Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and in particular relates to a displacement welding platform for iron tower welding parts. Background Art

[0002] The Tower Welding Platform is a specialized welding auxiliary device designed for welding large, heavy, and complex-shaped components used in large steel structures such as power towers and communication towers. Its core function is to safely, efficiently, and precisely change the spatial position and posture of the workpiece, ensuring that the weld seam is always in the optimal position (usually a flat weld or a boat weld), significantly improving welding quality and efficiency.

[0003] The tower base is a key part of the tower structure. It is usually made of steel plates and is also the most common tower welding part. It is used to support the tower and ensure its stability. At present, the welding of the tower base is carried out by using a welding robot in conjunction with a position-shifting welding platform to automatically weld the pre-spot-welded base. Although the welding process has been automated, there are still some problems. Since the base is made of steel plates and is heavy, operators currently use a small crane to lift it and place it on the top of the welding platform. After welding is completed, the crane is also used to lift it off the platform. At the same time, after the tower base is hoisted on the top of the welding platform, it needs to be manually adjusted in position and locked with a positioning tool to ensure the stability and accuracy of subsequent welding. However, this operation method is not only time-consuming and labor-intensive, but also greatly affects the overall welding efficiency, which is not conducive to the continuous processing of large-scale products. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a displacement welding platform for tower welding parts.

[0005] The technical solution adopted to solve the above technical problems is: a displacement welding platform for iron tower welding parts, comprising a welding robot and a displacement adjustment mechanism arranged at adjacent positions, wherein a support mechanism for supporting and placing the iron tower base is fixedly installed on the top of the displacement adjustment mechanism;

[0006] An automatic positioning clamping mechanism for clamping the tower base is installed inside the support mechanism, and multiple sets of follow-up pre-adjustment mechanisms for adjusting the position of the tower base before clamping are fixedly installed on the automatic positioning clamping mechanism;

[0007] A rotating material changing platform is provided on one side of the displacement adjustment mechanism, which is used for alternate feeding and unloading of the tower base during the processing. An automatic lifting cantilever is also installed on the top of the rotating material changing platform near the front end;

[0008] The automatic lifting cantilever is rotatably connected to an electromagnetic suspension mechanism for magnetically fixing the tower base and cooperating with the automatic lifting cantilever to complete automatic loading and unloading of the tower base between the support mechanism and the rotating material changing platform.

[0009] Furthermore, the displacement adjustment mechanism includes a fixed frame, which is rotatably connected to a rotating seat. A first servo motor for driving the rotating seat to rotate is installed at one end of the fixed frame, and a second servo motor is also installed at the bottom of the rotating seat. The top of the output shaft of the second servo motor is fixedly connected to a rotating disk.

[0010] Through the above technical solution, the displacement adjustment mechanism is mainly used to adjust the position and angle of the tower base during the welding process. During specific operation, the first servo motor can drive the rotating seat to freely adjust various angles in the X-axis direction. At the same time, the second servo motor can also drive the rotating disk to freely adjust various angles in the Y-axis or Z-axis direction. In conjunction with the welding path programming of the welding robot, automatic welding can be performed according to the set welding program without the need for human intervention throughout the process. It should also be noted that the welding robot belongs to the existing mature technology, and its specific programming principle and working principle will not be described in detail here.

[0011] Furthermore, the support mechanism includes a fixed plate fixedly installed on the top of the displacement adjustment mechanism, a plurality of support blocks are fixedly connected to the periphery of the top of the fixed plate, a support platform is fixedly installed on the top of the plurality of support blocks, and a plurality of rectangular grooves are opened on the periphery of the support platform.

[0012] Through the above technical solution, the support mechanism mainly serves as a supporting structure, and the support platform on its top is used to place the tower base. At the same time, the automatic positioning and clamping mechanism also relies on it as an installation structure. During welding processing, the automatic positioning and clamping mechanism can firmly fix the tower base on the support platform, thereby cooperating with the displacement adjustment mechanism and the welding robot to quickly complete the welding work.

[0013] Furthermore, the automatic positioning clamping mechanism includes multiple groups of bearing seats fixedly installed on the circumferential side of the bottom of the support platform, each group of bearing seats is rotatably connected with a ball screw, a ball nut seat is installed on the ball screw, and the top of the ball nut seat is fixedly connected to a positioning clamp seat for fixing the corners of the tower base, and the inner end of each ball screw is fixedly installed with a transmission bevel gear, and a third servo motor is fixedly installed at the top center of the fixed plate, and the top of the output shaft of the third servo motor is fixedly connected to a driving bevel gear meshing with multiple transmission bevel gears.

[0014] Through the above technical scheme, the automatic positioning clamping mechanism is mainly used for the rapid clamping and fixing of the tower base, and ensures the stability of the tower base during the welding process, and does not deviate or shake. In specific operation, after the tower base is placed on the top of the support platform, the third servo motor starts to work, and drives the driving bevel gear to rotate through its output shaft. When the driving bevel gear rotates, it will synchronously drive multiple transmission bevel gears to rotate, and then the corresponding ball nut seats can be driven to move synchronously through the ball screw fixed thereto. During the synchronous movement, the multiple ball nut seats can drive the corresponding positioning clamp seats to clamp toward the center of the support platform or spread to its outside. During the clamping process, the position of the tower base is pre-adjusted in conjunction with multiple sets of follow-up pre-adjustment mechanisms, so that the multiple positioning clamp seats can be used to quickly fix the corners of the tower base, so that the tower base can be stably fixed on the support platform.

[0015] Furthermore, each group of the bearing seats is located directly below the corresponding rectangular groove, and the multiple ball nut seats are respectively slidably limited in the corresponding rectangular groove.

[0016] Through the above technical solution, under the limiting action of the rectangular groove and the bearing seat, the corresponding ball nut seat and positioning clamp seat can be moved along the fixed track, thereby ensuring the overall clamping accuracy and clamping efficiency.

[0017] Furthermore, the follow-up pre-adjustment mechanism includes a connecting seat fixed to the outside of the positioning clamp seat, and a connecting slot matching the positioning clamp seat is provided on the inner side of the connecting seat. Circular holes are provided at both ends of the connecting seat, and fixing rods are slidably connected in the two circular holes. One end of the fixing rod close to the tower base is fixedly connected to the positioning clamp block, and the other end is threadedly connected to a fixing nut. The outer wall of the fixing rod close to the positioning clamp block is also sleeved with a spring ring.

[0018] Through the above technical solution, the follow-up pre-adjustment mechanism is mainly used for pre-adjusting the clamping position of the tower base. When the tower base is automatically hoisted by the electromagnetic suspension mechanism and placed on the top of the supporting platform, there will be a small deviation in its actual position and angle. Therefore, during the process of clamping and fixing the tower base, the automatic positioning clamping mechanism, the fixing rod and the positioning clamp slidably installed on the connecting seat, under the elastic thrust of the spring coil, the positioning clamp will contact the tower base. As the positioning clamp seat continues to approach, the positioning clamp contacting the tower base will further squeeze the spring coil. During the continuous squeezing process, the spring coil pushes in the opposite direction. The force will also act on the positioning clamps, thereby pushing the tower base to move in the process. With the simultaneous push of multiple sets of positioning clamps from multiple directions, the position of the tower base can be adjusted to a suitable state, so that multiple positioning clamps can be accurately locked with the corresponding corners of the tower base in the subsequent process. It should be noted that the follow-up pre-adjustment mechanism can not only play a pre-adjustment positioning role, but also after the tower base is clamped and fixed, under the reverse thrust of multiple spring coils, it can also play an auxiliary fixing and limiting role on the bottom of the tower base, thereby ensuring the stability of the tower base during the welding process.

[0019] Furthermore, the rotating material changing platform includes a supporting base, on which a gear rotating platform and a driving gear are rotatably connected respectively. A fourth servo motor for driving the driving gear to rotate is installed on the top of the supporting base. The top of the gear rotating platform is also provided with a plurality of positioning angle seats for assisting in positioning the position of the tower base.

[0020] Through the above technical solution, the rotating material changing platform is mainly used for auxiliary replacement of the tower base during the loading and unloading process. During specific operation, the fourth servo motor can drive the gear rotating platform engaged with it to rotate through the driving gear, so as to realize the adjustment of the position of the tower base on the gear rotating platform, thereby forming a compact material supply and unloading system. In addition, there are multiple positioning angle seats on the top of the gear rotating platform. During the loading process, it is only necessary to fit one corner of the tower base with the slot of the positioning angle seat at a fixed angle to achieve precise positioning of the tower base, which can facilitate subsequent precise lifting.

[0021] Furthermore, the upper portion of the gear rotating platform is a disc structure, the lower circumference is a tooth groove structure, and the gear rotating platform and the driving gear are meshed with each other.

[0022] Furthermore, the automatic lifting cantilever includes a first rotating bracket and a second rotating bracket fixed on the top of the rotating material changing platform, the first rotating bracket is rotatably connected to the rotating arm, the top of the rear end of the rotating arm is fixedly connected to the main cantilever, and a positioning ring is installed at the rear end of the main cantilever, the second rotating bracket is rotatably connected to the first hydraulic cylinder, and the rotating arm is also fixedly connected to the third rotating bracket, and the end of the piston rod of the first hydraulic cylinder is rotatably connected to the third rotating bracket.

[0023] Through the above technical solution, when the automatic lifting cantilever is working, the first hydraulic cylinder can drive the rotating arm to rotate with the first rotating bracket as the fulcrum through the extension and contraction of the piston rod. During the rotation process, it can drive the electromagnetic suspension mechanism on the main cantilever to rotate synchronously, and then drive the iron tower base adsorbed and fixed on the electromagnetic suspension mechanism to reciprocate between the support mechanism and the rotating material changing platform for loading and unloading.

[0024] Furthermore, the electromagnetic suspension mechanism includes a suspension seat rotatably connected to the main cantilever, a second hydraulic cylinder is fixedly installed on the bottom of the suspension seat, the bottom end of the piston rod of the second hydraulic cylinder is fixedly connected to a mounting body, two adjacent surfaces of the mounting body are installed with electromagnetic suction components, and a wiring component for connecting the conductive wires of the two electromagnetic suction components is installed inside the mounting body.

[0025] Through the above technical solution, since the base of the iron tower is heavy and the upper structure is equally complex, and it is not conducive to clamping with a simple mechanical structure, a mounting body and an electromagnetic suction component are designed. The shape of the mounting body can be designed according to the shape of the upper structure of the iron tower base. It is only necessary to make the electromagnetic suction components on the two adjacent sides fit with the upper structure of the iron tower base. During the loading process, the automatic lifting cantilever first drives the entire electromagnetic suction suspension mechanism to rotate to the appropriate position above the iron tower base, and then the piston rod of the second hydraulic cylinder will drive the mounting body to move downward. When the mounting body drops to the specified height After the degree is reached, the wiring assembly is powered on, and the two electromagnetic suction assemblies will instantly generate strong magnetic attraction, so that the tower base can be firmly adsorbed and fixed. After the fixation is completed, the piston rod of the second hydraulic cylinder contracts and resets. At this time, it is lifted and hoisted to the top of the support platform by the automatic lifting cantilever, and then the piston rod of the second hydraulic cylinder extends downward until the bottom surface of the tower base fits with the upper surface of the support platform. At this time, the wiring assembly is powered off, and the two electromagnetic suction assemblies stop working and separate from the tower base, thereby completing the automatic lifting and loading process. The unloading process is the opposite of the above process and will not be described in detail here.

[0026] The beneficial effects of the present invention are as follows: (1) The present invention can replace manual labor to complete the automatic loading and unloading operations of welded parts by designing a rotating material changing platform, an automatic lifting cantilever and an electromagnetic suction suspension mechanism, which not only saves time and labor, but also reduces the safety hazards in the manual lifting process, and greatly improves work efficiency; (2) The present invention designs an automated welding platform, which does not require manual intervention, not only improves the overall welding efficiency, but also facilitates the continuous processing of large-scale products; (3) The present invention designs an automatic positioning clamping mechanism and a follow-up pre-adjustment mechanism, so that the welding platform can automatically complete the positioning and calibration of the welded parts and stable clamping and fixing, which not only saves manpower and material resources, but also ensures the subsequent welding accuracy and welding quality.

[0055] For automatic lifting boom 7, refer to Figure 14-16 , an automatic lifting cantilever 7 is also installed on the top of the rotating material changing platform 6 near the front end; the automatic lifting cantilever 7 includes a first rotating bracket 701 and a second rotating bracket 705 fixed to the top of the rotating material changing platform 6, a rotating arm 702 is rotatably connected to the first rotating bracket 701, a main cantilever 703 is fixedly connected to the top of the rear end of the rotating arm 702, a positioning ring 704 is installed at the rear end of the main cantilever 703, a first hydraulic cylinder 706 is rotatably connected to the second rotating bracket 705, and a third rotating bracket is also fixedly connected to the rotating arm 702.

A wiring component 805 for connecting the conductive wires of the two electromagnetic suction components 804 is installed inside the mounting body 803. Since the tower base 9 is heavy and the upper structure is complex, and it is not conducive to clamping with a simple mechanical structure, the mounting body 803 and the electromagnetic suction component 804 are designed. The shape of the mounting body 803 can be designed according to the shape of the upper structure of the tower base 9. It is only necessary to make the electromagnetic suction components 800 on the two adjacent surfaces 4 can fit with the upper structure of the tower base 9. During the loading process, the automatic lifting cantilever 7 first drives the entire electromagnetic suspension mechanism 8 to rotate to a suitable position above the tower base 9, and then the piston rod of the second hydraulic cylinder 802 drives the installation body 803 to move downward. When the installation body 803 drops to the specified height, the wiring assembly 805 is energized.

At this time, the automatic lifting cantilever 7 is used to lift it above the support platform 303, and then the piston rod of the second hydraulic cylinder 802 is extended downward until the bottom surface of the tower base 9 fits with the upper surface of the support platform 303. At this time, the wiring assembly 805 is de-energized, and the two electromagnetic suction assemblies 804 stop working and separate from the tower base 9, thereby completing the automatic lifting and loading process. The unloading process is the opposite of the above process and will not be described in detail here.

[0057] The working principle of this embodiment is as follows: during operation, the iron tower base 9 after spot welding is placed on the designated loading position on the rotating material changing platform 6 by manual or mechanical arms. When the iron tower base 9 to be processed rotates to the loading and unloading position, the automatic lifting cantilever 7 drives the entire electromagnetic suction suspension mechanism 8 to rotate to the appropriate position above the iron tower base 9. Then, the two electromagnetic suction components 804 on the electromagnetic suction suspension mechanism 8 adsorb and fix the iron tower base 9;

[0058] Then, the automatic lifting boom 7 is used to lift it above the support platform 303. Then, the piston rod of the second hydraulic cylinder 802 extends downward until the bottom surface of the tower base 9 is in contact with the upper surface of the support platform 303. At this time, the wiring assembly 805 is powered off, and the two electromagnetic suction assemblies 804 stop working, completing the separation from the tower base 9 and resetting.

[0059] At this time, the automatic positioning clamping mechanism 4 and the follow-up pre-adjustment mechanism 5 start to work. First, the follow-up pre-adjustment mechanism 5 adjusts the position of the tower base 9 to a suitable state, and then the multiple positioning clamps 404 complete the locking and fixing of the corresponding corners of the tower base 9;

[0060] During welding, the displacement adjustment mechanism 2 will drive the tower base 9 to freely adjust to various angles, and cooperate with the welding path programming of the welding robot 1, so that automatic welding can be performed according to the set welding program. After the welding is completed, the automatic lifting cantilever 7 and the electromagnetic suspension mechanism 8 will lift the tower base 9 to the rotating material changing platform 6.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
