Abstract

The invention discloses a welding fixture of a frame and a welding method. The welding fixture comprises a first rotational positioning device and a second rotational positioning device. The first rotational positioning device comprises a first connecting disc, a first bearing seat, a first limiting plate, a first connecting lug, a first screw, a first pressing block and a first nut. The second rotational positioning device comprises a second connecting disc, a second bearing seat, a second limiting plate, a second connecting lug, a second screw, a second pressing block and a second nut. The welding method includes the step that the fixture is used for welding a single longitudinal beam and the frame. The welding fixture and the welding method can be suitable for welding of the single longitudinal beam and suitable for welding of the frame.

Description

technical field [0001] The invention relates to a welding tool for a vehicle frame and a method for welding a vehicle frame by using the tool. Background technique [0002] The frame is one of the core components of the car. The current frame is basically formed by welding. Therefore, the quality of the welding of the frame directly affects the quality of the car and the installation of other components. [0003] The existing frame welding basically uses tooling to realize positioning welding. For example, a new type of multi-model vehicle frame flexible flip fixture is disclosed in the patent document of Chinese Patent Application No. 201010582989.3. The automatic flip device bracket is fixedly connected with a support and the bearing seat, one end of the turning shaft is connected to the drive motor through the support and the bearing seat, and the other end is connected to the turning frame; the follower bearing seat, follower support and anti-return wheel are fixed on th...
