Turning tool for machining inner hole of thin-wall part

Abstract

The invention discloses a turning tool for machining an inner hole of a thin-wall part. The turning tool for machining the inner hole of the thin-wall part is characterized by comprising a connecting disk and a press plate, the axis of the connecting disk and the axis of a locating disk are arranged on the same straight line, the right portion of the connecting disk is fixedly connected with the left portion of the locating disk, and a locating spigot is formed in the right end of a center hole of the locating disk; and two to four air cylinders are arranged between the connecting disk and the locating disk in the circumferential direction, piston rods of the air cylinders are parallel to the axis of the locating disk, and cylinder bodies of the air cylinders are fixedly connected with the outer wall of the locating disk; the number of the press plate is one, a lathe tool receding hole is formed in the center of the press plate, and connecting screws are fixedly connected with the right ends of the piston rods of the corresponding air cylinders after penetrating through threaded installing holes formed in the press plate. According to the turning tool for machining the inner hole of the thin-wall part, due to the facts that locating is carried out on the outer circle surface of the thin-wall part, and the end face of the thin-wall part is tightly pressed through the air cylinders and the press plate, the side wall of the thin-wall part cannot bear radial force, deformation, in the radial direction, of the thin-wall part is avoided, and then the roundness of the inner hole of the thin-wall part is ensured.

Description

technical field [0001] The invention belongs to the field of tool fixtures, and in particular relates to a vehicle tool used for processing inner holes of thin-walled parts. Background technique [0002] In the field of mechanical engineering, thin-walled parts (ie figure 1 The workpiece G) in is a widely used component, and the inner hole of the thin-walled part often needs to be turned. At present, the outer circular surface of the thin-walled part is generally clamped by a conventional three-jaw chuck, and then the inner hole of the thin-walled part is processed by a turning tool. [0003] The defect of the existing processing method is: because the thickness of the thin-walled part is relatively thin, it is easy to deform after being clamped by the three-jaw chuck, so that it is difficult to ensure the roundness of the inner hole of the thin-walled part. Therefore, it is urgent to solve the above technical problems. Contents of the invention [0004] The technical pr...
