Description

Technical Field

[0001] The present invention relates to the technical field of transformer automated production equipment, and in particular to an automatic numerically controlled lathe for manufacturing transformer parts. Background Art

[0002] A CNC lathe is a mechanical device that uses programmed control to complete part processing in the form of digital instructions. It is also called a machine tool or lathe. In the processing of specific transformer parts, the demand is large, and the processing efficiency of ordinary lathes is relatively low and the labor intensity is high. During processing, the end face of the product is cut and formed at the same time, and then holes are drilled. After the holes are drilled, they are cut again, and the cutting and drilling actions are repeated continuously. The existing automatic CNC machine tools basically meet the demand, but there are still certain shortcomings. The existing CNC machine tools need to stop the spindle before feeding, and the feeding time is long. The spindle chuck of the machine tool needs to stop before it can be automatically clamped or released. At the same time, the feed directions of the machine tool need to be manually operated, the production efficiency is low, and the labor intensity of the workers is high. Therefore, it is very necessary to design an automatic CNC lathe for the production of transformer parts. Summary of the Invention
