[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] The following is for reference. Figures 1-3 The implementation of the sector-shaped bracket welding fixture proposed according to the embodiments of this utility model will be described in detail.

[0024] According to an embodiment of the present utility model, the fan-shaped bracket welding fixture includes: a base plate 11, and a first positioning member 12, a plurality of second positioning members 13, a plurality of third positioning members 14 and a clamping member 15 mounted on the base plate 11.

[0025] Specifically, the fan-shaped bracket has a first ring 21 to be welded, several second rings 22, several connecting rods 23, and a connecting block 24. Several second rings 22 are spaced apart on one side of the first ring 21. The connecting block 24 is located between the first ring 21 and several second rings 22. Connecting rods 23 are arranged between the first ring 21 and the second rings 22, and between the second rings 22 and the connecting block 24. A first positioning member 12 is adapted to extend into the first ring 21 to position the first ring 21. Several second positioning members 13 extend into the several second rings 22 one by one to position the second rings 22. Several third positioning members 14 define several positioning spaces to position the connecting block 24 and several connecting rods 23. A clamping member 15 can approach or move away from the first positioning space to clamp or release the clamping of the connecting block 24.

[0026] In other words, the first ring 21 is equivalent to a central fulcrum of the fan-shaped support, and the several second rings 22 are equivalent to multiple peripheral fulcrums. The first ring 21 is positioned by the first positioning element 12, and each second ring 22 is positioned by the second positioning element 13. The connecting block 24 and the connecting rod 23 are positioned by the positioning space constructed by the third positioning element 14, thereby positioning the connecting block 24 between the first ring 21 and the second ring 22, and positioning a portion of the connecting rod 23 between the corresponding second ring 22 and the connecting block 24, and positioning another portion of the connecting rod 23 between the corresponding second ring 22 and the first ring 21, so that the second ring 22 and the first ring 21 can be welded together by the corresponding connecting rod 23 to form an outer support. The second ring 22 and the connecting block 24 are welded together by the corresponding connecting rod 23 to form an inner support. The connecting block 24 of the inner support and the connecting rod 23 of the outer support are then welded together to form an integral fan-shaped support.

[0027] Thus, the first ring 21 and each of the second rings 22 are positioned by the first positioning member 12 and the second positioning member 13, and the connecting rod 23 and the connecting block 24 are positioned by the third positioning member 14, so that the positions of the first ring 21, the second ring 22, the connecting block 24 and the connecting rod 23 are relatively fixed for welding. This fan-shaped bracket welding fixture has a simple structure and can effectively position the various parts to be welded, thereby improving welding efficiency and welding quality.

[0028] Optionally, the system also includes a support block 16 disposed on the base plate 11. The support block 16 is located between the first ring 21 and the second ring 22. The support block 16 is adapted to support the connecting rod 23 and the connecting block 24, so that the connecting rod 23 and the connecting block 24 are kept on the same horizontal plane. Understandably, the support block 16 facilitates the support of each connecting rod 23 and the connecting block 24, thereby keeping them on the same horizontal plane. It also ensures the relative height of the connecting rod 23 with the first ring 21 and the second ring 22, facilitating the overall welding accuracy. Two support blocks 16 may be provided, one located at the position of the connecting block 24 and the other near the second ring 22. The specific number can be determined according to the size of the bracket.

[0029] Furthermore, the support block 16 is detachably mounted so as to be fitted onto the base plate 11 from the third positioning member 14. Understandably, the detachable nature of the support block 16 facilitates the fitting of support blocks 16 of different thicknesses onto the base plate 11 according to the height of the first ring 21 and the second ring 22, thereby improving the versatility of the tooling. Simultaneously, the third positioning member 14 can position both the connecting rod 23 and the connecting block 24, as well as the support block 16, making the overall tooling structure simpler and more compact. The third positioning member 14 can be a positioning pin, and the support block 16 has a through hole into which the positioning pin can be fitted.

[0030] Optionally, both the first positioning member 12 and the second positioning member 13 are provided with positioning bosses, and the positioning bosses have positioning portions of different diameters from bottom to top. Understandably, the positioning bosses facilitate insertion into the first ring 21 and the second ring 22 for positioning. The different diameter positioning portions from bottom to top allow for positioning of first rings 21 and second rings 22 with different diameters, thereby improving the overall versatility of the tooling. The positioning bosses can be used in conjunction with the height of the support block 16.

[0031] Furthermore, both the first positioning element 12 and the second positioning element 13 are detachably mounted on the base plate 11. Understandably, the detachable design of the first positioning element 12 and the second positioning element 13 facilitates their placement in different positions according to the different length requirements of the connecting rods 23, thereby improving the overall versatility of the tooling. Specifically, the first positioning element 12 and the second positioning element 13 can be fixed to the connecting holes on the base plate 11 by fixing pins. The fixing pins are fixedly connected to the first positioning element 12 and the second positioning element 13, and the first positioning element 12 and the second positioning element 13 can be removed and installed by plugging and unplugging.

[0032] Optionally, the clamping element 15 is a quick-release clamp. Understandably, the quick-release clamp is a standard part, readily available on the market, low in cost, and simple and reliable to operate. The quick-release clamp presses the connecting block 24 into the positioning space from its upper surface. The connecting block 24 may be trapezoidal in shape, and its two sides form parallel contact with and are welded together with the two connecting rods 23 of the outer bracket. The number of quick-release clamps can be set according to the size of the connecting block 24.
