A method for grinding and polishing platinum vessels using an automatic platinum vessel grinding and polishing machine

Abstract

The invention relates to a platinum vessel automatic polishing machine and a method. The platinum vessel automatic polishing machine is formed by a protective cover, a workbench, a machine head, a main motor, a polishing machine fixing shaft, a polishing machine main shaft, a lock head, a polishing head, a lifting control rod, a fixing sleeve, a crucible fixing sleeve, a fixing sleeve motor, a limiter, a driving wheel, a driven wheel and a belt; the main motor is fixed on a rear plate of the protective cover; the driving wheel is fixed on a main motor shaft; the driven wheel is driven by the driving wheel through the belt; the lower end of the polishing machine main shaft is connected with the lock head. The polishing method comprises driving the polishing head by the main motor for forward polishing; controlling the speed of the fixing sleeve motor; performing backward polishing from slow to fast. The platinum vessel automatic polishing machine and the method are suitable for the precise analysis and detection field and the platinum vessel treatment, the operation is simple, convenient and safe, the high cost caused by remelting is saved, the deformation of workpieces after grinding is not produced, the damage to the surface is not produced, the accuracy is not affected, the cost is low, the speed is high, the operation can be achieved in about two minutes, and the working efficiency and the polishing effect are greatly improved in comparison with the manual polishing.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to a method for grinding and polishing platinum vessels by using an automatic platinum vessel grinding and polishing machine, which is suitable for the grinding and polishing of platinum vessels and formers in the field of analysis and detection. Background technique [0002] In the analysis and testing of import and export commodities, especially in the testing of chemical and mineral products, it is necessary to prepare glass samples in a high temperature and corrosive environment, and the platinum crucible has a melting point as high as 1772 ° C, stable chemical properties, and can be burned in air. It does not absorb moisture and other characteristics, so it is an indispensable appliance in the sample preparation process. [0003] However, even if the platinum crucible is used in a high temperature and corrosive environment for a long time, corrosion, scratches, deformation, etc. w...

Problems solved by technology

[0005] If you want to reduce this kind of loss, you can improve the surface finish of platinum utensils by grinding and polishing the platinum utensils with corrosion, scratches and deformation, remove scratches, prolong the primary service life of platinum utensils, and reduce the weight of platinum utensils. The number of times of melting and the loss caused by remelting, and currently there is no special equipment for polishing platinum vessels in China; therefore, how to solve this problem has become a subject to be studied and solved by those skilled in the art
