[0018] A flange welding device of the present invention, compared with the prior art, has the beneficial effects as follows:

[0019] 1. By installing the clamping mechanism at the bottom of the flipping table, when the flange body is placed on the flipping table, the clamping mechanism can fix the flange body on the flipping table, so as to realize the synchronous movement of the flange body and the flipping table; by connecting one end of the two flipping shafts to both sides of the flipping table respectively, and connecting the other end of the two flipping shafts to the two lifting frames rotatably, it is realized that the two lifting frames support the flipping table through the two flipping shafts respectively, so as to realize the synchronous rotation of the flipping table and the flange body, so that the first welding mechanism and the second welding mechanism can weld different positions of the flange body, and further realize that the overall welding of the flange body can be completed with only one clamping, so as to improve the welding efficiency of the flange body.

[0020] 2. By arranging the first threaded hole through the first adjustment table and making the first lead screw pass through the first threaded hole, the first lead screw is threadedly connected to the first adjustment table, so as to realize that by rotating the first lead screw, the first lead screw drives the first adjustment table to move, and further adjust the position of the first adjustment table.

[0021] 3. By installing the first electric push rod on the first adjusting platform, connecting the first electric push rod with the second adjusting platform, and installing the first welding mechanism on the second adjusting platform, the second adjusting platform can support the first welding mechanism, so that the first electric push rod can drive the second adjusting platform to move, and then the first welding mechanism and the second adjusting platform can move synchronously to adjust the position of the first welding mechanism to increase the welding range of the first welding mechanism.

[0022] 4. By passing the second lead screw through the second threaded hole of the first lifting plate and installing the first welding gun on the end of the first lifting plate away from the first welding frame, the first lead screw is threadedly connected to the first lifting plate, so that when the second motor drives the second lead screw to rotate, the second lead screw can drive the first lifting plate to move up and down, thereby adjusting the height of the first welding gun, so that the first welding gun can weld the flange body.

[0023] 5. By installing the second electric push rod on the second workbench, connecting the second electric push rod with the third adjusting table, and installing the second welding mechanism on the third adjusting table, the third adjusting table can support the second welding mechanism, so that the second electric push rod can drive the third adjusting table and the second welding mechanism to move, so as to adjust the position of the second welding mechanism and increase the welding range of the second welding mechanism.

[0024] 6. By passing the third lead screw through the second threaded hole of the second lifting plate and installing the second welding gun at the end of the second lifting plate away from the second welding frame, the first lead screw and the second lifting plate are threadedly connected, so that when the third motor drives the third lead screw to rotate, the third lead screw can drive the second lifting plate to move up and down, thereby adjusting the height of the second welding gun to facilitate the second welding gun to weld the flange body.

[0025] 7. By installing the fourth motor on a slide and connecting the first gear to the fourth output shaft of the fourth motor, the slide supports the fourth motor, so that the fourth motor can drive the first gear to rotate; by installing the rack on the ground and meshing the first gear with the rack, when the fourth motor drives the first gear to rotate, the first gear can mesh with the rack to move, thereby adjusting the position of the slide and the lifting mechanism.

[0026] 8. When the flange body is ready to be rotated, the fifth motor is started to drive the second gear to rotate, so that the second gear drives the third gear to rotate, and then drives the flip shaft, the flip table and the flange body to rotate. Then, the positioning anti-rotation mechanism is started, so that the two positioning anti-rotation mechanisms clamp the two flip shafts respectively, thereby preventing the flip shafts from rotating again, thereby improving the stability of the flange body.

[0027] 9. By embedding the rotation axis into the first clamping groove and the second clamping groove, when the fourth lead screw drives the first clamping plate and the second clamping plate to move relatively, the first clamping plate and the second clamping plate cooperate to clamp the rotation axis, thereby preventing the rotation axis from rotating and improving the stability of the flange body.

[0028] 10. When preparing to place the flange body on the turntable, rotate the rotating plate of the shaft, so that the rotating plate drives the three clamping rods to move away from the center line of the rotating plate through the three connecting rods, thereby driving the three clamping wheels to move away from the center line of the rotating plate, so as to increase the distance between the three clamping wheels, and then facilitate placing the flange body on the turntable; when the clamping rod moves away from the center line of the rotating plate, the first spring is in a stretched state; then, place the flange body on the turntable and release the rotating plate; at this time, the first spring resets and drives the clamping rod and the clamping wheel to move towards the center line of the rotating plate, so that at least part of the flange body can be embedded in the three clamping grooves at the same time, and then the three clamping wheels cooperate to fix the flange body on the turntable to ensure that the turntable can drive the flange body to move and rotate.

[0029] 11. When preparing to rotate the rotating plate to facilitate placing the flange body on the turntable, first move the turntable above the connecting head; then, start the two lifting mechanisms, so that the two lifting mechanisms cooperate to move the turntable, the rotating plate and the connecting platform downward, so that the connecting head can pass through the guiding hole and be embedded in the connecting hole; then, start the seventh motor, so that the seventh motor drives the rotating shaft and the connecting hole through the first bevel gear and the second bevel gear, thereby driving the connecting platform and the rotating plate to rotate, and then the rotating plate drives the three clamping rods to move away from the center line of the rotating plate through the three connecting rods, so as to facilitate placing the flange body on the turntable. After the flange body has been placed on the turntable, start the two lifting mechanisms, so that the two lifting mechanisms cooperate to drive the turntable to move upward (the upward movement distance does not need to be too large), so that the connecting head moves out of the connecting hole and the guiding hole; at this time, the first spring resets and drives the clamping rod and the clamping wheel to move towards the center line of the rotating plate, so that the three clamping wheels cooperate to clamp the flange body. Since the fourth adjusting platform can move along the two first optical bars, when the rotating plate and the connecting platform move downward, the connecting head can first be embedded in the guiding hole, and then the fourth adjusting platform moves along the two first optical bars to ensure that the connecting head is embedded in the connecting hole, thereby improving the user experience of the product. Moreover, when the connecting head moves out of the connecting hole and the guiding hole, the four second springs cooperate to correct the position of the fourth adjusting platform to facilitate the subsequent embedding of the connecting head into the connecting hole again.

[0049] By installing the first adjustment mechanism 12 on the first workbench 10, connecting the first adjustment table 13 to the first adjustment mechanism 12, and installing the pressing mechanism 14 on the first adjustment table 13, the first adjustment table 13 supports the pressing mechanism 14, so that the first adjustment mechanism 12 can drive the first adjustment table 13 and the pressing mechanism 14 to move, and then adjust the position of the pressing mechanism 14; by installing the second adjustment mechanism 15 on the first adjustment table 13, placing the first welding mechanism 16 on the first adjustment table 13, and connecting the first welding mechanism 16 to the second adjustment mechanism 15, the second adjustment mechanism 15 can drive the first welding mechanism 16 to move on the first adjustment table 13, so as to adjust the position of the first welding mechanism 16; by installing the third adjustment mechanism 17 on the second workbench 11, placing the second welding mechanism 18 on the second workbench 11, and connecting the second welding mechanism 18 to the third adjustment mechanism 17, the third adjustment mechanism 17 can drive the second welding mechanism 18 to move on the second workbench 11, so as to adjust the position of the second welding mechanism 18.

[0050] When specifically using the product, first start the clamping mechanism 24 to open the clamping mechanism 24; then, place the flange body 31 on the turntable 22; afterwards, start the clamping mechanism 24 to clamp the clamping mechanism 24 with the flange body 31; afterwards, start the moving mechanism 19 to drive the lifting mechanism 20, the lifting frame 21, the turntable 22 and the flange body 31 placed on the turntable 22 to move towards the first workbench 10; when the flange body 31 moves above the first workbench 10, start the lifting mechanism 20 to drive the lifting frame 21 and the turntable 22 to move downward, so that at least part of the flange body 31 (the position of the flange body 31 to be welded) is placed on the first workbench 10; afterwards, start the first adjusting mechanism 12 to drive the first adjusting table 13, the pressing mechanism 14 and the first welding mechanism 16 to move, so that the pressing mechanism 14 is located above the flange body 31; afterwards, start the pressing mechanism 14 to press the flange body 31, so as to avoid the situation that the positions to be welded of the flange body 31 are staggered, and thus facilitate subsequent welding of this position; afterwards, start the first welding mechanism 16 to weld the side surface (top) of the flange body 31 facing away from the turntable 22.

By installing the L-shaped first mounting bracket 252 on the fourth adjustment table 250, rotatably connecting one end of the rotating shaft 253 to the top of the first mounting bracket 252, and rotatably connecting the other end of the rotating shaft 253 to the fourth adjustment table 250, so as to realize that the fourth adjustment table 250 and the first mounting bracket 252 cooperate to support the rotating shaft 253, thereby enabling the rotating shaft 253 to rotate within the first mounting bracket 252; by connecting the connector 254 in a certain direction to one end of the rotating shaft 253, so as to realize the synchronous rotation of the rotating shaft 253 and the connector 254. By installing the seventh motor 255 on the fourth adjustment table 250 and connecting the second bevel gear 257 to the seventh output shaft of the seventh motor 255, so as to realize that the fourth adjustment table 250 supports the seventh motor 255, thereby enabling the seventh motor 255 to drive the second bevel gear 257 to rotate; by sleeving the first bevel gear 256 on the outside of the rotating shaft 253 and meshing the first bevel gear 256 with the second bevel gear 257, so as to realize that when the seventh motor 255 drives the second bevel gear 257 to rotate, the second bevel gear 257 meshes with the first bevel gear 256 to rotate, thereby realizing the rotation of the rotating shaft and the connector 254. By connecting the connecting table 258 to the center of the rotating plate 241, so as to realize the synchronous rotation of the rotating plate 241 and the connecting table 258; by providing a connecting hole 259 in a certain direction in the connecting table 258, providing a guiding hole 260 with a trapezoidal cross-section at the bottom of the connecting table 258, and making the guiding hole 260 communicate with the connecting hole 259, so as to realize that the connector 254 can pass through the guiding hole 260 and be embedded in the connecting hole 259, thereby reducing the difficulty of the connector 254 being embedded in the connecting hole 259.

[0081] With the above structure, when preparing to rotate the rotating plate 241 to facilitate the placement of the flange body 31 on the turning table 22, first move the turning table 22 above the connecting head 254; then, start the two lifting mechanisms 20, and make the two lifting mechanisms 20 cooperate with the turning table 22, the rotating plate 241 and the connecting table 258 to move downward, so that the connecting head 254 can pass through the guiding hole 260 and be embedded into the connecting hole 259; then, start the seventh motor 255, and make the seventh motor 255 drive the rotating shaft 253 and the connecting hole 259 through the first bevel gear 256 and the second bevel gear 257, thereby driving the connecting table 258 and the rotating plate 241 to rotate, and further making the rotating plate 241 drive the three clamping rods 243 to move away from the midline direction of the rotating plate 241 through the three connecting rods 244, so as to facilitate the placement of the flange body 31 on the turning table 22. When the flange body 31 has been placed on the turning table 22, start the two lifting mechanisms 20, and make the two lifting mechanisms 20 cooperate to drive the turning table 22 to move upward (the upward moving distance does not need to be too large), so that the connecting head 254 is removed from the connecting hole 259 and the guiding hole 260; at this time, the first spring 247 is reset, and will drive the clamping rod 243 and the clamping wheel 245 to move towards the midline direction of the rotating plate 241, so that the three clamping wheels 245 cooperate to clamp the flange body 31. Since the fourth adjusting table 250 can move along the two first optical bars 249, when the rotating plate 241 and the connecting table 258 move downward, the connecting head 254 can first be embedded into the guiding hole 260, and then make the fourth adjusting table 250 move along the two first optical bars 249 to ensure that the connecting head 254 is embedded into the connecting hole 259, thereby improving the user experience of the product. Moreover, when the connecting head 254 is removed from the connecting hole 259 and the guiding hole 260, the four second springs 251 cooperate to correct the position of the fourth adjusting table 250, so as to facilitate the subsequent embedding of the connecting head 254 into the connecting hole 259 again.

[0082] Specifically, the flange body 31 is hoisted at three points by three steel wire ropes, so as to place the flange body 31 on the turning table 22. At this time, the hoisting positions of the steel wire ropes and the flange body 31 are located outside the turning table 22; when the three clamping wheels 245 clamp the flange body 31, the steel wire ropes are disassembled.

[0083] Specifically, when the three clamping wheels 245 clamp the flange body 31, in order to improve the stability of the flange body 31, the clamping rod 243 can be fixed on the rotating plate 241 by a setscrew.

[0084] Specifically, since the seventh motor 255 is installed on the fourth adjusting table 250 and two first optical bars 249 pass through the fourth adjusting table 250, the seventh motor 255 moves synchronously along the two first optical bars 249 with the fourth adjusting table 250, so as to realize the movement of the seventh motor 255 within a small range. Compared with installing the driving device on the turning table 22 (indirectly or directly installed on the turning table 22), it can avoid the synchronous movement and rotation of the driving device and the turning table 22, thus facilitating the wiring of the driving device and reducing the assembly difficulty of the product.
