Embodiment
From Fig. 1, Fig. 2, a kind of easy-to-dismount coupling of the present invention, it comprises roller shaft head flange 1, it also comprises roller shaft head flange side land 3, transmission shaft-side land 4, swelling device, roller shaft head flange side land 3 is connected with roller shaft head flange 1, transmission shaft 2 respectively by fastening piece with transmission shaft-side land 4, contact between roller shaft head flange side land 3 and transmission shaft-side land 4, swelling device is in the space of roller shaft head flange side land 3 and transmission shaft-side land 4 inside.Specifically: roller shaft head flange side land 3 can realize being connected with roller shaft head flange 1, transmission shaft 2 respectively by stud 11, nut 10 or other fastening piece with transmission shaft-side land 4.
Wherein, swelling device comprises special-shaped block 6-1, lower special-shaped block 6-2, centering pin block 7, stud 9, match with the endoporus of roller shaft head flange side land 3 in one end of centering pin block 7, the oblate face of the other end is connected on transmission shaft-side land 4, oblate is provided with U-type groove, laid abnormity block 6-1,6-2 are separately positioned on the top and the bottom of centering pin block 7, and stud 9 passes from the screw of upper special-shaped block 6-1, the U-groove bevel of pin block 7 of feeling relieved, the screw of lower special-shaped block 6-2.Location pin block can be fixed on transmission shaft-side land 4 by screw 12.
In order to compress while realizing laid abnormity block and unclamp namely synchronous function simultaneously, in the present invention, the rotation direction contrary (one is that then another is right-handed thread to left-handed thread) of the screw on laid abnormity block 6-1,6-2, the thread rotary orientation at stud 9 two ends contrary (one end be left-handed thread then the other end be right-handed thread), and consistent with the rotation direction of the screw on the special-shaped block matched.Wherein, the centre of stud 9 is without screw thread polished rod, and polished rod length dimension is identical with the oblate thickness size of centering pin block 7, and diameter dimension is identical with the U-type groove width dimensions of centering pin block 7.
As a kind of optimal way of the present invention, from Fig. 3, Fig. 4, Fig. 5, Fig. 6, the inner groove surface A face on upper special-shaped block 6-1 top and the inner groove surface B face of lower special-shaped block 6-2 bottom are conical surface, and roller shaft head flange side land 3 and transmission shaft-side land 4 are also conical surface with the surface that A, B face contacts respectively.Conical surface can make laid abnormity block easily also very reliably be pressed on the internal surface of roller shaft head flange side land 3 and transmission shaft-side land 4, realizes being contacting and separating between roller shaft head flange side land 3 and transmission shaft-side land 4 easily.
As a kind of optimal way of the present invention, laid abnormity block 6-1,6-2 are fan-shaped, are≤the circle of 1/4.Like this, laid abnormity block can have larger activity space, can not and locate pin block 7 interfere with roller shaft head flange side land 3, transmission shaft-side land 4 in compression with when unclamping, thus the effect affecting coupling connection or unclamp.
From Fig. 7, Fig. 8, centering pin block 7 also can be able to be taper fit for cylindricality coordinates with the inner hole of roller shaft head flange side land 3.Wherein as the taper fit of optimal way, centering pin block 7 can be made to match with roller shaft head flange side land 3 more accurately more fast.
As a modification of the present invention mode, also sealed member is comprised in the present invention, sealed member comprises stuffing box gland 8, Stamping Steel Ribbon 5, and stuffing box gland 8 is enclosed within the space of roller shaft head flange side land 3 and outside, transmission shaft-side land 4 joint, and Stamping Steel Ribbon 5 is pressed in gap.
Wherein, can be fitted by plane between roller shaft head flange side land 3 and transmission shaft-side land 4, also can be meshed by end-tooth.Wherein, roller shaft head flange side land 3 and transmission shaft-side land 4 adopt end tooth to coordinate connection can transmitting torque better.
As a kind of way of realization of the present invention, the transmission of moment of torsion between roller shaft head flange side land 3 and biography axle side land 4, can be realized by dental inlay or straight end-face key.
When needing the part with roller shaft head Flange joint in more exchange device, when connection roll spindle nose flange and transmission shaft are separated, as long as coupling of the present invention rotates stud, laid abnormity block is closed, namely the conical surface of the conical surface of special-shaped block and roller shaft head flange side land, transmission shaft-side land is thrown off, the end face of roller shaft head flange side land and transmission shaft-side land separately, the transmission shaft-side that now moves right land, location pin block can depart from from the land of roller shaft head flange side, achieves the dismounting of connection roll spindle nose flange and transmission shaft; By after the part exchanging that is connected with roller shaft head flange side land, be moved to the left transmission shaft-side land, location pin block can extend in the land of roller shaft head flange side, now roller shaft head flange side land and transmission shaft-side land are affixed, rotating stud again makes laid abnormity block open, namely the conical surface of special-shaped block contacts with the conical surface of roller shaft head flange side land, transmission shaft-side land, roller shaft head flange side land and transmission shaft-side land are fitted tightly, achieves the assembling of connection roll spindle nose flange and transmission shaft.
Be described as follows: the screw on upper special-shaped block 6-1 is left-handed thread, screw on lower special-shaped block 6-2 is right-handed thread, the upper end of stud be left-handed thread lower end is under the structure of right-handed thread, time below the stud that turns clockwise, laid abnormity block can open, namely go up the same special-shaped block at present that special-shaped block moves up to move downward, the inner conical face of laid abnormity block can contact with the conical surface of roller shaft head flange side land and transmission shaft-side land respectively, and both roller shaft head flange side land 3 and transmission shaft-side land 4 are fitted tightly; When be rotated counterclockwise stud below time, laid abnormity block can close, namely go up the same special-shaped block at present that special-shaped block moves down to move upward, the inner conical face of laid abnormity block can be separated with the conical surface of roller shaft head flange side land and transmission shaft-side land respectively, both roller shaft head flange side land 3 and transmission shaft-side land 4 are separated, thus achieve both quick-detachment and assembling.Certainly, be right-handed thread at the screw of upper special-shaped block, when the screw of lower special-shaped block is left-handed thread, principle is consistent with above-mentioned, and when being only rotated counterclockwise below stud, laid abnormity block can close, and time below the stud that turns clockwise, laid abnormity block can open.
Coupler structure of the present invention is novel, as long as rotate stud gently, the connection that just can realize roller shaft head flange and transmission shaft like a cork be separated, namely realize quick-detachment and the assembling of roller shaft head flange and transmission shaft.Coupling of the present invention is both convenient, fast, effectively can shorten dead time again, reduces labor intensity.Meet the requirement of continuous-rolling work characteristics.Meanwhile, the present invention is that cold rolling factory improves quality of product, ensure that production is carried out smoothly, creates benefit.
The present invention does not limit to and the coupling starting machine transmission shaft and roller shaft head Flange joint for continuous annealing production line entrance, can be widely used in the connection between transmission shaft and equipment needing frequent dismounting yet.
