[0039] During the vehicle assembly process, the tightening process of the steering gear, stabilizer bar and large nuts of the half-shaft causes the sliding column to rotate. There are three studs arranged at circumferential intervals on the sliding column. The rotation of the sliding column causes the studs to not align with the holes on the body, resulting in a low success rate of aligning the three studs on the sliding column with the holes on the body.
[0040] The utility model provides a correction component.
[0041] See also Figure 1 to Figure 2 In one embodiment of the utility model, the correction component 100 is used to correct the position of the sliding column, and the sliding column includes a positioning pin and a plurality of studs. The correction component 100 includes: a mounting frame 1, an adjustment component 2, a matching component 3 and a driving component 4; the adjustment component 2 is installed on the mounting frame 1 and has a mounting plate 21; the matching component 3 is movably installed on the mounting plate 21, and the matching component 3 has a first positioning hole 31 and a plurality of second positioning holes 32, the first positioning hole 31 is used for the positioning pin to pass through, and the plurality of second positioning holes 32 are used for the plurality of studs to pass through; the driving component 4 is installed on the mounting plate 21 and is drivingly connected to the matching component 3; wherein the adjustment component 2 is used to adjust the first positioning hole 31 to be aligned with the positioning pin, and the driving component 4 is used to drive the matching component 3 to move toward or away from the sliding column, and drive the matching component 3 to rotate so that the plurality of second positioning holes 32 correspond to the plurality of studs.
[0042] The technical solution of the utility model is to first make the matching piece 3 match with the sliding column, and then make the driving component 4 drive the matching piece 3 and drive the sliding column to rotate, so as to correct the position of the sliding column. The sliding column includes a positioning pin and a plurality of studs. The positioning pin is set at the center position, and the studs are arranged around the circumference of the positioning pin and are arranged at intervals. Generally, there are three studs. The number of the second positioning holes 32 in the correction component 100 can be kept corresponding to the number of the studs of the sliding column, and the specific number is not limited. For a certain vehicle model, after the material is received on the assembly line, the position of the sliding column can be fixed by some positioning devices. However, for different vehicle models, the position of the sliding column is different after positioning. In order to have a corrective effect on the sliding columns of different vehicle models, an adjustment component 2 is installed on the mounting frame 1 to adjust the initial position of the matching piece 3 so that when the matching piece 3 is in the initial position, the matching piece 3 corresponds to the sliding column (the first positioning hole 31 of the matching piece 3 corresponds to the positioning pin of the sliding column). Due to the previous assembly process, the sliding column may rotate, which may cause the stud on the sliding column to misalign with the second positioning hole 32 on the matching component 3. In order to adjust the circumferential position of the sliding column, the sliding column must first be matched with the matching component 3, and then adjusted by the driving component 4. Specifically: First, the driving component 4 is used to drive the matching component 3 to move in the direction toward the sliding column. If the stud passes through the second positioning hole 32, it means that the position of the sliding column is normal and does not need further correction. If the stud does not pass through the second positioning hole 32, it means that the position of the sliding column is abnormal and needs further correction. When the stud does not pass through the second positioning hole 32, the matching component 3 will abut against the sliding column. At this time, when the force toward the sliding column is continued to be applied to the matching component 3, the matching component 3 is rotated at the same time to make the second positioning hole 32 correspond to the stud. The stud passes through the second positioning hole 32, indicating that the matching is completed. At this time, the driving accessory is rotated back by the same angle to correct the position of the sliding column. Finally, the matching component 3 is driven to move away from the sliding column and return to the initial position to prepare for the next correction.
[0043] In order to move the mating piece 3 toward or away from the slide column, in one embodiment: the mounting plate 21 includes a slide rail 211; the driving assembly 4 includes a driving plate 41 and a driving electric cylinder 42; the driving plate 41 has a slide groove 411, the slide groove 411 is slidably connected to the slide rail 211, and the driving plate 41 is used for the movable installation of the mating piece 3; the driving electric cylinder 42 is drivingly connected to the driving plate 41. The mating piece 3 is movably mounted on the driving plate 41, and the driving electric cylinder 42 is drivingly connected to the driving plate 41. The driving electric cylinder 42 drives the driving plate 41 to move, which indirectly drives the mating piece 3 to move, so as to drive the mating piece 3 to move toward or away from the slide column. In order to ensure the connection relationship between the driving plate 41 and the mounting plate 21, so that it is not easy to separate, the accuracy of movement is also ensured, and the displacement in other directions during the movement is prevented, resulting in the second positioning hole 32 always unable to correspond to the stud.
[0044] In order to achieve the correspondence between the second positioning hole 32 and the stud, it is also necessary to enable the mating piece 3 to achieve rotational movement. Specifically, the mating piece 3 is rotatably installed on the driving plate 41, and the driving assembly 4 also includes a driving motor 43, which is fixedly installed on the driving plate 41 and is drivingly connected to the mating piece 3.
[0045] In order to determine whether the matching piece 3 is in place with the sliding column, the correction assembly 100 includes a sensor 5, which is fixedly arranged on the matching piece 3 and is arranged corresponding to the opening of the first positioning hole 31 opposite to the end of the positioning pin. When the stud enters the second positioning hole 32, the positioning pin can be detected by the sensor 5, and it can be determined whether the matching piece 3 is in place with the sliding column, so as to proceed to the next step.
[0046] In order to make the initial position of the fitting 3 adjustable and meet the needs of more models, the utility model is designed that the adjustment component 2 can be rotated and adjusted along the vertical axis.

Loosen the first bolt assembly 23 when adjustment is required, and tighten the first bolt assembly 23 after the adjustment is completed.
[0047] In order to make the initial position of the fitting 3 adjustable and meet the needs of more models, the utility model design that the adjustment component 2 can only be adjusted by rotation along the vertical axis is not enough to meet the needs. Further, the adjustment component 2 can also be adjusted by rotation along the left-right axis. Specifically: the first adjustment member 22 also has a plurality of second adjustment holes arranged along the left-right direction, and the plurality of second adjustment holes are arranged at intervals along the circumferential direction and extend along the circumferential direction; the adjustment component 2 also includes: a second adjustment member 24 and a plurality of second bolt assemblies 25; the second adjustment member 24 has a plurality of second through holes arranged along the left-right direction, and the plurality of second through holes are arranged at intervals along the circumferential direction; the plurality of second through holes are arranged correspondingly to the parts of the plurality of second adjustment holes; the plurality of second bolt assemblies 25 are respectively penetrated with a plurality of pairs of correspondingly arranged second adjustment holes and second through holes, so that the first adjustment member 22 and the second adjustment member 24 are fixedly connected. Loosen the second bolt assembly 25 when adjustment is required, and tighten the second bolt assembly 25 after the adjustment is completed.
[0048] In order to enable the fitting 3 to meet the adjustment of any angle to correspond to the sliding column, the adjustment assembly 2 can also be rotated and adjusted along the axis of the front-to-back direction. In one embodiment, specifically: the second adjustment member 24 has a plurality of third through holes arranged along the front-to-back direction, and the plurality of third through holes are arranged at intervals along the circumferential direction; the mounting plate 21 has a plurality of fourth through holes arranged along the front-to-back direction, and the plurality of fourth through holes are arranged at intervals along the circumferential direction; the number of the third through holes is greater than the number of the fourth through holes; the plurality of the fourth through holes are arranged correspondingly to the plurality of the third through holes; the adjustment assembly 2 also includes: a plurality of third bolt assemblies, which are respectively provided with a plurality of pairs of the third through holes and the fourth through holes arranged correspondingly, so that the second adjustment member 24 and the mounting plate 21 are fixedly connected.
