Abstract

The invention discloses an overall assembly tool for passenger car body large pieces. The overall assembly tool comprises a side wall tool, a body structure, a front wall tool and a rear wall tool, wherein the body structure comprises a side wall frame, a front wall frame, a rear wall frame and a top frame; the side wall tool comprises a first hydraulic base, a first hydraulic device and a first tool base; one end of the first hydraulic base is articulated with one end of the first tool base; the other end of the first hydraulic base is connected with the other end of the first tool base through the hydraulic device; and the first tool base is a rectangular frame matched with the side wall frame of the body structure. In the tool disclosed by the invention, single piece welding and overall assembly welding of a passenger car are integrated; by starting a hydraulic control system and lifting the front wall, rear wall and side wall tools, the front and rear side single pieces of the body are welded; then the body is covered by a top cover to finish the overall assembly of the body; and thus, the precision can be effectively guaranteed, and the tool efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical tooling, and in particular relates to a tooling for assembly of large pieces of passenger car bodies. Background technique [0002] The quality of the bus frame directly determines the quality of the bus. The skeleton production of the bus industry follows the process of producing five large pieces first, and then transferring the five large pieces to assemble them on the general assembly tooling. It is difficult to guarantee the accuracy of the skeleton after the assembly. In the production of passenger cars in the industry, the front, rear, left side, right side, and roof of the body have corresponding fixtures, referred to as five large pieces of tooling. The five large films are the front wall, the rear wall, the side wall (left and right), and the top wall of the bus. After each large piece is completed, five large pieces are combined on the general assembly tool to form the skeleton of ...
