[0016] The present invention has the following beneficial effects:

[0017] (1) In the present invention, a steam turbine rotor body is placed on top of two support plates, and a dual-axis motor is started. The dual-axis motor drives the rotating shaft to rotate, and the rotating shaft drives the first gear to rotate. During the rotation of the first gear, the outer gear ring rotates around the fixed ring, and the outer gear ring drives the fixed rod to rotate. The fixed rod drives the annular shell to rotate, and the annular shell drives the first sliding frame to rotate. The first sliding frame drives the connecting shell to rotate, and the connecting shell drives the roller to rotate. During the rotation of the roller, the roller performs roller polishing around the recessed part of the steam turbine rotor body. Due to the elastic deformation of the spring, the spring squeezes the connecting shell, so that the connecting shell drives the roller to further fit closely with the outer wall of the recessed part of the steam turbine rotor body, thereby improving the roller polishing effect of the roller.

[0018] (2) According to the present invention, when the fixed rod rotates, the fixed rod is set by the inner gear ring frame, and the second gear is driven to rotate. The outer wall of the second gear will contact the inner wall of the inner gear ring frame, so that the second gear rotates around the outer wall of the fixed rod. The second gear drives the screw rod to rotate. The screw rod is limited by the limit rod. The threaded plate slides along the outer wall of the limit rod. The threaded plate drives the connecting plate to move. The connecting plate drives the annular member to move. The annular member drives the cross bar to move. The cross bar drives the fixed plate to move. The fixed plate drives the second sliding frame to move. The second sliding frame drives the suction cup to move. The two groups of suction cups approach each other, thereby clamping the turbine rotor body, preventing the turbine rotor body from rotating slightly when the roller wheel performs the rolling work on the turbine rotor body, thereby improving the rolling effect of the roller wheel. At the same time, when the connecting plate rotates, it drives the annular member to rotate. The notch of the annular member is limited, so that the cross bar is continuously at the bottom end of the notch inside the annular member, thereby preventing the cross bar from rotating with the annular member, thereby improving the stability of the device.

[0019] (3) In the present invention, when the threaded plate moves, the threaded plate drives the round rod to move, and the round rod drives the piston plate to move, so that the piston plate slides on the inner wall of the liquid storage ring shell. At this time, the lubricating liquid inside the liquid storage ring shell is squeezed to enter the inside of the annular shell. Due to the setting of the circular hole, the lubricating liquid enters the inside of the circular hole through the annular shell, and then the lubricating liquid is sprayed toward the outer wall of the recess of the turbine rotor body, thereby improving the rolling effect of the roller on the turbine rotor body.

[0020] (4) In the present invention, when the piston plate moves, the piston plate drives the L-shaped rod to move, and the L-shaped rod drives the elastic plate to move, and the two groups of elastic plates approach each other, and the elastic plate drives the cross bar to move, so that the cross bar can drive the first sliding frame to slide along the annular shell as a whole, and multiple first sliding frames simultaneously approach the outer wall of the recessed part of the turbine rotor body, which indirectly improves the rolling effect of the rolling wheel on the turbine rotor body, and facilitates the rolling work of the rolling wheel after the lubricating liquid is impregnated. When the rolling is completed, the dual-axis motor is started in the reverse direction to reset the threaded plate, which is convenient for rolling the next turbine rotor body.

[0041] A clamping assembly 66 is provided on the top of the bottom plate 1. When the fixing rod 652 rotates, it is set by the inner gear ring frame 661. When the fixing rod 652 drives the second gear 662 to rotate, the outer wall of the second gear 662 will contact the inner wall of the inner gear ring frame 661, so that the second gear 662 rotates around the outer wall of the fixing rod 652. The second gear 662 drives the screw rod 663 to rotate. It is limited by the limiting rod 665. The screw rod 663 drives the threaded plate 664 to slide along the outer wall of the limiting rod 665.

The clamping assembly 66 includes an inner gear ring frame 661 fixedly connected to both sides of the bottom plate 1 near the top of the fixed frame 4, and the inner wall of the inner gear ring frame 661 is respectively meshed with four second gears 662, and the inner wall of the second gear 662 is rotatably connected to the outer wall of one end of the fixed rod 652.

[0042] A screw rod 663 is fixedly connected to one side of the second gear 662, and a threaded plate 664 is threadedly connected to the outer wall of one end of the screw rod 663. Two limit rods 665 are respectively penetrated and slidably connected to one side of the threaded plate 664, and one end of the limit rod 665 is fixedly connected to the side wall of the outer gear ring 651.

[0043] The bottom of the threaded plate 664 is fixedly connected to a connecting plate 666, one end of the connecting plate 666 is fixedly connected to a ring member 667, and a cross bar 668 is slidably connected to one side of the inner wall of the ring member 667. When the connecting plate 666 rotates, the ring member 667 is driven to rotate, and the cross bar 668 is limited by the groove of the ring member 667 so that the cross bar 668 is continuously at the bottom end of the groove inside the ring member 667, preventing the cross bar 668 from rotating with the ring member 667, thereby improving the working stability of the device. One end of the cross bar 668 passes through the support plate 2 and extends to the outside of the support plate 2, and the end of the cross bar 668 away from the ring member 667 is fixedly connected to a fixing plate 669.

[0045] In Example 2, injection assemblies 67 are respectively provided on both sides of the annular shell 653. When the threaded plate 664 moves, the threaded plate 664 drives the round rod 672 to move, and the round rod 672 drives the piston plate 673 to move, so that the piston plate 673 slides on the inner wall of the liquid storage annular shell 671. At this time, the lubricating liquid inside the liquid storage annular shell 671 is squeezed and enters the inside of the annular shell 653. Due to the setting of the circular hole 674, the lubricating liquid enters the inside of the circular hole 674 through the annular shell 653, and then the lubricating liquid is sprayed toward the outer wall of the recessed part of the turbine rotor body 3. Working, improving the rolling effect of the rolling wheel 656 on the turbine rotor body 3, the injection assembly 67 includes a liquid storage ring shell 671 connected to the two sides of the annular shell 653, and round rods 672 are fixedly connected to both ends of one side of the threaded plate 664. One end of the round rod 672 penetrates the liquid storage ring shell 671 and extends to the interior of the liquid storage ring shell 671. The end of the round rod 672 away from the threaded plate 664 is fixedly connected to a piston plate 673. The outer wall of the piston plate 673 is slidably connected to the inner cavity of the liquid storage ring shell 671.

The multiple first sliding frames 654 simultaneously approach the outer wall of the recessed part of the turbine rotor body 3, which indirectly improves the rolling effect of the roller 656 on the turbine rotor body 3, and facilitates the rolling work of the roller 656 after the lubricating liquid is impregnated. When the rolling is completed, the dual-axis motor 62 is started in reverse to reset the threaded plate 664, which is convenient for rolling the next turbine rotor body 3. The auxiliary component 68 includes four L-shaped rods 681 fixedly connected to the piston plate 673 around the side close to the round rod 672. One end of the L-shaped rod 681 penetrates the liquid storage ring shell 671 and extends to the outside of the liquid storage ring shell 671.

The dual-axis motor 62 drives the rotating shaft 63 to rotate, and the rotating shaft 63 drives the first gear 64 to rotate. During the rotation of the first gear 64, the outer gear ring 651 rotates around the fixed ring 5, and the outer gear ring 651 drives the fixed rod 652 to rotate, and the fixed rod 652 drives the annular shell 653 to rotate, and the annular shell 653 drives the first sliding frame 654 to rotate, and the first sliding frame 654 drives the connecting shell 655 to rotate, and the connecting shell 655 drives the roller 656 to rotate. During the rotation of the roller 656, the roller will perform roller work around the recessed part of the steam turbine rotor body 3, and the spring 657 is elastically deformed. The spring 657 squeezes the connecting shell 655, so that the connecting shell 655 drives the roller 656 to further fit closely with the outer wall of the recessed part of the steam turbine rotor body 3, thereby improving the roller effect of the roller 656.

The fixed plate 669 drives the second sliding frame 6610 to move, and the second sliding frame 6610 drives the suction cup 6612 to move, and the two groups of suction cups 6612 approach each other, so as to clamp the turbine rotor body 3 to prevent the turbine rotor body 3 from rotating slightly when the roller 656 performs the rolling work on the turbine rotor body 3, thereby improving the rolling effect of the roller 656. At the same time, when the connecting plate 666 rotates, it will drive the annular member 667 to rotate, and the notch of the annular member 667 will limit the cross bar 668 to continuously be at the bottom end of the notch inside the annular member 667, thereby preventing the cross bar 668 from rotating with the annular member 667, thereby improving the stability of the device.

[0049] When the threaded plate 664 moves, the threaded plate 664 drives the round rod 672 to move, and the round rod 672 drives the piston plate 673 to move, so that the piston plate 673 slides on the inner wall of the liquid storage ring shell 671. At this time, the lubricating liquid inside the liquid storage ring shell 671 is squeezed and enters the inside of the annular shell 653. Due to the setting of the circular hole 674, the lubricating liquid enters the inside of the circular hole 674 through the annular shell 653, and then the lubricating liquid is sprayed toward the outer wall of the recess of the turbine rotor body 3, thereby improving the rolling effect of the roller 656 on the turbine rotor body 3.

[0050] When the piston plate 673 moves, the piston plate 673 drives the L-shaped rod 681 to move, and the L-shaped rod 681 drives the elastic plate 682 to move, and the two groups of elastic plates 682 approach each other, and the elastic plate 682 drives the cross bar 683 to move, so that the cross bar 683 can drive the first sliding frame 654 to slide along the annular shell 653 as a whole, and multiple first sliding frames 654 approach the outer wall of the recessed part of the turbine rotor body 3 at the same time, which indirectly improves the rolling effect of the rolling wheel 656 on the turbine rotor body 3, and facilitates the rolling work of the rolling wheel 656 after the lubricating liquid is impregnated. When the rolling is completed, the dual-axis motor 62 is started in reverse to reset the threaded plate 664, which is convenient for the rolling work of the next turbine rotor body 3.
