Abstract

The invention discloses a tool special for rolling a small hole through a lathe. The tool comprises a Morse taper shank (1), a roller pin holder (2) mounted at one end of the Morse taper shank (1) and roller pins (3) mounted at the right end of the roller pin holder (2). The roller pins (3) are fixed to the Morse taper shank (1) through a press cap (4), a gasket (5) and a compression bolt (6). The tool special for rolling the small hole through the lathe is reasonable in structural design, convenient to operate and high in work efficiency; the form and location tolerance of a machined workpiece is small, and the defects of horn mouths and the like are not prone to being formed; and the machined small hole workpiece is high in quality, precision and practicality.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a special tool for lathe rolling small holes. Background technique [0002] In the prior art, it is often necessary to process workpieces with small holes. In the prior art, turning is performed first, and then grinding is performed. For example, tapered diamond grinding is used for grinding. The shape and position tolerance of the workpiece obtained after processing is relatively large, and manual grinding is required. It is easy to form defects such as bell mouth, and the quality of the processed workpiece is low, the precision is low, and it cannot meet the high standard. [0003] Therefore, it is very necessary on the basis of the prior art to research and develop a kind of structure design reasonable, easy to use, high work efficiency, the shape and position tolerance of the workpiece obtained after processing is small, and it is not easy to form defects such as bell mouth, and the wor...
