[0028] It is worth mentioning that when the operator needs to process the waste hole of the turbine casing, he first loosens the limit bolt 26, and then drives the third screw 18 to rotate by adjusting the first adjusting knob 9. When the third screw 18 rotates, it drives the adjusting block 21 to move forward and backward, and pushes the movable plate 24 to swing in an arc shape forward and backward through the adjusting block 21. When the movable plate 24 swings back and forth, it drives the adjusting platform 2 to tilt and tightens the limit bolt 26 to fix it, thereby adjusting the angle of the adjusting plate, and also making it convenient for the operator to process the waste hole of the turbine casing.

[0029] Furthermore, a motor box 6 is fixedly connected to the bottom of the inner wall of the adjusting platform 2, a double-headed motor 7 is fixedly connected to the bottom of the inner wall of the motor box 6, the output shafts on both sides of the double-headed motor 7 are fixedly connected to the first screw rods 8, the ends of the two first screw rods 8 are respectively rotatably connected to the fixed axes on both sides of the inner wall of the adjusting platform 2, the outer surfaces of the two first screw rods 8 are threadedly sleeved with T-shaped moving blocks 3, and the two sides of the motor box 6 are fixedly connected to limit rods, and the ends of the two limit rods respectively penetrate the two T-shaped moving blocks 3 and are fixedly connected to the two sides of the inner wall of the adjusting platform 2.

The inner side of each group of fixed plates 17 is connected to the second screw rod 12 by fixed axis rotation. The two second screw rods 12 respectively penetrate one side of the two groups of fixed plates 17 and are fixedly connected to the second adjusting button 16. The outer surfaces of the two second screw rods 12 are threadedly sleeved with I-shaped moving blocks 30.

When the clamping plate 11 clamps the two sides of the turbine shell to a certain extent, the I-shaped moving block 30 is driven to move forward and backward by adjusting the second adjusting button 16. When the I-shaped moving block 30 moves, it drives the movable rod 33 to move and pushes the clamping plate 11 to rotate with the rotating rod 15 as the rotation center, and then the relative clamp between the two clamping plates 11 is adjusted, so that the telescopic rods 4 arranged on the two clamping plates 11 can better contact and abut against the outer wall of the turbine shell, so that the clamping plate 11 can clamp and fix turbine shells of various shapes and sizes.

[0032] Working principle: First, the staff places the turbine shell to be processed on the processing table 5, and then starts the double-headed motor 7 to drive the first screw 8 to rotate. When the first screw 8 rotates, it drives the T-shaped moving block 3 to move left and right, so that the clamping plate 11 set on the T-shaped moving block 3 clamps the two sides of the turbine shell.

[0033] When the clamping plate 11 clamps the two sides of the turbine shell to a certain extent, the I-shaped moving block 30 is driven to move forward and backward by adjusting the second adjusting button 16. When the I-shaped moving block 30 moves, it drives the movable rod 33 to move and pushes the clamping plate 11 to rotate with the rotating rod 15 as the rotation center, and then the relative clamps between the two clamping plates 11 are adjusted, so that the telescopic rods 4 set on the two clamping plates 11 can better contact and abut against the outer wall of the turbine shell, so that the clamping plate 11 can clamp and fix turbine shells of various shapes and sizes.

[0034] Then the operator loosens the limit bolt 26, and then drives the third screw 18 to rotate by adjusting the first adjusting knob 9. When the third screw 18 rotates, it drives the adjusting block 21 to move forward and backward, and pushes the movable plate 24 to swing in an arc shape forward and backward through the adjusting block 21. When the movable plate 24 swings forward and backward, it drives the adjusting platform 2 to tilt and tightens the limit bolt 26 to fix it, thereby adjusting the angle of the adjusting plate. At the same time, it is also convenient for the operator to process the waste hole of the turbine casing.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
