Description

Technical Field

[0001] This utility model relates to the field of cable iron and wood reel processing technology, specifically a welding machine for cable iron and wood reels. Background Technology

[0002] Cable reels, simply put, are large, reusable spools or reels used for winding, transporting, storing, and protecting power or communication cables. The core component is a sturdy steel cylinder on which the cable is wound. Side plates / baffles are typically two circular steel flanges located on either side of the reel to restrain the cable and prevent it from scattering. Forklift holes are usually present along the edges of the side plates for easy handling. Reinforcing ribs welded to the side plates significantly enhance the structural strength of the entire reel, enabling it to withstand weights of several tons or even tens of tons. (The text also mentions protective plates, but these are not directly related to the cable reel description.) The outer surface of the steel drum is covered with a wooden protective plate, mainly to protect the outer sheath of the cable. If the cable is directly wound on the rough steel drum, the sharp steel edges may cut or wear the cable insulation layer and outer sheath during transportation or winding and unwinding, causing safety hazards. A welding machine for cable iron and wood reels is a special welding equipment for manufacturing and repairing steel skeletons of cable iron and wood reels. It is usually not a single machine, but a workstation or production line that integrates multiple welding functions and auxiliary equipment. The existing cable reel welding machine places the cable reel on the upper part of the machine platform when welding it. Then, compressed air is output from the air compressor and enters the rodless chamber of multiple cylinders, pushing the cylinder rod to extend. The cylinder rod drives the clamping plate to move closer to and clamp the cable reel, thus clamping the cable reel. Then, the welding robot arm welds the cable reel. Existing cable reel welding machines have the following problems: when welding cable reels, the reels are clamped pneumatically, and air pressure fluctuations can easily lead to unstable clamping force, causing the cable reels to shift, which will affect the welding quality. Therefore, we propose a cable reel welding machine. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a welding machine for cable iron and wood reels. When welding cable iron and wood reels, the mechanical structure clamps the cable iron and wood reels, making the clamping force more stable, avoiding the cable iron and wood reels from shifting, and improving the welding quality of the cable iron and wood reels. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a welding machine for cable iron and wood reels, including a support, a welding mechanical arm provided on the top wall of the support, a base provided at the lower end of the support, a rotating table rotatably connected inside the base, an annular baffle provided inside the rotating table, and a clamping mechanism. Clamping mechanism: It includes support rods, clamping plates, threaded rods, internal threaded discs, U-shaped blocks, connecting rods, and U-shaped seats.

Clamping plates are fixedly connected between the ends of two adjacent support rods furthest from the center of the base. Threaded rods are rotatably connected between the upper and lower inner walls of the rotating platform. The upper end of the threaded rod is threadedly connected to an internal threaded disc. U-shaped blocks are evenly distributed on the outer surface of the internal threaded disc. U-shaped seats are fixedly connected between the ends of two adjacent support rods closest to the center of the base. Connecting rods are rotatably connected between the U-shaped blocks and adjacent U-shaped seats via pins. When welding cable reels, the mechanical structure clamps the cable reels, resulting in more stable clamping force, preventing displacement of the cable reels, and improving the welding quality of the cable reels.

[0005] Furthermore, a microcontroller is mounted on the outer surface of the bracket, a slip ring is fixedly connected to the lower end of the rotary table, a conductive rod is mounted on the bottom wall of the base, the input end of the microcontroller is electrically connected to an external power source, and the input ends of the welding robotic arm and the conductive rod are both electrically connected to the output end of the microcontroller, providing electrical connections for various electrical components.

[0006] Furthermore, the clamping mechanism also includes a drive assembly, which includes a protective cover, a worm gear, and a worm wheel. The protective cover is disposed on the bottom wall of the rotary table, and a worm gear is rotatably connected between the front and rear inner walls of the protective cover. A worm wheel is fixedly sleeved on the outer surface of the lower end of the threaded rod, and the worm gear and the worm wheel are meshed and connected to provide a transmission connection.

[0007] Furthermore, the drive assembly also includes a motor, which is located at the front end of the protective cover. The rear end of the motor's output shaft is fixedly connected to the front end of the worm gear, and the input end of the motor is electrically connected to the output end of the slip ring to provide rotational drive.

[0008] Furthermore, the drive assembly also includes an angle sensor, which is located at the rear end of the protective cover.

The angle sensor is bidirectionally electrically connected to the microcontroller to provide angle monitoring.

[0009] Furthermore, a gear ring is fixedly fitted on the outer surface of the rotary table, and a protective box is provided on the outer surface of the base. A gear is rotatably connected between the upper and lower inner walls of the protective box through a rotating column. The gear ring meshes with the gear to provide a transmission connection.

[0010] Furthermore, a right-angle motor is provided at the upper end of the protective box. The lower end of the output shaft of the right-angle motor is fixedly connected to the upper end of the rotating column. The input end of the right-angle motor is electrically connected to the output end of the microcontroller to provide rotation drive.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This welding machine for cable iron and wood reels has the following advantages: Driven by the motor, the worm gear and meshing worm wheel cause the threaded rod to move the internal threaded disc up and down. When the internal threaded disc moves upward, the connecting rod pushes the support rod to open outward, and the clamping plate releases the cable reel. When the internal threaded disc moves downward, the connecting rod pulls the support rod to retract inward, and the clamping plate clamps the cable reel. During welding of the cable reel, the mechanical structure clamps the cable reel, resulting in a more stable clamping force, preventing the cable reel from shifting, and improving the welding quality of the cable reel.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4This embodiment provides a technical solution: a welding machine for cable reels made of iron and wood, including a support 1, with a welding robotic arm 2 mounted on the top wall of the support 1. (The welding robotic arm 2 is a conventional six-axis welding robotic arm, which includes six axes (J1, J2, J3, J4, J5, and J6), an end effector (welding head), a sensing system, and a control system. The J1 axis rotates the base to achieve left and right rotation of the robot as a whole; the J2 axis tilts the lower arm to control the forward and backward swing of the upper arm; the J3 axis tilts the upper arm to control the forward and backward swing of the lower arm; the J4 axis rotates the wrist to control the rotation of the end flange; the J5 axis swings the wrist to control the up and down nodding of the end tool; and the J6 axis rotates the wrist to control the rotation of the end tool around its center line.) The combined motion of the axes enables the robot to reach any point within its workspace. The sensing system provides tactile feedback, while the vision system uses a 2D or 3D camera for coarse positioning, identifying the workpiece's position and orientation, compensating for placement errors, defect detection, identifying welding points, scanning the workpiece surface, and automatically generating welding paths. The welding head will weld the cable / wood reel. A rubber protective cloth can be fitted over the welding robot arm 2 to protect it and prevent welding sparks from entering its interior through the joints, thus avoiding damage to its precision components. The lower end of the support 1 has a base 4, and a rotating platform 5 is rotatably connected inside the base 4. The rotating platform 5 has an annular baffle 6 inside. The system includes a clamping mechanism 7, a microcontroller 3 mounted on the outer surface of the support 1, a slip ring 12 fixedly connected to the lower end of the rotary table 5, a conductive rod 13 mounted on the bottom wall of the base 4, an input terminal of the microcontroller 3 electrically connected to an external power source, and input terminals of the welding robotic arm 2 and the conductive rod 13 electrically connected to the output terminal of the microcontroller 3. A gear ring 8 is fixedly fitted onto the outer surface of the rotary table 5, and a protective box 10 is mounted on the outer surface of the base 4. A gear 9 is rotatably connected between the upper and lower inner walls of the protective box 10 via a rotating column, with the gear ring 8 meshing with the gear 9. A right-angle motor 11 is mounted on the upper end of the protective box 10, with the lower end of the output shaft of the right-angle motor 11 fixedly connected to the upper end of the rotating column. The input terminal of the right-angle motor 11 is electrically connected to the output terminal of the microcontroller 3. The system will then be controlled by the microcontroller 3 to... Motor 11 operates, and the output shaft of the right-angle motor 11 drives gear 9 to rotate. Gear 9 meshes with gear ring 8, thereby driving the rotary table 5 to rotate around the central axis within the base 4. The collector ring 12 at the lower end of the rotary table 5 contacts the conductive rod 13 on the bottom wall of the base 4, forming a sliding conductive structure. This structure ensures that when the rotary table 5 rotates, the microcontroller 3 can supply power to the motor 784 on the rotary table through the path of the conductive rod 13 and the collector ring 12, and also ensures that the signal from the angle sensor 785 is stably transmitted to the microcontroller 3, avoiding wire tangling. The rotation of the rotary table 5 will drive the cable reel to rotate, and then, under the control of the microcontroller 3, the welding robotic arm 2 will operate. The welding robotic arm 2 performs welding operations on the cable reel on the rotary table 5 according to a preset program.The rotation of the rotary table 5 enables the welding robotic arm 2 to continuously weld the weld seam in the circumferential direction of the cable reel; Clamping mechanism 7 includes a support rod 71, a clamping plate 72, a threaded rod 73, an internal threaded disc 74, a U-shaped block 75, a connecting rod 76, and a U-shaped seat 77. Evenly distributed sliding holes, arranged in pairs, are provided between the rotary table 5 and the annular baffle 6. Support rods 71 ​​are slidably connected inside each sliding hole. A clamping plate 72 is fixedly connected between the ends of two adjacent support rods 71 ​​furthest from the center of the base 4. Threaded rods 73 are rotatably connected between the upper and lower inner walls of the rotary table 5. (Corrugated pipes can be fixedly connected between the top wall of the rotary table 5 and the upper end of the internal threaded disc 74, and between the lower end of the internal threaded disc 74 and the upper end of the protective cover 781. The corrugated pipes will be sleeved on the outside of the threaded rods 73, protecting them from debris and dust entering their interior, and ensuring the sealing and lubrication of the threaded rods 73.)The upper end of the threaded rod 73 is threadedly connected to an internal threaded disc 74. The outer surface of the internal threaded disc 74 is provided with evenly distributed U-shaped blocks 75. U-shaped seats 77 are fixedly connected between the ends of two adjacent support rods 71 ​​near the center of the base 4. The U-shaped blocks 75 and the adjacent U-shaped seats 77 are rotatably connected by connecting rods 76 via pins. The clamping mechanism 7 also includes a drive assembly 78, which includes a protective cover 781, a worm gear 782, and a worm wheel 783. The protective cover 781 is disposed on the bottom wall of the rotary table 5. The worm gear 782 is rotatably connected between the front and rear inner walls of the protective cover 781. The worm wheel 783 is fixedly sleeved on the outer surface of the lower end of the threaded rod 73. The worm gear 782 and the worm wheel 783 are connected by a worm wheel 783. The worm gear 783 is engaged with the drive assembly 78, which also includes a motor 784. The motor 784 is located at the front end of the protective cover 781. The rear end of the output shaft of the motor 784 is fixedly connected to the front end of the worm 782. The input end of the motor 784 is electrically connected to the output end of the slip ring 12. The drive assembly 78 also includes an angle sensor 785, which is located at the rear end of the protective cover 781. The middle part of the counting shaft of the angle sensor 785 is fixedly connected to the rear end of the worm 782. The angle sensor 785 is bidirectionally electrically connected to the microcontroller 3. When welding the cable reel, the cable reel is first placed on the top of the rotary table 5. Then, the motor is controlled by the microcontroller 3. 784 operates, and the output shaft of motor 784 drives worm gear 782 to rotate. Worm gear 782 meshes with worm wheel 783, thereby driving threaded rod 73 to rotate within rotary table 5. When threaded rod 73 rotates, internal threaded disc 74, which is threaded with threaded rod 73, moves up and down along threaded rod 73. U-shaped block 75 on internal threaded disc 74 pulls or pushes U-shaped seat 77 on support rod 71 through connecting rod 76, causing support rod 71 to slide along the sliding hole between rotary table 5 and annular baffle 6. When internal threaded disc moves upward, connecting rod 76 pushes support rod 71 to open outward, and clamping plate 72 releases cable tray. When internal threaded disc 74 moves downward, connecting rod 76 pulls support rod 71 to open outward. 1. The clamping plate 72 clamps the cable reel inwards. The angle sensor 785 monitors the worm gear 782 in real time and transmits the signal to the microcontroller 3. The microcontroller 3 integrates the information (when the worm gear 782 rotates three times, it will drive the worm wheel 783 to rotate one revolution. The worm wheel 783 will drive the threaded rod 73 to rotate one revolution. The threaded rod 73 will drive the internal threaded disc 74 to move up or down by 5cm, which will then pull the clamping plate 72 at the upper end of the support rod 71 outwards or inwards by 2.5cm through the U-shaped block 75, connecting rod 76, and U-shaped seat 77). The microcontroller 3 determines whether the clamping plate has reached the appropriate clamping degree and controls the motor 784 to start and stop, avoiding over-clamping or unstable clamping.

[0016] The working principle of the cable reel welding machine provided by this utility model is as follows: When welding the cable reel, the cable reel is first placed on the upper end of the rotary table 5. Then, through the control of the microcontroller 3, the motor 784 operates. The output shaft of the motor 784 drives the worm gear 782 to rotate. The worm gear 782 meshes with the worm wheel 783, thereby driving the threaded rod 73 to rotate within the rotary table 5. When the threaded rod 73 rotates, the internal threaded disc 74, which is threaded with the threaded rod 73, moves up and down along the threaded rod 73. The U-shaped block 75 pulls or pushes the U-shaped seat 77 on the support rod 71 via the connecting rod 76, causing the support rod 71 to slide along the sliding hole between the rotary table 5 and the annular baffle 6. When the internal threaded disc moves upward, the connecting rod 76 pushes the support rod 71 to open outward, and the clamping plate 72 releases the cable reel. When the internal threaded disc 74 moves downward, the connecting rod 76 pulls the support rod 71 to retract inward, and the clamping plate 72 clamps the cable reel. The angle sensor 785 will detect the worm gear 782 in real time and transmit the signal to the microcontroller 3. The microcontroller 3 integrates the information, determines whether the clamping plate has reached the appropriate clamping degree, and then controls the motor 784 to start and stop, avoiding over-clamping or unstable clamping. Next, through the control of the microcontroller 3, the right-angle motor 11 operates. The output shaft of the right-angle motor 11 drives the gear 9 to rotate. The gear 9 meshes with the gear ring 8, thereby driving the rotary table 5 to rotate around the central axis within the base 4. The collector ring 12 at the lower end of the rotary table 5 contacts the conductive rod 13 on the bottom wall of the base 4, forming a sliding conductive structure. This structure ensures that the microcontroller... The 3 can supply power to the motor 784 on the rotary table through the path of the conductive rod 13 and the collector ring 12, and can also stably transmit the signal of the angle sensor 785 to the microcontroller 3, avoiding wire tangling. The rotation of the rotary table 5 will drive the cable iron and wood reel to rotate, and then the welding robot arm 2 will operate under the control of the microcontroller 3. The welding robot arm 2 will perform welding operations on the cable iron and wood reel on the rotary table 5 according to the preset program. At the same time, the rotation of the rotary table 5 allows the welding robot arm 2 to continuously weld the weld seam in the circumferential direction of the cable iron and wood reel.

[0017] It is worth noting that the welding robotic arm 2, motor 784, angle sensor 785, and right-angle motor 11 disclosed in the above embodiments can be selected as follows: welding robotic arm 2 can be ER6-1400, motor 784 can be YS8024, angle sensor 785 can be E6B2-CWZ6C, and right-angle motor 11 can be 5IK60RGN-C. The microcontroller 3 controls the operation of welding robotic arm 2, motor 784, angle sensor 785, and right-angle motor 11 using methods commonly used in the prior art.
