Description

Supporting and clamping device for fiber winding of cylindrical parts and fiber winding machine

Technical Field

The invention belongs to the technical field of fiber winding, and specifically discloses a supporting clamping device for fiber winding of a cylindrical part and a fiber winding machine.

Background technique

Filament winding technology is the most widely used composite material automated forming technology. Filament winding products have been widely and rapidly developed due to their excellent properties of light weight, high strength and corrosion resistance. The basic line types of fiber winding include circumferential winding, longitudinal winding and spiral winding. Because longitudinal winding and spiral winding can achieve a smooth transition at the closing position of the bottle mouth on both sides of the pressure vessel, longitudinal winding and spiral winding are currently mostly used in the processing of parts with closing structures at both ends such as pressure vessels. For cylindrical parts with constant outer diameter and no closing structure, they are helpless because they cannot achieve the transition of fibers during the reciprocating winding process. However, a single circumferential winding cannot meet the working requirements of cylindrical parts (such as insufficient axial strength). Therefore, it is urgent to develop a support and clamping device suitable for fiber winding of cylindrical parts, so that longitudinal winding and spiral winding can be applied to cylindrical parts to meet the working requirements of cylindrical parts.

The support block 2.5 and the support end of the support rod 2.3 are rotatably connected by bolts to flexibly adjust the support angle of the support block 2.5. A rubber layer 2.6 is attached to the support surface to increase the relative friction between the support block 2.5 and the inner wall of the cylindrical member 100, thereby playing a better supporting role.

The groove of the yarn limit block 3.3 clamps the yarn dividing rib to achieve circumferential limitation of the yarn dividing ring 3.1, and the yarn limit bolt passes through the threaded hole of the yarn limit block 3.3 to tighten the main shaft 1 so that the yarn limit block 3.3 and the yarn limit step clamp the yarn dividing ring 3.1 to achieve axial limitation of the yarn dividing ring 3.1.

Example 2

This embodiment provides a filament winding machine, which is a single filament bundle filament winding machine, such as a gantry-type single filament bundle filament winding machine or a robotic arm-type single filament bundle filament winding machine. The filament winding process is described as follows.

S1, assemble the main shaft 1 and the rib brackets, ensure that the initial opening angles of the two groups of rib brackets and the initial positions of the movable ends 2.2 of the rib brackets are relatively consistent, the main shaft 1 and the rib brackets pass through the cylindrical member 100, so that the centers of the main shaft 1 and the cylindrical member 100 coincide, and move the movable ends 2.2 of the rib brackets toward the axis of the main shaft 1 until the rib brackets firmly support the cylindrical member 100. When moving the movable ends 2.2 of the rib brackets, the movement positions of both sides are guaranteed to be consistent to ensure that the cylindrical member 100 is always coaxial with the main shaft 1.

S2, assembling the yarn separation disc and the yarn collection disc, and adjusting the relative angles of the yarn separation circles 3.1 on both sides and the yarn collection circles 4.1 on both sides according to the fiber winding angle.

S3, both ends of the main shaft 1 are respectively mounted on the single-tow fiber winding machine body 200 through a three-jaw chuck and a top, and rotate with the three-jaw chuck.

S4, longitudinal winding: the main shaft 1 rotates slowly and intermittently, and the fiber guide mechanism makes uniform circular motion in a fixed plane, guiding the fiber to pass through the yarn collecting hook and the corresponding yarn separation area on the first side, so that the fiber is wound on the surface of the cylindrical member 100, and according to the setting of the fiber winding angle, the fiber passes through the corresponding yarn separation area and the yarn collecting hook on the second side, and moves from the yarn collecting hook on the second side to the yarn collecting hook on the first side, thereby realizing the longitudinal winding process of the cylindrical member 100;

Spiral winding: the main shaft 1 rotates at a constant speed, and the fiber guide mechanism moves back and forth along the axial direction of the main shaft 1 at a specific speed, guiding the fiber to pass through the yarn collecting hook on the first side, and pass through the corresponding yarn separation area along the axial direction. The axial movement of the fiber and the circumferential rotation of the cylindrical member 100 cause the fiber to be spirally wound on the surface of the cylindrical member 100. According to the setting of the fiber winding angle, the fiber passes through the corresponding yarn separation area and the yarn collecting hook on the second side, and the fiber moves axially in the opposite direction from the yarn collecting hook on the second side, and the fiber spiral winding in the return process begins, thereby realizing the spiral winding process of the cylindrical member 100;

Hoop winding: the main shaft 1 rotates at a constant speed, the fiber guide mechanism moves in a direction parallel to the main shaft 1, and the fiber is evenly wound hoop-wise on the surface of the cylindrical member 100.

Example 3

This embodiment provides a fiber winding machine, which is a multi-tow fiber winding machine. The fiber winding process is different from that of Embodiment 2 in that multiple fiber guiding mechanisms are performed synchronously.

For a cylindrical part 100 with a constant outer diameter and no closing structure, the synchronous operation of multiple fiber guide mechanisms will lead to overlapping and accumulation of fibers. The support and clamping device for fiber winding of a cylindrical part described in Example 1 can be used to ensure that two adjacent fibers do not overlap or accumulate through the yarn separation rod 3.2, thereby ensuring the stability of the linear shape. Multiple fibers are evenly fixed on the yarn collection hook, which can ensure the consistency of the tension of multiple fibers. The support and clamping device for fiber winding of a cylindrical part described in Example 1 cooperates with the multi-tow fiber winding machine body 300 to greatly improve the production efficiency of the cylindrical part 100, and there is no crossing between fibers, thereby avoiding the stress concentration caused by the crossing of fibers during the winding of a single bundle of fibers, and the processed cylindrical part 100 has better load-bearing performance.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
