Abstract
Description
Technical Field
[0001] The invention relates to the technical field of welding equipment, in particular to a welding equipment for building scaffolding. Background Art
[0002] In the manufacturing process of disc-type scaffolding, the traditional method requires manual placement of discs one by one on the welding fixture. There are two major technical pain points in this process: first, the operator needs to repeatedly grab, position and fix the discs, resulting in an exponential increase in labor time; second, to ensure the assembly compatibility of the subsequent crossbar pins, the circumferential notch of each disc must maintain a strictly consistent phase angle (usually the error needs to be controlled within ±3°), and the operator needs to make fine adjustments by comparing the positioning marks with the naked eye. The rhythm instability caused by manual operation causes the automated welding equipment to have to operate at a reduced frequency. This process defect directly restricts the large-scale standardized production of disc-type scaffolding, resulting in efficiency loss and quality fluctuations; and in the rod-through welding process, when the vertical pole is inserted into the disc group in a single-end clamping manner, a typical cantilever beam structure is formed. As the penetration depth increases, the free end of the vertical pole is subjected to flexural deformation under the action of gravity. In the disc-type scaffolding welding process, as shown in the attached figure, Figure 1 and attached Figure 11 As shown, there are matching requirements between the disc and the pole, but the pole is relatively long. During the insertion process, the pole acts as a gradually elongated cantilever beam. This will result in that as the number of discs fitted with the pole increases, the coaxiality of the pole and the subsequent discs will gradually decrease, which will lead to: on the one hand, the gaps N1 and N2 between the inner hole of the disc and the upper and lower sides of the pole will be unevenly distributed, which may easily lead to a larger weld on the upper side; and such uneven distribution will become more severe as the pole is inserted, that is, N1 is greater than N3 and N2 is less than N4, which may easily lead to uneven connection strength during welding; on the other hand, when the design gap between the inner diameter of the disc and the outer diameter of the pole is small, collision is likely to occur during the insertion of the disc.
[0003] Based on this, the present invention designs a building scaffold welding device to solve the above problems. Summary of the Invention

A discharge port 12 is provided on one side of the storage box 13. A screw rod 9 is rotatably connected to the storage box 13. A push plate 8 is spirally connected to the screw rod 9. An adjustment unit is also provided on the storage box 13. See also Figure 2 、 Figure 3 、 Figure 5 Before welding, multiple discs 30 are placed in batches in the storage box 13. The adjustment unit controls the movement of a single disc 30 through the discharge port 12 to the inside of the slide 20, which is then driven to slide inside the fixed frame 18 until it contacts the transmission rod 28 (see Figure 9 As shown), pass the vertical rod 31 through the disk 30, start the driving unit 2 to weld and fix the connection between the disk 30 and the vertical rod 31. The purpose of doing this is to control the movement and feeding of a single disk 30 through the adjustment unit, which can effectively reduce the impact of manual loading of the disk 30 on the welding efficiency during the welding process.
[0017] As a further solution of the present invention, the adjustment unit includes a fixed plate 5, which is arranged above the storage box 13, and the side wall of the fixed plate 5 is fixedly connected to a plurality of docking rods 6, and the side wall of the storage box 13 is fixedly connected to a plurality of docking notches 11 corresponding to the docking rods 6, the bottom end of the fixed plate 5 is fixedly connected to two limit rods 7, the top of the storage box 13 is fixedly connected to a telescopic member 14, the output end of the telescopic member 14 is fixedly connected to a convex shaft 15 corresponding to the limit rod 7, and the side wall of the storage box 13 is fixedly connected to a motor 10, and the output end of the motor 10 is fixedly connected to a screw rod 9; The fixed frame 18 is internally rotatably connected to the screw rod 2 17, the bottom of the sliding frame 20 is spirally connected to the screw rod 2 17, the side wall of the sliding frame 20 is fixedly connected to the telescopic member 24, the output end of the telescopic member 24 is fixedly connected to the docking plate 19, and the top side wall of the docking plate 19 is fixedly connected to the convex shaft 22 corresponding to the convex shaft 15; See also Figure 3-Figure 6, since cavities are provided at symmetrical positions on the disc 30, it is only necessary to connect two of the cavities with the limit rod 7 to fix the disc 30 in a fixed position and slide it onto the limit rod 7. In this way, several discs 30 are simultaneously sleeved on the limit rod 7 in the same position. When feeding, the motor 10 is started to drive the screw rod 9 to rotate, which can drive the push plate 8 to slide and push the disc 30 to slide relative to the limit rod 7. When the disc 30 is about to break away from the contact with the limit rod 7, the disc 30 will slide to the position in contact with the cam 15 and sleeve on the cam 15, that is, the disc 30 is transferred from the limit rod 7 to the cam 15, and then the motor 10 stops working, and the telescopic part 14 drives the cam 15 to slide downward, so that the cam 15 drives the disc 30 to pass through the discharge port 12 together until the disc 30 slides to the inside of the sliding rack 20; like Figure 8 As shown, when the telescopic member 14 drives the disc 30 to slide downward to the inside of the sliding frame 20, the bottom of the disc 30 will contact the convex shaft 22. The tops of the convex shaft 15 and the convex shaft 22 are both provided with inclined surfaces, and the convex shaft 15 and the convex shaft 22 are telescopic rods with elastic components inside. When the bottom surface of the disc 30 contacts the inclined surface of the convex shaft 22, the convex shaft 22 will be pushed to retract inward, and as the disc 30 gradually slides down until the convex shaft 22 docks with the cavity at the bottom of the disc 30, the disc 30 slides the length L1 at this time, and under the action of the restoring elastic force of the elastic component, the convex shaft 2 is pushed to return to the cavity at the bottom of the disc 30, and the disc 30 is transferred from the telescopic member 14 to the sliding frame. 20, and then the telescopic part 14 resets upward. At this time, the disc 30 is restricted by the convex shaft 22 and cannot continue to slide upward with the telescopic part 14, and the inclined surface of the top of the convex shaft 15 will be squeezed with the inner wall of the disc 30 under the pulling force of the telescopic part 14, so that the convex shaft 15 shrinks and separates from the disc 30, until the convex shaft 15 is separated from the contact with the disc 30 and the convex shaft 15 is reset under the action of the elastic component until the telescopic part 14 slides upward to the initial position. The purpose of this is to ensure that the orientation of the disc 30 remains unchanged while the disc 30 is transported, so that when the disc 30 is subsequently docked with the vertical pole 31, the vertical pole 31 can be directly passed through the disc 30 for welding and fixing.
[0018] As a further solution of the present invention, the rear end of the telescopic member 24 is fixedly connected to a mortise rod 25, the top of the sliding rod 21 is fixedly connected to a mortise block 26 corresponding to the mortise rod 25, the bottom end of the sliding rod 21 is fixedly connected to a reset spring 27 for its reset, the front end of the fixed frame 18 is fixedly connected to the motor 2 16, the output end of the motor 2 16 is fixedly connected to the screw rod 2 17, the inner wall of the bottom end of the sliding frame 20 is a smooth inclined surface, and the top surface of the front end of the transmission rod 28 is the same inclined surface as the inner wall of the bottom end of the sliding frame 20; See also Figure 9After the disc 30 is transferred to the interior of the sliding frame 20, the second motor 16 drives the second screw rod 17 to rotate, driving the sliding frame 20 to slide along the fixed frame 18 until the sliding rod 21 slides to a position where it contacts the transmission rod 28 and cannot slide further. In this way, the sliding distance of the sliding frame 20 can be limited by the transmission rod 28, so that each disc 30 can slide the same distance L2 under the drive of the sliding frame 20; then, the vertical rod 31 is passed through multiple discs 30, and the connection between the disc 30 and the vertical rod 31 is welded and fixed by the driving unit 2; like Figure 10 As shown, after welding is completed, the telescopic part three 29 drives the transmission rod 28 to slide downward a distance L3. At this time, the transmission rod 28 will drive the sliding rod 21 to compress the reset spring 27 and slide down together, breaking away from the limit of the sliding rod 21 on the disc 30, and because the bottom surface of the sliding frame 20 and the top surface of the transmission rod 28 are both inclined surfaces, after the transmission rod 28 slides down, the top surface of the transmission rod 28 is in contact with the bottom surface of the sliding frame 20, so that the disc 30 slides along the top surface of the transmission rod 28 after being welded to the vertical rod 31, realizing the transportation of the vertical rod 31 after the welding is completed, and then the telescopic part three 29 is driven to drive the transmission rod 28 to reset. Under the reset elastic force of the reset spring 27, the sliding rod 21 is also reset. Then the sliding frame 20 is controlled to reset by the screw rod 217, and the disc 30 and the vertical rod 31 are repeatedly transported for welding.
[0019] As a further solution of the present invention, the top end of the docking plate 19 is rotatably connected to a transmission belt 23; See also Figure 11 When the vertical rod 31 is directly docked with the disk 30, since the vertical rod 31 is a cantilever beam structure supported at only one end, the free end of the vertical rod 31 is bent and deformed under the action of gravity during the sliding process of the vertical rod 31 through the pipe, resulting in a height difference of H2 at the free end of the vertical rod 31 during the docking process; Figure 6 As shown, a docking plate 19 with an inclined surface is added in front of the disc 30. When a height difference occurs at the free end of the vertical rod 31, causing the free end to be positioned downward, the free end of the vertical rod 31 will first contact the docking plate 19 and, under the action of the thrust, slide upward along the inclined surface of the docking plate 19 to the position docking with the disc 30; the transmission belt 23 is used to replace the docking plate 19 in contact with the vertical rod 31, so that the vertical rod 31 contacts the transmission belt 23 and drives the transmission belt 23 to rotate, and rolling friction is used instead of sliding friction, thereby further reducing the wear between the docking plate 19 and the disc 30, and improving the docking accuracy of the disc 30 and the vertical rod 31.
[0020] As a further solution of the present invention, a support plate 4 is provided on one side of the fixing frame 18, and the top end of the support plate 4 is fixedly connected to the bottom end of the storage box 13; See also Figure 2The bottom of the storage box 13 is supported and fixed by the support plate 4 so that the sliding frame 20 will not affect the stability of the storage box 13 when sliding.
[0021] Working principle: Before welding, multiple discs 30 are put into the interior of the storage box 13 in batches. Since cavities are opened at symmetrical positions on the discs 30, it is only necessary to connect two of the cavities with the limit rod 7 to fix the disc 30 in a fixed position and slide it on the limit rod 7. In this way, multiple discs 30 are simultaneously sleeved on the limit rod 7 in the same position. When feeding, the motor 10 is started to drive the screw rod 9 to rotate, which can drive the push plate 8 to slide and push the disc 30 to slide relative to the limit rod 7. When the disc 30 is about to break away from the contact with the limit rod 7, the disc 30 will slide to the position of contact with the cam 15 and sleeve on the cam 15, that is, the disc 30 is transferred from the limit rod 7 to the cam 15, and then the motor 10 stops working, and the telescopic part 14 drives the cam 15 to slide downward, so that the cam 15 drives the disc 30 to pass through the discharge port 12 together until the disc 30 slides to the inside of the sliding rack 20; When the telescopic member 14 drives the disc 30 to slide downward to the inside of the sliding frame 20, the bottom of the disc 30 will contact the convex shaft 22. The tops of the convex shaft 15 and the convex shaft 22 are both provided with inclined surfaces, and the convex shaft 15 and the convex shaft 22 are telescopic rods with elastic components inside. When the bottom surface of the disc 30 contacts the inclined surface of the convex shaft 22, the convex shaft 22 will be pushed to retract inward, and as the disc 30 gradually slides down until the convex shaft 22 docks with the cavity at the bottom of the disc 30, the disc 30 slides the length L1 at this time, and the convex shaft 22 is pushed back to the insertion position under the reset elastic force of the elastic component. The disc 30 is inserted into the cavity at the bottom of the disc 30. At this time, the disc 30 is transferred from the telescopic member 14 to the interior of the sliding frame 20. Then the telescopic member 14 is reset upward. At this time, the disc 30 is restricted by the convex shaft 22 and cannot continue to slide upward with the telescopic member 14. The inclined surface of the top of the convex shaft 15 is squeezed against the inner wall of the disc 30 under the pulling force of the telescopic member 14, causing the convex shaft 15 to shrink and separate from the disc 30. After the convex shaft 15 is released from contact with the disc 30, it is reset under the action of the elastic component until the telescopic member 14 slides upward to its initial position. When the disc 30 is transferred to the interior of the sliding frame 20, the motor 2 16 drives the screw 2 17 to rotate, driving the sliding frame 20 to slide along the fixed frame 18 until the sliding rod 21 slides to a position where it contacts the transmission rod 28 and cannot slide further. In this way, the sliding distance of the sliding frame 20 can be limited by the transmission rod 28, so that each disc 30 can slide the same distance L2 under the drive of the sliding frame 20; then the vertical rod 31 passes through multiple discs 30, and the connection between the disc 30 and the vertical rod 31 is tightened by the driving unit 2. After welding and fixing, after welding is completed, the telescopic part 3 29 drives the transmission rod 28 to slide downward a distance L3. At this time, the transmission rod 28 will drive the sliding rod 21 to compress the return spring 27 and slide down together, breaking away from the limit of the sliding rod 21 on the disc 30. Moreover, since the bottom surface of the sliding frame 20 and the top surface of the transmission rod 28 are both inclined surfaces, after the transmission rod 28 slides down, the top surface of the transmission rod 28 is butted against the bottom surface of the sliding frame 20, so that the disc 30 slides along the top surface of the transmission rod 28 after being welded to the vertical rod 31, thereby realizing the transportation of the vertical rod 31 after welding is completed.
