[0008] Preferably, the spherical positions of the fixing blocks are all located inside the accommodating grooves.

[0009] Preferably, the diameter of the fixing groove matches the diameter of the fixing block.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: a fixed block, a fixed groove, a connecting groove, a accommodating groove and a rotating disk, etc. are provided, and the rotating plate can be driven to rotate by rotating the rotating disk to squeeze the arc-shaped part of the fixed block, so that each fixed block moves in a direction away from each other at the same time, and finally is inserted into the interior of the fixed groove. When the rotating disk finishes rotating, the first thread groove on the rotating disk and the second thread groove on the frame just dock. At this time, each bolt can be connected and penetrated through the first thread groove and the second thread groove, so that the rotating disk is fixedly connected to the frame. It is convenient to install and also convenient to disassemble the rotor part, so as to achieve the purpose of facilitating the replacement and maintenance of the rotor, and it is highly practical.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4The utility model provides a technical solution: a blade machine rotor internal support frame assembly, including a frame 1 and a rotor 2, a rotating groove 3 is opened on the frame 1, a rotating disk 4 is rotatably connected inside the rotating groove 3, a plurality of first thread grooves 5 arranged in an array are opened on the rotating disk 4, a plurality of second thread grooves 6 arranged in an array are opened at positions corresponding to the rotating groove 3 on the frame 1, a rotating piece 7 is fixedly connected to the back wall of the rotating disk 4, an annular groove 8 is opened at a position corresponding to the rotating piece 7 inside the frame 1, a plurality of connecting grooves 9 arranged in an array are opened at positions corresponding to the annular groove 8 on the frame 1, a fixed block 10 is slidably connected inside the plurality of connecting grooves 9, a receiving groove 11 is opened at a position of the rotating piece 7 corresponding to the fixed block 10, and a fixed groove 12 is opened at a position of the rotor 2 corresponding to the fixed block 10.

[0018] Furthermore, the rotating piece 7 is rotatably connected inside the annular groove 8 .

[0019] Furthermore, the fixing blocks 10 corresponding to the inner positions of the receiving grooves 11 are all spherical in shape.

[0020] Furthermore, the spherical positions of the fixing block 10 are all located inside the receiving groove 11 .

[0021] Furthermore, the diameter of the fixing groove 12 matches the diameter of the fixing block 10 .

[0022] Specifically, when using the utility model, the rotor 2 can be mounted on the frame 1 at the position corresponding to the fixed block 10, and then the external tool can be inserted into the first threaded groove 5, and then the external tool can be used to rotate the rotating disk 4 clockwise. The rotation of the rotating disk 4 will drive the rotating piece 7 to rotate, and the rotation of the rotating piece 7 will cause the accommodating groove 11 to gradually separate from the spherical position of the fixed block 10. When the fixed block 10 is no longer located in the accommodating groove 11, the outer wall of the rotating rotating piece 7 will squeeze the spherical position of the fixed block 10. At this time, each fixed block 10 will be squeezed and move toward the fixed groove 12 on the rotor 2. Finally, the fixed blocks 10 will be inserted into the fixed groove 12 on the rotor 2.
