Description

technical field [0001] The invention relates to the technical field of straightening, in particular to a horizontal self-adaptive mechanical precision straightening device and method for straight strips. Background technique [0002] Precision linear strip is one of the core components of mechanical equipment. Its straightness error directly affects the working accuracy of mechanical equipment, especially when it is used as a straight line reference for the relative position and movement of the main functional components of mechanical manufacturing equipment, its accuracy directly affects the mechanical manufacturing equipment. The mutual positional relationship between the forming movements, and then affect the product processing accuracy of the entire manufacturing equipment. The straightening of straight strips is one of the important processes to ensure the straightness processing quality of straight strips. The level of processing accuracy determines the processing allo...

Problems solved by technology

Since the screw loading system and measuring system are installed on the axially movable carrier, and the carrier is installed on the guide column, the straightness error of the guide column is directly added to the straightening error, and at the same time, the rigidity of the guide column is limited. , and the rigidity of the ball screw is small, and the deformation during loading is large, which is not suitable for straightening processing of workpieces with high rigidity. In addition, the length of the guide column is limited, and the length of the workpiece that can be straightened is limited.

[0005] In order to overcome the shortcomings of the above-mentioned straightening device, such as low rigidity, low straightening accuracy, and limited length of straightened workpieces, it is necessary to provide a new type of straightening equipment for straight strips.
