[0029] The working principle and use process of this utility model: When the device is actually used:

[0030] When the device is working, the operator controls the servo motor 21 through the control panel 16 to drive the lifting screw 22 and then the threaded sleeve 23 to adjust the height, so that the height of the test base 302 is lowered. At this time, the operator removes the guide rod 304 along the circular groove 308 on the test base 302, and then places the spring to be tested on the mounting seat 305, and aligns the center position of the spring to be tested with the mounting groove 309 on the mounting seat 305. At this time, the operator inserts the removed guide rod 304 back along the circular groove 308 and the mounting groove 309, so that the spring to be tested on the mounting seat 305 is placed on the guide rod;

[0031] The operator then controls the servo motor 21 via the control panel 16, driving the lifting screw 22 and, in turn, the threaded sleeve 23 to adjust the height, lowering the test base 302 until the second pressure sensor 311 at the bottom contacts the spring to be tested, thereby placing the spring in the test position.

[0032] The operator then controls the servo motor 21 through the control panel 16 to drive the lifting screw 22 and then the threaded sleeve 23 to adjust the height, causing the height of the test base 302 to descend, and performing a compression test on the spring to be tested. When the kinetic energy converted from the elastic potential energy of the spring to the pressure parameter generated by the second pressure sensor 311 reaches the set parameter, the operator can measure the current compression of the spring through an external measuring device, and through several tests with different pressure parameter settings, obtain the corresponding compression data, and then determine whether the elastic performance of the current test spring meets the requirements;

[0033] The overall design enables the device to be mounted on the guide rod 304, compared with the traditional equipment that directly presses down to test the compression elastic performance of the spring, which can avoid the safety risks caused by the spring bending and ejecting during the compression process, thereby greatly improving the testing safety of the equipment.
