[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1 - Figure 4 As shown, this application provides a welding fixture for assembling a sound outlet, including: a mounting base plate 1, a positioning plate 2 connected to the top of the mounting base plate 1, and a top plate 3 connected to the top of the positioning plate 2, and a ventilation pipe 20 installed on the inner side of the mounting base plate 1.

[0026] The top of the positioning plate 2 is provided with a pre-positioning adjustment component, which includes a sliding pressing block 6, and a pre-positioning clip 8 is connected to the inner bottom end of the sliding pressing block 6. An elastic connector 10 is connected to the outer side of the pre-positioning clip 8. The pre-positioning adjustment component is used for the pre-positioning of assembled parts.

[0027] Specifically, such as Figure 2 As shown, a positioning groove 4 is provided in the middle of the inner side of the positioning plate 2. The positioning groove 4 is used to snap and position the assembly positioning block 12. A sliding groove 5 is provided on the outer side of the top of the positioning plate 2. There are two sliding grooves 5 to facilitate the sliding and guiding adjustment of the sliding extrusion block 6 inside the sliding groove 5.

[0028] Specifically, such as Figure 2 As shown, the sliding extrusion block 6 is slidably connected to the inner side of the slide groove 5, and both sides of the top of the sliding extrusion block 6 are fixedly installed with a toggle block 7. The movement of the toggle block 7 will drive the sliding extrusion block 6 to adjust its position.

[0029] Specifically, such as Figure 2As shown, the prepositioning clip 8 is slidably connected to both ends of the inner side of the positioning plate 2, and the top of the prepositioning clip 8 is fixedly connected to the limiting post 9. The sliding pressing block 6 has an inclined groove inside, which will press the limiting post 9 during the pushing process, thereby driving the prepositioning clip 8 to move.

[0030] Specifically, such as Figure 2 As shown, the inner side of the top plate 3 is provided with a toggle groove 11 that is slidably connected to the toggle block 7. The toggle groove 11 is used to limit the toggle position of the toggle block 7.

[0031] The positioning plate 2 is provided with a synchronous welding assembly, which includes a side push plate 13 and a ventilation plate 18 is provided on the inner side of the side push plate 13. The synchronous welding assembly is used to weld parts while assembling them.

[0032] Specifically, such as Figure 3 As shown, the inner side of the positioning groove 4 is connected to the assembly positioning block 12, and the side push plate 13 is connected to both sides of the bottom end of the assembly positioning block 12. The side push plate 13 slides on both sides to facilitate clamping and positioning of the assembly positioning block 12.

[0033] Specifically, such as Figure 3 As shown, the inner side of the assembly positioning block 12 is connected to the sound outlet body 15, and the outer side of the sound outlet body 15 is connected to the welding spring 16. The sound outlet body 15 and the welding spring 16 are fixed inside the assembly positioning block 12 for easy welding.

[0034] Specifically, such as Figure 4 As shown, the bottom end of the assembly positioning block 12 is connected to a ventilation connecting block 14, and the ventilation plate 18 is connected to the inner top of the ventilation connecting block 14. The top of the ventilation plate 18 is fixedly connected to a connector 17, and a welding post 19 is installed on the top of the connector 17. By setting multiple welding posts 19 on the top of the connector 17, corresponding to the welding assembly positions of the welding spring 16 and the sound outlet body 15, synchronous welding is facilitated and stability is improved.

[0035] In this embodiment: when welding and positioning the mouthpiece body 15 and the welding spring 16, the position of the prepositioning clip 8 is adjusted by moving the sliding extrusion block 6. After adjustment, the elastic force of the elastic connector 10 drives the prepositioning clip 8 to limit and extrude the mouthpiece body 15, thereby improving the stability during subsequent fixed welding. When assembling and welding the mouthpiece body 15 and the welding spring 16, the side push plate 13 is used for fixed positioning, and the mouthpiece body 15 and the welding spring 16 are restricted to the corresponding positions. Welding columns 19 are set to perform multi-directional synchronous welding.

[0036] Specifically, before assembling and welding the mouthpiece body 15 and the welding spring 16, the actuating block 7 is moved inside the actuating groove 11, thereby causing the sliding pressing block 6 to slide inside the sliding groove 5. This causes the inclined groove inside the sliding pressing block 6 to press the limiting post 9, which in turn causes the pre-positioning clip 8 to slide and adjust accordingly inside the positioning plate 2. When the pre-positioning clip 8 slides and adjusts, it will pre-position the mouthpiece body 15. At this time, the mouthpiece body 15 is placed inside the assembly positioning block 12, and is in pre-position. After clamping, the side push plate 13 is pressed inward to achieve a fastening effect. Then, the welding spring 16 is assembled on the corresponding welding position of the mouthpiece body 15. Multiple welding pillars 19 set on the outside of the connector 17 can perform multi-directional synchronous welding on the welding positions of the mouthpiece body 15 and the welding spring 16. During welding, the ventilation pipe 20 is connected to the ventilation plate 18 at the bottom of the mouthpiece body 15 for ventilation, cooling and smoke exhaust. This can avoid certain errors in the product when it is reorganized later, and further improve the product quality.
