Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] As shown in Fig. 1 and Fig. 2, the present invention includes a calibration table 1, a beam 2, two ball screws 3a, 3b for lifting and lowering the beam, a Z-direction loading mechanism 4, a Z-direction standard force sensor 5, an X-direction loading mechanism 6, X-direction standard force sensor 7, X-direction translation linear guide 8, Y-direction loading mechanism 9, Y-direction standard force sensor 10, Y-direction translation linear guide 11, positioning loading fixture 13, synchronous belt 14 and motor 15. The linear guide rail 8 for X-direction translation and the linear guide rail 11 for Y-direction translation are fixed on the calibration workbench 1 in a mutually orthogonal manner, and ensure a high parallelism between the translation direction and the worktable; the linear guide rail 8 for X-direction translation is installed There is ...

Abstract

The invention relates to a calibrator for a 3-way force sensor. Wherein, a X-way linear guideway for translating with a X-way loader and a Y-way linear guideway for translating with a Y-way loader are fixed perpendicular to each other on a calibrating worktable; the two ends of a beam are fixed on two ball screw for lifting the beam; the ball screws are installed vertically on the calibrating worktable; a Z-way loader is fixed on the beam; the standard force sensors that are respectively mounted on the X-, Y- and Z-way loader are intersected; an orientedly loading clamp clamps the 3-way force sensor to be calibrated, is placed on the calibrating worktable and located at the intersection of the three sensors; a motor drives the two ball screw for lifting the beam to move linearly and synchronously in Z direction. The weighing, 3-way force sensor is calibrated by a measurement comparison method. While detecting the force-measuring performance of the 3-way force sensor in any direction, one can observe the disturbance on the force measuring in another two directions, thereby the interference of forces in different directions can be reduced.

Description

technical field [0001] The invention relates to a device for measuring force, in particular to a calibration device for a three-way force sensor. Background technique [0002] At present, in my country's metrology system, the value transfer and traceability of force values ​​are becoming more and more perfect. The verification and calibration devices of unidirectional force sensors are relatively mature in terms of type and verification accuracy level, but they can be used for three-way force sensors. Devices for verification and calibration are rarely seen in national metrological technical institutions or provincial, city and county-level metrological technical institutions. With the increasing requirements for force value detection in the current industrial field, force sensors and dynamometers that can simultaneously detect three-way force are gradually being applied and promoted, but the national metrology verification regulations and / or calibration for their force measu...
