Abstract
The invention provides a manufacturing method of a novel connecting rod supporting structure for a high-speed loom, and relates to the technical field of machining. The method comprises the following steps that after raw materials of a retainer are mixed, a mixed raw material is obtained, the mixed raw material is molten into a liquid state in a staged heating manner, a runway type mold is adopted, injection molding is carried out, and demolding is carried out after cooling and curing; a steel ring is mounted in a retainer mounting hole by adopting an inlaying process; a bearing plate and a bottom plate are welded to form a base; a stainless steel round bar is cut and discharged through a cutting machine; and a shaft rod connected with a bearing and the retainer is installed in the bearing plate, and the supporting structure is obtained. The bearing plate and the bottom plate are welded to form the base, the bearing is firstly pressed on the shaft rod through a press machine, then the retainer is pressed on the outer side of the bearing, the shaft rod connected with the bearing and the retainer is installed in the bearing plate, the supporting structure is obtained, the retainer has good compression resistance and wear resistance and is not prone to cracking and high in toughness, and the method is particularly suitable for supporting of a connecting rod component in the high-speed loom.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a manufacturing method of a novel connecting rod support structure for a high-speed loom. Background technique [0002] The existing connecting rod group is generally composed of connecting rod body, connecting rod head cover, connecting rod small end bushing, connecting rod big end bearing bush and connecting rod bolt (or screw), etc. The connecting rod group bears its own swing and the reciprocating inertia of the connecting parts The magnitude and direction of these forces change periodically. Therefore, the connecting rod is subjected to alternating loads such as compression and tension. The connecting rod must have sufficient fatigue strength and structural rigidity. Insufficient fatigue strength often causes The connecting rod body or connecting rod bolts are broken, which will lead to major accidents of complete machine damage. If the rigidity is insufficient...
