Abstract
The utility model discloses a ball nut locking device which comprises a locking body and a locking drive air cylinder. The locking body is provided with a penetrating round through hole. A ball nut bushing is arranged in the round through hole. A deep groove ball bearing is installed between the outer side face of the ball nut bushing and the locking body. A ball nut is installed in the ball nut bushing. The ball nut is provided with a penetrating hole for a ball screw to penetrate through. A locking inclination pin is arranged above the ball nut bushing. The top of the ball nut bushing makes contact with the bottom face of the locking inclination pin. The locking drive air cylinder is arranged on one side of the locking body and connected with the locking inclination pin through a locking connection rod and can drive the locking inclination pin. The ball nut locking device can be fast switched between the locking state and the releasing state, and ensure that a work table can move or stop on a guide rail accurately.

Number in the figure explanation: locking body 1, locking drive cylinder 2, ball nut edge cover 3, deep-groove ball ball bearing 4, ball nut 5, locking gradient pin 6, locking connecting rod 7, locking force bearing point 8.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, ball nut locking device described in the utility model, comprises that locking body 1 and locking drive cylinder 2.
Wherein, described locking body 1 has the manhole running through, in described manhole, be provided with ball nut edge cover 3, between the outer side surface of ball nut edge cover 3 and locking body 1, deep-groove ball ball bearing 4 is installed, inside at ball nut edge cover 3 is provided with ball nut 5, and ball nut 5 has the penetration hole passing for ball screw; The top of described ball nut edge cover 3 is provided with locking gradient pin 6, and the top of ball nut edge cover 3 contacts with the bottom surface of locking gradient pin 6.
Described locking drives cylinder 2 to be arranged at a side of locking body 1, and locking drives cylinder 2 be connected with locking gradient pin 6 by locking connecting rod 7 and can drive locking gradient pin 6.
Described ball nut edge cover 3 tops are disc, and the bottom surface of locking gradient pin 6 is inclined-plane, and the top of described locking half round pin contacts and forms locking force bearing point 8 with the bottom surface of locking gradient pin 6.
Described locking gradient pin 6 is provided with opening with the side that is connected of locking connecting rod 7, and one end of locking connecting rod 7 is positioned at this opening, and the other end of locking connecting rod 7 is positioned at locking and drives cylinder 2.
Described locking body 1 drives cylinder 2 to be connected by integral structure with locking.
Working principle of the present utility model is as follows:
In the time that locking drives cylinder 2 to work, connected locking connecting rod 7 promotes locking gradient pin 6 and moves right, the suffered power of locking force bearing point 8 that the bottom surface of locking gradient pin 6 and ball nut edge cover 3 form increases, the power of its vertical direction also constantly increases, locking gradient pin 6 presses ball nut edge cover 3, ball nut edge cover 3 and inner ball nut 5 thereof cannot rotate, thereby realize the locking state to ball screw.
In the time that locking drives cylinder 2 to quit work, the suffered power of locking force bearing point 8 that the bottom surface of locking gradient pin 6 and ball nut edge cover 3 form disappears, and locking gradient pin 6 no longer presses ball nut edge cover 3, thereby realizes relaxation state.
Coupling mechanism force of the present utility model can reach 11.5 times that locking drives cylinder 2 to exert oneself, and under same cylinder is exerted oneself, its coupling mechanism force has substantially exceeded the coupling mechanism force of existing apparatus.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
