Eccentric workpiece when processing high precision lathe large quantities, can produce a special lathe eccentric clamping fixture and processing.
The workpiece is placed in the eccentric sleeve with an opening, clamping jaw self centering chuck; the workpiece in the eccentric shaft with flat key, for axial fastening by nut. Lathe This
form capable of processing multiple workpieces, top support, when necessary, can be used live.
Large eccentric workpiece can be used faceplate, curved plate and V-shaped block fixture.
Clamping in two between the top processing
The two top eccentric clamping the workpiece is a common fixture in the form of turning the eccentric shaft, crankshaft. Lathe eccentric shaft workpiece, as long as both ends can be drilled
center hole, there are heart-shaped chuck of the clamping position, and can use this form. The lathe of this Arrangement are: to ensure that the center hole of the corresponding machining
accuracy, and do not have rope, you can guarantee the eccentricity of the machining accuracy. Lathe operation of the processing steps are:
1) will bar or forgings maximum size of the diameter or the diameter of the maximum profile size car into the optical axis, both ends of the surface car level.
2) crossed. Underlined the procedure to find both ends of the center of the datum axis and the axis of the center of the eccentric surface, play the kind of red eye.
3) corresponding to the center hole drill press or boring machine drilling at both ends of each other.
4) The two top and heart-shaped clip mounted on the spindle or tailstock, step by step, segment ministries diameter and side cutting
