Abstract

The invention relates to a dowel pin sleeve, which comprises a positioning sleeve and a pin, wherein the positioning sleeve and the pin are processed into a whole by the forging technology; a connected and combined dowel pin sleeve is fixed by forging; and the sleeve is manufactured by the aluminium alloy material via the metal die forging forming technology. The pin has the advantages of simple structure, light weight, convenience in installation, safety and reliability due to being manufactured by the copper alloy bar machine processing technology, the problem of electro erosion generated by the riveting connection of the dowel pin sleeve and a locator rectangular tube is effectively solved, and the high-speed use requirement of an electrified railway is satisfied.

Description

technical field [0001] The invention relates to a positioning pin sleeve, which belongs to the technical field of electrified railway catenary parts manufacturing. Background technique [0002] The positioner in the catenary positioning device of the electrified railway high-speed dedicated line is made of aluminum alloy rectangular pipe. One end of the positioner is riveted to fix the positioning hook of the belt hook part, and the other end is riveted to fix the positioning sleeve pin. The positioning sleeve pin is connected with the positioning line clamp to fix the contact line. Location. The currently used locating pin sleeve includes a locating sleeve and a pin, wherein the locating sleeve and the pin are connected as a whole by a rivet, and since the locating sleeve and the pin are connected as a whole by a rivet, it is easy to use Corrosion occurs; in addition, the positioning sleeve and pin are die forgings made of copper alloy or steel, and the parts of the two ma...
