[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application discloses an automatic welding device for workpieces. Figure 1-4 , an automatic workpiece welding device, comprising a welding table 1, a linear motor 2, a moving frame 3, a moving component 1 4, a moving component 2 5 and a welding body 6, the top outer wall of the welding table 1 is fixedly connected to two mounting plates 8 through a fixing column 7, the outer walls of the two mounting plates 8 are rotatably connected to a plurality of rotating shafts 9, the plurality of rotating shafts 9 are uniformly distributed on the outer walls of the mounting plates 8 in an equidistant linear array, the outer walls of the plurality of rotating shafts 9 are fixedly connected to conveying rollers 10, and the outer walls of the two mounting plates 8 are installed with clamping mechanisms;

[0021] The clamping mechanism includes a fixed plate 14 fixedly connected to the bottom outer walls of the two mounting plates 8 and two clamping plates 19 arranged above the multiple rotating shafts 9, the bottom outer wall of the fixed plate 14 is fixedly connected to two guide rails 15, the outer walls of the two guide rails 15 are slidably connected to multiple sliders 16, the bottom outer walls of every two sliders 16 are fixedly connected to a movable plate 17, the bottom middle outer walls of the two movable plates 17 are rotatably connected to a connecting rod 22, the bottom middle outer wall of the fixed plate 14 is rotatably connected to a driving arm 21 through a fixed shaft 20, the ends of the two connecting rods 22 away from the movable plate 17 are hinged to the two ends of the driving arm 21, the bottom outer walls of the two movable plates 17 are fixedly connected to a U-shaped frame 18, and the end of the U-shaped frame 18 away from the movable plate 17 is fixedly connected to the clamping plate 19.

[0022] An electric cylinder 23 is fixedly mounted on the bottom outer wall of the fixed plate 14 , and one end of the electric cylinder 23 is fixedly connected to the top outer wall of a movable plate 17 .

[0023] One end of the plurality of rotating shafts 9 passes through the mounting plate 8 and is fixedly connected with a synchronous wheel 11 , and a synchronous belt 12 is mounted on the outer wall of the plurality of synchronous wheels 11 .

[0024] A servo motor 13 is fixedly mounted on the outer wall of a mounting plate 8 away from the multiple synchronous wheels 11 . The end of the output shaft of the servo motor 13 passes through the mounting plate 8 and is fixedly connected to one end of one of the rotating shafts 9 .

[0025] The top outer wall of the welding table 1 is installed with a first conveyor belt 24 and a second conveyor belt 25. The first conveyor belt 24 is located directly in front of the welding table 1 and is higher than the upper surface of multiple conveyor rollers 10. The second conveyor belt 25 is located directly behind the welding table 1 and is lower than the lower surface of multiple conveyor rollers 10.

[0026] The implementation principle of the workpiece automatic welding device of the embodiment of the present application is as follows: in actual use, the workpiece is placed on the first conveyor belt 24, and the first conveyor belt 24 conveys the workpiece to the surface of the plurality of conveyor rollers 10. When the workpiece is located on the plurality of conveyor rollers 10, refer to Figure 3 , start the servo motor 13, the output shaft of the servo motor 13 drives a rotating shaft 9 to rotate, and then a synchronous wheel 11 rotates. At this time, the multiple synchronous wheels 11 can rotate synchronously through the cooperation of multiple synchronous belts 12, so that the multiple rotating shafts 9 drive the multiple conveying rollers 10 to rotate. When the multiple conveying rollers 10 rotate, they can drive the workpiece to move until the workpiece moves to the middle section of the mounting plate 8, and then turn off the servo motor 13, and the workpiece stops moving;

[0027] Through the cooperation of the clamping mechanism, refer to Figure 4 , start the electric cylinder 23. When the output shaft of the electric cylinder 23 contracts, it drives a movable plate 17 to move inward. A movable plate 17 squeezes a connecting rod 22 inward, and the connecting rod 22 rotates. A connecting rod 22 pushes the driving arm 21 inward to rotate around the fixed shaft 20. At this time, when the fixed shaft 20 rotates, its other end pulls another connecting rod 22 inward to move. The other connecting rod 22 pulls another movable plate 17 inward while rotating. At this time, the two movable plates 17 slide relatively close to each other synchronously, and then the two clamping plates 19 are pulled relatively close to each other through multiple U-shaped frames 18 to clamp the workpiece;

[0028] After the workpiece is fixed, refer to Figure 1 and Figure 2 The linear motor 2 can drive the moving frame 3 to move forward and backward, thereby adjusting the front and rear position of the welding body 6. The moving component 1 4 can drive the moving component 2 5 to move left and right, thereby adjusting the left and right position of the welding body 6. The moving component 2 5 can drive the welding body 6 to move up and down, thereby adjusting the height of the welding body 6, thereby realizing flexible adjustment of the welding position, and the welding body 6 can weld the workpiece;

[0029] After welding is completed, the welding body 6 is driven to move and reset through the cooperation of the linear motor 2, the moving frame 3, the moving component 1 4 and the moving component 2 5. At this time, the electric cylinder 23 in the clamping mechanism is started, and the output end of the electric cylinder 23 is extended, so as to push a moving plate 17 to move outward. Similarly, the other moving plate 17 moves outward synchronously. When the two moving plates 17 move away from each other, the two clamping plates 19 are driven away from each other through the multiple U-shaped frames 18 to release the fixation of the workpiece. The servo motor 13 is started to continue to drive the multiple conveying rollers 10 to rotate through the cooperation of the multiple synchronous wheels 11 and the synchronous belt 12, so as to move the workpiece to the surface of the second conveyor belt 25, and the second conveyor belt 25 can convey the workpiece out.
