Electric generator bent axle machining technology

Abstract

The invention discloses a bent axle machining technology, particularly relates to an electric generator bent axle machining technology, and belongs to the technical field of bent axle machining and manufacturing. A segmented bent axle comprises front, middle and rear sections. The front, middle and rear sections are formed by connecting and assembling cone holes, which are matched with connectingarms in shaft neck taper, of connecting rod necks. Overall rough machining is carried out firstly; segmented semi-finishing is carried out after sawing; and overall precise machining is carried out after assembly to obtain a complete bent axle connecting rod assembly. Compared with the technology of segmented independent feeding and machining, during the overall rough machining, the problem of machining accuracy decrease caused by inconsistent positioning standards in segmented independent machining can be avoided to the greatest extent. The phase angle of the bent axle can be easily controlled during machining, and foundation is laid for accurate assembly connection of sections. Normal machining equipment is adopted during machining by the technology, and therefore requirements to the machining equipment are effectively lowered, and machining efficiency is improved.

Description

technical field [0001] The invention relates to a crankshaft processing technology, in particular to a generator crankshaft processing technology, and belongs to the technical field of crankshaft processing and manufacturing. Background technique [0002] The crankshaft is an important part of the engine. Generally, the crankshaft is an integral structure composed of the crankshaft head, the main journal, the sector plate and the connecting rod journal. The conventional crankshaft machining is integral machining, from rough machining to semi-finishing machining, and then to finishing machining. For these conventional crankshafts, the corresponding assembly parts (such as connecting rods) are bolted to the connecting rod journal of the crankshaft. There is no special feature in the structure of this type of crankshaft, and there is no weight-reducing hole on the journal inside the fan-shaped plate, etc. It can be processed by traditional techniques. [0003] There is also a ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned segmented crankshaft has high requirements on the machining accuracy of each segment and the matching degree of the overall assembly. The general processing adopts the process of rough machining to finish machining of each segment, that is, the front, middle and rear three segments of the crankshaft are As a separate component, three blanks are used for independent blanking until processed into the final product of each section, and then the final assembly of each section. In this processing technology, each section uses different reference planes for rough and fine machining. Positioning, it is easy to cause low precision after assembly of each section, which affects the overall performance of the crankshaft, and this processing method is inefficient
