[0003] In the manufacturing process of the frame of the drone disclosed in the related art, welding technology is used to weld and fix multiple supports to form the frame, wherein before welding, the scattered supports are first spliced ​​and matched in place, and then the multiple supports that are spliced ​​and matched in place are kept in a spliced ​​state and fixed by a positioning fixture for welding. Due to the unreasonable positioning setting of the current positioning fixture, before the welding of multiple supports of each frame, it takes a lot of time to adjust the positioning fixture in the process of matching with the positioning fixture to position the multiple supports, resulting in low positioning efficiency of the frame.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] See also Figure 1 , Figure 2 and Figure 4 , the positioning fixture 15 provided in the embodiment of the present application is now described. The positioning fixture 15 provided in the embodiment of the present application is used to position the frame 10 of the drone. The frame 10 includes a plurality of supports 11 and a plurality of adapters 12. Each adapter 12 is connected to two supports 11, and each support 11 is connected to two connecting members. In the embodiment of the present application, the connection method between the supports and the adapters is splicing as an example. Of course, other connection methods are also possible, as long as the adapters and the supports have a certain mutual fixing effect after being connected. Multiple adapters 12 and multiple supports 11 are correspondingly spliced ​​to obtain a frame 10 with a semi-fixed structure; define two supports 11 that can be spliced ​​with each adapter 12 They are respectively the first support 13 and the second support 14, and the splicing direction of the first support 13 and the corresponding adapter 12 is defined as the first direction, denoted by X, the splicing direction of the second support 14 and the corresponding adapter 12 is defined as the second direction, denoted by Y, and the third direction is defined as Z. The first direction, the second direction and the third direction respectively have angles and constitute a three-dimensional space direction; the first support 13 and the corresponding adapter 12 are spliced ​​and matched to fix each other along the second direction and the third direction, and the second support 14 and the corresponding adapter 12 are spliced ​​and matched to fix each other along the first direction and the third direction.

[0032] The positioning fixture 15 includes a support platform 16, a positioning assembly 17 and a plurality of pressing members 18. The support platform 16 supports the support member 11 and / or the adapter member 12 in the frame 10 along the third direction. The positioning assembly 17 includes a first positioning member 20 and a second positioning member 21. The first positioning member 20 and the second positioning member 21 respectively include at least one pair of relatively arranged limiting portions 19. The two limiting portions in each pair of limiting portions of the first positioning member 20 are relatively arranged along the first direction and are movably and adjustably arranged on the support platform 16. The two limiting portions in each pair of limiting portions of the second positioning member 21 are relatively arranged along the second direction and are movably and adjustably arranged on the support platform 16.

[0033] Each pair of limiting parts of the first positioning member 20 limits the support members 11 or adapter members 12 at both ends of the frame 10 in the first direction, and each pair of limiting parts of the second positioning member 21 limits the support members 11 or adapter members 12 at both ends of the frame 10 in the second direction; a plurality of pressing members 18 are arranged on the support platform 16, and the pressing members 18 can be arranged close to or away from the support platform 16, and each pressing member 18 is close to the support platform 16 for pressing an adapter member 12 or a support member 11 along the third direction.

[0034] The positioning jig 15 provided in the embodiment of the present application takes the frame 10 for positioning the drone as an example. The frame 10 is connected into a semi-fixed state using multiple supports 11 and multiple adapters 12, and then placed on the positioning jig 15 for positioning. In the semi-fixed state of the frame 10, for an adapter 12, the corresponding first support 13 and second support 14 cooperate to fix the adapter 12 in the first direction, the second direction, and the third direction, respectively. Similarly, for a member 11, the two adapters 12 spliced ​​with the support 11 cooperate to fix the support 11 in the first direction, the second direction, and the third direction, respectively. Of course, the positioning jig 15 provided in the embodiment of the present application can also be used to position other products with similar structural principles to the frame 10 of the drone.

[0035] In the positioning assembly 17 provided in the positioning fixture 15 of the present application, the first positioning member 20 and the second positioning member 21 respectively include at least one pair of limiting portions 19. In the first positioning member 20, the spacing area along the first direction between the two limiting portions 19 in each pair of limiting portions 19 serves as the limiting space of the support members 11 or the adapter members 12 at both ends of the frame 10 along the first direction. The corresponding setting of the two limiting portions 19 being movable and adjustable relative to the support platform 16 along the first direction can adjust the position of the pair of limiting portions 19 along the first direction and the limiting space of the pair of limiting portions 19 along the first direction. The setting of the second positioning member 21 is the same as that of the first positioning member 20, that is, in the second positioning member 21, the spacing area between the two limiting portions 19 in each pair of limiting portions 19 serves as the limiting space of the support members 11 or the adapter members 12 at both ends of the frame 10 along the first direction. The spacing area between the two limiting parts 19 along the second direction serves as the limiting space of the support 11 or the adapter 12 at both ends of the frame 10 along the second direction. The corresponding setting of the two limiting parts 19 being movable and adjustable relative to the support platform 16 along the second direction can not only adjust the position of the pair of limiting parts 19 along the second direction, but also adjust the limiting space of the pair of limiting parts 19 along the second direction. Therefore, when the first positioning member 20 and the second positioning member 21 are used for batch positioning of a frame 10, the position and distance of the two limiting parts 19 of each pair of limiting parts 19 can be fixed by one adjustment and can be repeatedly positioned and used, which can improve the adjustment efficiency of the positioning fixture 15 in mass production operation, and thus improve the positioning efficiency. Of course, according to the mutually fixed connection relationship between the support 11 and the adapter 12, the first positioning member 20 can be respectively limited to the support 11 and the adapter 12, and the second positioning member 21 can also be respectively limited to the support 11 and the adapter 12, so as to meet the limiting effect of the first direction and the second direction of the frame 10.

[0036] The multiple pressing members 18 provided in the positioning fixture 15 of the present application are used to fix the frame 10 in the third direction, thereby completing the fixation of the frame 10 in the three-dimensional direction. The principle of the force application object of the multiple pressing members 18 is similar to that of the positioning component 17, that is, the multiple pressing members 18 can act on one of the support members 11 or the adapter members 12. Of course, according to the mutually fixed connection relationship between the support member 11 and the adapter member 12, part of the multiple pressing members 18 can be used to press the support member 11, and the remaining part of the pressing members 18 can be used to press the adapter member 12, so as to meet the effect of pressing and fixing the frame 10. The present application specifically takes the example of each pressing member 18 pressing on a support member 11 or an adapter member 12, and cooperates with the supporting effect of the support platform 16 to form a relative clamping effect along the third direction, so that the frame 10 and the positioning fixture 15 are relatively fixed. When the welding of the frame 10 is completed and needs to be removed from the positioning fixture 15, the fixing effect on the frame 10 can be cancelled by moving the pressing piece 18 away from the support platform 16 to cancel the pressing effect on the support 11 or the adapter 12 along the third direction. At this time, the frame 10 can be removed from the positioning fixture 15 along the third direction. The operation is simple and quick, which helps to improve the positioning efficiency of the frame 10 and the loading and unloading efficiency.

[0037] Among them, the support platform 16 mainly plays a bearing and supporting role for the frame 10, and is also the structural basis for the positioning assembly 17 and the pressing member 18. The adjustable spacing between the two limiting parts 19 of each pair of limiting parts 19 in the positioning assembly 17 can be a separately adjustable movable setting, or it can be a fixed setting combined with another movable adjustable setting. The embodiment of the present application specifically takes the separately adjustable movable setting of the two limiting parts 19 in each pair of limiting parts 19 as an example, so that the position movement of the positioning assembly 17 can also be achieved for positioning frames 10 of different sizes, which helps to improve the versatility of the positioning fixture 15. The movable adjustment method of the limiting part 19 can be a manual adjustment setting or a drive adjustment setting, which can meet the adjustment requirements. Similarly, the pressing action of the pressing member 18 can be manually controlled or automatically controlled.

[0038] Among them, in the positioning fixture 15 of the embodiment of the present application, the first positioning member 20 and the second positioning member 21 may respectively include a pair of limiting portions 19 arranged opposite to each other, or may respectively include multiple pairs of limiting portions 19 arranged opposite to each other. When the first positioning member 20 includes a pair of limiting portions 19 arranged opposite to each other, one of the pair of limiting portions 19 of the first positioning member 20 has a limiting effect on one end of the first direction of the frame 10, and the other limiting portion 19 of the pair of limiting portions 19 has a limiting effect on the other end of the first direction of the frame 10; similarly, when the second positioning member 21 includes a pair of limiting portions 19 arranged opposite to each other, one of the pair of limiting portions 19 of the second positioning member 21 has a limiting effect on one end of the second direction of the frame 10, and the other limiting portion 19 of the pair of limiting portions 19 has a limiting effect on the other end of the second direction of the frame 10. When the first positioning member 20 includes multiple pairs of relatively arranged limiting portions 19, some of the multiple pairs of limiting portions 19 have a limiting effect on the limiting portion 19 and the support 11 or adapter 12 on one side of the first direction of the frame 10, while the remaining portions have a limiting effect on the limiting portion 19 and the support 11 or adapter 12 on the other side of the first direction of the frame 10; similarly, when the second positioning member 21 includes multiple pairs of relatively arranged limiting portions 19, some of the multiple pairs of limiting portions 19 have a limiting effect on the limiting portion 19 and the support 11 or adapter 12 on one side of the second direction of the frame 10, while the remaining portions have a limiting effect on the limiting portion 19 and the support 11 or adapter 12 on the other side of the second direction of the frame 10. Of course, when the first positioning member 20 and the second positioning member 21 respectively include multiple pairs of relatively arranged limiting portions 19, a similar arrangement of a pair of limiting portions 19 can also be adopted, that is, one limiting portion 19 in each pair of limiting portions 19 has a limiting effect on one end of the frame 10, and the other limiting portion 19 in each pair of limiting portions 19 has a limiting effect on the other end of the frame 10.

[0039] See also Figure 4In one embodiment, the first positioning member 20 and the second positioning member respectively include two pairs of limiting portions 19, each of the two pairs of limiting portions 19 in the first positioning member 20 is movably arranged along the first direction, and each pair of limiting portions 19 of the first positioning member 20 is used to position a second support member 14 in the first direction; each of the two pairs of limiting portions 19 in the second positioning member 21 is movably arranged along the second direction, and each pair of limiting portions 19 of the second positioning member 21 is used to position a first support member 13 in the second direction.

[0040] In the embodiment of the present application, the two limit portions 19 of the first positioning member 20 are used to position the second support member 14 in the first direction, and the two limit portions 19 of the second positioning member 21 are used to position the first support member 13 in the second direction. After the adapter 12 is spliced ​​with the corresponding first support member 13 and second support member 14, the second support member 14 fixes the adapter 12 and the first support member 13 along the first direction, and the first support member 13 fixes the adapter 12 and the second support member 14 along the second direction.

[0041] In the embodiment of the present application, the first positioning member 20 is positioned in the first direction of the second support member 14, so that the adapter 12 and the first support member 13 can be positioned along the first direction. Similarly, the second positioning member 21 is positioned in the second direction of the first support member 13, so that the adapter 12 and the second support member 14 can be positioned along the second direction, thereby achieving the effect of completing the positioning of the frame 10 in the first direction and the second direction.

[0042] See also Figure 2 In the above embodiment, at least one of the limiting portions 19 in each pair of limiting portions 19 is provided with a guiding portion 22, and the guiding portion 22 is arranged on the side of the corresponding limiting portion 19 away from the support platform 16, and the guiding portion 22 is used to guide the taking and placing of the support 11 or the adapter 12 between the pair of limiting portions 19.

[0043] In the embodiment of the present application, a guide portion 22 is provided on one limiting portion 19 or two limiting portions 19 in each pair of limiting portions 19, for guiding the support 11 or the adapter 12 to be placed between the two limiting portions 19 corresponding to the limiting portions 19. Specifically, the guide portion 22 can be any setting with a guiding function. In the embodiment of the present application, a guiding structure with an inclined surface is taken as an example. The inclined surface is provided on a side of a limiting portion 19 close to another opposite limiting portion 19. The processing of the inclined surface is simple and convenient, with high processing accuracy, and better guiding effect.

[0044] See also Figure 2 In the above embodiment, the positioning fixture 15 may also include a plurality of driving members 23 , which are disposed on the support platform 16 , each driving member 23 is drivingly connected to a pressing member 18 , and a driving member 23 drives the corresponding pressing member 18 to press on an adapter 12 .

[0045] In the embodiment of the present application, taking the positioning component 17 positioning the support 11 and the pressing member 18 pressing the adapter 12 as an example, a driving member 23 is provided to drive the pressing member 18 to automatically press the adapter 12 to improve the efficiency of the pressing operation. Among them, taking the driving member 23 driving the pressing member 18 to move back and forth along the third direction as an example, the pressing path of the pressing member 18 along the third direction is optimized, which helps to improve the efficiency of the pressing action. Of course, the driving member 23 can also drive the pressing member 18 along other directions or trajectories to approach or move away from the support platform 16, so as to correspondingly realize the pressing and revoking of the pressing action on the adapter 12, without limitation. Furthermore, multiple driving members 23 can be driven simultaneously or separately, without limitation.

[0046] See also Figure 2 The positioning fixture 15 in the above embodiment may also include a plurality of pads 24, and the plurality of pads 24 are arranged on the support platform 16, and each pad 24 is used to support an adapter 12. The embodiment of the present application uses pads 24 to support the adapter 12 acting on the frame 10, and the pads 24 cooperate with the pressing member 18 to fix the third direction of the adapter 12, and the pads 24 can protect the support platform 16 structure in the corresponding area from being damaged by compression. It can be understood that in actual use, the pads 24 can be set to correspond to the parts of the adapter 12 with stronger pressure resistance, so as to protect the compressive stability of the structure of the adapter 12. At the same time, if the frame 10 requires different heights of support for different orientations, it can be solved more simply, conveniently and at a lower cost by setting pads 24.

[0047] In one embodiment, the pad 24 may be provided with a protrusion (not shown in the figure) along the third direction, and the protrusion (not shown in the figure) is used to abut and position the adapter 12 along the first direction and / or the second direction. In this embodiment, each pad 24 may be provided with a protrusion (not shown in the figure), or some pads 24 may be provided with a protrusion (not shown in the figure), and the protrusion (not shown in the figure) can be used as a positioning reference in the first direction and / or the second direction of the frame 10 to assist the frame 10 in positioning in a manner of abutting along the corresponding direction, so that the frame 10 is positioned to the desired position. Of course, the protrusion (not shown in the figure) can also be set to abut against the support 11, so as to also play a positioning role as a reference for the frame 10.

[0048] It should be noted that the raised portion (not shown in the figure) can be integrally formed with the corresponding pad 24, can be installed and fixed, or can be movably connected. If the raised portion (not shown in the figure) and the corresponding pad 24 are relatively fixed, the raised portion (not shown in the figure) used as a reference is a reference determined according to the setting position of the corresponding pad 24; if the raised portion (not shown in the figure) is movably set on the corresponding pad 24, the raised portion (not shown in the figure) can be adjusted to determine the required reference according to the movement adjustment, and the positioning reference of at least one of the first direction and the second direction of the frame 10 is determined by the raised portion (not shown in the figure), and then the positioning assembly 17 and the pressing member 18 are used to cooperate to fix the frame 10 whose reference has been determined.

[0049] See also Figure 2 In one embodiment, the positioning fixture 15 may further include at least one reference block 26, which is disposed on the support platform 16, and each reference block 26 is used as a positioning reference for an adapter 12 along the first direction and / or the second direction, or each reference block 26 is used as a positioning reference for a support 11 along the first direction and / or the second direction.

[0050] Compared with the previous embodiment, in this embodiment, a reference block 26 is separately provided to serve as a positioning reference for the frame 10. The reference block 26 may be fixedly provided on the support platform 16 or may be adjustably and movably provided on the support platform 16, and both can meet the positioning reference requirements. That is, the positioning reference of at least one of the first direction and the second direction of the frame 10 is determined by the positioning block, and then the frame 10 for which the reference is determined is fixed by the positioning assembly 17 and the pressing member 18.
