Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, and specifically discloses a positioning device for turning a rotary workpiece. Background Art

[0002] Rotating workpieces are parts of various shapes made from cylinders, and their characteristic is that they are symmetrical about the center line of the cylinder. Rotating workpieces are generally made by lathes, and the lathe tool performs cutting processing in a straight or curved motion in a plane. Turning processing is generally performed on lathes to process the inner and outer cylindrical surfaces, end faces, conical surfaces, forming surfaces and threads of workpieces. When turning inner and outer cylindrical surfaces, the turning tool moves in a direction parallel to the axis of rotation of the workpiece. When turning end faces or cutting workpieces, the turning tool moves horizontally in a direction perpendicular to the axis of rotation of the workpiece. If the movement trajectory of the turning tool forms an oblique angle with the axis of rotation of the workpiece, a conical surface can be processed. The forming tool method or the tool tip trajectory method can be used to turn the surface of a rotating body.

[0003] The utility model patent with authorization announcement number: CN210548614U discloses a dividing and rotating device for rotating parts that is convenient to process, including a chassis and a turntable, the turntable is rotatably connected to the upper surface of the chassis, the lower end of the chassis is fixedly connected to a fixed box, a motor is arranged in the fixed box, the output end of the motor is rotatably connected to the rotating shaft, the upper end of the rotating shaft passes through the chassis and the turntable in sequence and the upper end of the rotating shaft is rotatably connected to the turntable, a support frame is arranged on one side of the fixed box, the support frame is a U-shaped structure, the lower end of the upper surface of the support frame is fixedly connected to a hydraulic telescopic column, the lower end face of the hydraulic telescopic column is fixedly connected to a fixed disc, the lower end face of the fixed disc is laterally fixed with at least one electric push rod, and the telescopic end of the electric push rod is connected to a pressure column.

[0004] In the disclosed patent technology, the rotating workpiece is pressed onto the turntable by a fixed disc, and is stably fixed by a fixed block and a pressure column. During the turning process of the rotating workpiece, the position of the rotating workpiece can be adjusted by rotating the turntable to adapt to the lathe. In the actual production process, the dimensions and sizes of rotating workpieces from different batches vary greatly, and threads and grooves of varying depths need to be provided on the inner and outer circumferential surfaces and end surfaces of the rotating workpiece.
