Inner-drive multi-head installing device for powder shaft sleeve

Abstract

The invention discloses an inner-drive multi-head installing device for a powder shaft sleeve. The inner-drive multi-head installing device is characterized in that three or four vertical holes are distributed circumferentially in the lower end face of a hollow tube at equal intervals, upper sections of elastic wires are fixed inside the corresponding vertical holes, a core rod and a holding tube are arranged on a handle, the lower end of the holding tube is connected with a threaded connector through a screwed joint, a vertical through space is formed inside the holding tube and the hollow tube, the core rod penetrates into the through space from the lower portion, a downwards-concaved step is arranged at the upper end of the holding tube, the upper end of the core rod is connected with a pressing ring, the outer diameter of the part, falling into the concave, of the pressing ring is larger than that of the core rod, the pressing ring is connected with a button, a compression spring is connected between the pressing ring and a boss, pressing strips which extend in the radial direction are connected to the lower section of the core rod, the number of the pressing strips is equal to that of the elastic wires, and the pressing strips are distributed between the adjacent elastic wires in a one-to-one correspondence mode. The inner-drive multi-head installing device is convenient to hold by the hand, achieves more convenient pressing operation, and is more stable and smaller in shaking during release.

Description

technical field [0001] The invention relates to a tool for picking up powder metallurgy shaft sleeves, in particular to an internal drive multi-head powder shaft sleeve installation device. 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, it is not stable to hold and release with the existing tool tweezers, and the structure of the coat-driven release developed by the inventor before is not convenient for hand pressing operation, and it is easy to shake when pressing, which still needs to be improved
