Problems solved by technology

In the existing arm processing technology, the assembly process of the flat arm and the inclined arm is a difficult point. In order to ensure the smooth installation of the pin shaft and the cotter pin, very high control precision and multiple adjustment processes are required. The existing There is no equipment that can realize automatic assembly in the technology, so manual assembly is used, and the efficiency is very low

Abstract

A horizontal and inclined cantilever assembling device for simplified unified cantilever machining is used for connecting a horizontal cantilever and an inclined cantilever in a simplified unified cantilever; and the horizontal cantilever and the inclined cantilever are connected through a hinge pin, and the hinge pin is detachably connected with a snap pin. The horizontal and inclined cantileverassembling device comprises a hinge pin control mechanism and a snap pin control mechanism; the hinge pin control mechanism comprises a plurality of hinge pin transferring grip jaws; and the snap pincontrol mechanism comprises a second snap pin push rod and a movably-arranged snap pin slideway, the second snap pin push rod faces towards the lower portion of the joint between the horizontal cantilever and the inclined cantilever, the snap pin slideway and the second snap pin push rod are parallel to each other, and the snap pin slideway corresponds to the second snap pin push rod or is staggered with the second snap pin push rod in the sliding process. The horizontal and inclined cantilever assembling device for simplified unified cantilever machining can complete installing of the hinge pin and the snap pin, and accordingly achieve assembling of the horizontal cantilever and the inclined cantilever.

Description

technical field [0001] The invention relates to the technical field of wrist and arm processing, in particular to a simplified horizontal and inclined wrist arm assembly device for wrist and arm processing. Background technique [0002] In the traction power supply system, the wrist arm is an important part of the catenary. The wrist arm is usually installed on the upper part of the pillar to support the contact suspension and play the role of load transmission. The wrist arm is generally made of circular steel pipes with a length of It is related to factors such as the structural height of the contact suspension, the side boundary of the pillar, and the location of the pillar. With the development of technology, the structure of the wrist arm is also constantly changing, and the simplified wrist arm has gradually begun to be used. The simplified wrist arm is mainly composed of flat wrist arm, inclined wrist arm, combined load-bearing cable seat, aluminum alloy support, sup...
