Specific embodiments
[0023] Referring to Figures 1 to 7 , a stator and rotor core processing and detection mechanism for a new energy vehicle involved in the present utility model includes a bottom plate 1. The upper surface of the bottom plate 1 is fixedly connected with a guide plate 2. The upper surface of the bottom plate 1 is fixedly connected with a lifting bracket 3. The inner wall of the lifting bracket 3 is in contact with the surface of the guide plate 2. The upper surface of the lifting bracket 3 is fixedly connected with an adjusting bracket 4. Limiting rings 5 are arranged in a fitting manner on both the upper and lower sides of the lifting bracket 3. The inner walls of the limiting rings 5 and the bottom of the adjusting bracket 4 are both fixedly connected with sliders 6. The surfaces of the sliders 6 are in contact with the inner wall of the lifting bracket 3. Mounting holes 7 are formed inside the sliders 6. Displacement sensors 8 are fixedly connected to the inner walls of the mounting holes 7. The upper surface of the bottom plate 1 is fixedly connected with a main board 9. The lifting bracket 3, the adjusting bracket 4, and the displacement sensor 8 are all electrically connected to the main board 9.
[0024] Further, the lifting bracket 3 includes a sliding sleeve 3.1. The inner wall of the sliding sleeve 3.1 contacts the surface of the guide plate 2. A first cross plate 3.2 is fixedly connected to the left side of the sliding sleeve 3.1. First electric push rods 3.3 are fixedly connected to the bottom of the first cross plate 3.2 and the upper surface of the bottom plate 1 respectively. Second cross plates 3.4 are fixedly connected to the right side of the sliding sleeve 3.1 and the bottom of the adjusting bracket 4 respectively. Through the cooperation of the sliding sleeve 3.1 and the guide plate 2, the first cross plate 3.2 and the second cross plate 3.4 can only move up and down. A strip hole 3.5 is formed in the interior of the second cross plate 3.4. The inner wall of the strip hole 3.5 contacts the surface of the slider 6. The upper and lower sides of the second cross plate 3.4 contact the surface of the limiting ring 5. Through the limiting ring 5, the slider 6 cannot move up and down in the strip hole 3.5. At the same time, the slider 6 can move horizontally in the strip hole 3.5. The first electric push rod 3.3 is electrically connected to the main board 9. The first cross plate 3.2 is controlled to move up and down through the first electric push rod 3.3.
[0025] Further, the adjusting bracket 4 includes a second electric push rod 4.1. The bottom of the second electric push rod 4.1 is fixedly connected to the upper surface of the second cross plate 3.4. The top of the second electric push rod 4.1 is fixedly connected to an octagonal block 4.2. The second electric push rod 4.1 is used to control the octagonal block 4.2 to move up and down. A first hinge 4.3 is fixedly connected to the surface of the octagonal block 4.2. A first connecting column 4.4 is fixedly connected to the side surface of the first hinge 4.3. Second hinges 4.5 are fixedly connected to one end of the first connecting column 4.4 and the upper surface of the slider 6 respectively. When the octagonal block 4.2 moves upward, through the cooperation of the first hinge 4.3, the second hinge 4.5, the first connecting column 4.4, the slider 6, the limiting ring 5 and the strip hole 3.5, the distance between the displacement sensor 8 and the second electric push rod 4.1 is reduced. When the octagonal block 4.2 moves downward, through the cooperation of the first hinge 4.3, the second hinge 4.5, the first connecting column 4.4, the slider 6, the limiting ring 5 and the strip hole 3.5, the distance between the displacement sensor 8 and the second electric push rod 4.1 is increased.
[0026] Further, a second connecting column 10 is fixedly connected to the bottom of the second cross plate 3.4. A support ring 11 is fixedly connected to the bottom of the second connecting column 10. A hemispherical block 12 is fixedly connected to the upper surface of the support ring 11. When the displacement sensor 8 moves above the hemispherical block 12, if the value detected by the displacement sensor 8 is equal to the set value, it indicates that the displacement sensor 8 is not damaged. If the value detected by the displacement sensor 8 is not equal to the set value, it indicates that the displacement sensor 8 is damaged. Furthermore, through the cooperation of the second connecting column 10, the support ring 11 and the hemispherical block 12, the displacement sensor 8 can be automatically calibrated, making it more convenient for the user to repair the displacement sensor 8.
[0027] Further, the number of displacement sensors 8 is eight, and the eight displacement sensors 8 are symmetrically distributed with the adjusting bracket 4 as the center.
[0028] Furthermore, reinforcing blocks 13 are fixedly connected to the left and right sides of the sliding sleeve 3.1, the bottom of the first cross plate 3.2, and the bottom of the second cross plate 3.4. The reinforcing blocks 13 make the fixation between the first cross plate 3.2, the sliding sleeve 3.1, and the second cross plate 3.4 more firm.
[0029] The working principle of a stator and rotor core processing and detection mechanism for a new energy vehicle of the present utility model is as follows: First, install the bottom plate 1 on the production line for stator and rotor core processing. Then, raise the displacement sensor 8 to the initial position through the first electric push rod 3.3. Next, adjust the distance between the displacement sensor 8 and the second electric push rod 4.1 according to the diameter of the stator and rotor core. When adjusting the distance between the displacement sensor 8 and the second electric push rod 4.1, first control the octagonal block 4.2 to move up or down through the second electric push rod 4.1. Then, when the octagonal block 4.2 moves up, through the cooperation of the first hinge 4.3, the second hinge 4.5, the first connecting column 4.4, the slider 6, the limiting ring 5, and the strip-shaped hole 3.5, the distance between the displacement sensor 8 and the second electric push rod 4.1 is reduced. When the octagonal block 4.2 moves down, through the cooperation of the first hinge 4.3, the second hinge 4.5, the first connecting column 4.4, the slider 6, the limiting ring 5, and the strip-shaped hole 3.5, the distance between the displacement sensor 8 and the second electric push rod 4.1 is increased. After the distance between the displacement sensor 8 and the second electric push rod 4.1 is adjusted, move the stator and rotor core to be detected to below the displacement sensor 8 through the conveying mechanism on the production line. Then, make the displacement sensor 8 contact the stator and rotor core through the first electric push rod 3.3, and transmit the data measured by the displacement sensor 8 to the industrial control computer through the main board 9. Then, judge whether the height of the stator and rotor core is qualified according to the data measured by the displacement sensor 8.
[0030] In addition, it should be noted that the above specific implementation manner is only an optimized solution of this patent. Any modification or improvement made by those skilled in the art based on the above concept is within the protection scope of this patent.
