Abstract

A scaffolding disc-lock upright workstation has a material feeding and pipe-threading device on one side of the main frame. A tooling platform is slidably installed on the main frame. Multiple flipping clamping devices are set on the tooling platform. A left clamping transmission device and a right clamping device are respectively fixed to the left and right ends of the front platform of the main frame. A top plate device is set at the bottom of the front of the main frame. The top plate device cooperates with the grabbing and feeding plate device to feed the workpiece disc into the flipping clamping device, clamp it, and flip it into place. The workpiece pipe is threaded into the workpiece disc by the material feeding and pipe-threading device. The tooling platform slides to push the workpiece into the welding position to complete spot welding and circumferential welding. After welding is completed, the two ends of the workpiece are released, and the welded workpiece slides down the unloading rack to the conveying device. The conveying device sends the welded workpiece into the material box, and the finished product is completed. It saves time and labor, has high production efficiency, low labor intensity, and can be completed without professional welders, which greatly reduces costs.

Description

Technical Field

[0001] This invention relates to an automatic welding machine, and more particularly to a scaffolding disc buckle upright workstation. Background Technology

[0002] Currently, the known technology for welding scaffolding uprights involves manually placing each coil one by one, followed by automated pipe threading. The latest technology also uses automated pipe threading and coil placement, but the automated coil placement and threading devices are unstable, causing the equipment to malfunction and resulting in low production efficiency. Summary of the Invention

[0003] To address the shortcomings of the aforementioned technical problems, the present invention aims to provide a scaffolding disc-lock pole erection workstation.

[0004] A scaffolding disc-lock upright workstation includes a main frame (3) and an air tank (20), welding power source (6), operation box (9), and power control box (2) installed on the main frame (3). Wire feeding disc shaft (5), wire feeding motor (4), and solenoid valve (26) are respectively fixed to the upper part of the main frame (3). The workstation is characterized by: a material feeding and pipe-threading device (1) on one side of the main frame (3); a tooling platform (28) slidably installed on the main frame (3); multiple flipping clamping devices (27) on the tooling platform (28); a left clamping transmission device (10) and a right clamping device (14) respectively fixed to the left and right ends of the front end platform of the main frame (3); and a top plate device (12) at the bottom front end of the main frame (3). The disc device (12) cooperates with the gripping and feeding disc device (8) installed on the main frame (3) to feed the workpiece disc (111) into the flipping clamping device (27) for clamping and flipping into place. The workpiece tube is inserted into the workpiece disc (111) through the feeding and tube-passing device (1). The tooling platform (28) slides to push the workpiece into the welding position. The left clamping transmission device (10) clamps and drives the workpiece tube to rotate. The right clamping device (14) assists the left clamping transmission device (10) in pressing the workpiece tube tightly to complete spot welding and circumferential welding. After welding is completed, the left clamping transmission device (10) and the right clamping device (14) release the workpiece, allowing the welded workpiece to slide down the unloading rack (24) onto the conveying device (25). The conveying device (25) sends the welded workpiece into the material frame.

[0005] The top plate device (12) includes a positioning column (109), a hopper bottom plate (110), a guide rail D (118), a slider D (119), a slider E (120), a guide rail E (121), a top plate cylinder connecting plate (122), a top plate cylinder (123), a top plate base (124), a top plate column (125), a pallet bottom plate (126), and a conversion cylinder (127). The top plate cylinder (123) is fixed to the front bottom of the main frame (3). One end of the cylinder connecting plate (122) is connected to the cylinder rod of the top plate cylinder (123), and the other end is connected to the top plate base (124). Two guide rails E (121) are vertically fixed on the internal vertical beam of the main frame (3). Slider E (120) is slidably installed on both guide rails E (121). The two ends of the top plate base (124) are connected and fixed to the slider E (120) by bolts. Multiple top plate columns (125) are evenly fixed on the upper surface of the top plate base (124).

[0006] Multiple guide rails D (118) are provided on the front platform of the main frame (3). A slider D (119) is slidably installed on each guide rail D (118). The pallet bottom plate (126) is fixed to the slider D (119) by bolts. A conversion cylinder (127) is installed on the front platform of the main frame (3). The cylinder rod of the conversion cylinder (127) is connected to one end of the pallet bottom plate (126). Multiple hopper bottom plates (110) are fixed to the pallet bottom plate (126) by bolts. Each hopper bottom plate (110) has two through holes, and two sets of positioning posts (109) are welded on each hopper bottom plate (110). The two positioning posts (109) form a set, and each set of positioning posts (109) corresponds to the through holes on the hopper bottom plate (110). Several workpiece discs (111) are mounted on each set of positioning posts (109). The workpiece discs (111) mounted on the positioning posts (109) are gripped by the gripping and feeding device (8).

[0007] The top plate device (12) further includes an upper limit controller (115), a controller bracket A (116), a lower limit controller (117), a disk signal controller (130), and a controller bracket B (131). The controller bracket A (116) is bolted to the right side of the bottom front end of the main frame (3). The upper limit controller (115) and the lower limit controller (117) are installed on the controller bracket A (116). The controller bracket B (131) is bolted to the right side of the front end platform of the main frame (3). The disk signal controller (130) is fixed to the upper end of the controller bracket B (131).

[0008] When the workpiece disc (111) placed on top of the positioning column (109) is picked up by the pallet gripping device (8), and the pallet signal controller (130) cannot detect the workpiece disc (111), the top plate cylinder (123) is activated, driving the top plate base (124) to move upward, so that the top plate column (125) installed on the top plate base (124) passes through the holes of the pallet bottom plate (126) and the hopper bottom plate (110), and at the same time lifts the workpiece disc (111). At this time, when the pallet signal controller (130) detects the workpiece disc (111), it controls the top plate cylinder (123) to activate the top plate cylinder (124). 23) Stop the operation. The workpiece disc (111) also stops moving so that the gripping and feeding device (8) can grab it. When the last workpiece disc (111) of the right group is grabbed, the upper limit controller (115) detects the signal and controls the top plate cylinder (123) to start falling. When the lower limit controller (117) detects the signal, the conversion cylinder (127) moves and pushes the pallet bottom plate (126) to move on the guide rail D (118) to push another group of workpiece discs (111) to the gripping position, completing the conversion so that the gripping and feeding device (8) can grab it.

[0009] The gripping and feeding device (8) includes a gripping beam (108), a pushing cylinder (112), a pushing slider (113), a pushing guide rail (114), a three-jaw cylinder (128), and a dropping cylinder (129). The pushing cylinder (112) and the pushing guide rail (114) are respectively installed on the two end columns of the main frame (3). A pushing slider (113) is slidably installed on each pushing guide rail (114). The two ends of the gripping beam (108) are bolted to the pushing slider (113). The cylinder rods of the two pushing cylinders (112) are connected to the gripping beam (108). Multiple dropping cylinders (129) are evenly installed on the gripping beam (108). Each dropping cylinder... Three-jaw cylinders (128) are installed on the cylinder rod of cylinder (129). When the cylinder rod of the lowering cylinder (129) extends, it drives the three-jaw cylinder (128) to move down, so that the cylinder claws of the three-jaw cylinder (128) fall into the hole in the middle of the workpiece disc (111). When the three-jaw cylinder (128) moves, it pushes the three cylinder claws of the three-jaw cylinder (128) outward to fix the workpiece disc (111). At this time, the cylinder rod of the lowering cylinder (129) retracts, driving the workpiece disc (111) to rise and get away from the positioning post (109). Through the action of the push plate cylinder (112), the workpiece disc (111) grabbed by the three-jaw cylinder (128) is sent to the corresponding flipping clamping device (27).

[0010] The workpiece disc (111) is gripped by the cylinder claw of the three-jaw cylinder (128) and placed on the tray plate (68) of the flipping clamping device (27). The flipping clamping device (27) clamps the workpiece disc (111) and flips it into place. The workpiece is then fed through the tube feeding and tube feeding device (1) for tube feeding. The tube feeding and tube feeding device (1) includes a feeding cylinder (30), a pulley (31), a tube rubbing cylinder (32), a guide rail B (33), a pressing connecting plate (34), and a tube rubbing support. The components include: frame (35), push tube guide rail (36), material support cylinder plate (37), material support guide post (38), material support cylinder connecting plate (39), material support cylinder (40), support frame (41), feeding frame (42), guide rail C (43), slider C (44), tube threading platform (45), push tube slider (46), push tube sliding plate (47), support mold (48), positioning tip (49), slider B (50), pressing cylinder (51), guide sleeve (141), and positioning cylinder (142).

[0011] Feeding cylinders (30) are installed at both ends of the upper part of the feeding frame (42). The feeding frame (42) is placed behind the pipe-passing platform (45). One side of the pipe-passing platform (45) is connected and fixed to the main frame (3) by bolts. A support pulley (41) is installed on the upper left side of the pipe-passing platform (45). Two guide rails C (43) are fixed on the main surface of the pipe-passing platform (45) by bolts. Sliding sliders C (44) are slidably installed on both guide rails C (43). The lower end of the tube-rubbing bracket (35) is fixed on the slider C (44). A pressing cylinder (51) and a slider B (50) are installed on the upper end of the tube-rubbing bracket (35). The guide rail B (33) is slidably installed on the slider B (50). The upper end of the guide rail B (33) is connected to the cylinder rod of the pressing cylinder (51) via the pressing connecting plate (34). A tube-rubbing cylinder (32) is installed on the lower end of the guide rail B (33). A pulley (31) is fixed on the shaft of the tube-rubbing cylinder (32).

[0012] The material support cylinder plate (37) is fixed to the main surface of the pipe-through platform (45) by bolts. The material support cylinder (40) and guide sleeve (141) are installed on the material support cylinder plate (37). The material support guide post (38) is inserted into the guide sleeve (141). The material support guide post (38) is connected to the cylinder rod of the material support cylinder (40) through the material support cylinder connecting plate (39).

[0013] Two push tube guide rails (36) are bolted to the upper end face of the tube-passing platform (45). Push tube sliders (46) are slidably installed on both push tube guide rails (36). Push tube sliding plate (47) is fixed on push tube slider (46). A support mold (48) is installed above the push tube sliding plate (47). The lower end of the push tube sliding plate (47) is connected to the cylinder rod of the tube-passing cylinder (13). The positioning cylinder (142) is fixed on the bottom surface of the support mold (48). A positioning tip (49) is installed on the cylinder rod of the positioning cylinder (142).

[0014] The loading frame (42) has a certain inclination. The workpiece tube is laid flat on the loading frame (42). The loading cylinder (30) is activated to feed the workpiece tube into the support mold (48) and the support guide column (38). The pressing cylinder (51) is activated to drive the guide rail B (33), thereby driving the tube rolling cylinder (32) and the pulley (31) to fall, so that the pulley (31) presses the tube. The tube rolling cylinder (32) and the positioning cylinder (142) are activated at the same time. The tube rolling cylinder (32) drives the pulley (31) to rotate, so that the pulley (31) rubs against the workpiece tube, thereby driving the workpiece tube to rotate. The positioning cylinder (142) The positioning tip (49) is inserted into the hole of the workpiece tube. Positioning is completed. The pressing cylinder (51) and the rubbing cylinder (32) are reset. The tube-passing cylinder (13) is activated, driving the support mold (48) to move the workpiece tube forward. After a certain time, the material-supporting cylinder (40) is activated, driving the material-supporting guide post (38) to retract, allowing the workpiece tube to continue moving forward. The tube-passing cylinder (13) moves to the position, allowing the workpiece tube to pass through the workpiece disc. Through the sliding of the tooling platform (28), the flipping clamping device (27) is moved, sending the workpiece tube and the workpiece disc (111) together into the welding position.

[0015] Three guide rails A (16) are bolted to the upper end of the front platform of the main frame (3). A slider A (17) is slidably installed on each guide rail A (16). The tooling platform (28) is fixed on the slider A (17). Multiple flip clamping devices (27) are evenly fixed on the upper surface of the tooling platform (28). The front push cylinder (23) is installed under the front platform of the main frame (3). One end of the front push connecting plate (22) is connected to the cylinder rod of the front push cylinder (23), and the other end is connected to the tooling platform (28). When the front push cylinder (23) moves, it drives the tooling platform (28) to move inward, thereby driving the flip clamping device (27) to push the workpiece disc (11) through. 1) The workpiece tube and workpiece disc (111) are fed into the welding position together. After the position controller (29) detects the signal, the tooling platform (28) stops moving. The left clamping transmission device (10) and the right clamping device (14) clamp the workpiece tube. The support device (15) supports the workpiece tube. The welding gun (21) is sent to the weld position through the gun feeding device (7). The welding power supply (6) is turned on and spot welding begins. After the spot welding is completed, the flipping clamping device (27) and the tooling platform (28) return to the initial position. The left clamping transmission device (10) clamps and drives the workpiece tube to rotate. While rotating, the welding power supply (6) is turned on again to complete one circumferential weld and weld the workpiece.

[0016] The welded workpiece slides down the unloading rack (24) onto the conveying device (25), and the conveying device (25) conveys the workpiece out. The conveying device (25) includes a transmission box (52), chain A (53), sprocket A (54), transmission motor plate (55), transmission motor (56), chain B (57), bearing (58), sprocket bushing (59), fixed shaft (60), sprocket B (61) and sprocket C (143).

[0017] Fixed shafts (60) are installed at both ends inside the transmission housing (52). Bearings (58) are installed at both ends of the left fixed shaft (60). A sprocket bushing (59) is fitted onto the bearing (58). A sprocket A (54) and a sprocket C (143) are welded onto the sprocket bushing (59). Bearings (58) are installed at both ends of the right fixed shaft (60). A sprocket bushing (59) is fitted onto the bearing (58). A sprocket A (54) is welded onto the sprocket bushing (59). Two chains A (53) are respectively hung on the sprockets A (54) at the left and right ends.

[0018] A transmission motor plate (55) is bolted to the transmission housing (52), and a transmission motor (56) is fixed on the transmission motor plate (55). A sprocket B (61) is inlaid on the shaft of the transmission motor (56), and the sprocket B (61) is connected to the sprocket C (143) through the chain B (57).

[0019] When the drive motor (56) is energized, it rotates and drives the sprocket C (143) to rotate through the chain B (57), thereby driving the sprocket A (54) to form a closed and continuous cyclic transmission structure through the chain A (53). The two chains A (53) continuously circulate and transmit, so that the workpieces welded on the chain A (53) are conveyed out through the cyclic transmission of the chain A (53).

[0020] The unloading rack (24) has a certain inclination and is fixed to the middle position of the lower end of the main frame (3) by bolts. One end of the unloading rack (24) is connected to the conveying device (25). The welded workpiece slides down the unloading rack (24) and falls into the chain A (53) of the conveying device (25), thereby conveying the workpiece out.

[0021] The beneficial effects of this invention are as follows: the workpiece disc placed on the top plate hopper device is picked up by the grabbing and feeding device and sent to the flipping clamping device for clamping and flipping. Then, the pipe is inserted, the tooling platform is pushed into the welding position, spot welding and circumferential welding are performed, the welding is completed, the two ends are loosened, and the workpiece is automatically unloaded onto the conveying device. The conveying device sends the welded workpiece into the material frame, and the finished product is completed. This method saves time and effort, has high production efficiency and low labor intensity, and can be completed without professional welders, which greatly reduces costs. Attached Figure Description

Each set of positioning posts 109 corresponds to the through holes on the hopper bottom plate 110. Several workpiece discs 111 are fitted on each set of positioning posts 109. The workpiece discs 111 fitted on the positioning posts 109 are gripped by the gripping and feeding device 8.

[0057] The top plate device 12 also includes an upper limit controller 115, a controller bracket A116, a lower limit controller 117, a disk signal controller 130, and a controller bracket B131. The controller bracket A116 is bolted to the right side of the bottom front end of the main frame 3. The upper limit controller 115 and the lower limit controller 117 are mounted on the controller bracket A116. The controller bracket B131 is bolted to the right side of the front end platform of the main frame 3. The disk signal controller 130 is fixed to the upper end of the controller bracket B131.

[0058] When the workpiece disc 111, placed on top of the positioning column 109, is grasped by the pallet-feeding device 8, and the pallet signal controller 130 fails to detect the workpiece disc 111, the top plate cylinder 123 actuates, causing the top plate base 124 to move upward. This allows the top plate column 125, mounted on the top plate base 124, to pass through the holes in the pallet bottom plate 126 and the hopper bottom plate 110, simultaneously lifting the workpiece disc 111. At this point, when the pallet signal controller 130 detects the workpiece disc 111, it controls the top plate cylinder 123 to stop. When the action stops, the workpiece disc 111 also stops moving so that the gripping and feeding device 8 can grab it. When the last workpiece disc 111 of the right group is grabbed, the upper limit controller 115 detects a signal and controls the top plate cylinder 123 to start falling. When the lower limit controller 117 detects a signal, the switching cylinder 127 is activated, pushing the pallet bottom plate 126 to move on the guide rail D118, pushing another group of workpiece discs 111 to the gripping position, completing the switching so that the gripping and feeding device 8 can grab it.

[0059] The gripping and feeding device 8 includes a gripping beam 108, a pushing cylinder 112, a pushing slider 113, a pushing guide rail 114, a three-jaw cylinder 128, and a dropping cylinder 129. The pushing cylinder 112 and the pushing guide rail 114 are respectively installed on the two end columns of the main frame 3. The pushing slider 113 is slidably installed on each pushing guide rail 114. The two ends of the gripping beam 108 are bolted to the pushing slider 113. The cylinder rods of the two pushing cylinders 112 are connected to the gripping beam 108. Multiple dropping cylinders 129 are evenly installed on the gripping beam 108. In each dropping cylinder 129... Each cylinder rod of cylinder 29 is equipped with a three-jaw cylinder 128. When the cylinder rod of the lowering cylinder 129 extends, it drives the three-jaw cylinder 128 to move downward, so that the cylinder claws of the three-jaw cylinder 128 fall into the hole in the middle of the workpiece disc 111. When the three-jaw cylinder 128 moves, it pushes the three cylinder claws outward to fix the workpiece disc 111. At this time, the cylinder rod of the lowering cylinder 129 retracts, driving the workpiece disc 111 to rise and disengage from the positioning post 109. Through the action of the push plate cylinder 112, the workpiece disc 111 grabbed by the three-jaw cylinder 128 is sent to the corresponding flipping clamping device 27.

[0060] like Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18As shown, the flipping clamping device 27 includes a clamping cylinder 62, a clamping cylinder plate 63, a guide rail E64, a slider E65, a clamping moving slide plate 66, a rotary cylinder 67, a pallet plate 68, a positioning pin 69, a straightening cylinder 70, a positioning bolt 71, a connecting rod 72, a pulley 73, a large column 74, a small column 145, a magnet 75, and a pin shaft 76. The clamping cylinder 62 is bolted to the clamping cylinder plate 63. The cylinder rod of the clamping cylinder 62 is connected to the clamping sliding plate 66. The clamping cylinder plate 63 is bolted to the tooling platform 28. Two guide rails E64 are bolted parallel to each other on the tooling platform 28. Slider E65s are slidably mounted on both guide rails E64. The clamping sliding plate 66 is mounted on the sliders E65. A rotary cylinder 67 is mounted on the rotary sliding plate 66. A pallet plate 68 is bolted to the shaft of the rotary cylinder 67. Two magnets 75 and two locating pins 69 are respectively inlaid on the large flat surface of the pallet plate 68. A 30° angled, 5mm wide arc bevel 77 is milled on both the top and bottom surfaces around the semi-circular arc of the pallet plate 68. The purpose is that even if the workpiece tube passing through the semi-circular arc surface 78 is not straight and has a slight bend, the workpiece tube will smoothly slide into the workpiece disc hole along the slope surface 77 on the semi-circular arc surface 78. The size of the semi-circular arc surface 78 is slightly smaller than the size of the center hole of the workpiece disk.

[0061] A straightening cylinder 70 is installed on the base plate of the clamping disc sliding plate 66. A large column 74 and a small column 145 are both welded to the base plate of the clamping disc sliding plate 66. A positioning bolt 71 passes through a hole in the small column 145 and engages with the cylinder rod of the straightening cylinder 70, pressing against the two lower surfaces of the connecting rod 72. A pulley 73 is fitted onto the upper shaft of the connecting rod 72. Rotating the positioning bolt 71 drives the connecting rod 72 to move left and right, thereby adjusting the position of the pulley 73. A pin 76 is embedded in the upper end of the large column 74. The pin 76 passes through the hole in the connecting rod 72, allowing the connecting rod 72 to swing left and right but not forward and backward. When the tube is inserted, the workpiece tube moves forward against the pulley 73. The straightening cylinder 70 extends and pushes against the lower end of the connecting rod 72 to prevent the pulley 73 from swinging left and right. The straightening workpiece tube can be quickly inserted into the workpiece disc (because the tube needs to pass through 6 workpiece discs 111 in succession, and the distance between the workpiece discs 111 is 500 mm).

[0062] like Figure 4 , Figure 5 , Figure 6As shown, the feeding and tube-threading device 1 includes a feeding cylinder 30, a pulley 31, a tube-rubbing cylinder 32, a guide rail B33, a pressing connecting plate 34, a tube-rubbing bracket 35, a tube-pushing guide rail 36, a material-supporting cylinder plate 37, a material-supporting guide post 38, a material-supporting cylinder connecting plate 39, a material-supporting cylinder 40, a support frame 41, a feeding frame 42, a guide rail C43, a slider C44, a tube-threading platform 45, a tube-pushing slider 46, a tube-pushing sliding plate 47, a support mold 48, a positioning tip 49, a slider B50, a pressing cylinder 51, a guide sleeve 141, and a positioning cylinder 142. The feeding frame 42 has a certain inclination. The workpiece round tube is laid flat on the feeding frame 42. Feeding cylinders 30 are installed at both ends of the upper part of the feeding frame 42. The feeding frame 42 is placed behind the tube-passing platform 45. One side of the tube-passing platform 45 is connected and fixed to the main frame 3 by bolts. A support bracket 41 is installed on the upper left side of the tube-passing platform 45. Two guide rails C43 are fixed on the main surface of the tube-passing platform 45 by bolts. Slider C44 is slidably installed on both guide rails C43. The lower end of the tube-rolling bracket 35 is fixed on the slider C44. A pressing cylinder 51 and a slider B50 are installed on the upper end of the tube-rolling bracket 35. The guide rail B33 is slidably installed on the slider B50. The upper end of the guide rail B33 is connected to the cylinder rod of the pressing cylinder 51 through the pressing connecting plate 34. A tube-rolling cylinder 32 is installed on the lower end of the guide rail B33. A pulley 31 is fixed on the shaft of the tube-rolling cylinder 32.

[0063] The material-supporting cylinder plate 37 is bolted to the main surface of the pipe-passing platform 45. A material-supporting cylinder 40 and a guide sleeve 141 are installed on the material-supporting cylinder plate 37. The material-supporting guide post 38 is inserted into the guide sleeve 141. The material-supporting guide post 38 is connected to the cylinder rod of the material-supporting cylinder 40 through the material-supporting cylinder connecting plate 39. Two push-tube guide rails 36 are bolted to the upper end face of the pipe-passing platform 45. Push-tube sliders 46 are slidably installed on both push-tube guide rails 36. The push-tube sliding plate 47 is fixed on the push-tube sliders 46. A support mold 48 is installed above the push-tube sliding plate 47. The lower end of the push-tube sliding plate 47 is connected to the cylinder rod of the pipe-passing cylinder 13. The positioning cylinder 142 is fixed to the bottom surface of the support mold 48. A positioning tip 49 is installed on the cylinder rod of the positioning cylinder 142.

[0064] The feeding cylinder 30 actuates, feeding the workpiece tube into the support mold 48 and the guide post 38. The pressing cylinder 51 actuates, driving the guide rail B33, which in turn drives the tube-rolling cylinder 32 and the pulley 31 to fall, causing the pulley 31 to press against the tube. Simultaneously, the tube-rolling cylinder 32 and the positioning cylinder 142 actuate, causing the pulley 31 to rotate, rubbing against the workpiece tube and thus rotating it. The positioning tip 49 on the positioning cylinder 142 inserts into the hole of the workpiece tube, completing the positioning. The pressing cylinder 51 and the tube-rolling cylinder 32 reset, and the tube-threading cylinder 13 actuates, driving the support mold 48 to... The workpiece tube moves forward. After a certain period of time, the material-supporting cylinder 40 actuates, causing the material-supporting guide column 38 to retract, allowing the workpiece tube to continue moving forward. The tube-penetrating cylinder 13 moves forward to its position, allowing the workpiece tube to penetrate into the workpiece disc. The tooling platform 28 slides, driving the flipping clamping device 27 to move, sending the workpiece tube and the workpiece disc 111 together into the welding position. After the forward-push-to-position controller 29 detects the signal, the tooling platform 28 stops moving. The left clamping transmission device 10 clamps and drives the workpiece tube to rotate. The right clamping device 14 cooperates with the left clamping transmission device 10 to press the workpiece tube tightly.

[0065] like Figure 22 , Figure 23 , Figure 24 As shown, the left clamping transmission device 10 includes a left clamping cylinder 88, a left clamping cylinder plate 89, a left slider 90, a left guide rail 91, a left center point 92, a main drive shaft 93, a main drive housing 94, a rotary motor 95, and a reducer 96. The left clamping cylinder plate 89 is bolted to the front platform of the main frame 12. The left clamping cylinder 88 is mounted on the left clamping cylinder plate 89. The cylinder rod of the left clamping cylinder 88 is connected to the main drive housing 94. Two left guide rails 91 are arranged parallel to each other on the front platform of the main frame 3. A left slider 90 is slidably mounted on the main drive housing 94, which is fixed on the left slider 90. A reducer 96 is mounted on the main drive housing 94. The motor shaft of the rotary motor 95 is connected to the input shaft of the reducer 96. One end of the main drive shaft 93 is connected to the output shaft of the reducer 61, and the other end of the main drive shaft 93 is equipped with a left center 92. When the left clamping cylinder 88 is activated, it drives the main drive housing 94 to move to the right. The left center 92 presses against the workpiece tube. The rotary motor 95 is energized and rotates, which drives the reducer 96 and thus drives the main drive shaft 93 to rotate, causing the workpiece tube to rotate.

[0066] like Figure 25 , Figure 26As shown, the right clamping device 14 includes a right guide rail 97, a right slider 98, a right clamping cylinder plate 99, a right clamping cylinder 100, a driven transmission housing 101, a driven transmission shaft 102, and a right center point 103. The right clamping cylinder plate 99 is bolted to the front platform of the main frame 3. The right clamping cylinder 100 is mounted on the right clamping cylinder plate 99. The cylinder rod of the right clamping cylinder 100 is connected to the driven transmission housing 101. The two right guide rails 97 are arranged parallel to each other on the front platform of the main frame 3. On the upper part, right sliders 98 are slidably installed on both right guide rails 97. The transmission housing 101 is fixed on the right sliders 98. One end of the transmission shaft 102 passes through the transmission housing 101 and is connected and fixed to the transmission housing 101. The other end of the transmission shaft 102 is equipped with a right tip 103. When the right clamping cylinder 100 is activated, it drives the transmission housing 101 to move to the left, so that the right tip 103 presses against the workpiece tube. After the workpiece tube is clamped, the support device 15 supports the workpiece tube.

[0067] like Figure 27 , Figure 28 , Figure 29 As shown, the support device 15 includes a bearing 104, a bearing support plate 105, a support cylinder plate 106, and a support cylinder 107. The support cylinder plate 106 is bolted to the front platform of the main frame 3. The support cylinder 107 is installed on the support cylinder plate 106. The cylinder rod of the support cylinder 107 is connected to the bearing support plate 105. The bearing 104 is installed on the bearing support plate 105. When the support cylinder 107 is activated, it drives the bearing support plate 105 to move, so that the bearing 104 supports the workpiece tube. The welding torch 21 is delivered to the weld position for welding through the torch feeding device 7.

[0068] like Figure 19 , Figure 20 , Figure 21 As shown, the gun feeding device 7 includes a welding gun clamp 79, a gun feeding sliding plate 80, a spring 81, a guide rail H82, a copper plate 83, long bolts 84, a gun feeding base plate 85, a gun feeding cylinder 86, and a slider H87. Two parallel guide rails H82 are provided on the gun feeding base plate 85, and sliders H87 are slidably mounted on both guide rails H82. The gun feeding sliding plate 80 is fixed to the sliders H87. At both ends of the gun feeding sliding plate 80, welding gun clamps 79 are provided for fixing the welding gun 21. The gun feeding cylinder 86 is bolted to the gun feeding base plate 85. The cylinder rod of the gun feeding cylinder 86 is connected to the gun feeding sliding plate 80. Two long bolts 84 pass through the gun feeding sliding plate 80 and are connected to the copper plate 83. Springs 81 are fitted on the long bolts 84. When the gun feeding cylinder 86 is activated, it drives the gun feeding sliding plate 80, thereby causing the welding gun 21 to slide on the guide rails H82. When the slide plate 80 moves downward, the copper plate 83 presses on the workpiece disc 111, and the welding torch 21 falls to the weld position to perform spot welding and circumferential welding.

[0069] like Figure 1 , Figure 2 As shown, one end of the welding torch 21 is connected to the wire feeding motor 4, and the other end is fixed on the welding torch clamp 79. The welding wire wound on the wire feeding disc shaft 5 is placed between the upper and lower wire feeding wheels of the wire feeding motor 4. The welding wire is clamped by the upper and lower wire feeding wheels and fed into the welding torch 21.

[0070] like Figure 3 , Figure 10 , Figure 11 , Figure 12 As shown, the welded workpiece slides down the unloading rack 24 onto the conveying device 25, which then conveys the workpiece out. The conveying device 25 includes a transmission housing 52, chain A53, sprocket A54, transmission motor plate 55, transmission motor 56, chain B57, bearing 58, sprocket bushing 59, fixed shaft 60, sprocket B61, and sprocket C143. Fixed shaft 60 is installed at both ends inside the transmission housing 52. Bearing 58 is installed at both ends of the left fixed shaft 60, and sprocket bushing 59 is fitted onto the bearing 58. Sprocket A54 and sprocket C143 are welded onto the sprocket bushing 59. Bearing 58 is installed at both ends of the right fixed shaft 60, and sprocket bushing 59 is fitted onto the bearing 58. Sprocket A54 is welded onto the sprocket bushing 59. Two chains A53 are respectively hung on the left and right sprockets A54. A drive motor plate 55 is bolted to the transmission housing 52. A drive motor 56 is fixed to the drive motor plate 55. A sprocket B61 is mounted on the shaft of the drive motor 56. The sprocket B61 is connected to the sprocket C143 via a chain B57. When the drive motor 56 is energized, it rotates, driving the sprocket C143 to rotate via the chain B57. This, in turn, drives the sprocket A54 to form a closed, continuous cyclic transmission structure via the chain A53. The two chains A53 continuously circulate, allowing the welded workpieces that fall onto the chains A53 to be transported out through this cyclic transmission.

[0071] like Figure 30As shown, the hydraulic device 11 includes an oil pump motor 132, an oil pump 133, a through-pipe oil valve 134, a top plate oil valve 135, a pressure gauge 136, an oil circuit distributor 137, oil pipe A138, an oil tank 139, oil pipe B140, a guide sleeve 141, a positioning cylinder 142, a sprocket C143, and a return oil pipe 144. The oil pump 133 is bolted to the oil pump motor 132, and the rotating shaft of the oil pump motor 132 is connected to the input shaft of the oil pump 133. The input port of the oil pump 133 is connected to the oil tank 139 through oil pipe B140, and the output port of the oil pump 133 is connected to the oil inlet of the oil circuit distributor 137 through oil pipe A138. The output port of the oil circuit distributor 137 is connected to the through-pipe cylinder 13 and the top plate cylinder 123 through oil pipes. A through-pipe oil valve 134 and a top plate oil valve 135 are installed on the oil distributor 137. The through-pipe oil valve 134 and the top plate oil valve 135 are connected to the power control box 2 via wires. The oil return port of the oil distributor 137 is connected to the oil tank 139 via the oil return pipe 144.

[0072] Before welding, parameters are set via the touchscreen on the control box 9. The welding wire is manually fed into the welding torch 21, and the workpiece tubes to be welded are laid flat on the loading frame 42. The workpiece discs 111 are stacked on the positioning posts 109 in the correct direction. Pressing the start button on the control box 9 triggers a signal from the disc signal controller 130, which detects the workpiece discs 111.

[0073] A: The six lowering cylinders 129 fall simultaneously, causing the three-jaw cylinder 128 to fall as well. The jaws of the three-jaw cylinder 128 are positioned in the center hole of the workpiece disc. The three-jaw cylinder 128 then moves, causing the three jaws to push outward and fix the workpiece disc 111. The lowering cylinders 129 then reset, causing the workpiece disc 111 to rise and disengage from the positioning post 109. The pushing cylinder 112 then moves, sending the six discs 111 onto the tray plate 68 of the flipping clamping device 27. At the same time, the disc signal controller 130 does not detect the signal from the workpiece disc 111. The top plate cylinder 123 then moves, causing the top plate base 124 to move upward, which in turn causes the six top plate columns 125 to lift the discs 111 simultaneously. After the disc signal controller 130 detects the signal, the top plate cylinder 123 stops moving, and the discs 111 remain stationary. The push cylinder 112 returns to its initial position, which in turn drives the gripping beam 108 to return to its original position, causing the three-jaw cylinder 128 to return to directly above the workpiece disc 111. The workpiece disc 111 is placed on the pallet plate 68, where the magnet 75 attracts it and the positioning pin 69 holds it in place. The rotary cylinder 67 actuates, rotating the disc 90 degrees counterclockwise. After the disc is in place, the clamping cylinder 62 actuates, clamping the workpiece disc 111. Simultaneously, the feeding cylinder 30 actuates, feeding the workpiece tube into the support mold 48 and the guide post 38. The pressing cylinder 51 actuates, pressing the workpiece tube with the pulley 31. The tube-rubbing cylinder 32 and the positioning cylinder 142 actuate simultaneously, rotating the pulley 31. Through the friction between the pulley 31 and the workpiece tube, the workpiece tube rotates. The positioning tip on the positioning cylinder 142 inserts into the hole on the workpiece tube, completing the positioning. The pressing cylinder 51 and the tube-rubbing cylinder 32 then reset. Then the pipe-threading cylinder 13 moves, driving the support mold 48 to move the workpiece tube forward. After moving forward for a certain period of time, the material-supporting cylinder 40 moves, driving the material-supporting guide post 38 to retract, avoiding the tube and allowing it to continue moving forward. After the pipe-threading cylinder 13 moves to the position, the tube is inserted into the disc. Then the positioning cylinder 142 resets, and the pipe-threading cylinder 13 begins to retract.

[0074] B: As the pipe-inserting cylinder 13 retracts, the forward-pushing cylinder 23 moves, causing the tooling platform 28 to move inward and be pushed to the welding position. Upon detection of the signal by the positioning controller 29, the tooling platform 28 stops moving. Simultaneously, the left clamping cylinder 88 and the right clamping cylinder 100 move, causing the left center point 92 and the right center point 103 to clamp the round pipe. After clamping, the support cylinder 107 moves to hold the round pipe, and then the torch delivery cylinder 86 moves, causing the welding torch 21 to fall to the weld position. The welding power supply 6 is turned on, and tack welding begins. After tack welding, the clamping cylinder 62 first resets, then the rotary cylinder 67 resets, and then the forward-pushing cylinder 23 resets. The tooling platform 28 returns to its initial position. After the tooling platform 28 returns to its initial position, the rotary motor 95 is energized, driving the main drive shaft 93 to rotate, thereby rotating the round pipe. Simultaneously, the welding power supply 6 is turned on again to begin circumferential welding. While performing circumferential welding, repeat step A to insert another workpiece tube into another set of workpiece discs. After circumferential welding is complete, the welding power supply 6 is turned off, the rotary motor 95 stops, the welding torch 21 rises and resets, the left clamping cylinder 88 and right clamping cylinder 100 simultaneously reset and release the tube, and the support cylinder 107 also resets. The welded workpiece slides down the ramp of the unloading rack 24 onto the two rotating chains A53 of the conveyor device 25, which transport the workpiece out. When the welded workpiece slides onto the conveyor device 25, the outer tube has already been inserted into the disc; repeat step B.

[0075] C: When the last workpiece disc 111 in the right group is picked up, the upper limit controller 125 detects a signal, and the top plate cylinder 123 begins to fall. After falling to the lower limit controller 127, the top plate cylinder 123 stops moving, the switching cylinder 127 opens, and pushes the pallet base plate 126 to the right on the guide rail D118, pushing the other set of stacked workpiece discs 111 to the picking position, completing the switching. The above actions are repeated. At this time, workpiece discs 111 can be stacked on the empty positioning column 109, and the two hoppers can switch between each other, improving production efficiency.
