[0025] like Figure 1 to Figure 7As shown, it shows a suspended long-arm electric welder for pipe fittings in one embodiment of the present disclosure, including a processing table 1, including a clamping device, a welding mechanism 2 is arranged on the top of the processing table 1, a hydraulic cylinder 3 is fixedly installed on the top of the processing table 1, a clamping slide 4 is slidably installed on the top of the processing table 1, a clamping table 5 is fixedly installed on the top of the processing table 1, and the clamping device includes a hydraulic cylinder 2 61, a clamping plate 62, a support plate 63, a spiral rod 64, a centering plate 65, an extrusion rod 66, a clamping block 67 and an inclined plate 68, the hydraulic cylinder 2 61 is fixedly installed on the top of the clamping table 5, the clamping plate 62 is fixedly installed It is fixedly installed at the output end of the hydraulic cylinder 61, the support plate 63 is fixedly installed at the bottom of the clamping platform 5, the screw rod 64 rotates and penetrates the inner wall of the clamping platform 5, the center plate 65 is slidably installed on the circumferential surface of the screw rod 64, the extrusion rod 66 is fixedly installed on the surface of the clamping plate 62, the clamping block 67 is slidably installed on the surface of the support plate 63, and the inclined plate 68 is fixedly installed on the surface of the clamping block 67. The extrusion rod 66 moves to contact and squeeze the inclined plate 68 to move in the direction close to the metal pipe. Under the action of the extrusion rod 66, the inclined plate 68 moves and drives the clamping block 67 to move until the two ends of the metal pipe are clamped.

[0026] In some examples, a telescopic elastic rod 69 is fixedly installed on the surface of the support plate 63, and the free end of the telescopic elastic rod 69 is fixedly connected to the clamping block 67. The spiral rod 64 rotates and penetrates the surface of the clamping plate 62. The surface of the extrusion rod 66 is set as inclined surface 1, and the surface of the inclined plate 68 is set as inclined surface 2. The material of the centering plate 65 is a flexible material. The spiral rod 64 and the centering plate 65 are connected by threads. At the same time, the rotation of the spiral rod 64 drives the centering plate 65 to move downward. At this time, the downward movement of the centering plate 65 has the effect of centering and positioning the pipeline.

[0027] The screw rod 64 is connected to the center plate 65 by a threaded connection, the clamping plate 62 is connected to the screw rod 64 by a threaded connection, the surface of the clamping platform 5 is provided with arc surface 1, the surface of the clamping plate 62 is provided with arc surface 2, the surface of the support plate 63 is provided with arc surface 3, the clamping plate 62 and the screw rod 64 are connected by a threaded connection, and when the clamping plate 62 moves under the action of the hydraulic cylinder 2 61, it drives the screw rod 64 to rotate.

[0028] For example, Figure 1 to Figure 7As shown, when the present embodiment is working: the staff places the two sections of metal pipes to be processed on the surfaces of the clamping slide 4 and the clamping table 5 respectively, and starts the hydraulic cylinder 2 61. The output end of the hydraulic cylinder 2 61 moves downward to drive the clamping plate 62 to move until the pipe is clamped. At the same time, the clamping plate 62 moves downward to drive the extrusion rod 66 to move. At the same time, the extrusion rod 66 moves to contact and squeeze the inclined plate 68 to move in the direction close to the metal pipe. The inclined plate 68 moves under the action of the extrusion rod 66 to drive the clamping block 67 to move until the two ends of the metal pipe are clamped, thereby avoiding the influence of loose clamping on the stability during welding work, thereby reducing the welding accuracy or causing improper welding. The screw rod 64 is connected by a thread. When the clamping plate 62 moves under the action of the hydraulic cylinder 61, it drives the screw rod 64 to rotate. Since the screw rod 64 is connected to the centering plate 65 by a thread, the rotation of the screw rod 64 drives the centering plate 65 to move downward. At this time, the centering plate 65 moves downward to center and position the pipeline, and can flexibly clamp the metal pipeline to avoid slight shaking or vibration during welding, which may lead to inaccurate welding results. Then, when the clamping work of the metal pipeline is ready, the hydraulic cylinder 3 is started, and the output end of the hydraulic cylinder 3 moves to drive the clamping slide 4 to move toward the clamping platform 5 until the metal pipelines at both ends contact each other. Then the welding mechanism 2 is started, and the welding mechanism 2 welds the metal pipelines at both ends.

[0029] like Figure 1 to Figure 7 As shown, it shows that another embodiment of the present disclosure includes a guiding device and a cleaning device, the guiding device includes a toothed plate 71, a rotating shaft 72, a gear 73, an eccentric wheel 74, a U-shaped plate 75, a knocking rod 76, a U-shaped rod 77, a telescopic column 78 and a guide plate 79, the toothed plate 71 is fixedly mounted on the surface of the clamping slide 4, the rotating shaft 72 is rotatably mounted on the surface of the clamping table 5, the gear 73 is fixedly mounted on the end of the rotating shaft 72 away from the hydraulic cylinder 2 61, the eccentric wheel 74 is fixedly mounted on the end of the rotating shaft 72 away from the gear 73, the U-shaped plate 75 is slidably mounted on the surface of the clamping table 5, the knocking rod 76 is fixedly mounted on the surface of the U-shaped plate 75, the U-shaped rod 77 is fixedly mounted on the surface of the clamping slide 4, the telescopic column 78 is fixedly mounted on the surface of the processing table 1, and the guide plate 79 is fixedly mounted on the top of the free end of the telescopic column 78, the U-shaped rod 77 moves to contact and squeeze the U-shaped slide groove opened on the free end surface of the telescopic column 78 to move upward, and the free end of the telescopic column 78 moves upward to drive the guide plate 79 to move upward. In some examples, a U-shaped groove is provided on the surface of the free end of the telescopic column 78, and the tooth plate 71 is engaged with the gear 73. The tooth plate 71 is engaged with the gear 73, and at the same time, the tooth plate 71 moves to contact and drive the gear 73 to rotate, and the rotation of the gear 73 drives the rotating shaft 72 to rotate.

[0030] The surface of the guide plate 79 is set to be an arc surface 4, and the shape of the U-shaped rod 77 is set to be U-shaped. The U-shaped rod 77 moves to contact and squeeze the U-shaped sliding groove opened on the free end surface of the telescopic column 78 to move upward.

[0031] The cleaning device includes a fixed rod 81, a turntable 82, a reciprocating screw rod 83, a turntable 84, a connecting plate 85, an air box 86, a sliding rod 87, a pressure plate 88, a baffle 89, an air jet tube 810, a slide rail 811 and a brush plate 812. The fixed rod 81 is fixedly mounted on the end of the rotating shaft 72 away from the gear 73, the turntable 82 is fixedly mounted on the end of the fixed rod 81 away from the eccentric wheel 74, the reciprocating screw rod 83 is rotatably mounted on the surface of the clamping table 5, the turntable 84 is fixedly mounted on the end of the reciprocating screw rod 83 away from the clamping table 5, and the connecting plate 85 is slidably mounted on the reciprocating screw rod 83. The circumferential surface of the rod 83, the air box 86 is fixedly installed on the top of the processing table 1, the sliding rod 87 is fixedly passed through the surface of the connecting plate 85, the pressure plate 88 is slidably installed on the inner wall of the air box 86, the baffle 89 is fixedly installed on the surface of the pressure plate 88, the air injection pipe 810 is fixedly passed through the surface of the air box 86, the slide rail 811 is fixedly installed on the top of the processing table 1, and the brush plate 812 is slidably installed on the inner wall of the slide rail 811. At the same time, the pressure plate 88 moves upward under the action of the sliding rod 87 to drive the brush plate 812 to move, and the brush plate 812 moves to achieve the effect of brushing and cleaning the welding surface.

[0032] A telescopic elastic rod 2 813 is fixedly installed on the top of the processing table 1, and the telescopic elastic rod 2 813 is fixedly connected to the bottom of the brush plate 812. The connecting plate 85 is connected to the reciprocating screw rod 83 by a threaded connection. The surface of the brush plate 812 is provided with bristles. The pressure plate 88 is fixedly connected to the brush plate 812, and the sliding rod 87 is fixedly connected to the pressure plate 88. The turntable 1 82 is in contact with the turntable 2 84. The rotation of the fixed rod 81 drives the turntable 1 82 to rotate, which drives the turntable 2 84 to rotate. The rotation of the turntable 2 84 drives the reciprocating screw rod 83 to rotate.

[0033] For example, Figure 1 to Figure 7As shown, when this embodiment is working: when the clamping slide 4 moves under the action of hydraulic cylinder 3, it drives the tooth plate 71 to move in the direction close to the clamping platform 5. Because the tooth plate 71 is meshed with the gear 73, the tooth plate 71 moves, contacts and drives the gear 73 to rotate. The rotation of the gear 73 drives the rotating shaft 72 to rotate. The rotation of the rotating shaft 72 drives the eccentric wheel 74 to rotate. At the same time, the eccentric wheel 74 rotates, contacts and squeezes the U-shaped plate 75 to move in the direction close to the metal pipe. At this time, the U-shaped plate 75 moves and drives the knocking rod 76 to move to knock the metal pipe, so that the clamp and the metal pipe are in closer contact and the metal pipe docking work is better. At the same time, the dust or impurities attached to the surface of the metal pipe can be knocked and shaken off. At the same time, when the clamping slide 4 moves in the direction close to the clamping platform 5, it will drive the U-shaped rod 77 to move. The U-shaped rod 77 moves, contacts and squeezes the free space of the telescopic column 78. The U-shaped slot on the end surface moves upward, and the free end of the telescopic column 78 moves upward, driving the guide plate 79 to move upward, thereby supporting the bottom of the metal pipe and guiding the metal pipe clamped by the clamping slide 4 to better dock with the metal pipe at the other end, avoiding inaccurate welding surface fitting due to inaccurate docking, thereby affecting the final welding effect. At this time, the U-shaped rod 77 continues to move under the action of the clamping slide 4 until it moves to the end of the U-shaped slot close to the clamping table 5. At this time, when the free end of the telescopic column 78 loses the effect of the U-shaped rod 77 on it, the telescopic column 78 deforms and recovers, driving the guide plate 79 to move downward, thereby realizing the adaptive guiding effect of the metal pipe, guiding during docking and resetting during welding, thereby avoiding the guide plate 79 from maintaining contact with the metal pipe during welding and affecting the welding work.

[0034] When the rotating shaft 72 rotates under the action of the gear 73, the rotating shaft 72 rotates and drives the fixed rod 81 to rotate. At the same time, the fixed rod 81 rotates and drives the turntable 1 82 to rotate and drives the turntable 2 84 to rotate. The turntable 2 84 rotates and drives the reciprocating screw rod 83 to rotate. Because the reciprocating screw rod 83 and the connecting plate 85 are connected by threads, the reciprocating screw rod 83 rotates and drives the connecting plate 85 to move downward. At the same time, the connecting plate 85 moves and drives the pressure plate 88 to move downward. The pressure plate 88 moves downward to spray the gas inside the air box 86 to the welding area through the jet pipe 810, and the welding port is jetted to clean the dust attached to the surface before welding, so that it is more stable in the subsequent welding process. The welding port after welding is completed will be jetted to blow off the welding slag attached to the welding surface to prevent the welding slag from affecting the final appearance of the metal pipe. At the same time, the pressure plate 88 moves upward under the action of the sliding rod 87 to drive the brush plate 812 to move. The brush plate 812 moves to achieve the effect of brushing and cleaning the welding surface, further improving the appearance of the metal pipe after welding.
