Powder shaft sleeve chuck

Abstract

The invention discloses a powder shaft sleeve chuck. The powder shaft sleeve chuck is characterized by comprising an elastic wire left half portion and an elastic wire right half portion which are folded to be in left-and-right symmetry; the upper segment of the elastic wire left half portion and the upper segment of the elastic wire right half portion are straight segments which are in abut joint, the middle segments are gradually bent outwards, the lower segments are gradually and inwards retracted, arches are formed at the connecting positions of the lower segments and the middle segments, the upper segment of the chuck is a threaded connection head connected with a handle threaded connector, the lower segment of the chuck is a cone body with the small upper and the large lower, the cone body is formed in a manner that the connecting position of the threaded connection head extends downwards, a left and right opening which penetrates left and right is formed in the cone body and divides the cone body into paws in front-and-back symmetry, vertical limiting grooves which are in left-and-right centering and are in front-and-back symmetry are formed in the opposite faces of the paws, the upper segments of the elastic wire left half portion and the elastic wire right half portion can be inserted into the position between two vertical limiting grooves in a matched manner, a casing pipe is arranged on the outer side of the cone body, and a cone face abutting against the outer face of the cone body is arranged at the lower end of the casing pipe. Detaching is free, direct contact by the hand is avoided, the shaft sleeve is not likely to make contact with impurities, and the chuck is portable and reliable.

Description

technical field [0001] The invention relates to a tool for picking up a powder metallurgy shaft sleeve, in particular to a chuck for a powder shaft sleeve. Background technique [0002] my country is a big industrial country. With the advancement of science and technology, my country's manufacturing industry is booming, the economy is becoming stronger and stronger, new technologies and materials are constantly emerging, and powder metallurgy materials are one of them. Powder metallurgy can make porous, semi-dense or full-dense parts, such as oil bearing sleeves, which are widely used in various industries without cutting. It has unique chemical composition and mechanical and physical properties. It is a traditional metal processing method. Among them, iron powder is widely used because of its low cost and strong practicability.

Problems solved by technology

[0003] During the production and installation of the existing metallurgical powder oil-containing bushing, because the pores are filled with lubricating oil, the surface before installation is also soaked with lubricating oil. If you take it directly by hand during operation, it is easy to be contaminated with debris and affect its performance. , because it is round and cannot be held with tweezers as an existing tool, it still needs to be solved technically
