According to technical scheme provided by the invention, said open type three points centering mechanism is rotatablely equipped with rotating shaft in connecting support; On rotating shaft, be fixed with runing rest, on runing rest, be fixed with and adhere to wheel support, first installation shaft and second installation shaft are installed in adhering to wheel support; On first installation shaft, be hinged with first installing plate and second installing plate, on second installation shaft, be hinged with the 3rd installing plate, rotating turret is provided with first swiveling wheel on first installing plate; Rotating turret is provided with second swiveling wheel on second installing plate; Rotating turret is provided with the 3rd swiveling wheel on the 3rd installing plate, on first installing plate, is hinged with first connecting rod, on second installing plate, is hinged with second connecting rod; The other end of first connecting rod and the other end of second connecting rod all are hinged on the 3rd installation shaft; The axis of the axis of first installation shaft and second installation shaft is set in parallel, and the axis of the axis of second installation shaft and the 3rd installation shaft is set in parallel, and is adhering to the up-down driver part that is provided with the 3rd installation shaft on the wheel support; One end and second installing plate of third connecting rod are hinged, and the other end of third connecting rod and the 3rd installing plate are hinged.
The driving hydraulic cylinder is installed adhering on the wheel support, the piston rod and said the 3rd installation shaft that drive hydraulic cylinder are hinged.
The present invention has following advantage: at first, rotate radially mode of entrance owing to adopted, can guarantee that so ultralong thin walled shaped piece does not have pause in the high speed spinning process, guarantee the continuity of machining process, thereby guarantee the validity that workpiece is accomplished; Secondly, adopts three of a Driven by Hydraulic Cylinder to adhere to the motion of centering wheel, on the concentric circles of the different-diameter that it is the center of circle that the center of circle that has effectively guaranteed three centering wheels is in same point always, can realize the pipe fitting realization centering function of different-diameter specification; The 3rd, adopt the way of contact of rolling relatively between centering wheel and the workpiece, can effectively avoid surface of the work to produce sliding injury or other defect, and do not influence workpiece spindle to freely extend; The 4th, owing to adopted centering swiveling wheel automatic regulating apparatus, the centering wheel can axially adjusted direction, and this can realize the centering of taper or various special pipes, and this has greatly expanded the range of application of open type three points centering mechanism.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention.
Fig. 2 is user mode figure of the present invention.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: this open type three points centering mechanism; In connecting support 7, be rotatablely equipped with rotating shaft 6, on rotating shaft 6, be fixed with runing rest 9, on runing rest 9, be fixed with and adhere to wheel support 2; First installation shaft 11 and second installation shaft 12 are installed in adhering to wheel support 2; On first installation shaft 11, be hinged with first installing plate 14 and second installing plate 15, on second installation shaft 12, be hinged with the 3rd installing plate 16, rotating turret is provided with first swiveling wheel 3 on first installing plate 14; Rotating turret is provided with second swiveling wheel 4 on second installing plate 15; Rotating turret is provided with the 3rd swiveling wheel 5 on the 3rd installing plate 16, on first installing plate 14, is hinged with first connecting rod 17, on second installing plate 15, is hinged with second connecting rod 18; The other end of the other end of first connecting rod 17 and second connecting rod 18 all is hinged on the 3rd installation shaft 13; The axis of the axis of first installation shaft 11 and second installation shaft 12 is set in parallel, and the axis of the axis of second installation shaft 12 and the 3rd installation shaft 13 is set in parallel, and is adhering to the up-down driver part that is provided with the 3rd installation shaft 13 on the wheel support 2; One end of third connecting rod 19 and second installing plate 15 are hinged, and the other end of third connecting rod 19 and the 3rd installing plate 16 are hinged.Drive hydraulic cylinder 1 adhering to be equipped with on the wheel support 2, the piston rod and said the 3rd installation shaft 13 that drive hydraulic cylinder 1 are hinged.
Ultralong thin walled pipe fitting 10 can not have break in the rotary pressing processing process, if some is former thereby cause the rotary pressing processing process to be interrupted, then cause scrapping of workpiece.Whole open type three points centering mechanism relies on and connects that support 7 is connected on the bed piece or fixing in place through other modes; When ultralong thin walled pipe fitting 10 is worked into certain position; Rotate hydraulic cylinder 8 and promote rotating shaft 6 half-twists; Rotating shaft 6 drives and drives hydraulic cylinders 1, adheres to wheel support 2, first swiveling wheel 3, second swiveling wheel 4, the 3rd swiveling wheel 5, runing rest 9 synchronous half-twists; A circle that home position is constant can be confirmed in the center of circle of first swiveling wheel 3, second swiveling wheel 4 and 5 three swiveling wheels of the 3rd swiveling wheel, and the centre of gyration of this home position and ultralong thin walled pipe fitting 10 overlaps.After rotating shaft 6 rotations put in place; Drive hydraulic cylinder 1 and begin action; Promote simultaneously first swiveling wheel 3, second swiveling wheel 4 and the 3rd swiveling wheel 5 synchronously to the centre of gyration of ultralong thin walled pipe fitting 10 near; First swiveling wheel 3, second swiveling wheel 4, the bus of the 3rd swiveling wheel 5 and the bus of ultralong thin walled pipe fitting 10 contact simultaneously, apply suitable active force by driving hydraulic cylinder 1, and first swiveling wheel 3, second swiveling wheel 4 and the 3rd swiveling wheel 5 just play the centering effect to ultralong thin walled pipe fitting 10.When ultralong thin walled pipe fitting 10 rotary pressing processing are accomplished or are needed centring means to leave, at first, drive hydraulic cylinder 1 action, drive first swiveling wheel 3, second swiveling wheel 4 and 5 whiles of the 3rd swiveling wheel to leave the outer surface of ultralong thin walled pipe fitting 10 synchronously; Second step; After first swiveling wheel 3, second swiveling wheel 4 and the 3rd swiveling wheel 5 arrive assigned addresses; Rotate hydraulic cylinder 8 and begin action, drive and drive hydraulic cylinders 1, adhere to wheel support 2, first swiveling wheel 3, second swiveling wheel 4 through rotating shaft 6 and arrive its home position with the 3rd swiveling wheel 5 and 9 while of runing rest half-twist.
