Description

Technical Field

[0001] This invention relates to the field of horizontal rotary table assembly welding technology, and more particularly to a horizontal rotary table assembly welding device. Background Technology

[0002] Welding is a manufacturing process that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Horizontal turntable combined welding equipment is a type of welding equipment.

[0003] In existing horizontal rotary table welding devices, when welding objects, the welding torch is moved above the welding point by a linear adjustment component, and then the position of the welding torch is adjusted by a robotic arm at the outer end of the welding torch. This adjustment method is relatively monotonous. If the object is complex in shape and the welding position is inside multiple structures, simply using the robotic arm to move the welding torch 360° cannot achieve precise alignment between the welding torch and the welding point of the object. This will result in poor welding effect and reduce the use value of the horizontal rotary table welding device. Summary of the Invention

[0004] This invention discloses a horizontal rotary table combined welding device, aiming to solve the problem that in the existing horizontal rotary table combined welding devices, when welding objects, the welding torch is moved above the welding point by a linear adjustment component, and then the position of the welding torch is adjusted by a robotic arm at the outer end of the welding torch. This adjustment method is relatively monotonous. If dealing with some objects with complex shapes, where the required welding position is inside multiple structures, simply using the robotic arm to move the welding torch 360° cannot achieve precise docking between the welding torch and the welding point of the object, which will lead to poor welding results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A horizontal rotary table combined welding device includes an operating platform and a lifting plate. The lifting plate is provided with a preliminary adjustment component, which includes a semi-circular ring rod and an annular limiting rail. The semi-circular ring rod is fixedly connected to the top of the lifting plate. A groove is formed at the bottom of the lifting plate. The inner walls of both sides of the groove are connected to the same rotating shaft through bearings. A deflection rod is fixedly connected to the outer side of the rotating shaft. The other end of the deflection rod has a groove. A linkage rod is slidably connected inside the groove. A U-shaped rod is fixedly connected to the other end of the linkage rod. A connecting rod is fixedly connected to the outer side of the semi-circular ring rod, and the annular limiting rail is fixedly connected to the outer side of the connecting rod. An extension frame is fixedly connected to the outer side of the U-shaped rod. A sliding block is fixedly connected to the other end of the U-shaped rod, and the sliding block is slidably connected to the annular limiting rail. Inside the positioning rail, a mounting block is fixedly connected to the inner side of the semi-circular ring rod, and a hydraulic cylinder is hinged to the outer side of the mounting block facing the deflection rod. The output end of the hydraulic cylinder is hinged to the outer side of the deflection rod. A mechanical control arm is fixedly connected to the outer side of the extension frame, and a fixing ring is fixedly connected to the operating end of the mechanical control arm. A welding torch is fixedly connected inside the fixing ring. A dial is fixedly connected to the outer side of the annular limiting rail facing the extension frame, and a motor plate is fixedly connected to the annular limiting rail. A forward and reverse motor is fixedly connected to the side of the motor plate facing the extension frame. The output shaft of the forward and reverse motor is fixedly connected to a drive shaft through a coupling. A connecting rod is fixedly connected to the outer side of the drive shaft, and the connecting rod is slidably connected inside the annular limiting rail.

[0007] By incorporating an initial adjustment component, after the object is fixed before welding, the angle of the welding torch is adjusted according to the angle of the object's welding position. The forward and reverse motors are then activated, causing the connecting rod to slide within the annular limit rail. This slides the connecting rod to the corresponding angle, which is then checked against a scale. The connecting rod then limits the sliding block for subsequent adjustments. Next, the hydraulic cylinder one raises the deflection rod, which in turn pushes the linkage rod towards the annular limit rail. This causes the sliding block below the U-shaped rod to slide within the annular limit rail. When the sliding block contacts the connecting rod, the initial angle adjustment of the welding torch is complete, ensuring that the welding torch and the object's welding position are in a straight line on the same plane, with no obstructions between them. This facilitates the mechanical control arm two to move the welding torch linearly to the welding point. The combined action of the initial adjustment component and the mechanical control arm two ensures precise alignment between the welding torch and the welding point, improving the welding effect and thus enhancing the usability of the welding device.

[0008] In a preferred embodiment, a placement frame is fixedly connected to the top of the operating table, and a first track is fixedly connected to the bottom inner wall of the placement frame. A second track is slidably connected to the first track, and a moving block is slidably connected inside the second track. A mounting column is connected to the top of the moving block via a bearing, and a height plate is fixedly connected to the top of the mounting column.

[0009] In a preferred embodiment, a lifting groove is provided on one side of the height plate, and the same lifting rod is connected between the top inner wall and the bottom inner wall of the lifting groove via a bearing. A lifting block is slidably connected to the outside of the lifting rod, and a lifting plate is fixedly connected to the outside of the lifting block. A support plate is fixedly connected to the side of the height plate near the bottom end, and a hydraulic cylinder is fixedly connected to the top of the support plate. The output end of the hydraulic cylinder is fixedly connected to the bottom of the lifting block.

[0010] In a preferred embodiment, a second drive motor is fixedly connected to the top of the movable block, and the output shaft of the second drive motor is fixedly connected to a drive shaft via a coupling. A drive gear is fixedly connected to the outside of the drive shaft. A placement groove is opened on the outside of the mounting column, and a driven gear is connected to the inside of the placement groove via a bearing. The drive gear and the driven gear mesh with each other.

[0011] In a preferred embodiment, the top two ends of the operating table are provided with clamping and supporting assemblies, and the clamping and supporting assemblies include two fixed plates. Each of the two fixed plates has a shaft groove on its opposite side. The interior of each shaft groove is connected to a rotating shaft through a bearing. A drive motor is fixedly connected to the outer side of one of the fixed plates. The output shaft of the drive motor is connected to one of the rotating shafts through a coupling.

[0012] In a preferred embodiment, a rotating ring plate is fixedly connected to each of the two rotating shafts on opposite sides, and two hydraulic cylinders are fixedly connected to each of the two rotating ring plates on opposite sides. The output ends of the two hydraulic cylinders located on the same rotating ring plate are fixedly connected to the same clamping plate. A sleeve groove is opened on the outer side of each of the two rotating shafts, and a gravity tripod is sleeved inside the sleeve groove. An installation rod is fixedly connected to the outer side of the gravity tripod, and a cylinder is fixedly connected to the bottom of the installation rod. A bracket is fixedly connected to the output end of the cylinder, and an installation groove is opened on the bracket. Sliding contact rollers are connected at equal intervals to the inner wall of the installation groove via bearings.

[0013] By incorporating a clamping and supporting assembly, an object is clamped and placed between two clamping plates. Hydraulic cylinder two is adjusted to move the clamping plates to clamp both ends of the object. After clamping, an air cylinder is adjusted to move the support upwards, causing the bottom of the object to contact the sliding contact roller. If the object needs to be rotated during welding, drive motor one is activated, driving the rotating shaft to rotate. During the rotation, the gravity tripod slides inside the socket groove, ensuring the support remains below the object and in constant contact with it, thus ensuring the safety of the clamped object during rotation.

[0014] In a preferred embodiment, a heat-conducting component is provided on the outer side of another fixed plate, and the heat-conducting component includes a mechanical control arm and a heat-conducting cover. The mechanical control arm is fixedly connected to the outer side of the fixed plate, and the heat-conducting cover is fixedly connected to the operating end of the mechanical control arm.

[0015] In a preferred embodiment, the heat-conducting cover is provided with a heat-insulating sealing sleeve on the side facing the placement frame, and a gas guide ring pipe is fixedly connected inside the heat-conducting cover. The gas guide ring pipe has gas guide holes at equal intervals on the outer side of the center point of the gas guide cover, and a pump frame is fixedly connected to the outer side of the heat-conducting cover.

[0016] In a preferred embodiment, an air pump is fixedly connected to the pump frame, the air pump's suction end is connected to the inside of the air guide ring pipe through a pipe, and the air pump's delivery end is fixedly connected to an external long pipe.

[0017] By incorporating heat-conducting components, during welding operations, adjusting the mechanical control arm moves the heat-conducting cover to the outside of the welding point. This causes the heat-insulating sealing sleeve to come into contact with and compress the outside of the object, deforming the sleeve and improving the sealing effect. By sealing the outside of the welding point with the heat-conducting cover, the rapid loss of heat can be prevented, thus avoiding a reduction in welding efficiency. Simultaneously, it prevents excessively high ambient temperatures caused by heat loss. After welding is completed, the air pump is activated, directing the hot gas inside the heat-conducting cover through an external long pipe to other heat exchange components, thereby recovering heat and improving the safety performance of the welding device.

[0018] As can be seen from the above, the horizontal turntable combined welding device provided by the present invention can slide the connecting rod inside the annular limiting rail to a corresponding angle. By comparing with the scale, the connecting rod limits the sliding block of the subsequent adjustment. Then, the hydraulic cylinder one drives the deflection rod to rise, thereby driving the linkage rod to push towards the annular limiting rail, and driving the sliding block below the U-shaped rod to slide inside the annular limiting rail. When the sliding block contacts the connecting rod, the initial adjustment of the welding torch angle is completed, so that the welding torch and the welding position of the object are in a straight line on the same plane, with no object obstructing between them. This facilitates the mechanical control arm two to drive the welding torch to move linearly to the welding point. The initial adjustment component and the mechanical control arm two work together to ensure that the welding torch and the welding point are accurately aligned, thus improving the welding effect.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] The horizontal rotary table combined welding device disclosed in this invention is mainly applied to the existing horizontal rotary table combined welding device. When welding objects, the welding torch is moved above the welding point by the linear adjustment component, and then the position of the welding torch is adjusted by the robotic arm at the outer end of the welding torch. This adjustment method is relatively monotonous. If some objects with complex shapes are encountered, and the required welding position is inside multiple structures, simply using the robotic arm to drive the welding torch to adjust 360° cannot achieve precise docking between the welding torch and the welding point of the object. This will result in poor welding effect.

[0030] Reference Figures 1-8 The horizontal rotary table combined welding device of the present invention includes an operating table 1 and a lifting plate 5. The lifting plate 5 is provided with a preliminary adjustment component 6, which includes a semi-circular ring rod 601 and an annular limiting rail 613. The semi-circular ring rod 601 is fixedly connected to the top of the lifting plate 5. A groove is formed at the bottom of the lifting plate 5. The inner walls of both sides of the groove are connected to the same rotating shaft 603 via bearings. A deflection rod 608 is fixedly connected to the outer side of the rotating shaft 603. A groove is formed at the other end of the deflection rod 608. A linkage rod 609 is slidably connected inside the groove. A U-shaped rod 606 is fixedly connected to the other end of the linkage rod 609. A connecting rod 602 is fixedly connected to the outer side of the semi-circular ring rod 601, and the annular limiting rail 613 is fixedly connected to the outer side of the connecting rod 602. An extension frame 615 is fixedly connected to the outer side of the U-shaped rod 606. A sliding block 610 is fixedly connected to the other end of the U-shaped rod 606, and the sliding block 610 is slidably connected to the annular limiting rail 613. Inside 3, a mounting block 605 is fixedly connected to the inner side of the semi-circular ring rod 601, and a hydraulic cylinder 604 is hinged to the outer side of the mounting block 605 facing the deflection rod 608. The output end of the hydraulic cylinder 604 is hinged to the outer side of the deflection rod 608. A mechanical control arm 11 is fixedly connected to the outer side of the extension frame 615, and a fixing ring 12 is fixedly connected to the operating end of the mechanical control arm 11. A welding torch 8 is fixedly connected inside the fixing ring 12. A dial 616 is fixedly connected to the outer side of the annular limit rail 613 facing the extension frame 615, and a motor plate 614 is fixedly connected to the annular limit rail 613. A forward and reverse motor 612 is fixedly connected to the side of the motor plate 614 facing the extension frame 615. The output shaft of the forward and reverse motor 612 is fixedly connected to the drive shaft 611 through a coupling. A connecting rod 607 is fixedly connected to the outer side of the drive shaft 611, and the connecting rod 607 is slidably connected inside the annular limit rail 613.

[0031] In a specific application scenario, before welding with the welding torch 8, after fixing the object, the angle of the welding torch 8 is adjusted according to the angle of the object's welding position. The forward and reverse motor 612 is started, which drives the connecting rod 607 to slide inside the annular limit rail 613, thereby sliding the connecting rod 607 to the corresponding angle. The scale 616 is used for reference, and the connecting rod 607 limits the sliding block 610 for subsequent adjustment. Then, the hydraulic cylinder 604 is adjusted to drive the deflection rod 608 to rise, thereby driving the linkage rod 609 towards the annular limit rail. Pushing 613 causes the sliding block 610 below the U-shaped rod 606 to slide inside the annular limiting rail 613. When the sliding block 610 contacts the connecting rod 607, the initial angle adjustment of the welding torch 8 is completed, so that the welding torch 8 and the welding position of the object are in a straight line on the same plane, with no object obstructing between them. This facilitates the mechanical control arm 2 11 to drive the welding torch 8 to the welding point in a straight line. The initial adjustment component 6 and the mechanical control arm 2 11 work together to ensure that the welding torch 8 is precisely aligned with the welding point, improve the welding effect, and thus enhance the use value of the welding device.

[0032] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 In a preferred embodiment, a placement frame 2 is fixedly connected to the top of the operating table 1, and a first track 3 is fixedly connected to the bottom inner wall of the placement frame 2. A second track 10 is slidably connected to the first track 3. A moving block 17 is slidably connected inside the second track 10. A mounting column 18 is connected to the top of the moving block 17 via a bearing. A height plate 4 is fixedly connected to the top of the mounting column 18. A lifting groove is opened on one side of the height plate 4, and the same lifting rod 13 is connected between the top inner wall and the bottom inner wall of the lifting groove via a bearing. A lifting block 14 is slidably connected to the outside of the lifting rod 13. The lifting plate 5 is fixed. A support plate 16 is fixedly connected to the outside of the lifting block 14. A hydraulic cylinder 15 is fixedly connected to the top of the support plate 16. The output end of the hydraulic cylinder 15 is fixedly connected to the bottom of the lifting block 14.

A drive gear 21 is fixedly connected to the outside of the drive shaft 20. A placement groove is opened on the outside of the mounting column 18. A driven gear 19 is connected to the inside of the placement groove through a bearing. The drive gear 21 and the driven gear 19 mesh with each other.

[0033] Reference Figure 1 , Figure 2 and Figure 5In a preferred embodiment, the top two ends of the operating table 1 are provided with clamping and supporting assemblies 7, and the clamping and supporting assemblies 7 include two fixing plates 701. Each fixing plate 701 has a shaft groove on its opposite side, and a rotating shaft 702 is connected to the inside of each shaft groove via bearings. A drive motor 703 is fixedly connected to the outer side of one of the fixing plates 701. The output shaft of the drive motor 703 is connected to one of the rotating shafts 702 via a coupling. Rotating ring plates 707 are fixedly connected to the opposite sides of each of the two rotating shafts 702, and rotating ring plates 707 are fixedly connected to the opposite sides of each of the two rotating ring plates 707. Two hydraulic cylinders 704 are connected. The output ends of the two hydraulic cylinders 704, which are located on the same rotating ring plate 707, are fixedly connected to the same clamping plate 706. The outer sides of the two rotating shafts 702 are each opened with a sleeve groove 705. A gravity tripod 708 is sleeved inside the sleeve groove 705. An installation rod 712 is fixedly connected to the outer side of the gravity tripod 708. A cylinder 710 is fixedly connected to the bottom of the installation rod 712. A bracket 711 is fixedly connected to the output end of the cylinder 710. An installation groove is opened on the bracket 711. Sliding contact rollers 709 are connected at equal intervals through bearings on the inner wall of the installation groove.

[0034] It should be noted that when clamping the object, it is placed between two clamping plates 706. The hydraulic cylinder 704 is adjusted to drive the clamping plates 706 to clamp both ends of the object. After clamping, the cylinder 710 is adjusted to drive the bracket 711 to move upward, so that the bottom of the object contacts the sliding contact roller 709. If the object needs to be rotated during the welding process, the drive motor 703 is started. The drive motor 703 drives the rotating shaft 702 to rotate. During the rotation of the rotating shaft 702, the gravity tripod 708 slides inside the socket groove 705 to ensure that the bracket 711 is always below the object and can always be in contact with it, thereby ensuring the safety of the clamped object during the rotation process.

[0035] Reference Figure 1 , Figure 2 and Figure 6 In a preferred embodiment, a heat-conducting component 9 is provided on the outer side of another fixed plate 701. The heat-conducting component 9 includes a mechanical control arm 902 and a heat-conducting cover 901. The mechanical control arm 902 is fixedly connected to the outer side of the fixed plate 701, and the heat-conducting cover 901 is fixedly connected to the operating end of the mechanical control arm 902. A heat-insulating sealing sleeve 903 is provided on the side of the heat-conducting cover 901 facing the placement frame 2. A gas guide ring pipe 904 is fixedly connected inside the heat-conducting cover 901. Gas guide holes 905 are opened at equal intervals on the outer side of the center point of the gas guide cover facing the gas guide ring pipe 904. A pump frame 906 is fixedly connected to the outer side of the heat-conducting cover 901. An air pump 908 is fixedly connected to the pump frame 906. The air pump 908's suction end is connected to the inside of the gas guide ring pipe 904 through a pipe. The air pump 908's delivery end is fixedly connected to an external long pipe 907.

[0036] Specifically, during the welding operation, the mechanical control arm 902 moves the heat-conducting cover 901 to the outside of the welding point. The heat-insulating sealing sleeve 903 then contacts and presses against the outside of the object, causing it to deform. This improves the sealing effect between the heat-insulating sealing sleeve 903 and the object. By sealing the outside of the welding point with the heat-conducting cover 901, excessive heat loss is prevented, thus avoiding a reduction in welding efficiency. Simultaneously, heat loss is prevented from causing excessively high ambient temperatures. After welding is completed, the air pump 908 is activated. The air pump 908 guides the hot gas inside the heat-conducting cover 901 through the external long pipe 907 to other heat exchange components, thereby recovering heat and improving the safety performance of the welding device.

[0037] A welding method for a horizontal rotary table assembly welding device, using the horizontal rotary table assembly welding device as described above, includes the following steps:

[0038] Step 1: When clamping the object, place it between two clamping plates 706. Adjust the hydraulic cylinder 704 to drive the clamping plates 706 to clamp both ends of the object. After clamping, adjust the cylinder 710 to drive the bracket 711 to move upward, so that the bottom of the object contacts the sliding contact roller 709.

[0039] Step 2: Start the forward and reverse motor 612. The forward and reverse motor 612 drives the connecting rod 607 to slide inside the annular limit rail 613, thereby sliding the connecting rod 607 to the corresponding angle. Check the scale 616. The connecting rod 607 limits the sliding block 610 for subsequent adjustment. Then, adjust the hydraulic cylinder 604 to drive the deflection rod 608 to rise, thereby driving the linkage rod 609 to push towards the annular limit rail 613, causing the sliding block 610 below the U-shaped rod 606 to slide inside the annular limit rail 613. When the sliding block 610 contacts the connecting rod 607, the initial angle adjustment of the welding torch 8 is completed.

[0040] Step 3: Next, adjust the mechanical control arm 2 11 to drive the welding torch 8 to move linearly to the welding point. The welding torch 8 is precisely aligned with the welding point. Finally, adjust the mechanical control arm 1 902 to move the heat conduction cover 901 to the outside of the welding point. The heat insulation sealing sleeve 903 then comes into contact with and is squeezed against the outside of the object. The heat insulation sealing sleeve 903 deforms, and the contact and sealing effect between the heat insulation sealing sleeve 903 and the object is better. The outside of the welding point is sealed by the heat insulation sealing sleeve 903 and the heat conduction cover 901. After the sealing is completed, the welding operation on the object is started by the welding torch 8.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
