On the contrary, during impact, the support tray 1051 and the ball 1054 are completely closed and placed inside the base 105, which does not affect the impact.

[0030] In order to facilitate the support and placement of the transmission main shaft on the surface of the support tray 1051 through the rolling component without generating friction, in this embodiment, preferably, the rolling component includes a rolling groove 1055 opened inside the support tray 1051, and a ball 1054 rolls inside the rolling groove 1055.

[0031] The working principle and use process of the present invention are as follows: when using the impact test device for the transmission spindle, the main body 100 of the impact test device is stably placed in the use position directly by touching the ground with the bottom end of the test base 101. After the main body 100 of the impact test device is stably placed, the transmission spindle is placed on the surface of the base 105 again and fixed. At this time, the impact cylinder 103 is moved to drive the pressure sensor 104 and the impact plate 106 to move downward until the impact plate 106 moves downward and impacts the surface of the transmission spindle. At this time, the pressure sensor 104 is subjected to the impact force and the impact data is displayed on the display screen on the surface of the test base 101, thereby facilitating the impact test of the transmission spindle through the main body 100 of the impact test device.

[0032] Then when the impact resistance test device main body 100 is placed on the surface of the base 105, the angle of the downward clamping plate 1024 is adjusted according to the model of the impact-resistant transmission main shaft, the threaded rod 1023 is rotated at the end of the threaded rod 1023 inside the connecting plate 1022, the threaded rod 1023 is rotated at the end of the moving adjusting plate 1028 inside the bearing in situ and drives the moving adjusting plate 1028 to move downward, the moving adjusting plate 1028 moves downward to drive the downward clamping plate 1024 to a certain angle, and the slider 1027 is slid inside the sliding groove 1029, and the other side of the downward clamping plate 1024 is stably supported by the supporting rod 1026, so that the downward clamping plate 1024 is adjusted to the appropriate angle of the transmission main shaft. When the connecting plate 1022 and the downward clamping plate 1024 are moved downward by the downward cylinder 1025, the downward clamping plate 1024 is tightly pressed on the surface of the transmission main shaft, so that the transmission main shaft of different types is clamped and fixed more conveniently, and the convenience of clamping and fixing of the impact resistance test device main body 100 during impact resistance test of transmission main shafts of different types is improved.

[0033] Finally, before the impact resistance test device main body 100 tests the impact resistance of the transmission main shaft, the support plate 1051 is moved to open in the groove 1052 by the lifting cylinder 1053, until the support plate 1051 and the ball 1054 are opened higher than the inside of the base 105. At this time, when the transmission main shaft is placed on the surface of the base 105, the surface of the transmission main shaft contacts the surface of the ball 1054 and pushes the transmission main shaft to drive the ball 1054 to roll, until the transmission main shaft is rolled and closed and placed, and it is not easy to cause friction damage on the surface of the base 105. Conversely, the same operation is performed to roll it off, and after the transmission main shaft is placed on the surface of the base 105, the support plate 1051 is closed in the groove 1052 again, so that the transmission main shaft is completely closed on the surface of the base 105. Impact, improve the convenience of the impact resistance test device main body 100 during the impact resistance test of the transmission main shaft.
