DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 5 As shown, a switch cabinet frame welding device described in an embodiment of the present invention includes a processing table 1, two symmetrically arranged support frames 3 are fixed on one side of the top of the processing table 1, a screw rod 33 is arranged inside the support frame 3, a second motor 331 is arranged on the top of the support frame 3, the shaft end of the second motor 331 is fixedly connected to the screw rod 33, the external thread of the screw rod 33 is connected to a lifting block 332, a welding manipulator 2 is arranged on one end of the lifting block 332, a steering wheel 4 is arranged on the side of the support frame 3 close to the welding manipulator 2, the bottom end of the steering wheel 4 is rotatably connected to the top of the processing table 1, a steering motor 41 is installed on the top of the processing table 1, the shaft end of the steering motor 41 is fixedly connected to the bottom end of the steering wheel 4, a support frame 42 is fixed on the outside of the steering wheel 4, a support column 43 is fixed on the top of the steering wheel 4, and three connecting plates 45 are fixed on the outside of the support column 43 at equal intervals;

[0034] When welding the switch cabinet frame, it is necessary to weld the metal parts required for welding together. At this time, the metal parts are installed, and the grooved metal plate is fixed on the four sides of the connecting plate 45, and then the metal square tube is fixed on the top of the support frame 42. At this time, the grooved metal plate and the end of the metal square tube are fitted together, and then the welding manipulator 2 is started to weld the connection between the grooved metal plate and the metal square tube. However, the range of movement of the welding manipulator 2 is small, and the welding manipulator 2 is set to weld only the connection in the current direction. After the welding of the connection at the current height is completed, the position of the welding manipulator 2 needs to be moved. At this time, the second motor 331 is started to drive the screw rod 33 to rotate, and the screw rod 33 drives the lifting block 332 to move upward. At this time, the lifting block 332 drives the welding manipulator 2 to move. When the welding manipulator 2 moves to the welding When the steering wheel 4 is rotated, the distance between the two welding manipulators 2 is adjusted by the support frame 3, and then the distance between the welding manipulator 2 and the steering wheel 4 is adjusted. Due to the different lengths and widths of the switch cabinet frame, the position of the welding manipulator 2 is not convenient for welding the connection. Adjusting in this way can ensure that the connection between the welding manipulator 2 and the metal part is at the same distance and position, which is more convenient for welding. After the welding is completed, the frame can be removed from above the steering wheel 4.

[0035] like Figures 1 to 6 As shown, two groups of symmetrically arranged support arms 451 are fixed to the outer side of the connecting plate 45, and the lengths of the two groups of support arms 451 are different;

[0036] By providing support arms 451 of different lengths, it is easier to fix metal pieces of different lengths, thereby facilitating welding of metal pieces.

[0037] like Figures 1 to 3 As shown, a first motor 31 is arranged between the two support frames 3, the first motor 31 is installed on the top of the processing table 1, a rotating rod 32 is arranged on one side of the first motor 31, teeth are fixed on the outer side of the rotating rod 32, an output gear is fixed on the end of the rotating shaft of the first motor 31, the output gear is meshed and connected with the teeth of the rotating rod 32, a slide groove is provided at the top and bottom ends of the support frame 3, both ends of the rotating rod 32 are penetrated in the slide groove of the support frame 3, a slider is fixed at the top and bottom ends of the guide rod 333, the slider is slidably connected in the slide groove of the support frame 3, the rotating rod 32 is threadedly connected with the two sliders below, and the screw rod 33 is rotatably connected with the slider;

[0038] When adjusting the distance between the welding manipulators 2, start the first motor 31 to rotate and drive the rotating rod 32 to rotate. At this time, the rotating rod 32 drives the sliders under the two support frames 3 to move through the threads at both ends. At this time, the slider slides inside the slide groove of the support frame 3. When the slider slides, it drives the screw rod 33 and the guide rod 333 to move. At this time, it can also drive the lifting block 332 to move. The lifting block 332 drives the welding manipulator 2 to move and adjust the distance between them. In this way, the position of the welding manipulator 2 can be adjusted, and the position of the welding manipulator 2 can be made more convenient for welding.

[0039] like Figures 1 to 4 As shown, a moving platform 21 is fixed to the bottom end of the welding robot 2, and a guide sleeve 335 is provided at one end of the moving platform 21 close to the lifting block 332. The guide sleeve 335 is fixedly connected to the lifting block 332, and the moving platform 21 is inserted into the inside of the guide sleeve 335;

[0040] When the steering wheel 4 rotates, due to the inconsistency of the length, width and length of the cabinet frame, the welding robot 2 will block the cabinet frame when the steering wheel 4 drives the cabinet frame to rotate. Therefore, a moving platform 21 is provided. When the steering wheel 4 rotates, the moving platform 21 can move inside the guide sleeve 335. During the movement of the moving platform 21, the distance between the welding robot 2 and the cabinet frame can be controlled, thereby preventing the welding robot 2 from blocking the steering wheel 4 from driving the cabinet frame to rotate.

[0041] like Figures 1 to 5 As shown, a push rod 211 is fixed to the bottom end of the moving platform 21 near one end of the guide sleeve 335, and a push plate 212 is slidably connected between the two push rods 211. The end of the push plate 212 away from the push rod 211 is close to the outer side of the steering wheel 4, and convex plates 44 are fixed on both sides of the steering wheel 4 near the longer support arm 451;

[0042] When the steering wheel 4 rotates, the convex plate 44 will be driven to rotate. The two convex plates 44 and the two longer support arms 451 are on the same side. When rotating to the side of the longer support arms 451, the distance between the welding robot 2 and the cabinet frame needs to be farther. Therefore, when the steering wheel 4 drives the convex plate 44 to rotate, the convex plate 44 will push the push plate 212 to move. At this time, the push plate 212 drives the moving platform 21 to retract into the inside of the guide sleeve 335 through the push rod 211. At this time, the moving platform 21 drives the welding robot 2 away from the steering wheel 4, and the distance between the welding robot 2 and the cabinet frame can be automatically adjusted.

[0043] like Figures 1 to 5 As shown, a limiting column 421 is fixed at the top of the support frame 42;

[0044] When fixing, the metal square tube is inserted into the outside of the limiting column 421, and the limiting column 421 can limit and fix the metal square tube.

[0045] like Figures 6 to 8 As shown, a clamping frame 452 is hingedly connected to one end of the support arm 451 away from the connecting plate 45, a flip pressing plate 47 is hingedly connected to the top of the clamping frame 452, a third motor 471 is installed on the top of the flip pressing plate 47, a turntable 472 is rotatably connected inside the flip pressing plate 47, a rotating shaft end of the third motor 471 is rotatably connected to the turntable 472, a roller is rotatably connected to one side of the clamping frame 452 away from the turntable 472, and distance sensors 478 are installed on both sides of the clamping frame 452;

[0046] When fixing the grooved metal plate, flip the flip pressure plate 47 so that it is in a vertical state with the clamping frame 452, then place the grooved metal plate inside the clamping frame 452, then rotate the flip pressure plate 47 to press on the inside of the grooved metal plate, then start the third motor 471 to drive the turntable 472 to rotate, and the turntable 472 drives the grooved metal plate to move to both sides. When the grooved metal plate moves to the end, the distance sensor 478 will detect it. By detecting the two ends and converting the number of revolutions of the turntable 472 into length, the length of the grooved metal plate can be detected at this time. When the grooved metal plate is too long or too short, the staff can be reminded to replace it to prevent the length from affecting subsequent welding. When the length of the grooved metal plate reaches the standard, the turntable 472 can drive the grooved metal frame to move to the center position, which is more convenient for welding.

[0047] like Figure 8 As shown, a pressing block 453 is arranged below the rotating disk 472, and the pressing block 453 is slidably connected to the inside of the clamping frame 452, and the top of the pressing block 453 is rotatably connected to a rotating wheel, and a push column 454 is arranged on the side of the pressing block 453 close to the supporting arm 451, and slopes are provided on both sides of the push column 454, and second springs 455 are fixed on both sides of the push column 454, and the other end of the second spring 455 is fixedly connected to the clamping frame 452, and a first card slot 456 is arranged on one end of the supporting arm 451 close to the push column 454, and the first card slot 456 can be engaged with the push column 454;

[0048] When the welded cabinet frame is removed, the clamping frame 452 will be blocked, so the clamping frame 452 and the support arm 451 are set to be hinged, and the clamping frame 452 can be flipped when the cabinet frame is removed. During the welding process, in order to ensure that the clamping frame 452 is in a stable state, it is necessary to fix it between the support arm 451. Therefore, when the grooved metal plate is placed into the interior of the clamping frame 452, the pressure block 453 will be squeezed downward. At this time, the pressure block 453 will be pushed toward the direction of the support arm 451 along the slope of the push column 454. At this time, the push column 454 is inserted into the interior of the first card slot 456, which can fix the support arm 451 and the clamping frame 452. When the grooved metal plate is removed from the interior of the clamping frame 452, the second spring 455 can pull the push column 454 out from the interior of the first card slot 456, and at the same time, the push column 454 pushes the pressure block 453 upward to restore the original position, so that the cabinet frame can be easily removed.

[0049] like Figures 8 to 9 As shown, a movable groove is provided inside the clamping frame 452, and a clamping block 475 is provided inside the movable groove. A second clamping groove 474 is provided on the side of the flip pressing plate 47 close to the clamping block 475, and the clamping block 475 can be engaged with the second clamping groove 474. A push frame 477 is fixed on the side of the clamping block 475 away from the flip pressing plate 47. The top and bottom ends of the push frame 477 are fixed with a third spring 476, and the other end of the third spring 476 is fixedly connected to the clamping frame 452.

[0050] During the clamping process, the clamping frame 452 needs to fix the grooved metal plate, so at this time the block 475 will be inserted into the inside of the second groove 474, and the flip pressure plate 47 can be fixed at this time, and the grooved metal plate can be limited. When the grooved metal plate needs to be removed, the elastic force of the third spring 476 pushes the push frame 477, and the push frame 477 drives the block 475 to move out from the inside of the second groove 474, so that the flip pressure plate 47 can be flipped.

[0051] like Figures 5 to 10 As shown, a telescopic rod 473 is slidably connected inside the support arm 451, a rotating ring 461 is provided above the connecting plate 45, a guide groove 465 is provided below the rotating ring 461, a sliding column is provided at one end of the telescopic rod 473 close to the rotating ring 461, and the sliding column is slidably connected inside the guide groove 465, a tooth is fixed on one side of the rotating ring 461, a transmission rod 46 is provided on one side of the rotating ring 461, the transmission rod 46 is meshed and connected with the teeth of the three rotating rings 461, the transmission rod 46 is rotatably connected with the three connecting plates 45, one side of the transmission rod 46 is meshed and connected with a transmission gear 462, a rotating frame 463 is inserted at the top of the transmission gear 462, a fixing hole 464 is provided at the top of the lowest connecting plate 45, and the rotating frame 463 can be inserted inside the fixing hole 464;

[0052] When it is necessary to insert the card block 475 into the interior of the second card slot 474, the rotating rotating frame 463 drives the transmission gear 462 to rotate, and the transmission gear 462 drives the transmission rod 46 to rotate, and the transmission rod 46 simultaneously drives the three rotating rings 461 to rotate. At this time, the rotating ring 461 drives the guide groove 465 to rotate, and the guide groove 465 can drive the sliding column of the telescopic rod 473 to move, and the sliding column pushes the telescopic rod 473, and the telescopic rod 473 pushes the pushing frame 477 to drive the card block 475 into the interior of the second card slot 474. At this time, multiple flip pressure plates 47 can be fixed at the same time, and then the rotated rotating frame 463 is inserted into the interior of the fixing hole 464 to complete the fixation. When it is necessary to release the fixation, the rotating frame 463 is pulled out from the interior of the fixing hole 464 and the rotating frame 463 is rotated in the opposite direction to make the telescopic rod 473 move in the opposite direction, so that multiple flip pressure plates 47 can be fixed and released at the same time.
