Nine-station machine tool for surface milling and drilling of taper sleeves and process of nine-station machine tool

Abstract

The invention discloses a nine-station machine tool for surface milling and drilling of taper sleeves. The nine-station machine tool comprises a machine body (1) and an oil-pressure toothed-type cutting platform (2). The oil-pressure toothed-type cutting platform (2) is rotationally mounted at the top of the machine body (1). Nine blank jigs (3) are arranged on the outer edge of the oil-pressure toothed-type cutting platform (2) evenly. A rough surface milling unit (4), a rough boring unit (5), a semi-fine boring unit (6), a fine surface milling unit (7), a fine boring unit (8), a drilling unit (9), a chamfering unit (10) and a tapping unit (11) are sequentially arranged at the top of the machine body (1) clockwise by taking the oil-pressure toothed-type cutting platform (2) as the circle center. The nine-station machine tool has the advantages of high processing accuracy, high automation degree, improved taper sleeve production efficiency, lowered labor intensity of workers and increased taper sleeve yield.

Description

technical field [0001] The invention relates to the technical field of taper sleeve processing, in particular to a nine-station machine tool for face milling and drilling of taper sleeves and its technology. 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. The versatility is very good, and it is suitable for various occasions. When the transmission part runs for a long time, the inner hole and the chain groove may be damaged. If the taper sleeve is used as the transmissio...

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 tap one of the holes, then enter the end face milling process, and finally carry out boring. However, each process requires repositioning of the tooling, and it is difficult to ensure the position accuracy between the holes, which eventually leads to The taper sleeve cannot be matched to the pulley. In addition, there are cumbersome operations, which makes it difficult to achieve continuous production, reduces production output, and cannot meet market demand.
