Magnetic tool

Abstract

The invention discloses a magnetic tool, which comprises a magnetic body, wherein the magnetic body is embedded into a shielded casing with an opening in the bottom end; a pull rod is connected with the top of the shielded casing; the diameter of the opening in the bottom end of the shielded is smaller than that of the bottom end of the magnetic body. According to the invention, the magnetic field of the magnetic body is shielded except that of the bottom end, so that the magnetic body can effectively, completely and quickly attract a great amount of scraps, drosses, and other small iron castings in a narrow and small space such as a deep hole or a groove with a strong force; the reliability is good; moreover, the magnetic body can be reliably and stably embedded into the shielded casing, so that the structural strength is high, the magnetic body cannot fall off from the shielded body however big the attraction force between the magnetic force and the metal part is, the probability of failures is low, the practicability is strong, and the service life is long.

Description

technical field [0001] The invention relates to an iron-absorbing tool, which is especially suitable for removing small iron pieces such as iron filings and iron slag in narrow spaces such as deep holes and grooves, and is also suitable for removing iron filings and iron slag on wide surfaces. Small iron pieces are removed. Background technique [0002] In the machining process, various deep holes (or grooves) are usually processed on the metal parts for the next processing or installation of various metal parts. Due to the narrow space of the deep holes on the metal parts, various iron filings generated during the processing remain in the deep holes, and it is very difficult to remove them. At present, the conventional removal methods include compressed air blowing method, vacuum cleaner method and dough sticking method; among them, compressed air blowing method and vacuum cleaner method cannot be completely removed, and the removal effect is poor, which not only affects t...

AI Technical Summary

Problems solved by technology

The airtight casing of this magnetic iron-absorbing tool will not only greatly discount the adsorption force of the magnetic body, but also affect the excellent adsorption effect of the magnetic body itself; Made of magnetically permeable materials, the magnetic field of the magnetic body cannot be shielded, so that the magnetic body will absorb the metal parts themselves while absorbing iron filings, especially when preparing to enter deep holes (or grooves), magnetic iron absorption The tool forms adsorption on the metal parts at the hole itself, and cannot easily and effectively extend into the deep hole. However, a large amount of iron filings in the deep hole of the metal part is just left at the bottom of the hole. This contradictory phenomenon makes Magnetic iron-absorbing tools are very difficult to operate, poor in reliability and practicability, and low in adsorption and removal efficiency
