Embodiment
Describe to be used to disclose the present invention below so that those skilled in the art can realize the present invention.It is excellent in describing below
Embodiment is selected to be only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
A kind of nut Auto-lock Machine structure as Figure 1-3, including for installation into the mounting bracket 1 on assembly line, support
In mounting bracket 1 structure is screwed to the clamping structure that clamps nut and to rotate the nut after clamping.
The clamping structure include by cylinder mounting plate 32 be fixed on the side of mounting bracket 1 hollow cylinder 3, with it is hollow
The clamp sleeve 6 and nut chuck 7 of the threaded one end connection of the remote mounting bracket 1 of the hollow cylinder bar 32 of cylinder 3, it is described
Nut chuck 7 is arranged on clamp sleeve 6 and can slided relative to clamp sleeve 6 is relative, one end of the nut chuck 7
Stretched out from one end of the remote hollow cylinder 3 of clamp sleeve 6, and nut chuck 7 is provided with from one end that clamp sleeve 6 stretches out
To receive the nut interface 73 of nut.The hollow cylinder 3 uses prior art.
Specifically, the multiple slits 71 extended along its axis direction are provided with the nut chuck 7, the slit 71 exists
It is uniformly arranged on the circumferencial direction of nut chuck 7, and each slit 71 originates in one of nut chuck 7 with nut interface 73
End, terminates at nut interface 73 and nut chuck 7 is located between the end in clamp sleeve 6.Also, the nut chuck 7 is
Hollow structure, the slit 71 are communicated with the hollow sections of nut chuck 7 in order to one of nut chuck 7 with nut interface 73
End along radial contraction and then can compress nut.
Effectively nut can be compressed in order to facilitate clamp sleeve 6, in the outer rim of nut chuck 7 with nut interface pair
The opening position answered is provided with projection 74, and raised 74 maximum gauge is more than the diameter of clamp sleeve 6 and then works as hollow cylinder 3
Clamp sleeve 6 is driven effectively to reduce the diameter of nut interface 73 when moving downward by extruding, so as to realize nut
Clamp.The nut chuck 7 is made of elastomeric material, and when 6 no longer expression lobes 74 of clamp sleeve, nut interface 73 can
Automatically original size is recovered.
The structure that screws includes being fixed on motor 2, one end and the motor of the opposite side of mounting bracket 1 by electric machine support 21
2 rotary shafts 5 connected by shaft coupling 22, the other end of the rotary shaft 5 pass through from the hollow cylinder bar 31 of hollow cylinder 3
It is fixedly connected with nut chuck 7, motor 2 can realize tightening for nut by driving nut chuck 7 to rotate.
Specifically, the rotary shaft 5 can not be connected with the relative rotation with hollow cylinder bar 31, so drive spiral shell in motor 2
Also drive clamp sleeve 6 to rotate simultaneously when female chuck 7 rotates and then clamp sleeve 6 can be avoided to be rotated against with nut chuck 7
And rub, it can so improve the service life of nut chuck 7.
In order to ensure the stability of nut chuck 7 when rotated, pivot flange 4, institute are provided with the outer sheath of clamp sleeve 6
State and bearing 61 is provided between pivot flange 4 and clamp sleeve 6 to reduce friction when rotating.In order to avoid clamp sleeve 6 exists
Directly contacted with bearing 61 to be caused damage to bearing 61 when moving up and down, set is provided between bearing 61 and clamp sleeve 6
Pipe 62.
The pivot flange 4 is fixed in mounting bracket 1 by attachment screw 41, and the attachment screw 41 passes through middle air
Mounting hole on cylinder 3 is installed on cylinder mounting plate 32, and centering air cylinder 3 and support so can be achieved by attachment screw 41
The fixation of flange 4, simplifies structure.In order to avoid up and down motion of the pivot flange 4 to hollow cylinder bar 31 produces interference, even
Connect on screw 41 and be arranged with branch sleeve 42 between pivot flange 4 and hollow cylinder 3 so that pivot flange 4 and middle air
There is certain space between cylinder 3.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
