S111 Bodyside Welding Line

S111 bodyside welding line

Project introduction: S111 side wall automatic welding line. Two models, the left and right sides are in line, 30JPH, 26 robots.

As far as each welding line is concerned, it is composed of welding process, transmission device, welding equipment (welding torch, welding robot); as far as the entire automobile body welding line is concerned, it generally includes the body side wall assembly line, body door Cover assembly line, floor assembly line, body welding main line, etc. (there is no absolute summary yet). Each part has corresponding main lines, sub-lines, left and right symmetrical lines and independent islands. According to the different production tempo, degree of automation and production methods, each line is divided into several stations: each station is connected as a whole through a transmission device, and each station is responsible for completing a part of the work.

Automatic production line for single vehicle

The typical form of the production line is shown in Figure 5. It generally uses fixed special fixtures and cooperates with manipulators for automatic welding and assembly. Materials are automatically transported and put in by cranes, and reciprocating shuttle machines are often used for product transportation between each station. It is characterized by high production efficiency, high degree of automation, and stable quality, but it is still a single-species production line.

Analysis of the structure and working principle of the transmission device of the automobile welding production line.

Taking the transmission device of the automobile side panel assembly as an example, its structure and working principle will be analyzed in detail below.

The transmission device of the side panel assembly line of a certain vehicle type adopts a four-station reciprocating rod device, which can realize horizontal and vertical movement. The structure and function of each sub-assembly are analyzed as follows:.

Synchronous rack device and jacking device

Working principle: The cylinder drives the "active gear" in the jacking device to rotate through the "active cylindrical gear bar", thereby driving the "driven cylindrical gear bar" to move, and indirectly pushing the "jacking frame" to move up and down, realizing the horizontal movement to The conversion of the vertical movement achieves the purpose of freely lifting the side panel of the vehicle body. In addition, the part 6 (support guide cylinder) in the synchronous rack device mainly plays the role of guiding and ensuring that the active cylindrical gear bar is always meshed with the driving gear in the jacking device; part 5 (anti-rotation angle iron) mainly plays the role of preventing the active cylindrical gear The role of the gear bar rotation. Part 1 (auxiliary thrust cylinder) in the jacking device mainly plays the role of equalizing vertical motion thrust.
