Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to an adaptive positioning platform for automated welding equipment. Background Technology

[0002] The adaptive positioning platform of welding equipment is a welding auxiliary system. By performing welding operations through the adaptive positioning platform of the welding equipment, it can prevent workpiece deformation in traditional welding, reduce assembly errors, and avoid positioning deviations during welding, thereby improving the stability and consistency of welding quality.

[0003] Some welding equipment's adaptive positioning platform is equipped with multiple retractable units. When placing the workpiece, the platform can adjust the corresponding retractable units according to the workpiece's posture to form a suitable clamping surface or structure, thereby adapting to workpieces of different shapes and facilitating subsequent welding work.

[0004] However, since the distribution spacing of the telescopic units in the adaptive positioning platform of the welding equipment is fixed and the adjustment accuracy is limited, some telescopic units around the weldment may not be able to fully contact the surface of the workpiece. The resulting gap will cause uneven distribution of the clamping force of the platform on the weldment, which is prone to cause micro-displacement of the workpiece or local stress concentration during the welding process. Therefore, an adaptive positioning platform for automated welding equipment is proposed to address the above problems. Utility Model Content

[0030] 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.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] Please see Figure 1-9 This utility model provides a technical solution:

[0033] An adaptive positioning platform for automated welding equipment includes a welding worktable 1. A clamping table assembly 2 is mounted on the welding worktable 1. The clamping table assembly 2 includes a positioning base 21, a support plate 22 fixedly connected to the upper end of the positioning base 21, a protective shell 23 fixedly connected to the upper end of the positioning base 21, a locking assembly 24 fixedly connected to the upper end of the protective shell 23, a cover frame 27 fixedly connected to the upper end of the locking assembly 24 by bolts, a sealing plate 26 fixedly connected to the inner side of the cover frame 27 by adhesive bonding, a telescopic unit 25 inserted into the inner side of the sealing plate 26, and the locking assembly 24 includes a sandwich plate 241, with an air nozzle 24 fixedly connected to one side of the sandwich plate 241. 2. An airbag ring 243 is fixedly connected to the inner side of the sandwich panel 241. A magnetic vent valve 244 is fixedly connected to the inner side of the airbag ring 243. The telescopic unit 25 includes a support spring 251. A long rod 252 is fixedly connected to the upper end of the support spring 251. A sealing sleeve 253 is slidably connected to the outer side of the long rod 252. A magnetic air inlet 254 is fixedly installed on the outer side of the long rod 252. A guide block 255 is fixedly connected to the inner side of the long rod 252. A slanted groove 256 is opened on the inner side of the long rod 252. A rubber 257 is fixedly connected to the inner side of the slanted groove 256. A piston assembly 258 is slidably connected to the inner side of the long rod 252. A plastic bead 259 is provided on the inner side of the long rod 252.

[0034] As a further implementation of this solution, the outer side of the support plate 22 is in close contact with the inner side of the protective shell 23, and there is a gap between the locking component 24 and the support plate 22. The thickness of the cover frame 27 is the same as the thickness of the sealing plate 26 and the two are at the same height. The telescopic unit 25 passes through the locking component 24 and a part of it is exposed above the sealing plate 26. The design of the protective shell 23, the cover frame 27 and the sealing plate 26 can ensure the flatness and sealing of the overall structure. The telescopic unit 25 is partially exposed above the sealing plate 26, which facilitates interaction with the workpiece.

[0035] As a further implementation of this solution, the projection of the sandwich panel 241 in the vertical direction completely coincides with the projection of the cover frame 27 in the vertical direction. A cavity is provided on the inner side of the sandwich panel 241. The air nozzle 242 and the airbag ring 243 are connected through the cavity provided on the inner side of the sandwich panel 241. The cavity on the inner side of the sandwich panel 241 serves as a connecting channel between the air nozzle 242 and the airbag ring 243, providing an efficient gas transmission path. At the same time, the sandwich panel 241 also isolates the airbag ring 243 from the outside world, improving its reliability and service life.

[0036] As a further implementation of this solution, a support plate 22 is fixedly connected to the bottom end of the support spring 251. The support spring 251 and the long rod 252 are on the same axis. The upper end of the long rod 252 is arc-shaped. The angle between the long rod 252 and the airbag ring 243 is 90°. The coaxial design of the support spring 251 and the long rod 252 ensures the accurate transmission direction of force and ensures that the long rod 252 can move in the correct direction when subjected to force, thereby improving the motion accuracy and reliability of the entire device. The arc-shaped setting at the upper end of the long rod 252 can prevent it from scratching the surface of the workpiece when it comes into contact with the workpiece.

[0037] As a further implementation of this solution, the sealing sleeve 253 has an "I" shape in its horizontal projection. A sealing plate 26 is fixedly connected to the outside of the airbag ring 243. The magnetic air inlet 254 is located below the sealing sleeve 253. There are two magnetic air inlets 254, which are symmetrically distributed. The positions of the magnetic air inlets 254 correspond one-to-one with the positions of the magnetic air valve 244, and the two are magnetically attracted to each other. The sealing sleeve 253 can restrict the long rod 252 on the one hand, and prevent impurities generated during welding operations from entering the clamping table assembly 2 on the other hand.

[0038] As a further implementation of this solution, the guide block 255 is located at the upper end of the inclined groove 256. The inclined groove 256 is provided with several of them and is arranged in a circular array. The position of the rubber 257 corresponds one-to-one with the position of the inclined groove 256. Multiple plastic beads 259 are provided and are located in the gap formed between the piston assembly 258 and the air nozzle 242. This arrangement allows the plastic beads 259 to enter the inclined groove 256 from all directions when moving randomly, thereby squeezing the rubber 257 and making the rubber 257 expand better.

[0039] As a further implementation of this solution, the piston assembly 258 includes a piston block 2581, which is composed of a frustum and a cylinder. A guide rod 2582 is fixedly connected to the upper end of the piston block 2581. The upper end of the guide rod 2582 is arc-shaped. A return spring 2583 is fixedly connected to the upper end of the piston block 2581. A guide block 255 is fixedly connected to the upper end of the return spring 2583. The return spring 2583 is sleeved on the outside of the guide rod 2582. The shape of the piston block 2581 allows it to better push the plastic bead 259 away when it comes into contact with it. The arc-shaped design of the upper end of the guide rod 2582 allows it to smoothly enter the guide block 255.

[0040] Workflow: When using the device, the clamping table assembly 2 is placed on the welding worktable 1. The workpiece to be welded, which needs to be positioned and clamped, is then placed on the clamping table assembly 2. At this time, the workpiece, due to its own weight, presses down on the long rod 252. The compressed long rod 252 compresses the support spring 251 downwards, causing the positions of multiple long rods 252 to change, thus initially positioning and fixing the workpiece. Next, air is injected into the air bladder ring 243 through the air nozzle 242. When air is injected into the air bladder ring 243, the air bladder ring 243 will expand, thereby increasing the clamping force on the long rod 252 and preventing the compressed long rod 252 from accidentally resetting. As the workpiece is pushed, the magnetic air inlet 254 installed in the uncompressed long rod 252 will gradually decrease in distance from the magnetic air valve 244 fixed in the airbag ring 243 as the corresponding airbag ring 243 expands, eventually attracting each other. When the magnetic air inlet 254 and the magnetic air valve 244 are attracted together, a connection is formed between the magnetic air valve 244 and the magnetic air inlet 254. At this time, the air in the airbag ring 243 can enter the inside of the air nozzle 242 through the magnetic air valve 244 and the magnetic air inlet 254. The air entering the air nozzle 242 will push the piston assembly 258 upward. As the piston assembly 258 moves upward, the piston block 2581 drives the guide rod 2582 upward and inserts it into the guide block 255. Simultaneously, the sealing sleeve 253 deforms, allowing the piston block 2581 to move upward stably and precisely. Due to the special shape of the piston block 2581, it can better push the plastic bead 259 into the inclined groove 256 during movement, causing the plastic bead 259 to squeeze the rubber 257. This exposes a portion of the rubber 257 on the outside of the air nozzle 242, allowing it to contact the workpiece surface and further fix the workpiece, preventing incomplete adhesion. When the workpiece is clamped, after the welding operation is completed, the air injection into the air nozzle 242 is stopped. At this time, the air in the sandwich plate 241 and the air bag ring 243 is discharged from the air nozzle 242. The elastic force generated by the return spring 2583 restoring its deformation will drive the piston block 2581 and the guide rod 2582 to reset. After the piston block 2581 resets, the plastic bead 259 will slide out of the inclined groove 256. At the same time, the rubber 257 will also restore its deformation. After the workpiece is removed from the clamping table assembly 2, the long rod 252 is no longer squeezed by the workpiece or clamped by the air bag ring 243. It will quickly reset under the elastic force generated by the support spring 251.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
