Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
As shown in Figure 3, motor stator core buckle piece press fitting clamping fixture, comprises chassis 1, expansion set 3, stripper plate 6 and upper pressed tyre 4.
As shown in accompanying drawing 3 and accompanying drawing 4, expansion set 3 is closed up by three limb 3-1 and is formed cylindrical, and the upper and lower two ends of limb are respectively equipped with inner conical surface 3-2.
As shown in Figure 3, chassis 1 is provided with circular groove 1-1, with the inclined plane 1-2 coordinated with limb bottom inner conical surface on the groove 1-1 inner circle cell wall of chassis, as shown in Figure 5, during work, the bottom of expansion set 3 is positioned at circular groove 1-1.
