And during the subsequent testing process, even when the gantry 701 slides on the top end face of the test bench 2 to switch the test station by overcoming the elastic force of the spring rod 706 under the continuous pressure of the cylinder 6, the electrical connection between the servo driver body 105 and the motor 13 can still be maintained to comprehensively test the actual operating conditions of the servo driver body 105 under different ambient temperatures; Please refer to Figure 6 As shown in the figure, a flipping and switching assembly 8 is rotatably installed at the bottom of the test bench 2. The flipping and switching assembly 8 includes a bearing seat 801, a rotating rod 802, and a driven gear 803. The bearing seats 801 are symmetrically fixed to the middle of the bottom of the test bench 2, and a rotating rod 802 is rotatably installed inside the bearing seat 801. The end of the rotating rod 802 is coaxially connected with a driven gear 803, and the driven gear 803 is rotationally driven by a driving gear plate 103 on the inner wall of the notch of the L-shaped ejector rod 102 through a transmission gear 3. The flipping and switching assembly 8 further includes a heat sink 804, a fan 805, a silicone grease sheet 806, and a semiconductor refrigeration sheet 807. A heat sink 804 is fixed to the outer edge of one end of the rotating rod 802, and a fan 805 is embedded in the middle of the heat sink 804. A silicone grease sheet 806 is adhered to the end of the heat sink 804, and the heat sink 804 is connected to the semiconductor refrigeration sheet 807 through the silicone grease sheet 806; The specific operations are as follows. When the carriage 101 loaded with the servo drive body 105 to be tested is located above the right through slot 4 of the test bench 2, at this time, the cold surface of the semiconductor refrigeration sheet 807 faces upward, and the temperature dissipated from its hot surface is conducted to the heat sink 804 and further assisted in heat dissipation by the fan 805. By ensuring the efficient heat dissipation of its hot surface, the refrigerating capacity of the cold surface is improved. When the cold surface of the semiconductor refrigeration sheet 807 faces upward, the servo drive body 105 located in the shield 107 is in the low-temperature aging test station. The adjustable power supply 11 is used to adjust parameters such as the current and voltage of the servo drive body 105 in the low-temperature environment to complete the static test of the current servo drive to be tested in the low-temperature environment. When the carriage 101 moves to above the left through slot 4 under the push of the cylinder 6, at this time, the L-shaped ejector rod 102 at the side end of the carriage 101 is in contact with the V-shaped pins 703 on both sides of the gantry 701 to establish an electrical connection with the motor 13. At the same time, it further rotates and drives the driven gear 803 at the end of the rotating rod 802 located inside the bearing seat 801 through the meshing of the driving tooth plate 103 on the inner wall of the notch and the transmission gear 3 at the side end of the middle part of the test bench 2. As a result, the semiconductor refrigeration sheet 807 connected to the side end of the rotating rod 802 rotates clockwise by 180 degrees. At this time, the hot surface of the semiconductor refrigeration sheet 807 is switched to face upward. By stopping the operation of the fan 805, the servo drive body 105 in the shield 107 can be in the high-temperature aging test station through heat radiation to complete the static test of the current servo drive to be tested in the high-temperature environment. Through the cooperation of the movement of the test fixture 1 and the flipping and switching assembly 8, during the movement of the carriage 101 driven by the cylinder 6 on the top of the test bench 2, while establishing an electrical connection between the servo drive body 105 and the motor 13, the driving tooth plate 103 realizes the 180-degree flipping of the semiconductor refrigeration sheet 807 through the meshing transmission of the transmission gear 3 and the driven gear 803, so that the servo drive body 105 can be switched between the low-temperature test station and the high-temperature test station through the switching of the cold and hot double sides of the semiconductor refrigeration sheet 807, and the electrical connection between the servo drive body 105 and the motor 13 is always maintained during the switching process. The adjustable power supply 11 is used to adjust parameters such as the current and voltage of the servo drive body 105 in different environments to complete the static test of the current servo drive to be tested in different environments; Please refer to Figure 7 , four surrounding sides of the bottom of the test bench 2 are fixedly connected with supporting feet 9, and the roots of the supporting feet 9 are bolt-fixed to the base 10. An adjustable power supply 11 is arranged at the side end of the base 10, and the adjustable power supply 11 is electrically connected to the servo drive body 105 through a power cord. An auxiliary bench 12 is fixedly connected to the side end of the base 10, and a motor 13 is bolt-fixed to the top of the auxiliary bench 12. The output end of the motor 13 is fixedly connected with a rotating shaft 14, and the rotating shaft 14 is connected to the hysteresis brake 15 through a coupling; The specific operations are as follows. During actual testing, the excitation current of the input hysteresis brake 15 is controlled to adjust the generated output torque, and the adjustable power supply 11 is used to control the frequent on-off of the motor 13, so as to dynamically test whether the servo drive body 105 to be tested can maintain stable output under the conditions of high load or frequent start-stop of the motor 13, and thus expose the potential risks of the servo drive body 105 in the real working environment.

[0020] In summary, when using this driver aging test device, the servo driver body 105 to be tested is clamped in the middle notch of the positioning seat 104 and then the shield 107 is flipped and buckled. The air cylinder 6 is started and the sliding seat 101 is pushed to slide on the top end face of the test bench 2 until the end of the L-shaped ejector rod 102 presses the contact roller 704 at one end of the V-shaped pin 703, so that the V-shaped pin 703 rotates in the torsion spring seat 702 against the elastic force of the torsion spring and further engages with the sliding pin 711 through the other end slot 705, pulling the movable plug 708 to move downward on the front slide rail 707 of the gantry 701, and then through the docking of the movable plug 708 with the power receiving interface at the front end of the servo driver body 105, an electrical connection between the servo driver body 105 and the motor 13 is established through the connecting wire 709. In actual testing, the output torque generated is adjusted by controlling the excitation current of the input hysteresis brake 15, and the frequent on-off of the motor 13 is controlled by the adjustable power supply 11 to dynamically test whether the servo driver body 105 to be tested can maintain a stable output under the conditions of high load or frequent start-stop of the motor 13, and thus expose the potential risks of the servo driver body 105 in the real working environment. Through the cooperation of the movement of the test fixture 1 and the movable plug-in component 7, the servo driver to be tested can, during the movement driven by the air cylinder 6, automatically realize the docking of the movable plug 708 with the power receiving interface at the front end of the servo driver body 105 through the abutting cooperation between the L-shaped ejector rod 102 at the side end of the sliding seat 101 and the V-shaped pins 703 on both sides of the gantry 701, and then establish an electrical connection between the servo driver body 105 and the motor 13 through the connecting wire 709 for dynamic testing. And during the subsequent testing process, even when the gantry 701 slides on the top end face of the test bench 2 to switch the test station by overcoming the elastic force of the spring rod 706 under the continuous pressure of the air cylinder 6, it can still maintain the electrical connection between the servo driver body 105 and the motor 13 to comprehensively test the actual operating conditions of the servo driver body 105 under different ambient temperatures. When the sliding seat 101 loaded with the servo driver body 105 to be tested is located above the right through slot 4 of the test bench 2, at this time, the cold surface of the semiconductor refrigeration sheet 807 faces upward, and the temperature dissipated from its hot surface is conducted to the heat sink 804 and further assisted in heat dissipation by the fan 805, and the cooling capacity of the cold surface is increased by ensuring the efficient heat dissipation of its hot surface. When the cold surface of the semiconductor refrigeration sheet 807 faces upward, the servo driver body 105 in the shield 107 is in the low-temperature aging test station, and the current, voltage and other parameters of the servo driver body 105 in the low-temperature environment are adjusted by the adjustable power supply 11 to complete the static test of the current servo driver to be tested in the low-temperature environment. And when the sliding seat 101 is pushed by the air cylinder 6 to move above the left through slot 4, at this time, while establishing an electrical connection with the motor 13 through the abutting cooperation between the L-shaped ejector rod 102 at the side end of the sliding seat 101 and the V-shaped pins 703 on both sides of the gantry 701,Further, through the engagement of the driving tooth plate 103 on the inner wall of the notch with the transmission gear 3 at the middle side end of the test bench 2, rotational transmission is carried out towards the driven gear 803 at the end of the rotating rod 802 inside the bearing seat 801, thereby causing the semiconductor refrigeration sheet 807 connected to the side end of the rotating rod 802 to rotate clockwise by 180 degrees. At this time, the hot surface of the semiconductor refrigeration sheet 807 is switched upwards. By stopping the operation of the fan 805, the servo driver body 105 inside the shield 107 can be placed in the high-temperature aging test station through the way of heat radiation, so as to complete the static test of the current servo driver to be tested in a high-temperature environment. Through the cooperation of the movement of the test fixture 1 and the flipping and switching assembly 8, during the movement of the sliding seat 101 at the top of the test bench 2 driven by the cylinder 6, while establishing the electrical connection between the servo driver body 105 and the motor 13, the driving tooth plate 103 realizes the 180-degree flipping of the semiconductor refrigeration sheet 807 through the meshing transmission with the driven gear 803 via the transmission gear 3, enabling the servo driver body 105 to switch tests between the low-temperature test station and the high-temperature test station through the switching of the hot and cold double sides of the semiconductor refrigeration sheet 807, and always maintaining the electrical connection between the servo driver body 105 and the motor 13 during the switching process. The parameters such as the current and voltage of the servo driver body 105 in different environments are adjusted through the adjustable power supply 11 to complete the static test of the current servo driver to be tested in different environments.
