Bearing inner and outer ring grinding automatic line

Abstract

The invention relates to an automatic grinding line for inner and outer rings of bearings, which includes an inner ring wire and an outer ring wire. The inner ring line is connected with a fully automatic ball bearing inner ring groove grinder, a fully automatic ball bearing inner circle grinder and a fully automatic inner diameter pneumatic Out-of-machine testing machine, fully automatic ball bearing inner ring groove superfinishing machine; outer ring groove grinder and outer ring groove superfinishing machine are connected on the outer ring line, and ARM9-based The main processor of the core, the main processor based on the ARM9 core is connected with a peripheral power drive circuit, a sensing signal receiving isolation circuit, and a software platform is integrated in the main processor based on the ARM9 core. The invention adopts advanced numerical control technology, pneumatic full-automatic online detection device, interchangeable fixture technology and improved device, has the functions of online tracking and detection of workpiece processing status, automatic loading and unloading, etc., strong grinding rigidity, flexible and reliable operation, and high production efficiency , low noise, high processing precision.

Description

technical field [0001] The invention relates to an automatic grinding line for bearing inner and outer rings, belonging to the technical field of bearing processing. Background technique [0002] At present, the research on the automatic bearing grinding production line mainly focuses on the production automation of a single equipment, while ignoring the network structure. Most of the automatic bearing grinding production lines in my country are relatively old and do not have equipment operation status monitoring and communication interfaces. For this reason, the running state data of the bearing grinding automatic production line is usually observed manually, entered manually, and then statistically and analyzed through relevant software. This management mode is inefficient and error-prone, and it is difficult to realize the overall real-time monitoring and management of the bearing grinding automatic production line, resulting in the inability of real-time and accurate fee...

AI Technical Summary

Problems solved by technology

[0003] In the mechanical grinding industry, as an automatic machine tool for bearing ring grinding, it has brought a lot of benefits to many bearing factories, but in today's increasingly fierce competition, due to the lack of automation of this type of automatic machine tool High, resulting in low production efficiency, low pass rate, difficult maintenance of machine tools, etc., can no longer meet the requirements of many bearing manufacturers

In the current mechanical grinding and processing bearing ring industry, there are mainly the following problems: (1) low production efficiency

Basically, single machines are used for production, with low production efficiency and high product scrap rate, while foreign countries basically use automatic in-line grinding processing methods, and the production efficiency in the same processing time is 1.5 times to 2 times that of domestic ones. More

(2) Poor product quality

The existing automatic connection equipment of bearing manufacturers is still a labor-intensive industry because of its late development. Requirements for process control in bearing production

(3) poor security

[0005] At present, although domestic similar grinding machines adopt the electromechanical integration control system, due to the high price and high maintenance cost, they cannot obtain good economic benefits. grinding machine, and it is very necessary to carry out technical transformation of traditional equipment

[0006] At present, there have been many automatic machine tools for bearing ring grinding and processing in China, but most of them are based on traditional technology to realize automation. The degree of automation is not high, and the efficiency is low, which cannot meet the requirements of various bearing production units. And there is very little development of automatic lines with a high degree of automation, especially companies using CNC automatic lines, which are almost still in their infancy
