[0002] Metal shells have high strength and hardness, and can effectively protect the internal components from external force impacts and squeezes. Compared with materials such as plastics, metal shells can better withstand accidents such as collisions and drops, reducing the risk of equipment damage.

[0003] The machining of metal shells is a process of making metal raw materials into metal shells with the required shapes and sizes through various machining processes. When machining metal shells, a suitable clamping method can quickly and conveniently install and disassemble the metal shells, reduce the auxiliary time, and improve the machining efficiency.

[0004] The existing clamping mechanisms for metal shells usually clamp the metal shell by rotating the threaded rod to drive the clamping block. When it is necessary to release the fixation of the metal shell, the clamping block is driven to move by rotating the threaded rod in the reverse direction to release the clamping of the metal shell. When clamping another metal shell of the same specification, it is necessary to repeat rotating the threaded rod to drive the clamping block to move down, and the operation is relatively cumbersome. Therefore, a multi-angle clamping mechanism for machining metal shells is proposed to solve the above problems. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1 - 4, an embodiment provided by the present utility model: a multi-angle clamping mechanism for machining of a metal shell, including a machine base 1. The machine base 1 provides support for the rotation of a rotating column 4 and provides a site for the installation of a motor 2. The front inner wall of the machine base 1 is rotatably connected to a rotating column 4. The rotating column 4 can rotate on the inner wall of the machine base 1 through a limiting ring 8. A chute is provided at the front end of the rotating column 4 to facilitate the movement of a connecting block 11. An outer wall of the rotating column 4 is fixedly connected to a limiting ring 8. The outer wall of the limiting ring 8 slides on the front inner wall of the machine base 1 to limit the rotation of the rotating column 4 within the machine base 1. A fixed column 18 is fixedly connected to the front inner wall of the rotating column 4. The fixed column 18 provides support for the rotation of a first gear 14. The outer wall of the fixed column 18 is rotatably connected to a first gear 14. The first gear 14 drives the movement of a rack 7 engaged at the right end by the movement of the engaged rack 7. The left outer wall of the first gear 14 is engaged with a rack 7. The rack 7 drives the rotation of the first gear 14 through the movement of a connecting block 11. The racks 7 are symmetrically arranged. The rear outer wall of the rack 7 slides on the inner wall of the rotating column 4. The upper outer wall of the rack 7 is fixedly connected to a connecting block 11. The connecting block 11 provides support for the rotation of a threaded rod 5. The movement of the connecting block 11 drives the movement of the rack 7 and a fixed block 12. The upper inner wall of the connecting block 11 is threadedly rotatably connected to a threaded rod 5. The threaded rod 5 is threadedly connected to the upper inner wall of the rotating column 4. The rotation of the threaded rod 5 drives the movement of the connecting block 11. A fixed block 12 is fixedly connected to the front outer wall of the connecting block 11. A receiving groove is provided in the bottom inner wall of the fixed block 12 for receiving a clamping block 13. The bottom inner wall of the fixed block 12 is slidably connected to a clamping block 13. There are two clamping blocks 13, and the two clamping blocks 13 are symmetrically arranged. The two clamping blocks 13 are used to clamp the outer wall of the metal shell. The upper inner wall of the clamping block 13 is rotatably connected to a moving rod 6. The movement of the moving rod 6 drives the synchronous movement of a limiting plate 15 and the clamping block 13. The outer wall of the moving rod 6 penetrates and is slidably connected to the upper inner wall of the fixed block 12. A limiting plate 15 is fixedly connected to the outer wall of the moving rod 6. When the outer wall of the limiting plate 15 slides into the upper inner wall of the fixed block 12 along with the movement of the moving rod 6, the limiting plate 15 is rotated by ninety degrees by rotating the moving rod 6. The position of the limiting plate 15 is limited by a slider 16, and the position of the moving rod 6 is fixed by the limiting plate 15. A limiting component is provided on the upper inner wall of the fixed block 12, and the limiting component is used to limit the limiting plate 15. An adjusting component is provided on the rear outer wall of the rotating column 4, and the adjusting component is used to adjust the angle of the rotating column 4.

[0032] Refer to Figure 1 and Figure 2, the adjustment component includes a fixed plate 3. The rotation of the second gear 10 drives the rotation of the rotating column 4, thereby adjusting the angle of the metal shell. The outer wall of the fixed plate 3 is serrated and meshed with the outer wall of the second gear 10. The front outer wall of the fixed plate 3 is fixedly connected to the rear outer wall of the rotating column 4. A motor 2 is fixedly connected to the upper end of the machine base 1. The operation of the motor 2 is used to drive the rotation of the rotating shaft 9. The rear inner wall of the machine base 1 is rotatably connected to the rotating shaft 9. The rotation of the rotating shaft 9 drives the rotation of the second gear 10 through the operation of the motor 2. The rear inner wall of the rotating shaft 9 is fixedly connected to the output shaft of the motor 2. The outer wall of the rotating shaft 9 is fixedly connected to the second gear 10. The rotation of the second gear 10 drives the rotation of the fixed plate 3 through the rotation of the rotating shaft 9.

[0033] Referring to Figure 3 and Figure 4 , the limiting component includes a slider 16. After the upper outer wall of the slider 16 is squeezed by the limiting plate 15, the slider 16 moves downward to squeeze the spring 17. When the slider 16 rotates 90 degrees, the slider 16 pops up upward and is clamped on the bottom inner wall of the limiting plate 15. The upper outer wall of the slider 16 is hemispherical. The outer wall of the slider 16 is slidably connected to the upper inner wall of the fixed block 12. The bottom outer wall of the slider 16 is elastically connected to the upper inner wall of the fixed block 12 through the spring 17. One end of the spring 17 is fixedly connected to the upper inner wall of the fixed block 12, and the other end of the spring 17 is fixedly connected to the bottom outer wall of the slider 16.

[0034] Working principle: Place the metal shell between the clamping blocks 13. By rotating the threaded rod 5, the rotation of the threaded rod 5 drives the connecting block 11 to move towards the center. The movement of the connecting block 11 drives the toothed plate 7 and the fixed block 12 to move towards the center. The movement of the toothed plate 7 drives the toothed plate 7 on the other side through the first gear 14. Clamp the metal shell with the clamping blocks 13 on both sides to process the metal shell. When the clamping angle needs to be adjusted, start the motor 2. The rotation of the rotating shaft 9 and the second gear 10 drives the rotation of the fixed plate 3. The rotation of the fixed plate 3 drives the rotation of the rotating column 4 to adjust the angle of the metal shell. After processing, rotate the moving rod 6 by 90 degrees to make the upper outer wall of the limiting plate 15 coincide with the chute at the upper end of the fixed block 12, so as to easily move the limiting plate 15 and the clamping blocks 13 upward by the moving rod 6 to release the clamping of the metal shell.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
