Detailed Description
It is right to combine specific embodiment below the utility model discloses a prevent that solder joint warp anchor clamps structure does further explanation to help technical staff in this field to be right the utility model's technical scheme has more complete, accurate and deep understanding.
Example 1
As shown in fig. 1, the clamp structure for preventing deformation of a welding spot according to the present embodiment includes a plastic connecting block 10, a copper pad 30, and a pressing arm 60, where the plastic connecting block 10 includes a pressing plate 11 and a side connecting block 12 located on the pressing plate 11, and the pressing plate 11 and the side connecting block 12 are an integrally formed structure. The side wall of the pressing arm 60 is tightly connected to the side connection block 12 by a first bolt 50, and the first bolt 50 is preferably two and is disposed at both ends of the side connection block 12. The copper pad 30 comprises a pad bottom plate 31 and a bump 32 located on the pad bottom plate 31, wherein the bump 32 extends along the length direction of the pad bottom plate 31. The pad base plate 31 and the projection 32 are integrally formed. The upper surface of the projection 32 is opposite to the lower surface of the pressing plate 11, two second bolts 40 are arranged between the pressing plate 11 and the projection 32, a spring 20 is arranged on a screw rod of the second bolt 40 between the lower surface of the pressing plate 11 and the upper surface of the projection 32, and the two second bolts 40 are arranged at intervals in the length direction of the pressing plate 11.
Fig. 2 shows the application view of the fixture structure for preventing deformation of the welding spot in the embodiment, the end of the pressing arm 60 of the fixture is connected with power mechanisms such as cylinders, and pressure is applied, so that the copper pad block 30 can be fully attached to the metal plate welding surface through the elastic force of the spring 20, the plastic connecting block 10 is made of insulating plastic, and thus shunting can be prevented, the plastic connecting block 10 is connected with the pressing arm 60 through bolts, the fixture structure for preventing deformation of the welding spot in the embodiment can ensure that the copper pad block 30 is fully attached to the welding surface to reduce welding deformation, the appearance of the welding spot is effectively ensured to be smooth and attractive, the defective percentage is reduced, and the repair caused by the welding spot is.
For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements are all within the protection scope of the present invention as long as the technical solution of the present invention is adopted.
