Elastic deformation adjusting device for frame plate in FCT tester

The invention relates to an elastic deformation adjusting device for a middle frame plate of an FCT tester. The elastic deformation adjusting device comprises a pressing plate module, a needle carrierplate module, a strain gauge, a middle frame plate module, a dynamic control module and a driving module. The middle frame plate module is installed on an in-out driving module, strain gauges are installed on the middle frame plate module at equal intervals, and the strain gauges are connected with the stress analysis module to provide real-time deformation data for the stress analysis module. The dynamic control module uses the stress analysis module to collect middle frame plate module deformation real-time data input by the strain gauges, and controls the deformation of the middle frame plate module by adjusting upper and lower driving modules. According to the invention, the deformation quantity of the middle frame plate can be monitored in real time, the air pressure of a pressure regulating valve is dynamic
