[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0020] As Figures 1-5 shown, a stator electrical test clamping device includes a workbench 1 and a wire body 2. The stator 3 is located on the wire body 2 and can move along the wire body 2. The wire body 2 is a prior art and is well-known to those skilled in the art, so it will not be elaborated here. An electrical measurement device 4 is provided on the upper side of the workbench 1. The electrical measurement device 4 includes a fixed seat 8 fixed to the upper side of the workbench 1 by bolts. A linear module 7 is fixed to the upper side of the fixed seat 8 by bolts. The linear module 7 is a prior art and will not be elaborated here. A sliding table 6 is slidably connected back and forth in the linear module 7, and the linear module 7 can push the sliding table 6 to move back and forth. An electrical measurement component 5 is provided at one end of the sliding table 6 close to the stator 3. The electrical measurement component 5 includes a first electrical measurement part 9, a second electrical measurement part 10, and a temperature measurement part 11. The first electrical measurement part 9, the second electrical measurement part 10, and the temperature measurement part 11 are arranged in sequence from top to bottom

[0021] During use, the electrical measurement device 4 is connected to a test device located outside the clamping device. The wire body 2 moves the stator 3 to directly in front of the electrical measurement device 4. The linear module 7 pushes the slider to move forward until the electrical measurement component 5 contacts the stator 3. Then, the test device operates, enabling the first electrical measurement unit 9 to perform electrical measurement on the three-phase terminals of the busbar of the stator 3, and the second electrical measurement unit 10 to perform electrical measurement on the iron core of the stator 3, achieving synchronous measurement of the three-phase terminals of the busbar and the iron core of the stator 3, improving the working efficiency of the stator electrical test clamping device. At the same time, the temperature measurement unit 11 monitors the temperature of the iron core of the stator 3, enabling the electrical measurement work to be within a suitable test range and ensuring the accuracy of the electrical measurement;

[0022] In this embodiment, the first electrical measurement unit 9 includes a mounting seat 16 mounted on the upper side of the end of the sliding table 6 by bolts. The front side of the mounting seat 16 is mounted with a first cylinder 15 by bolts. Two clamping blocks 12 are symmetrically mounted on the front side of the first cylinder 15 up and down by bolts. The two clamping blocks 12 can move towards each other under the action of the first cylinder 15. A plurality of electrical measurement heads 14 are symmetrically hinged on the opposite sides of the ends of the two clamping blocks 12. One end of the electrical measurement head 14 away from the stator 3 is provided with a spring 13. Both ends of the spring 13 are connected to the electrical measurement head 14 and the clamping block 12 respectively to push the ends of the two electrical measurement heads 14 without the spring 13 to rotate and approach each other;

[0023] During use, the first cylinder 15 controls the two clamping blocks 12 to move towards each other, clamping the three-phase terminals of the busbar of the stator 3 with the upper and lower rows of electrical measurement heads 14. At the same time, because the three-phase terminals of the busbar are not flat enough and the consistency is not good, in order to ensure the accuracy of the electrical measurement, under the action of the spring 13, the electrical measurement heads 14 clamp the three-phase terminals according to the actual ends, and under the action of an external detection device, the three-phase terminals of the busbar of the stator 3 are detected, so as to improve the detection accuracy of the first electrical measurement unit 9 for the three-phase terminals of the busbar of the stator 3.

[0024] In this embodiment, evenly distributed sawteeth are provided on the opposite sides of the electrical measurement head 14 close to the stator 3. During use, the serrated structure can increase the connection strength between the electrical measurement head 14 and the stator 3, further improving the detection effect of the electrical measurement head 14 on the stator 3.

[0025] In this embodiment, the second electrical measurement unit 10 includes a mounting plate 20 fixed to the lower side of the end of the sliding table 6 by bolts. On the upper side of the end of the mounting plate 20, a vertical plate 18 is fixed by bolts and a triangular plate. On the front side of the vertical plate 18, a connecting block 19 is fixed by bolts. At the left and right ends of the upper side of the connecting block 19, two voltage-conducting plates 17 are symmetrically hinged. A blade 27 is clamped inside the voltage-conducting plate 17. The sharp end of the blade 27 is located in front of the voltage-conducting plate 17. Below the voltage-conducting plate 17, a spring fixing member 25 fixed to the front side of the connecting block 19 by bolts is provided. On the upper side of the front end of the spring fixing member 25, a spring 26 is provided. Two ends of the spring 26 are respectively connected to the lower side of the voltage-conducting plate 17 and the upper side of the spring fixing member 25;

[0026] During use, the linear module 7 pushes the sliding table 6 to move towards the stator 3 so that the sharp end of the blade 27 contacts the iron core of the stator 3. At the same time, under the action of the spring 26, the blade 27 moves downward to penetrate the insulating paint on the outer wall of the iron core of the stator 3, so that the blade 27 contacts the iron core, so as to achieve the purpose of electrical measurement of the iron core.

[0027] In this embodiment, the temperature measurement unit 11 includes a second cylinder 21 fixed to the lower side of the mounting plate 20 by bolts. The output end of the second cylinder 21 faces the stator 3 and is fixed with a connecting plate 22 by bolts. On the front side of the connecting plate 22, a limiting block 24 is installed by bolts and connecting columns, and a temperature sensor 23 is embedded in the limiting block 24;

[0028] During use, the second cylinder 21 pushes the connecting plate 22 to move towards the stator 3, so that the front side of the limiting block 24 fits against the outer side of the iron core of the stator 3. Then, under the action of the temperature sensor 23, the temperature of the iron core of the stator 3 is detected, so that when the stator 3 is being detected, its own temperature is within the standard range to ensure the detection accuracy of the stator 3. At the same time, the limiting block 24 can well protect the temperature sensor 23 and prevent the test end of the temperature sensor 23 from being damaged due to long-term force.

[0029] In this embodiment, one end of the limiting block 24 close to the stator 3 is arc-shaped, which can make the limiting block 24 fit well with the iron core during use.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
