Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of automated equipment manufacturing, and in particular relates to an arc welding station for vehicle doors of multiple vehicle models. Background Art
[0002] The current mainstream car door welding station solutions are divided into two types:
[0003] The first solution is to use a gripper to grab the car door, then move the car door to the position where arc welding is required, and move it to a fixed arc welding gun. The robot receives the signal and starts arc welding. The robot model used in this solution must be a robot of more than 210KG, and the gripper has a heavy load. In the first phase, a quick-change plate on the robot side and the gripper side must be made (this solution requires the use of a manipulator. To add a new model, it is necessary to add a gripper bracket and gripper. It is also necessary to add a gripper side gun change plate, which occupies a large area)
[0004] The second solution is to place the car door on the arc welding table and use a robot for arc welding, which has the advantages of stable positioning, small footprint, and easy operation. For robot welding, a robot weighing less than 20KG can be selected, and the arc welding gun has a small load (this solution has cost advantages. When adding new models, the arc welding table needs to be modified to make it compatible with the new models)
[0005] At present, the second solution has obvious advantages, but when importing car models, the old arc welding station needs to be modified, which has a great impact on the production of car doors of old models. On this basis, we have developed an arc welding station with switching function, and the import of car models has no effect on the old models.

The principle is the same as above.
[0044] Working principle:
[0045] first
[0046] According to the vehicle model planning, determine the location of the plug-in port.
[0047] For the current model, six plug-in ports (05, 11, 12, 13, 14, 15) can meet the positioning requirements. You can also adjust the position and quantity according to your own model requirements. Both the position and quantity can be changed.
[0048] Secondly
[0049] Determine the support position on the plug-in block according to the door structure.
[0050] The 0.7mm steel plate at the bottom of the current vehicle model is relatively weak, so the upper frame of the door area and the outer panel support plug-in block 4, the door area side guide and outer panel support plug-in block 5, the door area lower outer panel support plug-in block 6, the door area side guide and outer panel support plug-in block 7, the upper frame of the door area and the outer panel support plug-in block 8 are all equipped with large high-strength rubber blocks to increase the contact area and reduce deformation.
[0051] The upper part of the current vehicle model is a very strong frame, so fewer support blocks are set in the door area upper frame support plug-in block 3, the door area upper frame and outer panel support plug-in block 4, the door area side guide and outer panel support plug-in block 5, and the door area upper frame and outer panel support plug-in block 8. Among them, the door area upper frame and outer panel support plug-in block 4 and the door area upper frame and outer panel support plug-in block 8 include both the upper support and the lower support, and ensure the support stability and optimize the plug-in block structure.
[0052] at last
[0053] According to the arc welding position of the car door, determine the clamping position on the plug-in block.
[0054] The main arc welding of the current model is concentrated on the upper frame and inner panel pressing plug plate 12, the upper frame and inner panel pressing plug plate 10 of the door area, so the plug-in block here is equipped with multiple pressing blocks. The auxiliary positioning is the upper frame pressing plug plate 9 of the door area, the lower part of the door area pressing plug plate 11, and there are fewer positioning blocks.
[0055] Working process: Fig.10 As shown,
[0056] first step
[0057] Six groups of support and plug-in blocks: door area upper frame support and plug-in block 3, door area upper frame and outer panel support and plug-in block 4, door area side guide and outer panel support and plug-in block 5, door area lower outer panel support and plug-in block 6, door area side guide and outer panel support and plug-in block 7, door area upper frame and outer panel support and plug-in block 8 are pre-installed on the plug-in port respectively.
[0058] The four groups of compression plug-in blocks; the door area upper frame compression plug-in block 9, the door area upper frame and inner plate compression plug-in block 10, the door area lower compression plug-in block 11 and the upper frame and inner plate compression plug-in block 12 are pre-installed on the corresponding plug-in ports.
[0059] Step 2
[0060] Move the hand-operated valve and all plug-in blocks are clamped.
[0061] Step 3
[0062] The corresponding vehicle door is put in, and the proximity switches on the door area side guide and the outer panel support plug-in block 5, the door area upper frame and the outer panel support plug-in block 8 are detected to be in place.
[0063] Step 4
[0064] The first clamping mechanism 13, the second clamping mechanism 15, the third clamping mechanism 17, and the fourth clamping mechanism 18 are automatically clamped
[0065] Step 5
[0066] The arc welding robot comes over to perform arc welding and sends a completion signal.
[0067] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
