[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Specific examples are given below.

[0017] See also Figure 1 and Figure 2 A car wheel hub milling tool comprises a base plate 1, a pull rod 2, a core shaft 3 and a car wheel hub workpiece 6, a first cylinder 4 is installed inside the core shaft 3, a pull rod 2 is installed at the telescopic end of the first cylinder 4, and the pull rod 2 passes through the core shaft 3 and is installed with an expansion sleeve 9 for limiting the position of the car wheel hub workpiece 6, the car wheel hub workpiece 6 is located on the core shaft 3, and the pull rod 2 passes through the car wheel hub workpiece 6.

[0018] A thread is provided on the outer side of the top end of the pull rod 2, and a nut 10 is threadedly installed on the top end of the pull rod 2 to achieve blocking and limiting of the expansion sleeve 9.

[0019] A positioning pin 5 for positioning the automobile hub workpiece 6 is arranged on the mandrel 3. When the automobile hub workpiece 6 rotates, the positioning surface of the blank fits with the positioning pin 5 to complete the positioning.

[0020] A conical protrusion is arranged at the top of the mandrel 3 , and the expansion sleeve 9 is located outside the conical protrusion. When the expansion sleeve 9 is raised or lowered, it cooperates with the conical protrusion of the mandrel 3 to fix and release the automobile hub workpiece 6 .
