[0026] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example
[0027] Please refer to the appendix carefully. Figure 1-5A positioning device for spinning includes a placement plate 1, an L-shaped plate 2, and a base plate 3. A connecting hole 4 is provided on one side of the top of the placement plate 1. A mounting plate 5 is fixedly connected to the top of the placement plate 1 on the side away from the connecting hole 4. A positioning plate 6 is connected to one side of the mounting plate 5 via a rotating shaft. A fixing assembly 7 is provided on the outer side of the positioning plate 6. The fixing assembly 7 consists of three sets, evenly distributed circumferentially around the center of the positioning plate 6, ensuring omnidirectional stable fixing of the workpiece. Each fixing assembly 7 consists of a fixing plate 701, a fixing block 702, a threaded rod 703, a limiting plate 704, and a limiting rod 705. The fixing plate 701 is fixedly connected to the outer side of the positioning plate 6, providing a stable support foundation for the entire fixing assembly 7. A fixing block 702 is fixedly connected to one side of the bottom of the fixed plate 701. A threaded rod 703 is connected to one side of the fixing block 702 via a rotating shaft. One end of the threaded rod 703 is threaded to the outer side of the limiting plate 704, allowing the limiting plate 704 to flexibly adjust its front and rear positions by rotating the threaded rod 703, thereby tightly fitting the workpiece and achieving precise fixation. One end of the limiting plate 704 is movably connected to a limiting rod 705 via a mounting hole, effectively preventing excessive movement or offset of the limiting plate 704 during operation. A positioning mechanism 8 is provided on one side of the L-shaped plate 2. The positioning mechanism 8 includes an electric push rod 801, a second motor 802, and a core mold 803. An electric push rod 801 is fixedly connected to one side of the L-shaped plate 2, and a mounting rod 803 is fixedly connected to the other side of the electric push rod 801. A second motor 802 is provided, and its output shaft is connected to a core mold 803. A first sensor 13 is located inside the core mold 803. A second sensor 14 is located at the center of the positioning plate 6. Connecting blocks 15 are fixedly connected to both sides of the second motor 802. Telescopic rods 16 are fixedly connected to one side of the bottom of each connecting block 15. The bottom of the telescopic rods 16 is fixedly connected to the top of the placement plate 1. This not only provides stable support for the second motor 802 but also effectively absorbs vibrations generated during processing through the elastic extension and retraction function of the telescopic rods 16, further improving the stability and processing accuracy of the device. An adjusting rod 9 is fixedly connected to the bottom of the L-shaped plate 2. One end of the adjusting rod 9 cleverly passes through the placement plate 1 via a connecting hole 4, realizing an L-shape. The L-shaped plate 2 features an adjustable vertical position. A first motor 11 is fixedly mounted on one side of the connecting plate 10. The output shaft of the first motor 11 is cleverly connected to a gear 12 via a rotating shaft passing through the connecting plate 10. Multiple gear slots 17 are formed at the bottom of one side of the adjusting rod 9. The gear 12 meshes tightly with the gear slots 17. When the first motor 11 starts, the meshing of the gear 12 with the gear slots 17 drives the adjusting rod 9 to move up and down. This, in conjunction with the first sensor 13 and the second sensor 14, enables positioning. When the first sensor 13 and the second sensor 14 are on the same horizontal line, the control system stops the first motor 11, thus achieving automatic positioning of the L-shaped plate 2. This significantly improves positioning efficiency and accuracy, and reduces the tediousness and errors of manual operation.Support legs 18 are fixedly connected to the four sides of the bottom of the placement plate 1, and the bottom of the four support legs 18 is fixedly connected to the top of the base plate 3, providing stable support for the entire device and ensuring the stability and reliability of the device during operation.
[0028] The specific operation method of this utility model is as follows:
[0029] In use, the workpiece to be processed is placed on one side of the positioning plate 6, ensuring that the workpiece is tightly attached to the positioning plate 6. By rotating the threaded rod 703, the limiting plate 704 is pushed to move towards the workpiece until the limiting plate 704 is tightly attached to the workpiece, thus completing the workpiece fixation. After fixation, the first motor 11 is started, and its output shaft drives the gear 12 to rotate. Since the gear 12 meshes with the gear groove 17, the rotation of the gear 12 will drive the connecting rod to move up and down, thereby driving the entire L-shaped block to move. When the L-shaped block moves to the same horizontal line as the first sensor 13 and the second sensor 14, the control system will automatically stop the rotation of the first motor 11, thus completing automatic positioning without manual positioning. After positioning, the electric push rod 801 is driven to push the core mold 803 to move towards the workpiece and squeeze the workpiece so that it is tightly attached to the workpiece. Then, the second motor 802 is started to drive the entire workpiece to rotate, preparing for the subsequent spinning operation.
[0030] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
