[0003] According to the "a kind of automobile steering wheel shape size detection tool" of Chinese patent publication No. CN222617806U, the main groove and four symmetrical guide grooves are opened at the top of the detection table, two symmetrical sliding blocks are arranged inside the groove, a roller is slidably arranged at the top of the guide groove, the roller and the sliding block are connected by a connecting rod, two measuring clamps are symmetrically arranged on the top of the detection table, a first knob and a second knob are rotatably connected to the side wall of the detection table, a first right and left threaded rod is arranged on the side wall of the first knob, a second right and left threaded rod is arranged on the second rotating side wall, a torsional spring is arranged on the side wall of the second knob, when detecting, first rotate the second knob to drive the second right and left threaded rod to rotate and press the torsional spring, use the screw structure to push the two measuring clamps away from each other, place the steering wheel on the top of the detection table, rotate the first knob to drive the first right and left threaded rod to rotate, use the screw structure to push the two sliding blocks away from each other, use the connecting rod to push the four rollers to expand and abut to the inner wall of the steering wheel handle, center the steering wheel handle, loosen the second knob, the torsional spring rebounds to drive the second right and left threaded rod to reverse, drive the two measuring clamps to approach and abut to the outer wall of the steering wheel handle, judge the outer diameter size of the steering wheel handle by the scale line at the bottom of the measuring clamp, at this time, rotate the steering wheel handle to make its inner wall fit the four rollers, when the steering wheel handle rotates, the distance between the two measuring clamps remains unchanged, indicating that the steering wheel handle is a perfect circle, which facilitates the measurement of the steering wheel handle diameter and the detection of its shape.

[0004] The common automobile steering wheel skeleton has a connecting hole between the steering wheel and the steering column, which ensures the close connection of the steering wheel and the steering column in structure. The common connecting hole is located at the center position of the steering wheel skeleton, so the connecting hole can be connected when the detection tool is connected, and an adjustable auxiliary rod can be used to limit the position of other screw holes on the detection tool, so that the automobile steering wheel can rotate in a circle, thereby facilitating detection. However, the connecting hole of part of the steering wheel skeleton is located at the eccentric side, which causes the automobile steering wheel to be unable to rotate in a circle, affecting the shape and size detection of the automobile steering wheel.

[0005] Therefore, a tooling for detecting the shape and size of automotive steering wheels is proposed to solve the problem that the connecting holes of some steering wheel frames are located on one side of the center, which makes it impossible to accurately determine the position of the automotive steering wheel during inspection, resulting in a complicated inspection process.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figs. 1-3The illustrated fixture for inspecting the shape and size of a car steering wheel includes a fixed platform 1. A first motor is fixedly connected to the center of the bottom end of the fixed platform 1, which drives a rotating plate 2 to rotate. The output end of the first motor is fixedly connected to the rotating plate 2. A limit groove is formed on the upper end of the rotating plate 2. A second motor is fixedly connected to one side of the limit groove on the rotating plate 2. When the second motor starts, it drives a screw 3 to rotate, which causes a movable frame 4 to move on the rotating plate 2. This causes the center point of the rotating plate 2 to shift from the center point of the movable frame 4. At this time, the center point of the car steering wheel can be adjusted to correspond with the center point of the rotating plate 2, thus facilitating the rotation of the car steering wheel around the center point and facilitating the inspection of the shape and size of the car steering wheel. The output end of the second motor is fixedly connected to the screw 3, and a movable frame 4 is threaded onto the screw 3. A storage groove is formed on the upper end of the movable frame 4, and a connecting block is fixedly connected inside the storage groove. A steering shaft hole main rod 5 is threaded onto the upper end of the connecting block. The main shaft 5 is connected to the car steering wheel via the shaft hole, and the auxiliary rod 10 is connected to other holes of the car steering wheel frame to improve the stability of the steering wheel frame. The moving frame 4 has sliding grooves on both sides of the storage slot. The moving frame 4 is fixedly connected to a third motor on one side of the sliding groove. The third motor drives the bidirectional lead screw 6 to rotate, which allows the sliders 7 to move relative to each other and move away. At this time, the auxiliary block 9 can move to any position in the storage slot. The output end of the third motor is fixedly connected to the bidirectional lead screw 6. The two sides of the bidirectional lead screw 6 that are far apart from each other are threaded with sliders 7. The two opposing sliders 7 are fixedly connected to a connecting rod 8. The auxiliary block 9 is sleeved on the connecting rod 8. The upper end of the auxiliary block 9 is threadedly connected to the auxiliary rod 10. The upper side of the auxiliary block 9 is threadedly connected to a positioning rod 11. Rotating the positioning rod 11 causes the limiting block 12 to connect with the connecting rod 8. The positioning rod 11 is inserted into the limiting block 12. The upper end of the limiting block 12 is fixedly connected to a protrusion. The limiting block 12 contacts the connecting rod 8.

[0019] Among them, spacer rings 13 are evenly fixedly connected to the connecting rod 8, and recesses are evenly opened on one side of the limiting block 12. The spacer rings 13 correspond to the recesses. By setting the recesses and spacer rings 13, the contact surface between the limiting block 12 and the connecting rod 8 can be increased, thereby fixing the position of the auxiliary block 9 in the storage slot and improving the adaptability of the auxiliary support.

[0020] The auxiliary block 9 has a hidden groove at its upper end, and the protrusion corresponds to the hidden groove. By setting the hidden groove, the upper end of the positioning rod 11 can be made flush with the upper end of the auxiliary block 9, which facilitates the placement of the steering wheel frame.

[0021] The fixed platform 1 has support plates 14 fixedly connected to both sides. Electric push rods 15 are fixedly connected to the opposite side of the two support plates 14. A calibration plate 16 is fixedly connected to the output end of the electric push rod 15. By setting the calibration plate 16, the steering wheel frame can be temporarily limited to ensure that the center point of the steering wheel frame corresponds to the center point of the rotating plate 2, and ensure that the steering wheel frame can rotate in a circle when the rotating plate 2 rotates.

[0022] The steering shaft hole main rod 5 has a groove at its upper end and an adjusting rod 18 is rotatably connected in the groove. A pressure plate 17 is threaded onto the adjusting rod 18. The pressure plate 17 contacts the groove. Rotating the adjusting rod 18 can cause the pressure plate 17 to press down, thereby limiting the position of the steering wheel frame.

[0023] Working principle: The center hole of the steering wheel frame is aligned with the main rod 5 of the steering shaft hole. Based on the position of other holes in the steering wheel frame, the third motor drives the double-acting screw 6 to rotate, causing the slider 7 to move relative to it. Then, the auxiliary block 9 is installed in a suitable position and connects with the positioning rod 11, the limiting block 12, and the connecting rod 8. Thus, the steering shaft hole main rod 5 and the auxiliary rod 10 can limit the steering wheel frame. Then, the adjusting rod 18 is rotated so that the pressure plate 17 presses on the upper side of the steering wheel frame. The electric push rod 15 and the calibration plate 16 move relative to each other and limit the steering wheel frame. Further, the third motor and the double-acting screw 6 are reversed, and the sliders 7 are moved away from each other, thereby stabilizing the position of the car steering wheel. Then, based on the position from the center point to the edge of the steering wheel frame supplied by the front end, the second motor drives the screw 3 to rotate, so that the center point of the steering wheel frame corresponds to the center point of the rotating plate 2. At this time, the first motor drives the rotating plate 2 and the steering wheel frame to rotate, which can make the car steering wheel frame rotate in a circle. At this time, the shape and size of the car steering wheel can be easily detected.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
