The bottom support frame is an equilateral polygon frame. A longitudinal support column is connected to each vertex angle of the bottom support frame. The tops of all longitudinal support columns are evenly connected to the bottom surface of the ring support. A transition ring support is integrally connected to the inner periphery of the ring support. An inner ring support is arranged at the center inside the ring support. An arc-shaped bracket extending towards the inner ring support is arranged at the bottom of the ring support corresponding to the position of each longitudinal support column. An intermediate ring support is arranged on the arc-shaped bracket between the ring support and the inner ring support.

[0006] The number of sides of the equilateral polygon frame of the bottom support frame is 4 to 9.

[0007] A cross support frame is fixedly connected to the bottom of the inner ring support.

[0008] A bottom fixing frame extending towards the center is connected to each vertex angle of the bottom support frame. The other end of the bottom fixing frame is connected to the bottom of the arc-shaped bracket below the inner ring support.

[0009] An intermediate support column parallel to the longitudinal support column is fixed on the bottom fixing frame. The top of the intermediate support column is connected to the bottom of the intermediate ring support.

[0010] A bottom support column is connected to the intersection middle point of the cross support frame.

[0011] The thickness of the transition ring support gradually decreases from the side connected to the ring support to the side far from the ring support.

[0012] The beneficial effects of the utility model are as follows: The structure of the utility model is stable. The arranged ring support, intermediate ring support and inner ring support form multiple supports for the arc-shaped end cover, making the arc-shaped end cover stable to place, enabling stable processing of the arc-shaped end cover, and ensuring the personal safety of the operator.

Specific embodiments

[0015] An arc end - cover processing and fixing tooling, comprising a bottom support frame 9, a longitudinal support column 8 and an annular support 1. The bottom support frame 9 is an equilateral polygon frame. One longitudinal support column 8 is connected to each vertex angle of the bottom support frame 9. The tops of all longitudinal support columns 8 are evenly connected to the bottom surface of the annular support 1. An inner - connected transition ring support 2 is integrally connected to the inner periphery of the annular support 1. An inner annular support 4 is arranged at the center inside the annular support 1. An arc bracket 7 extending towards the inner annular support 4 is arranged at the bottom of the annular support 1 corresponding to each longitudinal support column 8. An intermediate annular support 3 is arranged between the annular support 1 and the inner annular support 4 on the arc bracket 7.

[0016] The number of sides of the equilateral polygon frame of the bottom support frame 9 is 4 - 9. Corresponding to the number of sides of the equilateral polygon frame, a corresponding number of arc brackets 7 are arranged, forming an evenly - distributed support structure below the annular support 1, the intermediate annular support 3 and the inner annular support 4.

[0017] The bottom of the inner annular support 4 is fixedly connected with a cross support frame 6. A bottom support column 5 is connected at the intersection mid - point of the cross support frame 6. The bottom support column 5 is used to support the center point at the bottom of the arc end - cover, forming a support for the center of gravity.

[0018] A bottom fixing frame 11 extending towards the center is connected to each vertex angle of the bottom support frame 9. The other end of the bottom fixing frame 11 is connected to the bottom of the arc bracket 7 below the inner annular support 4. The bottom fixing frame 11, the longitudinal support column 8 and the arc bracket 7 form a stable support structure similar to a triangle.

[0019] An intermediate support column 10 parallel to the longitudinal support column 8 is fixed on the bottom fixing frame 11. The top of the intermediate support column 10 is connected to the bottom of the intermediate annular support 3. The longitudinal support column 8 is vertically or obliquely arranged on the bottom fixing frame 11.

[0020] The thickness of the transition ring support 2 gradually decreases from the side connected to the annular support 1 to the side away from the annular support 1, so that when the arc end - cover is placed on the transition ring support 2, the change in thickness better adapts to the arc structure of the arc end - cover.

[0021] During application, the arc-shaped end cover is placed inside the arc-shaped support 1. The upper surface of the arc-shaped end cover abuts against the transition ring support 2, the middle part of the arc-shaped end cover abuts against the middle ring support 3, the lower part of the arc-shaped end cover abuts against the inner ring support 4, and the center of gravity at the bottom of the arc-shaped end cover abuts against the bottom support column 5. The upper, middle, lower, and bottom parts of the arc-shaped end cover are all supported and fixed, achieving the stable support of the arc-shaped end cover.
