Description

Technical Field

[0001] The utility model relates to the technical field of robot automatic welding tooling, in particular to a special tooling for automatic double-station welding of a bucket body of a bucket elevator. Background Art

[0002] The automatic welding technology of bucket elevator is an important progress in modern manufacturing process, which aims to improve welding quality and production efficiency, while reducing labor intensity and production cost. This technology is mainly used in the batch production of bucket elevator (i.e. the bucket used to lift materials). The following are its main features and application principles:

[0003] Technical features: 1. High degree of automation: Automatic welding systems are usually integrated with advanced robotic arms, which can accurately execute welding paths through programming control to ensure the consistency and quality of each welding.

[0004] 2. Stable welding quality: Compared with manual welding, automatic welding can more accurately control welding parameters such as current, voltage, welding speed, etc., reduce welding defects such as uneven welds, pores, cracks, etc., thereby improving the overall quality and reliability of welded parts.

[0005] 3. Improve production efficiency: The automatic welding process is continuous and fast, which reduces non-production time such as manual replacement and adjustment, greatly improves welding capacity per unit time, and is suitable for mass production needs.

[0006] 4. Reduce labor intensity and risks: Automatic welding reduces dependence on manual labor, reduces the operator's physical labor and exposure to harmful environments such as welding smoke and arc light, and improves the safety of the working environment.

[0007] 5. Flexibility and programmability: Modern welding robots and control systems are highly flexible and can adjust welding parameters and paths according to different bucket sizes and material properties to meet diverse production needs.

[0008] Application principle: 1. Preparation before welding: First, position and fix the bucket to ensure the stability of the bucket during welding. At the same time, select appropriate welding materials (such as welding wire) and protective gas according to the material and thickness of the bucket.

[0009] 2. Programming and path setting: Program the welding robot on the computer to set the welding start point, end point, path and welding parameters. For complex bucket structures, segmented programming or multi-angle welding strategies may be required.

[0010] 3. Automatic execution: After starting the welding robot, it will automatically perform welding according to the preset program, including layer-by-layer surfacing of the bucket body, seam welding, etc. During the process, the robot can automatically adjust the welding posture to ensure the welding quality.

[0011] 4. Quality monitoring and feedback: Some high-end welding systems are equipped with welding quality monitoring devices, such as vision systems, sensors, etc., which can monitor the welding process in real time and make timely adjustments to avoid defects or optimize parameters in subsequent batches.

[0012] 5. Post-processing: After welding is completed, the bucket body is subjected to necessary post-processing, such as grinding, flaw detection, etc., to ensure that the quality of the final product meets the standards.

[0013] At present, each asphalt station and dry powder station in the mixing station is equipped with at least three bucket elevators, and each bucket elevator uses more than 100 buckets. One device is equipped with a relatively large number of buckets, manual welding takes a long time, and the weld quality is uncontrollable. In addition, the positioner of the automatic welding station is a single bucket body station. A group of positioners and welding robots corresponds to one bucket elevator bucket body, which also has low work efficiency, cannot weld the inside and outside of the bucket body evenly, and has a low welding rate.

[0014] Therefore, it is urgent to design a special tooling for double-station automatic welding of bucket elevator bucket body to solve the problems of low welding efficiency and low welding rate of single-station automatic welding of bucket elevator bucket body. Utility Model Content

[0029] like Figure 1-Figure 2 As shown, a special tooling for double-station automatic welding of bucket elevator bucket body comprises a positioner 1, a rotating disk 2, a mounting platform 3 and bucket elevator bucket body 6. The positioner 1 adopts a four-axis rotating disc-shaped welding positioner commonly used in industry to cooperate with a robot welder.

[0030] A rotating disk 2 is provided at the output end of the positioner 1, on which a mounting platform 3 is mounted, on which two bucket body stations are provided, on which bucket bodies 6 of bucket elevators are mounted, and the positioner 1 controls the rotating disk 2 to rotate to cooperate with the robot welder to weld the bucket body 6 of the bucket elevator.
