This
Invention
Walking-beam counterweight
Can be as the auxiliary adjustment mode of crank balance, the balancing operation of crankshaft balance weight is comparatively laborious, the longest, it is impossible to realize adjusting in real time, and the precision adjusted is the lowest.Walking-beam counterweight can compare fine adjustment, and does not has big workload.
The push-pull electromagnet of the present invention is a kind of both economical reliable calutron, and low price, environment resistant good, capacity of resisting disturbance is strong.
This
Invention host computer calculates balance deviation amount and adjustment direction according to the electrical quantity information collected, and first sends instruction to the A.C. contactor connecting push-pull electromagnet, makes balance weight unlock to electric magnet energising.Simultaneously for preventing owing to balance weight gravity pressure causes electric magnet to unlock, host computer sends instruction to servo controller, controls motor frequent rotating within 5 seconds, to release gravity pressure, helps balance weight to unlock.When push-pull electromagnet successfully resets (after i.e. unlocking successfully), and it will send signal to host computer.Host computer could send operating instruction to servo controller after only having received signal, drives motor to run by required direction, is balanced adjusting.Ready to balance block is adjusted to specific bit and postpones; first host computer sends power-off signal to A.C. contactor; push-pull electromagnet push rod is released under the action of the spring; the band dynamic balance weight of motor continuation simultaneously moves; after electromagnet push-rod enters circular lock hole, push-pull electromagnet sends the successful signal of locking to host computer, and after receiving this signal, host computer sends halt instruction to servo controller; balance adjustment is complete, and regulation is accurate, regulating effect is good.
