Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frame correction, in particular to a vehicle frame assembly correction device. Background Art

[0002] The frame assembly is a part of the vehicle body structure. It cooperates with the vehicle body to form the structural frame of the vehicle. The frame assembly is welded together by two main units: the front frame and the rear frame. The front frame is welded by several small parts such as the left and right channel beams, the front vertical plate, the front and rear mounting seats of the front axle, and the transverse connecting plate. The rear frame is welded by several parts such as the left and right brackets, the rear axle mounting plate, the lifter mounting panel, the rear panel, and the vertical plate. The function of the frame assembly is to bear the weight of the vehicle body and various loads to ensure the stability and safety of the vehicle body.

[0003] The frame may be deformed due to various reasons during the manufacturing, transportation or use process, resulting in the geometric shape not meeting the requirements. The deformation of the frame may affect the driving stability, handling and comfort of the vehicle.

However, the correction device of the existing frame assembly does not have the function of automatically adjusting the correction position.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, in order to compensate for the defect that the frame in the first embodiment is easily deflected during the correction process, four clamping mechanisms 200 are fixedly connected to the top surface of the base 110 to achieve the effect of enhancing the stable fixation of the frame.

The movable clamp block 230 can be fitted to the frame by screwing the two adjustment knobs 260, so that the movable clamp block 230 and the fixed clamp block 220 clamp the frame. The anti-slip rubber layer can increase the friction between the fixed clamp block 220 and the movable clamp block 230 and the frame to prevent the frame from shifting during the correction process. By providing four clamping mechanisms 200, it is easy to adapt to frame assemblies of different sizes, and at least two positions can be corrected at the same time, which greatly improves work efficiency.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
