[0028] The specific implementation process of the utility model is as follows: when the servo transformer high temperature test device needs to be used, the setting of the roller 4 makes it convenient for the operator to push the temperature rise test box 1 to move. When the temperature rise test box 1 moves to the specified position, the servo motor 5 is started to drive the output shaft to rotate, so as to drive the bevel gear 1 6 to rotate.

In this process, when the telescopic end of the hydraulic cylinder 14 moves, it can drive the moving cylinder 17 to move, and the inner wall of the positioning hole 16 squeezes the card ball 19 to push the top plate 18 to move, and the spring 20 is deformed, and finally the card ball 19 is separated from the positioning hole 16. Under the action of force, the card ball 19 slides along the inner wall of the temperature rise test box 1. When the card ball 19 slides into the next positioning hole 16, the spring 20 restores the deformation to push the card ball 19 into the positioning hole 16, and the position of the support platform 15 is refined. When testing the servo transformer, it needs to be placed at room temperature for 2 hours, and then continuously tested for 72 hours at 85±2℃.
