Description

Technical Field

[0001] The utility model relates to the technical field of steering systems, in particular to a riveting tool for adjusting nuts of automobile steering gears. Background Art

[0002] The steering gear of an automobile is composed of gears, racks, housings, adjustment nuts, dust covers and outer ball heads. The shaft at the upper end of the gear is connected to the steering system and the steering wheel, and the outer ball head is indirectly connected to the wheel. The meshing movement of the gear and the rack converts the rotational motion of the gear into the linear motion of the rack. The clamping mechanism is composed of a clamp, a spring, an O-ring and an adjustment nut, which can keep the rack pressed against the gear.

[0003] After the clamping mechanism is installed in the housing, the adjusting nut is screwed into the housing. The adjusting nut applies pressure to the spring, causing the spring to deform and compress the clamp, which in turn compresses the rack. As the road conditions faced by cars are complex and diverse, the working environment of the steering gear is also very complex. Impact, vibration, hot and cold changes, years of use and mileage, etc., will all affect the anti-loosening performance of the adjusting nut. Destroying the threads of the adjusting nut and the housing is an effective way to prevent loosening.

[0004] like Figure 1 As shown in the figure, when adjusting the rivet point of the nut, the rivet point force is relatively large, and there are certain requirements for the rivet point force direction and the rivet point support surface. After the rivet point, it is necessary to ensure the loosening torque requirement of the adjustment nut and the small deformation of the pressure block hole, so special equipment and tooling are required to complete it.

[0005] However, different types of adjusting nuts have different diameters and materials. Different types of steering gears are equipped with different types of adjusting nuts, which have different anti-loosening requirements and riveting requirements. Therefore, rivet heads of different shapes are required to meet the riveting point requirements of different types of adjusting nuts.

[0006] Therefore, in order to efficiently and conveniently realize the riveting points of the adjustment nuts of different models of steering gears, the manufacturing cycle of special equipment is long and the cost is high, so a highly versatile riveting point tooling for the adjustment nuts of automobile steering gears is designed. Summary of the invention

[0007] The utility model overcomes the deficiencies of the prior art and provides a riveting point tooling for an adjusting nut of an automobile steering gear. By selecting different rivet heads and bases, riveting points for automobile steering gears of different models and adjusting nuts of different models can be achieved, thereby improving the versatility of the invention and reducing the cost.

[0008] To achieve the above purpose, a riveting point tooling for an adjusting nut of an automobile steering gear is designed, comprising a locking screw, a cover plate, a rivet head, and a base, and is characterized in that: a plurality of rivet heads are evenly embedded on the base; the cover plate is connected to the top of the base through a plurality of locking screws; the top of the rivet head is a cylindrical structure, the middle rod body of the rivet head is a cylindrical structure with one side being a flat surface and the other side being an arc surface, and the bottom of the rivet head is a triangular structure, a semicircular structure, or an arc structure.

[0009] The cover plate is a circular panel structure, and a plurality of threaded holes are evenly distributed on the cover plate.

[0010] The base is a cylindrical structure, a through hole is arranged in the middle of the base, a plurality of rivet head holes for connecting rivet heads are evenly arranged at the outer edge of the through hole, and a connecting boss is arranged at the bottom of the through hole.

[0011] The boss is a circular ring structure.

[0012] The structure of the rivet head hole matches the structure of the rivet head.

[0013] There are at least 6 rivet heads, the inner side surface of the middle part of the rivet head is a plane structure, and the outer edge surface of the middle part of the rivet head is an arc surface structure; the bottom of the rivet head is a sheet structure, and the head of the sheet structure is triangular, semicircular or arc-shaped.

[0014] Compared with the prior art, the utility model provides a riveting point tooling for an adjusting nut of an automobile steering gear. By selecting different rivet heads and bases, riveting points for automobile steering gears of different models and adjusting nuts of different models can be achieved, thereby improving the versatility of the invention and reducing the cost.

[0023] The utility model is further described below with reference to the accompanying drawings.

[0024] like Figures 2 to 7 As shown, a plurality of rivet heads 3 are evenly embedded on the base 4; the top of the base 4 is connected to the cover plate 2 by a plurality of locking screws 1; the top of the rivet head 3 is a cylindrical structure, the middle rod body of the rivet head 3 is a cylindrical structure with one side being a flat surface and the other side being an arc surface, and the bottom of the rivet head 3 is a triangular structure or a semicircular structure or an arc structure.

[0025] The cover plate 2 is a circular panel structure, and a plurality of threaded holes 2 - 1 are evenly distributed on the cover plate 2 .

[0026] The base 4 is a cylindrical structure, with a through hole 4-1 in the middle of the base 4, and a plurality of rivet head holes 4-2 for connecting the rivet heads 3 are evenly distributed on the outer edge of the through hole 4-1; a connecting boss 4-3 is located at the bottom of the through hole 4-1.

[0027] The boss 4 - 3 is a circular ring structure.

[0028] The structure of the rivet head hole 4 - 2 matches the structure of the rivet head 3 .

[0029] There are at least six rivet heads 3, the inner side surface of the middle part of the rivet head 3 is a plane structure, and the outer edge surface of the middle part of the rivet head 3 is an arc surface structure; the bottom of the rivet head 3 is a sheet structure, and the head of the sheet structure is triangular, semicircular or arc-shaped.

[0030] One side of the rod of the rivet head 3 is a plane, and the other side of the rod of the rivet head 3 is an arc surface, so that the rivet head 3 can only be installed in the base 4 in a single direction.

[0031] The six rivet head holes 4-2 on the base 4 are evenly distributed in the circumference, and one side of the rivet head holes 4-2 of the base 4 is a flat surface, and the other side is a curved surface, which is exactly matched with the rivet head 3. The rivet head holes 4-2 are arranged on a circle of a specified diameter, and after the rivet head 3 is installed, the rivet head 3 is exactly aligned with the thread of the adjusting nut.

[0033] The three bolt holes of the base 4 are evenly distributed around the circumference, and the cover plate 2 is mounted to the base 4 by three locking bolts 1, and can be quickly disassembled to facilitate the replacement of the rivet head 3. Due to the large riveting force, the bottom of the rivet head 3 is thin, and the bottoms of the six rivet heads 3 are sometimes bent or broken. This design allows for convenient replacement of damaged rivet heads.

[0034] The bottom of the base 4 is provided with a boss 4-3, the outer diameter of which is closely matched with the inner diameter of the top of the adjusting nut, so as to play a centering role.
