[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-3 The tooling shown includes a composite product 18, a winding machine 1, a counterweight module 12, a winding mold 17, and an auxiliary support mechanism for a single-axis composite winding process. A winding shaft 8 is horizontally mounted on the top of the winding machine 1. A four-jaw chuck 7 is connected to the drive end of the top position of the inner wall of the winding machine 1, clamping and fixing one end of the winding shaft 8. The winding machine 1 drives the winding shaft 8 to rotate. The winding mold 17 is fixedly connected to the end of the winding shaft 8 away from the winding machine 1, and the composite product 18 is fixedly wound around the outer wall of the winding mold 17. The counterweight module 12 is fixedly sleeved on the middle of the winding shaft 8, serving as a counterweight for the outer wall of the winding shaft 8. The auxiliary support mechanism is fixedly mounted inside the winding machine 1, providing auxiliary support on the winding shaft 8 located on both sides of the counterweight module 12.

[0026] During assembly, the counterweight module 12 is first installed on the winding shaft 8 and welded to both ends. Then, the winding forming mold 17 is installed at the fixed position at the end of the winding shaft 8. Next, the auxiliary support mechanism is hoisted onto the winding machine 1 for positioning. After the previously assembled winding shaft 8 is positioned on the auxiliary support mechanism, it is clamped by the four-jaw chuck 7 on the winding machine 1. In this way, the drive end of the winding machine 1 can drive the winding shaft 8 to rotate 360° through the four-jaw chuck 7. The winding shaft 8 drives the winding forming mold 17 to rotate, thereby realizing the winding forming process of the composite product 18. In this process, the counterweight module 12 can achieve the balance between the winding shaft 8 and the winding forming mold 17, ensuring the quality of the single-axis winding forming process of the composite product 18.

[0027] The auxiliary support mechanism includes a support frame 6, a bearing housing 10, and a U-shaped fixing block 9. The support frame 6 is located below the winding shaft 8 and fixed to the bottom of the winding machine 1. The bearing housing 10 is fixedly installed on the top of the support frame 6. A bearing connecting shaft 14 is fixedly connected to the inner side of the bearing housing 10. A heavy-duty roller bearing 20 is fixedly sleeved on the outer wall of the bearing connecting shaft 14. A stop washer 15 is sleeved on one end of the bearing connecting shaft 14. A round nut 16 is provided on the side of the stop washer 15 away from the bearing housing 10. The round nut 16 is threadedly connected to the outer wall of the bearing connecting shaft 14. The U-shaped fixing block 9 is movably sleeved on the outer wall of the winding shaft 8. The bottom of the U-shaped fixing block 9 is fixedly connected to the top of the bearing housing 10.

[0028] By placing the heavy-duty roller bearing 20 inside the bearing housing 10 and inserting the bearing connecting shaft 14 to connect the two, and with the assistance of the retaining washer 15 and the round nut 16, the heavy-duty roller bearing 20 can be kept stably assembled inside the bearing housing 10. The outer wall of the winding shaft 8 is placed on the heavy-duty roller bearing 20, so that the heavy-duty roller bearing 20 can be used as the rotation support of the winding shaft 8, making the rotational movement of the winding shaft 8 more stable. Then, the U-shaped fixing block 9 passes through the outside of the winding shaft 8 and is fixed to the bearing housing 10, thereby achieving the protection and fixation of the winding shaft 8 on the heavy-duty roller bearing 20.

[0029] Furthermore, a heavy-duty caster wheel 19 is fixedly installed at the bottom of the support frame 6. A guide rail is provided on the bottom inner side of the winding machine 1. A support plate 2 is fixedly connected to the winding machine 1 and located directly below the support frame 6 via the guide rail. A foot cup 4 is fixedly installed at the bottom of the support frame 6. A nut 5 is threadedly connected to the top of the foot cup 4. A fixed connecting block 3 is fixedly connected to the bottom of the foot cup 4. The nut 5 is configured on the foot cup 4, so that the fixed connecting block 3 at the bottom of the foot cup 4 can be adjusted in height by rotating the foot cup 4 on the nut 5. This facilitates the position adjustment of the support frame 6 on the winding machine 1 via the heavy-duty caster wheel 19, so as to meet the requirements of the support frame 6 to provide auxiliary support for the winding shaft 8 and to meet the requirements of adjusting the position of the winding shaft 8 when it is installed at the port of the four-jaw chuck 7. After the support frame 6 is positioned, the screw holes on the fixed connecting block 3 are used to drill threaded holes on the support plate 2. After drilling, the fixing screws are tightened to ensure that the support frame 6 and the winding machine 1 are integrated as a whole, ensuring the stability of operation.

[0030] In addition, multiple ball-head screws 13 are spaced apart on the side of the U-shaped fixing block 9 away from the winding shaft 8. The outer walls of both sides of the U-shaped fixing block 9 are fixedly connected with textured handles 21. The textured handles 21 can assist in the handling of the U-shaped fixing block 9 and improve the convenience of manual handling. The outer walls of the counterweight module 12 and the winding forming mold 17 are both fixedly connected with universal lifting rings 11. The universal lifting rings 11 facilitate the handling of the winding shaft 8 assembled with the counterweight module 12 and the winding forming mold 17.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
