Abstract
The utility model relates to a rotation prevention device of a servo electric cylinder. The rotation prevention device comprises the servo electric cylinder which consists of power tubes, ball screws, ball nuts, reverse rotation prevention blocks, outer rectangular tubes, set screws, a servo motor and a synchronous belt box, wherein, four symmetric sloping grooves are formed in the inner cavity of each outer rectangular tube; and protruding claws corresponding to the four sloping grooves in the inner cavity of the outer rectangular tube are arranged outside the corresponding reverse rotation prevention blocks. By adopting the rotation prevention device provided by the utility model, the power tubes can not rotate, so as to improve the move precision and the positioning accuracy of the servo electric cylinder.
Description
Technical field
The utility model relates to servo electric jar, particularly a kind of anti-rotation device of servo electric jar.
Background technology
At present, the servo electric jar outer tube that uses on the domestic and international market is a rectangle, and its anti-rotation device is an idler wheel mechanism, and intensity is low, and is fragile, do not have positioning action.Some servo electric jar power pipe anti-rotation not also, very big clients want the demanded driving force pipe not rotate as required, only do rectilinear motion, use if the rotation of power pipe is influence.
Prior art discloses the patent No. is called a kind of directly-drive servo electric jar for the CN200810102853.0 name patent of invention, a kind of directly-drive servo electric jar is disclosed in the specification, comprise screw rod, nut, casing, end cap and drive system, the drive systems nut rotates on screw rod, thereby screw rod is rectilinear motion on it is axial, the outside of electronic cylinder is by casing and end cap sealing, described drive system is made of motor stator and rotor, wherein motor stator is fixed on the casing, and rotor is fixed on the nut; Described nut directly is connected or is integrated design with the inner ring of bearing; The outer ring of bearing is fixed on the casing; Be arranged on the guide pin bushing on the end cap, be used for the straight-line guiding of screw rod, dust cover is arranged on the end cap afterbody; Cooling bath is arranged in the casing, and cooling fluid circulates in cooling bath by pipe joint.Have now and directly drive electronic cylinder structure design complexity, and do not have anti-rotating function, fragile, can't locate.
Summary of the invention
For overcoming the prior art deficiency, the present utility model purpose provides a kind of anti-rotation device of servo electric jar, and this device does not make the rotation of power pipe, thus the mobile accuracy and the accurate positioning that improve servo electric jar.
The utility model comprises by power pipe, ball-screw, ball nut, counnter attack switch block, outer rectangular tube, holding screw, servomotor, the servo electric jar formed with case synchronously, described outer rectangular tube inner chamber is provided with four inclined plane grooves of mutual symmetry, and described counnter attack switch block outside is provided with four corresponding dogs of inclined plane groove with outer rectangular tube inner chamber.
Ball nut described in the utility model is cylindrical, described ball nut outer surface is provided with two screwed holes, the endoporus and the ball nut of described counnter attack switch block adapt, be provided with screw hole in the dog of described counnter attack switch block, described holding screw is linked together counnter attack switch block and ball nut by screw hole.
Power pipe described in the utility model is fixedlyed connected with ball nut, and described ball-screw is connected and fixed on the ball nut inner chamber.
The utility model remarkable advantage is:
1, this product can improve the operating accuracy and the accurate positioning of servo electric jar
2, this product can improve the useful life of servo electric jar
3, this product structure is simple, operation, easy to use.
4, this product uses reliable.

Embodiment
Now introduce the anti-rotation device embodiment of servo electric jar described in the utility model: comprise by power pipe 1, ball-screw 2, ball nut 3, counnter attack switch block 4, holding screw 5, outer rectangular tube 6, servomotor 7, the servo electric jar formed with case 8 synchronously in conjunction with Figure of description 1,2, described outer rectangular tube 6 inner chambers are provided with four inclined plane grooves 9 of mutual symmetry, and described counnter attack switch block 4 outsides are provided with four inclined plane grooves, the 9 corresponding dogs 10 with outer rectangular tube 6 inner chambers.
Ball nut described in the utility model 3 is cylindrical, described ball nut 3 outer surfaces are provided with two screwed holes 11, the endoporus of described counnter attack switch block 4 and ball nut 3 adapt, be provided with screw hole 12 in the dog 10 of described counnter attack switch block 4, described holding screw 5 is linked together counnter attack switch block 4 and ball nut 3 by screw hole 12.
Power pipe described in the utility model is fixedlyed connected with ball nut, and described ball-screw is connected and fixed on the ball nut inner chamber.
The course of work: servomotor 7 drives band and ball-screw 2 rotations synchronously; Ball-screw 2 rotates drive ball nut 3 and does rectilinear motion; Power pipe 1 is fixed together with ball nut 3, and the power pipe just can promote weight and do rectilinear motion like this.Counnter attack switch block 4 is fixed together by two holding screws 5 with ball nut 3, four inclined-plane dogs of counnter attack switch block 4 are engaged in four inclined plane groove the insides of outer rectangular tube 6 inner chambers, four inclined-plane dogs of inverse block 4 are free to slide in four inclined plane grooves of rectangular tube 6 inner chambers outside, and controlled the rotation of inverse block 4, ball nut 3 just can not rotate like this, and then power pipe 1 can not rotate yet, and only done rectilinear motion.
The utility model is not limited to above-mentioned execution mode, for those of ordinary skills, to any conspicuous improvement or the change that above-mentioned execution mode is made, can not exceed the protection range of design of the present utility model and claims.
