Semitrailer bottom plate laser welding equipment

Abstract

The invention provides semitrailer bottom plate laser welding equipment. The semitrailer bottom plate laser welding equipment comprises a pair of lathe bed rails and a pair of trolley rails arranged between the lathe bed rails, a logistics trolley used for supporting a semitrailer bottom plate and a semitrailer frame is arranged on the trolley rails in a sliding mode; a pair of walking end beams are arranged on the lathe bed rails in a sliding mode, and a welding gantry beam and a lifting pressing mechanism used for fixing and pressing the semitrailer bottom plate are arranged between the two walking end beams; a welding head system capable of moving horizontally and going up and down is arranged on the welding gantry beam, and a flexible pressing wheel used for pressing the semitrailer bottom plate in a follow-up mode is arranged on the welding head system. According to the semitrailer bottom plate laser welding equipment, the gap between the semitrailer bottom plate and the semitrailer frame is reduced, laser self-fluxing penetration welding is achieved, the semitrailer frame and the bottom plate do not need to be turned over in the welding process, the labor intensity is reduced, and the production safety is improved.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a laser welding equipment for the bottom plate of a semi-trailer. Background technique [0002] In the field of semi-trailer manufacturing, semi-trailer bottom plate welding is a very important and indispensable welding process in semi-trailer production. During welding, the semi-trailer bottom plate needs to be welded above the frame. At present, manual arc welding is used for the welding of the bottom plate and the frame of the semi-trailer. The entire welding process of the bottom plate is done manually. The labor intensity is high, the welding quality is unstable, and the production efficiency is low. It is necessary to increase the number of labor to balance the production speed. And in the manual welding process, since the frame and the bottom plate are welded together on the lower side of the bottom plate, in order to facilitate manual operation, the frame is usually place...

Problems solved by technology

For example, the utility model patent application with the application number CN201921234873 discloses an automatic welding machine for the bottom plate of a semi-trailer. Although this device realizes the automatic welding of the bottom plate of a semi-trailer for scientific research, it does not perform any welding on the bottom plate of the semi-trailer and the frame during the welding process. Pressing and fixing, the automatic welding machine does not match the special pressing mechanism for the bottom plate, so there will be a long distance between the bottom plate and the frame, poor contact, etc., resulting in defects such as inability to perform laser welding or false welding
