Abstract

The invention discloses a micro-cutting sample mounting experiment table based on microscopic observation, the experiment table is mainly characterized in that the vertical height of a microscope is controlled by adjusting a lifting hand wheel (5), focusing is achieved, a lower adjustable LED light source (3) adjusts the brightness of the light source, the magnification factor of the microscope is adjusted through a zoom lens (4), and a displayer (8) is connected with an electronic camera (6), and images can be directly transmitted to mobile communication equipment, so that microscopic observation of the fine cuttings is realized. A supporting handle (12) is connected with the supporting base through a five-degree-of-freedom spherical hinge, the precise clamp holder (10) is connected with the supporting handle (12) in a hinged mode, and the combination of the supporting handle (12) and the precise clamp holder (10) can improve the clamping stability of the fine cuttings and accurately control the angle and the position of the fine cuttings. The platform can realize accurate sample preparation and perform preliminary observation on the sample, so that the accuracy of sample preparation and the utilization rate of equipment are effectively improved.

Description

technical field [0001] The invention is a microscopic observation-based experimental platform for mounting microscopic chips. Background technique [0002] It is an important research direction in the field of manufacturing to study the machinability of materials, choose a reasonable processing technology, and improve processing quality and processing efficiency. The study of chip deformation and chip morphology by metal cutting experiments is a common method for machinability research, so chip sample preparation is an essential work. Turning and milling are the most commonly used metalworking methods. The chip shape of turning machining is relatively regular. Under the condition of rough machining process parameters, the chip size is relatively large, and the mounting sample is relatively simple. However, under the condition of precision machining, the turning chip size is relatively small, and the chip tilting problem often occurs when observing the mounting sample with t...
