Description

Technical Field

[0001] The utility model relates to the technical field of tow trucks, in particular to a positioning fixture for a flat-plate bracket of a tow truck. Background Art

[0002] The tow truck has the function of moving faulty vehicles and illegal vehicles in the city. By connecting the broken-down or accident car to the rear supporting arm of the tow truck, the accident vehicle can be towed onto the flatbed of the tow truck. In the manufacturing process of the tow truck, a bracket needs to be welded under the flatbed of the tow truck. On the one hand, the structural strength of the flatbed can be improved, and on the other hand, the flatbed is fixed to the vehicle body with the help of the bracket. The bracket mainly includes two longitudinal beams and multiple cross beams welded together. Now the bracket generally directly puts the longitudinal beams and cross beams on the ground for assembly. Since there is no positioning fixture to fix them, the longitudinal beams and cross beams can only be placed in a relatively suitable initial assembly position based on assembly experience. Frequent adjustments are required later to ensure that the two longitudinal beams are parallel to each other and the cross beams are perpendicular to each other. In addition, the bracket is easy to shake during welding, resulting in the offset of the weld point, which affects the overall structural strength of the bracket. Therefore, a positioning fixture for the tow truck flatbed bracket is needed.

[0003] The existing flatbed bracket positioning fixture for a tow truck has the problems of poor fixing effect, inability to prevent deviation, and inability to adjust the position during operation. Therefore, a flatbed bracket positioning fixture for a tow truck is urgently needed. Utility Model Content
