Mill pinlon tool

Abstract

The invention relates to a mill pinlon tool. The mill pinlon tool comprises a mandrel and a conical sleeve. One end of the mandrel is sequentially provided with a shoulder, a conical table and a bolt part from inside to outside, the conical table is sleeved with the conical sleeve, one end of the conical sleeve abuts against the shoulder, and the other end of the conical sleeve is connected with the bolt part in a screwing mode through a nut for compression. The nut presses the other end of the conical sleeve through a gasket. An elastic cushion is arranged between the nut and the gasket, and the conical sleeve is connected with the conical table through a key. The conical sleeve is externally connected with a mill pinlon inner ring, one end of the conical sleeve abuts against the shoulder through a mill pinlon, the other end of the conical sleeve is connected with the bolt part in the screwing mode through the nut for compression, and then the mill pinlon is fixed to the mandrel, positioning is stable and firm, the elastic cushion and the gasket are matched, and the stability performance is further improved. The spatial position of the mill pinlon can be adjusted through installing and positioning of the mandrel, and the displacement requirements of hobbing and gear grinding are met. The conical sleeve can be selected and used according to different mill pinlon inner rings, meets the machining requirements of mill pinlons of different sizes and types and is wide in application range.

Description

technical field [0001] The invention relates to a gear processing tool, in particular to a tool for processing gear teeth. Background technique [0002] The gear is a gear with a small number of teeth. When the number of teeth is small, the tooth top of the tool goes too deep into the base circle of the gear during gear hobbing, which will easily cause undercutting at the tooth root of the gear. When designing the wheel, it is necessary to reserve the undercut amount. At the same time, it is necessary to consider that the tooth root of the Shao wheel will expand after heat treatment. In order to meet the grinding allowance, the gear displacement is usually used to prevent the undercut amount of the Shao wheel from being too large and avoid damage. For gears, the existing gear clamping tools cannot meet the gear displacement of hobbing processing. Contents of the invention [0003] Aiming at the clamping problem of Shaolun processing in the prior art, the present invent...
