Soldering positioning and detecting device

The utility model relates to a tin soldering positioning and detecting device, which comprises a positioning main body and at least one fixing groove arranged on the positioning main body, and integrates detecting and positioning functions by arranging the positioning main body, a compression spring, an adjustable screw, a testing device, a positioning screw and the like. After the tin soldering process is completed, the internal resistance value is directly detected on the positioning and testing device, so that time and labor are saved; the component assembling positioning hole is used as a positioning reference, the positioning screw is used for fixing, the compression spring is used for further abutting against the two sides of the component, positioning is reliable, clamping and disassembling are convenient, the position of the component does not need to be corrected repeatedly in the welding process, and the risks of hand scalding and component scalding are eliminated; and after tin soldering is complet
