DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following is a more detailed description of the specific embodiments of the present utility model by referring to the drawings through the description of the embodiments, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and facilitate its implementation.

[0021] As Figures 1 to 3-2 shown, the right-hand drive steering column and steering gear assembly auxiliary tool includes a mounting block 3. The mounting block 3 is arranged between the steering column 1 and the steering gear 2, and the mounting block 3 is provided with a limiting structure and a guiding structure.

[0022] The installation block 3 is reasonably structured, with a limiting and guiding function, facilitating identification and operation, enabling the spline axes of the steering column 1 and the steering gear 2 to be collinear, and realizing the assembly connection of the steering column 1 and the steering gear 2 in a right-hand drive vehicle model in an assembly environment with limited space, so as to improve the convenience of the spline connection between the steering column 1 and the steering gear 2 and achieve the purpose of high-efficiency and high-quality assembly. Among them, the installation block 3 is made of aluminum alloy, with a light texture and reasonable ergonomics.

[0023] As Figure 3-1 and Figure 3-2 shown, the limiting structure includes a limiting block 5. The limiting block 5 is provided at the bottom of the installation block 3. The steering gear 2 includes a spline shaft 6. A first limiting surface 8 is provided on the spline shaft 6. A second limiting surface 9 is provided inside the limiting block 5. The first limiting surface 8 contacts the second limiting surface 9. Through the contact of a pair of limiting surfaces on the limiting block 5 and the spline shaft 6, the spline shaft 6 and the installation block 3 are relatively stationary. At the same time, combined with the guiding function of the guiding block 4, it is ensured that the axes of the steering column 1, the installation block 3 and the steering gear 2 are collinear and relatively stationary. The steering column 1 includes an internal spline 7, thus realizing the assembly accuracy of the internal spline 7 and the spline shaft 6.

[0024] As Figure 3-1 and Figure 3-2 shown, the guiding structure includes a guiding block 4. The guiding block 4 is provided at the upper end of the installation block 3. An opening groove 11 is provided at the bottom end of the steering column 1. The guiding block 4 extends into the opening groove 11. A spline 10 is provided inside the installation block 3. The spline 10 cooperates with the spline shaft 6. By using the cooperation of the guiding block 4 and the opening groove 11, the existing structure of the opening groove 11 on the steering column 1 is fully utilized to achieve the effect of simplifying the assembly process. After the guiding block 4 is inserted into the opening groove 11, the installation block 3 and the steering column 1 will be relatively stationary. When the limiting surfaces of the installation block 3 and the steering gear 2 are in contact, the axes of the steering column 1 and the steering gear 2 are collinear and then the accurate installation position can be reached. By using the guiding block 4 and the limiting block 5, after the spline 10 and the spline shaft 6 are matched, it has an anti-rotation effect on the installation block 3, making the fit between the limiting surfaces better, the insertion process of the guiding block 4 smoother, enabling the steering column 1 and the steering gear 2 to be connected at one time, avoiding the quality impact on the spline end caused by repeated connection, reducing the burr defects of the spline due to difficult assembly docking, improving the production efficiency of the production line, and reducing the rework intensity.

[0025] As Figure 2 shown, a connection hole 14 is provided outside the bottom end of the steering column 1. The connection hole 14 penetrates the opening groove 11. After the steering column 1 and the steering gear 2 are accurately positioned by using the installation block 3, by installing bolts in the connection hole 14, the opening groove 11 is locked, so that the internal spline 7 of the steering column 1 and the spline shaft 6 of the steering gear 2 are closely matched.

[0026] As Figure 3-1 andFigure 3-2 As shown, an opening 12 is provided on the mounting block 3. The provision of the opening 12 realizes the function of mounting the mounting block 3 from the radial direction, enabling the mounting block 3 to be directly withdrawn from the radial direction without the need for complex axial alignment after the mounting block 3 completes the guiding and limiting function. After the direction pipe column 1 is pulled down, it can be connected to the steering gear 2 in place, which simplifies the usage process and reduces the assembly difficulty.

[0027] As Figure 2 shown, the guiding block 4 and the limiting block 5 are arranged oppositely with respect to the axis of the spline shaft 6. In the above structure, the guiding block 4 and the limiting block 5 are arranged oppositely, so that the functional action areas of the two do not block each other, and a better anti-rotation effect can be provided.

[0028] As Figure 3-1 and Figure 3-2 shown, an inclined angle 13 is provided at the end of the guiding block 4. The provision of the inclined angle 13 reduces the area of the end of the guiding block 4, reduces the difficulty of inserting the guiding block 4 into the opening groove 11, and facilitates the assembly process.

[0029] As Figure 3-1 and Figure 3-2 shown, the edge of the mounting block 3 is an arc structure. The edge of the mounting block 3 adopts an arc transition, which is convenient for identification and operation during installation.

[0030] During assembly, first rotate and adjust the limiting surface of the mounting block 3 to fit the limiting surface of the steering gear 2, adjust the angle of the direction pipe column 1 so that the guiding block 4 is inserted into the opening groove 11 of the direction pipe column 1, pull the direction pipe column 1 downward until it is spline-connected to the steering gear 2, move downward so that the limiting block 5 fits the bottom of the limiting surface of the steering gear 2, pull out the mounting block 3, and finally pull the direction pipe column 1 downward. The internal spline 7 of the direction pipe column 1 is connected to the spline shaft 6 of the steering gear 2 in place. Use an electric angle wrench to tighten the bolt and lock the opening groove 11 to make the connection between the direction pipe column 1 and the steering gear 2 firm, thus completing the assembly process of the direction pipe column 1 and the steering gear 2.

[0031] This right-hand drive direction pipe column and steering gear assembly auxiliary tool solves the problem that the connection between the direction pipe column 1 and the steering gear 2 of the existing right-hand drive vehicle models requires multiple adjustments to be installed in place due to insufficient operating space, ensures that the direction pipe column 1 and the steering gear 2 are connected in place, and meets requirements such as accuracy and stability; at the same time, it reduces burrs caused by difficult assembly docking of the splines, ensuring product quality; the structure is simple, the operation is convenient, it can be applied to multiple vehicle models, simplifies the assembly steps, has high assembly efficiency, reduces the labor intensity of workers, and ensures the assembly quality.

[0032] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model; or without improvement, the above concept and technical solution of the present utility model are directly applied to other occasions, they are all within the protection scope of the present utility model.
