[0018] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.

[0019] The technical solutions of the utility model will be described clearly and completely below with reference to the drawings and in combination with the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] The utility model will be described below with reference to Figures 1 to 5 and in combination with the embodiments.

[0021] An automatic clamping three-coordinate support comprises a bottom plate 1, a vertical plate 2, a first air cylinder 3, a sliding support 4, a fixed support 5, a second air cylinder 6, a first expansion sleeve 7, a first expansion core 8, a second expansion sleeve 9, and a second expansion core 10.

[0022] The vertical plate 2 is installed on the bottom plate 1, the sliding support 4 is installed on the vertical plate 2, the first air cylinder 3 is installed on the sliding support 4, the fixed support 5 is installed on the vertical plate 2, the second air cylinder 6 is installed on the fixed support 5, the first expansion sleeve 7 is installed on the sliding support 4, the first expansion core 8 is installed on the first expansion sleeve 7, the second expansion sleeve 9 is installed on the fixed support 5, and the second expansion core 10 is installed on the second expansion sleeve 9.

[0023] The automatic clamping three-coordinate fixture comprises a bottom plate 1, a vertical plate 2 vertically fixed on the bottom plate 1, a sliding support 4 slidably installed on the vertical plate 2, a fixed support 5 fixedly installed on the vertical plate 2, a first air cylinder 3 arranged on the sliding support 4, a second air cylinder 6 arranged on the fixed support 5, a first expansion sleeve assembly in transmission connection with the first air cylinder 3, comprising a coaxially arranged first expansion sleeve 7 and a first expansion core 8, and a second expansion sleeve assembly in transmission connection with the second air cylinder 6, comprising a coaxially arranged second expansion sleeve 9 and a second expansion core 10.

[0024] The outer diameter size of the first expansion sleeve 7 and the second expansion sleeve 9 is smaller than the inner diameter of the steering knuckle caliper hole in a non-working state. The first air cylinder 3 and the second air cylinder 6 are connected with a compressed air source through a pneumatic pipeline, and the piston rods of the two air cylinders are respectively in axial linkage with the first expansion core 8 and the second expansion core 10.

[0025] In actual use, according to the interval and height difference of the steering knuckle caliper holes, the position of the sliding support 4 is adjusted, so that the spatial positions of the first expansion sleeve 7 and the second expansion sleeve 9 correspond to the positions of the steering knuckle caliper holes.
