Abstract

A special-purpose tool for machining flange holes is applied to positioning internal diameters of machined holes. The present machining technology adopts the method of firstly marking and then drilling. The alignment and clamping operations are need to be carried out many times during marking and drilling operations, therefore production requirements cannot be met. In order to overcome the above problem, the tool is composed of a base, a thin nut, a drill plate, a drill sleeve, a positioning sleeve, a thick nut, a centering pin, and a positioning pin and other components. The tool is characterized in that connection of base, the components, the drill plate and the positioning sleeve is achieved by the centering pin and nuts. Components of the flange are positioned by using the centering pin and the positioning pin. The chucking and loosing operations of a workpiece are finished by using the nuts. The workpiece is clamped for one time by adopting the tool and is machined without marking. The special-purpose tool for machining flange holes is simple in structure, convenient in operation, and can meet the production requirement.

Description

A kind of special tooling of processing hole on the flange
Technical field
