Abstract
The utility model discloses a kind of steering column pillar, comprise the pillar of tubular, the circle wall of described pillar is provided with for by coarctate for the bearing riveting of supporting installation in described pillar and described pillar U-shaped hole, the opening part in described U-shaped hole is provided with projection, the protrusion direction of described projection and the axis being parallel of described pillar that the bottom to described U-shaped hole is protruded.Steering column pillar of the present utility model, by adopting the riveting hole of U-shaped hole shape, effectively reduces the stress of distortion, can complete manufacture smoothly with existing installation, improve degree of utilization and the production efficiency of equipment when riveting.
Description
Technical field
The utility model relates to a kind of steering column pillar.
Background technology
In the structure of vehicular spare parts steering column, be ensure the rigidity of product and turning function, design is made up of pillar and steering shaft two parts usually, and what in this two parts engagement process, wherein play critical support and rotary action is bearing.Steering shaft stretches in bearing, bearing is located in pillar, the matching relationship of bearing and pillar and steering shaft is interference fit, namely bearing needs to be pressed in the middle of pillar by certain external force, and design goal be requirement its can not deviate from from pillar smoothly, in other words, what bearing was deviate from from pillar deviate from power must be greater than particular value.Based on this requirement, then need design a breach on pillar, for carrying out riveting to it after bearing is pressed into pillar, to reach above-mentioned particular requirement.
The design of existing riveting hole, encounters the phenomenon that riveting power is excessive in exemplar manufacturing process.Such as common yi word pattern punching hole, adopt riveting die extruding pillar wall during riveting, make it be out of shape, excess stock is pressed into, thus stops bearing to prolong axially to deviate from pillar inwall.But in actual manufacturing process, through repeatedly attempting, riveting position all fails to reach designing requirement.Its reason is that the shape in the hole of existing design and size cause deflection during riveting little, and deformational stress is large, and existing installation and frock can not meet the design shape requirement after riveting.Because the design of this pores relies on mould extruding to make it be out of shape completely, distortional stress is excessive, and riveting machine rated pressure can not reach requirement.
Summary of the invention
The technical matters that the utility model mainly solves is to provide a kind of steering column pillar, this steering column pillar is by adopting the riveting hole of U-shaped hole shape, effectively reduce the stress of distortion when riveting, manufacture can be completed smoothly with existing installation, improve degree of utilization and the production efficiency of equipment.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of steering column pillar, comprise the pillar of tubular, the circle wall of described pillar is provided with U-shaped hole, described U-shaped hole is used for described pillar together with the bearing riveting of installation supporting in described pillar, the opening part in described U-shaped hole is provided with projection, the protrusion direction of described projection and the axis being parallel of described pillar that the bottom to described U-shaped hole is protruded.
In the utility model preferred embodiment, described U-shaped hole is through hole.
In the utility model preferred embodiment, the described opening direction in U-shaped hole and the axes normal of pillar.
In the utility model preferred embodiment, described projection is trapezoid block, and the outer end width of described projection is less than the root width of described projection.
Described projection is cuboid block.
The beneficial effects of the utility model are: steering column pillar of the present utility model by adopting the riveting hole of U-shaped hole shape on pillar, the stress of distortion is effectively reduced when riveting, manufacture can be completed smoothly with existing installation, improve degree of utilization and the production efficiency of equipment.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of steering column pillar of the present utility model.
In accompanying drawing, the mark of each parts is as follows: 1, pillar, and 2, U-shaped hole, 3, projection.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of steering column pillar, comprise the pillar 1 of tubular, the circle wall of described pillar 1 is provided with for the coarctate U-shaped hole 2 of bearing riveting by supporting installation in described pillar 1 and described pillar 1, the opening part in described U-shaped hole 2 is provided with projection 3, the protrusion direction of described projection 3 and the axis being parallel of described pillar 1 that the bottom to described U-shaped hole 2 is protruded.
Preferably, described U-shaped hole 2 is through hole.
Preferably, the opening direction in described U-shaped hole 2 and the axes normal of pillar 1.
Preferably, described projection 3 is trapezoid block, and the outer end width of described projection 3 is less than the root width of described projection 3.
Preferably, described projection 3 is cuboid block.
Riveting hole on pillar is changed into U-shaped by yi word pattern, and have cuboid projection or ligulate projection, by the bearing in pillar 1 together with pillar 1 riveting in conjunction with time effectively reduce the stress that riveting is out of shape, the assembling of bearing and pillar 1 can be completed with existing common riveting press equipment smoothly, improve degree of utilization and the production efficiency of equipment.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
