Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a protective device for a lathe used for mechanical processing. Background Art

[0002] Lathe processing is a part of mechanical processing. There are mainly two types of processing. One is to fix the turning tool and process the unformed workpiece during rotation. The other is to fix the workpiece and perform precision processing through high-speed rotation of the workpiece and lateral and longitudinal movement of the turning tool.

[0003] Although the protective devices used in the existing mechanical processing lathes can achieve the protective effect, it is very cumbersome to perform protection during lathe processing, resulting in low work efficiency and the inability to observe the internal situation during processing. In addition, the lathe will produce a large amount of iron filings and impurities during the processing. These impurities can easily fall into the protective device and the lathe, making it inconvenient for the staff to clean them, causing many inconveniences to the staff. For this reason, we propose a protective device for a mechanical processing lathe to solve the above problems. Utility Model Content
