Hand wheel driving device and electric actuating mechanism

Abstract

The invention discloses a hand wheel driving device and an electric actuating mechanism. The hand wheel driving device comprises a hand wheel, a hand wheel shaft connected to the rotating axis of the hand wheel and a driving shaft coaxial with the hand wheel shaft, a shaft sleeve is arranged at the end of the hand wheel shaft, and a hand wheel connecting shaft matched with the shaft sleeve is arranged at the end, opposite to the shaft sleeve, of the driving shaft; the shaft sleeve is provided with a pin which is radially arranged and extends into the shaft sleeve; a notch matched with the pin is formed in the outer surface of the hand wheel connecting shaft and comprises a pin entering groove, a first transition groove, a driving groove, a second transition groove and a pin disengaging groove which are sequentially connected. When the hand wheel drives the driving shaft to rotate, the pin is connected with the driving groove. The pin entering groove, the first transition groove, the driving groove, the second transition groove and the pin disengaging groove are sequentially connected, the first transition groove extends to the inlet of the driving groove, the outlet of the driving groove extends to the inlet of the second transition groove, and the outlet of the second transition groove extends to the pin disengaging groove, so that operation is easy, and combination and disengaging are rapid and efficient.

Description

technical field [0001] The invention relates to the technical field of electric actuators, in particular to a handwheel drive device and an electric actuator. Background technique [0002] At present, the common electric actuators are commonly operated in two ways. One is to push and turn the handwheel to work, which is very inconvenient and laborious; the other is to use switching The way that the pin restricts the position of the manual shaft, in manual operation, it is necessary to pull up the pin first, push the handwheel shaft in place, and then press down the pin, and then the manual operation can be performed, which is complicated in structure and complicated in operation. This patent provides a novel manual mechanism of an electric actuator, which solves the above-mentioned problems, and at the same time has a simple structure and convenient operation. SUMMARY OF THE INVENTION [0003] In order to solve the deficiencies in the prior art, the present invention prov...
