Large-scale work piece plane coping automatics

Technical Field

The invention relates to the field of workpiece grinding, in particular to an automatic plane grinding device for a large-sized workpiece.

Background

Common methods for machining include turning, milling, grinding, polishing and other cutting processes. At present, the machined plates of companies are sufficiently reserved on turning and milling equipment, and a workshop numerical control lathe and a boring and milling machine are in the mainstream level of the industry in terms of equipment quality and equipment maintenance. However, in the grinding and polishing process, the workshop equipment is usually very weak, the inner hole is usually ground by a honing machine, the maximum processing diameter is smaller, and a grinding machine used for grinding the surface can only grind workpieces with smaller length.

For the grinding processing of large-sized workpieces, two methods are adopted in a workshop at present, one is that the traditional manual grinding is adopted, namely, workers repeatedly grind the workpieces by using a grinding machine, thus wasting time and labor and easily causing occupational diseases due to dust problems; the other method is to modify the existing lathe equipment (such as a 5-meter vertical lathe, a numerical control gantry mill and the like) through a self-made tool, so that although the production problem can be solved, the equipment is greatly damaged by the operation of finishing rough machining by using fine machining equipment, and the machining precision of the equipment is seriously reduced by dust and high-frequency vibration in the past.
