Abstract
The present application provides an adjustable mandrel and a fixture. The adjustable mandrel comprises an outer-diameter adjusting assembly and a height adjusting assembly, wherein the external diameter and the height of the mandrel can be adjusted according to wheels in different specifications, the wheels in different specifications are clamped, and the radial positioning of the wheel and the axial positioning of the wheel during second-step processing are realized. Two adjusting systems supplement each other, so that the structure is novel, the concept is ingenious, the universality is high, the application range is wide, and the machining cost is reduced.
Claims18
An adjustable mandrel, comprising an outer-diameter adjusting assembly and a height adjusting assembly, wherein the outer-diameter adjusting assembly can adjust the diameter of a circumcircle on an upper end face of the mandrel to make an upper end of the mandrel be matched with the diameter of a central hole of a wheel, and the height adjusting assembly can adjust the height of the mandrel so that the upper end of the mandrel extends into the central hole to achieve radial positioning of the wheel.
A fixture, comprising pressing jaws and a mandrel seat, the pressing jaws being evenly distributed along the circumference, and the mandrel seat being fixed at a central position of the fixture, wherein the fixture further comprises a adjustable mandrel, and the adjustable mandrel is mounted to the mandrel seat;
- the adjustable mandrel, comprising an outer-diameter adjusting assembly and a height adjusting assembly, wherein the outer-diameter adjusting assembly can adjust the diameter of a circumcircle on an upper end face of the mandrel to make an upper end of the mandrel be matched with the diameter of a central hole of a wheel, and the height adjusting assembly can adjust the height of the mandrel so that the upper end of the mandrel extends into the central hole to achieve radial positioning of the wheel.
