A spinning wheel 6 is rotatably installed on the opposite side of the fixed spinning seat 2 and the dynamic spinning seat 3, and the rotation drive unit 5 is used to drive the spinning wheel 6 to rotate. A supporting table 7 for supporting and placing the steering machine rack piston rod is installed between the fixed spinning seat 2 and the dynamic spinning seat 3, and the supporting table 7 is slidably installed on the spinning table 1 in the horizontal direction.

[0033] During the spinning process, the worker places the steering rack piston rod support on the support platform 7, and then starts the feed drive unit 4 and the rotation drive unit 5, so that the spinning wheels 6 on the fixed spinning seat 2 and the dynamic spinning seat 3 can clamp and spin the steering rack piston rod for spinning. At the same time, when the feed drive unit 4 drives the dynamic spinning seat 3 to move, the spinning wheel 6 on the dynamic spinning seat 3 continuously pushes the steering rack piston rod. At this time, the steering rack piston rod can be synchronously pushed and moved along the horizontal direction with the support platform 7, so that the steering rack piston rod can remain relatively stable during the spinning process, so as to improve the stability of its spinning process.

[0035] During the spinning process, the piston rod of the feed cylinder 41 is pushed outward, causing the movable spinning seat 3 to move in the opposite direction and move toward the fixed spinning seat 2; similarly, when the spinning work is completed, the piston rod of the feed cylinder 41 is retracted, causing the movable spinning seat 3 to move in the opposite direction and move away from the fixed spinning seat 2.

[0036] In this embodiment, a tension seat 43 is fixed to the spinning table 1 on one side close to the fixed spinning seat 2. The tension seat 43 is located on the left side of the fixed spinning seat 2, and the tension seat 43 is arranged opposite to the reverse thrust seat 42.

At the same time, since both ends of the tension rod 44 are fixedly connected to the tension connection hole through the locking nut 46, a detachable connection is formed between the tension rod 44 and the tension seat 43 and the reverse thrust seat 42, which facilitates the workers to disassemble and install the tension rod 44.

[0039] Specifically, in this embodiment, the supporting platform 7 includes a supporting rod 71 and a plurality of supporting seats 72 fixedly installed on the supporting rod 71 along the length direction of the supporting rod 71; wherein, a horizontal slide rail 73 is fixed on the spinning platform 1, a horizontal slider 74 is slidably arranged on the horizontal slide rail 73, and the supporting rod 71 is fixedly installed on the horizontal slider 74, so that the supporting platform 7 can be slidably installed on the spinning platform 1 along the horizontal direction.

[0040] Specifically, the support seat 72 includes a support base 721 and a plurality of pairs of support bearings 722 rotatably mounted on the top of the support base 721, and the plurality of pairs of support bearings 722 are used to support the steering rack piston rod.

[0041] During actual use, workers can move and adjust the supporting seat 72 along the length direction of the supporting rod 71 to fix the supporting seat 72 at the corresponding supporting connection hole 75 so as to support the steering rack piston rods of different lengths.
