[0018] Embodiment one

[0019] As shown in Figure 1 and Figure 2 The automobile hub machining fixing device comprises a supporting leg 100 and a cross table plate 101,

[0020] Two ends of the horizontal table plate 101 are symmetrically provided with a first hydraulic cylinder seat 102 and a second hydraulic cylinder seat 103,

[0021] The first hydraulic cylinder seat 102 and the second hydraulic cylinder seat 103 are respectively provided with a first hydraulic cylinder 104 and a second hydraulic cylinder 105,

[0022] The first hydraulic cylinder 104 and the second hydraulic cylinder 105 are respectively provided with a first arc slot clamping part 106 and a second arc slot clamping part 107,

[0023] The horizontal table plate 101 is provided with a hub loading platform 108 between the first hydraulic cylinder seat 102 and the second hydraulic cylinder seat 103.

[0024] The working principle is that the automobile hub is horizontally arranged on the hub loading platform 108, and the first hydraulic cylinder 104 and the second hydraulic cylinder 105 are started, at this time, the first arc slot clamping part 106 and the second arc slot clamping part 107 on the first hydraulic cylinder 104 and the second hydraulic cylinder 105 are respectively in abutment and clamping with the automobile hub on the hub loading platform 108; after the corresponding mechanical processing or surface treatment is completed, the first hydraulic cylinder 104 and the second hydraulic cylinder 105 are reset, at this time, the first arc slot clamping part 106 and the second arc slot clamping part 107 are loosened from the automobile hub, and the automobile hub is unloaded.

[0025] Example two

[0026] On the basis of example one, the automobile hub machining fixing device further comprises a motor mounting plate 109 arranged on the supporting leg 100, a power motor 110 arranged on the motor mounting plate 109, a shaft coupling 111 arranged on the power motor 110, a circular groove 1081 (solid lubricating oil is added) arranged in one side of the hub loading platform 108, a second boss groove 113 arranged in the other side of the hub loading platform 108 and used in cooperation with the circular groove 1081, a first boss groove 112 arranged in the horizontal table plate 101, a bearing 116 arranged in the first boss groove 112, a rotatable table plate 114 arranged in the circular groove 1081, and a rotating shaft 115 arranged on one side of the rotatable table plate 114 and connected with the shaft coupling 111 in sequence after penetrating through the second boss groove 113, the first boss groove 112 and the bearing 116.
