[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a submerged arc welding bracket, including a base plate 1. The surface of the base plate 1 is provided with two sets of guide grooves. A slider 2 is slidably connected to the inner wall of the guide groove of the base plate 1. A rotating rod 7 is rotatably connected to the left side of the top of the slider 2. The surface of the rotating rod 7 is provided with a groove, which corresponds to the inner side of the guide wheel 8. When the rotating rod 7 is driven by the motor b6 to rotate, it will drive the guide wheel 8 installed on its surface to be fixed synchronously. The right side of the top of the slider 2 is fixedly connected to the motor b6. The output shaft of the motor b6 is fixedly connected to the rotation center shaft of the rotating rod 7. The surface of the rotating rod 7 contacts the guide wheel 8. A positioning and cleaning component 5 is detachably installed on the surface of the slider 2.

[0033] Reference Figure 2 and Figure 3 The positioning and cleaning component 5 includes a positioning seat 51. The side wall of the positioning seat 51 contacts the surface of the guide wheel 8. Through the contact between the positioning seat 51 and the guide wheel 8, the position of the guide wheel 8 installed on the surface of the rotating rod 7 is limited and fixed by the positioning seat 51, thereby preventing it from wobbling back and forth when rotating and driving the workpiece to rotate. The outer wall of the cleaning brush 56 contacts the outer arc surface of the guide wheel 8. The contact between the two allows the cleaning brush 56 to clean the welding slag and other debris generated during the welding process of the workpiece on the surface of the guide wheel 8, thereby preventing the workpiece from shaking when the rotation of the guide wheel 8 drives the workpiece to rotate, which would cause the welding position to deviate. The surface of the positioning seat 51 is provided with a groove. The inner wall of the groove of the positioning seat 51 contacts the surface of the rotating rod 7. The contact between the two allows the excess part after the guide wheel 8 is installed on the surface of the rotating rod 7 to be collected.

[0034] Reference Figure 3 and Figure 4 A slot is formed on the surface of the slider 2. The outer wall of the bottom end of the positioning seat 51 contacts the inner wall of the slot of the slider 2. An L-rod 52 is fixedly connected to the outer wall of the top end of the positioning seat 51. A collection box 54 is detachably installed on the surface of the L-rod 52 by bolts 53. The slot is formed on the surface of the L-rod 52, so that the bolts 53 can be rotated repeatedly with a special tool to pass through the slot of the L-rod 52 and be threadedly fixed to the collection box 54. A card plate 57 is snapped into the bottom end of the collection box 54. A plastic card block is provided on the surface of the card plate 57. By opening the card plate 57, the dust and impurities absorbed in the collection box 54 can be poured out. A cleaning brush 56 is provided on the left side surface of the collection box 54. A fan 55 is fixedly connected to the right side surface of the collection box 54. Multiple sets of through holes are formed on the surface of the collection box 54, so that the fan 55 can drive the internal suction to suck the debris cleaned by the cleaning brush 56 into the collection box 54 through the through holes.

[0035] Reference Figure 2 and Figure 4 A lever 59 is elastically connected to the inner wall of the bottom end of the positioning seat 51 via a return spring 58. One end of the return spring 58 is fixedly connected to the top of the outer wall of the lever 59, and the other end is fixedly connected to the top of the inner wall of the positioning seat 51. The function of the return spring 58 is to automatically reset the lever 59 after it has moved upward. The lever 59 is slidably connected to the inner wall of the bottom end of the positioning seat 51. A hinge rod 510 is hinged to the side wall of the lever 59, and a plug rod 511 is hinged to the end of the hinge rod 510 away from the lever 59. When the lever 59 moves upward, it will... Two sets of hinge rods 510 pull the corresponding insert rods 511 closer together, thereby disengaging them from the through hole at the bottom of the slider 2, which facilitates the disassembly of the positioning seat 51 and the replacement of the guide wheel 8. The insert rod 511 passes through and slides on the inner wall of the bottom of the positioning seat 51. The side wall of the empty groove of the slider 2 has a through hole. The outer wall of the insert rod 511 is inserted into the inner wall of the through hole. The insertion between the two can fix the positioning seat 51 on the surface of the slider 2, thereby stabilizing the guide wheel 8 on the surface of the rotating rod 7.

[0036] Reference Figure 1 and Figure 2 A slider 2 is fixedly connected to the outer sidewall of the base plate 1, and a bidirectional threaded rod 4 is rotatably connected to the inner wall of the guide groove of the base plate 1. The bottom end of the slider 2 is provided with an internal threaded groove. The slider 2 is threadedly connected to the surface of the bidirectional threaded rod 4. The output shaft of the motor a3 is fixedly connected to the rotation center shaft of the bidirectional threaded rod 4. Two sets of positive and negative spiral threads are provided on the surface of the bidirectional threaded rod 4. By rotating the bidirectional threaded rod 4, the two sets of sliders 2 can be brought closer to each other on their surfaces, thereby adjusting the contact area of ​​the guide wheel 8 according to the size of different workpieces. At the same time, by adjusting the left and right sets individually, the left and right shapes of the workpieces can be adjusted and fixed.

[0037] Working principle: When it is necessary to adjust the contact area between the guide wheels 8 according to the size of the workpiece, the motor a3 is started. The motor a3 drives the bidirectional threaded rod 4 to rotate. Due to the two sets of forward and reverse threads on the surface of the bidirectional threaded rod 4, the two sets of sliders 2 connected to it move closer or further apart on the surface of the bidirectional threaded rod 4. In this way, the spacing of the guide wheels 8 can be easily adjusted according to the workpiece of different sizes to meet the support requirements of workpieces of different sizes. For workpieces with different left and right shapes, the positions of the sliders 2 on both sides can be adjusted individually to achieve precise fixation of the workpiece and ensure the stability of the workpiece during the welding process.

[0038] During the welding process, motor b6 is started, and motor b6 drives the rotating rod 7 to rotate. Since the groove on the surface of the rotating rod 7 matches the inner side of the guide wheel 8, the rotation of the rotating rod 7 will drive the guide wheel 8 to rotate synchronously. The workpiece is placed on the guide wheel 8, and the rotation of the guide wheel 8 can drive the workpiece to rotate, which facilitates the welding operation from all directions.

[0039] When it is necessary to disassemble the positioning seat 51 to remove and replace the guide wheel 8, push the lever 59 upward. The lever 59 moves upward against the elastic force of the return spring 58. Through the two sets of hinge rods 510, the corresponding insertion rods 511 are pulled together. The insertion rods 511 disengage from the through hole at the current position of the bottom of the slider 2. At this time, the positioning seat 51 can be easily removed. After the operation is completed, release the lever 59. The return spring 58 makes the lever 59 automatically return to its original position, preparing for the next fixation of the positioning seat 51. At the same time, after the fan 55 is started, the internal suction force is generated. The cleaning brush 56 contacts the outer arc surface of the guide wheel 8 and sweeps off the welding slag and other debris generated on the surface of the guide wheel 8 during the processing and welding process. Under the suction force of the fan 55, these debris are sucked into the collection box 54 through the through hole. The bottom of the collection box 54 is connected to the card plate 57. By opening the card plate 57, the dust and impurities collected in the collection box 54 can be easily dumped.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
