[0033] Reference Figure 1 、 Figure 3 and Figure 6 The utility model provides an embodiment of a middle frame riveting tool, including a platform 1 and a base 11. The top of the platform 1 is equidistantly provided with a plurality of bottom plates 2, which are threadedly connected to the platform 1 through a fixing bolt 10. Supports 3 are provided on the left and right sides of the top of the bottom plate 2. The top of the support 3 is fixedly connected to the top plate 4. The bottom plate 2 and the top plate 4 are connected by the function of the support 3. The top of the top plate 4 is fixedly connected with a shaped tire 5. The left and right sides of the top of the shaped tire 5 are fixedly connected with hinge bolts 6. The middle part of the outer wall of the shaped tire 5 is fixedly connected with a forming plate 7. The outside of the forming plate 7 is provided with a frame ring 8. The frame ring 8 is engaged with the forming plate 7 by the function of the shaped tire 5. The position of the frame ring 8 is limited by the function of the shaped tire 5. The left and right ends of the frame ring 8 are fixedly connected with a connecting plate 9; the bottom of the support leg 15 is fixedly connected with a connecting piece 2 16, and the outer wall of the connecting piece 2 16 is equidistantly provided with a plurality of threaded holes 2 17, and the device is supported by the function of the support leg 15;

[0034] Specifically, when performing the riveting operation on the middle frame, the frame ring 8 is placed inside the arc surface of the forming plate 7 to ensure that the two can achieve a good fit, and the excess material in the frame ring 8 is cut off to ensure that its size meets the design requirements. The frame ring 8 and the connecting plate 9 are clamped together using a bow clamp to ensure that the two are tightly combined, and the connecting plate 9 is in the gap position of the forming tire 5. This can ensure that the external dimension tolerance and roundness index of the entire middle frame meet the predetermined standards, and the top plate 4 and the forming tire 5 are effectively supported by the support 3, thereby ensuring that the entire riveting operation is carried out in a stable state, and the connection of the bottom parts of the support leg 15 can be achieved through the connecting piece 2 16.

[0035] Reference Figure 2 、 Figure 4 and Figure 5 The top of the base 11 is provided with a plurality of threaded holes 12 at equal intervals.

[0040] Specifically, the structure of the support plate 20 is reinforced by the fixing plate 22 to further improve the stability, and the impact of collision on the support platform 11 is reduced by the second foam ring 24.

[0041] Working principle: When riveting the middle frame, the frame ring 8 is placed inside the arc surface of the forming plate 7 to achieve locking, and the excess part is cut off. The frame ring 8 and the connecting plate 9 are clamped by the bow clamp. At this time, the connecting plate 9 to be riveted is in the pore position of the forming tire 5, thereby ensuring the external dimension tolerance and roundness index of the entire middle frame. During this process, the top plate 4 and the forming tire 5 are supported by the support 3 to achieve stability during the riveting process;

[0042] Before riveting, the positioning bolt 13 is fixed through the threaded hole 12, and the connecting piece 14 is threadedly connected to the bottom of the base 11 by utilizing the positioning bolt 13, thereby fixing the support leg 15, supporting the entire riveting tooling, and achieving the overall stability of the riveting tooling.
