Description

Technical Field

[0001] This utility model relates to the technical field of steering column assembly tools, specifically an assembly tooling structure for assembling a steering column assembly. Background Technology

[0002] The steering column assembly is a core component of the vehicle's steering system, mainly consisting of the steering column and the lower control plate. Its assembly precision directly affects steering handling and safety. During assembly, the steering column must be inserted vertically into the mounting hole of the lower control plate. Power transmission is achieved through the rigid connection between the two. When the steering column rotates, it drives the lower control plate to rotate synchronously, thereby completing the vehicle's steering action.

[0003] During assembly, the vertical positioning of the steering column relies on manual support or simple brackets, which has significant drawbacks: the steering column is relatively long, and manual support alone is prone to top and bottom displacement due to hand tremors and uneven force application, resulting in tilting; simple brackets are mostly fixed structures, which cannot simultaneously limit the top and bottom of the steering column, and are difficult to adapt to steering columns of different lengths, resulting in poor adjustment flexibility.

[0004] This directly leads to two major problems: First, the perpendicularity of the steering column and the lower connecting plate needs to be repeatedly calibrated during assembly, which prolongs the operation time and reduces assembly efficiency; second, it is easy to cause the axis of the steering column and the lower connecting plate to deviate after assembly, which may cause hidden dangers such as steering jamming and poor return to center, affecting driving safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5This utility model proposes an assembly tooling structure for assembling a steering column assembly, including a processing table 1, an assembly table 2 at the upper end of the processing table 1, two push components 3 symmetrically arranged at the front and rear of the upper end of the assembly table 2, and a detachable clamping block 4 at the output end of the push component 3, with a clamping groove on the inner side of the clamping block 4. Two support frames 6 are symmetrically arranged on the left and right sides above the assembly table 2. The support frame 6 is provided with a guide groove 7. The outer side of the guide groove 7 is provided with a first empty groove 14. A bottom rod 8 and a top rod 9 are provided between the two support frames 6. The bottom rod 8 is fixed to the bottom of the support frame 6, and the top rod 9 is located at the top of the support frame 6. The two ends of the top rod 9 are provided with guide blocks 10 that are inserted into the guide groove 7 and slidably connected to the support frame 6. The outer side of the guide block 10 is provided with a rectangular block 11 that passes through the first empty groove 14 and is slidably connected to the first empty groove 14. The outer side of the rectangular block 11 is provided with a locking rod 12. The outer end of the locking rod 12 is fixed with a locking knob 13. The locking rod 12 is inserted into the rectangular block 11 and threadedly connected to the rectangular block 11. The middle part of the bottom rod 8 and the top rod 9 are provided with a ring frame 24. The inner ring of the ring frame 24 is provided with a detachable ring sleeve 25. The ring sleeve 25 is provided with a positioning hole. The processing table 1 is also equipped with a drive assembly for lifting and lowering the drive support frame 6.

[0018] The guide groove 7 has a T-shaped cross-section, and the first empty groove 14 and the second empty groove 16 both have rectangular cross-sections.

[0019] Adaptation and adjustment preparation: The annular sleeve 25 passes through the annular frame 24 and is threadedly connected to the annular frame 24. Multiple actuating blocks are symmetrically arranged at the upper end of the annular sleeve 25. An annular plate is provided at the top of the annular sleeve 25, and the annular plate is located at the upper end of the annular frame 24.

[0020] Based on the length of the directional column to be assembled, turn the locking knob 13 counterclockwise to disengage it from the support frame 6. The guide block 10 and the guide groove 7 slide together to push the top rod 9. After adjusting to the appropriate height, turn the locking knob 13 in the opposite direction to lock the top rod 9 in place.

[0021] If the steering column diameter is different, the annular sleeve 25 can be removed by rotating the toggle block and replaced with an annular sleeve 25 with the corresponding positioning hole size. The annular sleeve 25 is fixed by the threaded connection between the annular sleeve 25 and the annular frame 24 to ensure that the positioning hole is compatible with the steering column.

[0022] Vertical positioning of steering column: The steering column is vertically inserted through two annular sleeves 25 on the bottom rod 8 and the top rod 9. The positioning hole fits tightly with the outer wall of the steering column. The double upper and lower limit prevents the steering column from shaking or tilting, and accurately maintains a vertical state.

[0023] Lower connecting plate fixed limit: The output end of the propulsion component 3 is provided with a drive rod 5, and one end of the drive rod 5 is provided with a positioning plate. The positioning plate is fixed to the outside of the clamping block 4 by screws.

[0024] Place the lower connecting plate on the upper end of assembly table 2 and adjust its position so that the mounting holes of the lower connecting plate are precisely aligned with the lower end of the steering column.

[0025] Start the propulsion component 3, and push the clamping block 4 towards the center through the drive rod 5. The clamping groove and the contour of the lower connecting plate are adapted to achieve tight clamping, so as to avoid displacement of the lower connecting plate during the assembly process.

[0026] Assembly operation execution: With a gentle tap on the upper end of the steering column, and thanks to the dual protection of vertical positioning and lower connecting plate fixation, the lower end of the steering column smoothly inserts into the mounting hole of the lower connecting plate, completing the rigid connection between the two.

[0027] Unloading and resetting operation: The drive assembly includes a motor 19 and a rotating shaft 20. Two second slots 16 are symmetrically arranged on the processing table 1. A base frame 17 is slidably arranged at the second slots 16. The lower end of the base frame 17 is provided with a bottom block 18 that passes through the second slots 16. The upper end of the base frame 17 is provided with a support rod 15 that connects to the bottom of the support frame 6. The two ends of the support rod 15 are respectively hinged to the base frame 17 and the support frame 6. The motor 19 is fixed on one side of the processing table 1. The rotating shaft 20 is located below the processing table 1. The output end of the motor 19 is connected to one end of the rotating shaft 20. Two threaded rods 21 with reverse threads are symmetrically arranged on the rotating shaft 20. The two threaded rods 21 pass through the two bottom blocks 18 respectively and are threadedly connected to the bottom blocks 18. The lower end of the processing table 1 is provided with a limiting plate, and the end of the rotating shaft 20 away from the motor 19 is rotatably connected to the limiting plate through a bearing.

[0028] Two support rods 22 are symmetrically arranged on both sides of the assembly table 2. The lower end of the support frame 6 is provided with a vertical rod 23 inserted into the support rod 22. The vertical rod 23 is slidably connected to the support rod 22. The lower end of the support rod 22 is fixed to the upper end of the processing table 1.

[0029] After assembly, start motor 19 drives shaft 20 to rotate. The reverse threaded rod 21 on shaft 20 drives the two base blocks 18 to move closer to each other. The base frame 17 moves synchronously, causing the top of support rod 15 to lift support frame 6.

[0030] At this point, the vertical rod 23 slides out along the support rod 22, and the support frame 6 rises as a whole until the two annular sleeves 25 are completely disengaged from the steering column. Then, the assembled steering column assembly can be removed, and the motor 19 can be turned off to reset the device.

[0031] The propulsion component 3 drives the clamping block 4 to precisely clamp the lower connecting plate. The clamping groove matches the contour of the lower connecting plate, avoiding displacement deviation during assembly. The sliding cooperation between the support rod 22 and the vertical rod 23 further enhances the stability of the support frame 6 during lifting and lowering, ensuring structural stability throughout the assembly process.

[0032] The clamping block 4 is fixed by a positioning plate and screws, and the annular sleeve 25 is connected to the annular frame 24 by threads. Both can be quickly disassembled and replaced, which facilitates daily cleaning and replacement of worn parts, and extends the overall service life of the tooling.
