Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for drilling holes in a numerically controlled lathe. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting and processing of inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads. In the process of mechanical manufacturing, CNC lathes are also used for mechanical cutting, milling and drilling. When drilling holes, the material to be processed needs to be fixed before drilling.

[0003] Although the existing CNC lathe drilling fixture can clamp and fix the material, when the CNC lathe drills the material, a large amount of debris will be generated due to the friction between the tool and the material. The debris will have a high temperature due to friction when it is generated, and will be splashed out by the rotating tool. When it comes into contact with the skin of the staff, it will cause skin burns, which is very likely to cause harm to the surrounding staff. Therefore, we propose a CNC lathe drilling fixture.
