[0002] The automobile steering column is an important component of the automobile steering system. It connects the steering wheel and the steering gear, and is responsible for transmitting the steering force and steering intention applied by the driver on the steering wheel to the steering gear, thereby controlling the steering of the wheels. The structure, performance and reliability of the steering column directly affect the vehicle's handling stability, driving comfort and safety.

[0003] The automobile steering column assembly welding fixture is a tooling equipment specially used for automobile steering column welding processing. It is designed to ensure that the steering column and its accessories maintain a precise relative position during the welding process, thereby ensuring the welding quality and the performance of the final product.

[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 ,in, Figure 1 This is a schematic diagram of the overall structure of the automobile steering column assembly welding fixture provided by the utility model; Figure 2 Another perspective structural diagram of the automobile steering column assembly welding fixture provided by the utility model Figure 1 ; Figure 3 Another perspective structural diagram of the automobile steering column assembly welding fixture provided by the utility model Figure 2 ; Figure 4 for Figure 1 The state structure diagram shown; Figure 5 for Figure 2 The state structure diagram shown

[0026] In the specific implementation process, Figures 1 to 5 As shown, the automobile steering column assembly welding fixture comprises a bottom plate 1, the four corners of the bottom of the bottom plate 1 are respectively fixedly connected with bottom feet 6, and two handles 7 are respectively fixedly connected and provided on both sides of the bottom plate 1, so that there is enough space at the bottom of the bottom plate 1, so as to facilitate the installation of the fixing component, and the bottom plate 1 is fixedly connected with a fixing component for fixing the outer wall of the steering column;

[0027] Telescopic member 1, which is placed on the fixed assembly and is used to drive the fixed assembly to move closer to or farther from the steering column in a horizontal direction;

[0028] The telescopic member 2 is placed on the fixed assembly and is used to drive the fixed assembly to move closer to or farther from the steering column in a vertical direction;

[0029] It should be understood from the above scheme that, first, the staff places the steering column to be welded on the fixed assembly, and operates the telescopic member 1 to drive the fixed assembly to approach the steering column in the horizontal direction. The telescopic member 1 should have sufficient thrust and precise stroke control to ensure that the fixed assembly can fit closely to the outer wall of the steering column to achieve effective fixation in the horizontal direction. At the same time, the telescopic member 2 is operated to drive the fixed assembly to approach the steering column in the vertical direction. The telescopic member 2 should also have sufficient thrust and precise stroke control to cooperate with the telescopic member 1 to ensure the precise positioning of the steering column in three-dimensional space.

[0030] In this way, by adopting the above arrangement, during the mass production process, the linkage design of telescopic part one and telescopic part two is adopted, which can quickly and accurately realize the fixing and releasing of the steering column, greatly shortening the clamping time of a single steering column and improving production efficiency; on the other hand, it ensures the consistency of each steering column in the fixed state, which is conducive to improving the consistency of welding quality.

[0031] like Figures 1 to 5 As shown, the fixing assembly includes an upper seat 2, a lock hole detection seat 5, a middle bracket detection seat 3 and a lower bracket detection seat 4 which are sequentially arranged on the bottom plate 1 along the conveying direction of the steering column, and the upper seat 2, the lock hole detection seat 5, the middle bracket detection seat 3 and the lower bracket detection seat 4 are all installed on the top of the bottom plate 1 by screw connection, the top of the middle bracket detection seat 3 is tilted toward the outer wall of the steering column, and the middle bracket detection seat 3 is slidably penetrated by a latch 8 along its tilt angle, and the outer wall of the latch 8 is fixedly connected to a sliding rod 17, the top of the lower bracket detection seat 4 is slidably penetrated by a latch 2 9 along the vertical direction, and the telescopic member 2 includes a cylinder 2 14, and the cylinder 2 14 is fixedly connected On the outer wall of the lower bracket detection seat 4, the output end of the cylinder 2 14 is fixedly connected with a connecting frame 2 15, one side of the connecting frame 2 15 is fixedly connected to the latch 2 9, a slide groove 16 is opened on the connecting frame 2 15, and a sliding rod 17 is placed in the slide groove 16 and can slide along its inner wall, a latch 3 10 is slid through the lower bracket detection seat 4 in the horizontal direction, and a latch 4 11 is slid through the lock hole detection seat 5 in the horizontal direction, and the telescopic member 1 includes a cylinder 12, and the cylinder 12 is fixedly connected to the outer wall of the pre-lock hole detection seat 5, and the output end of the cylinder 12 is fixedly connected with a connecting frame 13, and the side walls of the connecting frame 13 are respectively fixedly connected to the latch 3 10 and the latch 4 11.

[0032] It should be understood from the above scheme that when it is necessary to operate the telescopic member 1 to drive the fixed assembly to approach the steering column in the horizontal direction, by starting the cylinder 12, its output end begins to push the connecting frame 13 to move horizontally to one side, and the movement of the connecting frame 13 drives the latch 3 10 and the latch 4 11 fixed thereon to move synchronously, and the latch 3 10 moves into the lower bracket detection seat 4 to place the top position of the steering column, and the latch 4 11 moves into the lock hole detection seat 5 to place the bottom position of the steering column, and the two latches are respectively contacted with and inserted into the corresponding parts of the steering column, so as to realize the effective limit of the steering column in the vertical direction.

[0033] When it is necessary to operate the telescopic part 2 to drive the fixed assembly to approach the steering column in the vertical direction, by starting the cylinder 2 14, its output end begins to push the connecting frame 2 15 to move vertically downward. The downward movement of the connecting frame 2 15 directly drives the latch 2 9 to move downward. The latch 2 9 squeezes and fixes the top of the steering column to ensure its stability in the vertical direction. As the connecting frame 2 15 continues to move downward, the slide groove 16 inside it interacts with the sliding rod 17, and the sliding rod 17 slides on the inner wall of the slide groove 16 to ensure that the connecting frame 2 15 moves downward smoothly and accurately. The sliding of the sliding rod 17 drives the latch 1 8 to slide obliquely on the inner wall of the middle bracket detection seat 3. As the latch 1 8 slides, it gradually contacts and applies pressure on the outer wall of the steering column, and finally achieves the squeezing and fixation of the outer wall of the steering column to ensure its stable positioning in the horizontal direction.
