 3 holes is f14, drills 2 threads bottom holes f14, Kong Haowei 8, 9; 4) drills crosswise hole f14; 5) expands articulation 7 holes f14.5; 6) attacks the silk.
2 compound cutting tools cutting specificationses computation
1.Cutting specifications character istic
The aggregate machine-tool norma l work and reasonably selects the cutting specifications, namely the determination reasonable cutting speed and the work enters to the quantity has the
very big relations. The cutting specifications elects the inappropriateness, can cause the aggregate machine-tool to reduce stops the loss, enhances the production efficiency, lengthens the cutting tool life, improves the processing quality.
2.Leads a set of design
