Abstract
The utility model discloses a steel ball seat structure. The steel ball seat structure comprises a spring seat and a cotter pin. The central portion of the spring seat is provided with a through hole which runs through in an upper-and-down manner. The cotter pin is inserted into the through hole. A cross beam is horizontally arranged at an opening in the top portion of the cotter pin. The central portion of the upper surface of the cross beam is provided with a welding arc-shaped surface. The steel ball seat structure of the utility model has the following advantages that by adding and arranging the cross beam having the arc-shaped surface between the opening of the cotter pin and a steel ball welding portion, so the wielding range is extended, the disadvantage that a point or a surface is taken as a narrow welding range in a conventional structure can be avoided, a steel ball can be welded easily, normal utilization can be ensured for a long time; the structure can be installed conveniently, and the stability between the steel ball and the cotter pin is improved.
Description
Technical field
The utility model relates to a kind of steel ball seat structure.
Background technique
Steel ball is widely used in the fields such as bearing, five metals, electronics, iron skill, machinery, electric power, mine, metallurgy, and its preparation process comprises punching press, tarry matter, quenching, hard grind, outward appearance, lappingout, cleaning, antirust, product packing.For example, for more existing machinery assemblies, when stationary balls, when the steel ball seat of bottom adopts steel ball and cotter pin weldering mode, generally need to make to put between cotter pin and steel ball contact weld, this makes when welding difficulty very big, and this mode of structure very easily comes off steel ball, this has affected the sealing after steel ball welding, even can reduction of service life.Therefore,, for above aspect, need to make rational improvement.
Model utility content
The purpose of this utility model is to provide a kind of steel ball and is easy to welding, easy to process, the steel ball seat structure that is conducive to improve welding efficiency, to solve many deficiencies of prior art.
The purpose of this utility model is carried out specific implementation by the following technical programs:
A structure, comprises spring seat and cotter pin, and described spring seat center position arranges a through hole running through up and down, and a cotter pin of the inner insertion of this through hole, is positioned at cotter pin top open part and is horizontally disposed with a crossbeam.
Described beam surface upper center position is provided with a welding cambered surface, and crossbeam two ends are separately fixed on cotter pin internal face, and described cotter pin is highly 30cm.
The beneficial effect of steel ball seat structure described in the utility model is: by setting up one with the crossbeam of cambered surface between the opening in cotter pin and steel ball welding part, expanded welding region, avoided conventional construction using a little or face etc. as comparatively narrow and small welding scope, make steel ball be easy to welding, can guarantee for a long time normal use; Structure is convenient to install, and also makes the stability between steel ball and cotter pin be improved.
Accompanying drawing explanation
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is the structural drawing of steel ball seat structure described in the utility model embodiment.
In figure: 1, spring seat; 2, cotter pin; 3, steel ball; 4, crossbeam; 5, welding cambered surface; 6, Vertical location hole.
Embodiment
As shown in Figure 1, steel ball seat structure described in the utility model embodiment, comprise spring seat 1 and cotter pin 2, described spring seat 1 center position arranges a through hole running through up and down, the cotter pin 2 of inner insertion of this through hole and this cotter pin 2 embed from the bottom to top gradually along spring seat 1 internal face, and the opening end that is positioned at cotter pin 2 arranges a steel ball 3;
Meanwhile, be positioned at cotter pin 2 top open parts and be horizontally disposed with a crossbeam 4 and crossbeam 4 upper surface center positions and be provided with a welding cambered surface 5, described crossbeam 4 two ends are separately fixed on cotter pin 2 internal faces, and described cotter pin 2 is highly 30cm.
In addition, described spring seat 1 two ends arrange respectively a Vertical location hole 6.
Claims (3)
1. a steel ball seat structure, comprises spring seat and cotter pin, it is characterized in that: described spring seat center position arranges a through hole running through up and down, and a cotter pin of the inner insertion of this through hole, is positioned at cotter pin top open part and is horizontally disposed with a crossbeam.
