Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary structures for machining a steering knuckle through a lathe, and more specifically, particularly relates to a steering knuckle quick positioning fixture for a lathe. Background Art

[0002] The steering knuckle, also known as the "ram's horn", is one of the important parts in the automobile steering axle. It can make the car run stably and sensitively transmit the driving direction. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to turn the car. When the car is driving, it is subjected to variable impact loads. Therefore, it is required to have very high strength. The production of steering knuckles requires the use of lathes, which are machine tools that mainly use turning tools to turn rotating workpieces.

[0003] Based on the above, the steering knuckle currently needs to be turned, drilled and other processing operations on a lathe during production and processing, but most fixtures are difficult to carry out rapid assembly of the steering knuckle and the lathe, and can only perform processing and fixing of the steering knuckle in a single position, making it inconvenient for a single fixed installation fixture to carry out multi-state processing of the steering knuckle, affecting the efficiency of continuous processing of the steering knuckle.
