Referring to fig. 3, the section of the spline-like guide block 3 is arc-shaped, and comprises a segment of circular arc (corresponding to the target circular arc surface 31) and a segment of chord (corresponding to the surface attached to the flat supporting surface 12), and the spline-like guide block 3 is manufactured by a rectangular plate 2.
Accordingly, the present disclosure provides a supporting shaft 1 for supporting a plate 2, which includes a flat supporting surface 12 parallel to a central axis of the supporting shaft 1, the plate 2 can be supported on the flat supporting surface 12 in a fitting manner (see fig. 1 and fig. 2), the supporting shaft 1 is clamped on a fixture of a lathe, the supporting shaft 1 is driven by the lathe to rotate around a central axis thereof, the lathe can lathe a target arc surface 31 on the plate 2 (the surface of the plate 2, which is bonded on the flat supporting surface 12, intersects with the target arc surface 31) to form a spline-like guide block 3 with an arc-shaped cross section, and finally the spline-like guide block 3 is removed from the supporting shaft 1 (the supporting shaft 1 can be removed from the fixture first).
In the scheme, the spline-like guide block 3 is manufactured by turning the plate 2, so that the material needing turning is reduced, the processing cost and the material cost are reduced, the process is simplified, and the processing time is shortened.
In addition, a plurality of reference arc surfaces 11 which are circumferentially spaced, coaxial and equal in diameter are arranged on the outer peripheral surface of the supporting shaft 1, the flat supporting surface 12 is located between the reference arc surfaces 11, and the target arc surface 31 and the reference arc surfaces 11 are coaxial and equal in diameter. Referring to fig. 1, a reference arc surface 11 is arranged on the outer peripheral surface of the support shaft 1, the flat support surfaces 12 are located between the reference arc surfaces 11, and the central axis of the reference arc surface 11 is the central axis of the support shaft 1, so that the turning radius of the lathe is set to the radius of the reference arc surface 11, so that a target arc surface 31 coaxial with the reference arc surface 11 and having the same diameter can be processed on the plate 2, the target arc surface 31 intersects with the plane of the plate 2 attached to the flat support surface 12 to form an arched cross-sectional shape, that is, the spline-like guide block 3 is manufactured, and the target arc surface 31 of the spline-like guide block 3 can be spliced with the reference arc surface 11 to form a complete circumferential surface.
Further, the radian of the reference circular arc surface 11 is the same, and the widths of the flat supporting surfaces 12 are the same. The radian of the reference arc surface 11 is the same, correspondingly, the circumferential distance between the flat supporting surfaces 12 is the same, the widths of the flat supporting surfaces 12 are the same, the cross-sectional dimensions and shapes of the spline-like guide blocks 3 made of the plate material 2 supported on each flat supporting surface 12 are the same, and of course, in other embodiments, the widths of the flat supporting surfaces 12 can be different to make different spline-like guide blocks 3.
