Problems solved by technology

[0002] Nowadays, ordinary machine tools can only process holes with a diameter of less than 8 meters. It is not so easy to process holes with a diameter greater than 8 meters. The processing cost is reduced, and if a workpiece with a slightly more complicated shape is to be processed, ordinary extra machines cannot be clamped at all.

specific Embodiment approach

[0017] A specific implementation of the large-scale steel structure rotary hole processing method of the present invention comprises the following steps:

[0018] A. Assembling the rotary machine tool: the rotary machine tool is refitted from a super large rotary bearing. The rotary bearing equipped with the inner ring gear is removed, installed in a matching drum, and then equipped with a pinion, a reducer, a gearbox and a motor. The internal teeth of the bearing are 56, the matching pinion is 11 teeth, the diameter of the rotary machine tool is 1.85 meters, the height of the drum is 0.9 meters, the total height is 1.05 meters, the reduction ratio of the reducer is 1:50, and there are 5 gearboxes Gear position, adjust different speeds according to the size of the processed hole, both the reducer and the motor are equipped with pulleys, and the torque is transmitted by the belt, equipped with pulleys of different sizes to achieve different rotation speeds, the power of the moto...

Description

Technical field: [0001] The invention relates to a method for machining a large steel structure revolving hole. Background technique: [0002] Nowadays, ordinary machine tools can only process holes with a diameter of less than 8 meters. It is not so easy to process holes with a diameter greater than 8 meters. The processing cost is reduced, and if a workpiece with a slightly more complex shape is to be processed, ordinary extra machines cannot be clamped at all. Invention content: [0003] The purpose of the present invention is to overcome the above disadvantages and provide a large-scale steel structure rotary hole machining method capable of machining inner circles with a diameter of less than 15 meters, high cutting precision, simple operation and cost saving. [0004] The purpose of the present invention is achieved through the following technical solutions: a large-scale steel structure rotary hole processing method, comprising the following steps: [0005] A. Ass...
