Summary of the invention
The present invention for solve in known technology the technical problem that exists and provide simple, easy to use safe, the functional and a kind of electric actuator that can operate at any time of a kind of structure manually with electronic transformational structure.
The technological scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of manual and electronic transformational structure of electric actuator, comprise hand seat, hand seat one end is provided with needle bearing; Also comprise the hand wheel shaft running through needle bearing, hand wheel shaft one end is connected with handwheel; Setting sleeve is provided with in hand seat, be provided with in the end of electric actuator worm screw and drive termination, the axis collinear of worm screw and hand wheel shaft, described setting sleeve one end is fixedly connected on hand wheel shaft end, the other end has the hole that the driving termination of worm screw can be made to pass, setting sleeve is fixed with positioning plate, this positioning plate is positioned on the exterior edge face that setting sleeve is connected with hand wheel shaft, is provided with spring between the end face of this end face and hand seat; In hand seat, being also provided with the sensitive switch corresponding with positioning plate and the fixing device for limiting hand wheel shaft axial position, hand wheel shaft having the groove matched with fixing device.
Advantage of the present invention and good effect are: by the design of this kind of manual and electronic transformational structure of electric actuator, the personal safety of operator under electronic executing state can be ensured, handwheel can not rotate along with worm screw, and operator can in officely what is the need for when wanting manually-operable, can manual switch be carried out without the need to power-off, infringement can not be produced to motor, gear and some other part.
Preferably: described fixing device is ball limit stoper, the stage clip comprising socket head screw, ball and be placed between ball and socket head screw.
Preferably: described setting sleeve is fixedly connected on hand wheel shaft end by flat key and shaft retaining ring.
Accompanying drawing explanation
Fig. 1 is the structural representation under motoring condition of the present invention;
Fig. 2 is the structural representation under manual mode of the present invention.
In figure: 1, worm screw; 2, hand seat; 3, setting sleeve; 4, positioning plate; 5, spring; 6, sensitive switch; 7, needle bearing; 8, socket head screw; 9, stage clip; 10, ball; 11, hand wheel shaft; 12, shaft retaining ring; 13, flat key.
Embodiment
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
See Fig. 1, the invention provides the manual of a kind of electric actuator and electronic transformational structure, comprise hand seat 2, hand seat 2 one end is provided with needle bearing 7, hand wheel shaft 11 is connected with handwheel and passes needle bearing 7.
In the present embodiment, setting sleeve 3 is provided with in hand seat 2, be provided with in the end of electric actuator worm screw 1 and drive termination, worm screw 1 and hand wheel shaft 11 axis collinear, described setting sleeve 3 one end is fixedly connected on hand wheel shaft 11 end by flat key 13 and shaft retaining ring 12, setting sleeve 3 the other end has and worm screw 1 can be made to drive termination to pass and the hole producing contact, setting sleeve 3 is fixed with positioning plate 4, this positioning plate 4 is positioned on the exterior edge face that setting sleeve 3 is connected with hand wheel shaft 11, and this end face is connected with the end face of hand seat 2 by spring 5.
Two sensitive switches 6 corresponding with positioning plate 4 and the fixing device for limiting hand wheel shaft 11 axial position is also provided with in hand seat 2, hand wheel shaft 11 has the groove matched with fixing device, fixing for hand wheel shaft 11 axial position under manual and motoring condition.
Described ball limit stoper is arranged on hand seat 2, the stage clip 9 comprising socket head screw 8, ball 10 and be placed between ball 10 and socket head screw 8.
This kind of electric actuator electric and manual manipulation regulates the specific operation process of transformational structure as follows:
See Fig. 1, be electric control state, handwheel keeps the state pulled out, and fixing device blocks draw-in groove during Electronic control on hand wheel shaft 11, realizes the fixing of hand wheel shaft 11 axial position.Positioning plate 4 now on setting sleeve 3 contacts with the sensitive switch 6 of hand seat 2 internal fixtion, realize energising, the square hole now setting sleeve 3 the other end had be able to entangle the driving termination of worm screw 1 and produce the contact on certain length with its side, realize Electronic control worm screw 1, now hand wheel shaft 11 is separated with worm screw 1, keeps handwheel motionless when worm screw 1 is rotated.
