[0048] The rotation positioning fixture 4 is installed on the surface of the workbench 1, and the rotation positioning fixture 4 includes a front positioning seat 41, a rear positioning seat 42 and a rotating assembly 43;

[0049] The front positioning seat 41 and the rear positioning seat 42 are both provided with a receiving groove for receiving the end of the piston rod. The rotating assembly 43 is installed in the receiving groove to drive the rotation of the piston rod in the receiving groove.

[0050] During use, the piston rods are placed one by one into the corresponding receiving grooves, and the surface of the piston rods is roll-formed with the cooperation of the moving mechanism 2 and the rolling mechanism 3 to form a cold-worked hardened layer on the surface of the piston rod. The piston rod in the receiving groove is then rotated by the rotating component 43, and the other side of the piston rod is turned upward, and roll-formed again, thereby realizing automatic rolling of various surfaces of the piston rod. This application has a high degree of automation and is suitable for large-scale promotion and use.

[0051] In this embodiment, the rotating assembly 43 includes a driving roller 431, a driven roller 432, a synchronous belt 433 and a first motor 434;

[0052] The active roller 431 and the driven roller 432 are installed in the receiving groove in a symmetrical manner.

[0054] The first motor 434 is connected to one end of the active roller 431 or the driven roller 432;

[0055] During use, it should be noted that the active roller 431 is driven to rotate by the first motor 434 , and the driven roller 432 rotates synchronously under the action of the synchronous belt 433 , thereby rotating the piston rod supported between the active roller 431 and the driven roller 432 .

[0056] It should be noted that the active roller 431 and the driven roller 432 in each rotating assembly 43 can be connected via the same synchronous belt 433 , thereby achieving synchronous rotation of each rotating assembly 43 controlled by a first motor 434 .

[0057] In this embodiment, the rotary positioning fixture 4 further includes a slide rail, and the rear positioning seat 42 is slidably mounted on the slide rail and fixed by a bolt fixing member;

[0061] The second motor 24 is connected to one end of the screw rod 22;

[0062] The moving block 23 is threadedly connected to the screw rod 22;

[0063] During use, the second motor 24 drives the screw rod 22 to rotate, thereby driving the moving block 23 to move along the length direction of the screw rod 22 .

[0064] In this embodiment, the rolling mechanism 3 includes a first press frame 31, a second press frame 32, a rolling wheel 33, a guide rod 34 and a pneumatic cylinder 35;

[0069] The pneumatic cylinder 35 is mounted on the top of the first mold frame 31, and the piston rod of the pneumatic cylinder 35 is connected to the second mold frame 32;

[0070] During use, the second knurling frame 32 is driven to rise and fall in the first knurling frame 31 by the pneumatic cylinder 35 , and then cooperates with the rolling wheel 33 to roll the surface of the piston rod.

[0071] The working principle of this utility model is as follows:

[0072] The piston rods are placed one by one into the corresponding receiving grooves, and the surface of the piston rods is roll-formed with the cooperation of the moving mechanism 2 and the rolling mechanism 3 to form a cold-worked hardened layer on the surface of the piston rod.
