The top of the second electric telescopic rod 4 is fixedly connected to the insulating plate 5, and the vertical movement effect of the insulating plate 5 drives the conductive block 13 to contact or release the contact effect with the conductive plate 8. The bottom of the insulating plate 5 is fixedly connected to the conductive block 13, and the circuit is connected by contacting the conductive block 13 with the conductive plate 8. A clamping assembly 9 is provided on the top of the workbench 2, and the motor is clamped and fixed by the clamping assembly 9 to prevent the motor from displacement during testing.

[0035] Reference Figure 1 and Figure 4 The clamping assembly 9 includes a clamping plate 92, which is symmetrically arranged in two groups. The clamping surface of the clamping plate 92 is provided with a rubber insulating layer. The front side of the clamping plate 92 is hinged with a hinged rod 93, which is symmetrically distributed in two groups. The clamping plate 92 is driven to move by the moving effect of the hinged rod 93. The front end of the hinged rod 93 is hinged with a slider 94.

The inner wall of the slider 94 is provided with a limiting assembly 97. The slider 94 is limited by the limiting assembly 97, so that the clamping plate 92 remains fixed.

[0036] Reference Figure 3 and Figure 5A first electric telescopic rod 3 is fixedly connected to the top right end of the base 1. By starting the first electric telescopic rod 3, the workbench 2 is driven to move horizontally. A condenser 10 is fixedly connected to the inner wall of the workbench 2. A plurality of through holes are arranged on the workbench 2. The condenser 10 is S-shaped. The condenser 10 has a circulating heat dissipation effect on the workbench 2 and the motor.

An electric fan 12 is arranged on the top inner wall of the base 1. By starting the electric fan 12, the cold air around the condenser 10 is blown to the top of the workbench 2 to further dissipate heat for the motor.

[0037] Reference Figure 4 and Figure 6 The limiting component 97 includes a card block 971, and the outer wall of the card block 971 is elastically connected to the inner wall of the slider 94 through a spring 972. Through the elastic force of the spring 972, the card block 971 always maintains a card connection effect with the card slot 974 when not affected by external force, thereby limiting the slider 94. A pull rod 973 is fixedly connected to the outer wall of the card block 971, and a card slot 974 is opened on the left side of the fixed rod 95. There are multiple groups of card slots 974, and the card slots 974 are connected to the card block 971 at different positions through the multiple groups of card slots 974, thereby limiting the slider 94 at different positions.

The condenser 10 is circulated and cooled by connecting the connecting pipe 11 to an external refrigerator.

[0040] Reference Figure 6 One end of the spring 972 is fixedly connected to the inner wall of the slider 94, and the other end of the spring 972 is fixedly connected to the outer wall of the block 971. Through the fixing effect of the spring 972, the block 971 remains fixed to prevent the block 971 from falling off.

[0041] Reference Figure 4The top of the workbench 2 is fixedly connected to the bottom end of the fixing rod 95, and the fixing effect of the fixing rod 95 prevents the fixing rod 95 from falling off. The outer periphery of the guide rod 96 is slidably connected to the inner wall of the clamping plate 92, and the clamping plate 92 is guided by the guide rod 96 to prevent the clamping plate 92 from deviating when moving.

[0042] Reference Figure 6 The outer wall of the block 971 is slidably connected to the inner wall of the slider 94. Through the sliding effect of the block 971, the block 971 and the slot 974 are engaged or released. The outer wall of the block 971 is engaged with the inner wall of the slot 974. Through the engagement of the block 971 and the slot 974, the fixing rod 95 limits the slider 94.

[0043] Working principle: When the staff needs to perform a voltage test on the motor, the staff places the motor on the top of the conductive plate 8, connects the connecting pipe 11 to the refrigerator, and pulls the pull rod 973 outward, so that the block 971 releases the clamping effect with the slot 974, and at the same time releases the limiting effect on the slider 94, and slides the slider 94 away from the motor, so that the two sets of hinged rods 93 drive the clamping plate 92 to slide along the inner wall of the guide rod 96 toward the motor, clamping and fixing the motor, and loosening the pull rod 973, so that the block 971 is clamped with the slot 974 under the elastic force of the spring 972, thereby limiting the slider 94 and keeping the clamping plate 92 in a fixed clamping state.

[0044] After the motor is fixed, the staff connects the lead of the motor to the top of the conductive rod 6 and starts the first electric telescopic rod 3 at the same time, driving the workbench 2 to slide to the left along the outer wall of the support rod 14, so that the conductive rod 6 contacts the contact block 7, thereby realizing power-on with the withstand voltage tester. The staff starts the second electric telescopic rod 4 to drive the insulating plate 5 to move downward, so that the conductive block 13 contacts the conductive plate 8, thereby realizing the passage of the withstand voltage test circuit. At this time, the motor can be subjected to a withstand voltage test by the withstand voltage tester.

[0045] When the voltage test of the motor is completed, the staff starts the refrigerator, and the condenser 10 produces a circulating cooling effect through the connecting pipe 11, which has a heat dissipation effect on the workbench 2 and the bottom of the motor. The staff starts the electric fan 12, so that the electric fan 12 blows the cold air around the condenser 10 from the through hole opened on the workbench 2 to the top of the workbench 2, which further has a heat dissipation effect on the motor and the workbench 2, making it convenient for the staff to test the subsequent motors to be tested.
