After the loading is completed, the welding tool 4 can be moved to one side of the first protective member 2, and the welding mechanism 1 performs the welding operation on the workpiece 9 to be welded. At this time, due to the protective effect of the first protective member 2, the sparks and splashing residues generated during the welding process will not cause danger to the operator, effectively ensuring the safety of the production process. Therefore, the welding device provided in this embodiment can solve the technical problem in the prior art that the shared workstation of man and machine makes welding more dangerous.

With such a structural setting, multiple welding workbenches 3 and multiple welding fixtures 4 can work together. When one of the multiple welding fixtures 4 is in the welding position, the welding mechanism 1 performs welding operations on the workpiece 9 to be welded on this welding fixture 4. At the same time, another of the multiple welding fixtures 4 is in the loading and unloading position. The operator can perform loading operations synchronously when the welding mechanism 1 is welding, reducing the waiting time between people and machines, thereby effectively improving the welding efficiency.

With such a structural arrangement, the workpiece to be welded 9 can be limited by the first positioning protrusion 43 and the second positioning protrusion 44, ensuring that the position of the workpiece to be welded 9 is stable and will not be displaced during the welding process, thereby effectively ensuring the welding quality.

The driving rack 332 and the first limit member 361 are installed on the rotating seat 36. The driving rack 332 is also installed on the slider of the linear guide. The driving cylinder 331, the linear guide, and the bearing chamber are installed on the mounting seat 34. At the same time, the push rod of the driving cylinder 331 is connected to the slider of the linear guide through the cylinder bracket. The rotating spindle, the spacer, and the ordinary flat key are assembled and installed on the bearing chamber. After the driving cylinder 331 is ventilated, the cylinder push rod pushes the slider and the driving rack 332 to move in a straight line. The movement of the driving rack 332 drives the driving gear 333 matched with it to rotate. The driving gear 333 drives the rotating seat 36 to rotate through the rotating spindle, the ordinary flat key, and the limit sleeve to transmit the torque to realize the workbench rotation function; the mounting seat 34 is mainly used for the installation and rotation of various components. The first limit piece 361 and the second limit piece 342 are used in combination, and the second limit piece 342 mechanically blocks the rotation of the first limit piece 361 and the rotating seat 36 to accurately control the 180° rotation angle of the workbench; the hydraulic buffer and the buffer bracket mainly play the role of limiting the driving rack 332 when it is about to be in place, so as to avoid mechanical impact and damage to components; the positioning protrusion 363 and the supporting protrusion 362 are used in combination, and mainly play the supporting, positioning and quick-changing functions of the welding fixture. The positioning protrusion 363 and the first positioning part 411 in the welding fixture 4 are gap-matched to realize the positioning and quick-changing functions, and the step surfaces of the supporting protrusion 362 and the positioning protrusion 363 support the welding fixture 4 at four points.

[0085] Specifically, the support frame 31 also includes a roller frame body, an anchor bolt assembly, a tank chain and a tank chain bracket. The roller frame body is used to support the welding workbench 3.

[0086] Specifically, the welding tool 4 also includes an identification plate, which is engraved with parts applicable to the welding tool 4, so that operators can quickly identify multiple sets of fixtures when they are used.

[0087] Specifically, the working process of the welding device is as follows: the operator assembles and fixes the workpiece 9 to be welded on the welding tool 4 of the welding workbench 3 in the operator's working area, and uses the quick-change mechanism to quickly install the welding tool 4 on the welding workbench 3. The operator manually starts the repositioning button of the welding workbench 3, and the welding workbench 3 automatically repositions to the welding area of ​​the welding robot. After the welding robot receives the in-place signal of the welding workbench 3, it automatically welds the workpiece 9 to be welded. After the welding of the workpiece 9 is completed, the welding workbench 3 automatically repositions to the operator's working area, and the operator interchanges the welded parts with the workpiece 9 to be welded, thereby completing a working cycle of one workstation.

[0088] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0089] 1) The dual working area of ​​man and machine is adopted, the manual working area is separated from the welding area, and the manual working environment is improved;

[0090] 2) The equipment has multiple stations. When the welding robot is welding parts at one station, the operator can replace parts and welding fixtures at other stations at the same time, so that people and machines can work at the same time and the welding efficiency is high;

[0091] 3) Multiple stations share one welding robot. When a large number of parts are produced in a multi-station production workshop, fewer robots are needed and the workshop planning cost is also low;

[0092] 4) The welding workbench is rotatable and movable, and the welding fixture can be quickly replaced. The rotating welding workbench can make the front and back of the welded parts face the welding robot, so there is no situation where the weld seam is facing the back of the welding robot, which is difficult to weld, and reduces the welding blind area of ​​the welding robot;

[0093] 5) The welding fixture installed on the welding workbench adopts a one-side two-pin positioning structure, which is accurate in positioning and convenient and quick in replacing the welding fixture;

[0094] 6) The welding tooling as a whole covers the rotating worktable, and the positioning structure is placed at the bottom of the welding fixture tooling. There is no need to frequently clean the welding slag and maintain the equipment, and the equipment can still maintain excellent positioning accuracy.
