[0002] When the split end wall is assembled, the bottom of the end wall cover plate and the outer plate of the end wall are not on the same plane. During welding, pads must be added to ensure the flatness of the outer plate of the end wall. During welding, due to the lack of effective positioning , the entire end wall is in a movable state, and the deformation after welding is relatively large. It takes a series of repairs to make the flatness of the outer plate of the end wall meet the requirements. However, the repair process is not only time-consuming and laborious, but also has a high repair rate. It is easy to cause quality problems

Embodiment Construction
[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0033] Such as Figure 1 to Figure 5 As shown, a split-type end wall anti-deformation control assembly welding method includes the following steps:
[0034] Step 1, assembling and welding the end wall cover plate 1;
[0035] Step 2, connecting the outer panel 2 of the end wall to the outer side of the cover plate 1 of the end wall with bolts to form an assembled structure;
[0036] Step 3, assemble and weld the end wall exoskeleton 3 on the end wall installation platform 4, and then put the assembled structure in step 2 into the end wall exoskeleton 3 for reverse assembly;
[0037] Step 4: At least press the outer frame 3 of the end wall on the installation platform 4 of the end wall, make the outer panel 2 of the end wall fit the upper surface of the installation platform 4 of the end wall, and at the same time embed ...

The invention relates to a split-type end wall anti-deformation control assembly welding method, comprising the following steps: step 1, assembling and welding the end wall cover plate; step 2, connecting the end wall outer plate to the end wall cover plate with bolts On the outside, an assembled structure is formed; Step 3, assemble and weld the outer frame of the end wall on the end wall installation platform, and then put the assembled structure in step 2 into the outer frame of the end wall for reverse assembly; Step 4, at least put the end wall The outer frame is pressed tightly on the end wall installation platform, so that the end wall outer plate is attached to the upper surface of the end wall installation platform, and at the same time, the bottom of the end wall cover plate is embedded into the central opening of the end wall installation platform to form a positioning fit; Step 5. Weld the outer panel of the end wall and the outer frame of the end wall together in the manner of welding from the center to both sides. The invention can effectively control the deformation of the end wall after welding and reduce the maintenance work.
Description
technical field [0001] The invention relates to a car body welding method, in particular to a split-type end wall anti-deformation control assembly welding method. Background technique [0002] When the split end wall is assembled, the bottom of the end wall cover plate and the outer plate of the end wall are not on the same plane. During welding, pads must be added to ensure the flatness of the outer plate of the end wall. During welding, due to the lack of effective positioning , the entire end wall is in a movable state, and the deformation after welding is relatively large. It takes a series of repairs to make the flatness of the outer plate of the end wall meet the requirements. However, the repair process is not only time-consuming and laborious, but also has a high repair rate. It is easy to bring quality risks. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The purpose of the present invention is to overcome the de...
