Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and more specifically, particularly relates to an automatic flange welding robot. Background Art

[0002] The flange automatic welding robot is a robot system specially designed for automatic welding of flanges. It can achieve efficient, accurate and safe welding, improve production efficiency and welding quality. These robots have precise control systems, can adapt to flanges of various shapes, sizes and materials, and perform a variety of welding methods. Through automated welding, the flange automatic welding robot can reduce labor costs and production cycles, improve consistency and quality stability, and is suitable for the needs of flange welding in various industrial fields.

[0003] At present, the existing welding robot (such as patent number: CN109175824B) discloses a flange automatic welding robot, which belongs to the field of welding equipment technology, including a material storage mechanism, a material transfer mechanism, a limit mechanism and a welding mechanism, the material transfer mechanism includes a mounting plate, a lifting assembly, a feeding assembly and a clamping assembly, the clamping assembly includes a driving component and two clamping components, the two clamping components have the same structure and both include a supporting plate and a rotating member, and the supporting plate is an L-shaped structure. The present invention can flip the flange 180 degrees through the rotating member to complete the flipping operation of the flange, without the need for the worker to manually flip the operation, and can realize the automatic feeding operation of the flange through the material storage mechanism and the material transfer mechanism, and can automatically rotate the flange through the rotating assembly, so that the notch on the flange can face the welding machine, which is convenient for the welding machine to perform welding operations by dropping the notch of the flange.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] 1. During the welding process, the welding robot will heat the welding wire to a molten state, and then use the nozzle to align the welding wire with the weld of the workpiece to be welded to fill it. At this time, the nozzle may gradually wear out due to contact with the workpiece, high temperature and corrosion. Therefore, we need to replace the nozzle frequently. When the nozzle needs to be replaced, the staff needs to shut down the welding robot. After the welding robot cools down, the nozzle of the welding robot can be replaced. This will increase the downtime of the production line, affect the continuity of welding, and reduce production efficiency.

[0006] 2. When the flange automatic welding robot is performing welding work, some sparks often fly. These sparks are usually molten metal particles. These metal particles may adhere to the rotating mechanism of the flange automatic welding robot when flying. After the particles cool down, they will be fixed on the rotating mechanism to form bulges, which reduces the surface smoothness of the rotating mechanism, affects the rotation flexibility and stability of the rotating parts, and causes unstable operation or jamming.

[0007] 3. Vibration may occur during the welding process of the flange automatic welding robot. The motor inside the welding robot may be displaced due to the vibration during welding, thereby reducing the output efficiency of the motor.

[0008] Therefore, in view of this, the existing structure and defects are studied and improved, and a flange automatic welding robot is provided to achieve a more practical purpose. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, a rotating chassis is provided and a moving path of the welding robot is set by programming. The welding head of the automatic flange welding robot can be accurately moved to a position directly above the rotating chassis, and the welding head of the automatic flange welding robot contacts the upper surface of the corresponding nozzle. At this time, motor 2 is started, and motor 2 drives the short rod and the corresponding rotating bevel gear to rotate, and the rotating bevel gear drives the corresponding four meshing bevel gears to rotate. At this time, the connecting rod drives all the meshing bevel gears to rotate synchronously. Since the rotating bevel gear is meshed with the meshing bevel gear, the four rotating bevel gears fixedly connected to the support column drive the rotating chassis to rotate synchronously. At this time, the nozzle on the rotating chassis also starts to rotate synchronously, and the nozzle in contact with the welding head of the automatic flange welding robot will continuously be threadedly engaged with the welding head of the automatic flange welding robot due to rotation, and finally be installed on the welding head of the automatic flange welding robot, so as to achieve the purpose of automatically installing the nozzle and facilitate the process of installing the nozzle.

[0022] In the present invention, a rotating disk is provided, and when the nozzle needs to be replaced, the old nozzle on the welding head is aligned with a rotating chassis without a nozzle, and the motor 2 is controlled to output in reverse. At this time, since the limit blocks at both ends of the old nozzle are supported by four limit rods, the rotating chassis drives the old nozzle to rotate in the opposite direction, so that the old nozzle directly detaches from the welding head of the flange automatic welding robot. At this time, motor 1 is started, and motor 1 drives the meshing threaded rod to rotate, and the meshing gear will rotate synchronously with the meshing threaded rod.

[0023] In the present invention, a glass baffle is provided. When welding is to be carried out, motor three is started. At this time, the long rod and two rotating gears of motor three rotate. Since the two gear bars on the lifting frame are meshed with the rotating gear, when the rotating gear rotates, the lifting frame will drive the glass baffle to rise until it rises to a suitable distance, and then motor three is turned off. At this time, the glass baffle will not affect the visual sensor of the flange automatic welding robot, but will also block the sparks flying during welding, thereby avoiding the metal particles from adhering to the rotating mechanism to form bulges, reducing the surface smoothness of the rotating mechanism, affecting the rotation flexibility and stability of the rotating parts, and allowing the rotating shaft to rotate stably.

[0024] In the present invention, a fixing frame three is provided, the fixing frame three is stably fixed on the base, and the motor three is fixedly connected to the fixing frame three.

[0038] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

A rotating column 11 is arranged at the lower end of the rotating disk 6, and the upper surface of the rotating column 11 is fixedly connected with the lower surfaces of the four support columns 21. By programming and setting a moving path of the welding robot, the welding head of the flange automatic welding robot can be accurately moved to a position just above a rotating chassis 15, and the welding head of the flange automatic welding robot contacts the upper surface of the corresponding nozzle 4. At this time, the motor 23 is started, and the motor 23 drives the short rod 24 and the corresponding rotating bevel gear 22 to rotate, and the rotating bevel gear 22 drives the corresponding four meshing The meshing bevel gear 27 rotates, and the connecting rod 26 drives all the meshing bevel gears 27 to rotate synchronously. Since the rotating bevel gear 22 meshes with the meshing bevel gear 27, the four rotating bevel gears 22 fixedly connected to the support column 21 drive the rotating chassis 15 to rotate synchronously. At this time, the nozzle 4 on the rotating chassis 15 also starts to rotate synchronously. The nozzle 4 in contact with the welding head of the flange automatic welding robot will continuously be threadedly engaged with the welding head of the flange automatic welding robot due to the rotation, and finally installed on the welding head of the flange automatic welding robot, so as to achieve the purpose of automatically installing the nozzle 4 and make the process of installing the nozzle 4 convenient.

[0040] A short rod 24 is fixedly connected to the upper surface of the rotating column 11, and the upper surface of the short rod 24 is fixedly connected to the rotating bevel gear 22. The rotating bevel gear 22 is vertically meshed with meshing bevel gears 27 facing the four support columns 21. When the nozzle 4 needs to be replaced, the old nozzle on the welding head is aligned with a rotating chassis 15 without a nozzle 4, and the control motor 23 is reversely output. At this time, since the limit blocks 17 at both ends of the old nozzle are supported by the four limit rods 16, the rotating chassis 15 drives the old nozzle to rotate in the opposite direction, so that the old nozzle is directly separated from the welding head of the flange automatic welding robot. At this time, the welding head of the automatic flange welding robot is started. Motor 1 7, motor 1 7 drives the meshing threaded rod 12 to rotate, and the meshing gear 13 will rotate synchronously with the meshing threaded rod 12. At this time, the meshing gear 13 drives the rotating disk 6 to rotate through the fixed frame 1 8. When the new nozzle of the rotating chassis 15 is aligned with the welding head of the flange automatic welding robot, the motor 2 23 is restarted to make the new nozzle re-threaded on the welding head of the flange automatic welding robot, so as to achieve the purpose of automatically replacing the nozzle 4, so that there is no need for cooling and waiting during the replacement process, which avoids increasing the downtime of the production line, affecting the continuity of welding, and improving production efficiency.

[0041] Each meshing bevel gear 27 is fixedly connected to a connecting rod 26 in a direction away from the short rod 24, and a side of each connecting rod 26 away from the short rod 24 is also fixedly connected to the meshing bevel gear 27, and each meshing bevel gear 27 is vertically meshed with the corresponding rotating bevel gear 22, and four support blocks 20 corresponding to the positions of the connecting rods 26 are fixedly connected to the upper surface of the rotating column 11, and each support block 20 is penetrated by a hole three 25 corresponding to the position of the connecting rod 26, and each connecting rod 26 is rotationally connected to the corresponding support block 20 through the hole three 25, and the support block 20 is rotationally connected to the connecting rod 26, so that the meshing bevel gears 27 at both ends of the connecting rod 26 have a more stable transmission effect when meshing and transmitting the rotating bevel gear 22, thereby avoiding the problems of poor meshing, tooth skipping, sliding, or intermittent transmission of the meshing bevel gears 27 during transmission, and improving the meshing transmission effect between the bevel gears.

[0042] A slot 28 is provided through the upper surface of the rotating column 11, and a fixed frame 2 14 is fixedly connected to the lower surface of the rotating column 11, a motor 23 is fixedly connected to the interior of the fixed frame 14, and the output port of the motor 23 is fixedly connected to the lower surface of the short rod 24 through the slot 28, the fixed frame 14 is fixedly connected to the meshing gear 13, and the right end of the meshing gear 13 is meshingly connected to the meshing threaded rod 12, the front and rear ends of the meshing threaded rod 12 are rotatably connected to the inner wall of the fixed block 5, and the lower surface of the fixed frame 2 14 is rotatably connected to the inner wall of the fixed block 5, a hole 9 is provided through the rear surface of the fixed block 5, and a fixed frame 8 is fixedly connected to the front surface of the fixed block 5, and a motor 7 is fixedly connected to the front surface of the fixed frame 8, and the output port of the motor 7 passes through the hole 9 and the meshing gear 13. The rear surface of the threaded rod 12 is rotatably connected, and a groove 29 is provided on the upper surface of the base 3, and a lifting frame 34 is arranged inside the groove 29, and a glass baffle 35 is fixedly connected inside the lifting frame 34, and two long grooves 37 are provided on the lower surface of the lifting frame 34, and the lifting frame 34 is movably connected to two limiting columns 38 through the long grooves 37, and the lower surface of each limiting column 38 is fixedly connected to the inner wall of the base 3. When the motor 31 drives the lifting frame 34 and the glass baffle 35 to rise, the two limiting columns 38 are both inside the lifting frame 34. The lifting frame 34 can only move along the limiting columns 38 when lifting, so that the lifting frame 34 is more stable when rising, avoiding the position displacement of the lifting frame 34 when rising, and improving the stability of the lifting frame 34 when rising.

[0043] The front surface of the lifting frame 34 is fixedly connected with two parallel gear bars 39, and each gear bar 39 is meshed with a rotating gear 33. A long rod 30 is arranged inside the groove 29. Both ends of the long rod 30 are rotatably connected to the inner wall of the base 3, and the long rod 30 is fixedly connected to the two rotating gears 33. When welding work is to be performed, the motor three 31 is started. At this time, the long rod 30 and the two rotating gears 33 driven by the motor three 31 rotate. Since the two gear bars 39 on the lifting frame 34 are meshed with the rotating gear 33, when the rotating gear 33 rotates, the lifting frame 34 will drive the glass baffle 35 to rise. When it rises to a suitable distance, the motor three 31 is turned off. At this time, the glass baffle 35 will not affect the visual sensor of the flange automatic welding robot, but will also block the sparks splashed during welding, thereby avoiding the metal particles from adhering to the rotating mechanism to form bulges, reducing the surface smoothness of the rotating mechanism, affecting the rotation flexibility and stability of the rotating parts, so that the rotating shaft 2 can rotate stably.

[0044] A hole four 36 is formed through the right surface of the base 3, and a fixing frame three 32 is fixedly connected to the right surface of the base 3, and a motor three 31 is fixedly connected to the right surface of the fixing frame three 32. The output port of the motor three 31 passes through the hole four 36 and is fixedly connected to the right surface of the long rod 30. The fixing frame three 32 is stably fixed on the base 3, and the motor three 31 is fixedly connected to the fixing frame three 32. When the device body 1 is welded, the base 3 is driven to vibrate. Since the motor three 31 is stably fixed on the fixing frame three 32, the motor three 31 will not shift in position. The fixing frame three 32 provides a stable output environment for the motor three 31, and provides stability for the motor three 31 during output.

[0045] Working principle:

[0046] The first step is to set a moving path of the welding robot through programming. The welding head of the flange automatic welding robot can accurately move to a position directly above a rotating chassis 15, and the welding head of the flange automatic welding robot contacts the upper surface of the corresponding nozzle 4. At this time, start motor 23, and motor 23 drives the short rod 24 and the corresponding rotating bevel gear 22 to rotate the new nozzle. The rotating bevel gear 22 drives the corresponding four meshing bevel gears 27 to rotate. At this time, the connecting rod 26 drives all the meshing bevel gears 27 to rotate synchronously. Since the rotating bevel gear 22 is meshed with the meshing bevel gear 27, the four rotating bevel gears 22 fixedly connected to the support column 21 drive the rotating chassis 15 to rotate synchronously. At this time, the nozzle 4 on the rotating chassis 15 also starts to rotate synchronously, and the nozzle 4 in contact with the welding head of the flange automatic welding robot will be continuously threaded with the welding head of the flange automatic welding robot due to rotation, and finally installed on the welding head of the flange automatic welding robot, so as to achieve the purpose of automatically installing the nozzle 4, making the process of installing the nozzle 4 convenient.

[0047] In the second step, when the nozzle 4 needs to be replaced, the old nozzle on the welding head is aligned with a rotating chassis 15 without a nozzle 4, and the motor 2 23 is controlled to output in reverse. At this time, since the limit blocks 17 at both ends of the old nozzle are supported by four limit rods 16, the rotating chassis 15 drives the old nozzle to rotate in the opposite direction, so that the old nozzle is directly separated from the welding head of the flange automatic welding robot. At this time, the motor 17 is started, and the motor 17 drives the meshing threaded rod 12 to rotate, and the meshing gear 13 will rotate synchronously with the meshing threaded rod 12. At this time, the meshing gear 13 drives the rotating disk 6 to rotate through the fixed frame 18. When the new nozzle of the rotating chassis 15 is aligned with the welding head of the flange automatic welding robot, the motor 2 23 is restarted, so that the new nozzle is re-threaded on the welding head of the flange automatic welding robot, so as to achieve the purpose of automatically replacing the nozzle 4, so that no cooling and waiting are required during the replacement process, thereby avoiding increasing the downtime of the production line, affecting the continuity of welding, and improving production efficiency.

[0048] The third step, when welding is to be carried out, start the motor three 31, at this time, the long rod 30 and the two rotating gears 33 driven by the motor three 31 rotate, because the two gear bars 39 on the lifting frame 34 are meshed with the rotating gear 33, therefore, when the rotating gear 33 rotates, the lifting frame 34 will drive the glass baffle 35 to rise, until it rises to a suitable distance, and then turn off the motor three 31. At this time, the glass baffle 35 will not affect the visual sensor of the flange automatic welding robot, but will also block the sparks flying during welding, avoiding the metal particles from adhering to the rotating mechanism to form bulges, reducing the surface smoothness of the rotating mechanism, affecting the rotation flexibility and stability of the rotating parts, so that the rotating shaft 2 can rotate stably, the fixed frame three 32 is stably fixed on the base 3, and the motor three 31 is fixedly connected to the fixed frame three 32. When the device body 1 is welding, it drives the base 3 to vibrate. The motor three 31 is stable It is fixed on the fixed frame three 32, so the motor three 31 will not be positionally shifted. The fixed frame three 32 provides a stable output environment for the output of the motor three 31, and provides stability for the motor three 31 during output. The support block 20 is rotatably connected to the connecting rod 26, so that the meshing bevel gears 27 at both ends of the connecting rod 26 have a more stable transmission effect when meshing and transmitting the rotating bevel gear 22, avoiding the meshing bevel gear 27 from having poor meshing, tooth jumping, sliding, or intermittent transmission during transmission, and improving the meshing transmission effect between the bevel gears. When the motor three 31 drives the lifting frame 34 and the glass baffle 35 to rise, at this time, the two limit columns 2 38 are both inside the lifting frame 34, and the lifting frame 34 can only move along the limit columns 2 38 during lifting, making the lifting frame 34 more stable when rising, avoiding the lifting frame 34 from having positional shift when rising, and improving the stability of the lifting frame 34 when rising.
