[0038] Example 2: According to Figure 1-Figure 7As shown, the device body 1 includes a workbench 101, a laser ranging sensor 117 and an industrial camera 118. A controller 102 and a robotic arm 103 are installed on the upper side of the workbench 101. A welding gun 104 is provided on the robotic arm 103. Two perforated seats 105 and two mounting seats 106 are installed on the top of the workbench 101. A shell 107 is rotatably sleeved inside each perforated seat 105, and an auxiliary rod 108 is rotatably sleeved inside each mounting seat 106. Two mounting brackets 109 are installed on the lower side of the workbench 101, a servo motor 110 is installed on one side of one of the mounting brackets 109, and a round rod 111 is rotatably sleeved between the insides of the two mounting brackets 109. The outer surface of each auxiliary rod 108 is fixedly sleeved with a first sprocket 112, and the outer surface of the round rod 111 is fixedly sleeved with two second sprockets 113. Two rectangular holes 114 are provided on the top, and two mounting holes 115 are provided on the inner wall of each shell 107. The four mounting holes 115 are divided into two groups. A rectangular plate 116 is installed between the inside of each group of mounting holes 115. The controller 102 is electrically connected to the laser ranging sensor 117, and the controller 102 is electrically connected to the industrial camera 118. Each first sprocket 112 is connected to each second sprocket 113 through a chain transmission, and each chain is rotatably sleeved on the inside of each rectangular hole 114. The controller 102 is electrically connected to the robotic arm 103, the controller 102 is electrically connected to the welding gun 104, and the controller 102 is electrically connected to the servo motor 110. The opposite end faces of the two auxiliary rods 108 are respectively fixed to the opposite sides of the two shells 107, and the output end of the servo motor 110 is installed with one end of the round rod 111.

[0039] In this embodiment, when the device body 1 is needed to position and weld a steel structure workpiece, the controller 102 is first connected to the external power supply, and then the welding gun 104 is connected to the corresponding external device. Then, the two rectangular plates 116 are removed from the inside of the corresponding set of mounting holes 115, and then the two steel structure workpieces to be welded are placed inside the two shells 107 respectively, and the welding positions are contacted, and then the two rectangular plates 116 are reset to their original positions (as shown in FIG. Figure 1As shown), the controller 102 is then used to start the laser distance sensor 117, the industrial camera 118 and the servo motor 110. At this time, the started servo motor 110 will drive the round rod 111 to rotate under the cooperation of the two mounting brackets 109 and the workbench 101. The rotating round rod 111 will drive the two first sprockets 112 to rotate under the cooperation of the two chains, the two second sprockets 113 and the two rectangular holes 114. At the same time, the two rotating first sprockets 112 will rotate on the corresponding auxiliary rods 108. , the corresponding mounting seat 106 and the corresponding hole seat 105 cooperate to drive the corresponding shell 107 to rotate, and the two rotating shells 107 will drive the corresponding steel structure workpiece to rotate under the cooperation of the corresponding set of mounting holes 115 and the corresponding rectangular plate 116. At the same time, the activated laser ranging sensor 117 and the activated industrial camera 118 will detect the welds of the steel structure workpiece under the cooperation of the two rotating steel structure workpieces, and the detected weld data will be recorded in the form of electricity. The signal is transmitted to the controller 102, and the controller 102 calculates and processes the received weld data. When the two steel structure workpieces are rotated 360 degrees and the weld detection is completed, the controller 102 directly turns off the servo motor 110, the laser ranging sensor 117 and the industrial camera 118. The turned-off servo motor 110 will stop the rotation of the two steel structure workpieces with the cooperation of the above-mentioned components. Then the controller 102 will start the robot arm 103 and the welding gun 104 according to the processed weld data. The started robot arm 103 will perform welding operations on the two steel structure workpieces with the cooperation of the started welding gun 104 and the workbench 101. When the welding operation of the two steel structure workpieces is completed, the controller 102 will directly turn off the robot arm 103 and the welding gun 104, and then remove the two rectangular plates 116 from the inside of the corresponding set of mounting holes 115. Then, the two steel structure workpieces that have completed the welding operation are removed from the inside of the two shells 107, and then follow the above-mentioned operating steps.

[0040] The effect and working principle of the entire mechanism are as follows:

[0041] During the use phase, when the device body 1 is needed to position and weld a steel structure workpiece, the controller 102 is first connected to the external power supply, and then the welding gun 104 is connected to the corresponding external device. Then, the two rectangular plates 116 are removed from the inside of the corresponding set of mounting holes 115, and then the two steel structure workpieces to be welded are placed inside the two shells 107 respectively, and the welding positions are contacted, and then the two rectangular plates 116 are reset to their original positions (as shown in FIG. Figure 1As shown), the controller 102 is then used to start the laser distance sensor 117, the industrial camera 118 and the servo motor 110. At this time, the started servo motor 110 will drive the round rod 111 to rotate under the cooperation of the two mounting brackets 109 and the workbench 101. The rotating round rod 111 will drive the two first sprockets 112 to rotate under the cooperation of the two chains, the two second sprockets 113 and the two rectangular holes 114. At the same time, the two rotating first sprockets 112 will rotate on the corresponding auxiliary rods 108. , the corresponding mounting seat 106 and the corresponding hole seat 105 cooperate to drive the corresponding shell 107 to rotate, and the two rotating shells 107 will drive the corresponding steel structure workpiece to rotate under the cooperation of the corresponding set of mounting holes 115 and the corresponding rectangular plate 116. At the same time, the activated laser ranging sensor 117 and the activated industrial camera 118 will detect the welds of the steel structure workpiece under the cooperation of the two rotating steel structure workpieces, and the detected weld data will be recorded in the form of electricity. The signal is transmitted to the controller 102, and the controller 102 calculates and processes the received weld data. When the two steel structure workpieces are rotated 360 degrees and the weld detection is completed, the controller 102 directly turns off the servo motor 110, the laser ranging sensor 117 and the industrial camera 118. The turned-off servo motor 110 will stop the rotation of the two steel structure workpieces under the cooperation of the above-mentioned components. Then the controller 102 will start the robot arm 103 and the welding gun 104 according to the processed weld data. The started robot arm 103 will perform welding operations on the two steel structure workpieces under the cooperation of the started welding gun 104 and the workbench 101. When the welding operation of the two steel structure workpieces is completed, the controller 102 will directly turn off the robot arm 103 and the welding gun 104, and then remove the two rectangular plates 116 from the inside of the corresponding set of mounting holes 115. Then, remove the two steel structure workpieces that have completed the welding operation from the inside of the two shells 107, and then operate according to the above-mentioned operating steps.

[0042] During the protection phase, when the laser ranging sensor 117 and the industrial camera 118 need to be protected from splashing, the controller 102 is first used to start the drive motor 202. The started drive motor 202 will drive the first rotating rod 204 to rotate under the cooperation of the auxiliary frame 201 and the corresponding set of cylindrical holes 213. The rotating first rotating rod 204 will drive the double-hole plate 205 to rotate inside the auxiliary hole 203. At the same time, the rotating double-hole plate 205 will drive the corresponding auxiliary plate 210, the laser ranging sensor 117 and the industrial camera 118 to rotate, and the rotating double-hole plate 205 will drive the protective plate 209 to rotate with the cooperation of the two mounting grooves 206, the two fixed pulleys 207, the two steel wire ropes 212, the corresponding set of cylindrical holes 213 and the second rotating rod 208. At the same time, the rotating protective plate 209 will drive the counterweight block 211 and the corresponding auxiliary plate 210 to rotate. When the double-hole plate 205 rotates 90 degrees, the surface of the other auxiliary plate 210 just contacts the surface of the auxiliary frame 201. At the same time, the controller 102 will directly turn off the drive motor 202. At this time, the turned-off drive motor 202 will cause all the above components to stop rotating (such as Figure 4 As shown), when welding the steel structure workpiece, the laser ranging sensor 117 and the industrial camera 118 can be protected from splashing with the cooperation of the protective plate 209 and the auxiliary frame 201. When the laser ranging sensor 117 and the industrial camera 118 need to be used, the drive motor 202 is directly started by the controller 102. At this time, the started drive motor 202 can, with the cooperation of the above-mentioned components, make the laser ranging sensor 117 and the industrial camera 118 reset and rotate. When the laser ranging sensor 117 and the industrial camera 118 are reset to their original positions, the drive motor 202 can be directly turned off by the controller 102.

[0043] Among them, the controller 102, robotic arm 103, welding gun 104, servo motor 110, laser ranging sensor 117, industrial camera 118 and drive motor 202 are all existing technologies, and their working principles are all public technologies. Their models can be selected according to actual conditions and will not be explained in detail here.
