[0028] Working principle:

[0029] When working, the operator first installs the to-be-tested pusher 9 on the limiting seat 8, and reliably fixes different models of pushers 9 by adjusting the limiting bolt 82. Then the gantry 4 is manually pushed, so that the moving seat 3 stably slides along the guide rail 2 through the guide wheel 31, and the gantry 4 is accurately positioned above the to-be-tested pusher 9. After positioning, the locking bolt 32 is tightened to make the guide wheel 31 closely fit the guide rail 2, so as to ensure that the device remains in a stable state during testing.

[0030] During testing, the pushing force generated by the pusher 9 during work is transmitted to the pressure sensor 5 through the buffer rod 72, and the buffer spring 73 effectively absorbs the impact load, so as to ensure the accuracy of the pressure sensor 5. At the same time, the current transformer 61 monitors the working current of the pusher 9 in real time, and the data acquisition module 62 synchronously collects the signals of the pressure sensor 5 and the current transformer 61, so as to realize accurate measurement and recording of the pushing force and current parameters.

The device can not only measure the static pushing force and dynamic working current of the pusher, but also obtain the stroke characteristic curve and working temperature rise and other parameters through continuous monitoring. The modular design of the limiting seat 8 makes the installation and replacement of different models of pushers 9 more convenient, and significantly improves the detection efficiency. The entire testing process does not need to repeatedly disassemble and move the pusher 9, but only needs to move the gantry 4 to complete multi-station detection, which greatly reduces the labor intensity of the operator.

[0032] The test device realizes efficient and accurate detection of various performance parameters of the pusher 9 through reasonable mechanical structure design and accurate measurement system configuration. The cooperation of the guide rail 2 and the moving seat 3 ensures the accurate positioning of the test position, the buffer assembly 7 effectively protects the measuring element, and the modular limiting seat 8 design enhances the universality and adaptability of the device. The whole system is easy to operate, and the detection items are comprehensive, which can meet various technical requirements of the pusher 9 factory inspection.
