[0044] First oil - inlet joint 23, one end of the first oil circuit 22 far from the first oil - outlet holes 21 penetrates through the side of the oil - passing plate 2 and is butted with the first oil - inlet joint 23;

[0045] Assembly hole 24, opened on the top of the oil - passing plate 2, for fixing the oil - pressure fixture to be tested.

[0046] The testing method of the prior art is as follows: install an oil - inlet joint on each oil - inlet hole of the first oil - pressure fixture (not shown in the figure), and connect it to the input end of a hydraulic station (not shown in the figure) through a pipeline. When testing the second oil - pressure fixture, it is necessary to remove the aforementioned oil - inlet joint from the first oil - pressure fixture and install it into the oil - inlet hole of the second oil - pressure fixture. When the batch of fixtures to be tested is large, the testing efficiency is low.

[0047] The testing method of this embodiment is as follows: observe the number and position of the oil - inlet holes on the oil - pressure fixtures in the same batch, and divide the oil - pressure fixtures with the same number and position of oil - inlet holes into a sequential testing order to reduce the frequency of replacing the first oil - inlet joint 23. Specifically, first observe the number and position of the oil - inlet holes of the oil - pressure fixture to be tested, then place the oil - pressure fixture on the oil - passing plate 2 and fix it through the assembly hole 24. According to the number and position of the oil - inlet holes of the oil - pressure fixture known above, deduce the number and position of the first oil - outlet holes 21 that need to output oil. Finally, select the first oil - inlet joint 23 that needs to be butted with the output end of the external hydraulic station according to the number and position of the aforementioned first oil - outlet holes 21, and butt the oil - outlet end of the oil - pressure fixture with the input end of the hydraulic station. After forming an oil circuit, the testing work of the oil - pressure fixture can be carried out; further, the assembly hole 24 is a threaded hole, and the oil - pressure fixture is detachably fixed to the oil - passing plate 2 through screws.
