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

Embodiment Construction

[0011] Examples of the present invention figure 1 , 2 As shown, the live core drives the two-end powder bushing picker with a pick-up part and a handle part. The pick-up part is equipped with a chuck and an elastic wire. The upper section 1 of the elastic yarn in the left half and the right half is a straight section close together, the middle section 2 of the left half and the right half gradually bends outward, and the lower section 3 of the left half and the right half gradually bends inward. Receive, the connection between the lower section and the middle section forms an arc arch, and the arc arch can be an arc-shaped vault at one end, or a straight section. The connection between the lower section and the middle section of this embodiment is connected by a transition section 4, and the transition section is in a vertical state. It can be in better contact with the inner wall of the shaft sleeve, and the connection is more stable. The elastic wire can be bent from metal ...

Abstract

The invention discloses an attachable core-driven double-head powder shaft sleeve pickup. The attachable core-driven double-head powder shaft sleeve pickup is characterized by comprising a pickup part and a handle part. The pickup part is provided with a chuck and an elastic yarn. The handle part is provided with a core rod, the outer diameter of which is equal to that of a casing pipe. The upper end of the core rod is connected to a button, a threaded joint connected to a threaded connector is arranged at the lower end of the core rod, the lower end of the threaded joint presses the upper end of the casing pipe, a holding pipe externally sleeves the casing pipe and the core rod, a retraction edge is arranged at the inner edge of the lower end of the holding pipe, a boss is arranged on the upper part of the core rod, a compression spring sleeving the core rod is arranged between the boss and the retraction edge, a radial shaft is connected to the core rod above the compression ring, a longitudinal limiting chute is arranged on the side wall of the holding pipe, the end head of the radial shaft fits the longitudinal limiting chute, an ejector pipe is connected to the lower end of the holding pipe in a locking manner, a bottom plate is arranged at the lower end of the ejector pipe, and an opening where an stretch yarn extends downward is arranged on the bottom plate; the handle disclosed by the invention is easy to hold, the pressing operation is more convenient, and the handle is more stable and little to jitter if being released.

Description

technical field [0001] The invention relates to a tool for picking up a powder metallurgy bushing, in particular to a picker for a powder bushing driven by a live core at both ends. 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. [0003] During the production and installation of the existing metallurgical powder oil-containing bushing, because the ...
