Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a feeding finishing 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 and processing of inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads, and can perform grooving, drilling, reaming, reaming and boring, etc. CNC machine tools automatically process the parts to be processed according to the pre-compiled processing program. We compile the processing route, process parameters, tool movement trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then record the contents of this program sheet on the control medium, and then input it into the CNC device of the CNC machine tool, so as to command the machine tool to process the parts.

[0003] The existing CNC lathe feeding finishing is mostly done by manually operating a crane to lift the workpiece and then place it into the machine tool, which is both time-consuming and labor-intensive, and can easily hit the machine tool if not operated properly, causing damage to the machine tool and reducing its service life.

Under the action of the first drive motor, the drum rotates to make the workpiece fall from the discharge port to the second circular groove. Under the action of the second drive motor, the first reciprocating screw drives the push plate to push the workpiece into the machine tool. This solves the problem that the existing feeding and finishing mechanism for CNC lathes is mostly carried out by manually operating the crane to hoist the workpiece and then place it into the machine tool, which is manpower and time-consuming, and is easy to hit the machine tool and cause damage to the machine tool when operated improperly.
