Referring to fig. 1 to 5, a preferred structure of a pipeline spiral weld welding device provided by an embodiment of the present invention is shown. As shown in the figure, the pipeline spiral weld joint welding device is mainly used for welding pipelines with spiral weld joints. In particular, the pipe seam welding device may be disposed on the equipment support 10. Pipeline spiral weld welding set includes: the welding device comprises a rotating device 1, a control device 2, a position adjusting device 4, a detection device 3 and a welding gun 5. Wherein, the rotating device 1 is used for fixing and rotating the pipeline 9 to be welded with the spiral welding seam, so that the pipeline 9 to be welded can be in a rotating state in the welding process. The detection device 3 is used for detecting welding information of the pipe 9 to be welded, and the welding information may include: rotation information of the pipe 9 to be welded, such as a rotation speed, a rotation angle, etc., and weld information of the pipe 9 to be welded, such as a welding position, etc.
The position adjusting device 4 is connected with the welding gun 5, and the position adjusting device 4 is used for adjusting the position of the welding gun 5 so that the position of the welding gun 5 is matched with the position of the spiral welding seam of the pipeline 9 to be welded, and then the welding gun 5 is enabled to weld the spiral welding seam.
The control device 2 is connected with the detection device 3 and the position adjusting device 4, and the control device 2 is used for receiving the welding information detected by the detection device 3, determining a welding position according to the welding information, and controlling the position adjusting device 4 to move according to the determined welding position to adjust the position of the welding gun 5, so that the position of the welding gun 5 corresponds to the welding position, namely the position of the welding gun 5 corresponds to the position of the spiral welding seam.
Specifically, the position adjusting device 4 is fixedly connected to the welding gun 5, and the movement of the position adjusting device 4 drives the movement of the welding gun 5, so that the position of the welding gun 5 is adjusted.
In the embodiment, the detection device 3 detects the welding information of the pipeline to be welded 9, the control device 2 determines the welding position according to the welding information, and then controls the position adjusting device 4 to move to adjust the position of the welding gun 5, so that the position of the welding gun 5 is always matched with the position of the spiral weld of the pipeline to be welded 9, the deviation in the welding process can be corrected in real time, the welding quality is ensured, the welding yield and the welding efficiency are improved, the labor intensity of workers is reduced, and the problem that the welding quality of the spiral weld of the pipeline is poor in the prior art is solved.
Referring to fig. 1 to 7, in the above embodiment, the detection device 3 may include: a rotation speed detection means 31 and a position detection means 32. Wherein, the rotation speed detecting device 31 is connected to the rotating device 1, and then the rotation speed detecting device 31 rotates along with the rotating device 1, so that the rotation speed detecting device 31 can detect the rotation information of the pipeline 9 to be welded.
The position detection device 32 is connected to the position adjustment device 4, and then the position detection device 32 moves along with the position adjustment device 4, so that the position adjustment device 4 not only drives the welding gun 5 to move in the moving process, so that the welding gun 5 is matched with the position of the spiral weld, but also drives the position detection device 32 to move, so that the position detection device 32 can detect the position information of the spiral weld of the pipeline 9 to be welded in real time. In specific implementation, an insulating structure is provided between the position detection device 32 and the welding gun 5.
The control device 2 is connected with the rotating speed detection device 31 and the position detection device 32, and the control device 2 is used for receiving the rotating information sent by the rotating speed detection device 31 and the position information sent by the position detection device 32, calculating the rotating speed and the rotating angle of the pipeline 9 to be welded according to the rotating information, calculating the distance required to be moved by the welding gun 5 according to the position information, and controlling the position adjusting device 4 to move so that the travelling speed and the position of the welding gun 5 are matched with the rotating speed and the position of the spiral welding seam. Specifically, the control device 2 controls the position adjusting device 4 to move so that the traveling speed of the welding torch 5 matches the rotational speed of the spiral weld, that is, the traveling speed of the welding torch 5 matches the rotational speed of the pipe 9 to be welded, based on the calculated rotational speed and rotational angle. The control device 2 controls the position adjusting device 4 to move according to the calculated distance that the welding gun 5 needs to move so that the position of the welding gun 5 matches the position of the spiral weld.
In specific implementation, the rotation speed detecting device 31 may be determined according to actual conditions, as long as the rotation information of the pipe 9 to be welded can be detected, which is not limited in this embodiment. The position detection device 32 may also be determined according to actual conditions, as long as it can detect the position information of the spiral weld, and this embodiment does not limit this. Preferably, the rotation speed detecting device 31 is an encoder; and/or, the position detection device 32 is a laser vision sensor. The encoder is used to record rotation data of the pipe 9 to be welded, and the control device 2 calculates the rotation speed and the rotation angle from the rotation data. The laser vision sensor is used for scanning the position information of the spiral welding seam, and the control device 2 calculates the distance that the welding gun 5 needs to move according to the position information. In specific implementation, when the rotation speed detecting device 31 is an encoder and the position detecting device 32 is a laser vision sensor, the encoder and the laser vision sensor are respectively connected with the control device 2 through cables.
It can be seen that, in this embodiment, the control device 2 adjusts the traveling speed of the welding gun 5 according to the detected rotation information, so that the traveling speed of the welding gun 5 can be kept consistent with the rotation speed of the pipeline 9 to be welded, the consistency of the welding gun 5 and the spiral weld in the traveling direction is effectively ensured, a basic condition is provided for ensuring the position matching of the welding gun 5 and the spiral weld, and the control device 2 adjusts the position of the welding gun 5 according to the detected position information, so that the position of the welding gun 5 can be always kept consistent with the position of the spiral weld, the welding gun 5 is ensured to be welded to an accurate position, and the welding quality is further ensured.
Referring to fig. 1 to 6, in each of the above embodiments, the position adjustment device 4 may include: a support mechanism 41, an X-axis adjustment mechanism 42, a Y-axis adjustment mechanism 43, and a Z-axis adjustment mechanism 44. The X-axis adjusting mechanism 42 is connected to the supporting mechanism 41, because the pipe 9 to be welded is fixed and rotated under the action of the rotating device 1, the pipe 9 to be welded has a certain distance from the ground or the working platform, and the position adjusting device 4 needs to be placed above the pipe 9 to be welded (as compared with fig. 1) to enable the welding gun 5 to weld the spiral weld, so the X-axis adjusting mechanism 42 is connected to the supporting mechanism 41. In specific implementation, the specific structure of the supporting mechanism 41 may be determined according to actual situations, as long as the supporting mechanism 41 plays a supporting role and does not limit the movement of the X-axis adjusting mechanism 42, which is not limited in this embodiment.
The X-axis adjusting mechanism 42 is connected to the Z-axis adjusting mechanism 44 via the Y-axis adjusting mechanism 43, and the welding gun 5 is connected to the Z-axis adjusting mechanism 44. Specifically, the X-axis adjusting mechanism 42, the Y-axis adjusting mechanism 43, and the Z-axis adjusting mechanism 44 form a three-dimensional coordinate system, the X-axis adjusting mechanism 42 indicates the X-axis direction, the Y-axis adjusting mechanism 43 indicates the Y-axis direction, and the Z-axis adjusting mechanism 44 indicates the Z-axis direction, so that the movement of the position adjusting device 4, i.e., the movement of the X-axis adjusting mechanism 42, the Y-axis adjusting mechanism 43, and the Z-axis adjusting mechanism 44 in the three-dimensional coordinate system, corresponds the movement of the position adjusting device 4 to a certain coordinate point in space, and further drives the welding gun 5 to move to a certain coordinate point, where the coordinate point matches the position of the spiral weld.
The control device 2 is connected to the X-axis adjustment mechanism 42, and the control device 2 adjusts the travel speed of the X-axis adjustment mechanism 42 in the X-axis direction based on the calculated rotation speed and rotation angle to adjust the travel speed of the welding gun 5. Specifically, the pipeline 9 to be welded is driven by the rotating device 1 to rotate in situ, and the direction of the X axis is consistent with the advancing direction of the spiral weld. Since the welding torch 5 is connected to the Z-axis adjustment mechanism 44 and the Z-axis adjustment mechanism 44 is connected to the X-axis adjustment mechanism 42 via the Y-axis adjustment mechanism 43, adjustment of the travel speed of the X-axis adjustment mechanism 42 in the X-axis direction can be effected on adjustment of the travel speed of the welding torch 5.
In the above process, the adjustment of the traveling speed of the X-axis adjusting mechanism 42 is used to bring the movements of the Y-axis adjusting mechanism 43 and the Z-axis adjusting mechanism 44 together. Specifically, although the control device 2 controls and adjusts the travel speed of the X-axis adjustment mechanism 42 in the X-axis direction, the travel speed of the welding torch 5 is reflected in the forward movement of the welding torch 5 with respect to the welding torch 5, and therefore the travel speed of the X-axis adjustment mechanism 42 in the X-axis direction is finally converted into the movement of the welding torch 5. The adjustment of the traveling speed of the X-axis adjusting mechanism 42 in the X-axis direction can be converted into a movement in the X-axis direction, which drives the movement of the Y-axis adjusting mechanism 43 in the X-axis direction and also drives the movement of the Z-axis adjusting mechanism 44 in the X-axis direction, thereby realizing the movement of the welding gun 5 in the X-axis direction, so that the traveling speed of the welding gun 5 matches the rotation speed of the pipe 9 to be welded.
The control device 2 is connected to both the Y-axis adjusting mechanism 43 and the Z-axis adjusting mechanism 44, and the control device 2 is further configured to control the moving distance of the Y-axis adjusting mechanism 43 in the Y-axis direction and the moving distance of the Z-axis adjusting mechanism 44 in the Z-axis direction according to the calculated distance that the welding gun 5 needs to move, so as to adjust the position of the welding gun 5. Wherein the movement of the Y-axis adjustment mechanism 43 is used to drive the movement of the Z-axis adjustment mechanism 44. Specifically, the X-axis adjustment mechanism 42 adjusts the movement in the X-axis direction, ensuring the traveling speed of the welding gun 5. The Y-axis adjustment mechanism 43 and the Z-axis adjustment mechanism 44 adjust the position of the welding gun 5 so that the position of the welding gun 5 and the position of the spiral weld remain matched. When the control device 2 calculates the distance to be moved by the welding torch 5 also from the coordinate points in the three-dimensional coordinate system, the control device 2 can calculate the movement distance of the welding torch 5 in the Y-axis direction and the movement distance in the Z-axis direction. The Y-axis adjusting mechanism 43 moves to a distance required to move in the Y-axis direction under the action of the control device 2, and simultaneously drives the Z-axis to move by the same distance in the Y-axis direction, thereby driving the welding gun 5 to move by the same distance in the Y-axis direction. The Z-axis adjusting mechanism 44 is moved by the control device 2 to a distance required to move in the Z-axis direction, and drives the welding gun 5 to move by the same distance in the Z-axis direction. At this time, the welding torch 5 is moved in the three-dimensional coordinate system in conjunction with the movement in the X-axis direction, the Y-axis direction, and the Z-axis direction, so that the final position of the welding torch 5 matches the position of the spiral weld.
It can be seen that, in this embodiment, the position adjusting device 4 forms a three-dimensional coordinate system through the X-axis adjusting mechanism 42, the Y-axis adjusting mechanism 43, and the Z-axis adjusting mechanism 44, and adjusts the position of the welding gun 5 in the three-dimensional coordinate system, that is, the position of the welding gun 5 is adjusted in an actual space, so as to better meet actual conditions, and not only can be matched with the rotation speed of the pipeline 9 to be welded, but also can be matched with the position of the spiral weld, thereby ensuring the accuracy of the welding position and improving the welding quality.
Referring to fig. 1 to 5, in the above embodiment, at least one of the X-axis adjusting mechanism 42, the Y-axis adjusting mechanism 43, and the Z-axis adjusting mechanism 44 includes: a driving motor 6, a lead screw 7, a slide block 8 and a guide rail. That is, when the X-axis adjusting mechanism 42 includes: the specific structures of the Y-axis adjusting mechanism 43 and the Z-axis adjusting mechanism 44 are not limited at all when the motor 6, the lead screw 7, the slider 8, and the guide rail are driven. Accordingly, when the Y-axis adjusting mechanism 43 includes: the specific structure of the X-axis adjusting mechanism 42 and the Z-axis adjusting mechanism 44 is not limited at all when the motor 6, the lead screw 7, the slider 8, and the guide rail are driven. Accordingly, when the Z-axis adjusting mechanism 44 includes: the specific structure of the X-axis adjusting mechanism 42 and the Y-axis adjusting mechanism 43 is not limited at all when the motor 6, the lead screw 7, the slider 8, and the guide rail are driven. No matter which structure form the X-axis adjusting mechanism 42, the Y-axis adjusting mechanism 43, and the Z-axis adjusting mechanism 44 belong to, it is sufficient if the movement of the Y-axis adjusting mechanism 43 and the Z-axis adjusting mechanism 44 can be driven while the adjustment of the traveling speed of the X-axis adjusting mechanism 42 can be ensured, and the movement of the Y-axis adjusting mechanism 43 can be driven while the movement of the Z-axis adjusting mechanism 44 is driven.
The drive shaft of driving motor 6 is connected with lead screw 7, and slider 8 is movably connected in lead screw 7, and driving motor 6 is used for driving lead screw 7 to rotate, and then drives slider 8 and remove along lead screw 7. Specifically, a driving motor 6 is connected to the control device 2, and the driving motor 6 is used for driving a lead screw 7 to rotate under the control of the control device 2. The slider 8 is sleeved outside the screw rod 7, and the slider 8 is in threaded connection with the screw rod 7, so that the rotation of the screw rod 7 is converted into the movement of the slider 8.
Although the slider 8 moves along the lead screw 7, the motion track of the slider 8 can be ensured to be a straight line, in actual operation, the slider 8 can shake in the moving process, and the welding gun 5 directly shakes in the moving process, so that welding deviation is caused, and welding quality is influenced. In order to avoid the shaking of the sliding block 8, a guide rail is provided, the sliding block 8 is movably connected with the guide rail, and the guide rail is used for limiting the moving track of the sliding block 8. The guide rail can set up in one side of lead screw 7, and guide rail and lead screw 7 parallel arrangement, slider 8 slide along the guide rail for the guide rail has restricted rocking of slider 8, has ensured that slider 8 keeps rectilinear movement, avoids appearing rocking. In specific implementation, the form of the guide rail may be determined according to actual conditions, and the embodiment does not limit this. Preferably, the guide rail is a dovetail groove guide rail.
Preferably, there are two guide rails, the two guide rails are respectively disposed on two sides of the screw rod 7, and two ends of the sliding block 8 are respectively movably connected with the two guide rails in a one-to-one correspondence manner. Specifically, two guide rails are disposed on the left and right sides of the lead screw 7, respectively. One end of the slider 8 is movably connected to one of the guide rails, and the other end of the slider 8 is movably connected to the other guide rail. Like this, can restrict slider 8 between two guide rails effectively, guaranteed that slider 8 is rectilinear movement along lead screw 7, avoid rocking of slider 8, and then guaranteed welder 5's stable welding, ensure welding quality.
More preferably, both guide rails are dovetail guide rails. In specific implementation, the slider 8 includes: the first connecting plate, the second connecting plate and the third connecting plate are connected in sequence, the first connecting plate and the third connecting plate are arranged in parallel and are both perpendicular to the second connecting plate, and then the sliding block 8 can be in a shape like the Chinese character 'ji'. First connecting plate and third connecting plate are movably connected with two guide rails one-to-one, are provided with the threaded sleeve between lead screw 7 and the second connecting plate, and lead screw 7 is located to the threaded sleeve cover to, threaded sleeve's inner wall and lead screw 7 threaded connection, threaded sleeve's outer wall is connected with the second connecting plate. The rotation of lead screw 7 drives the removal of threaded sleeve, and then drives the removal of second connecting plate, and then drives first connecting plate and third connecting plate and remove along two guide rails ground.
It can be seen that, in the present embodiment, the X-axis adjusting mechanism 42, the Y-axis adjusting mechanism 43, and the Z-axis adjusting mechanism 44 are simple in structure and easy to implement.
Referring to fig. 1 to 5, in the above embodiment, when the X-axis adjusting mechanism 42, the Y-axis adjusting mechanism 43, and the Z-axis adjusting mechanism 44 each include: when the motor 6, the lead screw 7, the slider 8 and the guide rail are driven, the connection structures among the drive motor 6, the lead screw 7, the slider 8 and the guide rail in the X-axis adjusting mechanism 42, the Y-axis adjusting mechanism 43 and the Z-axis adjusting mechanism 44 are all the same, and specific connection relations can be referred to the above description. In order to realize the connection between the Y-axis adjusting mechanism 43 and the X-axis adjusting mechanism 42 and realize the movement of the X-axis adjusting mechanism 42 to drive the Y-axis adjusting mechanism 43, the driving motor 6 and the lead screw 7 in the Y-axis adjusting mechanism 43 are both connected with the slider 8 in the X-axis adjusting mechanism 42. That is, the driving motor 6 and the lead screw 7 in the Y-axis adjusting mechanism 43 are fixed to the slider 8 in the X-axis adjusting mechanism 42, so that the movement of the slider 8 of the X-axis adjusting mechanism 42 brings the overall movement of the Y-axis adjusting mechanism 43 and does not affect the movement of the slider 8 in the Y-axis adjusting mechanism 43.
In specific implementation, the driving motor 6 and the lead screw 7 in the Y-axis adjusting mechanism 43 can be wrapped by a shell, and the slider 8 in the X-axis adjusting mechanism 42 is connected with the shell by a connecting plate, so that the driving motor 6 and the lead screw 7 in the Y-axis adjusting mechanism 43 are both connected with the slider 8 in the X-axis adjusting mechanism 42.
Regarding the connection between the Z-axis adjusting mechanism 44 and the Y-axis adjusting mechanism 43, there are two embodiments, one of which is: the driving motor 6 and the lead screw 7 of the Z-axis adjusting mechanism 44 are connected to the slider 8 of the Y-axis adjusting mechanism 43, that is, the driving motor 6 and the lead screw 7 of the Z-axis adjusting mechanism 44 are fixed on the slider 8 of the Y-axis adjusting mechanism 43, so that the movement of the slider 8 of the Y-axis adjusting mechanism 43 drives the overall movement of the Z-axis adjusting mechanism 44, and does not affect the movement of the slider 8 of the Z-axis adjusting mechanism 44. The welding torch 5 is connected to the slider 8 in the Z-axis adjusting mechanism 44.

The operation of the pipe helical weld welding device will be described in detail with reference to fig. 1 to 7. The rotation speed detecting device 31 is an encoder, and the position detecting device 32 is a laser vision sensor. The X-axis adjusting mechanism 42, the Y-axis adjusting mechanism 43, and the Z-axis adjusting mechanism 44 each include: a driving motor 6, a lead screw 7, a slide block 8 and a guide rail.
And starting the rotary positioner 11 to rotate the pipeline 9 to be welded. It takes a while for the pipe 9 to be welded to move from the initial movement to the uniform movement, and the rotation speed of the pipe 9 to be welded is constantly changing in this process, and therefore, it is necessary to match the traveling speed of the welding gun 5 with the rotation speed of the pipe 9 to be welded. An encoder on the rotary positioner 11 records the rotation data of the pipeline 9 to be welded and sends the rotation data to the control device 2 in the form of pulse light waves. The control device 2 receives the pulse light wave, analyzes the pulse light wave, calculates the rotation speed and the rotation angle of the pipeline 9 to be welded, and controls and adjusts the rotation speed of the driving motor 6 of the X-axis adjusting mechanism 42 according to the rotation speed and the rotation angle so that the rotation speed of the driving motor 6 of the X-axis adjusting mechanism 42 matches the rotation speed of the pipeline 9 to be welded. In the process of adjusting the rotation speed of the driving motor 6 of the X-axis adjusting mechanism 42, the rotation of the driving motor 6 drives the lead screw 7 to rotate, and further drives the sliding block 8 to move along the lead screw 7, that is, the sliding block 8 moves along the X-axis direction. In addition, the movement of the slide block 8 of the X-axis adjusting mechanism 42 drives the movement of the Y-axis adjusting mechanism 43, and further drives the movement of the Z-axis adjusting mechanism 44, so that the movement of the welding gun 5 in the X-axis direction is realized, and the moving speed of the welding gun 5 in the X-axis direction is matched with the rotating speed of the pipeline 9 to be welded.
After the pipeline 9 to be welded moves at a constant speed, the driving motor 6 of the X-axis adjusting mechanism 42 keeps rotating at a constant speed, so that the sliding block 8 of the X-axis adjusting mechanism 42 keeps moving at a constant speed, and further the welding gun 5 is driven to move at a constant speed. The laser vision sensor detects the position information of the spiral weld and sends the position information to the control device 2. The control device 2 receives the position information, analyzes and processes the position information, calculates a distance that the welding gun 5 needs to move in the Y-axis direction and a distance that the welding gun needs to move in the Z-axis direction, controls the driving motor 6 of the Y-axis adjusting mechanism 43 to rotate according to the distance that the welding gun needs to move in the Y-axis direction, and controls the driving motor 6 of the Z-axis adjusting mechanism 44 to rotate according to the distance that the welding gun needs to move in the Z-axis direction. The driving motor 6 of the Y-axis adjusting mechanism 43 rotates to drive the lead screw 7 to rotate, and further drives the slider 8 to move in the Y-axis direction to a required distance and then stop, in this process, the movement of the slider 8 of the Y-axis adjusting mechanism 43 drives the driving motor 6 of the Z-axis adjusting mechanism 44 and the lead screw 7 to move in the Y-axis direction, and further the welding gun 5 is moved in the Y-axis direction. The driving motor 6 of the Z-axis adjusting mechanism 44 rotates under the action of the control device 2 to drive the lead screw 7 to rotate, and further drives the slider 8 to move in the Z-axis direction to a required distance and then stop, in this process, the slider 8 of the Z-axis adjusting mechanism 44 moves to drive the welding gun 5 to move in the Z-axis direction. The position of the welding gun 5 after the movement of the X-axis adjusting mechanism 42, the Y-axis adjusting mechanism 43 and the Z-axis adjusting mechanism 44 can be matched with the position of the spiral weld, thereby realizing the welding of the spiral weld by the welding gun 5.
It should be noted that, in the process from the initial movement to the uniform movement of the pipe 9 to be welded, the welding gun 5 not only needs to adjust the traveling speed, i.e., the movement in the X-axis direction, but also needs to weld the spiral weld, and therefore, in this process, the control device 2 also calculates the distance that the welding gun 5 needs to move according to the position information detected by the laser vision sensor, and controls the movement of the Y-axis adjusting mechanism 43 and the Z-axis adjusting mechanism 44 so that the position of the welding gun 5 matches the position of the spiral weld.
In conclusion, the position of the welding gun 5 can be matched with the position of the spiral welding line of the pipeline to be welded 9 all the time, the deviation in the welding process can be corrected in real time, the welding quality is guaranteed, the welding yield and the welding efficiency are improved, and the labor intensity of workers is reduced.
