Description

Technical Field

[0001] This utility model relates to the field of robot application technology, and in particular to a comprehensive operating table for robot welding. Background Technology

[0002] Welding, as one of the core processes of modern industrial manufacturing, is widely used in aerospace, automobile manufacturing, rail transportation, and shipbuilding, and is a key technology for connecting and forming metal structural components. Traditional welding processes rely heavily on manual operation. With the development of industrial automation technology, automated welding systems, through the integration of robotic arms, program control, and sensor technology, have significantly improved welding accuracy and production efficiency, becoming an important development direction in the field of intelligent manufacturing.

[0003] Existing robotic welding equipment typically employs multi-axis robotic arms to execute preset welding programs, with workpieces fixed to a steel plate on the welding worktable using specialized fixtures. To accommodate workpieces of varying sizes, the steel plate often features regularly arranged through holes, allowing the fixtures to be quickly adjusted in position and rotated, thus enabling flexible production. While this design addresses workpiece adaptability to some extent, significant drawbacks remain during equipment operation.

[0004] The core problem with current equipment is that welding slag produced during welding operations falls directly onto the steel plate surface, especially accumulating around through-holes. This slag buildup not only hinders the precise fit between the fixture and the steel plate, causing fixture misalignment or instability, but also limits the effective utilization of the through-holes, forcing operators to frequently adjust the fixture layout to avoid slag-covered areas. Furthermore, the high-temperature contact between the welding slag and the steel plate surface easily creates stubborn adhesion, requiring significant manpower and time for subsequent cleaning, and potentially leading to equipment malfunctions or reduced welding quality due to incomplete cleaning. Utility Model Content

[0005] To overcome the drawback of welding slag interfering with fixture installation, this utility model provides an integrated operating platform for robot assembly welding, aiming to solve the above-mentioned shortcomings.

[0006] A comprehensive operating platform for robotic welding includes a welding robot. A placement frame is provided on the front side of the welding robot. A collection box is slidably connected inside the placement frame. Slide grooves are opened at both the front and rear ends of the top of the placement frame. Both ends of a connecting block are slidably connected to the slide grooves. The connecting block has several locking holes spaced apart. A threaded rod is threadedly connected to one end of the connecting block, and a guide rod is slidably connected to the other end. The threaded rod is press-fitted with the placement frame, and the guide rod is slidably connected to the placement frame.

[0007] As a further preferred embodiment, several push rods are slidably connected to the left and right sides of the connecting block. The end of each push rod passes through the connecting block and communicates with the locking hole. A contact wheel is rotatably connected to one end of the push rod inserted into the locking hole. A return spring is sleeved on the push rod. One end of the return spring is connected to the push rod, and the other end is connected to the connecting block.

[0008] As a further preferred embodiment, the connecting block is connected to several inner rings on both its left and right sides. The inner rings are wrapped around the outer ring of the reset spring. The end of the push rod away from the connecting block is connected to a protective ring, which is wrapped around the outer ring of the inner ring.

[0009] As a further preferred embodiment, a limiting plate is connected to the bottom rear end of the placement rack, and the limiting plate cooperates with the collection box for limiting.

[0010] As a further preferred embodiment, the top surface of the base plate of the placement rack is rotatably connected to several rollers, and the rollers are in rolling connection with the bottom surface of the collection box.

[0011] As a further preferred embodiment, scrapers are connected to both the left and right sides of the front and rear ends of the connecting block, and the scrapers are slidably connected to the placement frame.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. By using a suspended placement frame and a collection box filled with clean water below, the welding slag generated during the welding process falls directly into the box and comes into contact with the clean water, achieving rapid cooling and solidification of the welding slag, reducing the interference of welding slag on the installation position of the fixture, and reducing the difficulty of subsequent cleaning.

[0014] 2. By setting a scraper on the side wall of the connecting block, the scraper and the surface of the placement frame form a sliding fit when the connecting block moves along the slide, thereby achieving the function of scraping off welding slag or debris in the slide, ultimately keeping the slide clean and ensuring smooth sliding of the connecting block.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0021] Example: A comprehensive operating platform for robotic welding, such as... Figures 1-4 As shown, the assembly includes a welding robot 1, a placement frame 2, a collection box 3, a connecting block 5, a threaded rod 7, and a guide rod 8. The placement frame 2 is located on the front side of the welding robot 1. The collection box 3 is slidably connected inside the placement frame 2. The top and both ends of the placement frame 2 have sliding grooves 4. Both ends of the connecting block 5 are slidably connected to the sliding grooves 4. The sliding grooves 4 provide a horizontal moving track for the connecting block 5. The connecting block 5 has several slotted holes 6, which provide a standard installation interface for the fixture. One end of the connecting block 5 is threadedly connected to the threaded rod 7, and the other end is slidably connected to the guide rod 8. The threaded rod 7 is pressed into the placement frame 2, and the guide rod 8 is slidably connected to the placement frame 2.

[0022] like Figure 1 and Figure 3 As shown, it also includes a push rod 9, a return spring 10, and a contact wheel 11. Several push rods 9 are slidably connected to the left and right sides of the connecting block 5. The ends of the push rods 9 pass through the connecting block 5 and communicate with the locking holes 6. The number of push rods 9 is twice that of the locking holes 6. The end of the push rod 9 inserted into the locking hole 6 is rotatably connected to the contact wheel 11. The return spring 10 is sleeved on the push rod 9. One end of the return spring 10 is connected to the push rod 9, and the other end is connected to the connecting block 5. When the clamp is inserted, it makes rolling contact with the contact wheel 11 on the side wall of the connecting block 5. The return spring 10 is stretched and stores elastic potential energy. The elastic force acts in the opposite direction on the contact wheel 11 through the push rod 9, making it stick tightly to the side wall of the clamp.

[0023] like Figure 1 and Figure 3As shown, it also includes an inner ring 12 and a protective ring 13. Several inner rings 12 are connected to both sides of the connecting block 5. The inner rings 12 are wrapped around the outer ring of the return spring 10. The end of the push rod 9 away from the connecting block 5 is connected to a protective ring 13. The protective ring 13 is wrapped around the outer ring of the inner ring 12. Through the expansion and contraction of the inner ring 12 and the protective ring 13, the return spring 10 is completely isolated from the area of ​​welding slag spatter, thereby achieving the clean protection of the spring's working environment.

[0024] like Figure 4 As shown, it also includes a limiting plate 14. The bottom rear end of the placement frame 2 is connected to the limiting plate 14. The limiting plate 14 and the collection box 3 are in a limiting cooperation. Through the abutting cooperation between the limiting plate 14 and the collection box 3, the collection box 3 is always located directly below the placement frame 2, thereby achieving precise coverage of the welding slag landing point.

[0025] like Figure 4 As shown, it also includes rollers 15. Several rollers 15 are rotatably connected to the top surface of the bottom plate of the placement frame 2. The rollers 15 are rotatably connected to the bottom surface of the collection box 3. Through the rolling cooperation between the rollers 15 and the collection box 3, the movement of the box is smoother, thereby realizing the convenient operation of manually cleaning welding slag.

[0026] like Figure 2 As shown, it also includes a scraper 16. The left and right sides of both ends of the connecting block 5 are connected to the scraper 16, and the scraper 16 is slidably connected to the placement frame 2.

[0027] During welding preparation, the workers need to adjust the distance between the two connecting blocks 5 according to the size of the workpiece to be welded to ensure the fixed clamping effect of the workpiece. The workers first loosen the threaded rod 7 so that the connecting block 5 can slide in the slide groove 4. Then, they push the connecting block 5 to move left and right along the slide groove 4. The guide rod 8 then slides in the slide groove 4 to maintain the stability of the connecting block 5 during the sliding process. When the two connecting blocks 5 are adjusted to the position that matches the width of the workpiece, the threaded rod 7 is tightened in the opposite direction so that it is pressed and fixed against the side wall of the placement frame 2, thus completing the positioning of the connecting block 5. In this stage, the sliding adjustment and threaded fixation ensure that the distance between the connecting blocks 5 can flexibly adapt to workpieces of different specifications, providing a stable foundation for the subsequent installation of the fixture.

[0028] Then, select a suitable clasp 6 and insert the clamp into the selected clasp 6. When the clamp is inserted into the clasp 6, it rolls and connects with the contact wheel 11. After being squeezed by the clamp, the contact wheel 11 slides outward, driving the push rod 9 to move outward synchronously. At this time, the protective ring 13 slides along the outer wall of the inner ring 12, and the return spring 10 is stretched and stores elastic potential energy. The elastic force of the return spring 10 acts in the opposite direction to the contact wheel 11 through the push rod 9, so that the contact wheel 11 fits tightly against the side wall of the clamp, forming a stable squeezing effect and preventing the clamp from loosening.

[0029] After the fixtures are secured, the workpiece is placed between all the fixtures and locked, and the welding robot 1 is started to perform the operation. The welding slag generated during the welding process falls directly into the collection box 3 below. A small amount of water pre-filled in the box can quickly cool the welding slag and prevent it from sticking to the box body at high temperature. At the same time, the telescopic structure formed by the inner ring 12 and the protective ring 13 always wraps around the return spring 10 to prevent welding slag from splashing onto the spring surface and affecting its mechanical properties.

[0030] After the welding process is completed, the clamp is released from the workpiece, and the workpiece and the clamp are removed in sequence. The clamp is pulled upward along the locating hole 6 and finally disengages from the connecting block 5. When the clamp is pulled out, the contact wheel 11 rolls in the opposite direction, the push rod 9 retracts under the elastic force of the return spring 10, the protective ring 13 slides back along the inner ring 12, and the telescopic structure returns to its initial state.

[0031] Subsequently, the workers loosened the threaded rod 7 again, pushing the two connecting blocks 5 to slide outwards and separate. During this process, the scraper 16 on the side wall of the connecting block 5 slid along the surface of the placement frame 2, scraping the welding slag or debris accumulated in the chute 4 into the collection box 3, keeping the chute 4 clean to ensure smooth subsequent sliding. After the connecting block 5 was reset, the threaded rod 7 was tightened again to fix it. Finally, the collection box 3 was pulled out using the handle on the front side: the roller 15 rolled on the bottom surface of the placement frame 2, reducing friction and allowing the collection box 3 to slide out smoothly. After emptying the welding slag, the empty box was pushed back into the placement frame 2, and the limiting plate 14 abutted against the rear end of the collection box 3, accurately positioning it directly below the placement frame 2. When using it again, simply add an appropriate amount of clean water to the collection box 3 to proceed to the next round of operation.

[0032] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
