Description
Novel banana sieve processing is with location frock Technical Field The utility model relates to the technical field of mining machinery processing equipment, in particular to a novel positioning tool for banana screen processing. Background The banana screen is used as large-scale vibration screening equipment, and the banana screen surface is of a banana-shaped bending structure, so that the banana screen is widely applied to material classification operation in industries such as mines, metallurgy and the like. The screen body is usually formed by welding and assembling a plurality of sections of arc-shaped screen plates, and has the characteristics of large volume, large weight and complex structure. In the processes of hole making, welding and assembling of the screen body, the position precision and geometric dimensions (such as flatness, perpendicularity and radian consistency) of each part are required to be ensured to meet the design requirements, otherwise, the vibration performance, the service life and the screening efficiency of the screen body are directly affected. The technical problem of insufficient positioning precision commonly exists in the traditional banana screen processing technology. The traditional frock adopts fixed supporting shoe or simple and easy frame construction more, is difficult to adapt to the complicated curved surface characteristic of banana screen frame, and the part easily takes place three-dimensional space skew when leading to welding or equipment, causes the accumulative error to show the increase.
