Description

Technical Field

[0001] This utility model relates to a tooling, specifically a robotic automatic welding tooling. Background Technology

[0002] With the continuous development of the manufacturing industry, the requirements for welding quality, efficiency, and consistency are becoming increasingly stringent. Traditional manual welding is insufficient to meet the demands of large-scale, high-quality production, resulting in problems such as unstable welding quality, high labor intensity, and low production efficiency. In automobile manufacturing and machining, a large amount of welding work requires efficient and precise completion, which has driven the development of welding technology towards automation and intelligence. Therefore, robotic automatic welding equipment is widely used. The tooling used in robotic automatic welding is particularly important, serving to support, position, and fix the welded parts. However, current welding tooling is insufficient for effectively positioning and fixing welded products composed of columnar and plate shapes, leading to large gaps between the two parts during welding and affecting welding quality.

Multiple vertical support plates are fixed at intervals on the surface of the base plate. The support plates and the base positioning plates are located on the same straight line, and the height of the base positioning plate is higher than that of the support plates. A semi-circular arc-shaped groove is provided on the upper edge of the support plate. A horizontal welding part positioning plate is fixed on the surface of the base plate on one side of the support plate. The welding part positioning plate is fixed to one end of a support plate, and the support plate is higher than the support plate. The end face of the cylindrical bracket product base is tightly attached to the inner wall of the base positioning plate. The cylindrical part of the bracket product is placed in the arc-shaped groove at the upper end of each support plate. The welding part is provided with a hollow positioning opening structure, which is penetrated by the welding part positioning plate. The lower surface of the welding part is placed on the support plate. Three of the edges of the welding part positioning plate are tightly attached to the three inner edges of the corresponding end of the positioning opening structure.

[0005] Furthermore, the pallet has a T-shaped structure, and the welding positioning plate is fixed at the lower end of the T-shaped part of the pallet.

[0006] Furthermore, both ends of the tray are fixed to the upper end of the vertical plate.

[0008] Furthermore, the base plate is provided with multiple mounting holes.

[0009] Furthermore, the support plate is provided with outwardly extending fixing blocks at the front and rear, and the fixing blocks on each side are fixed to the base plate by bolts.

[0010] This utility model is used in conjunction with commonly used equipment in the field, such as robotic arms, tilting tables, and MIG / MAG welding machines. After two workpieces to be welded are placed, automatic welding begins. After welding is completed, the bracket assembly is removed. The cylindrical bracket product's base end face is tightly attached to the inner wall of the base positioning plate to position the end of the bracket product. The cylindrical part of the bracket product is placed in the arc-shaped slots at the upper end of each support plate to support and fix the entire bracket product. The positioning opening structure is penetrated by the welding part positioning plate, and the lower surface of the welding part is placed on the support plate. Three edges of the welding part positioning plate are tightly attached to the three inner edges of the corresponding end of the positioning opening structure.

[0016] like Figure 1-4As shown, an automatic welding fixture for robots includes a base plate 1 and a base positioning plate 2 fixed to one end of the surface of the base plate 1. Multiple vertical support plates 3 are fixed at intervals on the surface of the base plate 1. The support plates 3 and the base positioning plate 2 are located on the same straight line, and the height of the base positioning plate 2 is higher than that of the support plates 3. A semi-circular arc-shaped groove 4 is provided on the upper edge of the support plate 3. A horizontal welding part positioning plate 5 is fixed on the surface of the base plate 1 on one side of the support plate 3. The welding part positioning plate 5 is fixed to one end of a support plate 6, and the support plate 6 is higher than the support plate 3. The base end face of a cylindrical bracket product 7 is in close contact with the inner wall of the base positioning plate 2. The cylindrical part of the bracket product 7 is placed in the arc-shaped groove 4 at the upper end of each support plate 3. The welding part 8 is provided with a hollow positioning opening structure 9. The positioning opening structure 9 is penetrated by the welding part positioning plate 5, and the lower surface of the welding part 8 is placed on the support plate 6. Three of the edges of the welding part positioning plate 5 are in close contact with the three inner edges of the corresponding end of the positioning opening structure 9.

[0017] Specifically: the support plate 6 has a T-shaped structure, and the welding positioning plate 5 is fixed at the lower end of the T-shaped part of the support plate 6. The two ends of the support plate 6 are fixed at the upper end of the vertical plate 10. There are two support plates 3, and the base plate 1 between the support plates 3 is provided with a hollow opening. The base plate 1 is provided with multiple mounting holes 11. The front and rear of the support plate 3 are respectively provided with outwardly extending fixing blocks 12. The fixing blocks 12 on each side are fixed to the base plate 1 by bolts.

[0018] The working principle of this utility model is as follows: It is used in conjunction with commonly used equipment in the field, such as robotic arms, tilting tables, and MIG / MAG welding machines. After the two workpieces to be welded are placed, i.e., the bracket product 7 is placed and the welding parts 8 are installed, the automatic welding operation begins. After welding is completed, the bracket assembly is removed. The cylindrical bracket product 7 has its base end face tightly against the inner wall of the base positioning plate 2, positioning the end of the bracket product 7. The cylindrical part of the bracket product 7 is placed in the arc-shaped slots 4 on the upper end of each support plate 3, supporting and fixing the entire bracket product 7.
