Abstract
The invention discloses a center mechanism for tubular strander cradles. The center mechanism comprises a frame, a steel sleeve, a piston, a center, a first shaft, a second shaft, a cover, a disc spring, a gas pipe connector, and an intake pipe. The steel sleeve is fixedly mounted on the frame. The second shaft is disposed inside the steel sleeve. A Y-shaped rubber seal ring is arranged below the piston. The piston is fixedly mounted at the upper end of the second shaft and drives the Y-shaped rubber seal ring to move up and down on the inner side of the steel sleeve. A sealed cavity forms among the piston, the steel sleeve and the Y-shaped rubber seal ring. The disc spring sleeves the second shaft and is compressed within the steel sleeve through the cover fixedly connected with the lower end of the steel sleeve. The gas pipe connector is disposed on one side of the steel sleeve and communicated with the sealed cavity. The intake pipe is connected with the gas pipe connector. The upper portion of the piston is provided with a stop step. The first shaft is disposed in the stop step and rotatably connected with the piston. The center is fixedly mounted at the upper end of the first shaft. The center mechanism is small in size and simple and convenient to operate, positioning is accurate, and production efficiency is high.

The specific embodiment
As depicted in figs. 1 and 2, the present invention includes frame 15, steel bushing 2, piston 3, top 5, the first axle 7, the second axle 13, lid 14, belleville spring 12, gas-tpe fitting 10 and air inlet pipe 11, described steel bushing 2 is fixedly mounted in frame 15, described the second axle 13 is arranged on the inside of steel bushing 2, the bottom of described piston 3 is provided with Y type rubber seal 1, described piston 3 is fixedly mounted on the upper end of the second axle 13 and drives Y type rubber seal 1 to move up and down along the medial surface of steel bushing 2, between described piston 3, steel bushing 2 and Y type rubber seal 1, forms an annular seal space; The quantity of described belleville spring 12 is multiple and is all enclosed within on the second axle 13, described belleville spring 12 is pressed in steel bushing 2 by the lid 14 being fixedly connected with steel bushing 2 lower ends, described gas-tpe fitting 10 is arranged on a side of steel bushing 2 and communicates with described annular seal space, and described air inlet pipe 11 joins with gas-tpe fitting 10; The top of described piston 3 is provided with clamping platform, and described the first axle 7 is arranged in described clamping platform and is rotationally connected with piston 3, and described top 5 are fixedly mounted on the upper end of the first axle 7.Wherein, because the outer face of belleville spring 12 compresses with covering 14, and lid 14 is fixedly connected with steel bushing 2 end faces, has therefore guaranteed that initial condition belleville spring 12 has certain deformation quantity, with the axial force that provides to hold out against drum 16, and in the time that drum 16 is held out against, belleville spring 12 just has deformation quantity, thereby just has elastic force, only otherwise ventilate in annular seal space, top 5 just can not retract, drum 16 with regard to the moment in the state of being locked.
As shown in Figure 1, described the first axle 7 is rotationally connected with piston 3 by being arranged on bearing in described clamping platform 9, the stationarity that drum rotates when increasing unwrapping wire, and the quantity of described bearing 9 is two, described bearing 9 is by the second collar 8 axial location.
As shown in Figure 1, described top 5 are connected with the first axle 7 keys, and described top 5 by the first collar 6 axial location.
As shown in Figure 1, between the upper end of described steel bushing 2 and piston 3, be provided with O RunddichtringO 4, carry out blanketing gas.
In the present embodiment, the upper end of described the second axle 13 is threaded with piston 3.
Principle of work of the present invention is: the principle handling drum that adopts belleville spring and annular seal space combination.When in annular seal space when stuffiness, the elastic force of belleville spring 12 promotes piston 3 and axially moves up, and piston 3 promotes bearing 9, top 5 again and moves up vertically, holds out against drum 16; In the time ventilating in annular seal space, in annular seal space, pressure moment increases, to the pressure moment increase of piston 3 end faces, in the time that pressure is greater than the elastic force of belleville spring 12, belleville spring 12 is compressed, and piston 3 moves down, and drags top 5 and moves down, unclamp drum 16, take off blank panel, change dishful; After dishful places, pull out air inlet pipe 11, on piston 3 is rapid under the elastic force effect of belleville spring 12, move, drive top 5 to shoot out, hold out against dishful, complete and once change dish, without being equipped with location locking mechanism, as long as drum 16 is held out against, belleville spring 12 just has deformation quantity, thereby just has elastic force, only otherwise ventilate in annular seal space, top 5 just can not retract, drum 16 with regard to the moment in the state of being locked.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation of above embodiment being done according to the technology of the present invention essence, all still belongs in the protection domain of technical solution of the present invention.
