Description

Technical Field

[0001] The present application relates to the technical field of tower pipe welding, and in particular to an auxiliary welding device for butt-jointing tower pipes. Background Art

[0002] Tower pipe welding is an important industrial processing technology. In the construction of the tower, pipes play a key supporting and connecting role. Tower pipe welding mainly uses specific welding technology to connect pipes of different shapes and specifications to form a solid tower structure. During the processing, professional welders will choose appropriate welding methods according to design requirements, such as manual arc welding, gas shielded welding, etc. First, pre-treat the pipes, including cutting and grinding, to ensure the cleanliness and flatness of the welding parts. Then, perform welding operations accurately to make the connection between the pipes tight and firm, and able to withstand the test of various natural environments and external forces. After welding, the pipes also need to undergo strict quality inspection to ensure the safety and stability of the tower. Tower pipe welding is crucial to the infrastructure construction in the fields of power transmission and communication. The welding auxiliary device in the prior art has certain limitations during use. Specifically, the user needs to rotate the push stud to drive the push ring frame to move, so that the fixed ring on the push ring frame can move up and down to adapt to tubular workpieces of different sizes. Then, the tubular workpiece is placed between the two sets of fixed rings. At this time, the fixed ring will expand outward under the action of the workpiece, and the push spring will deform and generate a reaction force, thereby pushing the clamped workpiece. Similarly, another tubular workpiece is placed between the two sets of fixed rings in another set of auxiliary cylinders, so that the ends of the two sets of tubular workpieces are fitted together and ready for welding. During welding, the double-headed brake motor is turned on, and the two sets of auxiliary cylinders are driven to rotate synchronously through the transmission shaft, transmission gear and transmission gear ring, thereby causing the two sets of tubular workpieces to rotate synchronously to expand the welding surface and weld them together; However, the above-mentioned equipment has many defects during actual application. First, after clamping the pipe fittings, the position of the pipe fittings cannot be further flexibly adjusted, especially when the lateral welding position needs to be adjusted, it is obviously impossible to achieve lateral displacement of the pipe rack. Secondly, its application process mainly relies on manual adjustment to clamp the pipe fittings. During use, it is necessary to manually adjust the clamps on both sides to assist in clamping. This method cannot quickly achieve automatic and precise clamping in overall operation, and during use, manual adjustment is prone to docking defects. At the same time, the overall design that requires manual adjustment of the two sets of clamps to clamp leads to low work efficiency and is easy to affect production and processing efficiency during use. In summary, the welding auxiliary device urgently needs to be improved and optimized to improve its performance and practicality. Summary of the invention

[0024] Principle of use and advantages: By carefully setting the power mechanism 600 and the clamping mechanism 700, the device exhibits excellent performance during actual application. First, when using the device, it is only necessary to insert the required welded pipe into the inner side of the annular frame 710, and then place the pipe on the two guide blocks 732 at the bottom. Then, by starting the third brake motor 633, the third brake motor 633 drives the screw rod 632 on the inner side of the side plate 631 to rotate. Since the threads at both ends of the screw rod 632 rotate in opposite directions, it can drive the sleeves at both ends of the screw rod 632 to slide back and forth on the screw rod 632. At this time, the screw rod 632 can drive the slider 641 to move inward or outward. During the displacement of the slider 641, the slider 641 can drive the transverse sliding track 642 to reciprocate and move. During the movement and displacement of the transverse sliding track 642, the linkage block 643 inside the transverse sliding track 642 and the slide plate 731 of the transmission clamp 730 rotate and connect. Then, during this period, the horizontal sliding track 642 drives the linkage block 643 to slide, and the sliding of the linkage block 643 can drive the slide plate 731 to slide. Since the slide plate 731 slides on the inner side of the side sliding track 720, after being guided by the side sliding track 720, the slide plate 641 can only move along the extension direction of the side sliding track 720. At this time, the linkage block 643 is resisted and adaptively slides on the inner side of the horizontal sliding track 642 for position compensation. It can be seen that during use, the device can start the third brake motor 633 to drive all the slide plates 731 on both sides of the mounting platform to slide synchronously on the inner side of the side sliding track 720. Since each side sliding track 720 is arranged in a cross shape, the sliding of the slide plate 731 can synchronously drive all the guide blocks 732 to move inward. At this time, the four guide blocks 732 can be clamped on the peripheral side of the pipe fitting at equal intervals. The synchronous and adjustable extension design of the slide plate 731 enables the device to more accurately and flexibly center and clamp pipe fittings of different sizes. During the overall operation of the pipe fitting, it is only necessary to start the third brake motor 633. On the one hand, the device has a more accurate positioning system, which can better center the butted pipe fittings and greatly improve the accuracy of the welding process; on the other hand, the various linkage components of the device can be quickly linked, so that only the forward and reverse rotation of the third brake motor 633 can drive each transmission clamp 730 to stably clamp the positioning pipe fittings of different sizes. No manual adjustment is required during the overall processing, so that the welding process is more accurate and efficient. The device adopts the combination of the clamping mechanism 700 and the driving mechanism 300, so that the device performs well during use. After the positioning and clamping of the pipe fitting is completed, if the lateral displacement of the pipe fitting to be welded needs to be adjusted, the electric push rod 310 can be started to operate, and the electric push rod 310 on the inner side of the installation groove can push the first brake motor 330 to move upward, and the upward movement of the first brake motor 330 can drive the driving roller 343 to move upward. During this period, the driving roller 343 is driven to rotate by starting the first brake motor 330, and the driving roller 343 and the pipe fitting are in a vertical state. By continuing to start the electric push rod 310, the driving roller 343 can be caused to contact the bottom of the pipe fitting, and the driving roller 343 can be driven to rotate by starting the second brake motor 342. At this time, the driving roller 343 can be rotated. The pipe fitting is driven to move laterally. Since the pipe fitting is located on the inner side of the transmission ball 733 in the guide block 732 as a whole, the pipe fitting can be stably moved laterally on the inner side of the annular frame 710 through the rotational guidance of the transmission ball 733. When the weld is ensured to correspond to the welding head position of the welding machine, the electric push rod 310 can be moved back, and the driving roller 343 leaves the bottom of the pipe fitting. The driving roller 343 is reset by starting the first brake motor 330. The driving roller 343 and the pipe fitting are arranged in parallel. The electric push rod 310 is started to push the driving roller 343 and the bottom of the pipe fitting to fit and connect. At this time, the second brake motor 342 is started again to run, and the pipe fitting can be driven to rotate on the inner side of the transmission ball 733 by the driving roller 343 fitting in contact with the bottom of the pipe fitting, so that the pipe fitting can rotate 360 ​​degrees. It can be rotated arbitrarily, so that the weld can be stably welded 360 degrees. It can be seen that during the overall welding process of the device, the electric push rod 310, the first brake motor 330 and the second brake motor 342 are used to adjust the rotation direction of the drive roller 343. At the same time, the transmission guide of the transmission ball 733 on the inner side of the guide block 732 can be used to enable the pipe fittings required for welding to be arbitrarily displaced laterally and rotated arbitrarily. It can be stably welded 360 degrees, and the weld can be quickly adjusted and the material can be automatically loaded and unloaded. The overall production and processing efficiency is more efficient. During specific application, the welding machine mounting plate 500 can be used to install the welding machine in conjunction with the mounting hole 900. The welding machine is a conventional technical means in the prior art, so it will not be described here.
