Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to a shielding cover welding fixture. Background Technology

[0002] Shielding covers are widely used in electronic equipment. They can effectively isolate the electromagnetic radiation generated by electronic equipment during operation, preventing it from interfering with other circuits or systems. They can also resist interference from external electromagnetic signals, ensuring the stable operation of the equipment.

[0003] like Figure 1 As shown, traditional shielding covers typically consist of a metal housing to achieve the shielding function. This metal housing is usually directly stamped. Within the confined space of the metal housing, to reduce interference between different electronic components within the same shielding cover, metal partitions are needed to divide the area into different zones. These metal partitions cannot be directly formed through the initial stamping process and require subsequent welding. During welding, the metal housing is generally fixed to a welding fixture, and then the metal partitions need to be positioned in their predetermined positions on the metal housing before welding. Currently, after welding, the shielding cover needs to be removed from the welding fixture. Some methods involve prying the shielding cover off the fixture, which can easily damage it. Other methods involve flipping the entire welding fixture over to pour out the shielding cover. These methods are inefficient, time-consuming, labor-intensive, and prone to damaging the shielding cover, failing to meet the welding requirements for shielding covers. Utility Model Content

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0031] like Figure 2-6 The image shows a welding fixture for a shielding cover 3 according to this embodiment. The shielding cover 3 includes a cover body 31 and a welding body 32. Both the cover body 31 and the welding body 32 are made of metal. The welding body 32 is a long strip plate structure that can be welded onto the cover body 31 to divide the interior of the cover body 31 into different areas. The welding fixture includes a fixing plate 1 and a stripping plate 2. Both the stripping plate 2 and the fixing plate 1 are plate structures. The stripping plate 2 can be stacked on the fixing plate 1, so that the stripping plate 2 is in a coupled state placed on the fixing plate 1. By lifting the stripping plate 2 upwards, the stripping plate 2 is in a separated state away from the fixing plate 1.

[0032] The stripper plate 2 has several positioning areas arranged on its surface. Each positioning area has several through holes 22 penetrating the stripper plate 2. These positioning areas are adapted to the cover 31 of the shielding cover 3, such that the cover 31 is placed within the positioning area and its movement in its length and width directions is restricted to a first positioning state. In this embodiment, a positioning groove 21 adapted to the cover 31 is machined on the stripper plate 2. This positioning groove 21 encloses the aforementioned positioning area, allowing the cover 31 to be placed into it. The surrounding sides of the cover 31 contact the inner peripheral wall of the positioning groove 21, thus restricting its movement and completing the positioning of the cover 31 on the stripper plate 2.

[0033] A positioning pin 11 is fixedly installed on the aforementioned fixing plate 1 corresponding to each through hole 22. The positioning pin 11 is vertically fixed on the fixing plate 1. When the stripper plate 2 is in the aforementioned combined state, the positioning pin 11 is inserted into the through hole 22 at the corresponding position and extends into the positioning groove 21.

[0034] The aforementioned cover 31 has clearance holes machined on a plurality of positioning pins 11. These clearance holes penetrate the cover 31. Similarly, the welded body 32 has positioning holes machined on a plurality of positioning pins 11, these positioning holes penetrating the welded body 32. When the stripper plate 2 is in the aforementioned combined state and the cover 31 is in the aforementioned first positioning state, the clearance holes and the corresponding positioning pins 11 form an interlocking engagement, and the welded part has a second positioning state in which the positioning holes and the corresponding positioning pins 11 form an interlocking engagement. In this second positioning state, the welded body 32 is positioned by the engagement of the positioning holes and the positioning pins 11, thereby enabling the welded body 32 to be positioned at a preset position on the cover 31.

[0035] In the specific structural design, the diameter of the aforementioned through hole 22 is larger than the outer diameter of the positioning pin 11, allowing the positioning pin 11 to smoothly enter and exit the through hole 22. Similarly, the diameter of the aforementioned clearance hole is larger than the outer diameter of the positioning pin 11, allowing the positioning pin 11 to smoothly enter and exit the clearance hole. In this embodiment, the diameter of the clearance hole is matched to the outer diameter of the positioning pin 11, creating a clearance fit when the clearance hole and the positioning pin 11 are inserted. This allows for secondary positioning of the cover 31, resulting in accurate and reliable positioning of the cover 31.

[0036] The number of the aforementioned welded bodies 32 is two or more, depending on the actual design. Positioning pins 11 are arranged corresponding to the positioning holes on each welded body 32, thereby enabling the positioning of each welded body 32.

[0037] In this embodiment, positioning posts 12 are distributed and installed on the aforementioned fixed plate 1. Guide holes 23 are machined on the stripping plate 2 corresponding to the positioning posts 12. When the stripping plate 2 is placed on the fixed plate 1, the positioning posts 12 are inserted into the guide holes 23, and the two form a clearance fit to position the stripping plate 2 on the fixed plate 1. A recessed space 13 is machined on the side of the fixed plate 1. A gripping edge is formed on the stripping plate 2 corresponding to the recessed space 13. The operator's hand can reach into the recessed space 13 and grip the gripping edge of the stripping plate 2 to move the stripping plate 2.

[0038] In practical use, several shielding covers 31 are placed in the positioning grooves 21 on the stripper plate 2 for positioning and fixing. The guide holes 23 on the stripper plate 2 are aligned with the positioning posts 12, and then the stripper plate 2 is lowered to place it on the fixing plate 1, forming a combined state. Each positioning pin 11 is inserted into the corresponding through holes 22 and clearance holes. The welding body 32 is inserted through the positioning holes onto the positioning pins 11, positioning the welding body 32 on the cover 31, and then welded and fixed to the cover 31. After welding, the stripper plate 2 is lifted upwards, separating the stripper plate 2 and the shielding cover 3 from the fixing plate 1. The welded shielding cover 3 is evenly detached from the positioning pins 11, and the shielding cover 3 is removed by flipping the stripper plate 2. This combination allows for accurate positioning of the shielding cover 3, ensuring accurate and reliable welding. Furthermore, the shielding cover 3 is easy to remove after welding, saving time and effort, and effectively meeting the welding requirements of the shielding cover 3.
