[0002] The steering shaft is a crucial component in a vehicle's steering system, connecting the steering wheel and steering column, transmitting torque and speed from the steering wheel to the column. As key steering components, the upper and lower bearings are at risk of dislodging and require reinforcement with rivets or anti-slip rings. To save costs, rivets are often used to prevent bearing dislodgment, curb steering failure, and significantly extend the service life of the steering column. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a steering shaft riveting tool with adjustable compound angles, which avoids the need for manual adjustment for repeated angle positioning each time and improves tooling efficiency.

[0004] To achieve the above purpose, a steering shaft riveting tool with adjustable compound angle is designed, which includes an upper pressing plate of a press, a lower pressing plate of a press, a guide column, and a rivet knife assembly. The characteristics are as follows: an angle adjustment mechanism is provided on the lower pressing plate of the press, the top of the angle adjustment mechanism is connected to the product rotation mechanism, a rivet knife assembly is provided above the product rotation mechanism, and the bottom of the rivet knife assembly is connected to the upper pressing plate of the press; the upper pressing plate of the press and the lower pressing plate of the press are connected by a guide column.

[0005] The product rotation mechanism includes a base plate, a front support seat, a rotating seat, a handle, and a knob plunger. One side of the base plate is connected to the front support seat, and the other side of the base plate is connected to the rotating seat.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the traditional manual assembly tool consists of a V-shaped support block 3 and a rivet cutter 1. After placing the steering shaft 2 on the V-shaped support block 3, a spirit level is used to level the product by shimming. The steering shaft 2 is then manually aligned with the center of the rivet cutter 1. The axial angle is visually adjusted before riveting. After one riveting operation is completed, the steering shaft 2 is manually rotated 90° and riveted again. At the same time, each riveting operation requires repeated manual positioning, requiring approximately three minutes of manual focus for each operation. This results in additional labor costs, slowing production progress, and delaying the product development cycle.

[0023] like Figures 2 to 7 As shown, an angle adjustment mechanism 8 is provided on the lower pressing plate 9 of the press, the top of the angle adjustment mechanism 8 is connected to the product rotating mechanism 7, a rivet cutter assembly 6 is provided above the product rotating mechanism 7, and the bottom of the rivet cutter assembly 6 is connected to the upper pressing plate 5 of the press; the upper pressing plate 5 of the press and the lower pressing plate 9 of the press are connected by a guide column 4.

[0024] The product rotation mechanism 7 includes a base plate, a front support seat, a rotating seat, a handle, and a knob plunger. One side of the base plate 7-2 is connected to the front support seat 7-1, and the other side of the base plate 7-2 is connected to the rotating seat 7-3. A guide groove is provided in the center of the rotating seat 7-3, and a bearing groove is provided on the outer side of the guide groove. A bearing 7-6 is embedded in the bearing groove. The rear side of the bearing 7-6 is connected to one end of the rear end rotating clamping block 7-8, and the other end of the rear end rotating clamping block 7-8 is connected to the rotating handle 7-4. The end of the rotating handle 7-4 is connected to the knob plunger 7-5; the rear side of the rotating seat 7-3 is connected to the rotating seat bearing end cover 7-7.

[0025] The bottom plate 7-2 and the rotating seat 7-3 are rectangular panel structures, and the bottom of the rotating seat 7-3 is connected to the bottom plate 7-2 through a groove.

[0026] Bearing 7-6 is a deep groove ball bearing.

[0027] After placing product 10 (i.e., steering shaft 2) onto front support 7-1, swivel base 7-3 moves forward through the groove in base plate 7-2, allowing the rear spline of product 10 (i.e., steering shaft 2) to engage the guide groove of swivel base 7-3. Now manually pull knob plunger 7-5 to unlock it, which then rotates handle 7-4 and rear-end rotary clamp 7-8. When the knob plunger 7-5 reaches the designated hole, release knob plunger 7-5, completing the fixed-angle rotation and locking.

[0028] The angle adjustment mechanism 8 includes a bearing seat, a motor, a tilt table base, a tilt table, a worm gear, and a worm. The front and rear sides of the tilt table base 8-3 are respectively connected to the bearing seat 8-1. The front and rear bearing seats 8-1 are provided with a worm gear 8-6, and the end of the worm gear 8-6 is connected to the motor 8-2; the upper side of the worm gear 8-6 is engaged with one end of the worm gear 8-5, and the other end of the worm gear 8-5 is connected to the tilt table 8-4.

[0029] The front and rear sides of the top of the angled table base 8-3 are connected to the bottom of the angled table 8-4 by using undercut grooves.

[0030] The tilt table 8-4 is connected to the bottom plate 7-2 of the product rotating mechanism 7 by bolts.

[0031] A bearing is sleeved between the worm 8-6 and the bearing seat 8-1.

[0032] The guide posts 10 are located on the left and right sides of the angle adjustment mechanism.

[0033] Worm 8-6 is secured by bearing block 8-1 (C-BGHA6901ZZ-20), with its rear end rigidly connected to motor 8-2. The tilt table base 8-3 mates with the tilt table 8-4 in an arc-shaped arrangement. An undercut groove on the tilt table base 8-3 ensures only rotational freedom of movement for the tilt table 8-4, preventing it from slipping out. Worm gear 8-5 is securely fastened to the bottom of the tilt table 8-4 and meshes with worm 8-6. When adjustment is required, motor 8-2 rotates worm 8-6, driving worm gear 8-5 and the tilt table 8-4 to achieve axial tilting motion, achieving fine-tuning.

[0034] The beneficial effects of the present invention are as follows: the riveting tool can quickly achieve radial rotation and axial leveling, and the electric tilting table and the rotating tool cooperate with each other to accurately extrude the riveting points. It is low in cost, very convenient to use, has a low defective rate, and is not likely to scratch the steering shaft surface.
