Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3The utility model provides a technical solution: a stabilizer bar fatigue test workbench, including a test bench 1, on which a stabilizer bar clamping device and a fatigue test device are installed, the stabilizer bar clamping device includes a screw lift seat 2, on which a bracket 6 for placing a stabilizer bar body 10 is fixed, a liftable pressing plate 4 is installed on the screw lift seat 2 just above the bracket 6, and the lifting and lowering of the pressing plate 4 is driven by the screw lift seat 2, and the fatigue test device includes a cam disc 8, on which an anti-slip slide seat 12 is slidably installed, the anti-slip slide seat 12 and both ends of the stabilizer bar body 10 are rotatably connected by a pull rod 9, and the stabilizer bar body 10 is continuously pulled by the pull rod 9 to perform a fatigue test of the stabilizer bar body 10.

[0021] like Figure 2 As shown, the bracket 6 is in a "V" shape, and the stabilizing rod body 10 is placed in the middle of the "V", with its two sides respectively abutting against the side walls of the bracket 6, and is not easy to shake or shift. The bracket 6 and the screw lifting seat 2 are fixedly connected by a bracket 5.

[0022] like Figure 2 As shown, a guide ring 3 is sleeved on the screw lifting seat 2, and the guide ring 3 and the pressure plate 4 are fixedly connected by a bracket 13. The bottom sides of the pressure plate 4 away from the bracket 13 are respectively extended downward and fixed with anti-slip parts 41. The design of the anti-slip part 41 improves the stability of the stabilizer bar body 10 when it is squeezed and fixed.

[0023] A screw (not shown in the figure) is rotatably installed inside the screw lift seat 2, and an internal threaded slider (not shown in the figure) is sleeved on the screw. One end of the internal threaded slider extends to the outside of the screw lift seat 2 and is fixedly connected to the guide sleeve 3. Specifically, when in use, the motor on the screw lift seat 2 is started to drive the screw to rotate, thereby driving the pressure plate 4 to move up and down along the guide of the screw lift seat 2.
