Abstract

The invention provides a machining fixture and method of eccentric bushings for cone crushers. The fixture comprises a mandrel and a pressure plate matching with the mandrel. Two ends of the mandrel are provided with a small cone frustum and a cylinder respectively. The middle of the mandrel is provided with a large cone frustum. The cylinder is provided with a first ejector pin hole. The small cone frustum is provided with a second ejector pin hole. The pressure plate is provided with a third ejector pin hole. The axis penetrating the first ejector pin hole and the second ejector hole and the axis penetrating the first ejector pin hole and the third ejector pin hole form a first included angle; the axis of the outer surface of an eccentric bushing and the axis of the inner surface of the eccentric bushing form a second included angle; the first included angle and the second included angle are different. The machining fixture and method of eccentric bushings for cone crushers has the advantages that machining precision of eccentric bushings is guaranteed effectively, operational reliability of the cone crusher with the eccentric bushing machined by the method is improved, efficient operation of the cone crusher can be guaranteed, yield is increased, and consumption is lowered.

Description

technical field [0001] The invention relates to a processing tool for an eccentric sleeve of a cone crusher and a processing method for the eccentric sleeve in the field of mechanical processing. Background technique [0002] The eccentric sleeve is a key part of the cone crusher. The machining accuracy and shape and position tolerance of the eccentric sleeve directly affect whether the crusher can operate normally. The outer surface of the eccentric sleeve is a cylindrical surface, the inner surface is a conical surface, and the inner hole of the eccentric sleeve runs through the eccentric sleeve. The axis of the outer surface of the eccentric sleeve intersects the axis of the inner surface of the eccentric sleeve. During the processing of the eccentric sleeve, it is required to ensure that the above two axes intersect at a specified angle. At present, no matter whether the processing plants adopt the process of processing the inner hole first or the process of processing...
