[0023] In order to enable those skilled in the art of the present technology to better understand the technical solution of the present invention, the following will describe its specific implementation manners in detail with reference to the accompanying drawings:

[0024] Please refer to Figures 1 to 4 , an embodiment of the present invention, a positioning device for a polygonal structure body. The polygonal structure body has multiple layers. The positioning device includes multiple cover plates 10. The number of cover plates 10 is the same as the number of layers of the polygonal structure body. The number of cover plates is determined according to the number of layers of the polygonal structure body. The multiple cover plates 1 correspond to the multiple layers of the polygonal structure body one by one; each cover plate 10 is a fan-shaped arc plate with inner and outer arcs. Along the arc direction of each cover plate, a number of positioning holes 101 are sequentially opened. The number of positioning holes 101 is set according to needs; angle alignment lines are engraved around each positioning hole; the pitch circles of the positioning holes on each cover plate are consistent with the pitch circles on the paired polygonal structure body; four cover plate lifting threaded holes 102 are evenly distributed around the positioning hole at the center of each cover plate, which is convenient for lifting and placing the cover plate; both ends of each cover plate 1 are milled flat, and the four corners are rounded.

[0025] A positioning block 2 is rotatably arranged in each positioning hole 101. The positioning block 2 is in the shape of a hollow cylinder. The top of the outer peripheral surface of the positioning block 2 has a two-level stepped structure 21. The bottom of the outer peripheral surface of the positioning block 2 has a polygonal shape 22 adapted to the corresponding polygonal structure body. A positioning alignment line is provided on the outer circumferential surface at the top end of the positioning block 2; a rotation tool connection hole 23 that penetrates up and down is provided in the middle of the top end of the positioning block 2. Two positioning block lifting threaded holes 24 are provided at the top end of the positioning block 2. The two positioning block lifting threaded holes 24 are located on the radial sides of the rotation tool connection hole 23. The positioning block lifting threaded holes 24 are convenient for lifting and placing the positioning block. The rotation tool connection hole 23 is a threaded hole, which is convenient for auxiliary connection of a rotation tool. The rotation tool connected to the rotation tool connection hole 23 by threads drives the positioning block 2 to rotate in the positioning hole 101.

[0026] The bottom of the positioning block 2 is connected to the polygonal structure body. When the positioning block 2 rotates in the positioning hole 101, it drives the corresponding polygonal structure body to rotate until the positioning alignment line on each positioning block 2 is aligned with the angle alignment line on the corresponding positioning hole 101.

[0027] On the surface of each cover plate 1, there are group alignment indicating markings engraved, and on the top surface of each positioning block 2, there are group alignment scale grooves corresponding to the group alignment indicating markings, which facilitates the alignment of the cover plate 1 with the corresponding positioning block 2.

[0028] Please refer to Figure 5 , Figure 6 and Figure 7 , in this embodiment, the polygonal structure has three layers: an inner ring, a middle ring, and an outer ring; correspondingly, the number of cover plates 1 is three, and the three cover plates are respectively an inner ring cover plate 11, a middle ring cover plate 12, and an outer ring cover plate 13; the number of positioning holes 101 on each cover plate is three, and the three positioning holes 101 facilitate operation and ensure the levelness and stability of the plate surface. The inner ring cover plate 11 and the positioning blocks 2 in its positioning holes are used to position the polygonal structure of the inner ring; the middle ring cover plate 12 and the positioning blocks 2 in its positioning holes are used to position the polygonal structure of the middle ring; the outer ring cover plate 13 and the positioning blocks 2 in its positioning holes are used to position the polygonal structure of the outer ring. The sizes of the three cover plates are the same; the pitch circles of the positioning holes on the same cover plate are the same, and the pitch circles of the positioning holes on different cover plates are different; the diameters of all the positioning holes are the same.

[0029] The positioning block 2 and the cover plate 10 are respectively made of stainless steel plate material. For example, the positioning block is processed from a stainless steel rod, and the cover plate is processed from a steel plate material.

[0030] The bottom of the positioning block is inserted into the polygonal structure. When the positioning block rotates in the positioning hole, it drives the corresponding polygonal structure to rotate, and the positioning alignment markings on each positioning block are aligned with the angle alignment lines on the corresponding positioning hole.

[0031] When the positioning device of the polygonal structure of the present invention is in use, the positioning holes on the cover plate 10 are sleeved on the corresponding polygonal structures, and the positioning holes on the inner ring cover plate 11, the middle ring cover plate 12, and the outer ring cover plate 13 are sleeved on the polygonal structures of the inner ring, the middle ring, and the outer ring in a one-to-one correspondence. The bottom of the positioning block 1 is assembled and clamped with the pre-installed polygonal structure. When the positioning block rotates in the positioning hole, it drives the corresponding polygonal structure to rotate until the positioning alignment markings on each positioning block are aligned with the angle alignment lines on the corresponding positioning hole, respectively realizing the angle positioning of the polygonal structures of the inner ring, the middle ring, and the outer ring. The entire positioning device is small, flexible, easy to operate, and the positioning is convenient and accurate. It effectively solves the problems of inaccurate angle positioning of the polygonal structure during the assembly process and inconsistent positioning angles of multiple polygonal structures. For the next alignment, one or more of the positioning holes can be sleeved on the polygonal structure that has been positioned, and then the remaining positioning holes can be aligned in sequence to ensure the consistency of the angles of the polygonal structures in the whole circle.

[0032] In summary, the positioning device for the polygonal structure of the present invention can achieve precise positioning of the polygonal structure with circumferentially uniform arrangement and angular requirements. It has a relatively simple structure, is convenient for disassembly and assembly, easy to maintain, uses common materials, has a low cost, can be made into multiple sets for simultaneous use, greatly improves the accuracy and efficiency of pairing and assembly, and meets the requirements of high-precision positioning.
