Description

Technical Field

[0001] The utility model relates to the technical field of mobile tracks, in particular to a mobile track of a welding robot. Background Art

[0002] Welding robots, as industrial robots that can automatically perform welding tasks, achieve efficient and precise welding operations through teaching programming or offline programming. They not only improve production efficiency, but also replace manual high-intensity, high-quality welding work to a certain extent. Various types of welding robots, such as arc welding, laser welding and spot welding robots, play an important role in automobile manufacturing, marine engineering and other fields.

[0003] The moving tracks of existing welding robots are generally on a plane to guide welding operations. However, when welding the curved surfaces of large tanks such as oil storage tanks and chemical storage tanks, parallel guide rails are difficult to meet the operation requirements. Therefore, a moving track pair of a welding robot is provided so that the welding robot can move along the large tank to complete the welding operation. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a moving track for a welding robot to solve the technical problem of insufficient adaptability of the moving track when the welding robot is welding the arc surface of a large tank.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a mobile track of a welding robot, comprising a flexible steel belt, a clamping mechanism, and a moving mechanism, wherein the clamping mechanism comprises a first clamping block, a first slide groove is provided on the top of the first clamping block, the first clamping block is engaged and slidably engaged with the first clamping groove, a second slide groove is provided on the top of the first clamping groove, a slider is engaged and slidably engaged with the second slide groove, and a push plate is provided on the outer surface of the slider;

[0006] The moving mechanism includes a housing, a buckle plate is provided on the back of the housing, a first mounting slot is provided on the buckle plate and one side of the housing, a roller is rotatably connected inside the first mounting slot, a second mounting slot is provided inside the housing, a rotating rod is provided inside the second mounting slot, a latching tooth is provided on the outer surface of the rotating rod, and a mounting base is provided on the outer surface of the housing;

[0007] The top of the flexible steel belt is fixedly connected with a guide rail, and the outer surface of the flexible steel belt is provided with a guide groove.

[0008] By adopting the above technical solution, the combination of the slider and the push plate makes the clamping process simpler and faster, and the connection or separation between the clamping blocks can be easily achieved by pushing the push plate.

[0009] Furthermore, two first clamping blocks are provided, and the two first clamping blocks are symmetrically arranged along the central axis of the flexible steel belt.

[0010] By adopting the above technical solution, by setting two first clamping blocks symmetrically along the central axis of the flexible steel belt, the structural stability of the clamping mechanism can be significantly improved. The two clamping blocks act together on the flexible steel belt to make the force more uniform, effectively preventing the deviation or distortion that may be caused by single-point force, thereby ensuring the stability and accuracy of the entire moving track.

[0011] Furthermore, the slider is adapted to the first sliding groove, and a slope is provided on the bottom of the slider.

[0012] By adopting the above technical solution, the slider is adapted to the first slide groove, ensuring that the clamping block can form a stable clamping structure when inserted into the clamping groove. This clamping method is simple and reliable, and can effectively prevent the flexible steel belt from loosening or falling off at the splicing point, thereby ensuring the stability and safety of the entire moving track.

[0013] Furthermore, the rollers are provided in two groups, each group of the rollers is provided with five rollers evenly and equidistantly arranged in a linear array, and the outer surfaces of the rollers are provided with a rubber layer.

[0014] By adopting the above technical solution, the rubber layer can make the roller adapt to the micro-curvature of the flexible steel belt after bending, so that the roller fits tightly to the surface of the guide rail.

[0015] Furthermore, the latching teeth are adapted to the guide grooves, and the mounting base is adapted to the external welding robot.

[0016] By adopting the above technical solution, the matching of the clamping teeth and the guide groove provides precise guidance for the movement of the moving mechanism on the flexible steel belt. This structure ensures that the moving mechanism can slide stably along the predetermined path, avoiding deviation from the track or unnecessary shaking, thereby improving the accuracy of welding.

[0017] Furthermore, a connecting column is provided on one side of the flexible steel belt, and a magnetic meter seat is provided on one end of the connecting column.

[0018] By adopting the above technical solution, the connecting column provides stable support for the magnetic table base, ensuring that the welding quality of the welding robot will not be affected by track movement or shaking during welding operations.

[0019] Furthermore, there are a plurality of magnetic meter bases, and the plurality of magnetic meter bases are evenly and equidistantly arranged in a linear array.

[0020] By adopting the above technical solution, by setting up a number of magnetic bases, and these magnetic bases are evenly distributed in a linear array, the stability of the flexible steel belt on the surface of the large tank can be significantly enhanced, providing greater adsorption force and more uniform support, thereby preventing the flexible steel belt from sliding or twisting during the welding process.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. This utility model achieves good adaptability and stable fit to the curved surface of large tanks by providing a flexible steel belt, a clamping mechanism, and a magnetic base. The flexible steel belt can fit tightly on the curved surface of the tank, and the strong magnetic adsorption of the magnetic base ensures the stability and reliability of the entire mobile track. The clamping mechanism enables multiple flexible steel belts to be easily clamped and spliced, further expanding the scope of application of the mobile track and enabling it to adapt to tanks of different diameters. The advantage of this structure is that it provides a flexible and efficient solution, enabling the welding robot to perform precise welding operations on tanks of various shapes and sizes.

[0023] 2. The utility model realizes the stable and precise movement of the welding robot on the flexible steel belt by setting a moving mechanism. The moving mechanism can slide smoothly on the flexible steel belt through the friction between the roller and the guide rail and the engagement of the clamping teeth and the guide groove, and can accurately control the movement trajectory and speed of the welding robot, thereby improving the operating efficiency and welding quality of the welding robot on the curved surface of large tanks, reducing the need for manual intervention and adjustment, and reducing labor intensity and cost. At the same time, the moving mechanism also enables the welding robot to more flexibly cope with complex welding environments and operating requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following describes an embodiment of the present invention based on its overall structure.

[0033] Example 1:

[0034] A mobile track for a welding robot, such as Figures 1-4As shown, including flexible steel belt 1, clamping mechanism 4 and moving mechanism 5, clamping mechanism 4 includes first clamping block 401, the top of first clamping block 401 is provided with first sliding groove 402, first clamping block 401 is clamped and slides first clamping groove 403, the top of first clamping groove 403 is provided with second sliding groove 404, second sliding groove 404 is clamped and slides sliding block 405, the outer surface of sliding block 405 is provided with push plate 406;

[0035] Moving mechanism 5 includes shell 501, the back of shell 501 is provided with buckle plate 502, buckle plate 502 and one side of shell 501 are provided with first installation slot 503, first installation slot 503 is rotatably connected with roller 504 in the inside, the inside of shell 501 is provided with second installation slot 506, second installation slot 506 is provided with rotating rod 507 in the inside, the outer surface of rotating rod 507 is provided with clamping tooth 508, the outer surface of shell 501 is provided with installation base 510;

[0036] The top of flexible steel belt 1 is fixedly connected with guide rail 505, the outer surface of flexible steel belt 1 is provided with guide groove 509, the combination of sliding block 405 and push plate 406 makes the clamping process more convenient and fast, by pushing push plate 406, the connection or separation between clamping blocks can be easily realized, guide rail 505 provides rolling path for roller 504, and guide groove 509 cooperates with clamping tooth 508 to ensure the stable and accurate movement of moving mechanism 5 on flexible steel belt 1.

[0037] Referring to Figure 3 、 Figure 4 , first clamping block 401 is provided with two, two first clamping blocks 401 are symmetrically arranged along the central axis of flexible steel belt 1, by arranging two first clamping blocks 401 symmetrically along the central axis of flexible steel belt 1, the structural stability of clamping mechanism 4 can be significantly improved, two clamping blocks act on flexible steel belt 1 together, so that the stress is more uniform, effectively preventing the deviation or distortion caused by single-point stress, thereby ensuring the stability and accuracy of the entire moving track, two symmetrically arranged first clamping blocks 401 can provide larger clamping area, increasing the contact points and friction force between clamping mechanism 4 and flexible steel belt 1, thereby enhancing the firmness of clamping.

[0038] Referring to Figure 3 、 Figure 4The slider 405 is adapted to the first slide groove 402, and the bottom of the slider 405 is provided with an inclined surface. The slider 405 is adapted to the first slide groove 402, ensuring that the first clamping block 401 can form a stable clamping structure when inserted into the first clamping groove 403. This clamping method is simple and reliable, and can effectively prevent the flexible steel belt 1 from loosening or falling off at the splicing point, thereby ensuring the stability and safety of the entire moving track. When the first clamping block 401 is fully inserted into the first clamping groove 403, the slider 405 will be guided by the inclined surface and fall into the deepest part of the first slide groove 402. At this time, due to the effect of the inclined surface, the slider 405 is not easily ejected accidentally, thereby enhancing the safety of the clamping structure.

[0039] See Figure 3 There are two groups of rollers 504, and each group of rollers 504 is evenly spaced and arranged in a linear array. The outer surface of the roller 504 is provided with a rubber layer. The rubber layer can make the roller adapt to the micro-arc after the flexible steel belt is bent, so that the roller fits tightly on the surface of the guide rail. Since each group of rollers 504 is evenly arranged with five, the load capacity of the mobile track is enhanced. Multiple rollers share the weight, so that the mobile mechanism can withstand a larger load, which is suitable for welding robots of different weight levels.

[0040] See Figure 3 The latch teeth 508 are adapted to the guide groove 509, and the mounting base 510 is adapted to the external welding robot. The adaptation of the latch teeth 508 to the guide groove 509 provides precise guidance for the movement of the mobile mechanism 5 on the flexible steel belt 1. This structure ensures that the mobile mechanism 5 can slide stably along the predetermined path, avoids deviation from the track or unnecessary shaking, thereby improving the welding accuracy. The mounting base 510 is adapted to the external welding robot, and the mobile track can be used in conjunction with various models of welding robots, ensuring the stability of the welding robot during operation.

[0041] Example 2:

[0042] See Figure 1 、 Figure 2 A connecting column 2 is provided on one side of the flexible steel belt 1, and a magnetic table base 3 is provided at one end of the connecting column 2. The connecting column 2 provides stable support for the magnetic table base 3, ensuring that the welding robot will not be affected by the movement or shaking of the track during welding operations. The connecting column 2 and the magnetic table base 3 are detachable, which makes the installation and disassembly process simpler and faster.

[0043] See Figure 1 、 Figure 2There are several magnetic bases 3, and several magnetic bases 3 are evenly and equidistantly arranged in a linear array. By setting up several magnetic bases 3, and these magnetic bases 3 are evenly and equidistantly distributed in a linear array, the stability of the flexible steel belt 1 on the surface of the large tank can be significantly enhanced, providing greater adsorption force and more uniform support, thereby preventing the flexible steel belt 1 from sliding or twisting during the welding process. Since the magnetic bases 3 are evenly distributed, this structure enables the movable track to adapt to large tanks with different curvatures and diameters, and the magnetic bases 3 can provide stable support points.

[0044] The implementation principle of the present invention is as follows: first, the magnetic base 3 of the flexible steel belt 1 is attached to the outer surface of the large tank body, and then the knob of the magnetic base 3 is rotated to make the magnetic base 3 adsorbed on the outer surface of the tank body, and then the first clamping block 401 is inserted into the first clamping groove 403. During the insertion process, the first clamping block 401 lifts the slider 405 through the inclined surface. When it is fully docked, the slider 405 falls into the first slide groove 402 by gravity to clamp the first clamping block 401. Multiple flexible steel belts 1 can be selected according to the diameter of the tank body for clamping and splicing and adsorbed by the magnetic base 3. Then, the moving mechanism 5 is slid in from one end of the flexible steel belt 1. The rubber layer of the roller 504 can make the roller adapt to the micro-arc after the flexible steel belt is bent. It can be driven by the internal motor to rotate and rub against the guide rail 505 to make the moving mechanism 5 move along the flexible steel belt 1. At the same time, as the moving mechanism 5 moves, the card tooth 508 rotates and continuously engages with the guide groove 509.

[0045] Parts not involved in the present invention are the same as those in the prior art or can be implemented by using the prior art, and will not be described in detail here.
