The invention relates to the technical field of detection devices, in particular to an automobile four-wheel positioning detection device. The device comprises a rotating circular truncated cone, a supporting assembly, a first detection assembly, a second detection assembly and a driving assembly, a circular ring body matched with the rotating circular truncated cone is arranged on the outer side wall, close to the top of the rotating circular truncated cone, a strip-shaped groove is formed in the middle of the rotating circular truncated cone, and stroke grooves are symmetrically formed in the two ends, in the short edge direction of a notch of the strip-shaped groove, of the top of the rotating circular truncated cone, limiting grooves are symmetrically formed in the two ends, in the long edge direction of a notch of the strip-shaped groove, of the top of the rotating circular truncated cone, the supporting assembly comprises a supporting base, a first electric hydraulic column, a second electric hydraulic column, a trapezoidal slope and a driven sliding block, the first detection assembly is arranged in the strip-shaped groove, and the second detection assembly is arranged on the circular ring body, the driving assembly comprises a driving motor, a screw rod and an electric control steering seat; the problems that in the prior art, the application range is narrow, the capacity of detecting the performance of a shock absorber at a single wheel does not exist, and the detection effect is poor can be effectively solved.
