Description

Technical Field

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

[0002] CNC lathe is one of the most widely used CNC machine tools at present. 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 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 motion 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 parts. When CNC lathes process parts, they often need to drill holes in the parts, and then use drilling sandwiches.
