[0022] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] Example 1:

[0024] This embodiment 1 provides a welding fixture 1, which is used as a support and positioning tool for the welding process of a drone landing gear assembly 2. The drone landing gear assembly 2 adopts a conventional structure in the current drone technology field, so a brief description is as follows: Please refer to the attached Figure 1 As shown, the UAV landing gear assembly 2 is provided with a landing gear body 20 and a diagonal brace 21. The landing gear body 20 is composed of a first straight tube 20a and a second straight tube 20c arranged side by side at intervals, and two curved tubes 20b fixedly connected to the first straight tube 20a and the second straight tube 20c at both ends in the longitudinal direction. The diagonal brace 21 is a straight tube, inclined, and fixedly connected to the first straight tube 20a in the landing gear body 20. In addition, the number of diagonal braces 21 is not limited and can be configured to be no less than two according to the design requirements of the UAV product; Appendix Figure 1 FIG. 2 shows a situation where two diagonal braces 21 are provided, and the two diagonal braces 21 are spaced apart and arranged in parallel.

[0025] Based on the above structure of the UAV landing gear assembly 2, the structure of the welding fixture 1 preferably provided in this embodiment 1 is: Figure 3 and 4As shown, the welding fixture 1 includes a base frame 10, a plurality of first limiting members 11 spaced around the base frame 10, and a second limiting member 12 obliquely connected to the base frame 10. The plurality of first limiting members 11 can cooperate to support and position the landing gear body 20, and the second limiting member 12 can support and position the diagonal support rod 21. It can be understood that this embodiment 1 can achieve a firm support and positioning of the UAV landing gear assembly 2 by using a combination of the plurality of first limiting members 11 and the second limiting members 12, that is, it can achieve a firm fixation of the UAV landing gear assembly 2 on the welding fixture 1. Please refer to the attached figure. Figure 2 As shown; thereby, the positioning accuracy and welding quality of the UAV landing gear assembly 2 during welding operations can be effectively improved, and the production and processing requirements of the UAV can be well met.

[0026] The specific structure of the welding fixture described in this embodiment is described in detail below.

[0027] First, the preferred implementation structure of the base frame 10 in this embodiment 1 is: Figure 3 and 4 As shown, the base frame 10 is provided with a plurality of first rods 100 arranged side by side and at intervals, and a second rod 101 that fixes the plurality of first rods 100 together. Based on the overall shape of the landing gear body 20, each of the first rods 100 is provided with a first limiting member 11 at both ends in the length direction. That is, the plurality of first limiting members 11 on the plurality of first rods 100 can cooperate to support and position multiple parts on the landing gear body 20, thereby achieving a secure fixation of the landing gear body 20 on the first rod unit composed of the plurality of first rods 100 (see the attached figure). Figure 2 The second rod 101 is connected to the second limiting member 12 which is inclined relative to the second rod 101, that is, the second limiting member 12 supports and positions the diagonal support rod 21, so that the diagonal support rod 21 can be firmly fixed on the second rod 101 (see also the attached FIG. Figure 2 shown).

[0028] Further, with Figure 2 Taking the usage state of the welding fixture 1 shown as a reference, if the side-by-side direction of the plurality of first rods 100 is defined as a first horizontal direction, accordingly, each of the first rods 100 is a long rod extending along a second horizontal direction perpendicular to the first horizontal direction and having an inverted L-shaped vertical cross-section, and the second rod 101 is a long rod extending along the first horizontal direction and having an L-shaped vertical cross-section (that is, the second rod 101 extends along the side-by-side direction of the plurality of first rods 100), and the second rod 101 is also detachably fixedly connected to the plurality of first rods 100 by a plurality of screws.

[0029] Furthermore, based on the configuration quantity and arrangement of the diagonal support rods 21 in the UAV landing gear assembly 2, this embodiment 1 also has no less than two support rods 13 fixedly provided on the second rod 101 along its length direction (i.e., the first horizontal direction), and the second limiting member 12 is fixedly connected to the side of each support rod 13 facing away from the second rod 101.

[0030] Furthermore, each of the support rods 13 is a long rod extending vertically and having an inverted L-shaped transverse cross-section. At that time, the top side of each of the support rods 13 is detachably fixedly connected to a second limiting member 12 by screws, and the bottom side of each of the support rods 13 is detachably fixedly connected to the second rod 101 by screws.

[0031] As can be seen from the above, the first rod 100, the second rod 101 and the support rod 13 are all L-shaped strip plates, which are not only convenient to assemble but also have low production costs.

[0032] Next, based on the specific structure and shape of the landing gear body 20 and the diagonal brace 21 in the UAV landing gear assembly 2, the specific structure and layout of the first limiting member 11 and the second limiting member 12 are preferably designed as follows: Please continue to refer to the attached Figure 2 To the attached Figure 4 As shown, among the plurality of first rods 100, the two first rods 100 located on the outermost sides are defined as outer rods 100a, and the remaining first rods 100 located between the two outer rods 100a are defined as inner rods 100b; wherein, ① an L-shaped first limiting member 11 is fixedly connected to one end in the length direction of each of the outer rods 100a, and a T-shaped supporting limiting structure 14 composed of two L-shaped first limiting members 11 connected is fixedly connected to the other end in the length direction of each of the outer rods 100a. It can be understood that the L-shaped first limiting member 11 provided on one end in the length direction of the outer rod 100a is used to control the first 1. The straight tube 20a is supported and restricted, and the T-shaped support and restriction structure 14 provided at the other end of the outer rod 100a in the longitudinal direction is used to support and restrict the bent tube 20b and the second straight tube 20c; ② A restriction groove structure 15 formed by two L-shaped first restriction members 11 is fixedly connected at both ends of the longitudinal direction of each of the inner rods 100b (specifically, the two first restriction members 11 in the restriction groove structure are spaced apart and mirror-symmetrically arranged). It can be understood that the restriction groove structure 15 provided at both ends of the longitudinal direction of the inner rod 100b is used to clamp and restrict the first straight tube 20a and the second straight tube 20c.

[0033] In addition, each of the second limiting members 12 preferably adopts a U-shaped trough structure to clamp and limit the diagonal support rods 21 .

[0034] From the above, it can be seen that the first limiting member 11 and the limiting structure made of it (such as: T-shaped support limiting structure 14 and limiting groove structure 15), as well as the second limiting member 12 have simple structures and good installation adaptability with the base frame 10, thereby simplifying the assembly difficulty, facilitating the assembly of the welding fixture, and reducing the production cost of the welding fixture.

[0035] Finally, the prefixes "first", "second", etc. in the component names in the specification of this utility model patent (such as the first limiting member, the second limiting member, etc.) are only for the convenience of description and are not used to limit the scope of implementation of this utility model patent.

[0036] In summary, the welding fixture of the present invention can securely support and position the landing gear assembly of a drone, thereby effectively improving the positioning accuracy and welding quality during the welding operation of the drone landing gear assembly, and well meeting the production and processing requirements of drones. Moreover, the welding fixture has a simple and reasonable structure, is easy to manufacture and has a low production cost, and is easy to operate, facilitating production implementation.
