Abstract

The invention provides a calibration device for a force loading mechanism of an elastic part, which relates to the technical field of calibration devices. The force loading mechanism of an elastic part includes: a transmission frame; a movable block is arranged on the transmission frame; The shaft seat body on the support seat, the support seat is fixed on the movable block, the shaft seat body is provided with a rotation through hole, and the shaft body passes through the rotation through hole; the flipping part includes a fixedly connected active plate and a driven plate, the active plate The plate is connected to the shaft body; the two ends of the force sensor are respectively connected to the active plate and the force loading rod. The calibration device includes a code disc and a weight. The code disc includes a disc body and a plug-in block fixed at the bottom of the disc body. There is a longitudinal limit hole, when the force loading mechanism of the elastic part is in the calibration position, the end of the force loading rod is inserted into the longitudinal limit hole, the end of the force loading rod contacts the bottom surface of the code disc, and the weight Place it on the code wheel. The invention has the advantages of simple structure, reliable use and reduced labor intensity.

Description

technical field [0001] The invention relates to the technical field of calibrating devices, in particular to a calibrating device for a force loading mechanism of an elastic part. Background technique [0002] As one of the main power sources and energy transfer units, the electro-hydraulic system is widely used in the field of industrial control. In this system, the electrohydraulic servo valve is the main control unit. The performance of the torque motor composed of electromagnetic components, elastic parts and fluid determines the control accuracy of this type of servo valve. The elastic parts in the torque motor are used as force-sensitive devices to obtain feedback control signals. The stiffness characteristics of the elastic parts have an important impact on the performance of the electro-hydraulic servo valve, which determines the control accuracy, sensitivity and other performance indicators of the electro-hydraulic servo valve. [0003] In the design process of t...
