[0016] Please refer to Figure 1-2 , the present utility model provides a technical solution: an auxiliary welding jig for chip components, including a working platform 1, two support rods 2 are installed on the working platform 1, a clamping block 3 is rotatably installed on the support rods 2, and a limiting assembly for restricting the rotation of the clamping block 3 is installed on one of the support rods 2;

[0017] The limiting assembly includes a limiting rod 4 installed at the rotational connection between the clamping block 3 and the support rod 2, and a socketing assembly 5 is installed on the outer side wall of the support rod 2. The flipping of the clamping block 3 is realized through the socketing or separation of the socketing assembly 5 and the limiting rod 4.

[0018] The upper and lower end faces of the limiting rod 4 are flat.

[0019] The socket assembly 5 includes a limiting frame 51. A limiting block 52 sleeved on the limiting rod 4 is slidably arranged in the limiting frame 51. A screw rod 53 is screwed at the end of the limiting frame 51. The screw rod 53 is rotatably connected to the limiting block 52.
