[0034] Example

[0035] See also Figure 1-Figure 9 The present invention provides a technical solution: an adaptive steel bar welding robot docking system, comprising:

[0036] The placement part 1 includes a slide rail base 11, and the slide rail base 11 is slidably connected to a fixing seat 12 through a slide rail provided inside the slide rail base 11. Two fixing seats 12 are provided and symmetrically distributed above the slide rail base 11;

[0038] The top of the limiting column 23 is fixedly connected with a bevel gear 231, and a pressing assembly 232 is provided at one end of the limiting column 23 away from the bevel gear 231. There are two groups of limiting columns 23, each group is provided with three, and each group of limiting columns 23 has three columns arranged in a circle around the axis in the space surrounded by the lower clamping plate 21 and the upper clamping plate 22, which can better clamp the steel bar.

[0039] The adjustment assembly 24 includes an upper ring plate 241 and a lower ring plate 242. A slide groove 243 is provided inside the lower clamping plate 21 and the upper clamping plate 22. The upper ring plate 241 is slidably connected to the slide groove 243 by a slider 2431 fixedly connected to the inner side thereof. The lower ring plate 242 and the upper ring plate 241 adopt the same structural design. The lower ring plate 242 is slidably connected to the outer surface of the lower clamping plate 21. A ratchet groove 244 is provided on the outer surface of the upper ring plate 241.

[0040] The upper ring plate 241 is slidably connected to a bevel gear block 245 meshing with the bevel gear 231 through a groove body opened inside the upper ring plate 241 , and a compression spring 246 connected to the bevel gear block 245 is provided through a cavity opened inside the upper ring plate 241 .

[0041] The interior of the upper clamping plate 22 is rotatably connected to a pawl 2441 engaged with the ratchet groove 244 via an axial rod. A spring 2442 connected to the upper clamping plate 22 is provided on the side of the pawl 2441 away from the upper ring plate 241. Each set of ratchet grooves 244 and pawls 2441 is provided with three in a circumferential array.

[0042] The outer surface of the slider 2431 and the inner wall of the slide groove 243 are both designed to be magnetic, and a connecting rod 25 is slidably connected between the upper ring plate 241 and the lower ring plate 242 at a side away from the rotating shaft.

[0043] The pressing assembly 232 includes an elastic member 2321 connected to one end of the limiting column 23 away from the bevel gear 231 , and a rubber block 2322 is connected to the side of the elastic member 2321 away from the limiting column 23 , and the rubber block 2322 can better press the steel bar.

[0044] A limiting plate 13 for reserving external steel bar welds is slidably connected to the middle upper surface of the slide rail base 11. The limiting plate 13 can reserve welds for butt welding, thereby improving processing quality.

[0045] The process of positioning the steel bars:

[0046] In practical applications, when the ends of two external steel bars are butt-welded, the two steel bars need to be inserted into the positioning parts 2 on both sides of the limit plates 13 in the placement part 1, or the shaft set between the upper clamping plate 22 and the lower clamping plate 21 is rotated by an external driving device to drive the upper clamping plate 22 to rotate outward with the shaft as the center. The upper clamping plate 22 and the lower clamping plate 21 are designed with a bevel at the edge of one side close to the shaft. When the upper clamping plate 22 rotates, the bevel of the upper clamping plate 22 abuts against the bevel of the lower clamping plate 21. At this time, it is opened to the maximum extent and does not affect the taking and placing of the external steel bars. The bevel tooth block 245 is set on one side of the adjustment component 24, which does not affect the opening of the upper clamping plate 22. When placing the steel bars, the ends of the steel bars need to be kept at a certain distance from the ports of the upper clamping plate 22 and the lower clamping plate 21 to avoid affecting the positioning part 2 during welding.

[0047] After the steel bar is placed, or the shaft set between the upper clamping plate 22 and the lower clamping plate 21 is rotated by an external driving device, the upper clamping plate 22 is driven to rotate inward with the shaft as the center, and the upper clamping plate 22 and the side of the lower clamping plate 21 away from the shaft are in contact, and the steel bar is placed in the circumferential space surrounded by the upper clamping plate 22 and the lower clamping plate 21. The slider 2431 and the inner wall of the slide groove 243 are both designed with strong magnets. In the initial state, the side of the slider 2431 close to the limit column 23 and the inner wall of the slide groove 243 close to the limit column 23 are attracted by magnetism.

[0048] During the rotation process, the connection between the upper ring plate 241 and the lower ring plate 242 is in contact with each other. When the connecting rod 25 slidably connected to the inside of the lower ring plate 242 is pulled to rotate, the connecting rod 25 gives a thrust to the upper clamping plate 22 and a pulling force to the lower clamping plate 21; when the connecting rod 25 slidably connected to the inside of the upper ring plate 241 is pulled to rotate, the connecting rod 25 gives a pulling force to the upper clamping plate 22 and a thrust to the lower clamping plate 21, thereby synchronously driving the upper ring plate 241 and the lower ring plate 242 to rotate.

[0049] Hold the connecting rod 25 that is slidably connected to the inside of the lower ring plate 242 tightly, rotate clockwise with the axis of the upper clamping plate 22 and the lower clamping plate 21 as the center of the circle, the connecting rod 25 at the lower ring plate 242 is engaged with the inside of the lower ring plate 242, the connecting rod 25 and the lower ring plate 242 are relatively stationary, and the connecting rod 25 and the lower ring plate 242 rotate relative to the upper clamping plate 22 and the lower clamping plate 21. During the rotation process, the bevel gear block 245 rotates clockwise along with the upper ring plate 241 and the lower ring plate 242, and the bevel gear block 245 meshes with the bevel gear 231. During the rotation process of the bevel gear block 245, the bevel gear 231 rotates passively. Since the bevel gear 231 is fixedly connected to the limiting column 23, the limiting column 23 also rotates. There are three limiting columns 23 in total, and they are distributed in an array around the circumference of the circle surrounded by the upper clamping plate 22 and the lower clamping plate 21 as the axis. Since the outer surface of the limit column 23 is provided with a threaded groove matching the inner part of the upper clamp plate 22 and the lower clamp plate 21, the limit column 23 as a whole will follow the movement of the connecting rod 25 to press down on the inner steel bars of the upper clamp plate 22 and the lower clamp plate 21, and the pressure component 232 located at the bottom of the limit column 23 gradually approaches the outer surface of the steel bars.

[0050] During this process, the slider 2431 will move clockwise in the slide groove 243, and the ratchet groove 244 will rotate clockwise together. The pawl 2441 engaged with the ratchet groove 244 will be continuously squeezed downward as the upper ring plate 241 and the lower ring plate 242 rotate. When the pawl 2441 moves to the notch of the next ratchet groove 244, due to the elastic potential energy of the spring 2442, the pawl 2441 will be squeezed into engagement with the notch of the ratchet groove 244.

[0051] When the rubber block 2322 is away from the outer surface of the limiting column 23 and fits the outer surface of the steel bar, the connecting rod 25 continues to be given a force to rotate, so that the pawl 2441 enters the next ratchet groove 244. At this time, the elastic member 2321 is also squeezed and compressed, and the rubber block 2322 is deformed to a certain extent. The connecting rod 25 cannot move further. At this time, the pawl 2441 and the ratchet groove 244 are in a clamping state. Due to the unidirectional movement characteristics of the ratchet groove 244, the pawl 2441 clamps and fixes the upper ring plate 241 and the lower ring plate 242, as well as the position of the limiting column 23 through the meshing ratchet groove 244. The pressing components 232 at the bottom of the limiting columns 23 in three directions jointly position and clamp the steel bars, and at this time, the steel bars are at the axis of the space between the upper clamp plate 22 and the lower clamp plate 21. Since four elastic members 2321 and rubber blocks 2322 are evenly arranged around the limiting column 23, no matter what angle the limiting column 23 rotates to, the rubber blocks 2322 can wrap the steel bars more completely after contacting them, and the contact area with the outer surface of the steel bars becomes larger. Accordingly, the steel bars on both sides of the limiting plate 13 are tightly pressed and fixed by the positioning part 2.

[0052] The process of butt welding steel bars:

[0053] After the steel bars on both sides of the limit plate 13 are fixed, start the distribution box, the electric slide rail inside the slide rail base 11 starts to operate, and the fixed seats 12 on both sides of the limit plate 13 move towards each other. When the end of the steel bar contacts the outer surface of the limit plate 13, the electric slide rail inside the slide rail base 11 stops moving, and the limit plate 13 is removed from the slide rail base 11 manually or by a push-pull mechanism (the thickness of the limit plate 13 depends on the weld length required for the butt welding process. The weld is reserved in advance to ensure the consistency of welding quality). After the limit plate 13 is removed, the ends of the two steel bars are butt-welded using a welding machine.

[0054] The process of removing the steel bars after welding is completed:

[0055] After the butt welding is completed, the steel bars are processed into a whole, and the upper ring plates 241 and the lower ring plates 242 on both sides are pushed outward, and the side of the slider 2431 away from the limit column 23 is attracted to the inner wall of the slide groove 243 away from the limit column 23, and the compression spring 246 that has been in a compressed state in the internal cavity of the upper ring plate 241 and the lower ring plate 242 is released, and the surface of the side of the bevel gear block 245 close to the upper ring plate 241 and the lower ring plate 242 is attracted to the upper ring plate 241 and the lower ring plate 242 away from the limit column. The outer surface of 23 fits together, and the bevel gear block 245 and the bevel gear 231 always keep in meshing state, that is, the upper ring plate 241 and the lower ring plate 242 are displaced to the side away from the limiting column 23, and the slider 2431 in the slide groove 243 also moves to the side away from the limiting column 23, and the lower end of the slider 2431 extends to the inner wall of the upper clamping plate 22 and the lower clamping plate 21 and fits therewith, ensuring that the upper ring plate 241 and the lower ring plate 242 are always in contact with the upper clamping plate 22 and the lower clamping plate 21 during the movement.

[0056] The width of the slide groove 243 is greater than that of the upper ring plate 241. The width of the upper ring plate 241 is the same as that of the ratchet groove 244 and the pawl 2441. After the upper ring plate 241 and the lower ring plate 242 are offset, the ratchet groove 244 moves together, and the ratchet groove 244 is no longer subject to the limiting force of the pawl 2441 and can rotate in the opposite direction.

[0057] When the upper ring plate 241 and the lower ring plate 242 on both sides move in opposite directions, the distance between them increases. Since the length of the connecting rod 25 is greater than the distance between the upper ring plate 241 and the lower ring plate 242 after the position change, and limit blocks are set at both ends of the upper ring plate 241 and the lower ring plate 242, they will not deviate outward.

[0058] At this time, the two connecting rods 25 are on the upper surface of the upper clamping plate 22, close to the top limit column 23. Since the bevel gear block 245 and the bevel gear 231 are still in a meshing state, pull the connecting rod 25 that slides inside a pair of lower ring plates 242, or pull the two connecting rods 25 at the same time to rotate counterclockwise, and the bevel gear block 245 follows to rotate counterclockwise. In this process, the bevel gear 231 rotates together with the bevel gear block 245, and the limit column 23 is rotated, so that the limit column 23 gradually moves outward following the direction of movement of the thread groove, and the bottom steel bar and the pressing component 232 are gradually separated, and the elastic member 2321 and the rubber block 2322 restore their elastic potential energy, waiting for the next pressing.

[0059] After the connecting rod 25 is gradually restored to the initial state, the axis of the two connecting rods 25 is located between the upper clamping plate 22 and the lower clamping plate 21, and the gap between the upper clamping plate 22 and the lower clamping plate 21 is at the same position as the gap between the upper ring plate 241 and the lower ring plate 242. The upper ring plate 241 and the lower ring plate 242 on both sides are moved inward, and the side of the slider 2431 close to the limit column 23 is attracted to the inner wall of the slide groove 243 close to the side of the limit column 23, and the compression spring 246 in the internal cavity of the upper ring plate 241 and the lower ring plate 242 in the loose state is compressed between the bevel gear block 245 and the upper ring plate 241 or the lower ring plate 242. The two connecting rods 25 slide with the upper ring plate 241 and the lower ring plate 242 respectively, and have no effect on the upper ring plate 241 and the lower ring plate 242 when they are displaced.

[0060] At this time, an external driving device is used to rotate the rotating shaft set between the upper clamping plate 22 and the lower clamping plate 21, driving the upper clamping plate 22 to rotate outward with the rotating shaft as the center, and the oblique mouth of the upper clamping plate 22 is abutted against the oblique mouth of the lower clamping plate 21. At this time, it is opened to the maximum extent, and an external robotic arm can be used to move a complete steel bar to the next process. At this point, one steel bar docking is completed.

[0061] To sum up, the process of butt jointing steel bars has the following advantages:

[0062] Advantage 1: A slide rail base 11 is provided to connect the two fixing seats 12, and the welding ends of the two steel bars are moved toward the middle together, eliminating manual intervention and improving production efficiency. When the steel bars are butt-jointed, a limit plate 13 is placed between the two steel bars. The thickness of the limit plate 13 is determined according to the welding process specification. When welding is required, the limit plate 13 is removed to leave a weld for welding. The limit plate 13 ensures the consistency and quality of the steel bar weld and reduces human errors.

[0063] Advantage 2: The positioning parts 2 on both sides are provided with limiting columns 23 in three directions, which can position and clamp the steel bars between the upper clamping plate 22 and the lower clamping plate 21 to ensure that the steel bars will not move during welding.

[0064] Advantage three: the positioning parts 2 on both sides have the same structure, and the limit columns 23 in three directions rotate at the same time, and synchronously clamp the upper clamping plate 22 and the lower clamping plate 21, which can ensure that the axes of the two steel bars are consistent, improve the welding accuracy, avoid misalignment, and enhance the bearing capacity of the steel bars and the stability of the structure.

[0065] Advantage 4: The space enclosed by the upper clamping plate 22 and the lower clamping plate 21 is relatively large, which can meet the needs of butt welding of steel bars of different diameters, has higher flexibility and versatility, and can adapt to butt welding of steel bars of different specifications.

[0066] Advantage 5. After the two steel bars are butt-jointed, they become a whole. The upper clamping plate 22 and the lower clamping plate 21 are designed to be openable and separable, which is not affected by the length of the steel bars. Inserting and removing the steel bars becomes more convenient and quick, and can be easily installed on the steel bars, especially when the steel bars are partially fixed or the space is limited.

[0067] Advantage 6: There are four groups of elastic members 2321 and rubber blocks 2322 in the pressing assembly 232. When the limiting column 23 is pressed against the steel bar, the contact area between the rubber block 2322 and the outer surface of the steel bar becomes larger, thereby enhancing the stability during positioning.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
