Furthermore, the embodiments and features in the embodiments of this application can be combined with each other without conflict.

[0043] Please refer to Figures 1-7 This invention provides a tilt angle detection mechanism, a tilt angle calibration device, and a calibration method to solve the problem of how to quickly measure the tilt angle and perform calibration to correct concentricity.

[0044] Specifically, please refer to Figure 1 This is a perspective view of a tilt angle detection mechanism provided in an embodiment of the present invention. The present invention provides a tilt angle detection mechanism 10, including a housing 11, a tilt angle sensor 12 and a torque balance sensor 13 connected in sequence. By combining the torque balance sensor 13 and the tilt angle sensor 12, the tilt angle of the structure under test can be measured quickly and accurately, providing accurate measurement results for subsequent calibration.

[0045] Specifically, please see Figure 2The housing 11 contains a first controller (not shown), and a first connector 112 is fixedly connected to the bottom of the housing 11. The first connector 112 is a plate-like structure with a plane, and the plane of the plate-like structure is used to connect the tilt sensor 12. The tilt sensor 12 is electrically connected to the first controller. The tilt sensor 12 includes a first sidewall 121 and a second sidewall 122 disposed opposite to each other. The first sidewall 121 and the second sidewall 122 are parallel to each other. The first sidewall 121 is rotatably connected to the first connector 112, and the first sidewall 121 is parallel to the connecting plane of the first connector 112, thereby ensuring the tilt sensor 12's... For measurement accuracy, the second sidewall 122 is detachably connected to the second connector 123. In some embodiments, a connecting groove is provided on the second sidewall 122, and a connecting hole is provided at the corresponding connecting hole of the second connector 123. The second sidewall 122 and the second connector 123 are connected by the connector passing through the connecting hole and connecting the connecting groove. The second sidewall 122 and the second connector 123 can be disassembled by removing the connector. When the plane to be measured is small and smooth, the bottom surface of the tilt sensor 12 can be directly contacted to the plane to be measured by removing the second connector 123, thereby realizing the tilt measurement of the small plane structure.

[0046] Furthermore, the torque balance sensor 13 is electrically connected to the first controller, and the torque balance sensor 13 is movably connected to the second connector 123. The torque balance sensor 13 includes a first contact arm 131 and a second contact arm 132 that are mated together. The plane formed by the first contact arm 131 and the second contact arm 132 is parallel to the first sidewall 121. To further ensure the measurement accuracy of the tilt sensor 12, by setting the first contact arm 131 and the second contact arm 132 to be mated together, the angle between the first contact arm 131 and the second contact arm 132 can be adjusted according to different sizes of the structure to be measured, thereby improving the tilt accuracy. The applicable range of the angle detection structure is as follows: the angle between the first contact arm 131 and the second contact arm 132 is adjustable between 15 degrees and 180 degrees. If the angle between the first contact arm 131 and the second contact arm 132 is less than 15 degrees, the tilt detection mechanism will be unstable and affect the measurement results. If the angle between the first contact arm 131 and the second contact arm 132 is greater than 90 degrees, the tilt sensor 12 will directly contact the surface to be measured, and the measurement results will be inaccurate due to the influence of the surface structure of the surface to be measured. The first end of the first contact arm 131 is connected to the first sensing head 1311, and the first end of the second contact arm 132 is connected to the second sensing head 1321. By setting the tilt sensor 12 and the torque balance sensor 13 to be electrically connected to the first controller, when the first sensing head 1311 and the second sensing head 1321 are in contact with the structure to be measured, the first controller controls the tilt sensor 12 to measure the tilt angle of the structure to be measured, ensuring convenient and fast detection while improving detection accuracy.

[0047] As a further improvement of the present invention, a first gear 1312 is provided at the second end of the first contact arm 131, and a second gear 1322 is provided at the second end of the second contact arm 132. The first gear 1312 meshes with the second gear 1322. By providing the first gear 1312 at the second end of the first contact arm 131 and the second gear 1322 at the second end of the second contact arm 132, and having the first gear 1312 mesh with the second gear 1322, the first contact arm 131 and the second contact arm 132 are connected through the meshing of the first gear 1312 and the second gear 1322. When adjusting the angle between the first contact arm 131 and the second contact arm 132, it is possible to better fix the angle between the first contact arm 131 and the second contact arm 132 to a corresponding angle according to the size of the structure to be measured, avoiding relative slippage during measurement that affects measurement accuracy, and improving the reliability of the tilt angle detection mechanism 10.

[0048] As a further improvement to the present invention, please refer to Figure 3-4The first gear 1312 has a first rotating shaft 13121 at its center, and the second connecting member 123 has a first rotating groove 1231 corresponding to the first rotating shaft 13121. The first rotating shaft 13121 is rotatably connected to the first rotating groove 1231. The second gear 1322 has a second rotating shaft 13221 at its center, and the second connecting member 123 has a second rotating groove 1232 corresponding to the second rotating shaft 13221. The second rotating shaft 13221 is rotatably connected to the second rotating groove 1232. By setting a first rotating shaft 13121 at the center of the first gear 1312, and a first rotating groove 1231 corresponding to the first rotating shaft 13121 on the second connecting member 123, the first rotating shaft 13121 is rotatably connected to the first rotating groove 1231. This ensures that when the first contact arm 131 rotates relative to the second connecting member 123, the first rotating shaft 13121 rotates within the first rotating groove 1231, preventing the first contact arm 131 from colliding with the second connecting member 123 during rotation and causing damage, thus affecting the sensing effect of the torque balance sensor 13. This is achieved by setting the second gear 132... The second rotating shaft 13221 is provided at the center of the 2nd component, and the second connecting member 123 is provided with a second rotating groove 1232 corresponding to the second rotating shaft 13221. The second rotating shaft 13221 is rotatably connected to the second rotating groove 1232, which ensures that when the second contact arm 132 rotates relative to the second connecting member 123, the second rotating shaft 13221 rotates relative to the second rotating groove 1232. This avoids the second contact arm 132 from colliding with the second connecting member 123 during rotation, which would cause damage and affect the sensing effect of the torque balance sensor 13. In this way, the safety performance of the tilt angle detection mechanism 10 is improved and the service life is extended.

[0049] As a further improvement of the present invention, a rotating knob 13122 is fixedly connected to the first rotating shaft 13121. By fixing the rotating knob 13122 to the first rotating shaft 13121, the first contact arm 131 can be rotated by rotating the rotating knob 13122, thereby adjusting the meshing position of the first gear 1312 and the second gear 1322 and controlling the angle between the first contact arm 131 and the second contact arm 132. It should be noted that the rotating knob can be fixedly connected to either the first rotating shaft 13121 or the second rotating shaft 13221, as long as one of the first rotating shaft 13121 or the second rotating shaft 13221 is fixedly connected to the rotating knob 13122. The present invention does not impose any limitations on this.

[0050] As a further improvement of the present invention, the tilt angle detection mechanism 10 further includes a clamping part 14, which includes a connecting handle 141 and a connecting ring 142. The connecting ring 142 is fixedly connected to the upper end of the housing 11. The connecting ring 142 has a mounting groove 1421 around its periphery and a limiting groove 1422 horizontally arranged around its periphery. The end face of the limiting groove 1422 is parallel to the first side wall 121. By setting the connecting ring 142, the reliability of clamping can be ensured. By setting the limiting groove 1422 horizontally around the connecting ring 142 and the end face of the limiting groove 1422 being parallel to the first side wall 121, the measurement direction of the tilt angle detection mechanism 10 can be quickly determined by the parallelism between the end face of the limiting groove 1422 and the first side wall 121 during clamping, thus better positioning the tilt angle detection mechanism 10.

[0051] As a further improvement of the present invention, the first connecting member 112 is provided with a rotating hole 1121, and a rotating shaft 1211 is fixedly connected to the first side wall 121, the rotating shaft 1211 passing through the rotating hole 1121. By providing a rotating hole 1121 on the first connecting member 112 and a rotating shaft 1211 fixedly connected to the first side wall 121, the tilt sensor 12 can rotate relative to the first connecting member 112 through the rotating shaft 1211 passing through the rotating hole 1121. This ensures that after the first sensing head 1311 and the second sensing head 1321 contact the inclined surface, the tilt sensor 12 tilts relative to the first connecting member 112, without causing the first connecting member 112 to tilt along with it, thereby affecting the connection stability of the upper clamping part 14 of the housing 11 and the measurement effect of the tilt sensor 12. A rotating shaft 1211 is fixedly connected to the first sidewall 121. A rotating hole 1121 is provided on the first connector 112. The rotating shaft 1211 is rotatably connected to the rotating hole 1121, ensuring that when the tilt sensor 12 rotates relative to the first connector 112, the rotating shaft 121 rotates relative to the rotating hole 1121 within the rotating hole 1121, thus avoiding damage caused by the tilt sensor 12 colliding with the first connector 112 during rotation. Preferably, the connection position of the rotating shaft 1211 is at the center of the first sidewall 121, improving the measurement accuracy of the tilt sensor 12.

[0052] As a further improvement to the present invention, please refer to Figure 5The housing 11 contains a battery compartment 113, which has an opening 1131 communicating with the side wall of the housing 11. A sealing cover 1132 is detachably connected to the opening 1131. By providing a battery compartment 113 inside the housing 11, the tilt angle detection mechanism 10 can be powered by replacing the battery, avoiding the limitation of measurement position by wired power supply. The opening 1131 in the battery compartment 113 communicating with the side wall of the housing 11, with the sealing cover 1132 detachably connected to the opening 1131, allows for easy and quick battery replacement by removing the sealing cover 1132, thus providing better power supply to the tilt angle detection mechanism 10.

[0053] The present invention also provides a tilt angle calibration device, please refer to [link to relevant documentation]. Figure 6 The system includes the aforementioned tilt detection mechanism 10, receiver 20, central shaft 30, clamping plate 40, fixed base 50, movable base 70, and second controller 60. Receiver 20 is electrically connected to the second controller 60 and infrared-connected to the first controller. The movable base 70 is also electrically connected to the second controller 60. By wirelessly connecting receiver 20 to the first controller, the system wirelessly receives angle measurements from the tilt sensor 12. The second controller 60 controls the movable base 70 to rotate the clamping plate by a corresponding angle, achieving deflection angle calibration. This allows for rapid and accurate angle detection and calibration.

[0054] Specifically, the end of the central shaft 30 is provided with a mounting protrusion (not shown) corresponding to the mounting groove 1421. The mounting protrusion cooperates with the mounting groove 1421 to achieve a fixed connection of the clamping part 14, ensuring the connection stability between the central shaft 30 and the tilt detection mechanism 10. The end of the central shaft 30 is provided with a limiting protrusion (not shown) corresponding to the limiting groove 1422. The limiting protrusion cooperates with the limiting groove 1422 to achieve positioning of the tilt detection mechanism 10. Since the end face of the limiting groove 1422 is parallel to the first side wall 121, the measuring plane of the tilt detection mechanism 10 can be quickly identified. The clamping plate 40 is provided at the bottom of the central shaft 30. The upper end face of the clamping plate 40 abuts against the first sensing head 1311 and the second sensing head 1321. One end of the clamping plate 40 is rotatably connected to the fixed seat 50, and the other end of the clamping plate is rotatably connected to the movable seat 70. The movable seat 70 is electrically connected to the second controller 60. By setting the receiver 20 to wirelessly connect with the first controller, the angle measured by the tilt sensor 12 can be wirelessly received. The second controller 60 controls the movable seat 70 to drive the clamping plate 40 to rotate by the corresponding angle, thereby realizing the deflection angle calibration. This enables fast and accurate angle detection and calibration.

[0055] This invention also provides a tilt angle calibration method, please refer to [link / reference]. Figure 7 ,include:

[0056] Tilt sensor 12 acquires the tilt angle of the clamping plate in the direction to be measured at 40°.

[0057] The first controller sends the tilt angle to the receiver 20;

[0058] The receiver 20 receives the tilt angle and sends it to the second controller 60;

[0059] The second controller 60 controls the movable seat 70 to rotate according to the tilt angle;

[0060] The clamping plate 40 rotates with the movable seat 7 to adjust the tilt angle, thereby calibrating the tilt angle in the direction to be measured.

[0061] It should be noted that after the clamping plate 40 rotates with the movable seat 70 to the tilt angle, the tilt sensor 12 will again obtain the tilt angle of the clamping plate 40 in the direction to be measured as the first angle. If the tilt angle at this time, i.e., the first angle, is 0 degrees, then the tilt angle in the direction to be measured has been calibrated. If the tilt angle at this time, i.e., the first angle, is not 0 degrees, then the first angle is sent to the receiver 20. The receiver 20 receives the first angle and sends it to the second controller 60. The second controller 60 controls the movable seat 70 to rotate the first angle according to the first angle. The clamping plate 40 rotates with the movable seat 70 to the first angle, thereby performing a second calibration until the tilt angle is 0 degrees.

[0062] As a further improvement of the present invention, before the tilt sensor 12 acquires the tilt angle of the clamping plate 40 in the direction to be measured, the following is also included:

[0063] Move the tilt detection mechanism 10 according to the direction to be measured of the clamping plate 40 until the first sidewall 121 is parallel to the direction to be measured of the clamping plate;

[0064] The first sensing head 1311 and the second sensing head 1321 abut against the clamping plate 40, and the torque balance sensor 13 sends a first signal to the first controller;

[0065] The first controller receives the first signal and controls the tilt sensor 12 to measure.

[0066] It should be noted that moving the tilt detection mechanism 10 to the first side wall 121 parallel to the direction to be measured according to the direction to be measured of the clamping plate 40 can be done manually, or it can be done by clamping the tilt detection mechanism 10 to the central axis 30, and the central axis 30 moves the tilt detection mechanism 10 to the first side wall 121 parallel to the direction to be measured of the clamping plate 40.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above embodiments merely illustrate preferred implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention.
