Abstract

The invention discloses a boring rod component for machining a thrust surface of a diesel body, which comprises a driving rod, a push rod, a slider and a return spring. A boring rod is in a hollow structure, a backing positioning nut and a thrust surface axial positioning nut are arranged at the rear end of the boring rod, the driving rod, the push rod and the return spring are sequentially arranged in a hollow cavity of the boring rod, the driving rod is connected with the boring rod through a feather key, and the driving rod is kept in contact with the push rod under the action of the return spring. The slider is arranged on the boring rod and corresponds to an oblique protruding strip on the push rod through an oblique groove, and radial turning tools in pair are arranged at the top of the boring rod. The boring rod component has the advantages that the feather key is used for the driving structure to simply combine torque transmission with feeding, the tool is withdrawn first and then the boring rod is pulled out when the spring is returned, and the push rod is combined with the radial slider through the oblique groove, so that the boring rod component is high in rigidity and machining manufacturability.

Description

technical field [0001] The invention belongs to the field of metal cutting machine tools, relates to a tool component for metal cutting machine tool processing, and is a tool component that can be used as a standard component of a machine tool, in particular to a boring bar component for processing the thrust surface of a diesel engine body. Background technique [0002] The machining of the thrust surface of the crankshaft of the diesel engine body usually requires a special boring bar to achieve axial positioning in mass production, and has the function of simultaneous radial turning on both sides. The operation of the boring bar must ensure the surface roughness of the processed part, the perpendicularity of the surface relative to the axis of the main bearing hole, the outer diameter of the thrust surface and other processing requirements. The existing diesel engine body crankshaft thrust surface processing adopts a rack and pinion structure, such as figure 1 As shown, ...
