Microcomputer-controlled pipe ring stiffness testing machine

The utility model belongs to the technical field of pipe rings, and particularly relates to a microcomputer-controlled pipe ring stiffness testing machine which comprises fixing frames, the fixing frames are fixedly installed at four corners above the ground, supporting plates are fixedly installed between one sides of the fixing frames and are arranged in a bilateral symmetry mode, and a sliding frame is installed on one side of each supporting plate in a sliding mode. Through the arranged sliding assembly, in the pipeline detection process of the device, a worker does not need to lift a pipeline, a clamping plate can slide, the worker does not need to carry out feeding and discharging before and after the pipeline is detected, time and labor are saved for the worker, and the labor intensity of the worker is low; according to the pipeline clamping device, through the arranged clamping assembly, the periphery of a pipeline can be fixed in the pipeline clamping process, and the clamping device is of an arc sur
