Abstract

The invention discloses a reinforcing welded steel ball seat, which comprises a spring seat and a cotter pin, wherein a vertical through hole is arranged at the center of the spring seat, and the cotter pin is inserted into the through hole; and an outwards oblique arc apex welding tape is arranged at the top of the cotter pin in a ring, and a welding lug boss is arranged on the inner wall surface of an opening of the cotter pin in a ring. The reinforcing welding steel ball seat provided by the invention has the beneficial effects that a plurality of welding components are additionally arranged between the cotter pin and a steel ball welding part to expand a welding area, and the situation that the traditional structure uses a point or surface and the like as a narrower welding range is avoided, so that a steel ball is easily welded, and the normal use can be ensured for a long time; and the structure is convenient to install, and the stability between the steel ball and the cotter pin is also improved.

Description

A kind of steel ball seat of reinforcing welding

Technical field

The present invention relates to a kind of steel ball seat of reinforcing welding.

Background technique

Steel ball is widely used in 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, need make generally that some contact welding between cotter pin and the steel ball, this makes that difficulty is very big when welding, and this mode of structure makes steel ball very easily come off, this has influenced the sealing after the steel ball welding, even can reduction of service life.Therefore, at above aspect, need make rational improvement.

Summary of the invention

The purpose of this invention is to provide that a kind of steel ball is easy to weld, the steel ball seat of easy to process, the reinforcing welding that is conducive to improve welding efficiency, to solve many deficiencies of prior art.

Purpose of the present invention is come specific implementation by the following technical programs:

A kind of steel ball seat of reinforcing welding comprises spring seat and cotter pin, and described spring seat center position arranges a through hole that runs through up and down, and cotter pin of the inner insertion of this through hole is positioned at the cotter pin top the outward-dipping arc overhead welding tape splicing of one circle is set.

Described arc overhead welding tape splicing internal face is arcuate structure, is positioned at a circle welding boss is set on the internal face of cotter pin opening.

The beneficial effect of the steel ball seat of reinforcing welding of the present invention is: by set up some weld assemblies between cotter pin and steel ball welding part, expanded welding region, avoided conventional construction with point or face etc. as comparatively narrow and small welding scope, make steel ball be easy to welding, can guarantee normal use for a long time; Structure is convenient to install, and the stability between steel ball and the cotter pin is improved.

Description of drawings

With embodiment the present invention is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the structural drawing of the steel ball seat of the described reinforcing welding of the embodiment of the invention.

Among the figure: 1, spring seat; 2, cotter pin; 3, steel ball; 4, arc overhead welding tape splicing; 5, welding boss.

Embodiment

As shown in Figure 1, the steel ball seat of the described reinforcing welding of the embodiment of the invention, comprisespring seat 1 andcotter pin 2, describedspring seat 1 center position arranges a through hole that runs through up and down, thecotter pin 2 of inner insertion of this through hole and thiscotter pin 2 embed from the bottom to top gradually alongspring seat 1 internal face, and the opening end that is positioned atcotter pin 2 arranges asteel ball 3;

Simultaneously, being positioned atcotter pin 2 tops, outward-dipping arc overhead welding tape splicing 4 and this arc overhead welding tape splicing 4 internal faces of one circle are set is arcuate structure, is positioned at a circle welding boss 5 to be set on the internal face ofcotter pin 2 openings and this welding boss 5 upper surfaces are arcuate structure.

Claims (3)

1. steel ball seat of reinforcing welding, comprise spring seat and cotter pin, it is characterized in that: described spring seat center position arranges a through hole that runs through up and down, and cotter pin of the inner insertion of this through hole is positioned at the cotter pin top the outward-dipping arc overhead welding tape splicing of one circle is set.

2. a kind of steel ball seat of reinforcing welding as claimed in claim 1, it is characterized in that: described arc overhead welding tape splicing internal face is arcuate structure.
