Simple device for large steel structure piece hole machining

Abstract

The invention discloses a simple device for large steel structure piece hole machining. Evenly-distributed tightening threaded holes are formed in a boring rod for installing a tool I. A center through hole of a supporting base is internally provided with a copper sleeve which is in cup joint with the boring rod, an end cover and an adjusting sleeve, and boring rod position adjusting and lubricating can be achieved. A tool rest is divided into an upper part and a lower part and can be fixed to the boring rod, and the tool rest can adapt to installing and adjusting of multiple tools. The provided device is wide in application rage, suitable for multiple indoor and outdoor occasions, low in manufacturing cost, convenient to use and high in efficiency.

Description

technical field [0001] The invention relates to a hole processing device for large steel structure parts, in particular to a simple device for hole processing of large steel structure parts. Background technique [0002] At present, the hinge points of some large-scale equipment need to be bored and milled. Many of the parts where these hinge points are located are large steel structures. The axis and symmetry have precision requirements, and the verticality of the end face also has precision requirements. If the hinge point to be processed is disconnected from the overall steel structure, machined by a boring machine and then welded to the steel structure as a whole, then Welding deformation will affect the accuracy requirements of hinge points. After searching the relevant information, it is found that there is no simple, low-cost, outdoor operation-friendly device that can meet the overall processing of steel structural parts.
