[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 the drone arm 2. The drone arm 2 adopts the conventional structure in the current drone technology field, so the brief description is as follows: Please refer to the attached Figure 1 As shown, the drone arm 2 includes a cylindrical arm body portion 20 and an arm base portion 21 coaxially sleeved on the outside of one end of the arm body portion 20. A mounting lug with a bifurcated structure is fixedly provided on the outer surface of the other end of the arm body portion 20, and a mounting hole A22 is provided on the mounting lug. A mounting hole B23 is provided on the arm base portion 21. The mounting holes B23 are configured as at least two, and respectively adopt a circular hole structure and a rectangular hole structure.

[0025] Based on the above structural design of the drone arm 2, the structure of the welding fixture 1 preferably used in this embodiment 1 is: Figure 2 As shown, the welding fixture 1 includes a base plate 10, and a first support seat 11 and a second support seat 12 which are spaced apart from the base plate 10 and are used to support the arm body part 20 and the arm seat part 21 respectively, and the first support seat 11 is provided with a limiting member A that can limit and position at least two different parts of the arm body part 20, and the second support seat 12 is provided with a limiting member B13 that can limit and position the arm seat part 21. It can be understood that the method of using the welding fixture 1 is: while and / or after placing the arm body part 20 (specifically the other end of the arm body part 20) and the arm seat part 21 of the drone arm 2 on the first support seat 11 and the second support seat 12 respectively, the arm body part 20 and the arm seat part 21 can be respectively restricted and positioned by the restriction member A and the restriction member B13, so that the drone arm 2 can be firmly restricted and positioned on the welding fixture 1, which is beneficial to improving the positioning accuracy and welding quality of the drone arm 2 welding operation, reducing labor costs, and improving the operational safety of the welding operation.

[0026] The specific structure of the welding fixture 1 described in this embodiment 1 is described in detail below.

[0027] First, in order to describe the structure of the welding fixture 1 clearly and concisely, the following "orientation" is defined in this embodiment 1: based on the use state of the welding fixture 1, the first support seat 11 and the second support seat 12 are spaced apart along the axial direction of the arm portion 20 and are fixedly arranged on the upper side of the base plate 10. It can be understood that ① the first support seat 11 and the second support seat 12 are arranged side by side, and the side-by-side arrangement direction of the first support seat 11 and the second support seat 12 is parallel to the axial direction of the arm portion 20 (see the attached figure). Figure 2 and attached Figure 3 ② The first support seat 11 and the second support seat 12 can be fixedly arranged on the upper side of the base plate 10 by welding, gluing or riveting respectively. Furthermore, this embodiment 1 preferably adopts riveting to fix the first support seat 11 and the second support seat 12 to the base plate 10 respectively.

[0028] Next, let's discuss the first support base 11 and the limiting member A thereon.

[0029] Based on the above-mentioned structure of the drone arm 2, in this embodiment 1, the limiting member A is preferably configured as two, defined as a first limiting member A14 and a second limiting member A15. The first limiting member A14 can be inserted into the mounting hole A22 on the arm portion 20 with a slightly tight fit, and the second limiting member A15 can be firmly pressed against the outer surface of the arm portion 20. That is, through the plug-in positioning relationship between the first limiting member A14 and the mounting hole A22, and the pressing positioning relationship between the second limiting member A15 and the arm portion 20 (the limiting member A provides a dual limiting effect on the arm portion 20), the arm portion 20 (specifically, the other end of the arm portion 20) can be firmly restricted and positioned on the first support seat 11. Note: The above-mentioned "slightly tight fit" means that when the first limiting member A14 is inserted into the mounting hole A22, there is no gap between the two. However, when the first limiting member A14 is separated from the mounting hole A22, this can be achieved by applying a small force.

[0030] For further information, please refer to the attached Figure 2As shown, the first limiting member A14 adopts a positioning pin and is fixedly set on the upper side of the first support seat 11; the second limiting member A15 adopts an elbow clamp (also known as a horizontal quick clamp) and is positioned above the first support seat 11. It can be understood that when the arm body part 20 of the drone arm 2 (specifically the other end of the arm body part 20) is placed on the first support seat 11, the positioning pin is inserted into the mounting hole A22 to achieve preliminary limiting positioning of the other end of the arm body part 20. The operation is simple and convenient, and the positioning effect is good; then the operator manually operates the elbow clamp to perform secondary limiting positioning on the other end of the arm body part 20. The operation is simple and convenient, and the clamping and positioning effect is good; thereby achieving the other end of the arm body part 20 being firmly limited to the first support seat 11. Please refer to the attached Figure 3 shown.

[0031] For further information, please refer to the attached Figure 2 As shown, the first support seat 11 adopts a U-shaped block structure with the notch facing upward, the first limiting member A14 is tightly fitted or screwed on the top side of the first support seat 11, and the second limiting member A15 is fixedly connected to the inner wall of the bottom of the groove of the first support seat 11 through the column 16. Specifically: the column 16 is integrally formed with the first support seat 11, and the second limiting member A15 is detachably mounted on the top side of the column 16 by screws.

[0032] Next, let's discuss the second support base 12 and the limiting member B thereon.

[0033] Based on the above structure of the drone arm 2, this embodiment 1 makes the following preferred design for the limiting member B13: the limiting member B13 adopts a block structure that matches the shape of the mounting hole B23 on the arm base portion 21 and can be inserted into the mounting hole B23 with a slightly tight fit, and the limiting member B13 is also fixed on the upper side of the second support seat 12. It is understandable that when the arm base portion 21 of the drone arm 2 is placed on the second support seat 12, the limiting member B13 is inserted into the mounting hole B23 with a slightly tight fit to securely limit the positioning of the arm base portion 21, thereby achieving a secure limit of the arm base portion 21 on the second support seat 12. Please refer to the attached Figure 3 shown.

[0034] For further information, please refer to the attached Figure 2As shown, the limiting member B13 has a rectangular or circular block structure; and the limiting member B13 can be fixedly connected to the second support base 12 by any one of welding, gluing, riveting, and integral molding. Furthermore, in this embodiment 1, the limiting member B13 is preferably fixedly connected to the second support base 12 by integral molding.

[0035] For further information, please refer to the attached Figure 2 As shown, the second support seat 12 adopts a rectangular block structure that matches the shape of the arm seat part 21.

[0036] Next, let’s talk about other structures.

[0037] Please continue to refer to the attached Figure 2 As shown, in this embodiment 1, a handle 17 for the operator to hold is fixedly provided on the upper side of the base plate 10, that is, the operator can move the welding fixture 1 through the handle 17. In addition, the handle 17 is detachably mounted on the base plate 10 by screws.

[0038] Finally, the prefixes "first", "second", etc. of the component names in the specification of this utility model patent (such as the first support seat, the second support seat, etc.), and the suffixes "A", "B", etc. of the component names (such as the restriction member A, the restriction member B, etc.) are only for the convenience of description and are not used to limit the scope of implementation of this utility model patent.

[0039] In summary, the UAV arm welding fixture of the present invention can securely position the UAV arm, effectively improving the positioning accuracy and welding quality of the UAV arm welding operation, while reducing labor costs and enhancing operational safety. Furthermore, the UAV arm welding fixture has a simple and rational structure, making it easy to manufacture and inexpensive, while also being easy to operate and facilitating production implementation.
