Description

Technical Field

[0001] This utility model relates to the field of precision machining technology for cemented carbide tools, specifically an automatic feeding and connection device for grinding cemented carbide teeth. Background Technology

[0002] Hard alloy is a hard material made by mixing hard particles of a certain refractory metal carbide with one or more iron group elements and then manufacturing it through powder metallurgy. Mining tools and drilling tools are usually made of cemented carbide to ensure their hardness. During the manufacturing process, they need to undergo precision external cylindrical grinding to ensure their performance. These workpieces are valuable, have high hardness, and usually have specific shapes, so it is necessary to distinguish between the front and back sides for grinding. Currently, processing in this field requires manual operation for feeding, orientation recognition, and clamping, resulting in low efficiency. Furthermore, the carbide dust is harmful to the health of operators. Alloy teeth need to enter the grinding machine in the correct orientation, and manual identification and placement are not only slow but also prone to errors, leading to a higher scrap rate. In addition, some existing automated feeding devices lack intelligent detection functions, cannot effectively distinguish the front and back of the workpiece, or can only serve a single machine, making it difficult to form a continuous production line. Overall production efficiency is bottlenecked, and it is difficult to quickly adapt to mixed production of different specifications of alloy teeth. Utility Model Content
