[0002] A fan bracket is a component used to fix and support a fan. It is usually made of metal or plastic and can ensure the stability of the fan, preventing it from shaking or shifting during operation. A fan bracket hole calibration device is a tool used to calibrate the size and position of the mounting holes on the fan bracket. It is mainly used to ensure the quality of the mounting holes so that the fan can be installed securely.

[0003] However, existing fan bracket bore calibration devices have the following problems when in use:

[0004] To ensure the accuracy of calibration results, the device needs to position the fan bracket when calibrating the fan bracket aperture. However, the existing fan bracket aperture calibration device has insufficient limiting effect, which makes it difficult for the fan bracket to be stably positioned on the device for calibration, thus affecting the calibration effect and reducing the practicality of the device.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing fan bracket aperture calibration device. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a fan bracket aperture calibration device, comprising a base plate 1, a positioning rod 2, an adjusting rod 3, a bracket 4, a support ring 5, a bottom servo motor 6, a transmission rod 7, a sleeve 8, a limiting mechanism 9, a support rod 901, a stop rod 902, a spring 903, a base 10, a lifting sleeve 11, a support plate 12, an upper servo motor 13, a calibration plate 14, and a calibration rod 15. The positioning rod 2, the adjusting rod 3, and the bracket 4 are fixedly mounted sequentially from left to right on the upper surface of the base plate 1. A support ring 5 is fixedly connected to the upper outer wall of the bracket 4, and a bottom servo motor is fixedly installed on the upper surface of the base plate 1 inside the bracket 4. 6. Furthermore, a transmission rod 7 is fixedly installed at the upper end of the output shaft of the bottom servo motor 6. At the same time, a sleeve 8 is sleeved on the outer wall of the transmission rod 7. A limit mechanism 9 is set at equal angles on the outer wall of the sleeve 8. A base 10 is fixedly installed on the inner wall of the bracket 4 on the side of the limit mechanism 9. A lifting sleeve 11 is sleeved on the upper outer wall of the adjusting rod 3. A support plate 12 is movably installed on the lower outer wall of the lifting sleeve 11. An upper servo motor 13 is set on the upper surface of the support plate 12 on the side of the lifting sleeve 11. A calibration plate 14 is fixedly connected to the lower surface of the end of the support plate 12. A calibration rod 15 is fixed at equal angles at the edge of the lower surface of the calibration plate 14.

[0022] The transmission rod 7 and the bracket 4 are rotatably connected, and the transmission rod 7 and the sleeve 8 are threaded together, which makes it easy for the bottom servo motor 6 to drive the transmission rod 7 to rotate stably, so that the sleeve 8 can move vertically relative to the transmission rod 7.

[0023] The limiting mechanism 9 includes a support rod 901, a stop rod 902 and a spring 903. The support rod 901 is movably installed on the outer wall of the sleeve 8, and the end of the support rod 901 is movably provided with the stop rod 902, so that the sleeve 8 can drive the limiting mechanism 9 through the vertical movement of the sleeve 8, thereby allowing the stop rod 902 to fit against the inner wall of the fan bracket to limit the fan bracket.

[0024] The two ends of the support rod 901 form a rotating structure with the sleeve 8 and the abutment rod 902 respectively. The abutment rod 902 and the base 10 are slidably connected. The outer wall of the end of the abutment rod 902 is connected to the outer wall of the side of the base 10 through the spring 903. When the sleeve 8 moves, the sleeve 8 drives the support rod 901, so that the support rod 901 drives the abutment rod 902 to move relative to the base 10, thereby allowing the abutment rod 902 to fit against the inner wall of the fan bracket, and the spring 903 provides elastic support for the abutment rod 902.

[0025] The lifting sleeve 11 and the adjusting rod 3 are threaded together. The support plate 12 and the positioning rod 2 form a sliding structure, which facilitates the vertical movement of the lifting sleeve 11 relative to the adjusting rod 3 when the lifting sleeve 11 rotates. At this time, the support plate 12 slides relative to the positioning rod 2, thereby driving the calibration plate 14 and the calibration rod 15 to move down automatically, which improves the ease of use of the device.

[0026] The lifting sleeve 11 is connected to the support plate 12 via a bearing, and the upper outer wall of the lifting sleeve 11 is connected to the upper outer wall of the output shaft of the upper servo motor 13 via a sprocket mechanism, so that the upper servo motor 13 can drive the lifting sleeve 11 to rotate relative to the support plate 12, so that the lifting sleeve 11 drives the support plate 12 to move vertically when it rotates.

[0027] Working principle: When using this fan bracket aperture calibration device, firstly as follows... Figure 1-4 As shown, the user places the fan bracket onto the support bracket 4 and moves the fan bracket to fit against the support ring 5. Then, the user starts the bottom servo motor 6, which drives the transmission rod 7 to rotate. Subsequently, the sleeve 8 moves upward relative to the transmission rod 7. At this time, the sleeve 8 rotates relative to one end of the support rod 901, causing that end of the support rod 901 to move. Simultaneously, the other end of the support rod 901 rotates relative to the abutment rod 902, pushing the abutment rod 902 to slide relative to the base 10. Then, the abutment rod 902 moves to fit against the fan bracket, compressing the spring 903 and causing it to deform. At this point, the abutment rod 902 fits against the inner wall of the fan bracket, thus completing the limiting of the fan bracket. Therefore, the device enhances the limiting capability, facilitating the stable positioning of the fan bracket on the device for calibration, thereby improving the practicality of the device. The user then starts the upper servo motor 13, which drives the lifting sleeve 11 to rotate via the sprocket mechanism. Next, the lifting sleeve 11 moves vertically downward relative to the adjusting rod 3. Subsequently, the lifting sleeve 11 drives the support plate 12 to move downward, while the support plate 12 slides down relative to the positioning rod 2, thus stabilizing the downward movement of the support plate 12. Then, the support plate 12 drives the calibration plate 14 and calibration rod 15 to move downward. When the calibration rod 15 moves above the fan bracket, the user turns off the upper servo motor 13. At this time, the user observes the relative position of the calibration rod 15 and the fan bracket aperture to determine whether the fan bracket aperture is qualified, thus completing the calibration of the fan bracket aperture. Therefore, the device can automatically adjust the position of the calibration rod 15 to calibrate the fan bracket aperture, improving the ease of use of the device.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
