Problems solved by technology

[0003] However, in the existing automatic welding system, there are large investment, single application variety, low efficiency of robots in the automatic welding system, and long flexible switching time of the production line, resulting in low welding efficiency. There are many unstable factors
[0004] At present, flexible welding and welding production lines at home and abroad are basically used in large-scale vehicle production lines to meet the flexible production of two or three models. The main method is to dynamically identify the models and then replace the corresponding tooling to realize the positioning welding of different models. It is a large-scale complete vehicle with a relatively large volume, and generally adopts an assembly line single-line production mode, which takes up a relatively large space

Abstract

The invention discloses a flexible welding system capable of horizontally rotating and shifting car models. The flexible welding system comprises one or more welding robots, wherein a welding work table for allowing work pieces to be placed is arranged on one sides of the welding robots; a guard fence is arranged around the welding robots and the welding work table, and a manual piece taking and placing opening is formed in the guard fence, manual guardrails, a safety light curtain, a foot light curtain and an operation panel are arranged at the manual piece taking and placing opening; a robot control cabinet and a welding work table control cabinet are arranged on the outer side of the guard fence; the welding robots are connected with the robot control cabinet; the welding work table is connected with the welding work table control cabinet; and a welding clamp set comprises a horizontal rotating clamp set and a fixing clamp set. According to the flexible welding system disclosed by the invention, the applying deficiency of intelligent robots in the field of manufacturing of automobiles is sufficiently considered; the work table capable of horizontally rotating and shifting the car models is allocated for the robots, so that under the premise that the reforming degree of a robot welding system is minimum, multi-car-model flexible production is realized; and the flexible welding system is low in occupied area, high in production efficiency, high in automation degree and good in compatibility, can be matched with other automated production equipment for use, and can be greatly applied in the layout situation with large horizontal space.

Example Embodiment

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0019] Such as figure 1 , 2 As shown, the horizontally rotating vehicle switching flexible welding system includes a welding robot (not shown in the figure). The welding robot is installed and fixed by the robot stand 1, and a welding table 2 for placing the workpiece is provided on one side of the welding robot. There is a safety fence 3 around the welding robot and welding workbench 2, the corresponding safety fence 3 on the other side of the welding workbench 2 is equipped with a manual pick-and-place part 4, and the manual pick-and-place part 4 is equipped with a manual guardrail (not shown in the figure) Out), safety grating 5, foot grating 6, operation panel 7. The outer side of the safety fence 3 is provided with a robot control cabinet 8 and a welding workbench control cabinet 9; the welding robot is connected with the robot control cabinet 8; the welding workbench 2 is connected with the welding workbench control cabinet 9.
[0020] In order to improve production efficiency, each welding system can be equipped with multiple welding robots for simultaneous welding operations.
[0021] The welding workbench 2 includes a rectangular base 201, which is installed on the ground through an adjusting device 202; a welding fixture group 203 is installed above the rectangular base 201, and the welding fixture group 203 includes a horizontal rotating fixture group 2031 installed at one end of the rectangular base 201 , A fixed clamp set 2032 installed on the other end of the rectangular base 201.
[0022] The horizontal rotating fixture group 2031 includes a circular base 201311 installed on the upper surface of the rectangular base 201, the circular base 201311 is provided with a servo motor (not shown in the figure), and a coaxially arranged support is connected above the circular base 201311 Column 201312, the support column 201312 is driven by a servo motor to rotate relative to the circular base 201311. The top of the support column 201312 is equipped with a multi-faceted mounting plate 201313. The multi-faceted mounting plate 201313 includes 4 sides. A total of 4 sets of switching fixtures 201314 can be installed. Realize the clamping of four different workpieces. The multi-sided mounting board 201313 can be designed into any number of surfaces, and each surface can be the same or different in size to install different switching fixtures 201314.
[0023] The switching fixture 201314 includes a flange connecting plate 201315 connected to a multi-faceted mounting plate 201313, a workpiece clamping jaw 201316 is installed on the flange connecting plate 201315, and the workpiece clamping jaw 201316 is driven by a jaw cylinder 201317; the horizontal rotating fixture group 2031 An angle detection switch 201318 is also provided, and the angle detection switch 201318 is installed on the support column 201312.
