DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 14 As shown, this embodiment proposes a metal parts welding device, including an equipment frame 1, both ends of the equipment frame 1 are fixedly installed with a support frame 2, and also include a material placement trough 3, a support frame 4, a synchronous drive component, a follower clamping component, a slide rail 5, a welding component and an exhaust gas treatment component. The top of the equipment frame 1 is provided with a material placement trough 3, and two support frames 4 are symmetrically and fixedly installed inside the equipment frame 1. The two support frames 4 are both installed with a synchronous drive component for providing power. The synchronous drive component includes an arc-shaped card slot 6, a driven gear 7, a V-shaped groove 8, and a transmission shaft 9. , driving gear 10 and driving part, arc grooves 6 are provided inside the two supporting frames 4, driven gears 7 are rotatably installed on the two arc grooves 6, V-shaped grooves 8 are provided on the two driven gears 7, and the V-shaped grooves 8 are adapted to the material trough 3. Two transmission shafts 9 are symmetrically and rotatably installed between the two supporting frames 4, and driving gears 10 are fixedly installed at both ends of the two transmission shafts 9. The driving gears 10 at both ends of the two transmission shafts 9 are respectively meshed with the two driven gears 7. The driving part is installed on the equipment frame 1, and is used to simultaneously drive the two transmission shafts 9 to rotate in the same direction.

[0023] It should be added that an observation window 43 for observing the welding situation is installed in front of the equipment frame 1. During the welding process, the welding situation can be observed through the observation window 43, which facilitates timely response in case of unexpected situations. In addition, a removable cover 44 is provided on the top of the equipment frame 1. The cover 44 is located on the upper part of the material trough 3 during the welding process, thereby preventing the smoke generated during the welding process from drifting out from the position of the material trough 3 and affecting the outside world.

[0024] Specifically, when welding two tubular metal parts, first place the two tubular metal parts on the support racks 2 at both ends of the equipment frame 1. If the length of the parts is too long, other support forms can be used, such as adding new brackets at the corresponding positions to support the parts. Then, the two parts are respectively sent into the equipment frame 1 until the ends of the two parts contact each other. The follow-up clamping assembly can be started to fix the relative positions of the two parts and the driven gear 7 respectively, and then the position of the welding assembly is adjusted. After selecting appropriate welding parameters, welding can be started. At this time, the driving unit is started, and the driving unit drives the two transmission shafts 9 at the same time. The two driven gears 7 rotate in the same direction, thereby driving the driving gears 10 at both ends of the transmission shaft 9 to rotate, thereby driving the two driven gears 7 to rotate in the same direction at the same speed, which can drive the two parts to rotate. At the same time, the welding assembly is turned on to weld the two parts, and the exhaust gas treatment assembly is started to treat the exhaust gas generated during welding. After welding, the welding assembly is closed, and the V-groove 8 of the driven gear 7 is moved to the top so that the V-groove 8 is matched with the material feeding trough 3. The machine cover 44 can be opened, and then the follower clamping assembly is loosened to take out the welded parts from the direction of the material feeding trough 3, thereby avoiding damage to the welding position of the parts and increasing the speed of operation.

[0025] It should be noted that, in order to ensure smooth transmission, one driven gear 7 is meshed with two driving gears 10. When driving the driven gear 7 to rotate, when the V-groove 8 on the driven gear 7 moves to the position of one of the driving gears 10, the corresponding driving gear 10 does not mesh with the driven gear 7, but the other driving gear 10 can still drive the driven gear 7 to rotate, and before the V-groove 8 on the driven gear 7 rotates to the position of the other driving gear 10, the previous driving gear 10 will mesh with the driven gear 7, thereby ensuring the continuity of transmission.

[0026] The above, such as Figure 5As shown, the driving part includes a driving frame 11, a driving shaft 12, a first bevel gear 13, a second bevel gear 14 and a first motor 15. The driving frame 11 is fixedly mounted on the equipment frame 1. The driving shaft 12 is rotatably mounted inside the driving frame 11. Two first bevel gears 13 are rotatably mounted on the driving frame 11. The two first bevel gears 13 are respectively fixedly connected to the two transmission shafts 9. Two second bevel gears 14 are fixedly mounted on the driving shaft 12. The two second bevel gears 14 are respectively meshed with the two first bevel gears 13. The first motor 15 is fixedly mounted inside the driving frame 11 and also includes a driving pulley 16, a driven pulley 17 and a transmission belt 18. The output end of the first motor 15 is fixedly mounted with a driving pulley 16, the driving shaft 12 is fixedly mounted with a driven pulley 17, and a transmission belt 18 is sleeved between the driving pulley 16 and the driven pulley 17.

[0027] Specifically, during the welding process of the tubular metal parts, when the parts need to be rotated, the first motor 15 is started, and the first motor 15 drives the active pulley 16 to rotate, and the active pulley 16 drives the driven pulley 17 to rotate through the setting of the transmission belt 18, thereby driving the drive shaft 12 to rotate. Figure 5 The cooperation of the two second bevel gears 14 and the two first bevel gears 13 shown can simultaneously drive the two transmission shafts 9 to rotate at the same speed and in the same direction, thereby driving the parts to rotate.

[0028] like Figure 4 , Figures 7 to 10 As shown, the two synchronous drive assemblies are both equipped with a follower clamping assembly for centering and clamping the tubular metal parts to be welded, the follower clamping assembly comprises an arc tube 19, a first electric cylinder 20, a first fixed plate 21, an arc frame 22, a clamping portion and a positioning portion, the two V-grooves 8 are both fixedly equipped with an arc tube 19, the arc tube 19 coincides with the axis position of the driven gear 7, and a plurality of first electric cylinders 20 are fixedly installed at equal distances on both sides of the two arc tubes 19; a plurality of first electric cylinders 20 are fixedly installed at equal distances on the bottom of the two arc tubes 19, the bottom and both sides of the two arc tubes 19 are both provided with a first fixed plate 21, the first fixed plate 21 is fixedly connected to the first electric cylinder 20, an arc frame 22 is rotatably installed on the two arc tubes 19, the clamping portion is installed on the arc frame 22, and is used to cooperate with the first fixed plate 21 to fix the tubular metal parts to be welded, and a positioning portion is installed on the arc frame 22, and is used to fix the relative position of the arc frame 22 and the arc tube 19.

[0029] Specifically, when the two parts to be welded are placed on the support frame 2, moved to the inside of the equipment frame 1 and docked, the two parts can be fixed separately. At this time, the clamping part on the arc frame 22 is manually rotated to the upper part of the arc cylinder 19 (such as Figure 8As shown), the relative position between the clamping part and the arc tube 19 is fixed by the setting of the positioning part. At this time, the first plurality of first electric cylinders 20 are started first, and the first fixing plates 21 at the corresponding positions are pushed by the first electric cylinders 20 to fix the parts. The bottom and both sides of the arc tube 19 are provided with fixing plates, which can quickly fix the parts. The parts are further fixed by the setting of the clamping part, so that the parts are more stable when rotating during the welding process. After the welding is completed, the clamping part is retracted, and the arc frame 22 is rotated to the lower part of the arc tube 19 (as shown in FIG. Figure 7 As shown), after moving the V-groove 8 on the driven gear 7 upward, the welded parts can be taken out from the upper part of the equipment frame 1.

[0030] The above, such as Figure 8 , Fig.10 As shown, the clamping part includes a second electric cylinder 23, a placement groove 24 and a second fixed plate 25. A plurality of second electric cylinders 23 are fixedly installed on the two arc frames 22 at equal distances. The plurality of second electric cylinders 23 are staggered with the plurality of first electric cylinders 20. A plurality of placement grooves 24 are opened at equal distances inside the two arc frames 22. The plurality of placement grooves 24 correspond one-to-one to the plurality of second electric cylinders 23. A second fixed plate 25 is arranged in each placement groove 24. The output ends of the plurality of second electric cylinders 23 are respectively fixedly connected to the plurality of second fixed plates 25.

[0031] Specifically, when fixing the parts, after the arc frame 22 is rotated to the upper part of the arc tube 19, the second electric cylinder 23 can be opened, and the second electric cylinder 23 drives the second fixing plate 25 to move until the second fixing plate 25 contacts the parts, and then the second electric cylinder 23 can be closed and locked, and the parts can be fixed in cooperation with the first fixing plate 21. After the welding is completed, the second electric cylinder 23 is retracted, and the second fixing plate 25 is moved into the placement groove 24, and the arc frame 22 can be rotated to the bottom of the arc tube 19. The second fixing plate 25 entering the placement groove 24 does not interfere with the rotation of the arc frame 22.

[0032] It should be added that in order to adapt to tubular metal parts, the second fixing plate 25 and the first fixing plate 21 are both set to be arc-shaped, thereby increasing the force-bearing area and avoiding crushing of thin-walled pipes during processing, thereby avoiding unnecessary waste, and a plurality of anti-slip grooves are evenly spaced on the first fixing plate 21 and the second fixing plate 25 to improve the fixing effect of the parts.

[0033] The above, such as Fig. 9As shown, the positioning part includes a positioning frame 26, a positioning block 27, a spring 28 and a positioning groove 29. Two positioning frames 26 are symmetrically and fixedly installed at both ends of the two arc-shaped frames 22. A positioning block 27 is slidably installed inside each positioning frame 26. A spring 28 is fixedly installed between each positioning block 27 and the positioning frame 26. Two positioning grooves 29 are provided on both sides of the two arc-shaped cylinders 19, and the multiple positioning grooves 29 are respectively adapted to the multiple positioning blocks 27.

[0034] Specifically, when the arc frame 22 needs to be rotated to the upper part of the arc tube 19, the arc frame 22 rotates around the axis position of the arc tube 19. At this time, the positioning block 27 and the positioning groove 29 move relative to each other, the spring 28 is compressed, and the positioning block 27 enters the interior of the positioning frame 26. The end of the positioning block 27 slides with the arc tube 19 during the rotation of the arc frame 22 until the arc frame 22 is rotated 180° and moved to the upper part of the arc tube 19. At this time, the positioning block 27 corresponds to the positioning groove 29, and the spring 28 releases the pressure to push the positioning block 27 into the positioning groove 29, thereby fixing the position of the arc frame 22.

[0035] like Fig.12 , Fig.13 As shown, two slide rails 5 are symmetrically and fixedly installed inside the equipment frame 1, and a welding assembly is installed between the two slide rails 5 for welding tubular metal parts. The welding assembly includes a sliding frame 30, a third electric cylinder 31, a sliding frame 32, a screw 33, a second motor 34, a nut 35 and a welding part. The sliding frame 30 is slidably installed between the two slide rails 5, and the third electric cylinder 31 is fixedly installed inside the equipment frame 1. The output end of the third electric cylinder 31 is fixedly connected to the sliding frame 30, and the sliding frame 32 is slidably installed on the sliding frame 30. The screw 33 is rotatably installed inside the sliding frame 30. The second motor 34 is fixedly installed inside the sliding frame 30, and the output end of the second motor 34 is fixedly connected to the screw 33. A nut 35 is threadedly sleeved on the screw 33, and the nut 35 is fixedly connected to the sliding frame 32. The welding part is installed on the sliding frame 32 for welding tubular metal parts.

[0036] Specifically, before welding the metal parts, the working position of the welding part is first determined according to the fixed position of the parts, and the third electric cylinder 31 is started. The third electric cylinder 31 drives the sliding frame 30 to move up and down along the direction of the slide rail 5, and then the second motor 34 is started. The second motor 34 drives the screw 33 to rotate, and the screw 33 drives the nut 35 to move, so that through the setting of the nut 35, the sliding frame 32 is driven to move left and right on the sliding frame 30, thereby driving the welding part to move. After the welding part is moved to the working position, the second motor 34 and the third electric cylinder 31 can be closed and locked.

[0037] It should be supplemented that two guide rods 45 are also installed on the sliding frame 30. The guide rods 45 are slidably matched with the sliding frame 32. In the process of adjusting the position of the welding part, the stability of the sliding frame 32 during sliding can also be improved.

[0038] The above, such as Fig.13 As shown, the welding part includes a welding device body 36, a positioning frame 37 and a fourth electric cylinder 38. The positioning frame 37 is slidably installed on the sliding frame 32, wherein the welding device body 36 is fixedly installed on the positioning frame 37, and the fourth electric cylinder 38 is fixedly installed inside the sliding frame 32, and the output end of the fourth electric cylinder 38 is fixedly connected to the positioning frame 37.

[0039] Specifically, in the process of adjusting the welding device body 36, the fourth electric cylinder 38 is started, and the fourth electric cylinder 38 pushes the adjustment frame 37 to move, thereby driving the welding device body 36 to move, thereby adjusting the distance between the welding device and the parts to be welded. After adjustment, the fourth electric cylinder 38 can be closed and locked.

[0040] like Fig.14 As shown, a waste gas treatment component is installed inside the equipment frame 1 for collecting waste gas generated during the welding process of tubular metal parts. The waste gas treatment component includes a collecting box 39, a mesh plate 40, an exhaust pipe 41 and a blower 42. The collecting box 39 is fixedly installed inside the equipment frame 1, a mesh plate 40 is fixedly installed on the top of the collecting box 39, the exhaust pipe 41 is connected to the collecting box 39, and the blower 42 is fixedly installed on the equipment frame 1, and the input end of the blower 42 is connected to the exhaust pipe 41.

[0041] Specifically, since the welding process will produce gases and smoke containing various oxide particles, the size of the particles directly affects their harmfulness. The smaller the particles, the more dangerous they are. In addition, many of these processing processes will produce gases (the most common ones are carbon dioxide and ozone, of course there are others, which will not be elaborated here). If the ventilation is not good, it will cause harm to the human body and the surrounding environment. Therefore, it is necessary to treat the gases generated during welding, and connect the air outlet of the blower 42 to the processing equipment. Start the blower 42 during the welding process. The blower 42 draws air from the collection box 39 through the exhaust pipe 41, so that the exhaust gas generated during the welding process enters the collection box 39 through the mesh plate 40, and enters the blower 42 along the exhaust pipe 41, and then enters the processing equipment for treatment. The treated exhaust gas can be discharged after being tested to be harmless.

[0042] The working principle or usage process of this application is: When welding two tubular metal parts, first place the two tubular metal parts on the support racks 2 at both ends of the equipment rack 1 respectively. If the length of the parts is too long, other support forms can be used, such as adding new brackets at the corresponding positions to support the parts, and then the two parts are sent into the equipment rack 1 respectively until the ends of the two parts contact each other, and the two parts can be fixed.

[0043] At this time, manually rotate the second electric cylinder 23 on the arc frame 22 to the upper part of the arc tube 19 (such as Figure 8 As shown in the figure, the arc frame 22 rotates around the axis position of the arc tube 19. At this time, the positioning block 27 and the positioning groove 29 move relative to each other, the spring 28 is compressed, and the positioning block 27 enters the interior of the positioning frame 26. The end of the positioning block 27 slides with the arc tube 19 during the rotation of the arc frame 22 until the arc frame 22 is rotated 180° and moved to the upper part of the arc tube 19. At this time, the positioning block 27 corresponds to the positioning groove 29, and the spring 28 releases the pressure to push the positioning block 27 into the positioning groove 29, thereby fixing the position of the arc frame 22.

[0044] When fixing the parts, first start multiple first electric cylinders 20, and push the first fixing plates 21 at the corresponding positions through the first electric cylinders 20 to fix the parts. The bottom and both sides of the arc tube 19 are provided with fixing plates, which can quickly fix the parts. At the same time, start the second electric cylinder 23, and the second electric cylinder 23 drives the second fixing plate 25 to move until the second fixing plate 25 contacts the parts. Then the second electric cylinder 23 can be closed and locked, and the parts can be fixed in cooperation with the first fixing plate 21. The second fixing plate 25 and the first fixing plate 21 are both set to be arc-shaped, thereby increasing the force-bearing area, avoiding crushing of thin-walled pipes during processing, thereby avoiding unnecessary waste, and multiple anti-slip grooves are evenly spaced on the first fixing plate 21 and the second fixing plate 25, thereby improving the fixing effect of the parts.

[0045] Then, the position of the welding device body 36 is adjusted according to the docking position between the two parts, and the third electric cylinder 31 is started. The third electric cylinder 31 drives the sliding frame 30 to move up and down along the direction of the slide rail 5, and then the second motor 34 is started. The second motor 34 drives the screw 33 to rotate, and the screw 33 drives the nut 35 to move, so that through the setting of the nut 35, the sliding frame 32 is driven to move left and right on the sliding frame 30, thereby driving the sliding frame 32 to move, and at the same time, the fourth electric cylinder 38 is started. The fourth electric cylinder 38 pushes the adjustment frame 37 to move, thereby driving the welding device body 36 to move, so as to adjust the distance between the welding device and the parts to be welded. After adjusting the position of the welding device, the second motor 34, the third electric cylinder 31 and the fourth electric cylinder 38 can be closed and locked.

[0046] At this time, the parts can be welded by selecting appropriate welding parameters. In the process of welding the tubular metal parts, the parts need to be rotated. At this time, the first motor 15 is started, and the first motor 15 drives the active pulley 16 to rotate. The active pulley 16 drives the driven pulley 17 to rotate through the setting of the transmission belt 18, thereby driving the drive shaft 12 to rotate. Figure 5 The cooperation of the two second bevel gears 14 and the two first bevel gears 13 shown in the figure can simultaneously drive the two transmission shafts 9 to rotate at the same speed and in the same direction, thereby driving the driving gears 10 at both ends of the transmission shafts 9 to rotate, thereby driving the two driven gears 7 to rotate at the same speed and in the same direction, thereby driving the two parts to rotate and weld at the same time.

[0047] During the welding process, the air outlet of the blower 42 is connected to the processing equipment, and the blower 42 is started during the welding process. The blower 42 draws air in the collection box 39 through the exhaust pipe 41, so that the exhaust gas generated during the welding process enters the collection box 39 through the mesh plate 40, and enters the blower 42 along the exhaust pipe 41, and then enters the processing equipment for treatment. The treated exhaust gas can be discharged after being tested to be harmless.

[0048] After welding is completed, the cover 44 is removed, the second electric cylinder 23 is retracted, and the second fixing plate 25 is moved into the placement groove 24, and the arc frame 22 can be rotated to the bottom of the arc cylinder 19 (such as Figure 7 As shown), the second fixed plate 25 entering the placement groove 24 does not interfere with the rotation of the arc frame 22, and then the V-groove 8 on the driven gear 7 is moved upward so that the V-groove 8 is adapted to the material placement groove 3, and the first electric cylinder 20 is retracted, and the welded parts are taken out from the direction of the material placement groove 3, thereby avoiding damage to the welding position of the parts.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
