Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1:
A kind of rotation-preventing mechanism, as shown in Figs 1-4, including fixing seat 1, anti-rotation shaft 2 and power take-off mechanism 3.It is wherein solid
Reservation 1 is for being fixed at gearbox assembly line locking nut screwing station.Fixing seat 1 is fixedly arranged above anti-rotary seat 4, anti-rotation shaft
2 are located at 4 inside of anti-rotary seat and are slidably connected with anti-rotary seat 4.In order to guarantee that anti-rotation shaft only moves axially in anti-rotary seat, keep away
Exempt from anti-rotation shaft to rotate in anti-rotary seat, in the present embodiment, be connected between anti-rotary seat 4 and anti-rotation shaft 2 by spline.Using flower
The mode of key connection is it is possible to prevente effectively from anti-rotation shaft rotates in anti-rotary seat.
2 top of anti-rotation shaft is fixed with the anti-rotary head 5 for holding output shaft tightly.In order to embrace anti-rotary head effectively with output shaft
Tightly, it is internal spline inside anti-rotary head 5, is external splines outside output shaft, when the outer flower in the internal spline and output shaft in anti-rotary head
When key teeth is cooperatively connected, anti-rotary head and output shaft are held tightly.2 internal slide of anti-rotation shaft connects a gag lever post 6.Specifically, anti-rotation shaft 2
It is internally provided with through slot 2.1, includes a positive stop lug boss 2.2 in through slot 2.1, limit bar part is located in through slot 2.1, and gag lever post
6 end is abutted with positive stop lug boss 2.2.Another part of gag lever post 6 extends to below fixing seat, the bottom end of gag lever post 6 and fixed
Position plate 7 is fixed.6 outer cover of gag lever post is equipped with spring 8, is fixed with gasket 9 in gag lever post 6 at the bottom position of gag lever post,
One end of spring 8 is abutted with gasket 9.
Power take-off mechanism 3 is fixed in fixing seat 1.In the present embodiment, power take-off mechanism 3 be cylinder, cylinder it is defeated
Shaft connects a floating junction 10 after passing through fixing seat 1, and floating junction 10 is connect by briquetting 19 with positioning plate 7.
When rotation-preventing mechanism needs to hold output shaft tightly, anti-rotary head is docked in advance with output shaft first.If interior in anti-rotary head
When on spline is not corresponding with the interior external tooth in the external splines in output shaft, anti-rotary head is squeezed by output shaft, anti-rotary head and anti-
Shaft is compressed along anti-rotary seat slide downward, spring, and output shaft rotates under the action of screwing force, so that anti-rotary head
In internal spline it is corresponding with the interior external tooth in the external splines in output shaft on, at this time since spring gives anti-rotation shaft active force, anti-rotation
The anti-rotary head on axis top can be set on the output shaft, and then hold output shaft tightly, prevent output shaft from rotating.
In order to realize that automation control rotation-preventing mechanism operates, in the present embodiment, first switch bracket is fixed in fixing seat 1
11, it is fixed with anti-rotary head in first switch bracket 11 and approaches switch 13 in place close to switch 12 and positioning plate in place.Anti- rotary head
It is connect in place close to switch 13 with external controller close to switch 12 and positioning plate in place, controller is electrically connected with cylinder.
The bottom of anti-rotation shaft 2 is fixed with induction bracket 14.Induction bracket 14 include a L-type induction part 14.1, L-type induction part 14.1 along
Gag lever post 6 extends downwardly.When positioning plate 7 reaches positioning plate in place close at 13 position of switch, positioning plate is in place close to switch 13
Sending signal in place, to controller, controller sends a signal to cylinder 3 in turn, and cylinder drives positioning plate stopping to move upwards.
When the L-type induction part 14.1 in induction bracket reaches anti-rotary head in place close at 12 position of switch, anti-rotary head is in place close to switch
12 will be sent to controller by signal in place, and controller shows anti-rotary head in place by display screen, i.e., output shaft is held in anti-rotary head tightly.
In order to which automation control rotation-preventing mechanism is in home position in a non-operative state, in the present embodiment, in fixing seat 1
Be slidably connected an optical axis 15, and induction block 16 is fixed on optical axis 15, and 15 bottom end of optical axis and positioning plate 7 are fixed.It is solid in fixing seat 1
Surely there is second switch bracket 17, close switch 18 in situ is fixed in second switch bracket 17, it is in situ close to switch 18 and external
Controller connection.It is in situ close to the transmission signals in situ of switch 18 when induction block 16 reaches at close 18 position of switch in situ
To controller, controller sends a signal to cylinder in turn, and cylinder drives positioning plate stopping to move downward.
The mode of automation control is specific as follows: when rotation-preventing mechanism needs to hold output shaft tightly, controller controls gas first
Cylinder moves up positioning plate, and positioning plate drives gag lever post, anti-rotation shaft and anti-rotary head to move up, and determines when positioning plate reaches
In place close to when switching, controller control cylinder stops operating position plate.If the outer flower in the internal spline and output shaft in anti-rotary head
When on interior external tooth in key is corresponding, anti-rotary head is squeezed by output shaft, anti-rotary head and anti-rotation shaft along anti-rotary seat slide downward,
Spring is compressed, and output shaft rotates under the action of screwing force, so that outer in the internal spline and output shaft in anti-rotary head
Interior external tooth in spline corresponds to, and the L-type induction part in induction bracket reaches anti-rotary head in place close to switch at this time, and anti-rotary head is arrived
Position shows that output shaft is held in anti-rotary head tightly to controller signals close to switch.After completing operation, controller, which controls cylinder and drives, to be determined
Position plate moves downward, and when the induction block in optical axis reaches close switch in situ, controller control cylinder stops operating, and shows
Rotation-preventing mechanism returns to original position.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
