Description

Technical Field

[0001] The invention relates to a welding device, in particular to a flip welding tool and a welding device. Background Art

[0002] In the scarifier manufacturing industry, traditional welding processes have many significant defects when processing their workpieces. Scarifier workpieces usually have complex shapes and structures, such as the curved surfaces, edges and corners of their key components, and internal reinforcement ribs, which bring great challenges to welding. Traditional welding mainly relies on manual handheld welding tools for operation. When welding these complex parts, it is difficult to accurately control the welding angle, speed and heat input, resulting in drastic fluctuations in weld quality; problems such as uneven welds, slag inclusions, and pores often occur, which seriously weaken the strength and sealing of welded joints and reduce the reliability and service life of scarifiers under harsh working conditions; in terms of tooling adaptability, the existing welding technology lacks special For the effective positioning tooling of the ripper welded parts, the traditional general tooling is difficult to meet the precise positioning requirements of the ripper workpieces due to the significant size differences and structural diversity between different models. These general tooling usually only have simple fixing or rough manual adjustment methods, and cannot be targeted and firmly clamped and accurately positioned according to the unique shape and size of the ripper welded parts. In actual operation, the operator has to rely on experience and multiple attempts to place the welded parts, which makes the welded parts unstable in the initial stage of welding. During the welding process, due to the lack of reliable positioning constraints, the welded parts are prone to displacement and shaking, which seriously interferes with the stability of the welding arc and the forming process of the welding pool. This unstable condition directly leads to a significant decrease in welding accuracy, and the welds are prone to defects such as deviation and distortion, which makes it difficult to ensure the welding quality and significantly increases the scrap rate. At the same time, due to repeated adjustments and reprocessing after welding failures, the production cost and production cycle are greatly increased, which seriously restricts the production efficiency and product quality improvement of the ripper. With the rapid development of agricultural mechanization, the market demand for tillers continues to grow, and the requirements for their production efficiency and quality are also increasing. However, the traditional welding process has a low degree of automation, making it difficult to achieve automatic flipping and precise position adjustment of workpieces. It relies heavily on manual operation and cannot meet the needs of large-scale production. Under the pressure of efficient production, the limitations of traditional welding processes have become increasingly prominent, becoming a key factor restricting the development of the tiller manufacturing industry. There is an urgent need for a new type of welding tooling and device that can effectively solve the above problems, so as to improve the welding process level and production efficiency of tiller manufacturing and ensure the stability and reliability of product quality.

[0040] Two guide rails 60 are provided at the upper end of the positioning seat 36, and the feed plate 38 is slidably connected to the positioning seat 36 through the guide rails 60. There is a mounting groove 61 opened at the upper end of the positioning seat 36 between the two guide rails 60, and the propulsion cylinder 39 is arranged in the mounting groove 61.

[0041] It also includes a support unit 62, the support unit 62 includes two support boxes 63, each of the support boxes 63 is located between the feeding installation unit 31 and the welding unit 30; A box door 65 is provided on the outside of each of the support boxes 63, and a limiting column 66 for limiting the support box body 7 is provided on the outer side of the upper end of each of the support boxes 63. A support guide roller 67 is rotatably provided between the two support boxes 63, and a support guide roller guide groove 68 is opened at the lower end of the feed plate 38. Each of the support guide rollers 67 is located at the support guide roller guide groove 68 and is fitted with the lower end of the feed plate 38 for supporting the feed plate 38.

[0042] Working principle of flip welding tooling 1. Clamping and rotation of welded parts: The rotating parts 2 arranged in the upper half of the two symmetrical supporting and positioning bodies 1 are used to clamp and position the welding parts 3. The driving unit is not marked in detail in the figure (it is a servo motor in the prior art). When the driving unit is started, the power generated by it is transmitted to the rotating parts 2, causing the rotating parts 2 to rotate around the axis, thereby driving the clamped welding parts 3 to flip over. In this way, during the welding process, all-round welding can be achieved by rotating the welding parts 3, ensuring the uniformity and integrity of the welding and meeting the requirements of complex welding processes.

[0043] 2. Tooling adjustment mechanism The adjustment base 5 and the positioning base 6 respectively support the positioning body 1, and the guide seat 8 at the lower end of the adjustment base 5 extends into the box through the adjustment port 9 at the upper end of the support box 7, and is connected to the adjustment mechanism 10. The adjustment seat 11 in the adjustment mechanism 10 is slidably connected to the inner wall of the support box 7, the lower end of the guide seat 8 is connected to the upper end of the adjustment seat 11, the rack 12 at the lower end of the adjustment seat 11 is meshed with the gear 13, and the gear 13 is sleeved on the rotating shaft 15, the rotating shaft 15 passes through the support box 7 and is provided with a connecting groove 16 at one end for connecting the output end of the power source (the power source can be a motor or a hand-held rotating handle, which is selected according to actual use requirements). When the power source drives the rotating shaft 15 to rotate, the gear 13 rotates and drives the rack 12 to move, so that the adjustment seat 11 moves along the length direction of the supporting box 7, thereby realizing the position adjustment of the adjustment base 5 to adapt to the installation requirements of welding parts 3 of different sizes. Before clamping, the distance between the adjustment base 5 and the positioning base 6 is pulled apart so that the welding part 3 can be placed between the adjustment base 5 and the positioning base 6, and then the adjustment base 5 is driven to move to shorten the distance between the adjustment base 5 and the positioning base 6, thereby completing the clamping action.

[0044] The movable tooth 17 matched with the gear 13 has its upper end connected to the lower end of the adjustment seat 11 in a sliding connection. Under the coordinated operation of the positioning rod 19, the first support 18, the second support 20 and the return spring 22, when the gear 13 is in a normal rotation state, the movable tooth 17 is closely matched with the rack 12, thereby driving the adjustment base 5 to move. Once the gear 13 contacts the movable tooth 17, the adjustment base 5 and the positioning base 6 can just firmly clamp the weldment 3, and even if the gear 13 continues to rotate, it can no longer push the rack 12 to move. When the gear 13 rotates further, the force it exerts will cause the movable tooth 17 to move in the direction of the rack 12. Since the movable tooth 17 is at the edge of the rack 12, the gear 13 can only contact the movable tooth 17 at this time. After the movable tooth 17 moves in the direction of the rack 12 due to the force of the gear 13, the return spring 22 will quickly play a role to reset it. This ingenious design constitutes a safety protection mechanism, which effectively ensures that even if the gear 13 continues to rotate after the adjusting base 5 and the positioning base 6 have completed the clamping operation on the weldment 3, the distance between the adjusting base 5 and the positioning base 6 will not be further reduced, thereby ensuring the stability and safety of the entire device during operation, providing a reliable guarantee for the smooth progress of welding work, and also laying a solid foundation for the efficient and stable operation of the device, helping the welding device to move forward steadily on the road of high-end and intelligent development.

[0045] The supporting box 7 includes a box 23 and a top plate 26. The guide wheel grooves 27 provided on the box 23 and the top plate 26 respectively cooperate with the upper limit guide wheel 28 at the lower end of the adjusting base 5 and the lower limit guide wheel 29 at the upper end of the adjusting seat 11. During the adjustment process, the upper limit guide wheel 28 and the lower limit guide wheel 29 slide in the guide wheel grooves 27 to play a guiding and limiting role, thereby ensuring the smooth movement of the adjusting base 5 and the adjusting seat 11, preventing deviation and shaking, and further improving the reliability and accuracy of the tooling.

[0046] Working principle of welding device 1. Welding operation: A welding robot arm 33 is provided on the mounting base 32 of the welding unit 30, and a welding gun head 35 at the front end of the robot arm is detachable and replaceable. During welding, a suitable welding gun head 35 is selected according to the welding process and the material of the welded part 3, and the welding robot arm 33 moves the welding gun head 35 to the welded part 3 according to a preset program or manual control by an operator, and starts the welding power supply, and the welding gun head 35 generates a welding arc or heat, so that the welding material is melted and filled in the welding joint to achieve a welding connection.

[0047] 2. Support box feeding and positioning The supporting feet 37 at the lower ends of the positioning seats 36 of the two feeding installation units 31 provide stable support, clamping the welding piece 3 between the adjusting base 5 and the positioning base 6. When the clamping process is performed, the supporting box 7 is away from the welding unit 30. After the clamping is completed, the two feeding installation units 31 are started at the same time. Specifically, the feeding plate 38 is moved toward the welding unit 30 by cooperating with the thrust cylinder 39 and the motor in the power box 56, so that the welding piece 3 above the supporting box 7 is moved to the welding unit 30 for welding. The first sprocket 50 and the second sprocket 51 on the feeding plate 38, the third sprocket 52 on the positioning seat 36, the fourth sprocket 55 on the heightening seat 53 and the fifth sprocket 57 driven by the motor in the power box 56 are connected by a driving chain 59 to form a transmission system, which ensures the feeding position accuracy of the supporting box 7, meets the different requirements of welding operations, and improves the degree of automation and stability of the welding process.

[0048] When the motor in the power box 56 at the lower end of the positioning seat 36 drives the fifth sprocket 57 to rotate, the tensioning adjustment wheel 58 can adjust the tightness of the chain 59 to ensure that the chain 59 always maintains appropriate tension under different working conditions, prevents the chain 59 from falling off or slipping, ensures the reliability and stability of the transmission system, and maintains the normal operation of the feed installation unit 31.

[0049] Support unit auxiliary function: The two support boxes 63 of the support unit 62 are located between the feed installation unit 31 and the welding unit 30. The box door 65 on the outside of the support box 63 facilitates the maintenance of the internal components, and the limit column 66 on the outside of the upper end is used to limit the support box 7 to prevent it from exceeding the specified range during movement. The support guide roller 67 between the two support boxes 63 cooperates with the support guide roller guide groove 68 at the lower end of the feed plate 38. When the feed plate 38 moves, the support guide roller 67 provides support and guidance for the feed plate 38, reduces the risk of deformation caused by force on the feed plate 38, ensures the movement stability and straightness of the feed plate 38, and thus improves the working accuracy and stability of the entire welding device.
