Household car door protection plate middle body welding structure

Abstract

The invention discloses a household car door protection plate middle body welding structure. The household car door protection plate middle body welding structure comprises a work platform, telescopicrods are mounted on the bottom of the work platform, a first groove is formed in the upper surface of the work platform, second grooves are formed in two side walls inside the first groove, a third groove is formed in the bottom end in the first groove, an impurity outlet opening is formed in the bottom end of the third groove, and communicates with a collecting box through a telescopic pipe, a shell is mounted on the upper surface of the work platform, mounting bases are fixedly welded to the two sides of one end of the work platform, a motor is mounted on the upper surface of each mountingbase, an output shaft of each motor is connected with a screw through a coupler, and one ends of the screws are rotatably connected with one ends inside the second grooves through bearings. Height adjusting work of the work platform can be facilitated, damage caused by welding slag splashing can be avoided, and welding slag can be conveniently subjected to concentrated collecting treatment.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a mid-body welding structure of a door guard plate of a family car. Background technique [0002] Automobile is a vehicle that can be driven by its own power, and can be driven by motor without the need for rails or electric power. In a broad sense, vehicles with four wheels are generally called automobiles. During the production process of automobiles, welding of the middle body of the door guard is required. [0003] However, in the prior art, the welding work of the middle body of the car door guard plate is not convenient for the height adjustment of the working platform, and the damage caused by splashing of welding slag cannot be avoided, and it is not convenient for centralized collection and processing of the welding slag. [0004] For this reason, we propose a middle-body welding structure for the door guard of a family car to solve the problems existing...
