Description

Technical Field

[0001] This utility model relates to the field of welding technology, and more specifically, to a swing-type rotary welding machine. Background Technology

[0002] In modern industrial production, welding is one of the key processes to ensure product quality. Its application ranges from the manufacturing of small parts to large equipment. However, welding operations in workshops still mainly rely on manual operation. Each operator needs to carry and manage multiple devices and cables at the same time. This not only increases the labor intensity of workers, but also reduces the efficiency of operation. Especially when welding is required at multiple points at the same time, it is often necessary to allocate multiple workers to work at the same time, which greatly increases labor costs and management difficulty.

[0003] In actual production environments, due to the dense layout of workshop equipment, the laying of various cables and air pipes has become a major challenge. When operators move equipment, they not only need to avoid other equipment and personnel, but also need to prevent cables from getting tangled and damaged. This cumbersome cable management not only affects the normal progress of welding work, but also brings safety hazards and efficiency losses to the work of other trades, seriously restricting the improvement of overall production efficiency.

[0034] Each of the multiple sets of screws 12 is provided with a limiting rod 33 at its top.

[0035] The cable tie sleeve 10 is provided with a limiting plate 34. There are two sets of limiting plates 34, which are slidably connected to both sides of multiple sets of cable tie plates. The two sets of limiting plates 34 provide bidirectional guidance for the cable tie plates to ensure the accuracy of their movement trajectory.

[0036] Multiple sets of support rods 22 are equipped with stop blocks 35 on their outer walls, and the top surface of the lock sleeve 21 is provided with compression springs 36. Multiple sets of compression springs 36 are provided, and the top of multiple sets of limit blocks 19 are connected to the outer wall of the transmission sleeve 17 with reset springs 37. The combined action of the stop blocks 35, compression springs 36 and reset springs 37 realizes the automatic reset function of the locking mechanism.

[0037] In this embodiment, the cylinder 7 is operated so that its telescopic end pushes the large rack 6 to slide along the sliding sleeve 5 and mesh with the large gear 8, causing the large gear 8 to drive the swing frame 4 to rotate. By extending and retracting the telescopic end of the cylinder 7, the large rack 6 and the large gear 8 are driven to rotate clockwise or counterclockwise. The large rack 6 drives the swing frame 4 and the welding torch 29 to swing left and right, working in different directions. The wire harness mechanism can be set at different positions in the overall device according to the actual use, and clamping is performed according to the position of the air pipe 30. The air tube 30 is placed inside the cable harness sleeve 10. The sliding transmission sleeve 17 drives multiple sets of small racks 18 and multiple sets of small gears 16 to mesh and transmit power. The multiple sets of small gears 16 drive multiple sets of limiting rods 33 to rotate. The limiting rods 33 drive the screw 12 to rotate and engage with the screw sleeve 11. The screw 12 pushes the cable harness clamp 13 to slide along the two sets of limiting plates 34 through the push plate 15 to clamp the outer wall of the air tube 30. Multiple sets of soft pads 31 contact the air tube 30, and the transmission sleeve 17 is locked by the limiting mechanism.

[0038] More specifically, by having the top block 23 abut against the outer wall of the rotating sleeve 24, the support rod 22 supports the locking sleeve 21 to abut against the tops of multiple sets of limiting blocks 19, causing the bottom ends of the multiple sets of limiting blocks 19 to engage in the limiting grooves 20 and respectively compress the multiple sets of return springs 37, thus limiting the transmission sleeve 17. When unlocking is required, rotating the rotating sleeve 24 drives the multiple sets of clearance grooves 25 to move above the multiple sets of top blocks 23. At this time, the multiple sets of top blocks 23 disengage from the top surface of the rotating sleeve 24, pushing the locking sleeve 21 to release its abutment against the multiple sets of limiting blocks 19, and simultaneously pushing the multiple sets of support rods 22 to move in the clearance grooves. When multiple sets of stop blocks 35 pass through the clearance groove 25, the rotating sleeve 24 is rotated again to make the support rod 22 slide in the limiting groove 20 and compress the compression spring 36. At this time, the stop block 35 abuts against the outer wall of the rotating sleeve 24 to limit the locking sleeve 21. At this time, the transmission sleeve 17 is in a continuously unlocked state. When the rotating sleeve 24 is rotated again to make multiple sets of support rods 22 move into the clearance groove, the multiple sets of compression springs 36 elastically reset and push the locking sleeve 21 to abut against the top of multiple sets of limiting blocks 19, so that the multiple sets of limiting blocks 19 are locked in the limiting groove 20 again to limit the transmission sleeve 17.

[0039] In summary, during use or operation of the overall equipment: The cylinder 7 is operated so that its telescopic end pushes the large rack 6 to slide along the sliding sleeve 5 and mesh with the large gear 8, causing the large gear 8 to drive the swing frame 4 to rotate. The telescopic extension and retraction of the cylinder 7 drives the large rack 6 and the large gear 8 to rotate clockwise or counterclockwise. The large rack 6 drives the swing frame 4 and the welding torch 29 to swing left and right, working in different directions. The wire harness mechanism can be set at different positions in the overall device according to actual usage, depending on the position of the air pipe 30. The air tube 30 is clamped and placed inside the cable tie sleeve 10. The sliding transmission sleeve 17 drives multiple sets of small racks 18 and multiple sets of small gears 16 to mesh and drive. The multiple sets of small gears 16 drive multiple sets of limiting rods 33 to rotate. The limiting rods 33 drive the screw 12 to rotate and engage with the screw sleeve 11. The screw 12 pushes the cable tie clamp 13 to slide along the two sets of limiting plates 34 through the push plate 15 to clamp the outer wall of the air tube 30. Multiple sets of soft pads 31 contact the air tube 30, and the transmission sleeve 17 is locked by the limiting mechanism.

[0040] The top block 23 abuts against the outer wall of the rotating sleeve 24, causing the support rod 22 to support the locking sleeve 21 to abut against the tops of multiple sets of limiting blocks 19. This causes the bottom ends of the multiple sets of limiting blocks 19 to engage in the limiting grooves 20 and press against the multiple sets of return springs 37, thus limiting the transmission sleeve 17. When unlocking is required, rotating the rotating sleeve 24 moves the multiple sets of relief grooves 25 above the multiple sets of top blocks 23. At this time, the multiple sets of top blocks 23 disengage from the top surface of the rotating sleeve 24, pushing the locking sleeve 21 to release its contact with the multiple sets of limiting blocks 19. Simultaneously, it pushes the multiple sets of support rods 22 to move in the relief grooves 20. Within 5, when multiple sets of stop blocks 35 pass through the clearance groove 25, the rotating sleeve 24 is rotated again to make the support rod 22 slide in the limiting groove 20 and compress the compression spring 36. At this time, the stop block 35 abuts against the outer wall of the rotating sleeve 24 to limit the locking sleeve 21. At this time, the transmission sleeve 17 is in a continuously unlocked state. When the rotating sleeve 24 is rotated again to make multiple sets of support rods 22 move into the clearance groove, the multiple sets of compression springs 36 elastically reset and push the locking sleeve 21 to abut against the top of multiple sets of limiting blocks 19, so that the multiple sets of limiting blocks 19 are locked again in the limiting groove 20 to limit the transmission sleeve 17.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
