Technical Field

[0001] The utility model relates to the technical field of external cylindrical rough turning, in particular to an external cylindrical rough turning device. Background Art

[0002] A lathe is a machine tool that mainly uses a turning tool to turn rotating workpieces. The function of a lathe is to cut rotating surfaces of various sizes, shapes, and spiral surfaces. At present, most shaft processing uses a lathe to rough-turn the outer diameter of the blank. The blank is placed in the three-jaw chuck of the lathe and clamped. The rotational motion transmitted from the main motor in the spindle box passes through a series of speed change mechanisms to enable the spindle to obtain the required forward and reverse rotation speeds. At the same time, the spindle box allocates part of the power to transmit the motion to the three-jaw chuck, causing the blank in the three-jaw chuck to rotate. The turning tool mechanism moves longitudinally, horizontally or obliquely to rough-turn the outer diameter of the rotating blank.

[0003] When processing large cylindrical workpieces, it is inconvenient to calibrate them horizontally. It is necessary to repeatedly calibrate the level using lifting tools, which is time-consuming and labor-intensive, and also has certain risks. Therefore, we propose an external cylindrical rough turning device to solve the above problem. Utility Model Content
