[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4A fixing fixture for applying adhesive to electric vehicle motor coils includes a base 1, a drive device, a fixing frame 2, a height adjustment device, a clamping seat 3, and a clamping device. A placement seat 4 is fixedly installed on the top wall of the base 1, and a support rod 5 is installed on the top of the placement seat 4. Two sets of fixing frames 2 are symmetrically installed on the top of the base 1 via the drive device. The clamping seats 3 are installed inside the fixing frames 2 via the height adjustment device. The clamping device includes a groove 6, a support cylinder 7, a cylindrical groove 8, a clamping block 9, and a spring 10. Multiple sets of grooves 6 are formed on one side wall of each of the two sets of clamping seats 3. The support cylinder 7 is fixedly installed inside the groove 6. The cylindrical groove 8 is formed at the end of the support cylinder 7 away from the groove 6. The clamping block 9 is slidably installed inside the cylindrical groove 8. The clamping block 9 is connected to the side wall of the cylindrical groove 8 via the spring 10. In this embodiment, during use, the height adjustment device is used to adjust the two sets of... The height of the clamping seat 3 is adjusted so that it is positioned at an appropriate height for the motor coil. The motor coil is placed on the placement seat 4 through the support rod 5. The two sets of fixed frames 2 are moved towards the center by the drive device until the fixed frames 2 drive the two sets of clamping seats 3 close to the motor coil. When the clamping seat 3 moves to the appropriate position, the clamping block 9 will extend outward from the cylindrical groove 8 under the action of the spring 10. As the clamping seat 3 continues to approach the motor coil, the clamping block 9 will be pushed into the cylindrical groove 8, compressing the spring 10. With the compression of the spring 10, it will generate a reverse elastic force. This elastic force will be transmitted to the motor coil through the clamping block 9, forming a stable clamping force. The elastic force provided by the spring 10 ensures that the motor coil will not be displaced or vibrated during processing and remains stable. Because the spring 10 has a certain elasticity, it can automatically adapt to slight changes in the motor coil, ensuring a good clamping effect even when switching between coils of different shapes or sizes.
[0025] In practical use, to further facilitate the driving of the two sets of clamping plates to move closer together to achieve clamping action, in this embodiment, the driving device includes a groove 11, a bidirectional screw 12, a slider 13, and a drive motor 14. The groove 11 is horizontally opened at the top of the base 1. The bidirectional screw 12 is rotatably installed in the groove 11. One end of the bidirectional screw 12 passes through the side wall of the groove 11 and is fitted with the drive motor 14. The sliders 13 are threaded onto both the left and right ends of the bidirectional screw 12. The top walls of the two sets of sliders 13 are fixedly connected to the side walls of the corresponding fixing frames 2. By controlling the rotation of the bidirectional screw 12 through the drive motor 14, the sliders 13 can be precisely controlled. The movement of the screw 12 brings the two sets of clamping seats 3 closer together. The combined design of the bidirectional screw 12 and the slider 13 makes the clamping action more stable and reliable. The slider 13 is threaded on the bidirectional screw 12, which ensures that the slider 13 will not jump or jam during the movement, thus ensuring the stability of the clamping. The design of the bidirectional screw 12 allows the slider 13 to move at both ends of the screw, so that the distance between the two sets of clamping plates can be adjusted as needed, which can achieve both clamping and loosening, increasing the flexibility of the equipment. By controlling the rotation of the bidirectional screw 12 through the drive motor 14, automated or semi-automated clamping operations can be achieved, reducing the complexity of manual operation and improving operating efficiency.
[0026] In practical use, to further facilitate the adjustment of the height of the two sets of clamping seats 3, in this embodiment, the height adjustment device includes an electric telescopic rod 15 and a moving block 16. The electric telescopic rod 15 is installed on the top wall of the fixed frame 2. The output end of the electric telescopic rod 15 passes through the top wall of the fixed frame 2 and extends into its inner cavity where the moving block 16 is installed. The moving block 16 is fixedly connected to the side wall of the corresponding clamping seat 3. When the two sets of electric telescopic rods 15 are activated, the output ends of the two sets of electric telescopic rods 15 drive the moving block 16 to rise and fall within the fixed frame 2. By adjusting the telescopic length of the electric telescopic rod 15, the height of the two sets of clamping seats 3 can be adjusted. It can be adjusted before the clamping action to make the height of the two sets of clamping seats 3 match the position of the motor coil, or it can be adjusted after the clamping action to adjust the height of the clamped and fixed motor coil to adapt to the processing requirements of the motor coil gluing action.
[0027] In practical use, to further prevent the clamping block 9 from damaging the side wall of the motor coil, in this embodiment, the end of the clamping block 9 is designed with rounded corners. The rounded corner design can reduce the sharp edges when the clamping block 9 contacts the side wall of the motor coil, thereby reducing the risk of scratches or indentations on the coil surface. The rounded corner design can disperse the pressure when the clamping block 9 contacts the side wall of the motor coil, reducing local stress concentration. This can avoid damage or deformation of the coil surface caused by excessive local pressure.
[0028] In practical use, to further facilitate adaptation to the outer wall of the motor coil, in this embodiment, the clamping seat 3 is designed in an arc shape. The arc-shaped clamping seat 3 can better fit the outer wall of the motor coil, providing a larger contact area, thereby improving the stability and reliability of clamping. This design makes the clamping more uniform and avoids clamping instability caused by local stress concentration. Compared with the straight design, the arc design can disperse the clamping force, reduce local pressure, and avoid damage to the outer wall of the motor coil.
[0029] In practical use, to further improve the clamping effect, in this embodiment, a rubber pad is installed at the end of the clamping block 9. The rubber pad has a good coefficient of friction, which can increase the friction between the clamping block 9 and the clamped object. This design makes the clamping more secure and reduces the possibility of the object sliding during the clamping process. The rubber pad is soft and has a certain elasticity, which can avoid scratches or damage caused when the hard clamping block 9 directly contacts the surface of the object.
[0030] In practical use, to further ensure the stability and accuracy of the drive motor 14, in this embodiment, the drive motor 14 is a servo motor. The servo motor can control the position, speed and torque with high precision. The servo motor adopts closed-loop control, which has good stability and can avoid problems such as stalling and vibration, thus ensuring the stability and accuracy of the drive motor 14.
[0031] In actual use, the extension and retraction of the clamping block 9 are further guided. In this embodiment, guide strips 17 are fixedly installed at both the front and rear ends of the clamping block 9, and guide grooves 18 are opened at both the front and rear ends of the cylindrical groove 8. The guide grooves 18 and the guide strips 17 are slidably connected. The design of the guide strips 17 and the guide grooves 18 can ensure that the clamping block 9 slides smoothly in the cylindrical groove 8, reduce the shaking or jamming phenomenon during the sliding process, improve the smoothness and reliability of the sliding, and further guide the extension and retraction of the clamping block 9.
