Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Such as Fig. 1-4, the present invention proposes a kind of distortion-free steel pipe clamp, including electric cylinder 1, centering cylinder 7, cut somebody's hair 2, slide block
4,5 and rubber ring 3 are pushed the ball；The left end of centering cylinder 7 is fixedly connected with installing plate 8, and the cylinder body of electric cylinder 1 is fixed on installing plate 8
On left side wall, the piston rod of electric cylinder 1 through installing plate 8 with centering cylinder 7 in cut somebody's hair 2 left end fix be connected, electric cylinder 1
Piston rod, centering cylinder 7 and 2 threes that cut somebody's hair are concentric；The medial wall of centering cylinder 7 is provided with through hole, and through hole is around the axis of centering cylinder 7
Uniform, be provided with one in each through hole and push the ball 5, push the ball 5 with cut somebody's hair 2 sidewall offset；The lateral wall of centering cylinder 7 is provided with leads
To bar 71, the axis of guide post 71 and the axis perpendicular of centering cylinder 7, each 5 corresponding guide posts 71 of pushing the ball；Each guiding
All be slidably connected on bar 71 slide block 4, and the lower end of slide block 45 offsets with pushing the ball, and rubber ring 3 is sleeved on the upper of whole slide block 4
End.
Above-mentioned 2 left sides of cutting somebody's hair are identical with the shape of right side, and the girth of left side is more than the girth of right side.
Above-mentioned push the ball 5 the centre of sphere to installing plate 8 right flank distance less than cut somebody's hair 2 axial length；Above-mentioned centering cylinder 7
Circlip for hole 6 is installed on medial wall, push the ball 5 the centre of sphere to circlip for hole 6 distance less than cut somebody's hair 2 axial long
Degree.
The lower center position of above-mentioned slide block 4 is provided with spherical groove 43, spherical groove 43 with push the ball 5 upper end offset.
Being fixedly connected with a slip cap 41 on the left side wall of above-mentioned slide block 4, the cross section of slip cap 41 is " П " shape, sliding
Block 4 is sleeved on guide post 71 by slip cap 41.
