Pipe fitting fixing device for grinding outer circle of fragile thin-wall pipe fitting

Abstract

The invention provides a pipe fitting fixing device for grinding an outer circle of a fragile thin-wall pipe fitting, and relates to the technical field of new materials. An air bag (9) is arranged onthe outer edge surface of a support shaft (4); compressed air is filled from an air inlet of a rotating joint and enters an air inlet (5) of the support shaft; the compressed air is diverted by an air bag inlet hole (10) in an inlet hole and then respectively enters the air bag; and under the action of pressure, the air bag expands and supports a pipe fitting (8) to be ground, thereby realizing the flexible connection of the support shaft and the pipe fitting, providing auxiliary support for pipe fitting processing, and counteracting the cutting resistance generated in the processing and thelike. The pipe fitting fixing device for grinding the outer circle of the fragile thin-wall pipe fitting provided by the invention has the advantages of being simple in structure, high in production efficiency, low in cost, reasonable in structural design and the like, and is particularly suitable for wind range of popularization and application.

Description

[0001] [Technical Field] The present invention relates to the technical field of new materials, in particular to a pipe fixing device for grinding the outer circle of fragile thin-walled pipes. 【Background technique】 [0002] It is known that the new material industry has the characteristics of highly intensive technology, high investment in research and development, high added value of products, strong internationalization of production and markets, wide application range, and good development prospects. Its research and development level and industrialization scale It has become an important symbol to measure a country's economic, social development, scientific and technological progress and national defense strength. All countries in the world, especially developed countries, attach great importance to the development of new material industry.

Problems solved by technology

Taking the target as an example, the sputtering coating process based on the principle of physical vapor deposition has been widely used in liquid crystal display equipment, solar cells, solar vacuum tubes, semiconductor chips and other technical fields; while the rotating target is commonly used in the sputtering coating process. A kind of coating consumable, the rotary target is generally composed of a tubular metal substrate and a coating material layer. The normal practice is to directly spray the coating material layer on the outer surface of the tubular metal substrate after surface cleaning or sand blowing. This product exists The problem is that the bonding strength between the coating material layer and the outer surface of the tubular metal substrate is poor, which will affect the normal service life of the rotary target in the sputtering coating process; at the same time, due to the specific requirements of the spraying process, the silicon powder used Insufficient purity, which leads to lower overall purity of the target and affects the coating quality

[0003] Another process is to use a hollow tube material on a complete ingot or rod-shaped material, and bind the tube material to the tubular metal substrate after grinding and polishing. This process has low production efficiency. , the production cost is high, and due to the short length of the pipe material due to the limitation of the digging process, the cost limitation cannot be widely promoted and applied. Therefore, the device for drawing tubular crystals has become the research direction of those skilled in the art. When the tubular crystal After the crystal is drawn, it is necessary to grind the inner circle and the outer circle of the tubular crystal to make the tubular crystal meet the technical requirements. Then, how to provide a pipe fixing device for grinding the outer circle of the fragile thin-walled pipe becomes a problem. Long-term technical demands of those skilled in the art
