Cutting tool for annular outer edge of thin-wall spherical-crown-shaped cover body

Abstract

The invention discloses a cutting tool for an annular outer edge of a thin-wall spherical-crown-shaped cover body. Through the cutting tool, the problem that a tip locating hole in the center point ofthe outer side face of a lathe tailstock side fixture is likely to deviate in the process of cutting the annular outer edge of the thin-wall spherical-crown-shaped cover body is solved. The cutting tool comprises a lathe spindle three-jaw fixture (1), a lathe tailstock locating cone hole (14) and the thin-wall spherical-crown-shaped cover body (4). A lathe tailstock side fixture annular pressingring (6) is arranged on the thin-wall spherical-crown-shaped cover body. A lathe tailstock side fixture center cylinder (8) is arranged in the center of the lathe tailstock side fixture annular pressing ring. Radial fixture ribs (7) are arranged between the lathe tailstock side fixture annular pressing ring and the lathe tailstock side fixture center cylinder at intervals. A radial bearing (9) isarranged in an inner cavity hole of the lathe tailstock side fixture center cylinder. The outer end of a radial bearing center shaft (10) is arranged in the lathe tailstock locating cone hole (14). The cutting tool guarantees that center axis cannot get deflected all the time in the process of cutting workpieces in batches.

Description

technical field [0001] The invention relates to a cutting tool fixture for an annular outer eave, in particular to a cutting tool for clamping and cutting the annular outer eave of a thin-walled spherical cap. Background technique [0002] A spherical cover with a ring-shaped outer eaves with a thin wall thickness is generally formed by stamping a thin metal plate to form a spherical cover, and a ring-shaped ring will be formed on the circular outer edge of the spherical cover. For the ring-shaped outer eaves, due to the irregular extension of the edge when stamping the spherical crown cover body, the outer diameter of the ring-shaped outer eaves formed after stamping is inconsistent, which does not meet the product assembly requirements. It is necessary to adjust the ring-shaped outer eaves Carry out cutting to make the outer diameter of the annular outer eaves consistent. Cutting pins are generally carried out on a lathe. During turning, the inner side of the spherical cr...
