Description
Technical Field
The utility model relates to the field of mechanical measurement, in particular to a calibration device for a comparison type multi-component force sensor.
Background
Along with the continuous promotion of productivity level, multicomponent force sensor obtains more and more extensive application in fields such as artificial intelligence, robot, aerospace, automotive industry, heavy machinery, intelligent manufacturing, advanced medical treatment, and the quantity value problem of tracing to multicomponent force sensor also emerges thereupon: when the traditional force standard machine is used for calibration, a special clamp needs to be customized to limit the displacement of a calibrated sensor in a test component direction, and the problems of repeated installation, limited positioning precision, incapability of testing coupling errors, complex operation process and the like exist. Therefore, it is necessary to design a dedicated calibration device for the technical features of the multi-component force sensor.
The calibration device for the multi-component force sensor which is mainstream at home and abroad can be classified according to comparison standards and comprises the following components: 1. a calibration device which takes the weight gravity as a comparison standard; 2. a calibration device which takes the single component standard dynamometer as a comparison standard; 3. and the calibration device takes the multi-component force sensor as a comparison standard. The calibration device using the weight gravity as a comparison standard usually uses a steel cable as a connecting piece between a loading head and a force source. For guaranteeing the measuring accuracy, receive the restriction of weight volume simultaneously, calibrating device is great to the requirement of installation space, so its measurement upper limit generally does not exceed 400kN, can't satisfy the calibration demand of big power value sensor, and this type of device can only carry out hierarchical loading. The single component standard dynamometer is used as a calibration device for comparison and comparison standards, the selection range of the force source is relatively wider, the test range can be greatly improved, meanwhile, a smaller installation space is ensured, and the operation is more convenient. However, since the force value is generally transmitted from the force source system to the calibrated sensor through the rigid structural member, a large error is generated due to additional frictional resistance when the coupling error is tested. The calibration device takes the multi-component force sensor as a comparison standard and carries out calibration by directly comparing the output of the sensor to be calibrated and the output of the multi-component force sensor of the device. However, since the geometric centers of the two sensors cannot coincide in at least two orthogonal directions, the direct measurement results inherently have systematic errors due to geometric configuration. And the multi-component force sensor also has the defect of difficult traceability, and can generate adverse effect on the subsequent maintenance work of the device.
In summary, in view of the above, how to reduce the space volume occupied by the calibration apparatus for multi-component force sensor and improve the flexibility of the apparatus for subsequent tracing as much as possible on the premise of improving the test range and reducing the crosstalk error is a technical problem to be solved urgently by the calibration apparatus.
