Grinding and polishing device for automatic grinding and polishing machine

Abstract

The invention discloses a grinding and polishing device for an automatic grinding and polishing machine. The grinding and polishing device comprises a disk trimming ring and a sample carrying disk. The disk trimming ring is of an up-down separating type structure, and the weight of an upper disk trimming ring body is smaller than that of a lower disk trimming ring body. A plurality of fixing holes are formed in the surface of the disk trimming ring. The fixing holes are distributed in the surface of the disk trimming ring in a central symmetry mode, or one of the fixing holes is formed in the center of the disk trimming ring and the remaining fixing holes are distributed in a central symmetry mode. A groove with the external diameter being smaller than that of the bottom of the disk trimming ring is formed in the bottom of the lower disk trimming ring body. A plurality of liquid drainage grooves are formed around the bottom of the disk trimming ring. The sample carrying disk and the fixing holes of the disk trimming ring are kept in clearance fit. By the adoption of the grinding and polishing device, a plurality of small samples can be ground and polished at the same time, so that efficiency is greatly improved, and the phenomenon that the polished surface is uneven due to abrasion of tooth blades of the disk trimming ring and lateral skewing of the samples is avoided. Meanwhile, when the samples with high hardness are ground and polished, grinding efficiency and quality can be improved by using a weight increasing body.

Description

technical field [0001] The invention relates to the field of mechanical equipment processing, in particular to a grinding and polishing device for an automatic grinding and polishing machine. Background technique [0002] In order to observe and study the relationship between the composition, structure and performance of some materials, metallographic analysis is required. The invention of the automatic grinding and polishing machine replaces the original manual polishing. It can mechanically and automatically grind and polish the samples to prepare conditions for metallographic analysis, which not only saves time but also improves work efficiency. The automatic grinding and polishing machine is mainly used for grinding and polishing the surface of the workpiece, and is often used in professional fields such as machinery, metallurgy and inorganic non-metals. [0003] The existing automatic grinding and polishing machine includes multiple parts such as a grinding and polishi...

Problems solved by technology

[0004] Technical problem: In order to solve the problem that the existing automatic grinding machine wears the polishing disc because the repairing ring is too heavy when grinding and polishing, the problem that the efficiency is too low when grinding and polishing hard samples, and the sample loading disc and the repairing ring When grinding and polishing a small sample with a small diameter, the sample’s polishing surface is uneven due to the large difference between the size of the sample and the size of the sample carrier. The invention provides a grinding and polishing device for an automatic grinding and polishing machine, which can be used for grinding Polish a single small sample or grind and polish multiple small samples at the same time, and ensure the grinding accuracy
