Description

Technical Field

[0001] The utility model relates to the technical field of turning, in particular to a numerically controlled thread processing lathe. Background Art

[0002] CNC thread processing lathe is mainly used to process various types of threads, such as internal thread, external thread, coarse thread, fine thread, precision thread and left-hand thread, etc. It uses the CNC system to accurately control the movement of each axis of the machine tool to achieve high-speed, high-precision and multi-functional processing operations.

[0003] The utility model with the authorization publication number CN216575919U provides a CNC thread processing lathe, which belongs to the field of "turning" technology. The protected claim: "It includes a workbench and a base. A first hydraulic rod is welded and installed on the inner wall of the rear side of the base, and a tool holder is slidably installed on the inner bottom of the base. The free end of the first hydraulic rod is welded and installed with the rear side wall of the tool holder. A thread turning tool is arranged on the top of the tool holder, and a fixed plate is welded and installed on the top of the workbench. The depth of the workpiece turned by the thread turning tool is controlled by the first hydraulic rod, so as to facilitate the control of the thread depth. The threaded rod is driven to rotate by the motor, and the threaded rod is engaged with the base to realize the uniform lateral movement of the base along the guide rail, thereby realizing the uniform lateral movement of the thread turning tool, and then realizing the opening of threads on the surface of the workpiece. The tap is driven to move horizontally at a uniform speed by the second hydraulic rod so that the tap contacts the inner circle of the workpiece, thereby realizing the opening of internal threads on the workpiece, thereby facilitating the simultaneous processing of internal and external threads on the workpiece and improving work efficiency."

[0004] Although this equipment can turn threads, the iron filings generated in the process of turning external threads will easily affect the quality and efficiency of turning, and even cause damage to the tapping tool if they are not cleaned in time. For this reason, we propose a CNC thread processing lathe. Utility Model Content
