an adsorber

Abstract

The invention relates to the technical field of machining, in particular to an adsorber. The adsorber comprises an outer sleeve without a bottom cover, an adsorption unit and a magnetism conducting cover. A guiding hole is formed in the end face of the top end of the outer sleeve. Threads are arranged inside the outer sleeve. The magnetism conducting cover is fixedly connected with the bottom end of the outer sleeve. One end of the adsorption unit is arranged inside the outer sleeve, and the other end of the adsorption unit penetrates through the guiding hole and then is arranged outside of the upper end of the outer sleeve. According to the adsorber, due to the fact that the adsorption unit has large adsorption force to a sheet steel sample, the accident that the sheet steel sample is separated and flies off cannot happen, and safety of operating staff is guaranteed. Due to the fact that the sheet steel sample is stressed in a balanced mode, deformation of the sheet steel sample cannot happen, and the polishing quality of the surface of the sheet steel sample is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an adsorber. Background technique [0002] The existing methods of grinding and polishing samples mainly include three methods: direct hand-holding, mechanical clamping and resin inlaying. However, for the thin steel plate plane, the existing methods have the following problems: First, for the thin steel plate plane direction When grinding and polishing, because the thickness is too thin, it cannot be held directly; second, in some cases, the front and back of the thin steel plate are the surfaces to be processed, and the mechanical fixture cannot be used, and the thickness is too thin. On the one hand, the flatness of the sample may be affected by the deformation caused by the force, which is not conducive to the subsequent test; third, the resin inlay method has pressure during the inlay process, which will cause the deformation of the thin steel plate plane.

[0002] The existing methods of grinding and polishing samples mainly include three methods: direct hand-holding, mechanical clamping and resin inlaying. However, for the thin steel plate plane, the existing methods have the following problems: First, for the thin steel plate plane direction When grinding and polishing, because the thickness is too thin, it cannot be held directly; second, in some cases, the front and back of the thin steel plate are the surfaces to be processed, and the mechanical fixture cannot be used, and the thickness is too thin. On the one hand, the flatness of the sample may be affected by the deformation caused by the force, which is not conducive to the subsequent test; third, the resin inlay method has pressure during the inlay process, which will cause the deformation of the thin steel plate plane. It is not economical from a cost point of view

In addition, the use of direct hand-holding or mechanical clamping may cause safety accidents such as abrasions, scratches, and the sample flying out during the grinding and polishing process due to too small or uneven force.
