Detailed Implementation

[0022] 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.

[0023] Example 1

[0024] like Figures 1-4 As shown, a calibration device for a torque sensor includes a worktable 1. From left to right, the upper end of the worktable 1 is provided with a first support groove 2, a positioning component, and a second support groove 3. Both the first support groove 2 and the second support groove 3 are upward-opening arc-shaped grooves 4. The first support groove 2 and the second support groove 3 are both fixed to the worktable 1. Lifting cylinders 5 are fixed to both sides of the worktable 1 on both sides of the first support groove 2, and a downward pressure rod 6 is fixed to the upper end of each lifting cylinder 5.

[0025] The positioning assembly includes a first positioning rod 7 and a second positioning rod 8 spaced apart. The lower end of the first positioning rod 7 is fixed to the worktable 1, and the upper end of the first positioning rod 7 is provided with a vertically elastic first positioning block 9. The lower end of the second positioning rod 8 is connected to a vertical cylinder 10, which is fixed to the worktable 1. The upper end of the second positioning rod 8 is provided with a vertically elastic second positioning block 11.

[0026] The lower ends of the first positioning block 9 and the second positioning block 11 are both fixed with vertical rods 12. The lower ends of the vertical rods 12 pass through the support springs 13 and slide inside the corresponding positioning rods, thereby realizing the vertical elastic extension and retraction of the first positioning block 9 and the second positioning block 11.

[0027] like Figure 5 and 6As shown, the torque sensor includes a rotating assembly 14 and a magnet assembly 15. Both the rotating assembly 14 and the magnet assembly 15 have positioning notches 17 on their shaft fixing sleeves 16. The two positioning notches 17 are axially aligned. The toothed ring of the rotating assembly 14 uses its positioning notch 17 as a positioning reference, and the magnetic poles of the magnet ring of the magnet assembly 15 are positioned using its positioning notch 17. The magnet assembly 15 is connected to the output shaft 18, and the rotating assembly 14 is connected to the input shaft 19. The first positioning block 9 engages with the positioning notch 17 of the magnet assembly 15, and the second positioning block 11 engages with the positioning notch 17 of the rotating assembly 14.

[0028] The method of using the calibration device is as follows: Place the shaft fixing sleeve 16 of the rotating component 14 and the magnet component 15 on the positioning component. The first positioning block 9 and the second positioning block 11 move down, and the corresponding support spring 13 is compressed. The output shaft 18 is placed in the first support groove 2, and the input shaft 19 is placed in the second support groove 3. Then rotate the torque sensor. When the positioning notch 17 rotates to the position of the corresponding positioning block, the support spring 13 extends, driving the corresponding positioning block to move up and place it in the positioning notch 17. Then connect the torque sensor to the duty cycle detector. The duty cycle detector is an existing device. If the duty cycle value is between 48% and 52%, it meets the requirements and no adjustment is needed. If the duty cycle is below 48% or above 52%, or if the center position is reversed, the state of the torque sensor needs to be adjusted. At this time, the lifting cylinder 5 extends and retracts, the pressing rod 6 moves down, and the output shaft 18 is fixed in the first support groove 2. Then the vertical cylinder 10 retracts, so that the second positioning block 11 moves away from the corresponding positioning notch 17, which facilitates the rotation of the rotating component 14, adjusts the relative position of the rotating component 14 and the magnet component 15, and adjusts the state of the torque sensor.

[0029] Alternatively, the first positioning block 9 can be engaged with the positioning notch 17 of the rotating component 14, and the second positioning block 11 can be engaged with the positioning notch 17 of the magnet component 15, so that the output shaft 18 is placed in the second support groove 3 and the input shaft 19 is placed in the first support groove 2. When the state needs to be adjusted, the state of the torque sensor can be adjusted by rotating the magnet component 15.

[0030] Example 2

[0031] This embodiment is basically the same as Embodiment 1, except that, as Figure 7 As shown, a horizontal guide rail 20 is fixed to the upper end of the worktable 1, and the lower end of the second positioning rod 8 is slidably disposed along the horizontal guide rail 20. A spacer block 21 is fixed to the right side of the first positioning rod 7, and the spacer block 21 limits the shortest distance between the first positioning rod 7 and the second positioning rod 8. This distance is consistent with the spacing between the two positioning notches 17. When it is necessary to adjust the state of the torque sensor, the second positioning rod 8 is moved to the right, so that the second positioning block 11 is away from its corresponding positioning notch 17, allowing the rotating assembly 14 to rotate.

[0032] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
