Problems solved by technology

Among them, the process of hoisting the frame and turning it over 180° by the driver will easily cause deformation of the welded side of the frame and cause the entire frame to tilt, which will affect the production quality, and the production efficiency of this welding method is low.

Embodiment Construction

[0017] Such as figure 1 and figure 2 As shown, a frame assembly production line of the present invention includes a hydraulic station 1 and a track 2, a mobile trolley 3 is arranged on the track 2, an overturning device controlled by the hydraulic station is provided at one end of the track 2, and a track at the other end of the overturning device 2 There are pressing devices controlled by the hydraulic station 1 on both sides. The overturning device includes four vertical hydraulic cylinders 4 arranged in a rectangular shape, two of which are respectively provided at both ends of the track 2, and a horizontal hydraulic cylinder parallel to the track 2 is provided on the upward vertical piston rod 5 in the vertical hydraulic cylinder 4. Cylinder 6, a fixed plate 8 is arranged between the two horizontal piston rods 7 of the two horizontal hydraulic cylinders 6 at the same end, and the inner sides of the two fixed plates 8 are respectively rotated and connected with an overtur...

Abstract

The invention discloses a frame assembly production line and a use method thereof. The production line comprises a hydraulic station and a rail, wherein the rail is provided with a mobile trolley; one end of the rail is provided with a turning device which is controlled by the hydraulic station; two sides of the rail at the other end of the turning device are respectively provided with a propping device which is controlled by the hydraulic station; the hydraulic station is used for controlling the propping devices and the turning device to fix and turn a crossbeam, a middle support and side supports required to be assembled and welded; and the mobile trolley drives an assembling part on the mobile trolley to move along the rail, thus the fixing effect is good. By using the method provided by the invention, horizontally symmetrical turning is carried out on a frame with one well welded surface, thus the whole frame does not generate deformation due to turning, thereby ensuring the assembly and welding quality of the whole frame, and greatly improving the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of semi-trailer production, and in particular relates to a vehicle frame assembly production line and a use method thereof. 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 vehicle frame is hoisted up and turned over 180° by driving, which easily causes the deformation of the welded one side of the vehicle frame and causes the entire...
