Problems solved by technology

For example, for some existing mechanical equipment components, when fixing the steel ball, when the steel ball seat at the bottom adopts the welding method of the steel ball and the cotter pin, it is generally necessary to make point contact welding between the cotter pin and the steel ball, which makes the It is extremely difficult to weld, and this structure makes the steel ball easily fall off, which affects the sealing performance of the steel ball after welding, and even shortens the service life

Embodiment Construction

[0011] Such as figure 1 As shown, the steel ball seat structure according to the embodiment of the present invention includes a spring seat 1 and a cotter pin 2. A through hole penetrating up and down is provided at the center of the spring seat 1, and a cotter pin 2 is inserted into the through hole and the The cotter pin 2 is gradually embedded along the inner wall of the spring seat 1 from bottom to top, and a steel ball 3 is arranged at the opening end of the cotter pin 2;

[0012] At the same time, a crossbeam 4 is horizontally arranged at the top opening of the cotter pin 2 and a welding arc surface 5 is arranged at the center position of the upper surface of the crossbeam 4. The two ends of the crossbeam 4 are respectively fixed on the inner wall of the cotter pin 2, and the 2 The height is 30cm.

[0013] In addition, a vertical positioning hole 6 is respectively provided at both ends of the spring seat 1 .

Abstract

The invention discloses a steel ball seat structure, which comprises a spring seat and a cotter pin. The center of the spring seat is provided with a through hole penetrating through the spring seat vertically; the cotter pin is inserted into the through hole; the top opening of the cotter pin is horizontally provided with a crossbeam; and the center of the upper surface of the crossbeam is provided with a welded cambered surface. The invention has the advantages that the crossbeam provided with the cambered surface is additionally arranged between the opening of the cotter pin and the welded part of a steel ball, a welding area is expanded, a narrow welding range due to contact or surface contact in the traditional structure is avoided, and the steel ball is easy to weld and ensured to be normally used for a long time; and the structure is convenient to mount, and the stability between the steel ball and the cotter pin is improved.

Description

technical field [0001] The invention relates to a steel ball seat structure. Background technique [0002] Steel balls are widely used in bearings, hardware, electronics, iron art, mechanical equipment, electric power, mining, metallurgy and other fields. . For example, for some existing mechanical equipment components, when fixing the steel ball, when the steel ball seat at the bottom adopts the welding method of the steel ball and the cotter pin, it is generally necessary to make point contact welding between the cotter pin and the steel ball, which makes the It is extremely difficult to weld, and this structure makes the steel ball easily fall off, which affects the sealing performance of the steel ball after welding, and even shortens the service life. Therefore, for the above aspects, reasonable improvements need to be made. Contents of the invention [0003] The object of the present invention is to provide a steel ball seat structure which is easy to weld, easy t...
