Abstract

The invention discloses a slot wedge machining and positioning device and a using method thereof. The slot wedge machining and positioning device comprises a profile milling sequence positioning clamp used for positioning when profile milling is conducted on a slot wedge, and a matched milling sequence positioning clamp used for positioning when matched milling is conducted on the slot wedge. According to the slot wedge machining and positioning device and the using method thereof provided by the invention, the problems that in the prior art, full-sequence automatic machining of the slot wedge cannot be achieved, and the production efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of turbogenerators, in particular to a slot wedge processing and positioning device and a method for using the same. Background technique [0002] Rotor wedges (hereinafter referred to as slot wedges) are the core assembly components of large turbogenerators. They mainly play the role of ventilation and heat dissipation and stabilize the rotor structure. They are widely used in 300MW, 600MW, and 1000MW turbogenerators. The stable, safe and efficient operation of the unit has an important impact, and the economic value is great. [0003] In the existing technology, slot wedge processing is mainly based on single-machine CNC machining, using customized special tooling or vises for clamping and positioning, and multiple links such as loading, positioning, clamping, loosening, retrieving and inter-sequence transfer. It is still inseparable from the participation of people, and the repetitive labor is heavy, whi...
