[0030] See also Figure 1-Figure 6 As shown, a multifunctional fixture for filter debugging welding includes a frame 2 made of synthetic stone, a welding plate 4 made of synthetic stone and a debugging plate 1. The frame 2 is provided with a cavity for fixing a product 5, positioning pin holes 23 are provided at both ends of the frame 2, and a debugging hole for locking an inter-adjustment fixed joint 3 is provided on one side of the frame 2.
[0031] In this embodiment, the frame 2 is composed of a U-shaped plate 21 and a panel 22 according to different uses. When used in conjunction with the debugging pressure plate 1, the frame 2 is provided with a U-shaped plate 21 and a panel 22. The panel 22 is arranged on the outer side of the U-shaped plate 21, and a debugging hole is provided on the panel 22.
[0032] When used together with the welding pressure plate 4 , the surrounding frame 2 is composed of a U-shaped plate 21 and a panel 24 . The panel 24 is arranged on the outer side of the U-shaped plate 21 . The panel 24 is provided with a debugging hole 242 and a card slot 241 .
[0033] The panels 22 and 24 are both bolted to the U-shaped plate 21. On-site personnel can easily replace the panels according to actual use, and the operability is strong.
[0034] In this embodiment, the upper and lower end surfaces of the U-shaped plate 21 are both provided with openings for exposing the welding area of the product 5, and the two openings have the same structure; the U-shaped plate 21 at the outer sides of the two openings is provided with positioning pin holes 23 adapted to the welding plate 4 and the debugging plate 1. With the above structure, there is no need to distinguish the front and back sides of the U-shaped plate 21, which improves the convenience of operation.
[0035] Of course, in addition to the openings on both sides of the U-shaped plate 21 in this embodiment, the U-shaped plate 21 may also have an opening on only one side. For example, the upper end surface of the U-shaped plate 21 is provided with an opening that exposes the welding area of the product 5, and the positioning pin holes 23 are located on both sides of the opening.
[0036] In this embodiment, the frame 2 is made of synthetic stone material, which is resistant to high temperature and not easy to deform. The U-shaped plate and the panel are assembled, and the positioning pin holes at both ends of the U-shaped plate can realize the precise fixation of the cavity. The panel is provided with a debugging hole for passing the debugging cable connector.
[0037] In this embodiment, the welding platen 4 includes a welding base plate 41, on which a positioning pin 44 corresponding to the positioning pin hole is provided, and a plurality of spring pins 43 are provided on the welding base plate 41, and the spring pins 43 correspond to the welding parts on the product 5. A plurality of clamping parts 42 are symmetrically provided on both sides of the welding base plate 41, and the clamping parts 42 have hooks. A card slot 241 is provided on the corresponding panel 24, and the hooks on both sides of the welding platen 4 are sequentially clamped in the card slot 241 and the notch of the U-shaped plate, and are used in conjunction with the positioning pin 44, so that the welding platen 4 can be stably installed on the enclosure 2. A debugging hole 242 is provided on the welding base plate 41 for the installation of the inter-adjustable fixed joint 3.
[0038] In this embodiment, the welding pressure plate 4 is made of synthetic stone material, and spring pins corresponding to the welding positions are arranged on it to play the dual role of limiting the pressing connection and precise positioning.
[0039] In this embodiment, the debugging platen 1 includes a debugging substrate 11. The edges of the debugging substrate 11 are provided with screw holes. Bolts can pass through the screw holes to lock the debugging platen 1 on the enclosure 2. The middle area of the debugging substrate 11 is the working area. After installation, the above working area is pressed on the product. The debugging substrate 11 located outside the working area is provided with positioning pins 12. The above positioning pins 12 correspond to the positioning pin holes 23 on the enclosure 2. This allows the debugging platen 1 to be stably installed on the enclosure 2.
[0040] In this embodiment, the debugging pressure plate 1 is made of SUS304 stainless steel, which has good flatness, high hardness and is not easy to deform. It is covered with a silicone coating. After being tightened with screws, the cover plate and the cavity can fit tightly, so that the required electromagnetic shielding effect is formed in the cavity.
[0041] The multifunctional clamp provided by the utility model has the following steps for use:
[0042] (1) Place the product cavity for debugging in the frame and screw it in.
[0043] (2) During the welding process, a welding pressure plate is used to fix the cover plate to the frame through the clamps on both sides of the cover plate, so that the spring pins on the welding pressure plate can accurately position and press each welding component together for melting and welding through welding technology equipment.
[0044] During the debugging process, the debugging pressing plate 1 can be used to fix it on the surrounding frame by screws, and quick debugging can be performed through the debugging holes reserved on the pressing plate 22.
[0045] (3) During intermodulation, use the intermodulation fixed connector 3 to lock it on the hole (debugging hole) reserved on the panel of the enclosure, and then connect the intermodulation test cable.
[0046] The disassembly process is logically consistent with the installation process and will not be elaborated here. This tooling is small in size, can be rotated and flipped at any angle on both sides without restriction, and can be tightened and disassembled quickly.
[0047] This fixture is multifunctional. As the application scenario and external dimensions of the filter change, the application scenario, material, external shape, positioning structure, and some components will change.
[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
