Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be further described in detail below with reference to the accompanying drawings and examples of the present utility model. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

On the contrary, the utility model is intended to cover any alternatives, modifications, equivalents, and variations as may be included within the spirit and scope of the utility model as defined by the appended claims. Further, in the following detailed description of the present utility model, certain specific details are set forth in order to provide a better understanding of the present utility model. The present utility model will be fully understood by those skilled in the art without the details described herein.

Referring to fig. 1-5, a welding jig for mobile phone accessories comprises a base 1 and a pressing block 2, wherein the base 1 and the pressing block 2 are connected through a connecting block 3.

Specifically, the middle part of base 1 is equipped with welding station 9, installs a plurality of locating pins 901 on the welding station 9, is equipped with on button and the piece that waits to weld with locating pin 901 assorted locating hole to wait to weld the placing of piece and provide preliminary location.

Specifically, a positioning groove 101 is formed in one side of the base 1, located at the welding station 9, a reference plate 4 is arranged in the positioning groove 101 in a matched mode, and one side of the reference plate 4 is in contact with a piece to be welded.

Specifically, three grooves 102 are formed in the other side of the base 1, which is located at the welding station 9, a side pressing plate 5 is arranged in each groove 102, the three side pressing plates 5 are connected to form a whole through connecting rods 6, each side pressing plate 5 comprises a side pressing section 501 and a connecting section 502, and the connecting rods 6 penetrate through the connecting sections 502 on the three side pressing plates 5 and can be rotatably arranged in the base 1 in a penetrating mode.
