Description

Flexible clamp for polishing fixed thin slice

Technical Field

The utility model provides an anchor clamps especially provide a flexible fixture that is used for polishing after fixed with probe piece, the light thin slice that monitoring and analysis field used, belongs to the machine-building technical field.

Background

When geological samples are analyzed in a laboratory, the minerals are usually made into a probe sheet and a light sheet so that the subsequent studies can be performed. The probe sheet is used for an electronic probe, the electronic probe achieves the purpose of electric conduction through gold plating or carbon plating during analysis, and then the domestic thickness standard of the probe sheet is about 60-80um after analysis. The light sheet is a light reflecting sheet for mineral phase identification. Rock slices are sheets used for microscopic evaluation, typically around 30um thick. The probe sheet and the optical sheet are required to be polished to a corresponding thickness before use, and an abrasive disc is required to be used in a polishing machine for polishing.

At present, no clamp specially used for clamping and fixing the thin sheet exists in the field, and most of the clamps are clamped, fixed and polished by using the existing metal sheet clamp. However, although the existing clamp has a large clamping amount per time and is convenient for sample loading and sampling, because the polished objects are all metal sheets and the precision requirement on the thickness is not high, the existing clamp adopts a rigid fixing and rigid grinding mode for polishing. This method is not suitable for probe sheets and optical sheets, and the rigid clamping is likely to cause damage to the sheet during polishing because the material is brittle. Secondly, the conventional clamping mode cannot meet the requirement of grinding precision due to the extremely small thickness of the probe sheet and the optical sheet.
