DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The present application embodiment discloses an automated welding system for floor support members of a machine room. Figure 1 and 2As shown, it includes a frame 1, a rotating table 11 is arranged on the frame 1, and a loading device 14, a welding device 4 and a unloading device 7 are arranged around the rotating table 11. The structure of the support workpiece 8 includes a bottom plate 81 and a vertical pipe 82, the vertical pipe 82 is welded at the center position of one side of the bottom plate 81, and the axis of the vertical pipe 82 is perpendicular to the plate surface of the bottom plate 81, and a placement seat 12 for placing parts of the support workpiece 8 is arranged on the rotating table 11, the loading device 14 is used to place the bottom plate 81 and the vertical pipe 82 on the placement seat 12 in sequence, the welding device 4 is used to weld the vertical pipe 82 and the bottom plate 81, and the unloading device 7 is used to remove the support workpiece 8 that has completed the welding process from the placement seat 12. The feeding device 14 includes a first feeding mechanism 2 for feeding the bottom plate 81 and a second feeding mechanism 3 for feeding the vertical pipe 82. The first feeding mechanism 2, the second feeding mechanism 3, the welding device 4, and the unloading device 7 are uniformly distributed around the rotating table 11 along the rotation direction of the rotating table 11 in sequence; four placement seats 12 are provided and the four placement seats 12 are arranged in a circular array with the rotation axis of the rotating table 11 as the center. The table surface of the rotating table 11 is a horizontal plane, and a driving source (not shown in the figure) for driving the rotating table 11 to rotate in a directional manner is provided on the frame 1. In this embodiment, the driving source is a motor.

[0037] like Figure 2 and 3 As shown, the upper surface of the placement seat 12 is parallel to the table surface of the rotating table 11. After the workpiece is placed thereon, the lower surface of the bottom plate 81 fits with the upper surface of the placement seat 12. The upper surface of the placement seat 12 is fixedly connected with a clamping block 121 and a limiting block 122. There are four clamping blocks 121, which are evenly distributed on the opposite sides of the bottom plate 81 and abut against the side edge of the bottom plate 81. The limiting block 122 abuts against the side of the bottom plate 81 facing the axis of the rotating table 11. At this time, the clamping block 121 and the limiting block 122 realize the clamping and positioning of the bottom plate 81. The rotating table 11 is provided with a rotation-stopping assembly 6, which is used to control the relative stillness of the placement seat 12 relative to the rotating table 11, that is, to reduce the probability of the placement seat 12 rotating involuntarily. The anti-rotation assembly 6 includes a telescopic member 62 and a return spring 61. The telescopic member 62 slides relative to the rotating table 11, and the sliding direction is the radial direction of the rotating table 11. One end of the return spring 61 is fixedly connected to the rotating table 11, and the other end is fixedly connected to the sliding block 621. A stop hole 124 for inserting the telescopic member 62 is provided on one side of the placement seat 12. The length direction of the stop hole 124 is the radial direction of the placement seat 12. When the telescopic member 62 is inserted into the stop hole 124, the placement seat 12 cannot be easily rotated, and at this time, the limit block 122 is located on the side of the bottom plate 81 facing the axis of the rotating table 11.

[0038] like Figure 1 , 2As shown in Figure 4, the first feeding mechanism 2 includes a raw material barrel 21, a propulsion cylinder 22 and a transition assembly 23. The raw material barrel 21 is fixedly connected to the frame 1, and its length direction is the vertical direction. The raw material barrel 21 is used to stack several bottom plates 81 for raw materials. A gap is formed between the bottom of the raw material barrel 21 and the frame 1 for the bottom plates 81 to pass through. The propulsion cylinder 22 is fixedly connected to the frame 1 and is located on the side of the raw material barrel 21 away from the rotating table 11. The driving direction of the propulsion cylinder 22 is the radial direction of the rotating table 11. The transition assembly 23 is located between the raw material barrel 21 and the propulsion cylinder 22, and is used to transmit the propulsion force of the propulsion cylinder 22 to the bottom plate 81 in the raw material barrel 21. The existence of the transition assembly 23 is intended to improve the tightness of the bottom plate 81 with the limit block 122 and the clamping block 121 after the bottom plate 81 is loaded, and at the same time, it is also possible to avoid damage to the bottom plate 81 caused by the transition propulsion of the piston rod of the propulsion cylinder 22. The transition assembly 23 includes a pressure cylinder 231, a slide bar 232, a reset air pipe 233 and a push plate 234. The pressure cylinder 231 is fixedly connected to the frame 1 and coaxial with the push cylinder 22. The slide bar 232 is slidably connected to the pressure cylinder 231 and both ends thereof extend from both ends of the pressure cylinder 231. A piston block is coaxially formed in the middle of the slide bar 232, and the piston block contacts the inner wall of the pressure cylinder 231. One end of the reset air pipe 233 is connected to the pressure cylinder 231 and the connection point is located on the side of the piston block away from the push cylinder 22. The other end of the reset air pipe 233 is connected to the air source (not shown in the figure). The pressure cylinder 231 is also provided with a pressure relief hole 2311, which is also located on the side of the piston block away from the push cylinder 22. The push plate 234 is fixedly connected to the side of the slide bar 232 away from the push cylinder 22, and the side of the push plate 234 away from the slide bar 232 abuts against the side of the bottom plate 81 away from the rotating table 11. The piston rod of the propulsion cylinder 22 extends out quickly, hits the slide bar 232 and pushes it and the propulsion plate 234. The propulsion plate 234 finally pushes the lowest bottom plate 81 out of the raw material barrel 21 through the gap at the bottom of the raw material barrel 21 and pushes it onto the placement seat 12; at the moment when the piston rod of the propulsion cylinder 22 is extended to the maximum length, the bottom plate 81 does not touch the limit block 122, and the slide bar 232 continues to move forward due to inertia until the edge of the bottom plate 81 touches the limit block 122, then it stops naturally, and then the air source is started, and the air flow generates pressure on the piston block to cause the piston block and the slide bar 232 to move in the opposite direction, thereby realizing the resetting of the slide bar 232.

[0039] like Figure 1 and 5As shown, after the bottom plate 81 is loaded, the rotating table 11 rotates 90°, carrying the placement seat 12 of the bottom plate 81 to the second loading mechanism 3. The second loading mechanism 3 includes a centrifugal disc 31, a feeding pipe 32, a feeding cylinder 33 and a clamp 34. The centrifugal disc 31 is fixedly connected to the frame 1 and is located on one side of the rotating table 11. The feeding pipe 32 is fixedly connected to the discharge end of the centrifugal disc 31. The feeding cylinder 33 is fixedly connected to the frame 1 and its own axis is the radial direction of the rotating table 11. The clamp 34 is arranged at the end of the piston rod of the feeding cylinder 33 and is located below the port of the feeding pipe 32 away from the centrifugal disc 31. The clamp 34 includes a fixed block 341 and a cantilever hook 342. The cantilever hook 342 is hinged to one end of the fixed block 341 away from the feeding cylinder 33 and a torsion spring is arranged between the two. When the vertical pipe 82 falls out of the feeding pipe 32, the vertical pipe 82 is located between the fixed block 341 and the cantilever hook 342, and there is still a gap between the two and the side wall of the vertical pipe 82 to increase the probability of the vertical pipe 82 falling successfully, and the vertical pipe 82 will not fall at a large angle. The feeding cylinder 33 pushes the piston rod, and the fixed block 341 pushes the vertical pipe 82 to move to the center of the bottom plate 81 on the placement seat 12 of the rotating table 11.

[0040] like Figure 1 , 3 As shown in Figure 5, a press-fitting assembly 13 is also provided on the rotating table 11. The press-fitting assembly 13 is used to position the vertical tube 82 on the placement seat 12 and apply a vertical force to it. The press-fitting assembly 13 includes a press cylinder 131, a connecting block 132 and a fixed axis column 133. The press cylinder 131 is fixedly connected to the rotating table 11 and its telescopic direction is the vertical direction. The connecting block 132 is slidably connected to the frame 1 and is fixedly connected to the piston rod of the press cylinder 131. The fixed axis column 133 is rotatably connected to the connecting block 132. The rotation axis of the fixed axis column 133 coincides with the rotation axis of the placement seat 12. The bottom end surface of the fixed axis column 133 is coaxially provided with a snap-fit ​​groove 1331. The press cylinder 1 After the piston rod 31 is extended, the bottom of the locking groove 1331 abuts against the top of the vertical tube 82. At this time, the vertical tube 82 is subjected to the vertical downward force from the fixed shaft column 133, and its position is relatively stable, that is, the feeding operation of the vertical tube 82 is completed, and the piston rod of the feeding cylinder 33 can be retracted. When retracting, the vertical tube 82 produces a certain space obstruction to the cantilever hook 342 of the clamping jaw 34, and the cantilever hook 342 is forced to deflect; when the clamping jaw 34 is separated from the vertical tube 82, the torsion spring resets the cantilever hook 342.

[0041] like Figure 1 and 3As shown, after the vertical tube 82 is loaded, the rotating table 11 rotates 90°, carrying the bottom plate 81 and the placement seat 12 of the vertical tube 82 to the welding device 4. The welding device 4 includes a welding cylinder 42 and a welding gun 41. The welding cylinder 42 is fixedly connected to the frame 1, and its axis is at an angle of 45° with the horizontal plane. The welding gun 41 is fixedly connected to the end of its piston rod. When the piston rod of the welding cylinder 42 is extended to the maximum length, the muzzle of the welding gun 41 is facing the joint of the vertical tube 82 and the bottom plate 81 and welding can be started. The welding device 4 also includes a control component 5, which is used to control the placement seat 12 to rotate at the welding gun 41; the control component 5 includes a lifting cylinder 51, a synchronous motor 52 and a synchronous block 53. The bottom of the placement seat 12 is fixedly connected with a matching block 123. The lifting cylinder 51 is fixedly connected to the frame 1 and is located below the rotating table 11. The synchronous motor 52 is fixedly connected to the end of the piston rod of the lifting cylinder 51. The synchronization block 53 is fixedly connected to the output end of the synchronous motor 52. A matching groove 531 matching with the matching block 123 is provided on the top of the synchronization block 53. The cross-section of the matching block 123 is non-circular (in this embodiment, the matching block 123 is an elliptical curved protrusion), that is, when the synchronization block 53 and the matching block 123 cooperate with each other, the synchronization block 53 and the placement seat 12 can achieve synchronous rotation.

[0042] like Figure 3As shown, the anti-rotation assembly 6 also includes a sensing block 63, which is slidably connected to the placement seat 12 and the sliding direction is the vertical direction. The placement seat 12 is also provided with a spring 65, one end of the spring 65 is fixedly connected to the placement seat 12, and the other end is fixedly connected to the top of the sensing block 63. The lower end of the sensing block 63 away from the spring 65 faces the synchronization block 53. When it is necessary to control the rotation of the placement seat 12, the lifting cylinder 51 extends the piston rod, the synchronization block 53 rises and pushes the sensing block 63, and the spring 65 will be compressed and deformed. The telescopic member 62 includes a sliding block 621 and a roller 622. The roller 622 is rotatably connected to one end of the sliding block 621 away from the reset spring 61, and the rotation axis of the roller 622 is parallel to the rotation axis of the placement seat 12. A response piston plate 64 is slidably arranged in the anti-rotation hole 124, and the response piston plate 64 is in contact with the roller 622; when the spring plate 65 is bent under pressure, the side of the response piston plate 64 away from the telescopic member 62 is abutted and pushed by the spring plate 65, and when the synchronization block 53 and the matching block 123 cooperate with each other, the telescopic member 62 is also pushed to the hole mouth of the anti-rotation hole 124, and at this time, when the placement seat 12 rotates, the roller 622 can roll out of the anti-rotation hole 124, and the placement seat 12 can also be smoothly driven by the control component 5 to rotate. During the rotation process, the roller 622 rolls one circle relative to the placement seat 12, and the welding gun 41 performs welding work synchronously during the rotation process; after the rotation is completed, the roller 622 is sunk into the anti-rotation hole 124 again, and the piston rod of the lifting cylinder 51 descends. Under the reset action of the spring plate 65 and the reset spring 61, the telescopic member 62 enters the anti-rotation hole 124 again, and the placement seat 12 and the rotating table 11 enter a relatively static state again.

[0043] like Figure 6 As shown, after the welding is completed, the rotating table 11 rotates 90° again, carrying the placement seat 12 of the bottom plate 81 and the vertical pipe 82 to the unloading device 7. The unloading cylinder 71, the hook sickle block 72 and the finished product box 73, the unloading cylinder 71 is fixedly connected to the frame 1, the hook sickle block 72 is fixedly connected to the piston rod end of the unloading cylinder 71, and the finished product box 73 is placed on the ground on one side of the rotating table 11. When waiting for the support workpiece 8 to arrive, the piston rod of the unloading cylinder 71 is in an extended state, and when the rotating table 11 turns around with the placement seat 12 on which the support workpiece 8 is placed, the hook sickle block 72 contacts the side wall of the vertical pipe 82 along the rotation direction of the rotating table 11, and at this time, a part of the hook sickle block 72 is located on the side of the vertical pipe 82 away from the unloading cylinder 71. Then, the piston rod of the pressing cylinder 131 contracts, the piston rod of the unloading cylinder 71 contracts, and the hook block 72 pushes the supporting workpiece 8 to move away from the limit block 122, thereby leaving the placement seat 12 and sliding into the finished product box 73. After the rotating table 11 continues to rotate 90°, the empty placement seat 12 comes to the first feeding mechanism 2 for the feeding device 14 to feed again, thus entering the next round of processing cycle.

[0044] The implementation principle of the automatic welding system for floor support members of a machine room according to the embodiment of the present application is as follows:

[0045] The loading device 14 performs automatic loading, the welding device 4 performs welding processing on the workpiece material on the placement seat 12, and then the unloading device 7 pushes the support material off the placement seat 12 to complete the unloading, and then the placement seat 12 is vacant, and the rotating table 11 continues to rotate. The empty placement seat 12 can be used for the loading device 14 to load again, thereby entering the next round of processing cycle.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
