Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] The ultra-large knife-edge type torque standard machine arm beam micro-lifting device of the present invention can realize the lifting amount of the arm beam by 0.03 mm to 0.08 mm.

[0018] The concrete implementation method of the present invention is as follows:

[0019] The schematic diagram of the overall structure of the device is shown in figure 1 As shown, a super-large knife-edge torque standard machine force arm beam micro-jacking device, including force arm beam 1, force arm beam support 2, base 3, knife holder 4, tool 5, force sensor 6, high precision Drive motor 7, jacking column 8, high-precision non-contact displacement sensor 9. The force arm crossbeam 1 can be lifted slightly by 0.03mm~0.08mm through the micro-displacement jacking of the four jacking columns jointly controlled by the pressure sensor and the laser displ...

Abstract

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.

Description

technical field [0001] The invention relates to a measurement detection, torque detection calibration, and torque testing device, in particular to a micro-lifting device for a force arm crossbeam of a super-large knife-edge torque standard machine. Background technique [0002] The ultra-large knife-edge torque standard machine is a high-precision ultra-large-range torque measurement equipment. Its structure is mainly composed of a weight group, a force arm beam, a force arm support component, a force arm balance mechanism, and a base. The arm support mechanism is the core component of this equipment, and a high-precision knife-edge support mechanism can usually be used. The knife-edge support mechanism is mainly composed of a high-strength knife and a knife holder. During use, the tool is erected on the tool holder and can swing freely with a single degree of freedom to form a fulcrum structure. The beam of the force arm of the ultra-large knife-edge torque standard machi...
