Abstract

The invention discloses a frame turning device which comprises a hydraulic station and four vertical hydraulic cylinders which are arranged in a rectangle, wherein a horizontal hydraulic cylinder which is parallel with a track is arranged on an upward vertical piston rod in each vertical hydraulic cylinder; a fixed plate is respectively arranged between two horizontal piston rods of two horizontal hydraulic cylinders at the same end; the inner side of each of the two fixed plates is respectively connected with a turning frame in a rotating mode; a motor for controlling the rotation of the turning frame is arranged at the outer side of one fixed plate; and each vertical hydraulic cylinder and each horizontal hydraulic cylinder are respectively connected with the hydraulic station through hydraulic oil pipes. In the invention, the frame at one side is already welded by adopting a horizontal and symmetrical turning method, so that the whole frame can not be deformed because of turning, the assembling and welding quality of the whole frame is ensured, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of semi-trailer production, in particular to a vehicle frame overturning device. Background technique [0002] The frame of the semi-trailer mainly includes two parallel girders, a middle brace between the two girders, a side brace outside the two girders, and a suspension at the lower part of the two girders. The connection between the above components is welded. At present, there is no assembly line for producing this kind of vehicle frame. The existing production method is: after welding the upper surfaces of each component on the ground, use a crane to lift the vehicle frame and turn it over 180°, with the original lower surface facing upwards. Then weld the suspension on this surface. Wherein the process of hoisting the vehicle frame and turning it over 180° by driving is easy to cause deformation of the vehicle frame on one side that has been welded and cause the entire vehicle frame to tilt, whic...
