[0002] After the automotive gearbox is produced on the production line, it is necessary to check the oil outlet pressure and the box before going offline. Usually, before the gearbox enters the test bench, the quick-insertion oil pipe is manually connected to the gearbox pressure test port. Connect the connector to the pallet tooling of the test bench with a hose, and then there is a mechanism for connecting the oil pipe on the test bench to the quick plug on the pallet of the tooling, so as to realize the function of detecting oil pressure. This method can achieve the purpose of testing, but it needs Manually operate the quick-plug connector and the oil pipe, and the oil pipe must correspond to the quick-connect connector one by one. This process is labor-intensive, and it is completely dependent on manual judgment, which cannot effectively prevent mistakes; secondly, during the test process, for different types of gearboxes , it is necessary to change the type of the box. When changing the type, it is necessary to use the type change plate to cooperate with the hydraulic torque converter clamped by the main drive jaws to position the box. The thickness of the type change plate currently used is a fixed value, resulting in After the gearbox is clamped in place, the relative position and distance of the hydraulic torque converter clamped by the main drive jaws are inconsistent. The electric cylinder of the main drive moving mechanism needs to move different displacements when testing different boxes, and it needs to be called during the changeover process. Different programs make programming cumbersome, and it takes a long time to change the type change plate connected to the tooling plate, which is labor-intensive: In addition, during the test process, it is necessary to change the gear of the gearbox to check its shifting force and shifting force. Displacement detection, because the measurement accuracy is not high, and the parameter data obtained from the test need to be manually calculated and sorted, and the relationship curve between the parameters cannot be obtained, resulting in low test efficiency and low accuracy
