For the design positioning device and the positioning method for a welding operation platform, the first driving ring and the second driving ring are respectively used to push the first clamping arm assembly and the second clamping arm assembly simultaneously, so as to realize the quick clamping and positioning of the metal pipe fitting. Compared with the traditional clamping and positioning method using a clamping and positioning device, the positioning process of the design positioning device for the welding operation platform is more convenient and fast, which is beneficial to improving the welding speed of the metal pipe fitting.

[0019] Beneficial effects

[0020] The present invention provides a design positioning device and a positioning method for a welding operation platform. Compared with the prior art, the following beneficial effects are achieved:

[0021] 1. A design positioning device and a positioning method for a welding operation platform. A servo motor is fixedly connected to the bottom of the welding operation table. The output shaft of the servo motor rotates through the welding operation table and is fixedly connected to a bearing plate. A clamping device for steel pipe positioning is fixedly connected to the top of the bearing plate. The clamping device includes a first clamping mechanism and a second clamping mechanism respectively fixedly connected to the left and right sides of the top of the bearing plate. A welding mechanism for welding metal pipe fittings is fixedly connected to the top of the second clamping mechanism. A plurality of arc-shaped through grooves are evenly formed in the top of the welding operation table. A driving component for controlling the clamping force of the first clamping mechanism and the second clamping mechanism is slidably arranged inside the plurality of arc-shaped through grooves. Cylinders for controlling the height of the driving component are fixedly connected to the outer walls on both sides of the welding operation table. A power mechanism for driving the first clamping mechanism to rotate is arranged on the top of the base. The power mechanism includes a support arm and a second bevel gear ring. The two support arms are respectively fixedly connected to both sides of the top of the base. The second bevel gear ring is fixedly connected between the opposite side walls of the two support arms, solving the problem that after welding one side of the pipe fitting, it is necessary to repeatedly flip the pipe fitting multiple times to achieve full welding of the butt joint position. During the process of flipping the pipe fitting, it is necessary to repeatedly perform the operation steps of releasing positioning - flipping - positioning - welding on the pipe fitting, which not only results in low welding efficiency but also increases the labor intensity of the welding workers.

[0022] 2. A design positioning device and a positioning method for a welding operation platform. By setting a clamping device and a driving component for driving the clamping device to clamp, the third inclined surface on the ring can be used to push the first wedge block and the second wedge block to move, so that the first driving ring and the second driving ring respectively push the first clamping arm assembly and the second clamping arm assembly at the same time, realizing quick clamping and positioning of the metal pipe fitting. Compared with the traditional clamping and positioning method using a clamping and positioning device, the positioning process of this design positioning device for the welding operation platform is more convenient and fast, which is beneficial to improving the welding speed of the metal pipe fitting and the welding efficiency.

[0023] 3. A design positioning device and a positioning method for a welding operation platform. The rotation of the first bearing ring in the first clamping mechanism is realized by the meshing transmission of the first bevel gear ring and the second bevel gear ring. It can be linked with the second bevel gear ring while the first clamping mechanism rotates, so that the metal pipe fitting in the welding state can be flipped 360 degrees. Without repeatedly disassembling and clamping the metal pipe fitting, continuous welding operation of the metal pipe fitting can be realized. At the same time, there is no need to separately set a driving device for the rotation of the first bearing ring, saving the cost of setting the driving device, and making the structure of this design positioning device for the welding operation platform simpler, facilitating subsequent maintenance and repair work.

[0024] 4. A design positioning device and positioning method for a welding operation platform. By setting the first clamping arm assembly and the second clamping arm assembly with the same structure, the characteristic that the lifting rod can freely lift within a certain range inside the cylinder is utilized, enabling the clamping arm assembly to have the ability to clamp metal pipe fittings with different outer diameters. When clamping a metal pipe fitting with a larger outer diameter, the lifting rod retracts into the inside of the cylinder, thereby increasing the distance between multiple arc-shaped clamping pieces to be suitable for clamping metal pipe fittings with a larger outer diameter. When clamping a metal pipe fitting with a smaller outer diameter, the first spring pushes the lifting rod away from the cylinder, causing multiple arc-shaped clamping pieces to approach each other, so as to be able to clamp metal pipe fittings with a smaller outer diameter.

The ball 5143 is slidably connected to the inner wall of the first driving ring 523.,

[0044] The embodiment of the present invention also provides a positioning method for a positioning device of a welding operation platform, and the specific method includes the following steps:

[0045] Step 1. Clamp the pipe fittings: First, pass one of the metal pipe fittings through the inner cavity of the first clamping and regulating component 52 and insert it into the first clamping component 51, that is, the metal pipe fitting passes through the first driving ring 523 and the first bearing ring 511 and extends to the outside of the first bearing ring 511. The other metal pipe fitting passes through the second clamping and regulating component 62 and is inserted into the second clamping component 61, that is, the metal pipe fitting passes through the second driving ring 623 and the second bearing ring 611 and extends to the outside. The ends of the two metal pipe fittings to be welded approach each other, and the welding position is directly below the welding mechanism 7. Then, start the cylinder 10 to pull the driving component 9 downward. The guiding block 93 slides downward along the inner wall of the arc-shaped through groove 8, and the third inclined surface 92 pushes the first wedge block 527 towards the first regulating box 521. The driving component 9 simultaneously drives the first clamping mechanism 5 and the second clamping mechanism 6 to work. The first push rod 526 then pushes the first T-shaped slider 522 and the first driving ring 523 to move synchronously towards the first bearing ring 511. Multiple first clamping arm assemblies 514 are pushed by the first inclined surface 524 and simultaneously approach the center position of the first bearing ring 511 along the inner wall of the first through hole 513. The metal pipe fitting is fixed in position by a plurality of arc-shaped clamping pieces 5145 evenly distributed. For metal pipe fittings with a larger diameter, when the driving component 9 moves downward, due to the larger size of the metal pipe fitting and the same downward movement distance of the driving component 9, the lifting rod 5144 is pushed by the metal pipe fitting and slides upward along the inner wall of the cylinder body 5141, and the first spring 5146 is compressed. Similarly, the third inclined surface 92 moves downward and pushes the second wedge block 627 towards the second regulating box 621, so that the second push rod 626 pushes the second T-shaped slider 622 to slide along the second T-shaped groove against the elastic force of the fourth spring 625. The second inclined surface 624 simultaneously pushes a plurality of second clamping arm assemblies 613 to clamp the metal pipe fitting, and the two metal pipes are stably clamped;

[0046] Step 2. Weld the pipe fittings: First, start the welding mechanism 7 to weld one side of the two metal pipe fittings. By using the electric telescopic rod 73 to lift or push down the electric telescopic rod 73, the welding torch 72 is made to fit the joint position of the two metal pipe fittings to meet the welding requirements. Then, start the servo motor 3 to drive the bearing plate 4 to rotate. Since the first clamping mechanism 5 is driven by the second bevel gear ring 12, that is, the first bevel gear ring 512 and the second bevel gear ring 12 are meshed and connected, the first clamping mechanism 5 can rotate around its own axis while revolving around the welding operation table 2. While the first clamping mechanism 5 rotates around the top of the welding operation table 2, and since the two metal pipe fittings have been welded and fixed in Step 1, therefore, the two metal pipe fittings inside the first clamping mechanism 5 and the second clamping mechanism 6 rotate around their own axes, and the welding mechanism 7 simultaneously welds the joint position during the rotation of the metal pipe fittings. After the bearing plate 4 rotates 360 degrees, the all-round welding of the joint position of the two metal pipe fittings is completed;

[0047] Step 3. Remove the pipe fitting: After welding is completed, start the cylinder 10 again to push the driving assembly 9 upward, release the clamping of the metal pipe fitting by the first clamping mechanism 5 and the second clamping mechanism 6. The second wedge block 627 and the first wedge block 527 lose the push of the driving assembly 9. The first push rod 526 and the second push rod 626 are respectively pushed by the third spring 525 and the fourth spring 625 to move towards each other. The second clamping arm assembly 613 and the first clamping arm assembly 514 lose the driving force and release the clamping of the metal pipe fitting, and then the metal pipe fitting can be taken out.
