Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a welding equipment for a pipe connector and a use method thereof. Background Art

[0002] Pipe connectors are components used to connect pipes in a pipeline system to other pipes or pipelines. When existing reducer pipe connectors are connected to other pipes, welding equipment is generally used to weld the two pipes together to ensure that there is no gap at the connection and to ensure the normal operation of the pipeline system in the future.

[0003] In the existing technology, the existing pipe connector welding equipment can stably weld the reducer pipe connector and other pipes together and ensure that there is no gap in the joint after welding during actual use, but it does not have a detection function. When the reducer pipe connector is welded with other pipes, cracks may appear at the joint due to welding process and welding environment. However, traditional detection methods mostly use direct observation with the naked eye. When a large number of such welded pipe connections need to be inspected, the workload of the staff will be greatly increased, the processing efficiency will be reduced, and the use effect of the pipe connector welding equipment will be reduced.

[0016] A method for using a welding device for a pipe connector comprises the following steps:

[0017] S1. When it is necessary to weld the reducing pipe connector with other pipes, the pipe to be welded is first squeezed and fixed on the other end of the reducing pipe connector placed on one of the multi-slot blocks by using the cooperation of the controller, electric push rod, concave column, U-shaped frame, connecting rod, two multi-slot blocks, rotating rod, housing, driving motor and bearing, and then the position and angle of the laser head of the laser welding gun are adjusted by using the cooperation of the adjustment frame, and then the reducing pipe connector in close contact and the pipe in contact with it are driven to rotate together by using the cooperation of the controller, driving motor, housing, rotating rod, two multi-slot blocks, U-shaped frame, mounting frame, processing table, connecting frame, electric push rod, concave column, bearing and connecting rod;

[0018] S2. When the reducing pipe connector and the pipe in contact with it rotate together, the laser welding body, the laser transmission optical fiber and the laser welding gun are used to perform laser welding on the connection between the rotating reducing pipe connector and the pipe in contact with it. When the welding operation is completed, the controller, the motor body, the placement box, the rotating shaft, the gear, the limit hole, the limit block, the installation groove and the rack are used to move the grooved L-shaped block and the components installed on the grooved L-shaped block out of the placement box.

[0019] S3. When the L-shaped block with grooves moves to a suitable position, the air in the space formed by the placing box and the box cover is first filtered and then sucked in by the cooperation of the controller, the fan and the filter screen. Then, the air around the connecting head of the reducing pipe and the connecting part of the pipe in contact with it is driven to flow rapidly by the cooperation of the hose and the vent pipe. That is, the temperature of the above-mentioned connecting part is uniformly and quickly lowered by the cooperation of the flowing air. Finally, the controller, the camera, the image data stored in advance in the storage module of the controller and the cooperation of the two indicator lights are used to determine whether the detected component is qualified.

[0020] S4. After the detection operation of the reducing pipe connector and the connection of the pipe in contact with it is completed, the controller, the motor body and the previous linkage components are used to make the slotted L-shaped block and the components installed on the slotted L-shaped block return to their original positions. At the same time, the controller, the electric push rod and the previous linkage components are used to make the corresponding multi-slot block return to its original position, and the welded components can be removed to carry out the next component welding operation.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention provides an auxiliary mechanism, so that when inspecting the connection of a large number of components obtained by welding a reducing pipe connector with other pipes, it is not necessary for the staff to inspect with the naked eye, thereby reducing the workload of the staff and improving the processing efficiency. It not only improves the use effect of the welding equipment of the pipe connector, but also improves the use efficiency of the welding equipment of the pipe connector. When the laser welding operation is completed at the connection between the reducing pipe connector and the pipe in contact with it, the controller, the motor body, the placement box and the rotating shaft are first used to rotate the gear, and then the rotating gear, the placement box, the limit hole, the limit block, the installation groove and the rack are used to move the grooved L-shaped block and the components installed on the grooved L-shaped block out of the placement box.

[0023] 2. When the L-shaped block with grooves of the present invention moves to a suitable position, the motor body can be paused by using the cooperation of the controller. Then, the air in the space composed of the placing box and the box cover can be filtered and then sucked in by using the cooperation of the controller, the fan and the filter screen. Then, the air around the connection of the reducing pipe connector and the pipe in contact with it can be driven to flow quickly, that is, the temperature of the above connection can be evenly and quickly lowered by using the cooperation of the flowing air, saving time and avoiding the waste of time of self-heating cooling. After that, the controller, the camera, the picture data stored in advance in the storage module of the controller and the two indicator lights can be used to determine whether the detected component is qualified. When the connection of the reducing pipe connector and the pipe in contact with it completes the detection operation, the L-shaped block with grooves and the components installed on the L-shaped block with grooves can be reset to their original positions by using the cooperation of the controller, the motor body and the previous linkage components.

[0024] 3. The present invention can laser weld and fix the reducing pipe connector with other pipe fittings by setting a welding mechanism. When the reducing pipe connector needs to be welded with other pipe fittings, the pipe fitting to be welded therewith can be squeezed and fixed on the other end of the reducing pipe connector placed on one of the multi-slot blocks by first using the cooperation of the controller, the electric push rod, the concave column, the U-shaped frame, the connecting rod, the two multi-slot blocks, the rotating rod, the shell, the driving motor and the bearing. Then, the position and angle of the laser head of the laser welding gun can be adjusted by using the cooperation of the adjusting frame. Then, the reducing pipe connector in close contact and the pipe fitting in contact therewith can be driven to rotate together by using the cooperation of the controller, the driving motor, the shell, the rotating rod, the two multi-slot blocks, the U-shaped frame, the mounting frame, the processing table, the connecting frame, the electric push rod, the concave column, the bearing and the connecting rod.

[0025] 4. In the present invention, when the reducer connector and the pipe in contact with it rotate together, the laser welding body, the laser transmission optical fiber and the laser welding gun can be directly used to cooperate to realize the laser welding operation on the connection between the rotating reducer connector and the pipe in contact with it. When the welding operation of the two is completed, the laser welding body can be used to stop the laser welding gun from performing the laser welding operation on the connection between the two. Then, the adjustment frame can be used to drive the laser head of the laser welding gun to move its position and fix it after moving it to the appropriate position.

[0026] 5. In the present invention, after the detection operation of the reducing pipe connector and the connection of the pipe in contact therewith is completed, the corresponding multi-slot block can be reset to its original position by utilizing the cooperation of the controller, the electric push rod and the previous linkage components. When the corresponding multi-slot block is reset to its original position, the welded components can be removed and the next component welding operation can be carried out.

[0040] In this embodiment, when the laser welding operation is completed, the controller 109 is directly used to start the motor body 206. At this time, the started motor body 206 will drive the gear 205 to rotate with the cooperation of the placement box 201 and the rotating shaft 204, and the rotating gear 205 will drive the slotted L-shaped block 207 and the components installed on the slotted L-shaped block 207 to move out of the placement box 201 with the cooperation of the placement box 201, the limiting hole 214, the limiting block 209, the installation groove 216 and the rack 217.

[0041] Embodiment 2: According to Figure 1-Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the welding mechanism 1 includes a processing table 101, a mounting frame 102 is installed on the top of the processing table 101, a connecting frame 103 is installed on the front surface of the mounting frame 102 near the top position, a U-shaped frame 104 is installed on the front surface of the connecting frame 103, an electric push rod 105 is installed on the top of the U-shaped frame 104, the bottom end of the telescopic end of the electric push rod 105 movably passes through the top of the U-shaped frame 104, a concave column 106 is fixed to the bottom end of the telescopic end of the electric push rod 105, and a connecting rod 107 is rotatably connected to the inside of the concave column 106 through a bearing, a shell 108 is installed on the top of the processing table 101, a controller 109 is installed on the outer wall of the shell 108, a drive motor 110 is installed on the inner wall of the shell 108, and a rotating rod 111 is installed on the output end of the drive motor 110. The bottom end of the rotating rod 111 movably passes through the top of the shell 108, and the top of the rotating rod 111 and the bottom of the connecting rod 107 are both installed with multi-slot blocks 112, and the centers of the two multi-slot blocks 112 are on the same vertical line. A connecting plate 113 is fixed inside the processing table 101, and an adjusting frame 114 is installed on the side of the mounting frame 102 away from the placement box 201. A laser welding gun 115 is installed on the mounting end of the adjusting frame 114, and a laser welding body 117 is installed on the top of the connecting plate 113. A cylindrical hole 116 is opened on the top of the inner wall of the processing table 101, and the interior of the cylindrical hole 116 is connected to the interior of the mounting frame 102. The laser welding gun 115 is connected to the laser welding body 117 through a laser transmission optical fiber, and the drive motor 110 and the controller 109 are electrically connected.

[0042] In this embodiment, when it is necessary to weld the reducing pipe connector to other pipes, one end of one of the reducing pipe connectors is first placed in the groove of the corresponding diameter on one of the multi-groove blocks 112, and then the pipe to be welded is placed on the other end of the reducing pipe connector, and the position is adjusted. Then, the electric push rod 105 is started by the controller 109. At this time, the telescopic end of the started electric push rod 105 will drive the other multi-groove block 112 to move under the cooperation of the concave column 106, the U-shaped frame 104 and the connecting rod 107. When the top of the pipe in contact with the reducing pipe connector is in contact with the multi-groove block 112, When the pipe fittings in contact with the reducing pipe connector are butted against the grooves of the corresponding diameters, the electric push rod 105 is kept started. When the pipe fittings in contact with the reducing pipe connector are tightly squeezed and fixed on the reducing pipe connector, the controller 109 will pause the electric push rod 105, and then use the adjustment frame 114 to move the laser head of the laser welding gun 115 to the connection between the reducing pipe connector and the pipe fittings in contact therewith, and fix the laser head of the laser welding gun 115 after it has completed the movement, and then use the controller 109 to start the drive motor 110. At this time, the started drive motor 110 will rotate between the housing 108, the rotating rod 111, and the two The multi-slot block 112, the U-shaped frame 104, the mounting frame 102, the processing table 101, the connecting frame 103, the electric push rod 105, the concave column 106, the bearing and the connecting rod 107 cooperate to drive the closely contacted reducing pipe connector and the pipe in contact with it to rotate together. When the reducing pipe connector and the pipe in contact with it rotate together, the laser welding main body 117, the laser transmission optical fiber and the laser welding gun 115 are directly used to perform laser welding operation on the connection between the rotating reducing pipe connector and the pipe in contact with it. When the welding operation of the two is completed, the laser welding is directly closed. The main body 117 stops the laser welding gun 115 from performing the laser welding operation on the connection between the two, and then uses the adjustment frame 114 to remove the laser head of the laser welding gun 115, and fixes it after moving it to a suitable position. After the detection operation is completed at the connection between the reducer and the pipe in contact with it, the corresponding multi-slot block 112 is reset to its original position by using the cooperation of the controller 109, the electric push rod 105 and the previous linkage components, and then the welded components (composed of the welding of the reducer and the pipe in contact with it) can be removed to perform the next component welding operation.

[0043] The effect and working principle achieved by the entire mechanism are as follows: when it is necessary to weld the reducer connector to other pipe fittings, first connect the controller 109 to the external power supply through the prepared power cord, then connect the laser welding body 117 to the external power supply using the power cord connected thereto, then turn on the controller 109, and store the image data of the cracks (images of cracks appearing at the connection between the reducer connector and other pipe fittings after they are welded together) in the storage module in the controller 109, then turn on the laser welding body 117, set the use parameters and use procedures, and at the same time set that when there is no crack at the connection between the reducer connector and the pipe fitting in contact therewith and the detection is qualified, one of the indicators is turned on. The indicator light 203 is lit, and similarly, the other indicator light 203 is lit (the colors of light emitted when the two indicator lights 203 are lit are different). When everything is ready, first place one end of one of the reducer pipe connectors on the groove of the corresponding caliber on one of the multi-slot blocks 112, then place the pipe welded to it on the other end of the reducer pipe connector, and adjust the position, then use the controller 109 to start the electric push rod 105. At this time, the telescopic end of the started electric push rod 105 will drive the other multi-slot block 112 to move with the cooperation of the concave column 106, the U-shaped frame 104 and the connecting rod 107. When the top of the pipe in contact with the reducer pipe connector is docked with the groove of the corresponding caliber on the multi-slot block 112, continue to maintain The electric push rod 105 is started. When the pipe in contact with the reducing pipe connector is tightly squeezed and fixed on the reducing pipe connector, the controller 109 will pause the electric push rod 105. Then, the adjustment frame 114 is used to move the laser head of the laser welding gun 115 to the connection between the reducing pipe connector and the pipe in contact with it, and the laser head of the laser welding gun 115 is fixed after the movement is completed. Then, the controller 109 is used to start the drive motor 110. At this time, the started drive motor 110 will cooperate with the housing 108, the rotating rod 111, the two multi-slot blocks 112, the U-shaped frame 104, the mounting frame 102, the processing table 101, the connecting frame 103, the electric push rod 105, the concave column 106, the bearing and the connecting rod 107. Under the condition that the reducing pipe connector in close contact with the pipe in contact with it rotates together, when the reducing pipe connector and the pipe in contact with it rotate together, the laser welding main body 117, the laser transmission optical fiber and the laser welding gun 115 are directly used to perform laser welding operation on the connection between the rotating reducing pipe connector and the pipe in contact with it. When the welding operation of the two is completed, the laser welding main body 117 is directly closed, and the laser welding gun 115 is stopped to perform laser welding operation on the connection between the two. Then, the laser head of the laser welding gun 115 is removed by using the adjustment frame 114, and it is fixed after being moved to a suitable position. When the laser welding operation of the connection between the reducing pipe connector and the pipe in contact with it is completed,At this time, the controller 109 is directly used to start the motor body 206. At this time, the started motor body 206 will drive the gear 205 to rotate under the cooperation of the placement box 201 and the rotating shaft 204. The rotating gear 205 will drive the slotted L-shaped block 207 and the components installed on the slotted L-shaped block 207 to move out of the placement box 201 under the cooperation of the placement box 201, the limiting hole 214, the limiting block 209, the installation groove 216 and the rack 217. When the slotted L-shaped block 207 moves to a suitable position, the controller 109 will pause the motor body 206. At this time, the air outlet of the ventilation pipe 211 is just aligned with the connection between the reducing pipe connector and the pipe in contact therewith, and the connection is also just in the shooting position of the camera 210. range, and then the controller 109 will start the fan 213. Then the started fan 213 will, with the cooperation of the filter screen plate 215 connected thereto, filter and then inhale the air in the space formed by the placement box 201 and the box cover 202. Then the clean gas inhaled into the fan 213 will be transported to the inside of the hose 212, and then transported to the inside of the ventilation pipe 211, and then ejected from the outlet of the ventilation pipe 211 to the connection between the above two. At this time, the air around the connection between the above two will flow rapidly, that is, the flowing air will take away the heat of the rotating reducer connector and the connection of the pipe in contact with it, so that the temperature of the connection can be evenly and quickly reduced, saving energy. About time, to avoid wasting time for self-heating cooling. When the temperature of the connection reaches room temperature, the controller 109 is directly used to turn off the fan 213, and then the camera 210 is started. The started camera 210 will take pictures of the rotating reducer connector and the connection of the pipe in contact with it, and convert them into electrical signals, and transmit them to the controller 109. When the controller 109 receives these image data, the controller 109 will compare each image data with the image data stored in its storage module in advance. When each image data received by the controller 109 is different from the image data stored in its storage module in advance by the controller 109, it means that there is no crack at the connection between the above two. If the product is a qualified product, the controller 109 will light up the corresponding qualified indicator light 203 for the staff to observe and understand. Similarly, when one of the image data received by the controller 109 is the same as the image data previously stored in the storage module of the controller 109, it means that there is a crack at the connection between the two, which means the product is a unqualified product. The controller 109 will light up the corresponding unqualified indicator light 203 for the staff to observe and understand. When the detection operation of the reducing pipe connector and the connection of the pipe in contact with it is completed, the controller 109 will directly turn off the camera 210, and through the cooperation of the motor body 206 and the previous linkage components, the slotted L-shaped block 207 and the components installed on the slotted L-shaped block 207 are reset to their original positions.When the slotted L-shaped block 207 and the components mounted on the slotted L-shaped block 207 are reset to their original positions, the controller 109 will turn off the motor body 206, and then use the electric push rod 105 and the previous linkage components to reset the corresponding multi-slot block 112 to its original position, so that the welded components (composed of the different-diameter pipe connector and the pipes in contact therewith) can be removed, and the next component welding operation can be carried out, that is, when inspecting a large number of such welded two pipe connections, it is not necessary for the staff to inspect them with the naked eye, thereby reducing the workload of the staff and improving the processing efficiency, which not only improves the use effect of the pipe connector welding equipment, but also improves the use efficiency of the pipe connector welding equipment.
