Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a loading and unloading mechanism for 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 inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads. It can also perform grooving, drilling, reaming, reaming and boring, etc. When processing mechanical parts, it is necessary to perform loading and unloading operations on it.

[0003] When loading and unloading materials, existing CNC lathes usually use pneumatic clamps to clamp materials, etc., which makes the pneumatic clamps not precise enough, resulting in the clamping force of the clamps on the materials becoming loose, which in turn causes the materials to fall during loading and unloading. At the same time, existing CNC lathes usually process both sides of the materials, making it impossible to complete the processing of multiple surfaces of the materials, thereby reducing the utilization efficiency of existing equipment.
