Description

Technical Field

[0001] The invention relates to the technical field of metal workpiece processing, in particular to a metal workpiece surface grinding device. Background Art

[0002] When metal workpieces are processed, their surfaces need to be polished and ground. Grinding refers to embedding or coating abrasives on the surface of the grinding tool to create relative movement between the grinding tool and the processed surface, and applying a certain amount of pressure to remove the tiny surface protrusions on the workpiece to obtain a higher surface accuracy grade and dimensional accuracy.

[0003] In the process of grinding metal workpieces, in order to improve the grinding effect of metal workpieces, grinding fluid must be continuously added during the grinding process. The grinding fluid is continuously added and eventually falls into the collection box. The grinding fluid that flows into the collection box contains impurities. The impurities accumulate on the surface of the filter, which easily causes it to be blocked, thereby reducing the permeability of the filter and affecting the efficiency of subsequent grinding fluid entering the collection box.

Cleaning impurities under filtration can prevent the filter 50 from being clogged by impurities after long-term use, and is convenient for cleaning impurities on the top of the filter 50. During the cleaning process, with the cooperation of the knocking assembly 9, several knocking plates 98 can repeatedly knock on the bottom of the guide plate 60 to avoid impurities from accumulating on the top of the guide plate 60, which is convenient for cleaning impurities. The cleaned impurities on the rear side fall into the inner cavity of the collecting tank 70.
