Volute spiral spring detection device

The invention relates to a volute spiral spring detection device which comprises an electrical control part and a mechanical part, wherein the electrical control part is used for controlling the action of the mechanical part and displaying detected real-time data; the mechanical part is used for executing instructions sent by the electrical control part to realize detection on a volute spiral spring. The volute spiral spring detection device has the advantages that a programmable logic controller (PLC) is adopted to control the control instructions of a test device and summarization of data; the PLC is high in reliability and high in antijamming capability; the design, mounting and debugging workload of the system is small, the maintenance is convenient and transformation is easy.
