[0002] In the existing technology, welding equipment is ubiquitous in daily life. It is used in the installation of petrochemical pipelines. During the use of welding equipment, the operator usually holds and supports the welding equipment by hand. Since the pipes to be welded often vary in size, the operator needs to hold and support the welding equipment for a long time when welding larger pipes. This can easily cause soreness in the operator's arms, increase the operator's workload, and seriously affect the convenience of the welding equipment for pipe welding. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies. Common welding devices used in petrochemical pipeline installation are typically hand-held and supported by operators. When welding larger pipelines, operators need to hold the welding device for an extended period, increasing their workload and severely impacting the ease of pipeline welding. This invention provides a new welding device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a welding device, comprising: a device body, a connecting mechanism provided on one side of the device body, the connecting mechanism including a connecting block fixedly connected to one side of the device body, a connecting seat provided on one side of the connecting block, a collar fixedly connected to one side of the connecting seat, a fixing ring movably sleeved on the inner wall of the collar through a first bearing, a fixing mechanism provided on one side of the fixing ring, the fixing mechanism including a clamping plate provided on one side of the fixing ring, an adjusting frame fixedly connected to one side of the clamping plate, an adjusting bolt movably connected to the other side of the fixing ring through a second bearing, an anti-slip pad adhered to one side of the clamping plate, a fixing frame slidably passing through one side of the connecting block, a fixing bolt movably connected to one side of the fixing frame through a third bearing, a sliding rod fixedly connected to one side of the connecting block, a spring sleeved on the outer surface of the sliding rod, a limit block fixedly connected to one end of the sliding rod, and a positioning block fixedly connected inside the connecting seat.
[0005] In a preferred embodiment, one side of the connecting seat is provided with a slot adapted to the connecting block, one end of the connecting block is provided with a positioning groove adapted to the positioning block, and one end of the connecting block is provided with a fixing groove adapted to the fixing frame.
[0006] In one preferred embodiment, one end of the slide rod slides through one side of the fixed frame, and the other side of the fixed frame is provided with a limiting groove that matches the limiting block.
[0007] In a preferred embodiment, one end of the spring is welded to one side of the inner wall of the upper limit groove of the fixed frame, and the other end of the spring is welded to one side of the limit block.
[0008] In a preferred embodiment, one side of the connecting block has a threaded groove that matches the thread on the fixing bolt.
[0009] In a preferred embodiment, a sliding hole adapted to the adjusting frame is provided on one side of the fixing ring, and a threaded hole matching the thread on the adjusting bolt is provided on one side of the adjusting frame, and the outer surface of the anti-slip pad is in contact with the outer surface of the pipe.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0011] This invention, through the setting of a connecting mechanism and a fixing mechanism, selects an appropriate fixing ring according to the size of the pipe. The connecting block is inserted into the interior of the connecting seat, the fixing frame is pressed and moved, and the fixing bolt is rotated to fix the position of the fixing frame after movement. The fixing frame stably fixes the connecting block, providing a good and stable fixation measure for the connecting block inside the connecting seat, thereby improving the stability of the connection between the device body and the fixing ring. When the welding head of the device body corresponds to the welding position of the pipe, the adjusting bolt is rotated to drive the adjusting frame to move. The clamping plate and anti-slip pad are used to fix the fixing ring on the outer surface of the pipe, preventing the device body from shifting position and affecting the welding effect. The device body is dragged to move and weld on the outer surface of the pipe, and the collar rotates on the outer surface of the fixing ring. This avoids the need for operators to hold and support the device body for a long time during pipe welding, reducing the workload of operators and improving the convenience of pipe welding.

A fixing ring 24 is movably sleeved on the inner wall of 23 via a first bearing. A fixing mechanism 25 is provided on one side of the fixing ring 24. A fixing frame 26 slides through one side of the connecting block 21. A fixing bolt 27 is movably connected to one side of the fixing frame 26 via a third bearing. A sliding rod 28 is fixedly connected to one side of the connecting block 21. One end of the sliding rod 28 slides through one side of the fixing frame 26. A limiting groove adapted to the limiting block 210 is provided on the other side of the fixing frame 26. By providing the limiting groove, the limiting block 210 can move normally inside the fixing frame 26. A spring 29 is sleeved on the outer surface of the sliding rod 28. One end of the spring 29 is welded to one side of the inner wall of the limiting groove in the fixing frame 26, and the other end of the spring 29 is welded to one side of the limiting block 210. By providing the spring 29, the spring 29 provides sufficient elasticity, so that the fixing frame 26 can maintain a good positional stability with the help of the elasticity of the spring 29. One end of the sliding rod 28 is fixedly connected to the limiting block 210. A positioning block 211 is fixedly connected inside the connecting seat 22.
[0022] Example 2
[0023] like Figure 1As shown, the fixing mechanism 25 includes a clamping plate 251 disposed on one side of a fixing ring 24. An adjusting frame 252 is fixedly connected to one side of the clamping plate 251. An adjusting bolt 253 is movably connected to the other side of the fixing ring 24 via a second bearing. An anti-slip pad 254 is adhered to one side of the clamping plate 251. A sliding hole adapted to the adjusting frame 252 is opened on one side of the fixing ring 24. By opening the sliding hole, the adjusting frame 252 can move normally on the fixing ring 24. A threaded hole matching the thread on the adjusting bolt 253 is opened on one side of the adjusting frame 252. By opening the threaded hole, the adjusting frame 252 can move with the rotation of the adjusting bolt 253. The outer surface of the anti-slip pad 254 is in contact with the outer surface of the pipe. By setting the anti-slip pad 254, the anti-slip pad 254 provides a good anti-slip effect, so that the clamping plate 251 and the pipe have good anti-slip measures.
[0024] Working principle:
[0025] like Figure 1-4 As shown, during use, select the appropriate fixing ring 24 according to the size of the pipe. After selecting the fixing ring 24, connect the device body 1 to the collar 23 on the fixing ring 24. Insert the connecting block 21 connected to one side of the device body 1 into the connecting seat 22. As the connecting block 21 is inserted, the positioning block 211 gradually inserts into the connecting block 21 until the connecting block 21 can no longer be inserted into the connecting seat 22. Keep the position of the connecting block 21 still and slowly press the fixing frame 26 to move. During the movement of the fixing frame 26, the fixing bolt 27 moves and slides on the outer surface of the slide rod 28. The limiting block 210 moves inside the fixing frame 26. The spring 29 is affected by the pressing force, and its shape gradually changes until the fixing frame 26 is pressed and moved until the fixing bolt 27 contacts the connecting seat 22. Rotate the fixing bolt 27 to rotate, and the fixing bolt 27 gradually inserts into the connecting seat 22. The fixed frame 26 continues to move until the fixed bolt 27 can no longer be rotated. The connecting block 21 is connected and fixed inside the connecting seat 22 using the fixed frame 26. Another fixed ring 24 is connected to the other side of the device body 1. After the device body 1 is connected, the fixed ring 24 is fitted onto the outer surface of the pipe and dragged along the outer surface of the pipe until the welding head of the device body 1 corresponds to the position of the pipe to be welded. The adjusting bolt 253 is rotated. During the rotation of the adjusting bolt 253, the adjusting frame 252 is moved. During the movement of the adjusting frame 252, the clamping plate 251 is moved. The clamping plate 251 gradually moves closer to the pipe until the adjusting bolt 253 can no longer be rotated and the anti-slip pad 254 on the clamping plate 251 contacts the outer surface of the pipe. After the fixed ring 24 is fitted onto the outer surface of the pipe, the device body 1 is started to operate and the pipe is moved for welding.
