AI Technical Summary

Problems solved by technology

[0006] For the design of processing technology equipment and corresponding cooling and lubrication systems for large aviation aluminum alloy workpieces and similar workpieces, researchers have made great progress. At present, many designers have designed related fixtures and process equipment in related fields. It solves the problems in the processing of workpieces such as low positioning accuracy, high labor intensity, and low production efficiency. However, for large workpieces, due to the large size and weight of the workpiece, unreliable clamping is prone to occur during processing.

Moreover, there are many minimal quantity lubrication devices designed by designers, which have made outstanding contributions in terms of resource saving and lubrication performance. However, the compatibility with fixtures is low, and there is no good combination with the process equipment of fixtures.

The atomizing nozzle of the minimum quantity lubrication device is generally suspended on the side of the machine tool spindle, which requires a large movement space during processing

Moreover, due to the consideration of workpiece structure and workpiece clamping requirements, some parts of the fixture may be higher than the surface of the workpiece, so the nozzle is likely to interfere with the fixture, causing equipment damage
