Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a manual robot base. Background Technology

[0002] In bridge engineering, I-beams serve as the core load-bearing components of main beams, crossbeams, and supports, efficiently transferring vehicle loads and enhancing structural stability. Their bending resistance is particularly suitable for the support design of long-span bridges. In the shipbuilding industry, I-beams are relied upon to construct the hull frame, deck supports, and bulkhead frames. Corrosion-resistant high-strength steel must be used, and anti-corrosion coatings must be applied to resist seawater erosion. Welding is the key process for connecting I-beams.

[0003] In the aforementioned fields, there are scenarios where I-beams are arranged in long rows, while the range of motion of welding robots is limited. Moving the workpiece to be welded would greatly increase the complexity and difficulty of the work. Utility Model Content

[0004] This application provides a manual robot base to solve the problem of adjusting the welding position of a welding robot along an I-beam, thereby expanding the robot's welding range. This application also provides a welding device that uses the aforementioned manual robot base.

[0005] The first aspect of this application provides a manual robot base, comprising: Base; The first clamping mechanism, which is mounted on the base, includes: a first clamping rod, a second clamping rod, and a first adjusting component. The first clamping rod and the second clamping rod are hinged at the middle. The first clamping rod and the second clamping rod clamp the I-beam on both sides. The first adjusting component is mounted on the base and is used to adjust the included angle of the first clamping rod and the second clamping rod. The second clamping mechanism, connected to the base, includes: a jaw and a second adjusting component. The jaw is disposed on both sides of the I-beam and connected to the second adjusting component. The jaw is used to clamp the I-beam, and the second adjusting component is used to adjust the distance between the jaws.

[0006] The beneficial effects of the above embodiments are as follows: the first adjustment component and the second adjustment component facilitate the control of the clamping state of the first clamping mechanism and the second clamping mechanism. The first clamping mechanism and the second clamping mechanism form a multi-point clamping structure on both sides of the I-beam, which greatly improves the stability of the base positioning on the I-beam and can change the positioning position of the base on the I-beam, greatly expanding the welding range of the welding device on the base and meeting the welding requirements of the I-beam.

[0007] Based on the above embodiments, the embodiments of this application can be further improved as follows: In one embodiment of this application, the first clamping mechanism further includes guide rollers. The guide rollers are mounted at both ends of the first clamping rod and the second clamping rod, and are disposed on both sides of the edge of the I-beam. The guide rollers are used for rolling contact with the edge of the I-beam. The beneficial effects of this step are: the guide rollers, mounted at both ends of the clamping rods and rolling in contact with the edge of the I-beam, significantly reduce the frictional resistance when manually moving the base, thus improving positioning efficiency. Simultaneously, the rolling contact avoids scratching the I-beam, protecting the integrity of the workpiece.

[0008] In one embodiment of this application: the first clamping mechanism further includes an anti-tipping plate, which is connected to both ends of the first clamping rod and the second clamping rod. When the first clamping mechanism clamps the I-beam, the anti-tipping plate extends between the upper and lower edges of the I-beam. The beneficial effect of this step is that the anti-tipping plate, embedded between the upper and lower edges of the I-beam, forms a physical limiting structure, effectively preventing the base from tilting laterally due to vibration or external force during welding, thus improving the safety of high-altitude operations.

[0009] In one embodiment of this application: the first clamping mechanism further includes: a movable rod, the movable rod being hinged to the ends of the first clamping rod and the second clamping rod, and the guide roller and the anti-tipping plate being connected to the movable rod. The beneficial effect of this step: the hinged structure of the movable rod allows the guide roller and the anti-tipping plate to be quickly moved to the outside of the I-beam, facilitating the removal of the base from the I-beam.

[0010] In one embodiment of this application: the first clamping mechanism further includes an elastic element, which is disposed between the first clamping rod and the movable rod, and between the second clamping rod and the movable rod. The elastic element is used to keep the movable rod stable when it is in a folded state. The beneficial effects of this step are: the elastic element maintains the stability of the movable rod in its folded state, preventing the component from shaking or accidentally unfolding when not in operation, simplifying the operation process, reducing the storage volume of the device, and improving portability.

[0011] In one embodiment of this application: the first clamping mechanism further includes a rolling assembly, which is connected to the first clamping rod and the second clamping rod, and the rolling assembly makes rolling contact with the upper surface of the I-beam. The beneficial effects of this step are: the rolling assembly directly contacts the upper surface of the I-beam, sharing the load of the clamping mechanism, reducing frictional resistance during movement, and forming a multi-point rolling structure with the guide rollers, achieving smooth displacement of the base and reducing the intensity of manual pushing.

[0012] In one embodiment of this application: the first adjusting component includes: a first screw and an adjusting block. The first screw is rotatably connected to the base, and the adjusting block is threadedly connected to the first screw and slidably disposed on the base. The base has a limiting groove, and the first clamping rod and the second clamping rod are respectively inserted into the corresponding limiting groove. The beneficial effect of this step is that the position of the adjusting block is controlled by the threaded transmission, and the rotation of the first and second clamping rods is guided by the limiting groove, thereby achieving the function of controlling the opening and closing angle of the clamping rods.

[0013] In one embodiment of this application: the second adjusting component includes: a second screw, the second screw being rotatably connected to the base; a chuck threadedly connected to the second screw and slidably disposed on the base; the chuck having a slot for inserting the edge of the I-beam. The beneficial effect of this step is that the second screw drives the chuck to move synchronously and symmetrically, achieving rapid locking and releasing of the slot onto the edge of the I-beam.

[0014] In one embodiment of this application, it further includes a handle rod connected to the base. The advantage of this step is that the handle rod provides a fulcrum for manual movement, reducing operational intensity.

[0015] The second aspect of this application provides a welding apparatus, including the aforementioned manual robot base. The beneficial effects of this step are: the welding robot can achieve rapid positioning and stable clamping at any position on the I-beam using this base, expanding the robot's welding coverage and improving the efficiency of continuous operation of long weld seams.

[0020] In the description of this application, it should be understood that the directional terms or positional relationships described are based on the orientation or positional relationships shown in the accompanying drawings, or based on the orientation or positional relationships in actual use, and are only for the purpose of facilitating the description of the contents of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Example 1 like Figure 1-5 As shown, a manual robot base includes: a base 1, a first clamping mechanism 2, and a second clamping mechanism 3. The base 1 is used to mount a welding robot. The first clamping mechanism 2 is mounted on the base 1 and includes: a first clamping rod 201, a second clamping rod 202, and a first adjusting component. The first clamping rod 201 and the second clamping rod 202 are hinged at their middle parts. The first clamping rod 201 and the second clamping rod 202 clamp the I-beam on both sides. The first adjusting component is mounted on the base 1 and is used to adjust the included angle between the first clamping rod 201 and the second clamping rod 202. The second clamping mechanism 3 is connected to the base 1 and includes: claws 301 and a second adjusting component. The claws 301 are disposed on both sides of the I-beam and connected to the second adjusting component. The claws 301 are used to clamp the I-beam, and the second adjusting component is used to adjust the spacing between the claws 301.

[0022] Specifically, such as Figure 1-3As shown, the base 1 includes a top plate 101 and a surrounding plate 102. The surrounding plate 102 is installed around the lower perimeter of the top plate 101. The ends of the first clamping rod 201 and the second clamping rod 202 extend through corresponding through holes in the surrounding plate 102 to the outer sides of both ends of the base 1. The lower surface of the middle part of the first clamping rod 201 has a first recess, and the upper surface of the middle part of the second clamping rod 202 has a second recess. The first recess overlaps the second recess, so that the first clamping rod 201 forms a structure stacked on the second clamping rod 202, while extending to the base. The upper surfaces of the first clamping rod 201 and the second clamping rod 202 on the outer side are flush, and their lower surfaces are also flush. The first clamping mechanism 2 also includes a central shaft 203, which passes through the middle of the first clamping rod 201 and the second clamping rod 202 in a vertical direction and is rotatably connected to the first clamping rod 201 and the second clamping rod 202 (the central shaft 203 also passes through the first recess and the second recess). The upper end of the central shaft 203 is inserted into the through hole opened in the top plate 101, and the top plate 101 is positioned by the shoulder of the central shaft 203.

[0023] Specifically, such as Figure 2 , 4 As shown, the first clamping mechanism 2 further includes a guide roller 204, which is installed at both ends of the first clamping rod 201 and the second clamping rod 202. The guide roller 204 is disposed on both sides of the edge of the I-beam and is used for rolling contact with the edge of the I-beam. The guide roller 204, installed at both ends of the clamping rods and rolling in contact with the edge of the I-beam, significantly reduces the frictional resistance when manually moving the base, improves positioning efficiency, and at the same time, the rolling contact avoids scratching the I-beam and protects the integrity of the workpiece.

[0024] Specifically, such as Figure 2 , 4 As shown, the first clamping mechanism 2 further includes an anti-tipping plate 205. The anti-tipping plate 205 is connected to both ends of the first clamping rod 201 and the second clamping rod 202. When the first clamping mechanism 2 clamps the I-beam, the anti-tipping plate 205 extends between the upper and lower edges of the I-beam. The anti-tipping plate 205 is embedded between the upper and lower edges of the I-beam, forming a physical limiting structure, which effectively prevents the base from tilting laterally due to vibration or external force during welding, thus improving the safety of high-altitude operations.

[0025] Specifically, such as Figure 2 , 4As shown, the first clamping mechanism 2 further includes a movable rod 206, which is hinged to the ends of the first clamping rod 201 and the second clamping rod 202. The guide roller 204 and the anti-tipping plate 205 are both connected to the movable rod 206. The hinged structure of the movable rod 206 allows the guide roller 204 and the anti-tipping plate 205 to be quickly moved to the outside of the I-beam, facilitating the removal of the base from the I-beam.

[0026] Specifically, such as Figure 2 , 4 As shown, the hinged connection between the first clamping rod 201 and the movable rod 206 is the same as that between the second clamping rod 202 and the movable rod 206. The hinged structure of the first clamping rod 201 and the movable rod 206 will now be described in detail. Both ends of the first clamping rod 201 are equipped with hinge grooves, in which a pin is inserted laterally. The end of the movable rod 206 is equipped with an ear plate, which is inserted into the hinge groove and rotatably fitted onto the pin. A limiting plate is connected to the bottom surface of the end of the first clamping rod 201. The limiting plate is located at the hinge groove, and by limiting the ear plate, the movable rod 206 can rotate downwards to a position parallel to the first clamping rod 201.

[0027] Specifically, such as Figure 2 , 4 As shown, a clamping shaft is vertically connected to the end of the movable rod 206. The guide roller 204 is rotatably mounted on the clamping shaft. The anti-tipping plate 205 is located below the guide roller 204 and is rotatably mounted on the lower end of the clamping shaft. The anti-tipping plate 205 has three strip plates arranged radially along the guide roller 204. The included angle between the strip plates is 120°. When the guide roller 204 rolls into contact with the upper edge of the I-beam, no matter how the anti-tipping plate 205 rotates, at least one strip plate is located in the area between the upper and lower edges of the I-beam.

[0028] Specifically, such as Figure 2 , 4 As shown, the first clamping mechanism 2 further includes an elastic element 207. The elastic element 207 is disposed between the first clamping rod 201 and the movable rod 206, and between the second clamping rod 202 and the movable rod 206. The elastic element 207 is used to maintain the stability of the movable rod 206 when it is in a folded state. The elastic element 207 maintains the stability of the movable rod 206 in its folded state, preventing the component from shaking or accidentally unfolding when not in operation, simplifying the operation process, reducing the storage volume of the device, and improving portability.

[0029] Specifically, such as Figure 2 , 4As shown, the elastic element 207 is a tension spring. The tension spring connection structure between the first clamping rod 201 and the movable rod 206 is the same as the tension spring connection structure between the second clamping rod 202 and the movable rod 206. The tension spring connection structure between the first clamping rod 201 and the movable rod 206 will be described in detail below. Both the first clamping rod 201 and the movable rod 206 are equipped with connecting parts on their sides. The connecting parts can be hooks, bolts 208, etc. Taking bolt 208 as an example, bolt 208 is threadedly connected to the first clamping rod 201 and the movable rod 206. The hooks at both ends of the tension spring are respectively fitted onto bolt 208. When the movable rod 206 is folded upward, the tension of the tension spring allows the movable rod 206 to remain in the folded state.

[0030] Specifically, such as Figure 2 , 5 As shown, the first clamping mechanism 2 further includes a rolling assembly 209, which is connected to the first clamping rod 201 and the second clamping rod 202. The rolling assembly 209 makes rolling contact with the upper surface of the I-beam. The rolling assembly 209 directly contacts the upper surface of the I-beam, sharing the load of the clamping mechanism, reducing frictional resistance during movement, and forming a multi-point rolling structure with the guide roller 204, achieving smooth displacement of the base and reducing the intensity of manual pushing.

[0031] Specifically, such as Figure 2 , 5 As shown, the rolling assembly 209 uses a bullseye wheel, which is installed on the surface of the first clamping rod 201 and the second clamping rod 202 facing the I-beam. The ball bearings in the bullseye wheel contact the surface of the I-beam, making it easy for the operator to push the overall structure to move on the I-beam.

[0032] Specifically, such as Figure 2 , 5 As shown, the first adjustment assembly includes a first screw 210 and an adjustment block 211. The first screw 210 is rotatably connected to the base 1, and the adjustment block 211 is threadedly connected to the first screw 210 and slidably disposed on the base 1. The base 1 has a limiting groove 212, and the first clamping rod 201 and the second clamping rod 202 are respectively inserted into the corresponding limiting grooves 212. The position of the adjustment block 211 is controlled by threaded transmission, and the first clamping rod 201 and the second clamping rod 202 are guided to rotate through the limiting grooves 212, thereby realizing the function of controlling the opening and closing angle of the clamping rods.

[0033] Specifically, such as Figure 2 , 5As shown, the first screw 210 is rotatably connected to the side plate. The axis of the first screw 210 is perpendicular to the length direction of the I-beam. The outer end of the first screw 210 is connected to the first handwheel. The thread on the first screw 210 is divided into two sections, which are respectively set on both sides of the I-beam. The threads of the two thread sections have opposite directions. The adjusting block 211 is connected to a threaded sleeve. The thread of the threaded sleeve is adapted to the thread of the corresponding thread section. The upper end of the adjusting block 211 is slidably inserted into the first sliding groove opened on the bottom surface of the top plate 101. The first sliding groove is perpendicular to the length direction of the I-beam. By rotating the first screw 210, the adjusting block 211 is driven to move closer or further apart, thereby driving the first clamping rod 201 and the second clamping rod 202 to rotate around the central axis 203.

[0034] Specifically, such as Figure 2 , 3 As shown, the second adjustment assembly includes: a second screw 302, which is rotatably connected to the base 1; a pawl 301 is threadedly connected to the second screw 302 and slidably disposed on the base 1; the pawl 301 has a slot 303 for inserting the edge of the I-beam. The second screw 302 drives the pawl 301 to move synchronously and symmetrically, realizing the rapid locking and releasing of the slot 303 on the edge of the I-beam.

[0035] Specifically, such as Figure 2 , 3 As shown, the second screw 302 is rotatably connected to the side plate of the base 1. The axis of the second screw 302 is perpendicular to the length direction of the I-beam. The outer end of the second screw 302 is connected to a second handwheel. The thread on the first screw 210 is divided into two sections, which are respectively set on both sides of the I-beam. The threads of the two thread sections have opposite directions. The chuck 301 is connected to a threaded sleeve. The thread of the threaded sleeve is adapted to the thread of the corresponding thread section. The upper end of the chuck 301 is slidably inserted into the second sliding groove opened on the bottom surface of the top plate 101. The second sliding groove is perpendicular to the length direction of the I-beam. By rotating the second screw 302, the chuck 301 is driven to move closer or further apart, so as to realize the function of the chuck 301 clamping or releasing the edge of the I-beam.

[0036] Specifically, such as Figure 1 As shown, the manual robot base also includes: handles 4, which are connected to the base 1. There are two handles 4, which are symmetrically arranged at both ends of the top plate 101. The handles 4 provide a fulcrum for manual movement, reducing the intensity of operation.

[0037] When using this type of manual robot base, the welding robot is installed on the base 1. The first handwheel is rotated so that the guide rollers 204 clamp the two sides of the I-beam, pushing the base along the I-beam to the position to be welded. The second handwheel is rotated so that the chuck 301 clamps the upper edge of the I-beam, and then the welding operation is performed. After the welding operation of this section is completed, the second handwheel is rotated in the opposite direction so that the chuck 301 separates from the I-beam, and then the base is pushed along the I-beam to the next position to be welded. The above process is repeated to perform welding.

[0038] Example 2 A welding apparatus includes the manual robot base disclosed in Embodiment 1. The welding robot uses this base to achieve rapid positioning and stable clamping at any position on the I-beam, expanding the robot's welding coverage and improving the efficiency of continuous operation of long weld seams.
