Intelligent automatic metallographic grinding and polishing machine

Abstract

The invention discloses an intelligent automatic metallographic grinding and polishing machine, and relates to grinding and polishing machines. The upper portion of a movable polished shaft (5) is fixed to a main machine frame (1) through a left-right transmission lead screw (12). A grinding head set (26) is installed on the movable polished shaft (5). A grinding material box (7) is installed at the upper portion of the grinding head set (26). The left side of the grinding material box (7) is connected with a charging pump (10). The grinding head set (26) is internally provided with a grinding head rotating motor (8). The middle of the right side inside the main machine frame (1) is provided with a polishing disc (2). An accurate grinding disc (17) is installed above an accurate grinding motor (21). The left side inside the main machine frame (1) is provided with a drainage tube (19). The lower portion of the main machine frame (1) is internally provided with a PLC (22). According to the intelligent automatic metallographic grinding and polishing machine, a colorful touch screen and the PLC are adopted for control, the degree of automation is high, the full-automatic intelligent operation is achieved in the whole grinding and polishing process, the working intensity of operators is relieved, and working efficiency is greatly improved.

Description

[0001] Technical field: [0002] The invention relates to a grinding and polishing machine, in particular to a novel intelligent automatic metallographic grinding and polishing machine. Background technique: [0003] The existing domestic automatic metallographic grinding and polishing machines are mainly divided into two types: single-disc and double-disc, and the entire grinding and polishing process cannot be completed automatically (for example, the single-disc automatic metallographic grinding and polishing machine needs to be shut down and replaced after the sandpaper is ground. Fine-grained sandpaper and polishing cloth, and then set the working parameters; after the double-disc automatic metallographic grinding and polishing machine is finished, it is necessary to manually move the grinding and polishing head to the polishing position, and then set the polishing parameters, etc.). The setting of the pressure is also mostly mechanical loading. There is no load cell to...

Problems solved by technology

[0003] The existing domestic automatic metallographic grinding and polishing machines are mainly divided into two types: single-disc and double-disc, and the entire grinding and polishing process cannot be completed automatically (for example, the single-disc automatic metallographic grinding and polishing machine needs to be shut down and replaced after the sandpaper is ground. Fine-grained sandpaper and polishing cloth, and then set the working parameters; after the grinding is completed, the automatic metallographic grinding and polishing machine with double discs needs to manually move the grinding and polishing head to the polishing position, and then set the polishing parameters, etc.)

The setting of the pressure is also mostly mechanical loading. There is no load cell to accurately collect the pressure value, and the loading pressure during the grinding and polishing process cannot be adjusted in preparation; and the addition of abrasives during the entire grinding and polishing process cannot be done. Until the programmed automatic control is completed (mostly adopt the mechanical drip type, and need to manually control the feeding time and flow)

It is far from satisfying the complex precision grinding and polishing of some new process materials
