Detailed Description
The following describes the present invention in detail with reference to fig. 1 to 2 by way of specific embodiments. The intelligent testing device for static balance of the aviation propeller comprises a testing shaft fixed on a base, propeller blades connected to the testing shaft through a wedge-shaped bearing, and an upper computer, wherein the upper computer mainly comprises an analog quantity signal input interface, a data processing module and a display module. The data processing module mainly refers to a CPU and the like, receives the electric signals obtained by the data interface through a signal amplification module (if necessary) through a pre-compiled software program, forms a data set (such as an axis diagram or a statistical table) by receiving the electric signals sent by the sensor, and displays the data set through a display module (mainly refers to a display, a GPU and the like) for realizing human-computer interaction.
The corresponding control operation is realized on the operation interface on the display screen, the basic information of the detected paddle is input, then the test shaft is stopped and fixed, the upper computer sends a control instruction, the sensor sends the acquired data to the upper computer in real time, and the position of the unbalance point of the paddle at the current position and the unbalance amount of the phase difference can be displayed on the operation interface of the upper computer. The operator increases the number of unbalance numbers on the opposite side of the corresponding position according to the prompt of the display interface, then rotates the paddle by 180 degrees, and then detects again until the unbalance is achieved.
The sensor is connected with a signal input interface of an upper computer through an analog quantity interface or an RS232 communication interface; the testing device further comprises a sliding trolley, the sliding trolley comprises a main beam 9 and a support frame 2 which are connected in an H shape, rollers 3 arranged at the end parts of the support frame 2, a driving machine 4 arranged at the input end of the rollers 3, pulleys on the same side are connected through a wheel shaft 1, a limiting bulge 6 is arranged on the outer side of the support frame 2, a reinforcing part 5 is arranged on the limiting bulge 6, a shock absorber 8 is arranged on the reinforcing part 5, a connecting part 7 is arranged on the main beam 9, and the base is limited on the sliding trolley through the connecting part 7 and the shock absorber 8.
The mounting joint is connected with the testing shaft through an inner ring of the wedge-shaped bearing, and the propeller blade is mounted on the special tool and then connected with the testing shaft through the wedge-shaped bearing. And the upper computer controls and collects signals of the mechanical installation detection part in real time, and the position of the unbalance amount of the aviation propeller blade is displayed through an operation interface.
The base is fixed on the connecting piece and the shock absorber through bolts, and the upper computer controls the driving machine to drive the roller to move in the linear direction through the gear (not shown in the figure). Through a pre-programmed driving circuit, a regular or irregular pulse current is intermittently output to the driving motor, so that the displacement direction and the distance of the sliding trolley can be effectively limited. The simulation device is used for simulating the operation data of the propeller blades in different use environments and irregularly shaking like a ship deck.
