Description

Technical Field

[0001] The invention relates to the technical field of welding and fixing, and in particular to a long-axis steel component welding device. Background Art

[0002] Long-axis steel components have important applications in steel structure engineering. The steel has high tensile and compressive strength, and takes into account both lightweight and load-bearing capacity. The cylinder is an important equipment commonly used in engineering machinery, metallurgy, mining and other fields. It is retracted and extended through hydraulics to provide sufficient thrust and tension. The piston rod of the cylinder is a long-axis steel component. During the production and processing of the cylinder, earrings need to be welded at the end of the piston rod for hook connection.

[0003] The existing long-axis steel structure welding device generally directly clamps one end of the piston rod to the fixed column through the clamping claw plate, and then installs the earring on the other end of the piston rod, rotates the piston rod, and welds the connection. However, the piston rod has a certain length and a certain weight. It is very troublesome and laborious to directly clamp it and install it on the clamping claw plate, which reduces the welding efficiency. In addition, simply clamping and positioning it by the clamping claw plate can easily cause the piston rod to tilt downward, causing the axis to offset from the rotating shaft of the clamping claw plate, resulting in a decrease in welding accuracy and reduced weld strength, which affects the later stability and safety of the cylinder equipment. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a long-axis steel structure welding device, which can help the clamping claw plate to horizontally support the piston rod, prevent the piston rod axis from shifting, improve welding accuracy, and conveniently arrange different models of piston rods at the axis of the clamping claw plate for clamping, positioning and welding.

The rotating shafts of the driving bevel gear 442 are respectively connected to the corresponding height adjustment screw 421, and the rotating shafts of the two driven bevel gears 443 are respectively connected to the telescopic tube 444 with keys.

[0039] In the above description, the piston rod 8 is placed horizontally on the two lifting support structures 42, and is horizontally arranged above the base 1 through two pairs of rotating wheels 425. The height adjustment screw 421 is rotated to make the two adjustment slides 422 slide relative to each other, and the diagonal support rod 423 flips, and the pair of rotating wheels 425 is supported. In the process, the height adjustment screw 421 of the other lifting support structure 42 is driven to rotate synchronously through the telescopic tube 444, so that the diagonal support rod 423 of the other lifting support structure 42 is flipped synchronously, and the other pair of rotating wheels 425 is supported to the same height, thereby achieving the effect of adjusting the axial arrangement height of the piston rod 8, and keeping the axial center of the piston rod 8 in a horizontal horizontal state along the left and right to prevent it from tilting and offsetting. When the distance between the two lifting support structures 42 changes, the telescopic tube 444 is extended and retracted to adjust its own length.

[0040] Combined with attachment Figure 8 , Attachment Figure 9 , Attachment Figure 10As shown, the manual positioning structure 43 includes a mounting box 431 and a U-shaped frame 438 arranged below the sliding seat 41. The U-shaped frame 438 is arranged with its opening facing forward, and the rear side is connected to the transmission plate 45. An adjusting screw 437 is provided on the inside. A worm gear 432 and a worm 433 that are meshed with each other are rotatably provided in the mounting box 431. The worm gear 432 is threadedly sleeved on the positioning screw 437, and a driven gear 434 is provided on the top of the worm 433.

[0041] Combined with attachment Figure 2 , Attachment Figure 3 , Attachment Figure 11 As shown, the quick arrangement module 7 includes a scissor-type telescopic rod 73 and a driving screw 71. The driving screw 71 is arranged horizontally left and right, and one end is rotatably set on the base 1, and the other end is connected to the driving shaft of the driving motor 72 set on the base 1, and the positioning plate 65 of the top module 6 is provided with a threaded sleeve that threadably cooperates with the driving screw 71, a connecting rod 1 651 is uprightly set on the positioning plate 65, a connecting rod 3 451 is set on the transmission plate 45, and a connecting rod 2 74 is provided at the bottom of the base 1 (the connecting rod 1 651, the connecting rod 3 451 and the connecting rod 2 74 are arranged on the same straight line in the left and right directions), and the two ends of the scissor-type telescopic rod 73 are respectively rotatably set on the connecting rod 1 651 and the connecting rod 2 74, and the corresponding intersection is rotatably set on the connecting rod 3 451.

[0042] In the above description, after starting the driving motor 72, the positioning plate 65 drives the top module 6 to move along the horizontal slide 11, and at the same time compresses the scissor-type telescopic rod 73, so that the two sliding seats 41 move along the horizontal slide 11. During the process, the distance between the two sliding seats 41 and the distance between the top module 6 and the sliding seat 41 are reduced proportionally at the same time to prevent the distance between the components from being too large, so as to facilitate the support and arrangement of piston rods 8 of different lengths. Because some piston rods 8 are affected by the use method, etc., there are parts welded on the side wall, which may overlap with the adjustment support module 4 adjusted by the quick arrangement module 7, resulting in affecting the rotation of the piston rod 8. Manually rotate the corresponding adjustment rod 436. After gear transmission, the worm gear 432 is controlled to rotate, and the installation box 431 is driven to move on the adjustment screw 437, thereby driving the corresponding sliding seat 41 to slide, adjust its own position, and avoid the welding parts on the piston rod 8 to avoid affecting the rotation and horizontal support of the piston rod 8. Through the rapid arrangement of the module 7 and the manual adjustment structure 43, the sliding seat 41 is fixed after adjustment on the horizontal slide groove 11 to prevent side slippage when the piston rod 8 is arranged (one end of the piston rod 8 is lifted and the other end is in contact with the lifting support structure 42), and one end of the piston rod 8 slides down and causes damage and danger, thereby improving the stability and reliability of the support of the lifting support structure 42.

Through the spring 537 and the centering gear 536, the two pairs of centering rods 534 move relative to each other up and down for centering clamping, and one of the pairs of centering rods 534 abuts against the piston rod 8. The height of the supported piston rod 8 is adjusted by the lifting support structure 42 until the two pairs of centering rods 534 respectively abut against the upper and lower sides of the piston rod 8. At this time, the axis of the piston rod 8 is arranged horizontally and the height is the same as the axis height of the clamping claw plate 32, that is, the axis of the piston rod 8 coincides with the axis of the clamping claw plate 32. The two pairs of centering rods 534 are flipped to remove the centering height setting module 53, and after starting welding, the welding position is observed through the protective mirror 52.
