Description

Technical Field

[0001] The utility model relates to a welding positioning tool technology, in particular to a threaded seat, a nut plate and a nut positioning tool. Background Art

[0002] There are several types of threaded seats, nut plates and nuts that need to be installed on the existing frame platform. The threaded seats, nut plates and nuts on the frame platform are used to install the locking devices of various mechanisms, walkways and covers on the platform, and are used in conjunction with bolts. The threaded seats, nut plates and nuts are installed below the bottom hole. When installing the threaded seats, nut plates and nuts, it is necessary to ensure that the center of the threaded hole is coaxial with the center of the bottom hole before welding and fixing.

[0003] However, the current welding method has the following problems: Since the threaded hole needs to be positioned based on the mounting hole, and in order to reduce manufacturing errors, the mounting hole is usually 2mm larger than the threaded hole. For example, the M12 thread generally uses a mounting bottom hole with a diameter of 14. If the threaded seat, nut plate and nut are directly installed below the bottom hole, or the bolt positioning installation method is directly used, there will be the disadvantage that the center of the threaded hole and the center of the bottom hole are not coaxial; and there will be multiple mounting holes in the same plane for mounting components, and multiple mounting holes have a relative size relationship. If they are directly installed, cumulative errors will also occur, which will eventually lead to the inability to install the components on the platform. Utility Model Content
