Flexible bodyside welding system
1. Process introduction:
The flexible system of the side wall welding line mainly completes
the assembly and welding work of the side wall inner panel and
outer panel assembly. It can realize the flexible switching of 4
types of vehicle types. Using core technologies such as turntable
and hub, cross slide, and split switching system, it can realize
collinear welding of the left/right sides of various different
body-in-white, and can achieve a production cycle of 60JPH and
automation. The rate is as high as more than 90%.

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.
In the initial stage of automobile development, straight-through
production lines (simplified through-type production lines) were
mainly used. In the 1960s and 1970s, accompanying fixture
production lines were used more often, but due to the large size,
complex structure and large motion inertia of the accompanying
fixtures , It is difficult to realize the shortcomings of
multi-variety production and the supporting use of robots.
Therefore, in the middle and late 1970s, major automobile
manufacturers improved the through-type production lines. The
through-type production line means that the positioning and
clamping device (fixture) of the workpiece is separated from the
transmission device between the stations. Lifting support rod
reciprocating welding line is a commonly used through-type
production line. This production line mainly includes the following
parts: workpiece clamping and positioning system, transmission
device between stations and conveying rod lifting system.
