A smart pipe welding robot

Abstract

This invention belongs to the field of pipe welding technology, and particularly relates to an intelligent pipe welding robot to solve the technical problem of not being able to adjust the pipe welding speed. It includes a mounting bracket plate, a bracket transmission group, a power group, a clamping group, a drive group, and a welding group. The bracket transmission group is connected to the power group, the clamping group is connected to the bracket transmission group, the drive group is connected to the power group, the drive group is connected to the bracket transmission group, and the welding group is connected to the bracket transmission group. By rotating the mounting sleeve, the middle connecting column is driven to move, which in turn drives the first and second connecting frame frames to move. This causes a change in the mating position between the first and second connecting frame frames and the first mating wheel, and simultaneously changes the mating position between the second connecting frame frame and the second mating wheel. This, in turn, changes the rotational speed output by the transmission bevel gear three, thereby achieving adjustment of the pipe welding speed.

[0014] The advantages of this invention are:

[0015] 1. Start the actuator motor, which drives the rotating bracket one to rotate. This, in turn, drives the connecting frame one through the mating wheel one and the connecting frame one, and through the middle connecting column, drives the connecting frame two to move. This, in turn, drives the rotating bracket two to rotate, which in turn drives the rotating disk one to move. This, in turn, drives the clutch disk one to rotate through the sliding mounting sleeve and the sliding column. This, in turn, drives the clutch disk two to rotate, which in turn drives the transmission bevel gear three to rotate, thus outputting power through the transmission bevel gear three. Simultaneously, manually rotate the rotating wheel, which drives the rotating screw to move. This, in turn, drives the rotating mounting sleeve to slide along the mounting bracket two, which in turn drives the middle connecting column to move. This, in turn, drives the connecting frame one and the connecting frame two to move, thus changing the mating position of the connecting frame one and the mating wheel one, and simultaneously changing the mating position of the connecting frame two and the mating wheel two. This, in turn, changes the rotational speed output by the transmission bevel gear three, thereby adjusting the pipe welding speed.

[0016] 2. As the central shaft rotates, it drives the connecting pulley to move, which in turn drives the connecting belt to move the connecting pulley, which in turn drives the sliding mounting sleeve and the clamping post to move. The clamping post then drives the pipe to be welded to rotate, thus achieving the welding of the pipe. At the same time, manually rotating the drive turntable drives the extrusion slide plate to move through the drive wedge column. The extrusion slide plate compresses the central push spring A, thereby changing the force exerted by the central push spring A on the clamping post, thus increasing the fixing stability of the clamping post on the pipe, and simultaneously achieving the fixing of pipes of different specifications.

[0017] 3. Slide slider one along the slide groove one, which drives the mating rotating rod one to move. The mating rotating rod one then drives the hinged sliding column, causing the transmission sleeve to switch between mating sleeve one and mating sleeve two. This allows the middle rotating shaft one to rotate clockwise or counterclockwise, thereby adjusting the direction of pipe rotation welding. 4. Start the actuator motor two, which drives the middle rotating column to rotate. The middle rotating column then drives the middle sliding plate to slide along the rectangular slide groove. The middle sliding plate then drives the welding torch to move. Through the contact between the welding torch and the pipe, the pipe is welded. At the same time, the welding length of the welding torch is adjusted by the middle sliding plate sliding along the rectangular slide groove. Attached Figure Description

[0061] like Figure 23-25As shown, the welding assembly 5 includes a welding bracket 5-1, a welding connecting sleeve 5-2, an upper end cover 5-3, a second actuator motor 5-4, a middle rotating column 5-5, a middle sliding plate 5-6, a welding torch 5-7, and a rectangular slide groove 5-8. The welding bracket 5-1 is fixedly mounted on the mounting base plate 1-1. The welding connecting sleeve 5-2 is fixedly mounted on the welding bracket 5-1. The upper end cover 5-3 is fixedly mounted on the welding connecting sleeve 5-2. The middle rotating column 5-5 is rotatably mounted on the upper end cover 5-3. The second actuator motor 5-4 is mounted on the upper end cover 5-3. The output shaft of the second actuator motor 5-4 is mounted on the middle rotating column 5-5. The middle rotating column 5-5 and the middle sliding plate 5-6 are threaded together. Next, the middle sliding plate 5-6 is slidably installed in the rectangular slide groove 5-8, which is located at the inner end of the welding connection sleeve 5-2. The welding torch 5-7 is fixedly installed on the middle sliding plate 5-6. With this setup, when the actuator motor 5-4 is started, the middle rotating column 5-5 is rotated, which in turn drives the middle sliding plate 5-6 to slide along the rectangular slide groove 5-8. The middle sliding plate 5-6 then drives the welding torch 5-7 to move. Through the contact between the welding torch 5-7 and the pipe, the pipe is welded. At the same time, the welding length of the welding torch 5-7 can be adjusted by the middle sliding plate 5-6 sliding along the rectangular slide groove 5-8.
