The present invention discloses a novel composite type torsion beam positioning detection device. The device is characterized in that the device comprises a bottom plate; the bottom plate is providedwith X-direction limiting devices, a Y-direction clamping device, Z-direction limiting and clamping devices and detection devices; each Z-direction limiting and clamping device comprises a supportingstage and a Z-direction quick clamp which is located above the supporting stage and is matched with the supporting stage; each detection device comprises a detection supporting seat and a detection pin which movably extends out from the detection supporting seat; and the detection pins are located in spaces formed by the supporting stages of the Z-direction limiting and clamping devices and the Z-direction quick clamps when the Z-direction quick clamps are in clamping states. According to the novel composite type torsion beam positioning detection device, after X-direction positioning and Y-direction positioning are performed, the Z-direction limiting and clamping devices position two ends of each of a left dragging arm and a right dragging arm of a torsion beam in a Z direction, in this condition, the torsion beam can be positioned the most firmly, so that the detection device is arranged there, and therefore, detection can be performed under a stable state; and when the detection pins can pass through bushing holes, a part is qualified.
