Description

Self-lubricating solid lubricating column structure

Technical Field

The utility model relates to a self-lubricating joint bearing production application particularly, relates to a self-lubricating solid lubrication post structure.

Background

At present, in the production and manufacturing process of a centripetal self-lubricating spherical plain bearing, solid lubricating columns are all cylindrical, in the embedding process, the solid lubricating columns are fixed by interference of the diameter of the solid lubricating columns and embedded cylindrical holes, in the embedding process, the solid lubricating columns are embedded into the embedding holes by a pickaxe striking method, compressed air can be generated at the bottoms of the embedding holes due to the interference, and in order to remove the compressed air, a method of placing for 12-24 hours after embedding and then striking each solid lubricating column again by a pickaxe is adopted. The method has the defect that compressed air cannot be completely discharged besides time and labor waste, and in the subsequent grinding process of the self-lubricating spherical bearing, the compressed air expands due to heat generated by grinding, so that the solid lubricating column is higher than the spherical surface and is ground, and after a bearing ring is processed and naturally cooled, the column shrinkage phenomenon is generated, (namely the end face of the solid lubricating column is lower than the spherical surface of the bearing), so that the lubrication of the bearing and the quality of a product are seriously influenced.

An effective solution to the problems in the related art has not been proposed yet.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to this phenomenon, design a circular mould ectosome and mould endosome, produce the solid lubrication post of regular polygon surface, at the inlaying in-process, because there are many gaps in the surface of regular polygon cylinder and the cylindrical pore surface of inlaying the hole, can make the downthehole air of inlaying discharge naturally, in later abrasive machining, owing to the effect that has not had the air of compressed, just can not produce the post phenomenon of contracting, need not wait for 12-24 hours and strike the solid lubrication post again yet, thereby the lubrication effect of bearing has been guaranteed.

In order to achieve the above object, the utility model provides a following technical scheme: a self-lubricating solid lubricating column structure comprises a mould outer body, a mould inner body and a regular polyhedron lubricating column, wherein the mould inner body is reserved in the mould outer body, the regular polyhedron lubricating column is arranged at the top of the mould outer body, and the bottom of the regular polyhedron lubricating column is communicated into the mould inner body.

Further, the outer body of the mould is a cylinder, and the inner body of the mould is a hollow cylinder.

Further, the regular polyhedron lubricating post is internally connected with the inner body of the clamping fixture.

Compared with the prior art, the utility model discloses following beneficial effect has: the regular polyhedron lubricating post is arranged and connected with the inner body of the mould in an internal connection mode, so that air in the embedding hole can be naturally discharged, the lubricating effect of the bearing is guaranteed, the manufacturing time of the product is saved, and the production period of the product is shortened.

fig. 2 is a top view of a self-lubricating solid lubricating column structure according to an embodiment of the present invention.

Reference numerals:

1. a mold outer body; 2. an inner body of the mould; 3. a regular polyhedron lubrication column.

Detailed Description

The following, with reference to the drawings and the detailed description, further description of the present invention is made:

referring to fig. 1-2, a self-lubricating solid lubricating pillar structure according to an embodiment of the present invention includes a mold outer body 1, a mold inner body 2, and a regular polyhedron lubricating pillar 3, the mold outer body 1 has the mold inner body 2, the regular polyhedron lubricating pillar 3 is disposed on the top of the mold outer body 1, and the bottom of the regular polyhedron lubricating pillar 3 is introduced into the mold inner body 2.

Through the above technical scheme of the utility model, mould ectosome 1 is the cylinder, mould endosome 2 is hollow cylinder, regular polyhedron lubrication post 3 internal connect in mould endosome 2 because regular polyhedron lubrication post 3 surfaces and the cylindrical hole mould endosome 2 surfaces of being inlayed the hole have many places gaps, be favorable to inlaying downthehole air and can discharge naturally.

In specific application, the outer surface of the regular polygon lubricating column 3 and the cylindrical hole surface of the inner body 2 of the die with the embedded hole are provided with a plurality of gaps, so that air in the embedded hole can be naturally discharged, in the subsequent grinding process, the column shrinkage phenomenon can not be generated due to the absence of the action of compressed air, the regular polygon lubricating column 3 does not need to be knocked again after 12-24 hours, and the lubricating effect of the bearing is ensured.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
