Description

Technical Field

[0001] This utility model relates to the field of robot welding technology, specifically a detachable fixing device for robot welding. Background Technology

[0002] A welding robot is an industrial robot that performs welding tasks. It has three or more programmable axes and is used in industrial automation. To adapt to different applications, the mechanical interface of the robot's last axis is usually a connecting flange, which can be used to attach different tools or end effectors. A welding robot is essentially an industrial robot with a welding clamp or welding (cutting) torch mounted on its last axis flange, enabling it to perform welding, cutting, or thermal spraying. During use, the workpiece is fixed in place by a fixing device, and then the welding robot performs the welding.

[0003] As disclosed in patent application CN222359582U, a detachable fixing device for robotic welding includes a worktable with a groove at its upper end. A limiting groove is formed on the inner wall of the groove. A mounting seat is disposed inside the groove, and a bidirectional lead screw is threaded to the inner wall of the mounting seat. A protruding plate is fixedly connected to the top of the mounting seat, and an arc-shaped clamping plate is provided at the upper end of the mounting seat. The beneficial effects of this invention are: by removing the bolts, the fixing of the flat clamping plate is eliminated, and the flat clamping plate can be removed. The arc-shaped clamping plate can then be used to clamp and fix the workpiece, facilitating adjustment according to the shape of the workpiece.

[0004] While the aforementioned patent facilitates adjustments based on the shape of the workpiece, it requires disassembling bolts each time an adjustment is made, resulting in low efficiency. Utility Model Content

[0024] 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.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A detachable fixing device for robotic welding includes a clamping platform 1 and a clamping platform 2. An assembly mechanism is provided between the clamping platform 1 and the clamping platform 2. The assembly mechanism includes a convex groove 11. The convex groove 11 is opened inward at both ends of the clamping platform 1 and the clamping platform 2. A connector 12 is snapped between the two convex grooves 11. Several threaded grooves 13 are opened at both ends of the connector 12. Through grooves 14 are opened at both ends of the clamping platform 1 and the clamping platform 2. A fixing member 15 is threadedly connected between the through groove 14 and the threaded groove 13. The fixing member 15 is an internal hex bolt.

[0027] In this embodiment, by using the convex groove 11 and the connector 12 together, the clamp can be quickly disassembled or assembled simply by loosening the fixing part 15, without having to completely remove the bolts, which significantly simplifies the adjustment process and improves work efficiency.

[0028] like Figure 1 and Figure 3 As shown, guide grooves 3 are provided in the middle of clamping platform 1 and clamping platform 2. Clamping plates 4 are movably installed on both sides of the upper end of the guide grooves 3. V-grooves 10 are provided on the front of the clamping plates 4. A clamping mechanism is provided between the guide grooves 3 and the clamping plates 4. The clamping mechanism includes a bidirectional lead screw 5. The bidirectional lead screw 5 is movably installed inside the guide grooves 3. Movable blocks 6 are threaded to both ends of the bidirectional lead screw 5. A crank 7 is fixedly installed on the right end of the bidirectional lead screw 5. A disassembly mechanism is provided between the clamping plates 4 and the clamping mechanism. The disassembly mechanism includes a positioning rod 8. Positioning rods 8 are fixedly installed on both sides of the bottom end of the clamping plates 4. Positioning holes 9 matching the positioning rods 8 are provided at both ends of the movable blocks 6.

[0029] In this embodiment, the V-groove 10 of the clamping plate 4 is used in conjunction with the flat surface to flexibly adapt to workpieces with round, cylindrical and planar shapes, reducing the frequency of equipment replacement and lowering the complexity and cost of operation.

[0030] Working principle: During operation, firstly, depending on the size and shape of the workpiece, determine whether to assemble clamping platform 1 and clamping platform 2. If assembly is required, insert both ends of the connector 12 into the convex grooves 11 of clamping platform 1 and clamping platform 2 respectively, and fix the connector 12 to the clamping platform using the fixing piece 15 to complete the assembly. If clamping platform 1 or clamping platform 2 is used alone, assembly is not required. Next, place the workpiece on clamping platform 1 and clamping platform 2, and adjust the direction of clamping plate 4 according to the shape of the workpiece. If the workpiece is round or cylindrical, the V-groove 10 of clamping plate 4 faces the workpiece; if the workpiece is planar, the flat surface of clamping plate 4 faces the workpiece. Then, rotate the double-acting screw 5 by cranking handle 7. The rotation of double-acting screw 5 drives the movable block 6 to move in the guide groove 3. The movable block 6 is connected to clamping plate 4 through positioning rod 8 and positioning hole 9, thereby pushing clamping plate 4 towards the workpiece until the workpiece is firmly clamped.
