[0015] Example 1:
[0016] Such as figure 1 As shown, 1 is the base, 2 is the support frame, 3 is the bracket, 4 is the bearing I, 5 is the tailstock, 6 is the telescopic assembly, 7 is the bearing II, 8 is the cylinder (hydraulic or pneumatic), 9 is the crankshaft, 10 is the fan plate, 11 is the mandrel, and 12 is the journal.
[0017] The processing method of the original equipment: place both ends of the crankshaft 9 on the support frame, start the machine button, the claws clamp the crankshaft 9 and drive the crankshaft 9 to rotate, and the center hole at the right end of the crankshaft 9 is supported by a center to prevent shifting move. The automatic induction device of the machine tool automatically calculates the imbalance value, and the external tool drills the fan plate 10 to achieve the purpose of deweighting the fan plate 10 to ensure that the crankshaft imbalance value is within the specified range.
[0018] In the above-mentioned machining process, due to the limited...
