Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-5 This utility model provides an adaptive centering and tightening mechanism, including a fixed plate 1. A lifting component is fixedly installed on one side of the fixed plate 1. A limit spring 3 is provided in the middle of the top of the lifting component. A rotating platform connecting plate 4 is fixedly connected to the bottom of the lifting component. A motor component is provided in the middle of the surface of the rotating platform connecting plate 4. A hollow rotating platform 19 is fixedly connected to the bottom of the rotating platform connecting plate 4. A partition 21 is fixedly connected to the bottom of the hollow rotating platform 19. A first seat groove is provided on both sides of the bottom of the partition 21. A moving mechanism is provided at the bottom of the partition 21. A reset component is provided on both sides of the moving mechanism.

[0022] See Figure 1 and Figure 2Furthermore, the lifting assembly includes two slide rods 5, one side of each slide rod 5 is slidably connected to a connecting slider 6, the other side of each slide rod 5 is fixedly mounted on a fixed plate 1, and a Z-axis floating plate 2 is fixedly connected to the surface between the two connecting sliders 6. The motor assembly includes a motor base 8, a servo motor 7 is fixedly mounted on the surface of the motor base 8, a spinning shaft 20 is fixedly connected to the output end of the servo motor 7, and a pressing buckle cover 22 is fixedly mounted on the bottom end of the spinning shaft 20.

[0023] In use, since the slide bar 5 is fixedly installed on the fixed plate 1, the connecting slider 6 is slidably connected to the slide bar 5, the Z-direction floating plate 2 is fixed to the other side of the connecting slider 6, and the bottom end of the Z-direction floating plate 2 is fixedly connected to the rotating platform connecting plate 4. Therefore, when the Z-direction floating plate 2 descends, the rotating platform connecting plate 4 descends accordingly, and the hollow rotating platform 19 also descends. The descent of the hollow rotating platform 19 drives the partition 21 to descend, thereby driving the moving mechanism below the partition 21 to descend, thus aligning the tightening head with the clamping ring. During the upward process, since the limit spring 3 is fixedly installed at the top between the two slide bars 5, there is no need to worry about derailment. After the position between the two is adjusted, they need to be screwed and tightened. Start the servo motor 7 on the motor base 8, and the screwing shaft 20 at the output end of the servo motor 7 starts working, thereby driving the screw-lock cover 22 to rotate and tighten.

[0024] See Figures 3 to 5 Furthermore, the moving mechanism includes an X-axis fine-tuning component, the bottom of which is fixedly connected to a Y-axis fine-tuning component. The X-axis fine-tuning component includes an X-axis reset plate 11, with X-axis grooves on both sides of the top of the X-axis reset plate 11 and second seat grooves on both sides of the bottom of the X-axis reset plate 11. A first moving slider 10 is fixedly connected to one side of each of the two X-axis grooves, and a first moving seat 9 is slidably connected to one side of each of the two first moving sliders 10. The tops of the two first moving seats 9 are respectively fixedly connected to the interiors of the two first seat grooves. The Y-axis fine-tuning component includes a Y-axis reset plate 14, with Y-axis grooves on both sides of the top of the Y-axis reset plate 14, and a second moving slider 10 is fixedly connected to one side of each of the two Y-axis grooves. 3. A second movable seat 12 is slidably connected to one side of each of the two second movable sliders 13. The top ends of the two second movable seats 12 are fixedly connected to the interior of the two Y second seat slots respectively. The reset assembly includes four guide slots. The four guide slots are all opened on the side of the X-direction reset plate 11. An X-direction guide shaft 15 is provided inside the interior of each of the two guide slots. An X-direction guide sleeve 16 is slidably connected to both ends of the two X-direction guide shafts 15. An X-direction reset spring 17 is fixedly connected between the two X-direction guide sleeves 16. A Y-direction guide shaft 18 is provided inside the other two guide slots. A Y-direction guide sleeve 23 is slidably connected to both ends of the two Y-direction guide shafts 18. A Y-direction reset spring 24 is fixedly connected between the two Y-direction guide sleeves 23.

[0025] During use, if a slight error occurs in the Y-direction between the inner ring surface of the clamping spacer and the contact surface of the tightening head, the second movable seat 12 is fixed in the second seat groove at the bottom of the X-direction reset plate 11, and the second movable slider 13 is fixed in the Y-direction groove on the Y-direction reset plate 14. Since the second movable seat 12 and the second movable slider 13 are slidably connected, the second movable slider 13 on the Y-direction reset plate 14 will move, thereby causing the reset assembly inside the Y-direction guide groove to be compressed. Because the Y-direction guide sleeve 23 is slidably connected to the Y-direction guide shaft 18... Since the Y-direction guide sleeve 23 moves along the Y-direction guide axis 18 until the offset disappears, the Y-direction guide sleeve 23 drives the Y-direction reset plate 14 to return to its initial state under the action of the Y-direction reset spring 24. Similarly, when the offset occurs in the X-direction, the first moving seat 9 and the first moving slider 10 on the X-direction reset plate 11 will move, thereby squeezing the X-direction reset spring 17 inside the X-direction guide groove until the offset in the X-direction disappears. The X-direction guide sleeve 16 drives the X-direction reset plate 11 to return to its initial state under the action of the X-direction reset spring 17.

[0026] In this embodiment, the following steps are taken: First, the clamping spacer is installed into the water meter head. Then, the water meter head is aligned and the clamping head is tightened. Since the slide rod 5 is fixedly installed on the fixed plate 1, the connecting slider 6 and the slide rod 5 are slidably connected. The Z-direction floating plate 2 is fixed to the other side of the connecting slider 6. The bottom end of the Z-direction floating plate 2 is fixedly connected to the rotating platform connecting plate 4. Therefore, when the Z-direction floating plate 2 descends, the rotating platform connecting plate 4 descends accordingly, and the hollow rotating platform 19 also descends. The descent of the hollow rotating platform 19 causes the partition plate 21 to descend, thereby causing the moving part below the partition plate 21 to descend. The moving mechanism descends, aligning the tightening head with the clamping spacer. During the upward movement, since the limit spring 3 is fixedly installed at the top between the two slide rods 5, there is no need to worry about derailment. After the position is adjusted, they need to be screwed tight. The servo motor 7 on the motor base 8 is started, and the screwing shaft 20 at the output end of the servo motor 7 begins to work, driving the screw-on cover 22 to rotate and tighten. During this process, minor errors may occur, requiring fine-tuning. A slight error may occur in the contact surface between the inner ring of the clamping spacer and the tightening head in the Y direction. When there is an error, since the second movable seat 12 is fixed in the second seat groove at the bottom of the X-axis reset plate 11, and the second movable slider 13 is fixed in the Y-axis groove on the Y-axis reset plate 14, and the second movable seat 12 and the second movable slider 13 are slidably connected, the second movable slider 13 on the Y-axis reset plate 14 will move, thereby causing the reset component inside the Y-axis guide groove to be squeezed. Since the Y-axis guide sleeve 23 is slidably connected to both ends of the Y-axis guide shaft 18, the Y-axis guide sleeve 23 will move along the Y-axis guide shaft 18 until the offset disappears. Under the action of the Y-direction reset spring 24, the guide sleeve 23 drives the Y-direction reset plate 14 to return to its initial state. Similarly, when the X-direction is offset, the first moving seat 9 and the first moving slider 10 on the X-direction reset plate 11 will move, thereby squeezing the X-direction reset spring 17 inside the X-direction guide groove until the X-direction offset disappears. Under the action of the X-direction reset spring 17, the X-direction guide sleeve 16 drives the X-direction reset plate 11 to return to its initial state. Therefore, the moving mechanism can perform adaptive centering during the spinning and tightening process, which helps to reduce the workload of manual adjustment.

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.
