[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the following embodiments are combined with the accompanying drawings to specifically illustrate the present invention.

A preferred multifunctional testing device is shown, comprising a testing bracket 2, an oil tank 1, an oil tank lifting mechanism, a pump body driving mechanism, and a pump body detection mechanism. The oil tank 1 is arranged on the testing bracket 2 to supply oil to the workpiece to be tested. The oil tank lifting mechanism is arranged on the testing bracket 2 and connected to the oil tank 1 to adjust the height of the oil tank 1. The pump body driving mechanism is arranged on the bracket and connected to the workpiece to be tested to drive the workpiece to be tested to move, thereby generating an oil suction action. The pump body detection mechanism is arranged on the testing bracket 2 and detects the flow rate, pressure and other data of the oil sucked by the workpiece to be tested, and then determines whether the workpiece is qualified based on the detection data.

[0035] A low-temperature chamber (not shown in the figure) is also provided outside the workpiece. The low-temperature chamber is fixed on the detection bracket 2 and cooperates with the detection bracket 2 to surround the workpiece, thereby adjusting the ambient temperature of the workpiece to be tested to simulate the low-temperature environment required for the workpiece experiment.

[0036] In addition, the oil tank lifting mechanism includes: an oil tank lifting motor 51, an oil tank lifting screw 53, a reducer 52 and an oil tank adjustment plate assembly. The oil tank adjustment plate assembly is sleeved on the oil tank lifting screw 53. The oil tank lifting screw 53 is arranged in the bracket along the lifting direction of the oil tank 1, and the oil tank lifting screw 53 is connected to the oil tank lifting motor 51 through the reducer 52.

[0037] The oil tank lifting motor 51 rotates and outputs the rotational motion to the reducer 52. The reducer 52 transmits the rotational motion to the oil tank lifting screw 53, causing the screw to rotate. The oil tank adjustment plate assembly is threadedly connected to the oil tank lifting screw 53. When the oil tank lifting screw 53 rotates, the oil tank adjustment plate assembly moves up and down along the oil tank lifting screw 53, thereby adjusting the height of the oil tank 1.

[0038] In the present invention, the height of the oil tank 1 is adjustable through the setting of the oil tank lifting mechanism, so that different types of test workpieces can be used. In addition, in the oil tank lifting mechanism, the reducer 52 is set through the setting of the screw rod and the reducer 52, and the reducer 52 changes the direction of movement, and the setting of the screw rod converts the rotational motion into linear motion, so that the adjustment of the oil tank 1 is achieved with a simple structure.
