Description

Technical Field

[0001] This utility model relates to the field of positioner technology, specifically to a positioner for workpiece flipping based on welding. Background Technology

[0002] Workpiece welding is a manufacturing process that permanently joins two or more metal workpieces together. During the welding process, the workpieces are usually flipped using a positioner to meet different welding positions.

[0003] In existing technologies, welding flipping positioners basically fix the workpiece with two clamping members and use two flipping mechanisms fixed on the two clamping members to flip the workpiece to be welded. However, most positioners are installed in a fixed position during use, which is not convenient to move the position according to the actual welding requirements of the workpiece. This can easily lead to the robot's robotic arm being too short to weld, thus affecting the final welding effect on the workpiece. Utility Model Content

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] Please see Figures 1 to 4 A workpiece flipping positioner based on welding includes a base frame 1, a positioner stage 2, a moving assembly, a positioner frame 3, a positioner assembly, support cylinders 4, a driven frame 5, a driving frame 6, a clamping assembly, and a stabilizing assembly. Two base frames 1 are provided. The positioner stage 2 is movably positioned on top of the base frame 1. The moving assembly is positioned between the positioner stage 2 and the two base frames 1. The positioner frame 3 is rotatably positioned on top of the positioner stage 2. The positioner assembly is positioned between the positioner frame 3 and the positioner stage 2. Two support cylinders 4 are provided. 4 are symmetrically connected to the displacement frame 3, the driven frame 5 is fixedly connected to each support cylinder 4, the active frame 6 is slidably set on each support cylinder 4, and two limiting blocks 22 are symmetrically connected on the active frame 6. The support cylinder 4 is provided with a limiting groove for the limiting blocks 22 to slide, so as to limit the sliding of the active frame 6 on the support cylinder 4 and make the active frame 6 move stably in the support cylinder 4. The clamping component is set between the two active frames 6, and the stabilizing component is set between the two active frames 6 and the two driven frames 5.

[0051] Specifically, the displacement assembly includes a motor 7, a rotating frame 8, a connecting frame 9, and a rotating rod 10. The motor 7 is installed on the top of the displacement platform 2. The rotating frame 8 is fixedly connected to the output end of the motor 7. The connecting frame 9 is fixedly connected between the displacement frame 3 and the connecting frame 9. Multiple rotating rods 10 are provided, and each of the multiple rotating rods 10 is fixedly connected to the bottom end of the rotating frame 8 and the connecting frame 9. The displacement platform 2 is provided with grooves for the multiple rotating rods 10 to rotate. By rotating the rotating rods 10 in the grooves, the stability of the rotating frame 8 rotating on the upper side of the displacement platform 2 can be increased.

[0052] After the workpiece to be welded is clamped, the motor 7 is started, which drives the rotating frame 8 to rotate, so that the rotating frame 8 can drive the connecting frame 9, the displacement frame 3, the driving frame 6 and the driven frame 5 to rotate, thereby allowing the workpiece to be welded to be flipped.

[0053] Specifically, the moving assembly includes a mounting plate 11, a mounting frame, a first electric cylinder 12, and a moving plate 13. The mounting plate 11 is fixedly connected between two base frames 1, and the mounting frame is fixedly connected to one side of the mounting plate 11. The first electric cylinder 12 is mounted on the mounting frame, and the output end of the first electric cylinder 12 is connected through the mounting plate 11. The moving plate 13 is fixedly connected between the output end of the first electric cylinder 12 and the positioner 2. Two sliding plates 23 are symmetrically connected to the bottom end of the positioner 2. Both base frames 1 are provided with sliding grooves for the sliding plates 23 to slide, so that the positioner 2 can move smoothly between the two base frames 1.

[0054] When it is necessary to adjust the welding position horizontally, the first electric cylinder 12 is activated, which pushes the moving plate 13 so that the moving plate 13 can drive the positioner 2 to move, thereby moving the connecting frame 9, the positioner 3, the active frame 6 and the driven frame 5, etc., which facilitates the adjustment of the welding position of the workpiece.

[0055] Specifically, the clamping assembly includes a fixed frame 14, a second electric cylinder 15, a push block 16, and a push rod 17. The fixed frame 14 is fixedly connected to the top of the displacement frame 3. The second electric cylinder 15 is mounted on the fixed frame 14. The push block 16 is fixedly connected to the output end of the second electric cylinder 15. There are two push rods 17, which are respectively slidably disposed on the two support cylinders 4. The push rods 17 are fixedly connected to the active frame 6, and a push column 18 is fixedly connected between the two push blocks 16 and the two push rods 17.

[0056] When it is necessary to clamp the workpiece to be welded, the second electric cylinder 15 is activated, which pushes the push block 16 so that the push block 16 drives the push column 18 to move. This allows the push column 18 to drive the two push rods 17 to move simultaneously, which in turn facilitates the simultaneous movement of the two active frames 6, so that the two active frames 6 and the two driven frames 5 can stably clamp the workpiece to be welded.

[0057] Specifically, the stabilizing assembly includes a stabilizing cylinder 19, a stabilizing rod 20, and a limiting strip 21. There are two stabilizing cylinders 19, which are fixedly connected to two driven frames 5 respectively. There are two stabilizing rods 20, which are fixedly connected to two driving frames 6 respectively, and the stabilizing rods 20 are connected through the stabilizing cylinder 19. The limiting strip 21 is fixedly connected between the two stabilizing rods 20, and the stabilizing cylinder 19 has a limiting opening for the limiting strip 21 to slide.

[0058] When the two active frames 6 move simultaneously, the two stabilizer bars 20 will move within the two stabilizer cylinders 19 respectively. At the same time, the movement of the limit bar 21 within the two limit ports can make the two stabilizer bars 20 move stably at the same time, thereby making the two active frames 6 move stably at the same time, which facilitates the stable clamping and positioning of the workpiece to be welded.

[0059] In summary, this welding-based workpiece flipping positioner, after placing the workpiece to be welded between two driven frames 5, activates the second electric cylinder 15, causing it to push the push block 16 and push column 18, which in turn pushes the two push rods 17 against the two active frames 6, allowing the two active frames 6 and the two driven frames 5 to stably clamp the workpiece. Then, according to the welding requirements of the workpiece, activates the first electric cylinder 12, causing it to push the moving plate 13, which moves the positioner 2 between the two base frames 1, thereby adjusting the welding position of the workpiece. When it is necessary to flip the workpiece and adjust the weld position, activate the motor 7, causing it to drive the connecting frame 9 and the positioner 3 to rotate, which in turn rotates the support cylinder 4, the active frames 6, and the driven frames 5, allowing the active frames 6 and the driven frames 5 to flip the workpiece.
