[0002] The steering column is a component connecting the steering wheel and the steering gear. Its main function is to transmit the driver's steering intention to the steering system for execution. When it is necessary to detect the steering column angle adjustment quality, that is, how much torque is required to achieve the required rotation angle when steering, if the torque is too large, it will be too difficult to turn. If the torque is too small, it is easy to cause the car turntable to float too much. The Chinese utility model patent, authorization announcement number "CN217654927U", discloses a quality inspection equipment for automobile steering column production, including a base, a fixing mechanism is provided on the surface of the base, a fixing seat is fixedly connected to the top surface of the base by bolts, a motor is fixedly connected to the inner wall of the fixing seat, and a torque sensor is rotatably connected to the output end of the motor, a connecting seat is fixedly connected to the surface of the torque sensor, and the connecting seat is fixedly connected to the base by bolts, and a connecting shaft is fixedly connected to the output end of the torque sensor.

[0003] The above technical solution drives the connecting shaft to rotate through the torque sensor, so that the fixing sleeve applies torque to the steering column. The torque sensor is used in conjunction with the overload device to detect the torque obtained by the steering column, thereby achieving the goal of facilitating the detection of the torque of the automobile steering column through the torque detection device, and avoiding the situation that most of the quality inspections for the production of traditional automobile steering columns are for testing the strength of the automobile steering column.

When clamping steering columns of different lengths, it can only rely on the clamp having a certain width to clamp steering columns of different lengths. Therefore, the clamping range is relatively limited. A detection device that can adjust the clamping range is required to expand the detectable steering column length range. Utility Model Content

[0026] See also Figure 1-4 , the utility model provides a technical solution: a steering column angle adjustment detection device, comprising a base 1;

[0027] The adjusting assembly is arranged on the base 1, and the adjusting assembly includes a baffle 5, a sliding groove 6, a sliding block 7, a threaded rod 16, a first gear 17 and a motor 18. The sliding groove 6 is arranged on the base 1, the sliding block 7 slides inside the sliding groove 6, the baffle 5 is welded on the sliding block 7, and the threaded rod 16 rotates on the base 1;

[0028] The positioning clamping assembly is arranged on the baffle 5, and the positioning clamping assembly includes a connecting column 8, a special threaded rod 9, a turntable 10, a handle 11, two connecting plates 12, two connecting rods 13, a frame 14 and two clamps 15. The connecting column 8 is welded to the baffle 5, and the frame 14 is symmetrically welded on the connecting column 8. Both connecting rods 13 slide through the frame 14, and the two clamps 15 are respectively welded to the corresponding connecting rods 13. Half of the threads of the special threaded rod 9 are clockwise and half of the threads are counterclockwise.

[0029] The inner surface of the sliding block 7 is threadedly connected to the surface of the threaded rod 16 , and the second gear 19 is sleeved on the threaded rod 16 .

[0030] The motor 18 is screwed onto the base 1 , the first gear 17 is keyed onto the output shaft of the motor 18 , and the teeth of the first gear 17 mesh with the teeth of the second gear 19 .

[0031] The two connecting plates 12 are respectively welded on the corresponding connecting rods 13, and the special threaded rod 9 rotates and penetrates the surface of the frame 14. The inner surfaces of the two connecting plates 12 are both threadedly connected with the surface of the special threaded rod 9.

[0032] A turntable 10 is welded to one side of the special threaded rod 9 , and a handle 11 is welded to the turntable 10 .

[0033] The upper surface of the base 1 is screwed with a driving motor 3 , the output shaft of the driving motor 3 is installed with a torque sensor 2 , the output axis of the torque sensor 2 is aligned with the axis of the connecting column 8 , and the output shaft of the torque sensor 2 is installed with a fixing sleeve 4 .

[0034] When it is necessary to detect the torque required for the angle change of steering columns of different lengths, first, one end of the steering column is installed on the fixing sleeve 4, and then the starting motor 18 drives the first gear 17 to rotate, the rotation of the first gear 17 drives the second gear 19 to rotate, the rotation of the second gear 19 drives the threaded rod 16 to rotate, the rotation of the threaded rod 16 drives the sliding block 7 to move, and the movement of the sliding block 7 drives the baffle 5 to move to a suitable position.

[0035] Secondly, rotating the handle 11 drives the turntable 10 to rotate, the rotation of the turntable 10 drives the special threaded rod 9 to rotate, the rotation of the special threaded rod 9 drives the two connecting plates 12 to move relative to each other, the relative movement of the two connecting plates 12 drives the corresponding connecting rods 13 to move relative to each other, and the relative movement of the two connecting rods 13 drives the corresponding clamping plates 15 to move relative to each other to clamp the other end of the steering column.

[0036] Finally, the drive motor 3 is started to output different torques, and the steering column rotation angle is recorded.

[0037] By setting the baffle 5 in the adjustment assembly, the baffle 5 can move to adjust the positions of its two clamps 15, so as to clamp steering columns of different lengths. The baffle 5 can move to adjust the positions of the two clamps 15, thereby expanding the length range of the steering column that can be clamped by the two clamps 15, thereby expanding the application range of the detection device.

[0038] Since the position of the torque sensor 2 is relatively constant, when the torque sensor 2 outputs torque, it is hoped that the axis of the steering column is consistent with the output axis of the torque sensor 2. By setting a special threaded rod 9 in the positioning clamping assembly, the special threaded rod 9 can drive the two clamping plates 15 to move relative to each other by the same distance. At the same time, after clamping the steering column, the axis of the steering column is parallel to the axis of the connecting column 8. Therefore, the central axis of the steering column is aligned with the axis of the output shaft of the torque sensor 2, thereby achieving the effect of automatically positioning the steering column.

[0039] Working principle:

[0040] When it is necessary to detect the torque required for the angle change of steering columns of different lengths, first, one end of the steering column is installed on the fixed sleeve 4, and then the starting motor 18 drives the first gear 17 to rotate, the first gear 17 drives the second gear 19 to rotate, the second gear 19 drives the threaded rod 16 to rotate, the threaded rod 16 drives the sliding block 7 to move, and the movement of the sliding block 7 drives the baffle 5 to move.

[0041] Secondly, rotating the handle 11 drives the turntable 10 to rotate, the turntable 10 drives the special threaded rod 9 to rotate, the special threaded rod 9 drives the two connecting plates 12 to move relative to each other, the two connecting plates 12 respectively drive the corresponding connecting rods 13 to move relative to each other, and the two connecting rods 13 respectively drive the corresponding clamping plates 15 to move relative to each other.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
