[0011] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0012] See Figure 2 , Figure 3 A center hole rotary clamping oil cylinder for automobile steering knuckle processing comprises a cylinder body 1, on which three rotary clamping oil cylinders 2 are arranged, and piston rods 3 of the rotary clamping oil cylinders are respectively connected to fixed pressure plates 4, on which pressure heads 5 are respectively arranged, and the three rotary clamping oil cylinders are composed of three rotary cylinders, which share one cylinder body with a compact structure, and can effectively ensure uniform pressure during the clamping of the automobile steering knuckle, and ensure the clamping and positioning effect of the automobile steering knuckle, thereby effectively ensuring the subsequent processing quality of the automobile steering knuckle.

[0013] The pressure head 5 includes a clamping head 6, and a through hole 7 is respectively arranged on the fixed pressure plate 4. The bolt 8 passes through the through hole 7 to connect the clamping head 6, so that the pressure head can be replaced. Different clamping heads can be replaced according to different clamping requirements, thereby improving the adaptability of the center hole rotary clamping cylinder for automobile steering knuckle processing. At the same time, when the clamping head is damaged, the clamping head can be replaced separately without replacing the entire pressure head, thereby effectively reducing the production cost.

[0014] A piston rod cavity 9 is arranged on the cylinder body 1, and a rotary pressing cylinder piston rod 3 is arranged in the piston rod cavity 9. A spiral groove 10 is arranged on the rotary pressing cylinder piston rod 3. A ball head 11 is arranged in the piston rod cavity 9 corresponding to the spiral groove 10. The ball head 11 is connected to the cylinder body 1. During the movement of the rotary pressing cylinder piston rod, the rotation of the rotary pressing cylinder piston rod is realized due to the cooperation between the ball head and the spiral groove, thereby driving the fixed pressing plate and the pressure head to rotate, further ensuring uniform pressure during pressing, ensuring the pressing and positioning effect of the automobile steering knuckle, thereby effectively ensuring the subsequent processing quality of the automobile steering knuckle.

[0015] A liquid inlet 12 and a liquid outlet 13 are provided on the cylinder body 1 corresponding to the piston rod chamber 9. The liquid inlet 12 and the liquid outlet 13 are connected to the piston rod chamber 9 to realize the inflow and outflow of oil into and out of the piston rod chamber.
