The invention discloses a flat cantilever and oblique cantilever combining method for a contact net. The method comprises the following steps: grabbing a double-lug bushing through a double-lug bushing manipulator; grabbing an oblique cantilever pipe into the upper bushing of the double-lug bushing through a first oblique cantilever manipulator and a second oblique cantilever manipulator; grabbingthe oblique cantilever again through the first oblique cantilever manipulator and the second oblique cantilever manipulator to the positions at two ends of the double-lug bushing, and moving the oblique cantilever and the double-lug bushing to the position right below a combining and guiding positioning mechanism of the double-lug bushing; raising the oblique cantilever through the second obliquecantilever manipulator; supporting and fixing the lower bushing of the double-lug bushing through the combining and guiding positioning mechanism; threading the flat cantilever into the lower bushingof the double-lug bushing through the first oblique cantilever manipulator and the second oblique cantilever manipulator; and fastening screws on the double-lug bushing through a combining and fastening mechanism to obtain a cantilever product. The method disclosed by the invention achieves full-automatic combination of the flat and oblique cantilevers, so that the production efficiency is improved greatly.
Description
technical field [0001] The invention relates to the field of automatic production of arms, in particular to a method for merging flat arms and inclined arms of catenary. Background technique [0002] The high-speed railway catenary arm includes a flat arm and an oblique arm. To realize the installation of the arm, the flat arm and the oblique arm must first be combined. At present, the pre-fitting of the flat arm and the oblique arm is mainly done manually. Firstly, draw the line on the flat wrist-arm tube and the oblique wrist-arm tube; secondly, cut off the wrist-arm tube according to the marking position; thirdly, install it on the bracket by the staff, and pass the flat wrist arm to the double-ear sleeve connector The lower sleeve in the middle, the slanted wrist arm passes through the upper sleeve in the double-ear sleeve connector, and the main nut and back nut are manually tightened. In actual situations, when installing the flat wrist arm and the inclined wrist arm...
