For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example 1: See Figure 1-Figure 5 The present invention provides a technical solution: a turning device for processing a wind turbine rotor, comprising a fixing plate 1, the top and left sides of the fixing plate 1 are fixedly connected to support rods 2, the left side of the left support rod 2 is fixedly connected to a first motor 3, the output end of the first motor 3 passes through the left support rod 2, and further comprises:

[0037] The flip mechanism 4 includes a rectangular plate 401, which is rotatably connected to the output end of the first motor 3 through a bearing, and the upper and lower ends of the rectangular plate 401 are fixedly connected to a connecting plate 402, and the output end of the first motor 3 is fixedly connected to a first sliding rod 404 on a side close to the rectangular plate 401, and a first sliding groove 405 is provided on the side of the first sliding rod 404 close to the connecting plate 402 located on the upper side, and a moving ring 407 is provided on the outer wall of the first sliding rod 404, and the moving ring 407 is slidably connected to the groove wall of the first sliding groove 405, and is provided The movable ring 407 is provided with an adjustable distance. By adjusting the distance, the movable ring 407 can be suitable for clamping and flipping more processing workpieces. Four groups of arc rods 403 are provided on the outer wall of the movable ring 407. The four groups of arc rods 403 are rotatably connected to the clamp 406 through the rotating shaft on the side away from the first motor 3. By providing four groups of arc rods 403, the workpiece can be fully clamped when entering the site. When the workpiece is flipped, the multi-position clamping can also prevent the workpiece from sliding. The flipping mechanism 4 is provided with two groups, and they are symmetrically arranged with the middle of the fixed plate 1 as the center.

[0038] The working principle of this embodiment is: when the workpiece needs to be processed, the workpiece is first placed on the load-bearing plate 603. At this time, the staff slides the movable ring 407 on the first sliding groove 405 to make the staff adjust it to the appropriate position. At this time, the staff rotates the clamp 406 to clamp it, and then the movable ring 407 slides again to lift the workpiece, so as to process the workpiece. When the workpiece needs to be flipped, the first motor 3 is started to work, and the first sliding rod 404 is driven to rotate by the first motor 3. However, the rectangular plate 401 is connected to the output end of the first motor 3 by a bearing, so the rectangular plate 401 will not rotate, so that the first sliding rod 404 is driven by the first motor 3 to rotate, thereby completing the flipping of the workpiece.

[0039] Example 2: Please refer to Figure 6-Figure 7 On the basis of the first embodiment, the present invention provides a technical solution: a shaking mechanism 5, the shaking mechanism 5 includes a curved plate 502, the bottom of the curved plate 502 is fixedly connected to the top of the connecting plate 402 located on the upper side, the middle end of the top of the curved plate 502 is fixedly connected to a second motor 501, the output end of the second motor 501 passes through the curved plate 502, and the output end of the second motor 501 is fixedly connected to a tilting rod 503. By setting the tilting rod 503, the workpiece can be rotated at a side angle, so that the workpiece can be clamped at different angles and flipped, so that multiple surfaces can be processed when processing the workpiece, thereby improving the diversification of the processing angle of the workpiece. The tilting rod 503 Four groups of connecting rods 504 are fixedly connected to the side away from the second motor 501, and the four groups of connecting rods 504 are fixedly connected to the side away from the curved plate 502. Positioning blocks 506 are provided on the side of the two groups of contact plates 505 away from the curved plate 502. The front and back sides of the positioning blocks 506 are rotatably connected to the first rotating plates 507 through a rotating shaft. Second sliding grooves 509 are provided on the sides where the two groups of first rotating plates 507 are close to each other. Sliding blocks 510 are provided on the groove walls of the two groups of second sliding grooves 509. The upper and lower ends of the sliding blocks 510 are rotatably connected to the second rotating plates 508 through a rotating shaft, and the left and right sides of the sliding blocks 510 are respectively slidably connected to the second sliding grooves 509.

[0040] The working principle of this embodiment is as follows: when the workpiece is placed on the weighing plate 603, the sliding block 510 slides in the second sliding groove 509, and the first rotating plate 507 can also be rotated angularly. The angle adjustment can achieve a wider clamping, so that the sliding block 510 slides to the side of the second sliding groove 509 away from the positioning block 506. At this time, the sliding block 510 leaks out, resulting in the second rotating plate 508 being rotated to fit with the workpiece, thereby completing the clamping of the workpiece. When the workpiece needs to be deflected at an angle, the second motor 501 is started and rotated intensively, and the second motor 501 drives the tilting rod 503 to rotate, and the tilting rod 503 drives the connecting rod 504 to rotate, resulting in the connecting rod 504 driving the contact plate 505 to deflect when rotating, and the positioning block 506 is driven to rotate by the contact plate 505 to complete the angular displacement of the workpiece.

[0041] Example 3: Please refer to Figure 8-Figure 10 On the basis of the first and second embodiments, the present invention provides a technical solution: a swing mechanism 6, the swing mechanism 6 includes a bottom plate 601, the bottom of the bottom plate 601 is fixedly connected to the top of the fixed plate 1, the top of the bottom plate 601 is fixedly connected to a rotating column 602, the side of the rotating column 602 away from the bottom plate 601 is fixedly connected to a load-bearing plate 603, the top of the load-bearing plate 603 is fixedly connected to a base 604 on both sides, and the two groups of bases 604 are fixedly connected to the side away from the load-bearing plate 603. The protective shell 606, the two sets of protective shells 606 are slidably connected to the side away from the load-bearing plate 603 with two sets of card plates 605, the bottoms of the four sets of card plates 605 are fixedly connected to the moving blocks 610, the inner walls of the four sets of moving blocks 610 are provided with rollers 613, the four sets of rollers 613 are rotatably connected through rotating columns 614, the four sets of rotating columns 614 are provided with grooves 615 on the side away from the rotating column 602, the left and right sides of the inner walls of the two sets of protective shells 606 are provided with protective shells 607, and the four sets of protective shells 607 are provided. The sides away from the moving block 610 are fixedly connected to the inner wall of the protective shell 606, the top of the inner wall of the four groups of protective shells 607 are fixedly connected to the second sliding rods 608, the bottoms of the four groups of second sliding rods 608 are fixedly connected to the bottom of the inner wall of the protective shell 607, the outer walls of the four groups of second sliding rods 608 are slidably connected to the pressing plates 611, the sides of the two groups of pressing plates 611 close to the rotating column 614 are fixedly connected to the two groups of pressing blocks 612, and the tops of the inner walls of the four groups of protective shells 607 are fixedly connected to the springs. 609. By setting the spring 609, the pressing plate 611 can be pushed, so that under the push of the spring 609, the pressing plate 611 will generate a pushing force on the lower pressing block 612, so that the lower pressing block 612 will always fit with the groove 615, to avoid the lower pressing block 612 moving out of the groove 615 when clamping the workpiece, causing the clamping plate 605 to no longer clamp the workpiece, causing the workpiece to fall off. The bottom of the four groups of springs 609 are fixedly connected to the top of the pressing plate 611.

[0042] The working principle of this embodiment is as follows: when the workpiece is placed on the weighing plate 603, the staff moves the card plate 605, and the card plate 605 is subjected to a thrust, thereby driving the moving block 610 to move, and then the moving block 610 drives the roller 613 to roll, so that the roller 613 rolls and drives the rotating column 614 to rotate synchronously. When the card plate 605 fits the workpiece, the staff presses the pressing plate 611, causing the pressing plate 611 to move downward and drive the pressing block 612 to move downward, causing the pressing block 612 to be stuck in the groove 615. At this time, the card plate 605 is also slightly moved, so that the roller 613 A small angle offset occurs, causing the lower pressure block 612 to be further fixed to the inner wall of the groove 615. At this time, the spring 609 loses its driving force, causing the spring 609 to rebound and push the pressing plate 611 to press down, so that the lower pressure block 612 is further fixed. When it is necessary to flip, the rotating column 602 is directly rotated. At this time, the workpiece will be offset and hit the clamping plate 605, resulting in an angular rotation, thereby flipping, so that the workpiece pushes the clamping plate 605 to move. When completed, the spring 609 will push the pressing plate 611, causing the lower pressure block 612 to fit with the groove 615, so that the workpiece can be clamped again.
