Zusammenfassung:The invention relates to a force arm cross beam micro jacking device of an ultra-large tool edge type torque standard machine. The force arm cross beam micro jacking device is provided with a force arm cross beam, the middle of the force arm cross beam is vertically erected on a tool bearing seat through a tool, the force arm cross beam can swing freely around a supporting point formed by a tool component and the tool bearing seat, four force arm cross beam supports are arranged and symmetrically distributed on the two sides of the force arm cross beam in a bilateral symmetry mode, jacking stand columns are arranged below the force arm cross beam supports respectively, the lower portion of each jacking stand column is connected with a corresponding jacking assembly formed by a force sensor and a high-precision driving motor, and the jacking assemblies are fixedly connected with the base. Non-contact high-precision displacement sensors fixed to the base are arranged below the two sides of the force arm cross beam respectively. The self-locating function is achieved, the position of the force arm cross beam can be effectively limited, and it can be guaranteed that the relative position between the tool and a tool bearing can be completely restored to the initial assembling position of the force arm cross beam in the lifting process. Therefore, the common problems that in the tool edge type torque standard machine, the position of the force arm cross beam is uncertain, and the force arm cross beam can be deviated easily are solved.
