Problems solved by technology

At present, the relevant tooling in the workshop is made of rigid expansion sleeves. The diameter range of the outer circle that can be clamped by the rigid expansion sleeves is very small. Basically, each part corresponds to a set of fixtures. It takes a long time to install, unload, and adjust when changing production, which affects the output of the production line.

Abstract

The invention discloses an externally-tightening and quick-changing hobbing tool for shafts. The externally-tightening and quick-changing hobbing tool comprises a base installed on a work plane of a machine tool. A transition pull plate and an adhesion tightening sleeve are sequentially installed on the base. The transition pull plate is connected to a pull rod of the machine tool and driven by the pull rod of the machine tool to move downwards or upwards. The adhesion tightening sleeve is matched with the transition pull plate to tighten or loosen work-pieces. According to the characteristics that power takeoff shafts are various and production change is frequent, the externally-tightening and quick-changing hobbing tool is designed. According to the tool, serialization design is carried out on the adhesion tightening sleeve and a centre, the adhesion tightening sleeve and the centre are convenient to change, and the design range of clamps for new shaft parts in future can be expanded.

Description

【Technical field】 [0001] The invention belongs to the technical field of mechanical processing, and relates to a production changing tool, in particular to an outwardly expanding quick-change gear hobbing tool for shafts. 【Background technique】 [0002] At present, there are many types of power take-off products, and the output shafts and hollow shafts of various power take-offs are all arranged on the same production line for production, and the frequency of replacement is very high. Moreover, the outer circles, lengths, and center hole positioning dimensions of different axes are often inconsistent. At present, the relevant tooling in the workshop is made of rigid expansion sleeves. The diameter range of the outer circle that can be clamped by the rigid expansion sleeves is extremely small. Basically, each part corresponds to a set of fixtures. It takes a long time to install, unload, and adjust when changing production, which affects the output of the production line. . ...
