The centering assembly includes: an arc centering rod 21, the arc centering rod 21 is symmetric about the axial section where the positioning structure of the positioning sleeve 1 is located, and the inside of the arc centering rod 21 is a hollow sliding channel. A centering sphere 22 is slidably arranged in the sliding channel. An observation part 2101 is arranged at the center of the arc centering rod 21, and the centering sphere 22 can be exposed through the observation part 2101.

[0032] Specifically, the positioning auxiliary tool provided in this embodiment is used to assist in correcting the steering column 3 before installing the automobile steering wheel to achieve the correct installation of the steering wheel. The structure of the positioning auxiliary tool includes: a positioning sleeve 1 and a centering assembly. The positioning sleeve 1 is in a sleeve-like structure with openings at both ends, and its cross-sectional shape can be but is not limited to a circle. The positioning sleeve 1 can be sleeved on the outside of the end of the steering column 3 and is coaxial with the steering column 3. After installation, it can drive the steering column 3 to rotate synchronously, that is, the connection relationship between the positioning sleeve 1 and the steering column 3 can be but is not limited to one of the detachable connection methods such as clamping and connecting with a locking part. When installing the positioning sleeve 1, first align the positioning structure on the outer periphery of the positioning sleeve 1 with the positioning point 301 on the end face of the steering column 3 to achieve the alignment of the positioning sleeve 1 and the steering column 3; the centering assembly is installed on the positioning sleeve 1, and the centering assembly includes an arc centering rod 21. The arc centering rod 21 is a hollow arc rod-shaped structure with a circular cross-section. The inside of the arc centering rod 21 is a sliding channel for accommodating the centering sphere 22 and enabling the centering sphere 22 to freely slide to any position in the sliding channel. The center of the arc centering rod 21 corresponds to the position of the positioning structure on the positioning sleeve 1, and an observation part 2101 is arranged at the center. Since the arrangement position of the arc centering rod 21 is symmetric about the axial section where the positioning structure on the positioning sleeve 1 is located, after the positioning sleeve 1 and the steering column 3 are aligned, rotate the positioning auxiliary tool. The positioning sleeve 1 drives the steering column 3 to rotate synchronously. When the positioning auxiliary tool rotates to the centering sphere 22 just slides to the observation part 2101 under the action of gravity and is exposed through the observation part 2101, it means that the positioning auxiliary tool reaches the horizontal position and the steering column 3 is in the correct position, and the rapid alignment and positioning of the steering column 3 can be realized.

[0033] Among them, the arc centering rod 21 can be set as a rod structure that is hollow as a whole, or it can also be set that only the center of the arc centering rod 21 and part of the length on both sides of the center are hollow; the diameter of the centering sphere 22 can be adapted to the inner diameter of the sliding channel of the arc centering rod 21 to improve the accuracy of determining the horizontal position through the centering sphere 22; by improving the smoothness of the centering sphere 22 and the surface of the sliding channel, the free sliding of the centering sphere 22 in the sliding channel can be realized; the observation part 2101 is designed to be able to observe the centering sphere 22 when the centering sphere 22 reaches the center, and its setting form is not limited to through holes, through holes combined with transparent materials, etc.; the centering sphere 22 can be a steel ball, but is not limited thereto.

[0034] In addition, it should be noted that the positioning fixture provided in this embodiment can not only play a role in calibrating and positioning the steering column 3 before installing the steering wheel, but also can be used as a substitute for the steering wheel during the construction or repair of the vehicle. As a temporary steering operation fixture for the vehicle, it can avoid the damage to the clock spring parts caused by the repeated removal and installation of the steering wheel.

[0035] According to the above, the embodiment of the present invention provides a positioning fixture. The positioning sleeve 1 is sleeved on the steering column 3 to drive the steering column 3 to rotate synchronously, and the alignment structure of the positioning sleeve 1 is aligned with the alignment point 301 on the end surface of the steering column 3 to achieve the alignment of the positioning sleeve 1 and the steering column 3. Rotate the positioning fixture, and the positioning sleeve 1 drives the steering column 3 to rotate synchronously. When the centering sphere 22 just appears in the observation part 2101 when the positioning fixture rotates, it means that the positioning fixture reaches the horizontal position and the steering column 3 is in the correct position. It can realize the rapid alignment and positioning of the steering column 3, ensure the correct installation of the steering wheel, and the positioning fixture has a simple and light structure, convenient use steps, and improves the calibration efficiency of the steering column 3.

[0036] Further, referring to the attached Figure 1 - attached Figure 3 In a specific implementation, the centering assembly further includes: two centering handles 23, which are arranged outside the positioning sleeve 1 and are symmetrically arranged with respect to the axial section, and both ends of the arc centering rod 21 are respectively connected to the two centering handles 23.

[0037] Specifically, in order to facilitate the operation of the positioning fixture, in the technical solution adopted by the present invention, the positioning assembly further includes two centering handles 23 arranged on the positioning sleeve 1. The two centering handles 23 are symmetrically arranged with respect to the axial section where the alignment structure of the positioning sleeve 1 is located. The centering handle 23 can be specifically set as a rod, a plate, or in the shape of a bracket, etc., which can be used as the handheld part of the staff for easy operation, and as the force arm of the operation, it can reduce the steering force; both ends of the arc centering rod 21 are also respectively connected to the two centering handles 23, and the arc centering rod 21 is located on the side opposite to the alignment structure.

[0038] Further, in a specific implementation, the outer part of the centering sphere 22 has a coating, and the coating has a different color from the inner wall surface of the arc centering rod 21.

[0039] Specifically, for the convenience of the staff to observe the centering sphere 22, in the technical solution adopted by the present utility model, a coating can be provided on the outer part of the centering sphere 22. Taking the color of the inner wall surface of the arc centering rod 21 as gray as an example, the coating on the outer part of the centering sphere 22 can be set to red. In this way, when the centering sphere 22 has not reached the observation part 2101, what is seen from the observation part 2101 is the gray of the inner wall surface of the arc centering rod 21, and when the centering sphere 22 reaches the observation part 2101, what is seen from the observation part 2101 is the red of the centering sphere 22, which can form a distinct color difference and is convenient for the staff to observe.

[0040] Further, referring to Att Figure 1 -Att Figure 3 In a specific implementation, the observation part 2101 is a through hole opened in the arc centering rod 21 and communicating with the sliding channel, and the diameter of the through hole is smaller than the diameter of the centering sphere 22.

The through hole is located on the side of the arc centering rod 21 that is convenient for the staff to observe. The shape of the through hole can be, but is not limited to, circular, rectangular, etc., and the diameter of the through hole is smaller than the diameter of the centering sphere 22 to prevent the centering sphere 22 from sliding out from the position of the through hole.

[0042] Further, referring to Att Figure 1 -Att Figure 3 In a specific implementation, the alignment structure is an alignment groove 101 provided on the outer periphery of the positioning sleeve 1.

[0043] Specifically, for the convenience of aligning the alignment structure with the alignment point 301, in the technical solution adopted by the present utility model, the alignment structure can be set as an alignment groove 101 opened on the outer peripheral surface of the positioning sleeve 1. The bottom of the alignment groove 101 can be an arc surface, and the diameter can be adapted to or slightly larger than the alignment point 301 to facilitate the correspondence between the two. Optimally, the alignment groove 101 can be set as a groove body extending along the axial direction of the positioning sleeve 1 and at least penetrating one end face of the positioning sleeve 1. This end face is the end face facing the staff when the staff uses the positioning auxiliary tool, so that it is more convenient for the staff to align the alignment structure with the alignment point 301. Of course, the alignment structure can also be a protrusion provided on the end face or outer peripheral surface of the positioning sleeve 1, or a marking point added on the positioning sleeve 1, etc.

[0045] Specifically, in order to realize that the positioning sleeve 1 can be sleeved with the steering column 3 and can drive the steering column 3 to rotate synchronously, in the technical solution adopted by the utility model, a spline portion 102 can be circumferentially arranged on the inner cavity wall of the positioning sleeve 1, and the spline portion 102 is adapted to the tube head spline of the steering column 3. When the positioning sleeve 1 is sleeved on the outside of the steering column 3, the spline portion 102 of the inner cavity of the positioning sleeve 1 can engage with the tube head spline, so that when the positioning sleeve 1 rotates circumferentially, it can drive the steering column 3 to rotate synchronously, thereby realizing a convenient connection between the positioning sleeve 1 and the steering column 3 and convenient operation.

[0046] For further information, see Attachment Figure 1 In a specific implementation, the centering handle 23 includes a first rod body 231, a second rod body 232 and a third rod body 233 connected between the first rod body 231 and the second rod body 232, the extension directions of the first rod body 231 and the second rod body 232 are respectively in the same radial direction of the positioning sleeve 1, and the second rod body 232 and the first rod body 231 are staggered in the axial direction of the positioning sleeve 1; wherein, the two ends of the arc centering rod 21 are respectively connected to the corresponding second rod body 232.

[0047] Specifically, in order to avoid interference between the centering handle 23 and the side structure where the steering column 3 is located, in the technical solution adopted by the utility model, the centering handle 23 can be set as a rod-shaped structure, and can be set as a bent rod structure, specifically: the centering handle 23 includes a first rod body 231, a third rod body 233 and a second rod body 232 connected in sequence, wherein the extension direction of the first rod body 231 and the second rod body 232 is in the same direction as the radial direction of the positioning sleeve 1, and the first rod body 231 and the second rod body 232 are staggered in the axial direction of the positioning sleeve 1, and the third rod body 233 connected between the first rod body 231 and the second rod body 232 is connected to the first rod body 231 and the second rod body 232. The rod body 233 is an inclined rod body, so that the second rod body 232 and the third rod body 233 can form an avoidance space; the cross-sectional shape of the first rod body 231, the second rod body 232 and the third rod body 233 can be but not limited to a circle, and can be set as a hollow rod; the two ends of the arc centering rod 21 are respectively connected to the corresponding second rod body 232; optimally, the length of the first rod body 231 can be set to be smaller than the length of the second rod body 232, so as to increase the size of the avoidance space, and the plane where the centering handle 23 is located can be further set to be perpendicular to the axial cross section, which can further reduce the space occupied by the centering handle 23.
