[0017] Please refer to Figure 1 - Figure 2 , the present utility model provides a technical solution: a piston rod straightening device for an automobile, including a straightening table 1, and further including a straightening groove 11 and a pressing strip 12. The straightening groove 11 is vertically opened on the upper surface of the straightening table 1. One side of the straightening groove 11 is semi-circular. The pressing strip 12 is slidably connected inside the straightening groove 11. A first electro-hydraulic push rod 13 is fixedly connected to one side of the straightening table 1. The telescopic end of the first electro-hydraulic push rod 13 is fixedly connected to the middle of one side of the pressing strip 12. The bottom end of the straightening groove 11 is movably connected to a top block 15.

[0018] In this technical solution, the straightening groove 11 vertically opened on the upper surface of the straightening table 1 can limit the piston rod. It should be noted that the width of the straightening groove 11 is matched with the diameter of the piston rod. By controlling the first electro-hydraulic push rod 13 to work through the corresponding controller, the pressing strip 12 can be pushed to move leftward. Since one side of the straightening groove 11 is semi-circular, the pressing strip 12 can straighten the piston rod bent on one side. It should be noted that during the handling and production process of the piston rod, it is mostly bent to one side under the action of external forces, and straightening repair can be carried out only when the bending amount is small. If it is bent in multiple directions and the bending amount is too large, even after straightening, it will affect the normal use of the piston rod. Therefore, this application is only suitable for straightening the piston rod bent on one side with a small bending amount.

[0019] In this embodiment, a second electro-hydraulic push rod 14 is fixedly connected to the bottom side of the straightening table 1, and the telescopic end of the second electro-hydraulic push rod 14 is fixedly connected to the bottom side of the top block 15.

[0020] In this technical solution, after the pressing strip 12 finishes straightening the piston rod in the straightening groove 11, control the first electro-hydraulic push rod 13 to work to drive the pressing strip 12 to move rightward and separate from the piston rod, and then control the second electro-hydraulic push rod 14 to work, which can push the top block 15 to move upward, so as to eject the straightened piston rod in the straightening groove 11, facilitating the staff to collect it.

[0021] In this embodiment, a receiving groove 16 is opened on the inner wall of the bottom end of the straightening groove 11 near the semi-circular side, and the size of the receiving groove 16 is matched with that of the top block 15.

[0022] In this technical solution, the top block 15 can be received through the receiving groove 16 to prevent the top block 15 from interfering with the straightening operation of the pressing strip 12 on the piston rod.

[0023] When an automobile piston rod straightening device is in use, the piston rod bent on one side is vertically inserted into the straightening groove 11 opened on the upper surface of the straightening table 1. By controlling the first electro-hydraulic push rod 13 to work through the corresponding controller, the pressing strip 12 can be pushed to move leftward. Since one side of the straightening groove 11 is semi-circular, the pressing strip 12 can straighten the piston rod bent on one side. After the pressing strip 12 finishes straightening the piston rod in the straightening groove 11, control the first electro-hydraulic push rod 13 to work to drive the pressing strip 12 to move rightward and separate from the piston rod, and then control the second electro-hydraulic push rod 14 to work, which can push the top block 15 to move upward out of the receiving groove 16, so as to eject the straightened piston rod in the straightening groove 11, facilitating the staff to collect it.
