Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0031] Example

[0032] The following is combined with Figure 1-3 An auxiliary positioning tool for cutting railway wheels with a plasma cutting machine in an embodiment is described. Figure 1 and 2 As shown, it includes a support block 1 and multiple support plates 2, and the railway wheel cake is placed on the support block 1 and multiple support plates 2 for support. The support plates 2 are evenly arranged along the circumference of the support block 1, and the length direction of the support plates 2 passes through the center of the support block 1; the wheel cake is evenly divided into multiple parts along the support plate 2, and a movable clamping block 3 is also provided on the support plate 2 for clamping the railway wheel cake. The movable clamping block 3 is provided with a score line 31. After the movable clamping block 3 is moved to clamp the railway wheel cake, the score line 31 is aligned with the edge of the wheel cake. When cutting, the score line 31 is aligned, and the railway wheel cake can be cut into equal parts along the support plate 2. The operation is simple, and no marking and measuring operations are required, which saves time and effort. The support block 1 and the support plate 2 are used as supports, and the railway wheel cake is clamped by the movable clamping block 3. After cutting a wheel cake petal, it will not affect the uncut part and cause it to be misaligned, which is beneficial to subsequent cutting.
