Abstract
The invention discloses a steel ball sealing 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; a concave sealing seat is arranged below the cotter pin; and a sealing ring is arranged between the upper surface of the concave sealing seat and the spring seat. The steel ball sealing seat structure has the advantages that the independent sealing seat is arranged at the bottom of the cotter pin, and the sealing ring is arranged between the sealing seat and the spring seat, so that the integral sealing property is enhanced, and a steel ball is easy to weld and can 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
The present invention relates to a kind of steel ball seat, relate in particular to a kind of steel ball sealing stand structure.
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; Simultaneously, what need to pay attention to is, after spring seat inside is inserted in cotter pin, lacks the effective seal structure between the two, and this has influenced the sealing after the steel ball welding, reduction of service life sometimes.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, easy to process, the steel ball sealing stand structure of having strengthened the bottom sealing, 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 sealing stand structure, comprise spring seat and cotter pin, described spring seat center position arranges a through hole that runs through up and down, cotter pin of the inner insertion of this through hole, be positioned at the cotter pin below spill sealing seat is installed, between spill sealing seat upper surface and spring seat, be provided with seal ring.
Described spill sealing seat both sides are offered a positioning hole respectively.
Described spill sealing seat height is 12cm.
The beneficial effect of steel ball sealing stand structure of the present invention is: by in the cotter pin bottom independently sealing seat being set, and between sealing seat and spring seat, seal ring is set, strengthen overall tightness, also made 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 described steel ball sealing stand structure of the embodiment of the invention.
Among the figure: 1, spring seat; 2, cotter pin; 3, steel ball; 4, spill sealing seat; 5, seal ring; 6, positioning hole.
Embodiment
As shown in Figure 1, the described steel ball sealing stand structure of the embodiment of the invention, comprise spring seat 1 and cotter pin 2, described spring seat 1 center position arranges a through hole that runs 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;
Simultaneously, the segment distance of being separated by between a spill sealing seat 4 and this spill sealing seat 4 upper surfaces and spring seat 1 bottom surface is being installed below the cotter pin 2, between spill sealing seat 4 upper surfaces and spring seat 1, be provided with seal ring 5, described spill sealing seat 4 both sides are offered a positioning hole 6 respectively, and this described spill sealing seat 4 highly is 12cm.
In addition, described positioning hole 6 inner ends are through to the internal face of spill sealing seat 4.
