A system for producing taper sleeves and its production process

Abstract

The invention discloses a system for producing a taper sleeve. The system comprises a nine-station machine tool, a groove processing machine tool and a key slot processing machine tool. The invention further discloses a machining technique for the taper sleeve. The system and technique for producing the taper sleeve have the beneficial effects that the smoothness of the outer surface of the taper sleeve is protected, the degree of automation is high, assembling of the taper sleeve is achieved quickly, the machining precision is high, the taper sleeve production efficiency is improved, the labor intensity of workers is relieved, and the taper sleeve production capacity is improved.

Description

technical field [0001] The invention relates to the technical field of taper sleeve production, in particular to a system for producing taper sleeves and a production process thereof. Background technique [0002] The taper sleeve is a new type of mechanical transmission connection component commonly used in European and American countries. It has the characteristics of high standardization, high precision, compact structure, and convenient installation and disassembly. Through the 8-degree outer cone surface and the inner cone surface of the pulley, sprocket and other transmission parts, the centering accuracy of various transmission parts is greatly improved. The size of the taper sleeve is designed according to the series standard. Versatile and interchangeable, it is suitable for various occasions. When the transmission part runs for a long time, the inner hole and the keyway may be damaged. If the taper sleeve is used as the transmission part, when this happens, you on...

Problems solved by technology

[0004] In order to realize the processing of two half-shaped light holes 50 and one half-shaped threaded hole 51 on the tapered sleeve, a single process is usually used for processing, that is, firstly use a drilling machine to drill three holes on the large end surface of the blank, and then use a tapping machine to drill three holes. Tap one of the holes, then enter the face milling process, and finally carry out boring. However, each process needs to reposition the tooling. It is difficult to ensure the position accuracy between the holes, and finally the taper sleeve after processing cannot be matched. To the pulley, in addition, there are cumbersome operations, it is difficult to achieve continuous production, which reduces the production output and cannot meet the needs of the market

[0005] In addition, the central hole of the taper sleeve is provided with a keyway 53, and the outer wall of the taper sleeve is also provided with a groove 52. Only by radially squeezing the taper sleeve to make it slightly shrink can the taper sleeve enter the pulley correctly. The groove method is cut manually with a saw blade. Every time a groove is sawed, it needs to be repositioned, which greatly increases the labor intensity of the workers and reduces the production efficiency of the taper sleeve.
