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.

[0014] In the existing technology, the bucket connecting seat often undergoes significant deformation after welding, manifested as warping on the left and right sides or in the middle. At the same time, the dimensions, plate thickness, and weld leg dimensions of various specifications of bucket connecting seats are different, making it impossible to adjust the amount of deformation according to requirements, which affects the welding quality of the bucket and the adaptability of the welding positioner.

Through the cooperation of the positioner base, tilting seat, slewing support seat, horizontal adjustment seat, support block, anti-deformation amount adjustment bolt, first anti-deformation clamping block, first hydraulic cylinder, fixed seat, second anti-deformation clamping block, second hydraulic cylinder, and support plate, the anti-deformation of the bucket connecting seat is adjusted by top clamping at the middle and sides of the bucket connecting seat and by rotating and adjusting the support height of the anti-deformation amount adjustment bolt at the bottom sides of the bucket connecting seat. This counteracts welding deformation, improves the welding production efficiency and welding quality of the bucket connecting seat, and allows for adaptive adjustment of the anti-deformation amount according to different dimensions and plate thicknesses of the bucket connecting seat, improving the compatibility and utilization rate of the equipment.

[0016] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0017] Depend on Figure 1-5 It is known that a welding positioner for an excavator connecting seat with adjustable anti-deformation includes a positioner base 1, a tilting seat 2 inside the positioner base 1, a slewing support seat 3 on the top of the tilting seat 2, and horizontal adjustment seats 4 on both sides of the top of the slewing support seat 3. A support block 5 is fixedly connected to one side of the horizontal adjustment seat 4, and an anti-deformation adjustment bolt 6 is threadedly connected to the top of the support block 5. A first hydraulic cylinder 8 is fixedly connected at equal intervals to the side of the horizontal adjustment seat 4 near the support block 5. A first anti-deformation clamping block 7 is rotatably connected to the output end of the first hydraulic cylinder 8. The deformable clamping block 7 is rotatably connected to the horizontal adjusting seat 4. A fixed seat 9 is provided on one side of the two horizontal adjusting seats 4 that are close to each other. The fixed seat 9 is fixedly connected to the rotary support seat 3. The top of the fixed seat 9 is rotatably connected to the side of the first hydraulic cylinder 8. The fixed seat 9 is rotatably connected to the second hydraulic cylinder 11 below the second anti-deformation clamping block 10. The output end of the second hydraulic cylinder 11 is rotatably connected to the second anti-deformation clamping block 10. The rotary support seat 3 is fixedly connected to the support plates 19 on both sides of the fixed seat 9 and the top of the horizontal adjusting seat 4 respectively. In the specific implementation process, it is worth noting that, through the cooperation between the positioner base 1, the tilting seat 2, and the slewing support seat 3, a servo motor driving the tilting seat 2 to tilt is installed on one side of the positioner base 1, and a servo motor driving the slewing support seat 3 to rotate is installed at the bottom of the tilting seat 2. This allows for multi-angle rotation adjustment of the slewing support seat 3 to meet welding requirements at different angles. Furthermore, through the cooperation between the slewing support seat 3 and the horizontal adjustment seat 4, two horizontal adjustment seats 4 are provided. These seats are fixed to the bucket connecting seat by clamping and fixing components and can be moved and adjusted in opposite directions, thereby adapting to... For bucket connecting seats of different sizes, the adjustment mechanism utilizes the cooperation of the slewing support 3, the horizontal adjustment seat 4, the support block 5, the anti-deformation adjustment bolt 6, the first anti-deformation clamping block 7, and the first hydraulic cylinder 8. The anti-deformation adjustment bolt 6 provides support on both sides of the bottom of the bucket connecting seat. By controlling the first hydraulic cylinder 8, the first anti-deformation clamping block 7 is driven to rotate, pressing it against both sides of the top of the bucket connecting seat. Rotating the anti-deformation adjustment bolt 6 allows for adjustment of its support height, thereby achieving vertical adjustment of the bucket connecting seat. Anti-deformation adjustment effectively avoids deformation caused during welding, ensuring the dimensional accuracy of the bucket connecting seat after welding. Through the cooperation between the rotary support seat 3, fixed seat 9, second anti-deformation clamping block 10, second hydraulic cylinder 11, and support plate 19, the top surfaces of the fixed seat 9 and support plate 19 are at the same height, supporting the bottom of the bucket connecting seat. By controlling the second hydraulic cylinder 11, the second anti-deformation clamping block 10 is driven to rotate, thereby clamping the middle of the bucket connecting seat. Through the positioner base 1, tilting seat 2, rotary support seat 3, horizontal adjustment seat 4, support block 5, and anti-deformation adjustment... The cooperation between the joint bolt 6, the first anti-deformation clamping block 7, the first hydraulic cylinder 8, the fixed seat 9, the second anti-deformation clamping block 10, the second hydraulic cylinder 11, and the support plate 19 achieves anti-deformation adjustment of the bucket connecting seat by top clamping at the middle and both sides of the bucket connecting seat and adjusting the support height of the anti-deformation adjustment bolt 6 by rotating it on both sides of the bottom of the bucket connecting seat. This counteracts welding deformation, improves the welding production efficiency and welding quality of the bucket connecting seat, and allows for adaptive adjustment of the anti-deformation amount according to different sizes and plate thicknesses of the bucket connecting seat, thereby improving the compatibility and utilization rate of the equipment. Furthermore, an X-axis limiting rail 12 is fixedly connected to the top of the horizontal adjusting seat 4 near the fixed seat 9, and a third hydraulic cylinder 13 is fixedly connected to the top of the horizontal adjusting seat 4 away from the X-axis limiting rail 12. An X-axis clamping block 14 is slidably connected to the inner wall of the X-axis limiting rail 12, and the X-axis clamping block 14 is fixedly connected to the output end of the third hydraulic cylinder 13. An X-axis limiting block 15 is fixedly connected to the side of the horizontal adjusting seat 4 where the two first anti-deformation pressing blocks 7 are close to each other. The X-axis limiting block 15 limits the range of movement of the bucket connecting seat in the X-axis direction. To ensure the accuracy of the fixed position of the bucket connecting seat, a Y-direction limiting rail 16 is fixedly connected to the top of the horizontal adjusting seat 4 on the side away from the fixed seat 9. A fourth hydraulic cylinder 17 is fixedly connected to the horizontal adjusting seat 4 on the side of the Y-direction limiting rail 16 away from the fixed seat 9. A Y-direction clamping block 18 is slidably connected to the inner wall of the Y-direction limiting rail 16. The Y-direction clamping block 18 has a downward slope on the side away from the fourth hydraulic cylinder 17 to ensure the clamping stability of the bucket connecting seat. The Y-direction clamping block 18 is fixedly connected to the output end of the fourth hydraulic cylinder 17. In the specific implementation process, it is worth noting that the X-axis limiting block 15 restricts the range of movement of the bucket connecting seat in the X-axis direction, ensuring the accuracy of the fixed position of the bucket connecting seat. Through the cooperation between the horizontal adjusting seat 4, the X-axis limiting rail 12, the third hydraulic cylinder 13, the X-axis clamping block 14, and the X-axis limiting block 15, the third hydraulic cylinder 13 is controlled to drive the X-axis clamping block 14 to slide within the X-axis limiting rail 12. After the connecting seats are abutted together, the X-axis clamping block 14 and the X-axis limiting block 15 effectively clamp and position the bucket connecting seat in the X-axis direction. The Y-axis clamping block 18 has a downward slope on the side away from the fourth hydraulic cylinder 17 to ensure the clamping stability of the bucket connecting seat. Through the cooperation between the horizontal adjusting seat 4, the Y-axis limiting rail 16, the fourth hydraulic cylinder 17 and the Y-axis clamping block 18, the fourth hydraulic cylinder 17 is controlled to drive the Y-axis clamping block 18 to move within the Y-axis limiting rail 16. The sliding mechanism, after the Y-axis clamping block 18 abuts against both sides of the bucket connecting seat, effectively clamps and positions the bucket connecting seat in the Y-axis direction. The clamping and fixing structure of the bucket connecting seat is formed by the cooperation between the horizontal adjusting seat 4, the X-axis limiting rail 12, the third hydraulic cylinder 13, the X-axis clamping block 14, the X-axis limiting block 15, the Y-axis limiting rail 16, the fourth hydraulic cylinder 17, and the Y-axis clamping block 18. By controlling the third hydraulic cylinder 13 and the fourth hydraulic cylinder 17, the X-axis clamping block 14 and the Y-axis clamping block 18 are driven to move respectively, achieving clamping and positioning of the bucket connecting seat on the X and Y axes. This clamps and fixes the bucket connecting seat at the top of the positioner, further ensuring the stability of the workpiece during welding and adapting to bucket connecting seats of different sizes, improving the positioner's adaptability to bucket connecting seats of different sizes. The specific models of the third hydraulic cylinder 13 and the fourth hydraulic cylinder 17 are not limited, as long as they meet the usage requirements. Furthermore, slide rails 20 are fixedly connected to both sides of the top of the rotary support 3, and the horizontal adjustment seat 4 is slidably connected to the slide rails 20. The rotary support 3 is rotatably connected to the horizontal adjustment seat 4 below the horizontal adjustment seat 21. The double-threaded screw 21 is threadedly connected to the horizontal adjustment seat 4. A hydraulic motor 22 is fixedly connected to one end of the double-threaded screw 21 on the rotary support 3. The output end of the hydraulic motor 22 is connected to the double-threaded screw 21 for transmission. In the specific implementation process, it is worth noting that through the cooperation between the slewing support 3, the horizontal adjustment seat 4, the slide rail 20, the double-sided threaded screw 21 and the hydraulic motor 22, the hydraulic motor 22 is controlled to drive the double-sided threaded screw 21 to rotate, thereby causing the two horizontal adjustment seats 4 to move towards each other on the slide rail 20, thereby adjusting the distance between the two horizontal adjustment seats 4, and thus enabling the positioner to adapt to bucket connection seats of different sizes, improving the processing adaptability of the positioner. The specific model of the hydraulic motor 22 is not limited, as long as it meets the usage requirements. Furthermore, a first laser rangefinder 23 is fixedly connected to the outer wall of the support plate 19 located at the top of the horizontal adjustment seat 4, and a second laser rangefinder 24 is fixedly connected to the side of the fixed seat 9 near the second anti-deformation pressing block 10. In the specific implementation process, it is worth noting that the first laser ranging sensor 23 and the second laser ranging sensor 24 respectively sense the distance between the bucket connecting seat and the bottom center and both sides of the bucket connecting seat, and transmit the sensing signals to the positioner control system in real time. By comparing the data parameters at each position, the control system can accurately judge the slight deformation of the bucket connecting seat during the fixing and welding process, and thus adjust the welding parameters or the amount of deformation in a timely manner to ensure welding quality and accuracy. The specific models of the first laser ranging sensor 23 and the second laser ranging sensor 24 are not limited, as long as they meet the usage requirements. Furthermore, a pressure sensor 25 is provided on the fixing seat 9 below the second anti-deformation clamping block 10; In the specific implementation process, it is worth noting that the pressure sensor 25 is used to sense the pressure applied to the workpiece by the second anti-deformation clamping block 10 and transmit the sensing signal to the control system of the positioner in real time, thereby realizing precise control of the workpiece clamping force and monitoring the fixed state of the bucket connecting seat during the welding process. The specific model of the pressure sensor 25 is not limited, as long as it meets the usage requirements.
