Description

Technical Field

[0001] The utility model relates to the technical field of crane manufacturing, in particular to a positioning device for manufacturing crane accessories. Background Art

[0002] A crane is a multi-action lifting machine that can lift and carry heavy objects vertically and horizontally within a certain range. It is also called an overhead crane, an overhead crane, a crane, or a tire crane. Its main features are: its driving cab and the lifting control cab are combined into one, and it is evolved from a crawler crane (crawler crane). The crawler and the traveling support part of the traveling mechanism are transformed into a chassis with tires, which overcomes the disadvantage of the crawler plate of the crawler crane (crawler crane) causing damage to the road surface. It belongs to material handling machinery. When producing cranes, some steel plates need to be drilled, so positioning equipment for the production and manufacturing of crane accessories came into being. Since the sizes of crane accessories are different, it is necessary to position steel plates of different sizes.

[0003] A positioning device for the production and manufacturing of crane parts is disclosed in the Chinese utility model patent application disclosure CN216442401U. Although the utility model can enhance the firmness of the clamping of steel plates and reduce the anti-falling property of steel plates, the utility model cannot clamp steel plates of different sizes and thicknesses during the process of clamping the steel plates, which reduces the practicality of the device. Therefore, there is a problem that steel plates of different sizes and thicknesses cannot be clamped. In addition, the utility model cannot position steel plates of different sizes during use, has a small scope of application, and is used singly. Therefore, there is a problem that steel plates of different sizes cannot be positioned. In summary, the utility model has the problem that steel plates of different sizes and thicknesses cannot be clamped and cannot be positioned. Utility Model Content
