Problems solved by technology

Due to the special shape of the large crankshaft, it is not easy to fix it. If it is directly clamped on the lathe for processing, not only will there be indentations on the surface of the workpiece, which needs to be repaired later, but also the clamping speed is slow, and the processing accuracy cannot meet the requirements.
If a special lock sleeve is used for clamping, since the lock sleeve is more expensive, and one lock sleeve can only install a workpiece of one specification, since there are many workpiece specifications, multiple lock sleeves need to be prepared, which will greatly increase the production of the enterprise. cost

Description

technical field [0001] The invention relates to a fixture in the technical field of large crankshaft processing, in particular to a special clamping device for large crankshaft eccentricity. Background technique [0002] When the large crankshaft of the compressor is turned and turned, in order to ensure the product quality, the precision of the workpiece clamping is very high. Due to the special shape of the large crankshaft, it is not easy to fix it. If it is directly clamped on the lathe for processing, not only will there be indentations on the surface of the workpiece, which needs to be repaired later, but also the clamping speed is slow, and the processing accuracy cannot meet the requirements. If a special lock sleeve is used for clamping, since the lock sleeve is more expensive, and one lock sleeve can only install a workpiece of one specification, since there are many workpiece specifications, multiple lock sleeves need to be prepared, which will greatly increase th...
