[0026] In the embodiments of the present application, the tool chatter phenomenon generally refers to unwanted vibration occurring between a tool and a workpiece during machining, which can cause fluctuations in the machined surface and affect machining precision and surface quality. For example, for a ring with specifications of φ316xφ310x28mm, when a boss as shown in the following figure is required to be machined on the inner and outer walls, and the height of the boss is 0.6mm, and the perpendicularity and run-out requirements are only 0.02, it is difficult to ensure the technical requirements of perpendicularity and run-out of the machined part during machining due to the tool chatter phenomenon.
[0027] Embodiment 1: The present embodiment describes a machining tool for machining the inner diameter boss of a thin-walled ring and the outer diameter boss of a thin-walled ring, as shown in Figure 1 , the machining tool comprises:
[0028] a cylindrical base 1, a plurality of pressing plates 2 for fixing the thin-walled ring are arranged on the base 1, the pressing plates 2 are fixed on the base 1 by screws 3, and the outer side of the pressing plate 2 is clamped with the inner side of the thin-walled ring.
[0029] Specifically, as shown in Figure 2 , the outer side of the pressing plate 2 is provided with a clamping block 6, and the inner side of the thin-walled ring is provided with a groove, and the clamping block is clamped with the groove.
[0030] When machining the inner diameter boss of the thin-walled ring, an annular sleeve 4 is sleeved on the outer side of the thin-walled ring. The inner diameter of the sleeve 4 is 0.04mm larger than the outer diameter of the thin-walled ring.
[0031] When machining the outer diameter boss of the thin-walled ring, an annular inner support 5 is sleeved on the inner side of the thin-walled ring, and the top of the inner support 5 is provided with an upper cover 7. The outer diameter of the inner support 5 is 0.03mm smaller than the inner diameter of the thin-walled ring.
[0032] The working process of the machining tool provided in the present embodiment will be described below.
[0033] According to the technical requirements, the material is cut, and then machined into a thin-walled ring with steps on the inner and outer diameters. A groove as shown in Figure 3 is machined inside the thin-walled ring with a larger wall thickness, so that the pressing plate 2 can fix the thin-walled ring on the base 1, and ensure the stability of the thin-walled ring during later machining.
[0034] Place the thin-walled ring on the base 1, ensure that the thin-walled ring is concentric with the base 1, and then fix the thin-walled ring on the base 1 by the pressing plate 2 and the screw 3.
[0035] When machining the inner diameter boss of the thin-walled ring, the sleeve 4 is sleeved on the outer side of the thin-walled ring (as shown in Figure 4 ), the outer diameter of the thin-walled ring is 0.04mm different from the inner diameter of the sleeve, and the sleeve is removed after machining;
[0036] When machining the outer diameter boss of the thin-walled ring, the inner support 5 is sleeved on the inner side of the thin-walled ring (as shown in Figure 5 Fig. 2), and then machining is performed. After machining is completed, the inner support 5 is taken out by the upper cover 6. The outer diameter of the inner support 5 is about 0.03 mm different from the inner diameter of the thin-walled ring. Due to the small size difference, the thin-walled ring is not easy to deform during machining, and the dimensional accuracy requirement can be ensured.
[0037] Specifically, in order to facilitate the taking out of the inner support 5, two steps with an outer diameter smaller than the outer diameter of the upper cover 6 are arranged at the connection between the above-mentioned upper cover 6 and the inner support 5.
[0038] Example 2: The difference between this example and Example 1 is that the inner diameter of the outer sleeve 4 is 0.05 mm larger than the outer diameter of the thin-walled ring. The outer diameter of the inner support 5 is 0.05 mm smaller than the inner diameter of the thin-walled ring.
[0039] Example 3: The difference between this example and Example 1 is that the inner diameter of the outer sleeve 4 is 0.03 mm larger than the outer diameter of the thin-walled ring. The outer diameter of the inner support 5 is 0.04 mm smaller than the inner diameter of the thin-walled ring.
