[0001] The invention relates to the technical field of welding devices, in particular to an automatic butt welding device with a detection function. Background Art

[0002] Welding is a common metal processing method used to manufacture and repair various structures and equipment. A welding device is a device used to connect two or more workpieces together by melting. A butt welding device is used to butt the ends of two or more workpieces. Butt welding is usually done with workpieces such as round pipes to ensure the quality and strength of the welded joint. Existing butt welding devices still have some shortcomings.

[0003] The pipe welding docking device disclosed in publication number CN105965199B includes two docking machine frames, an angle pipe support, two spiral push rods and two spinnable blocks. The docking machine frame is in the shape of a handle, having a horizontal upper end, a vertical middle part and a lower end at an angle of 135 degrees to the vertical middle part. The angle pipe support is made of a V-shaped metal material with two planes at 90 degrees, and the angle pipe support is fixed to the inner side inclined surface of the lower end of the two docking machine frames; a threaded through hole is opened on the horizontal upper end of the docking machine frame, and the central axis of the threaded through hole is perpendicular to the ridge line of the angle pipe support and is in the same plane as the ridge line of the angle pipe support; the spiral push rod is a rod with threads, and the lower part of the spiral push rod near the end is radially opened with a circular groove and accommodated in the spinnable block, and the lower end of the spiral push rod passes through the threaded through hole on the docking machine frame and can be screwed in or out through the threaded through hole.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the present invention is described in detail with reference to schematic diagrams.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example

[0025] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-Figure 10As shown, an automatic butt welding device with a detection function comprises a shell 1, a driving assembly 2 is installed on the shell 1, openings 3 are provided on both the left and right sides of the shell 1, a second transmission wheel 4 is installed in the shell 1, a first electric push rod 6 is installed on the second transmission wheel 4, a support block 7 is fixedly connected to the first electric push rod 6, a slide groove 8 is provided on the support block 7, a slide rod 9 is slidably installed in the slide groove 8, a first spring 10 is fixedly connected between the slide rod 9 and the support block 7, a welding tool 18 is fixedly installed on the top of the slide rod 9, the driving assembly 2 can drive the second transmission wheel 4 to rotate, and the second transmission wheel 4 can drive the first electric push rod 6, the slide rod 9 and the welding tool 18 to do circular motion when rotating to realize the surrounding welding function. In the process of surrounding welding, the vertical spacing between the slide rod 9, the support block 7 and the welding tool 18 to the central axis of the shell 1 is changed by extending or shortening the first electric push rod 6 to adapt to the welding work of round pipes with different outer diameters. The housing 1 is fixedly connected with a first connecting rod 13, the first connecting rod 13 is mounted with a second electric push rod 14, the second electric push rod 14 is connected with a guide ring 15, the guide ring 15 is provided with a groove 17, and a support assembly 16 is mounted between the guide ring 15 and the housing 1. Figure 1 It can be seen that the support assembly 16 and the first connecting rod 13 and the second electric push rod 14 are distributed on both sides of the guide ring 15. The support assembly 16 can support the left side of the guide ring 15 when the second electric push rod 14 is extended or shortened, ensuring that the guide ring 15 can move forward and backward smoothly. The guide ring 15 can drive the welding tool 18 to move back and forth through the undulating grooves 17 when the sliding rod 9 makes a circular motion, thereby improving the welding quality of the device. By changing the front and rear positions of the guide ring 15, the amplitude of the reciprocating movement of the welding tool 18 can be changed, thereby adapting to the welding work of two round pipes with different weld sizes. Connecting rings 21 are installed on the front and rear sides of the shell 1, and an outer ring 22 is rotatably installed on the connecting ring 21. A connecting plate 24 is fixedly connected to the outer ring 22. A detection assembly 25 is installed around the connecting ring 21, and an elastic rope 23 is installed between the outer ring 22 and the connecting ring 21. After the connecting ring 21 on the device is installed, the outer ring 22 can be pulled by the elastic rope 23, so that the connecting plate 24 acts on the detection component 25 around the connecting ring 21, so that the device can not only support the circular pipe to be welded, but also rotate the circular pipe to be welded while supporting the circular pipe, and use the detection component 25 to perform deformation detection on the circular pipe to be welded, so as to ensure the welding effect of the device.

[0027] In this embodiment, the structures of the outer shell 1 and the second transmission wheel 4 are both circular rings with fractures, and the front and rear sides of the second transmission wheel 4 are fixedly connected with convex rings 5. The outer walls of the second transmission wheel 4 and the convex ring 5 are in contact with the inner wall of the outer shell 1, ensuring that the second transmission wheel 4 can slide smoothly in the outer shell 1, so that the second transmission wheel 4 can subsequently realize the function of surrounding and welding the circular pipe.

[0028] In this embodiment, the driving assembly 2 includes a fixed block 201 welded to the outer shell 1, and a motor 202 is fixedly mounted on the fixed block 201. A first transmission wheel 203 is connected to the output shaft of the motor 202. The first transmission wheel 203 and the second transmission wheel 4 abut against each other. The first transmission wheel 203 is driven to rotate by the motor 202 on the fixed block 201, and the first transmission wheel 203 abuts against the second transmission wheel 4 and drives the second transmission wheel 4 to rotate. The first transmission wheels 203 symmetrically distributed on both sides of the outer shell 1 can adapt to the second transmission wheel 4 with an interrupted structure, ensuring that the second transmission wheel 4 can rotate continuously for welding.

[0029] In this embodiment, the second transmission wheel 4 is provided with a first friction pattern 11, and the first transmission wheel 203 is provided with a second friction pattern 12. The front and rear surfaces of the first transmission wheel 203 fit with the inner wall of the opening 3, and the position of the first transmission wheel 203 corresponds to the position of the opening 3. The first friction pattern 11 and the second friction pattern 12 can make the resistance of the contact surface between the first transmission wheel 203 and the second transmission wheel 4 large enough to ensure that the second transmission wheel 4 can rotate stably. The opening 3 can make the first transmission wheel 203 and the second transmission wheel 4 abut against each other.

[0030] In this embodiment, the slide bar 9 forms an elastic structure between the first spring 10 and the support block 7. The slide bar 9 is suitable for intermittently abutting against the inner wall of the groove 17 on the guide ring 15 when the second transmission wheel 4 rotates. The central axis of the slide bar 9 and the welding tool 18 is parallel to the central axis of the first electric push rod 6. Through the elastic structure on the device, the slide bar 9 intermittently passes through the inner walls of multiple grooves 17 when the second transmission wheel 4 rotates, so that the slide bar 9 can intermittently move in the axial direction of the second transmission wheel 4 under the action of the first spring 10, so as to enhance the firmness of the welding of the device later.

[0031] In this embodiment, the support assembly 16 includes a protruding rod 1601 fixedly connected to the guide ring 15, a fixed plate 1603 is fixedly connected to the protruding rod 1601, a guide cylinder 1602 is sleeved on the outer side of the protruding rod 1601, a second connecting rod 1604 is fixedly connected to the guide cylinder 1602, the second connecting rod 1604 and the outer shell 1 are fixedly connected, the guide cylinder 1602 ensures that the guide ring 15 and the protruding rod 1601 can move forward and backward along the axial direction of the guide ring 15 itself, so that the guide ring 15 can be stably supported.

[0032] In this embodiment, the grooves 17 are evenly distributed along the circumference of the guide ring 15, and the two sides of the inner wall of the grooves 17 are inclined. The central axes of the guide ring 15, the outer shell 1 and the second transmission wheel 4 are all collinear, and there is a gap between the guide ring 15 and the second transmission wheel 4. The multiple grooves 17 on the guide ring 15 make the surface of the guide ring 15 form a circular continuous undulation, so that it can be continuously undulated during subsequent welding, thereby ensuring the welding effect of the device, and can also change the initial position of the guide ring 15, thereby adapting to welds of different sizes and changing the reciprocating distance during welding.

[0033] In this embodiment, the detection component 25 includes a guide rod 2501 that passes through the interior of the connecting ring 21, and a second spring 2502 is installed between the guide rod 2501 and the connecting ring 21. The second spring 2502 can automatically reset after the guide rod 2501 stops pressing down. A ball 2503 is rotatably installed on the side of the guide rod 2501 close to the central axis of the connecting ring 21. A scale mark is set on the guide rod 2501. The scale mark on the device can display the pressed length after the guide rod 2501 is pressed down, which is convenient for subsequent detection of whether the shape of the round tube to be welded has changed.

[0034] In this embodiment, a rotating groove 19 is provided on both the front and rear sides of the shell 1, and a rotating ring 20 is fitted in the rotating groove 19. The rotating ring 20 and the connecting ring 21 are fixedly connected. The connecting ring 21 forms a rotating structure with the shell 1 through the rotating groove 19 and the rotating ring 20. The connecting ring 21 can rotate on the shell 1 through the rotating structure on the device, which makes it more convenient for the device to detect the deformation degree of the circular tube to be welded. The circular tube to be welded can be kept stationary, and the rotating connecting ring 21 can realize the detection function.

[0035] In this embodiment, a fixing rod 26 is installed on the outer shell 1, and the connecting ring 21 and the fixing rod 26 are slidably connected. The elastic rope 23 and the connecting plate 24 are evenly distributed along the circumference of the connecting ring 21 and the outer ring 22. The evenly arranged elastic rope 23 can pull the outer ring 22 outside the connecting ring 21 to rotate. When the outer ring 22 rotates, it can make the connecting plates 24 at various locations move in a circular motion, so as to subsequently press and fix round tubes of different sizes. When the fixing rod 26 is installed, the connecting ring 21 can slide on the fixing rod 26. By rotating the round tube to be welded and keeping the connecting ring 21 stationary, the device can perform deformation detection work on different positions of the round tube.

[0036] It should be noted that the present invention is an automatic butt welding device with a detection function. First, Figure 1 and Figure 7-Figure 10As shown, the installation method of the connecting ring 21 can be adjusted during use, so as to adjust the detection method of the circular tube to be welded later. The fixing rod 26 can be installed on the outer shell 1, and then the connecting ring 21 is slidably installed on the fixing rod 26, and then the two circular tubes to be welded are installed in the connecting rings 21 on the front and rear sides of the outer shell 1. The outer ring 22 is pulled to rotate on the connecting ring 21 by the elastic rope 23, and the guide rod 2501 is pressed against the connecting plate 24, so that the ball 2503 on the guide rod 2501 is pressed against the surface of the circular tube to achieve the clamping of the circular tube. While clamping the circular tube, the connecting ring 21 can be moved back and forth by keeping the circular tube still, and then the circular tube can be rotated to observe whether the scale mark on the guide rod 2501 changes significantly, so as to detect the deformation of the circular tube at different positions. Figure 8-Figure 10 As shown, the device can rotatably install the connecting ring 21 on the outer shell 1 through the rotating groove 19 and the rotating ring 20, and keep the round tube to be welded stationary by rotating the connecting ring 21 on the outer shell 1, and observe the scale change of the guide rod 2501, so as to perform deformation detection on a specific position of the round tube.

[0037] like Figure 1-Figure 7 As shown, the device can start welding after the detection is completed and it is determined that the round tube to be welded has not been deformed. During welding, the elastic rope 23 pulls the outer ring 22 to make the connecting plate 24 abut against the guide rod 2501. After the ball 2503 on the guide rod 2501 abuts against the round tube, the central axis of the round tube is aligned with the central axis of the shell 1, and the first transmission wheel 203 can be driven to rotate by the motor 202 on the fixed block 201. The second friction pattern 12 on the first transmission wheel 203 abuts against the first friction pattern 11 on the second transmission wheel 4, thereby driving the second transmission wheel 4 to rotate, and the second transmission wheel 4 By smoothly rotating the convex ring 5 in the housing 1 and rotating the first electric push rod 6 at the same time, when the first electric push rod 6, the support block 7, the slide bar 9 and the welding tool 18 make circular motion, the welding tool 18 can automatically weld the joints of the two round pipes to be welded, and in the welding process, the undulating structure formed by the multiple grooves 17 on the guide ring 15 can intermittently push the slide bar 9, so that the slide bar 9 can reciprocate in the slide groove 8 in the support block 7, and the first spring 10 enables the slide bar 9 and the welding tool 18 to automatically reset when the welding tool 18 moves backward, so as to ensure the welding firmness of the device. The device can also extend or shorten the second electric push rod 14 on the first connecting rod 13. The second electric push rod 14 will drive the guide ring 15 to move forward and backward. When the guide ring 15 moves forward and backward, the guide cylinder 1602 and the protruding rod 1601 that fit each other ensure that the left side of the guide ring 15 is stably supported. The guide ring 15 and the protruding rod 1601 can move forward and backward along the axial direction of the guide ring 15 itself, so that the guide ring 15 can be stably supported, and the abutment effect between the inner wall of the groove 17 on the guide ring 15 and the slide bar 9 changes. When the guide ring 15 is far back, the amplitude of the intermittent forward and backward movement of the slide bar 9 increases, so that the device can adapt to the welding of two round pipes with larger welds.

[0038] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
