Front and rear cover on-line spreader of high-top twin truck cab

Abstract

The present invention discloses a front and rear cover on-line spreader of high-top twin truck cab, including a spreader frame and spreader up and down positioning mechanisms mounted on the spreader frame, front and rear cover positioning mechanisms, a bottom surface supporting mechanism of front and rear cover and a rear side supporting mechanism of rear cover: the spreader up positioning mechanism positions between the spreader frame and the hoist; the spreader down positioning mechanism positions between the spreader frame and the pre-installed fixture; the front cover positioning mechanism positions between the front cover and the spreader frame; the rear cover positioning mechanism positions between the rear cover and the spreader frame; the bottom surface supporting mechanism of front cover supports the front cover in lifting; the bottom surface supporting mechanism of rear cover supports the rear cover in lifting; the rear side supporting mechanism of rear cover supports the rear cover in lifting. According the invention, the positioning and supporting mechanisms of the front and rear cover are reasonably disposed so that the workpiece could be conveniently grabbed on-line for lifting, improving the assembly efficiency of high-top twin truck cab, ensuring the assembly quality of products.

Description

technical field [0001] The invention relates to the automobile hoisting and assembly technology, in particular to a lifting device for the front and rear top covers of the cab of a high-roofed double-sleeper truck. Background technique [0002] At present, the typical heavy-duty truck cabs at home and abroad (such as Dongfeng D310, D760) have three types: standard type, extended type, and high-roof double-sleeping type. The high-roof double-sleeping type adopts front roof assembly, middle roof assembly, Rear top cover assembly, left side wall assembly, right side wall assembly and rear wall assembly (hereinafter referred to as front top cover, middle top cover, rear top cover, left side wall, right side wall and rear wall respectively) Sub-block on-line tailor welding process, the assembly sequence is: floor → left and right sides → rear wall → front and rear roof → middle roof → left and right doors. [0003] As far as the front top cover and the rear top cover are concern...

AI Technical Summary

Problems solved by technology

The front and rear roofs of this high-roof double-bedroom cab have great difficulties in getting on the line, for example:

[0004] (1) The front and rear top covers are bulky, difficult to carry manually, and easily deformed;

[0005] (2) When the front top cover falls at a vertical angle, it will interfere with the left and right sides;

[0006] (3) When the rear top cover is falling, it collides with the upper reinforcement beam of the rear wall, and cannot fall into the exact position;

[0007] (4) The rear wall of the rear top cover itself has deformation problems, interferes with the left and right sides, and cannot fall vertically

[0008] Due to the inconvenient lifting of the front and rear roof covers, which affects the assembly efficiency and quality of the cab, it is necessary to design a front and rear roof lifting device with a reasonable structure according to the characteristics of the front and rear roof covers of the high-roof double-bedroom cab.
