Abstract
The utility model discloses a hand wheel rotating and switching device of an electric actuating mechanism, which comprises a hand wheel, a pin shaft, a worm screw, a clutch, a roll ball and a spring,wherein the hand wheel is fixedly connected with the clutch, and the pin shaft is fixed on the worm screw and disengaged from or locked with the clutch. The utility model has the benefits that becausethe claw clutch is disengaged from or locked with the pin shaft fixedly connected to the worm screw, the manual/automatic switching of the electric actuating mechanism becomes simpler, and the operation becomes more convenient.
Description
Technical field
The utility model relates to a kind of electric actuator, and the handwheel that particularly relates to a kind of electric actuator rotates COMM communication.
Background technique
Electronic and the manual switching device of existing electric actuator adopts hand automatic switchover clutch, when each manual and electronic switching, need artificial promotion handwheel or pull out handwheel, handwheel sets back again when openhanded opening, and the handwheel of this structure rotates COMM communication and causes the operator to use inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the shortcoming of prior art, the handwheel rotation COMM communication that provides a kind of actuator handwheel when electronic or manually-operable can be fixed on the relevant position.
The technological scheme that the utility model adopted is: the handwheel of electric actuator rotates COMM communication, comprises handwheel, bearing pin, worm screw, clutch, ball and spring; Described handwheel is fixedlyed connected with clutch, and described bearing pin is fixed on the worm screw, and with throw-out-of clutch or pinning.
Described clutch is a claw clutch; The outside of described clutch is provided with groove, and described ball and spring are arranged in one of them groove.
The beneficial effects of the utility model are: since claw clutch be fixedly connected on bearing pin on the worm screw and break away from or pin, make electric actuator manual automatically switch simple, more convenient to operate.
Description of drawings
Fig. 1 is the structural representation of the utility model handwheel idle running when electronic;
Fig. 2 be the utility model when manual handwheel drive the structural representation that worm screw is rotated.
Among the figure:
1. handwheel 2. bearing pins 3. worm screws 4. clutches
5. ball 6. springs
Embodiment
Below, with embodiment the utility model is further described in detail in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the utility model handwheel idle running when electronic; Fig. 2 be the utility model when manual handwheel drive the structural representation that worm screw is rotated.
As depicted in figs. 1 and 2, the handwheel of the utility model electric actuator rotates COMM communication, comprises handwheel 1, bearing pin 2, worm screw 3, clutch 4, ball 5 and spring 6; Described clutch 4 is a claw clutch; The outside of described clutch is provided with groove 41, and described ball 5 and spring 6 are arranged in one of them groove 41; Described handwheel 1 is fixedlyed connected with clutch 4, and described bearing pin 2 is fixed on the worm screw 3, and throws off or pinning with clutch 4.
The working principle that the handwheel of the utility model electric actuator rotates COMM communication is: as shown in Figure 1, when actuator is in electronic working state, handwheel is located by ball after being pushed into casing together with the clutch on it of being connected, handwheel is fixed on electronic working state, handwheel does not participate in rotating, at this moment, claw clutch breaks away from the bearing pin that is connected on the worm screw, worm screw idle running.As shown in Figure 2, when actuator was in the manual work state, handwheel was located by ball after being drawn out casing together with the clutch on it of being connected, and claw clutch pins the bearing pin that is connected on the worm screw, handwheel is fixed on the manual work state, rotates handwheel and drives the worm screw rotation by bearing pin.Since claw clutch be fixedly connected on bearing pin on the worm screw and break away from or pin, make electric actuator manual automatically switch simple, more convenient to operate.
Claims (2)
