Problems solved by technology

During overhead welding, the staff is working with their heads up for a long time, and the physical exertion is serious, especially the welding slag and smoke falling during overhead welding will cause serious interference to the staff, and they cannot continue to work, especially when welding long weld seams. The seams are intermittent and the quality of the frame cannot be guaranteed

Abstract

The invention relates to an auxiliary welding turnover machine for a semitrailer frame. The auxiliary welding turnover machine comprises a driving turnover table, a driven turnover table and a turnover device, wherein the driving turnover table and the driven turnover table are symmetrically arranged, and the turnover device is arranged on the driving turnover table and the driven turnover table.The turnover device comprises bearing pedestals symmetrically arranged on the driving turnover table and the driven turnover table, rotating shafts arranged on the bearing pedestals, rotating arms fixed to one ends of the rotating shafts and clamping devices arranged on the rotating arms. The driving turnover table is provided with a rotating device, the rotating device comprises a driven wheel arranged on the rotating shaft on the driving turnover table, a power device arranged on the driving turnover table and a driving wheel arranged on an output shaft of the power device, and the driven wheel is engaged with the driving wheel. The auxiliary welding turnover machine is used for welding of the semitrailer frame, workers is in a standing state in the welding process, the sight line is good, interference is small, moving is convenient, and the welding speed and welding quality can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of semi-trailer frame welding, in particular to an auxiliary welding turning machine for a semi-trailer frame. Background technique [0002] A semi-trailer is a trailer whose axle is positioned behind the vehicle's center of gravity (when the vehicle is evenly loaded) and is fitted with a hitch that transmits horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, and their types are divided into 11-meter warehouse semi-trailers, 13-meter warehouse semi-trailers, and low-bed semi-trailers. It is a heavy-duty transport vehicle connected to the semi-trailer head through the traction pin. [0003] The frame is the most important load-bearing part in the semi-trailer, which plays an important role in the car. The side beam frame and the center beam frame of the car all contain the frame. The frame is usually made of low-alloy steel plate stamped, and the cross-secti...
