Machine processing technology requirements
The parts to be machined mainly include the end stops, end faces, inner circle, foot plane, foot hole, fixed end cover, outlet box and lifting bolts. For the separate frame, it is also necessary to process the split face, the split screw hole and the pin hole. The technical requirements that should be met during machining of the base can be summarized as follows.
● The dimensional accuracy and roughness of each processing part should conform to the drawings. The accuracy and roughness requirements of the two end stops and the inner circle are both high, and the center high dimensional accuracy is also accurate.
● The geometrical tolerances of each processing surface shall comply with the drawings. The coaxiality between the two ends of the stop and the inner circle, and the end face circular jump of the two ends facing the axis line are the key to the machining of the base. Special emphasis: if the geometric tolerance is not specified, the maximum and minimum values should be within the dimensional tolerance; the foot plane should be parallel to the axis.
● The distance between the foot hole and the center line of the base should be symmetrical and meet the specified tolerances.
● After the magnetic machine base is machined, the thickness of each part of the yoke should be uniform. The poles of the poles should be equal and their position must comply with the drawings.
●The split surface of the split type base requires stable joint and reliable positioning, and can still meet the original requirements when reassembled and reassembled.
