Abstract

The invention provides a positioning milling tire. The positioning milling tire comprises a support body, a milling tire seat and a positioning pin, wherein a vertical installation through hole is formed on the top of the support body; an opening for one end of a blank material, which is to be machined into an end face spline, to extend out is formed on one side at the bottom of the support body; the support body is bolted to the top of the milling tire seat; a micro taper hole is formed on the top of the milling tire seat; a boss is formed at the bottom of the milling tire seat; the micro taper hole, the boss and the vertical installation through hole of the support body are coaxial; a T-shaped positioning groove with an outward opening is formed on the lateral part of the milling tire seat; and the positioning pin is arranged in the T-shaped positioning groove. The technical scheme of the invention overcomes the technical defect that the positioning milling tire has poor positioning precision on the blank material which is to be machined into a conversion circuit connecting rod for a transmission case in the prior art, and can assist in machining the conversion circuit connecting rod for the transmission case so as to meet the machining precision of the end face spline of the conversion circuit connecting rod for the transmission case.

Description

technical field [0001] The invention relates to the processing technology of mechanical parts, in particular to a positioning milling tire used for auxiliary processing of a connecting rod of a conversion circuit of a transmission box of an internal-combustion locomotive. Background technique [0002] As an important part of the transmission box in the diesel locomotive, the connecting rod of the transmission box conversion circuit has a slender shaft, a large turning diameter and high precision requirements for the end spline, so it plays a role in clamping the blank material during processing. Positioning tire milling has always been a subject of research by those skilled in the art. [0003] The positioning milling tire in the prior art is difficult to meet the requirements for auxiliary processing of the transmission box conversion circuit connection rod due to poor positioning accuracy of the blank material processed into the transmission box conversion circuit connecti...
