Device and method for testing performance and durability of multi-axial pneumatic switch

The invention provides a device and a method for testing the performance and durability of a multi-axial pneumatic switch. The device comprises a PLC control system, a pneumatic system, an executing mechanism, a load system and a multi-way switch. The pneumatic system comprises an air pump, an air storage tank, a powder water air filter, a hydraulic valve, an atomized lubricator, a pressure relayand N air cylinder control circuits connected with the pressure relay, wherein each air cylinder control circuit comprises a two-position five-way electromagnetic valve and an air cylinder, and the Nair cylinders are arranged in different directions. The executing mechanism comprises N thrust needles, the thrust needles are connected with the air cylinders in a one-to-one correspondence mode, andn is greater than or equal to 2. The PLC control system sends a control instruction to the pressure relay according to preset action sequence data to control each two-position five-way electromagnetic valve to be switched on.
