Description

Technical Field

[0001] This invention relates to the field of welding auxiliary devices, and in particular to a floating adjustment rotary device for circumferential welding of pipe cylinders. Background Technology

[0002] Circumferential welding technology is widely used in the welding of various round or cylindrical components, such as pipe cylinder welding in industries such as petrochemicals, pressure vessels, and pipeline engineering.

[0003] When performing circumferential welding on a pipe cylinder, it needs to be placed on a dedicated rotary support positioning device for welding, such as the rotary cylinder circumferential weld automatic welding device with application number CN202211298634.0. Simultaneously, before welding, to ensure the welding effect of the pipe cylinder, its relative position in the horizontal and vertical directions on the rotary device needs to be adjusted. However, existing methods for adjusting this position mostly rely on manual labor and related auxiliary tools, which presents the following problems: Due to the large size and weight of the pipe cylinder, the adjustment process is difficult when using manual labor and related auxiliary tools to adjust the alignment position of the pipe cylinder. The adjustment range is also difficult to control, either too large or too small, which leads to deviations in the alignment position of the pipe cylinder after adjustment, affecting the subsequent circumferential weld effect.

[0026] As per the instruction manual Figure 8As shown, the first clamping assembly 363 and the second clamping assembly 364 used for clamping the pipe cylinder have the same structure. Both include a transverse motor assembly 3631, a transverse lead screw 3632, a transverse slide rail 3633, a transverse drive seat 3634, a clamping frame 3635, and a clamping block 3636.

During installation, the transverse lead screw 3632 is mounted within the transverse frame 362 via bearings, and the transverse motor assembly 3631 is connected to the end of the transverse lead screw 3632.

It should be noted that the specific installation position of the clamping block 3636 inside the clamping frame 3635 is determined according to the specific needs of the pipe body.

[0027] As per the instruction manual Figure 9 As shown, the floating adjustment mechanism 365 for laterally floating adjustment after clamping the pipe cylinder includes a bottom mounting frame 3651, a mounting platform 3652, a limiting bracket 3653, a floating slide rail 3654, a floating slider 3655, and a floating seat 3656; wherein, the bottom mounting frame 3651, which supports the mounting platform 3652, is installed in the middle of the transverse frame 362, and the mounting platform 3652 is mounted and connected on the bottom mounting frame 3651. The mounting platform 3652 is...

The floating slider 3655 is slidably engaged with the floating slide rail 3654. A floating seat 3656 for placing the pipe cylinder is mounted and connected on the floating slider 3655. At the same time, limit brackets 3653 are fixedly installed at the four upper corners of the mounting platform 3652, and buffers for cushioning the floating seat 3656 are installed on the limit brackets 3653.

[0028] The working process of the floating adjustment rotary device for circumferential welding of pipe cylinder according to the present invention is as follows: Step 1: Opening the opening and closing port: First, the controllable gear ring opening and closing drive assembly 37 opens the opening and closing gear ring 332. Specifically, the locking mechanism 334 on the gear ring body 331 first releases the locking of the opening and closing gear ring 332, and then controls the electric cylinder 372 to work. The electric cylinder 372 drives the drive rod 373 to retract. During the retraction of the drive rod 373, it drives the swing arm body 371 and the roller assembly on it to rise in the wheel grooves 335 on both sides of the opening and closing gear ring 332. At this time, under the drive of the swing arm body 371 and the roller assembly, the opening and closing gear ring 332 opens the opening and closing port on the upper part of the gear ring body 331. Step 2: Unloading: The operator can use the external hoisting mechanism to put the pipe cylinder into the floating seat 3656 of the floating adjustment clamping assembly 36 inside the toothed ring body 331 through the opening and closing position of the upper part of the toothed ring body 331. At the same time, the operator controls the first clamping member 363 and the second clamping member 364 in the floating adjustment clamping assembly 36 to work. The first clamping member 363 and the second clamping member 364 work together to clamp the pipe cylinder on the floating seat 3656. Step 3: Clamping: The structure and working principle of the first clamping assembly 363 and the second clamping assembly 364 are the same. Specifically, the transverse motor group 3631 in the first clamping assembly 363 and the second clamping assembly 364 can be started. The transverse motor group 3631 drives the transverse lead screw 3632 to rotate in the positive direction. At this time, under the action of the threaded pushing force, the transverse threaded sleeve on the transverse lead screw 3632 drives the transverse drive seat 3634 to move. The transverse drive seat 3634 drives the clamping frame 3635 together with the clamping block 3636 to move towards the pipe cylinder. When the clamping block 3636 in the first clamping assembly 363 and the second clamping assembly 364 clamps the pipe cylinder, the transverse motor group 3631 stops working, and the clamping action of the pipe cylinder is completed. Step 4: Height and Orientation Floating Adjustment: The operator can control the start of the lifting motor group 341 in the left lifting adjustment component 34 and the right lifting adjustment component 35. The lifting motor group 341 drives the lifting screw 343 to rotate. At this time, under the action of the threaded pushing force, the lifting threaded sleeve drives the lifting drive seat 345 to achieve lifting adjustment. When lifting and adjusting, the lifting drive seat 345 will drive the transverse frame 362 and its first clamping part 363, second clamping part 364, floating adjustment mechanism 365 and pipe cylinder to lift and adjust through the connecting bracket 361 until the height of the pipe cylinder to be welded is consistent. Step 5: Horizontal Orientation Adjustment: When the pipe body to be welded deviates in the horizontal orientation, the operator can adjust the horizontal displacement by adjusting the first clamping assembly 363, the second clamping assembly 364, and the clamped pipe body together. This can be done in two ways: Scenario 1: The transverse motor units 3631 in the first clamping assembly 363 and the second clamping assembly 364 can be started synchronously. The transverse motor unit 3631 in the first clamping assembly 363 needs to drive the transverse lead screw 3632 to rotate clockwise, and the transverse motor unit 3631 in the second clamping assembly 364 needs to drive the transverse lead screw 3632 to rotate counterclockwise. In this state, the transverse threaded sleeve in the first clamping assembly 363 will drive the transverse drive seat 3634 together with the clamping frame 3635, the clamping block 3636, and the pipe cylinder. The pipe moves towards the second clamping assembly 364. At the same time, the transverse threaded sleeve in the second clamping assembly 364 will drive the transverse drive seat 3634, together with the clamping frame 3635, the clamping block 3636, and the pipe cylinder, to move backward in the direction of the second clamping assembly 364 to ensure that the first clamping assembly 363 and the second clamping assembly 364 are always clamped to the pipe cylinder. During the above process, the pipe cylinder on the floating seat 3656 will drive the floating slider 3655 to achieve driven displacement adjustment on the floating slide rail 3654. Scenario 2: The transverse motor assembly 3631 in the first clamping assembly 363 and the second clamping assembly 364 can be started synchronously. The transverse motor assembly 3631 in the first clamping assembly 363 needs to drive the transverse lead screw 3632 to rotate counterclockwise, and the transverse motor assembly 3631 in the second clamping assembly 364 needs to drive the transverse lead screw 3632 to rotate clockwise. In this state, the transverse threaded sleeve in the first clamping assembly 363 will drive the transverse drive seat 3634 together with the clamping frame 3635 and the clamping block 3636. The pipe cylinder moves backward, and at the same time, the transverse threaded sleeve in the second clamping assembly 364 will drive the transverse drive seat 3634 together with the clamping frame 3635, clamping block 3636 and pipe cylinder to move towards the first clamping assembly 363, so as to ensure that the first clamping assembly 363 and the second clamping assembly 364 are always clamped to the pipe cylinder. During the above process, the pipe cylinder on the floating seat 3656 will drive the floating slider 3655 to achieve driven displacement adjustment on the floating slide rail 3654. Step Six: Rotation: After the gear ring opening and closing drive assembly 37 drives the opening and closing gear ring 332 to close the opening and closing port on the upper part of the gear ring body 331, the operator can control the rotary drive motor 321 in the rotary drive assembly 32 to start. The rotary drive motor 321 drives the drive gear 322 to rotate. At this time, the rotary gear ring structure rotates within the mounting housing 31 under the drive of the drive gear 322. At this time, the pipe cylinder inside the rotary gear ring structure rotates, and the circumferential welder can then perform circumferential weld on the joint of the pipe cylinder.
