Detailed ways

Please refer to the accompanying drawings, and the implementation of the present utility model will be described in detail below in conjunction with the accompanying drawings:

Below in conjunction with the embodiment shown in the accompanying drawings the utility model is further described. the

In conjunction with Figure 1, in Figure 1, there is a Mitsubishi AC servo motor 1 with a precision reducer 2 in the workbench, the AC servo motor 1 is connected to the slewing support 3, a first workbench 4 is fixed on the slewing support 3, and the workpiece is fixed on the second One on the workbench 4, so that the AC servo motor 1 can drive the workpiece to rotate. Fix a rotating column 5 on the designed distance position, fix a horizontal linear guide rail 11 on the rotating column 5, on the horizontal linear guide rail 11, two workbenches are housed, i.e. the second workbench 10 and the first Three workbenches13. By controlling the positions of the two workbenches on the horizontal linear guide rail 11, the winding of workpieces with different diameters can be realized. Wrap workpieces of different diameters. The ball screw pair and linear guide rail are used to control the fiber shaft roller according to the helix angle of fiber expansion, so that the fiber can be balanced with the spinneret, and the fiber guided by the spinneret is wound on the workpiece according to the determined helix. the

The yarn reel is installed on a mandrel with a diameter of Ф (with gap fit), and the end is provided with an upper gland 27 and a lower gland 28 to compress the reel, thereby realizing the installation of the fiber shaft roller. the

In Fig. 2, (the function of the hand crank) the servo motor drives the workpiece to rotate through the magnetic powder clutch 23, and at the other end, the motor drives the fiber shaft roller 25 to rotate, and the fiber passes through the spinning nozzle 20 and then spreads through the spreading wheel 21. Yarn, the flat fiber passes through the tension controller 24, then passes through the guide wheel 22, and finally winds up on the workpiece. The tension controller 24 measures the fiber tension by measuring the speed difference between the driven workpiece and the driven fiber shaft roller, and can feed back the measured results to the magnetic powder clutch 23 and the magnetic powder brake 26 to control the speed, thereby Fiber tension is controlled. And can realize the reverse rotation of the motor. the

In conjunction with Figure 1 and Figure 3, it is required that the fibers wound around the workpiece do not overlap or expose seams. In order to achieve orderly winding, the principle of helical winding is adopted. As mentioned above, the workpiece is driven by a Mitsubishi AC servo motor 1 equipped with a precision reducer, and rotates around the center line. And on the two vertical workbenches on the rotating column, in the second workbench 10 and the third workbench 13, the motor is connected with the ball screw through a coupling to drive it to move up and down along the workpiece centerline direction. Taking the tangent line of the workpiece as the starting point, the workpiece rotates once, and the fiber moves down by n (one fiber width). For the convenience of equipment installation, the lead of the ball screw is n1, the ball screw is located in the tangential direction of the workpiece, and the distance from the center line is n2. the

Due to the filament walking along the helical trajectory of the fiber ribbon, there will be gaps at the beginning and end of the winding. The minimum workpiece diameter is 400mm, and the exposed seam area is 4396mm2. The diameter of the workpiece is 1392mm, the theoretical maximum exposed seam area is 15298mm2, the maximum absolute error is 22859mm2, and the maximum relative error is 1.22%. 

The spinning nozzle is fixedly installed on the front end of the spinning wheel, and the ball screw is driven by a Mitsubishi servo motor 36 with a brake to drive the yarn roll to move up and down according to the helix angle, so that the fibers are always kept parallel to the spinning nozzle 33. The spinning nozzle 33 is intended to be made into a ring shape with a larger curvature. The fiber passing through the spinneret 33 is in a flat state, and the flat fiber passes through the yarn spreading wheel, the tension mechanism, and the guide wheel, and finally is wound on the outer diameter of the workpiece. A three-headed ball screw with a pitch of m is selected here. Here is the use of a servo motor with a brake. The reason is that the ball screw does not have a self-locking function. In order to ensure that the screw nut stops at a certain position, it is necessary to set up a servo motor with a brake function. the

In Figure 4, the determination of the positioning points of workpieces with different diameters: the design distance between the center O of the column and the center O1 of the rotary table is L, the maximum working stroke of the base table is L1, and the positioning of the ball screw nuts for workpieces with different diameters something different. Make the tangent OM of the workpiece diameter φD3 through the center O of the column, and then make the perpendicular line UN of the tangent OM through the tangent point U of the workpiece diameter φD3. The intersection point N of OM and UN is the positioning point of the ball screw nut with the workpiece diameter φD3. Make the tangent OQ of the workpiece diameter φD2 through the center O of the column, and then make the vertical line VP of the tangent OQ through the tangent point V of the workpiece diameter φD2. The intersection point P of OQ and VP is the positioning point of the ball screw nut with the workpiece diameter φD2. Make the tangent line OB of the workpiece diameter φD1 through the center O of the column, and then make the perpendicular line WA of the tangent line OB through the tangent point W of the workpiece diameter φD1. The intersection point A of OB and WA is the positioning point of the ball screw nut with the workpiece diameter φD1. the

Finally, it should be noted that obviously, the above-mentioned embodiments are only examples for clearly illustrating the utility model, rather than limiting the implementation manner. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or changes derived therefrom are still within the protection scope of the present utility model. the
