[0007] When the electromagnet is energized, it attracts the strong magnet of opposite polarity. A limit ring is fixedly sleeved on the outer wall of the movable rod. One end of the tension spring abuts against the inner wall of the outer shell, and the other end of the tension spring abuts against the outer wall of the limit ring.
[0008] The top of the housing is fixedly equipped with a controller, which is electrically connected to the power supply and the electromagnet. The shape of the card block is adapted to the shape of the tooth groove.

[0024] The adjustable robot welding fixture positioning and correction device provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in order to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments, and other alternative methods may be used by those skilled in the art; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0025] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.
[0026] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides an adjustable robot welding fixture positioning and correction device, including: a worktable 1, a bracket 2 fixedly mounted on the top of the worktable 1, an electric telescopic rod 3 fixedly mounted on the top of the bracket 2, a lifting frame 4 fixedly mounted on the output shaft of the electric telescopic rod 3, a welding gun 5 provided on the inner wall of the lifting frame 4, a first motor 6 fixedly mounted on the outer wall of the worktable 1, a lead screw 9 fixedly mounted on the output shaft of the first motor 6, and a lead screw nut sleeve 18 threadedly connected to the outer wall of the lead screw 9. The first motor 6 drives the lead screw 9 to rotate, which in turn drives the lead screw nut sleeve 18. The sleeve 18 moves linearly along the length of the lead screw 9. A movable frame 10 is fixedly mounted on the top of the lead screw nut sleeve 18. A second motor 11 is fixedly mounted on the outer wall of the movable frame 10. A gear 15 is fixedly mounted on the output shaft of the second motor 11. A turntable 16 is fixedly mounted on the outer wall of the gear 15. A fixing plate 19 is fixedly mounted on the outer wall of the turntable 16. An adjusting screw 21 is provided on the outer wall of the fixing plate 19. A clamping plate 20 is rotatably connected to one end of the adjusting screw 21 near the center point of the turntable 16. A lifting plate 12 is provided on the top of the second motor 11. The outer wall of the lifting plate 12 is open. The moving frame 10 is equipped with a toothed groove 17. A housing 13 is fixedly mounted on the top of the moving frame 10. A power supply 14 is fixedly mounted on the outer wall of the housing 13. A movable rod 23 is provided on the inner wall of the housing 13. A locking block 22 is fixedly mounted on one end of the movable rod 23 outside the housing 13, and a strong magnet 25 is fixedly mounted on the other end of the movable rod 23 inside the housing 13. An electromagnet 26 is tightly fitted to the outer wall of the strong magnet 25. A tension spring 24 is sleeved on the outer wall of the movable rod 23. The system is connected to a workbench 1, a moving frame 10, a second motor 11, a lifting plate 12, a power supply 14, and gears 15. The structure of the turntable 16 and the toothed groove 17 allows the user to adjust the angle of the workpiece to ensure the continuity of the welding surface during use. The user can raise and lower the toothed groove 17 by retracting the locking block 22, which, together with the rotation of the gear 15, causes the turntable 16 to rotate, thereby achieving the effect of adjusting the angle of the workpiece. After the adjustment is completed, the toothed groove 17 is locked by resetting the locking block 22, preventing the toothed groove 17 and the gear 15 from becoming loose during the welding process, thus improving the accuracy of the correction device when welding the workpiece.
[0027] like Figure 5 and Figure 6 As shown, when the electromagnet 26 is energized, it attracts the strong magnet 25 with opposite polarities. A limit ring is fixedly sleeved on the outer wall of the movable rod 23. One end of the tension spring 24 abuts against the inner wall of the outer shell 13, and the other end of the tension spring 24 abuts against the outer wall of the limit ring. Through the structure of the movable rod 23 and the tension spring 24, the user can move the movable rod 23 by energizing the electromagnet 26 during use, thereby changing the position of the locking block 22 and disengaging it from the tooth groove 17. Therefore, the angle adjustment operation can be completed without the user manually adjusting the position of the locking block 22, thereby improving the automation of the device and the user's work efficiency.
[0028] like Figure 5 and Figure 6 As shown, a controller is fixedly mounted on the top of the housing 13, and the controller is electrically connected to the power supply 14 and the electromagnet 26 respectively. The shape of the locking block 22 is adapted to the shape of the toothed groove 17. Through the controller and the locking block 22 structure, the controller can complete the power-on and power-off operation of the electromagnet 26, so that the user does not need to manually adjust the locking block 22, thereby achieving the effect of automated operation and improving the practicality of the device.
[0029] like Figure 4 and Figure 5 As shown, the inner wall of the tooth groove 17 meshes with the outer wall of the gear 15. The top of the moving frame 10 is provided with a short groove, and the inner wall of the short groove is slidably connected to the outer wall of the lifting plate 12. Through the structure of the gear 15 and the tooth groove 17, the gear 15 will mesh with the tooth groove 17 during the rotation process, so that the gear 15 can drive the turntable 16 to rotate when the tooth groove 17 is in the active state, thereby achieving the effect of adjusting the angle of the workpiece. When the tooth groove 17 is locked, the gear 15 cannot loosen, avoiding the workpiece from shifting position, thereby improving the welding accuracy of the workpiece by the user.
[0030] like Figure 4 and Figure 5 As shown, the movable frame 10 has a through hole on its side wall near the turntable 16, and the inner wall of the through hole is rotatably connected to the outer wall of the turntable 16. The outer wall of the fixed plate 19 has a threaded hole, and the inner wall of the threaded hole is threadedly connected to the outer wall of the adjusting screw 21. Through the structure of the clamping plate 20 and the adjusting screw 21, during the operation of the device, the user can adjust the distance between the two clamping plates 20 by adjusting the distance between the two movable frames 10 and rotating the adjusting screw 21. This allows the device to clamp and weld workpieces of different sizes, thereby improving the range of applications of the device.
[0031] like Figure 1 and Figure 2As shown, there are two movable frames 10, and both movable frames 10 are symmetrically distributed along the top of the workbench 1. By using the structure of the two movable frames 10, workpieces of different lengths can be fixed by moving the two movable frames 10, thereby ensuring that the device can perform welding operations on workpieces of different models, thus ensuring the normal use of the device and the scope of its application.
[0032] like Figures 1 to 3 As shown, the top of the worktable 1 is provided with a sliding groove 7 and a limiting groove 8. The sliding groove 7 and the limiting groove 8 are parallel to each other. The inner wall of the sliding groove 7 is slidably connected to the outer wall of the moving frame 10. The lead screw 9 is fixed in the limiting groove 8. Furthermore, the outer wall of the bottom of the outer shell of the structure to which the moving frame 10 is connected is provided with a protrusion that matches the shape of the sliding groove 7. It can slide along the path of the sliding groove 7. The protrusion is parallel to the lead screw nut sleeve 18. When the moving frame 10 moves along the lead screw 9, the limiting effect between the protrusion and the sliding groove 7 can balance the torque, so that the movement of the moving frame 10 remains stable, which is conducive to quickly and accurately adjusting the clamping state of the workpiece.
[0033] The technical solution provided by this utility model allows for the adjustment of the distance between the two movable frames 10 by the operation of the first motor 6 during operation. Then, the distance between the two clamping plates 20 is adjusted by rotating the adjusting screw 21, thereby achieving the effect of clamping workpieces of different sizes and improving the application range of the device. During the welding process, the user can rotate the gear 15 by the operation of the second motor 11. At this time, the tooth groove 17 will mesh with the gear 15 to raise and lower the lifting plate 12. After the adjustment is completed, the user can de-energize the electromagnet 26 to move the locking block 22 toward the tooth groove 17, thereby locking the lifting plate 12 and preventing the gear 15 from loosening and rotating. This avoids the workpiece from tilting or even shifting position during the welding process, thereby improving the welding accuracy of the workpiece.
[0034] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
