DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-3 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0028] The embodiment of the present application discloses a wheel hub inner hole processing lathe.

[0029] Reference Figure 1-Figure 3 A wheel hub inner hole processing lathe of this embodiment includes a lathe body 1 and a rotating seat 11. The rotating seat 11 is rotatably connected to the lathe body 1 in the vertical direction. The rotating seat 11 is roughly a cube and also includes a tool clamping structure 2. The tool clamping structure 2 is used to clamp the tool. The tool clamping structure 2 includes a placement block 21, a clamping block 22 and a driving member 23. The placement block 21 is fixedly connected to the side of the rotating seat 11, and the clamping block 22 is located directly above the placement block 21 and is slidably connected to the rotating seat 11 in the vertical direction. The placement block 21 and the clamping block 22 can extend into the inner hole of the wheel hub, and the driving member 23 is used to drive the clamping block 22 to slide.

[0030] Reference Figure 1-Figure 3 , place the tool on the placement block 21, and drive the clamping block 22 to slide toward the side of the placement block 21 through the driving member 23, so that the side of the placement block 21 opposite to the clamping block 22 clamps the tool; by arranging the placement block 21 and the clamping block 22 on the rotary seat 11 to clamp the tool, the placement block 21 and the clamping block 22 can be extended into the inner hole of the wheel hub to process the inner hole of the wheel hub, reducing the possibility of the tool holder colliding with the workpiece when the turning depth is large, and there is no need to extend the turning tool a large amount, reducing the possibility of the tool rod vibrating to make the surface of the turned workpiece rough, and facilitating the processing of the inner hole of the wheel hub.

[0031] Reference Figure 1-Figure 3 The placing block 21 and the clamping block 22 are respectively semi-cylindrical, and one side of the upper plane of the placing block 21 is arranged opposite to one side of the upper plane of the clamping block 22. The possibility of the placing block 21 and the clamping block 22 colliding with the side wall of the inner hole of the wheel hub is reduced.
