DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Please refer to Figures 1 to 10. The present invention provides a technical solution: an automatic calibration welding device for a distribution box, comprising a welding table 1, and also comprising an adjustment plate 2 and a flip plate 3. When the adjustment plate 2 is displaced, the flip plate 3 is driven to be displaced. A clamp 1 is extended from the side wall of the flip plate 3, which is used to fix the distribution box. A flip mechanism is provided between the adjustment plate 2 and the flip plate 3. The flip mechanism controls the rotation of the flip plate 3 to adjust the angle of the distribution box. A direct welding component is provided on one side of the welding table 1. The direct welding component is used to weld the top corner line of the distribution box. Clamps 2 are extended from both sides of the direct welding component. The clamps 2 are used to clamp and fix the vertically placed distribution box machine. A conveyor path 4 and a conveyor component are provided on one side of the welding table 1. The conveyor component is used to automatically unload the distribution box along the trajectory of the conveyor path 4.

The flipping mechanism includes a rotating shaft 1 5 and a rotating shaft 2 6, and the rotating shaft 1 5 and the rotating shaft 2 6 are respectively arranged at the two ends of the bottom of the flip plate 3, and the rotating shaft 1 5 is arranged in parallel with the rotating shaft 2 6, and the rotating shaft 1 5 is located at one end close to the direct welding component. An arc groove block 7 is provided on the side of the adjustment plate 2. When the flip plate 3 is parallel to the adjustment plate 2, the rotating shaft 1 5 and the rotating shaft 2 6 are respectively matched with the arc groove block 7, and a gear 1 8 is provided at the end of the rotating shaft 1 5, and a gear 2 9 is provided at the end of the rotating shaft 2 6. The side wall of the adjustment plate 2 is provided with a rack group meshing with the gear 1 8 and the gear 2 9. At the same time point, the gear 1 8 or the gear 2 9 is meshed with the rack group.

The rack group includes a rack 10, a rack 2 11 and a connecting rod 12, wherein the rack 10 and the rack 2 11 are both fixedly connected to the connecting rod 12, and the connecting rod 12 is fixedly connected to the telescopic rod of a cylinder 13. When the connecting rod 12 is displaced, the rack 10 and the rack 2 11 are driven to displace, and when the rack 10 is meshed with the gear 1 8, the distribution box is driven to rotate with the rotating shaft 1 5 as the center, and when the rack 2 11 is meshed with the gear 2 9, the distribution box is driven to rotate with the rotating shaft 2 6 as the center.

The specific implementation method of adjusting the angle of the distribution box is as follows: if the distribution box needs to be changed to a vertical state for welding, it is necessary to control the rotation of the distribution box with the rotating shaft 5 as the origin. At this time, the cylinder 13 can be used to drive the connecting rod 12 to move, so that the connecting rod 12 drives the rack 10 to move toward the gear 8 until the rack 10 is meshed with the gear 8. When the two are meshed, the rotating shaft 5 will be driven to rotate, and the rotating shaft 5 will drive the flip plate 3 to rotate. Since the flip plate 3 is in a relatively fixed state with the distribution box through the clamp 1 at this time, the flip plate 3 will drive the distribution box to flip and change the angle of the distribution box. Similarly, if the rack 2 11 is controlled to move to a position meshing with the gear 2 9, the distribution box can be rotated with the rotating shaft 2 origin to adjust the angle of the distribution box. When welding the top angle line of the back plate, the distribution box can be adjusted to an inclined state so that the distribution box is tilted to one side of the welding gun. This makes it convenient for the welding gun to weld the distribution box, making welding more convenient.

The clamp 1 includes a clamp 14 and a clamp 2 15, and the two clamps 14 are symmetrically arranged. The two clamps 14 are displaced synchronously to clamp and fix the side wall of the distribution box. The clamp 2 15 is arranged at an end away from the direct welding assembly. When the clamp 2 15 is displaced, the distance between the end of the distribution box and the direct welding assembly is adjusted; the clamp 14 and the clamp 2 15 are symmetrically sleeved on the outer wall of the two-way screw rod 16, and the end of the two-way screw rod 16 is fixedly connected to the output shaft of the driving motor 17. When the two-way screw rod 16 rotates, the clamp 14 and the clamp 2 15 are driven to displace synchronously. The clamp 2 15 is sleeved on the outer wall of the unidirectional screw rod 18, and the end of the unidirectional screw rod 18 is fixedly connected to the output shaft of the driving motor 2 19. When the unidirectional screw rod 18 rotates, the clamp 2 15 is driven to displace.

The specific implementation method of clamping the distribution box by a pair of clamps is as follows: when the distribution box is covered on the outside of the adjustment plate 2, the drive motor 19 can be started first to drive the one-way screw 18 to rotate. Since a screw nut matching the one-way screw 18 is provided inside the clamp 15, the clamp 15 will be displaced with the rotation of the one-way screw 18. At this time, after the clamp 15 contacts the inner wall of the distribution box, a thrust will be generated on the distribution box. If the inner wall of the other end of the distribution box is not in contact with the adjustment plate 2, the distribution box will be displaced with the clamp 15 until the distribution box can no longer be displaced with the clamp 15. At this time, the one-way screw 18 can be stopped from rotating. In this way, the distance between the end of the distribution box close to the rotating shaft 5 and the straight welding plate 21 can be ensured, so that the distribution box can be displaced in a circle with the rotating shaft 5 as the circle. When the center rotates, after the distribution box is adjusted to a vertical state, the distance between it and the straight welding plate 21, and the length position of the distribution box are adjusted, the drive motor 17 can be started at this time, so that the drive motor 17 drives the bidirectional screw rod 16 to rotate. Since the inside of the clamp 14 and the clamp 2 15 are provided with screw nuts matching the bidirectional screw rod 16, the rotation of the bidirectional screw rod 16 will drive the clamp 14 and the clamp 2 15 to move synchronously, so that the clamp 14 and the clamp 2 15 are in contact with the inner wall of the distribution box. When the clamp 14 and the clamp 2 15 are completely in contact with the inner wall of the distribution box, a lateral clamping force can be generated on the distribution box to fix the distribution box. In addition, in the process of fixing the distribution box, the position of the distribution box can also be corrected to ensure the normal progress of subsequent welding.

A hydraulic cylinder 20 is provided at the bottom of the adjustment plate 2. When the telescopic end of the hydraulic cylinder 20 is displaced, the adjustment plate 2 is driven to be displaced. The size of the adjustment plate 2 is smaller than the size of the flip plate 3. Specifically, during welding, the height of the distribution box can be adjusted by the hydraulic cylinder 20. In this way, when welding the four-legged wire, a safe distance can be created between the end of the four-legged wire and the welding table 1 to avoid damage to the welding table 1 caused by the high temperature generated during welding. In addition, when adjusting the angle of the distribution box, the distribution box can be raised a certain distance to ensure that the distribution box can be flipped normally to avoid the end of the distribution box colliding with the welding table 1.

The direct welding assembly includes a direct welding plate 21, which is located at one side of the conveying path 4. A clamp three 22 is provided above the direct welding plate 21. The clamp three 22 is rotatably connected to a threaded rod 23. One end of the threaded rod 23 extends into the interior of the direct welding plate 21. A threaded sleeve 24 matching the threaded rod 23 is provided inside the direct welding plate 21. The threaded sleeve 24 is fixedly connected to the output shaft of a drive motor three 25. A guide plate 26 is provided at one end of the clamp three 22. A guide frame 27 matching the guide plate 26 is provided on the side wall of the direct welding plate 21. When the threaded rod 23 rotates, the clamp three 22 drives the guide plate 26 to move along the trajectory of the guide frame 27.

The clamp 2 includes a clamp arm 1 28 and a clamp arm 29, and there is an angle between the clamp arm 1 28 and the clamp arm 2 29. One end of the clamp arm 1 28 on both sides is hinged to the straight welding plate 21 through a hinge shaft 1 and a hinge shaft 2. The outer wall of the hinge shaft 1 is sleeved with a gear 30, and the outer wall of the hinge shaft 2 is sleeved with a gear 4 31. The gear 30 is meshed with the gear 5 32, and the gear 5 32 is meshed with the rack 3 33. The rack 3 33 is meshed with the gear 4 31, and the rack 3 33 is not meshed with the gear 3 30. When the rack 3 33 moves with the electric linear slide 1 34, the gear 3 30 and the gear 4 31 rotate in opposite directions at the same time.

The specific implementation of the direct welding assembly is as follows: when the distribution box is fully adjusted to be perpendicular to the welding table 1, the distribution box can be placed in the conveyor 4, and the clamp 1 is loosened. At this time, the electric linear slide 1 34 is used to drive the rack 3 33 to move, and the rack 3 33 is meshed with the gear 4 31, which will drive the gear 4 31 and the gear 5 32 to rotate synchronously, and the rotation of the gear 5 32 will drive the meshing gear 3 30 to rotate. According to the principle of gear meshing, at this time, the gear 4 31 and the gear 3 30 rotate in opposite directions, and the gear 3 30 and the gear 4 31 will drive their respective articulated shafts 1 and 2 to rotate, thereby driving the clamp arms 1 28 on both sides to rotate inward at the same time to calibrate the position of the distribution box. During the calibration process The clamp arm 1 28 contacts the distribution box at point A, and the clamp arm 29 contacts the distribution box at point B. The forces acting on points A and B can correct the angle of the distribution box so that the distribution box is level with the straight welding plate 21. After the distribution box is clamped and fixed by the clamp 2, the drive motor 3 25 can be started, which will drive the threaded sleeve 24 to rotate. Since the guide plate 26 and the guide frame 27 cooperate to limit the clamping jaw 3 22, the rotation of the threaded sleeve 24 drives the displacement of the threaded rod 23 through the principle of threaded engagement. The threaded rod 23 will drive the displacement of the clamping jaw 3 22, and move the clamping jaw 3 22 to fix the top of the distribution box to ensure the stability of the distribution box during the welding process.

The conveying assembly includes a support frame 35, and a connecting rod 36 is provided inside the support frame 35. One end of the connecting rod 36 extends to the outside of the support frame 35 and is fixedly connected to a hook rod 37. A connecting block 38 is provided on the top of the connecting rod 36 for rotation. A tension spring 39 is provided between the hook rod 37 and the connecting block 38. When the angle of the hook rod 37 is adjusted, the tension spring 39 generates a pulling force on the hook rod 37 so that the angle between the hook rod 37 and the support frame 35 is always less than one hundred and eighty degrees. When the connecting block 38 moves with the electric linear slide rail 40, it drives the connecting rod 36 to move along the guide groove 41. A hook head 42 is provided at one end of the hook rod 37, and a one-way piece is provided inside the guide groove 41. When the connecting rod 36 moves to engage with the one-way piece, the connecting rod 36 rotates.

The one-way member includes a gear six 43 and a gear seven 44, and the gear six 43 and the gear seven 44 are sleeved on the outer wall of the connecting rod two 36. A rack four 45 and a rack five 46 are provided in the guide groove 41, and the rack four 45 and the rack five 46 are respectively provided at two ends of the guide groove 41. A ratchet 47 and a pawl 48 are provided between the gear six 43 and the gear seven 44 and the connecting rod two 36. When the gear six 43 is engaged with the rack four 45, the connecting rod two 36 is driven to rotate unidirectionally, and the rotation direction is direction one. When the gear seven 44 is engaged with the rack five 46, the connecting rod two 36 is driven to rotate unidirectionally, and the rotation direction is direction two. The direction one is opposite to the rotation direction of the direction two.

The ratchet 47 is arranged on the inner wall of the gear six 43 and the gear seven 44, the pawl 48 is hingedly arranged on the outer wall of the connecting rod two 36, and an elastic sheet is arranged between the pawl 48 and the connecting rod two 36, which can produce an automatic reset effect on the pawl 48.

The specific implementation method for cutting the distribution box is as follows: when the welding of the distribution box is completed, the electric linear slide rail 2 40 can be used to drive the connecting rod block to move, and the connecting block 38 will drive the connecting rod 2 36 to move, and the connecting rod 2 36 will drive the gear 6 43 to move to mesh with the rack 4 45, and the gear 6 43 will rotate forward. At this time, with the cooperation of the ratchet 47 and the pawl 48, the connecting rod 2 36 will be driven to rotate, and the connecting rod 2 36 will drive the hook rod 37 to rotate, and move the hook head 42 of the hook rod 37 to the inside of the distribution box, and then drive the connecting rod 2 36 to move in the opposite direction. At this time, when the gear 6 43 is meshed with the rack 104 again, its rotation direction is opposite to the previous time, that is, reverse rotation. According to the ratchet 47 and the pawl The operating principle of 48 is that at this time, gear six 43 rotates, but connecting rod two 36 does not rotate, so the direction of hook rod 37 does not change. At this time, it moves backward and can use hook rod 37 to pull the distribution box outward, so that the distribution box can be unloaded along the trajectory of conveyor 4 until gear seven 44 on connecting rod two 36 is engaged with rack five 46. At this time, the rotation of gear seven 44 will drive connecting rod two 36 to rotate to the initial position, so that the hook head 42 can be removed from the distribution box, so that the hook head 42 no longer hooks and pulls the distribution box, and the automatic unloading of the distribution box is completed without manual unloading. The vertically placed distribution box is more convenient for unloading, whether it is manually picked up after cooling or grabbed by a robotic arm. The vertically placed distribution box is more convenient for unloading.

The specific implementation of the device is as follows: the distribution box is opened downward and placed flat on the welding table 1, and the distribution box is fixed by a pair of clamps. At this time, the corner line close to the welding gun side can be welded first. After the welding of this end is completed, the angle of the distribution box can be adjusted. The distribution box can be adjusted to an inclined state, or directly adjusted to a state perpendicular to the welding table 1. At this time, the clamp arm and the clamp claw 3 22 can be used to clamp and fix the distribution box in a vertical state, and then the corner line at the top can be welded, which reduces the path length that the welding gun needs to move and improves the welding work efficiency. The corner line is separated from the welding table 1, which is convenient for welding and reduces damage to the welding table 1. After adjusting to a vertical state, the inside of the distribution box can be welded to achieve multi-sided welding. The whole process is quick and convenient. After the welding is completed, the hook rod 37 can be used to automatically unload the distribution box to avoid the situation where high temperature burns are easily caused by manual unloading after welding. In addition, the vertically placed distribution box is more convenient to remove from the welding table 1 than the state of being horizontally inverted on the welding table 1.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
