As shown in fig. 1 to 2, an embodiment of the present application provides a lathe fixture for machining an adapter workpiece, including a mounting base 10 to which a lathe is attached and a fixture body 20 located on top of the mounting base.

In this embodiment, the mounting base 10 is cylindrical for attachment to a lathe.

Further, the connecting surface of the clamp body 20 and the mounting base 10 is circular, and the diameter of the connecting surface is larger than that of the mounting base 10. Preferably a circular face, which is more stable to both attachment and support.

Further, the mounting base 10 may be provided with a connecting hole connected with the lathe, and the connecting hole may be a threaded hole, and the mounting base 10 is in threaded connection with the lathe.

Further, the bottom of the mounting base 10 can be further provided with a hollowed-out area, and the hollowed-out area can reduce the material of the fixture mounting base 10, so that the manufacturing cost of the mounting base 10 is reduced.

In this embodiment, the fixture body 20 is located on top of the mounting base 10 and is integrally formed therewith, and the fixture body 20 is used for supporting and positioning a workpiece. The supporting surface of the clamp body 20 is a stepped inclined surface, the inclined surface comprises a first horizontal surface 21, a second inclined surface 22 and a third horizontal surface which are sequentially connected into a whole, the first horizontal surface 21 and the second horizontal surface 23 are parallel to the mounting base 10 and are arranged in a high-low mode, and a plurality of positioning holes 221 are uniformly formed in the second inclined surface 22 along the edge, and the shape of the second inclined surface is matched with the shape of the connecting base 31 of the workpiece 30.

As shown in fig. 1 and 2, the area of the second inclined surface is significantly larger than the first horizontal surface 21 and the second horizontal surface 23, and the length of the second inclined surface 22 at the junction side of the first horizontal surface 21 is smaller than the length of the second inclined surface at the junction side of the second inclined surface and the second horizontal surface 23.
