Description of the drawings
Fig. 1 is overall structure of the present invention；
Fig. 2 is split nut mechanism of the present invention sectional view.
Specific implementation mode
The invention will be further described in the following with reference to the drawings and specific embodiments, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As shown in Figure 1, a kind of automation split nut robot, including mechanical arm 1 and split nut mechanism 2, the split nut
Mechanism 2 is rotatably connected by rotating disk 3 with the mechanical arm 1, and the split nut mechanism 2 is coaxially disposed with the rotating disk 3, institute
It states mechanical arm 1 and controls the axial direction of the split nut mechanism 2 always vertically downward, ensure nut forward being inserted in lead screw, then
By the rotation of the rotating disk 3 by nut rotation set in lead screw, work in different position for convenience of the mechanical arm 1,
The pedestal following four corners of the mechanical arm 1 is provided with universal wheel 4, therefore the mechanical arm 1 can be moved arbitrarily, while to ensure
The mechanical arm 1 can be fixed in working position, and the quadrangle below the pedestal is additionally provided with support leg 5, is gone back on the pedestal
It is fixedly installed the cylinder 6 for pushing the support leg 5 to move up and down, when the mechanical arm 1 is moved to operating position, the gas
Cylinder 6 pushes the support leg 5 to move downward, and the support leg 5 props up ground, makes the mechanical arm 1 that can not move.
As shown in Fig. 2, the split nut mechanism 2 includes hollow sleeve 21 and ut socket 22, the hollow sleeve 21 1
End is fixed with the rotating disk 3, and the two coaxial arrangement, the ut socket 22 is inserted into the other end of the hollow sleeve 21, institute
It states ut socket 22 to abut by spring 23 with the fixing end of the hollow sleeve 21, the spring 23 is by the ut socket 22
To 21 outside ejection of the hollow sleeve, the ut socket 22 is equipped with the swivel nut 221 for extracting nut and is inserted into the hollow sleeve
The screw rod 222 of cylinder 21, the outer diameter of the screw rod 222 are less than the outer diameter of the swivel nut 221,21 other end of the hollow sleeve it is interior
Wall, which is equipped with, limits the first limit stupefied 211 that the swivel nut 221 rotates, when the ut socket 22 is extruded by the spring 23,
The ut socket 22 hollow sleeve 21 can be freely rotated relatively, therefore the swivel nut 221 can be with any angle set
On hex nut, after ensureing that the swivel nut 221 entangles hex nut, hex nut is not fallen out, the swivel nut 221 it is interior
Circle is dimensioned slightly smaller than the outer ring size of hex nut, and in split nut, the ut socket 22 is all pressed into the hollow sleeve
In cylinder 21, the ut socket 22 is only capable of rotating together with the hollow sleeve 21 under the limitation of first limit stupefied 211,
Therefore can under the drive of rotating disk 3 by hex nut rotation set in lead screw.
As the further technical solution of the present invention, pressure is equipped at the spring 23 and the abutting of the hollow sleeve 21
Sensor 7 judges whether hex nut is extracted by the numerical value of pressure sensor 7, while can also determine whether to start rotation
Turntable 3 tightens hex nut.
As the further technical solution of the present invention, in one end inside that the screw rod 222 is connect with the swivel nut 221
It is empty so that lead screw can enter the hollow portion of the screw rod 222 during tightening hex nut.
As the further technical solution of the present invention, the diameter of the screw rod 222 is slightly less than the interior of the hollow sleeve 21
Diameter, therefore when only screw rod 222 is located in the hollow sleeve 21, the screw rod 222 can the hollow sleeves 21 relatively
It is freely rotated, to ensure that the ut socket 22 will not be fallen out of the hollow sleeve 21,222 middle part of the screw rod is equipped with one
Spacing ring 223 outstanding is enclosed, 21 inner wall of the hollow sleeve is equipped with the limiting slot 212 coordinated with the spacing ring 223, therefore institute
Stating ut socket 22 can be axially moveable in the range of the limiting slot 212 without falling.
As the further technical solution of the present invention, the length of the swivel nut 221 is less than the described first length for limiting stupefied 211
Degree, therefore the swivel nut 221 can go deep into the hollow sleeve 21, control the depth of tightening of nut, while first limit
Stupefied 211 length is less than the length of the limiting slot 212 so that the action of the ut socket 22 at work is unrestricted.
As the further technical solution of the present invention, the second limit that limitation nut rotation is equipped in the swivel nut 221 is stupefied
224, the end of second limit stupefied 224 is equipped with the second guide angle 225 being inserted into convenient for nut, convenient for entangling hex nut,
And control hex nut movement.
As the further technical solution of the present invention, the swivel nut 221 is that hexagonal is quincunx, first limit stupefied 211
End is equipped with the first guide angle 213 being inserted into convenient for the swivel nut 221 so that the rotation of swivel nut 221 is convenient for control.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
It encloses without being limited thereto.Those skilled in the art on the basis of the present invention made by equivalent substitute or transformation, in the present invention
Protection domain within.Protection scope of the present invention is subject to claims.
