[0014] By arranging an upper clamping seat, a lower clamping seat and a power mechanism, the turbine casing can be placed between the upper clamping seat and the lower clamping seat when the outer side of the turbine is milled and clamped. Then the driving motor in the power mechanism drives the ball screw to rotate. During the rotation of the ball screw, the upper clamping seat and the lower clamping seat are moved in opposite directions through cooperation with the connecting sleeve.

[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0021] like Figure 1-Figure 3As shown, a turbine casing milling processing and fixing device provided in this embodiment includes a main frame 1, an upper clamping seat 2 is arranged at the upper middle part of the main frame 1, and a lower clamping seat 3 is arranged at the lower middle part of the main frame 1. The turbine casing is clamped and fixed by the upper clamping seat 2 and the lower clamping seat 3. A power mechanism 4 is arranged on the outer side of the upper clamping seat 2 and the lower clamping seat 3, and the two groups of power mechanisms 4 are staggered with each other. The power mechanism 4 includes a connecting sleeve 403 fixed in the upper clamping seat 2 and the lower clamping seat 3, and the connecting sleeve 403 is used to connect the ball screw 402. The middle part of the connecting sleeve 403 is connected with the ball screw 402 by a thread. The coordinated use of the ball screw 402 and the connecting sleeve 403 can make the upper clamping seat 2 and the lower clamping seat 3 slide in the horizontal direction. A driving motor 401 is installed at one end of the ball screw 402, and the driving motor 401 can drive the ball screw 402 to rotate. The output end of the driving motor 401 is fixedly connected to the ball screw 402.

[0022] like Figure 1-Figure 2 As shown, mutually fitting grooves and protrusions are provided on opposite sides of the upper clamping seat 2 and the lower clamping seat 3, so as to facilitate the guidance and limitation of the upper clamping seat 2 and the lower clamping seat 3 when they move horizontally, thereby ensuring the stability of the movement.

[0023] like Figure 1 As shown, a support frame 5 is fixed to the outside of the driving motor 401 , and the support frame 5 is located outside the main frame 1 . The support frame 5 is an L-shaped structure, and the driving motor 401 can be supported by the support frame 5 .

[0024] like Figure 1 As shown, the support frame 5 is connected to an adjusting mechanism 6 , which includes a rotating motor 601 and an adjusting screw 602 , so as to facilitate the movement of the support frame 5 through the adjusting mechanism 6 , thereby adjusting the height of the power mechanism 4 .

[0025] like Figure 1 As shown, the output end of the rotating motor 601 is fixedly connected to the adjusting screw 602, and the adjusting screw 602 is threadedly connected to the supporting frame 5, so that the rotating motor 601 can drive the adjusting screw 602 to rotate, and the supporting frame 5 can be vertically lifted or lowered by the rotation of the adjusting screw 602.

[0026] like Figure 1 and Figure 3 As shown, a connecting block 7 is fixed on the side of the supporting frame 5 facing the main frame 1, and a guide groove 8 adapted to the connecting block 7 is opened on the main frame 1. The connecting block 7 is slidably connected to the main frame 1 through the guide groove 8. During the vertical lifting of the supporting frame 5, the connecting block 7 can slide on the main frame 1 along the guide groove 8, thereby realizing the limitation and guidance of the supporting frame 5.

[0027] like Figure 1As shown, a slot 9 for the ball screw 402 to move is provided on the main frame 1 , so that the ball screw 402 can be easily lifted and lowered along the main frame 1 through the slot 9 .

[0028] Working principle of the device: When the device is used, the adjusting screw 602 is driven to rotate by the rotating motor 601 in the adjusting mechanism 6, and the adjusting screw 602 can drive the carrier 5 to move, and the carrier 5 can drive the upper clamping seat 2 and the lower clamping seat 3 to separate from each other through the power mechanism 4. After separation, the staff will place the turbine housing between the upper clamping seat 2 and the lower clamping seat 3, and reset the dynamic adjusting mechanism 6, and the outer side of the turbine is initially clamped by the upper clamping seat 2 and the lower clamping seat 3. During the movement of the carrier 5, the connecting block 7 can slide on the main frame 1 along the guide groove 8 to achieve the limit and guidance of the carrier 5;

[0029] After the reset is completed, the driving motor 401 in the power mechanism 4 can drive the ball screw 402 to rotate. During the rotation of the ball screw 402, the upper clamping seat 2 and the lower clamping seat 3 are moved in opposite directions through cooperation with the connecting sleeve 403. The clamping and fixing of the turbine casing are achieved through the misalignment of the upper clamping seat 2 and the lower clamping seat 3. The clamping method is simple, easy to operate, and improves the work efficiency of the staff.
