Mechanical electronic shell polishing plate

Abstract

The invention provides a mechanical electronic shell polishing plate. The mechanical electronic shell polishing plate comprises a polishing plate body, a fixing pin, a mounting groove, a supporting column, a filter net, connection rods, protection bars and a cooling chamber; mounting holes are formed in the left side and the right side of the interior of the polishing plate body; the fixing pin isinstalled in the mounting groove and penetrates through the polishing plate body to be connected with the lower side of the interior of the supporting column; the mounting groove is formed in the lower side of the interior of the polishing plate body; and the supporting column is installed in the middle of the upper end face of the polishing plate body. Through the design, the problem that original mechanical electronic shell polishing plates are not convenient to mount and dismount is solved, the filter net is installed on the left side of the interior of the cooling chamber, the connectionrods are installed on the left side and the right side of the annular side face of the supporting column, the protection bars are installed on the lower sides of the annular side faces of the connection rods, and the problem that the original mechanical electronic shell polishing plates have insufficiency in the fixing and protecting effects is solved through the design. The mechanical electronicshell polishing plate is reasonable in structure, high in stability, convenient to mount and dismount and high in reliability, and facilitates heat dissipation and protection.

Description

technical field [0001] The invention relates to a mechanical and electronic housing grinding disc, which belongs to the field of mechanical and electronic equipment. Background technique [0002] The grinding disc is a tool used for grinding metal parts and wooden parts. The grinding disc is generally composed of a grinding disc, an abrasive belt or sandpaper on the grinding disc. The grinding disc rotates, and the abrasive belt and sandpaper are used for grinding. After fine grinding, polishing is generally required. Usually, a grinding disc is required for the machining of mechanical and electronic housings. [0003] In the prior art, the existing mechanical and electronic shell grinding discs are not easy to load and unload, and the replacement of the grinding discs is relatively cumbersome, which affects the use effect of the grinding discs. At the same time, the existing mechanical and electronic housing grinding discs have insufficient fixed protection. It is inconven...

Problems solved by technology

[0003] In the prior art, the existing mechanical and electronic shell grinding discs are not easy to load and unload, and the replacement of the grinding discs is relatively cumbersome, which affects the use effect of the grinding discs. At the same time, the existing mechanical and electronic housing grinding discs have insufficient fixed protection. It is not easy to fix and after a long time of use, it will generate a high amount of heat, which will easily cause damage to the grinding disc and seriously affect the service life of the grinding disc. Now there is an urgent need for a mechanical and electronic housing grinding disc to solve the above problems
