[0065] refer to Figure 2 as well as Figure 3 As shown, in some embodiments, the blisk 200 includes a disk core 201, a spoke plate 202, an outer wall 203 and a blade portion 204 from the inside to the outside in the radial direction, a mounting edge 205 is provided on the outer wall 203, and a disk core hole 206 is provided on the disk core 201. The fixture 100 for fixing the blisk includes a first support seat 1, a second support seat 2 and a third support seat 3.

[0066] The first support seat 1 includes a first support seat body 11 and a movable pressing block 12. The movable pressing block 12 is arranged on the first support seat body 11.

[0069] The specific steps of fixing the integral blade disk 200 to the fixture 100 may be, firstly, setting the integral blade disk 200 on the first mounting surface 111 provided by the first support seat body 11 through the mounting edge 205, and then moving the movable pressure block 12 to the first clamping position, so that the first mounting surface 111 and the second mounting surface 121 can clamp and fix the mounting edge 205 on both sides in the height direction. At this time, the disk core 201 is supported by the third mounting surface 211 provided by the second support seat body 21, and the movable cover body 22 providing the fourth mounting surface 221 is moved to the second clamping position, and the third mounting surface 211 and the fourth mounting surface 221 can clamp and fix the disk core 201 on both sides in the height direction. Thereafter, the first clamping portion 31 is moved to a position abutting against the bottom of the blade portion 204 to provide a fifth mounting surface 311 to support the blade portion 204, and then the second clamping portion 32 providing the sixth mounting surface 321 is installed to the first clamping portion 31, so that the fifth mounting surface 311 and the sixth mounting surface 321 clamp and fix the blade portion 204 on both sides in the height direction.

[0070] The beneficial effects of the clamp introduced in the above embodiment include but are not limited to the over-positioning structure of clamping and fixing the installation edge by the first support seat and clamping and fixing the disk core by the second support seat, combined with the clamping structure of the blade portion by the third support seat, so that the overall blade disk, especially the one-piece multi-stage overall blade disk, is subjected to sufficient clamping force during processing, thereby avoiding the problem of easy movement during the processing process, and at the same time enhancing the rigidity of parts and clamps, reducing the deformation of parts during processing, and improving the processing efficiency of parts; in addition, the fixing process of the clamp is simple to operate. For integral blade disks of different models and sizes, only some components need to be replaced to complete the clamping, which can effectively improve the versatility of the tooling, shorten the preparation cycle of the tooling, and reduce processing costs.

[0071] Continue to refer Figure 2 as well as Figure 3As shown, in some embodiments, the structure of the first supporting body 11 can be that the first supporting body 11 includes a step structure 110, the step structure 110 provides a first mounting surface 111 on the low side in the height direction, and a movable pressure block 12 is provided on the high side in the height direction. When the movable pressure block 12 moves to the first clamping position, the second mounting surface 121 passes over the step structure 110 and clamps the mounting edge 205 on both sides of the height direction with the first mounting surface 111. The beneficial effect of adopting the step structure is that its structure is simple, and the step structure 100 can also limit the movement of the mounting edge 205 on the radial inner side at the same time, further enhancing the fixing effect of the clamp. Preferably, continue to refer to Figure 2 as well as Figure 3 As shown, in some embodiments, the movable pressure block 12 is a rotating member, which can rotate around a pivot provided on the first support seat body 11, and the pivot is provided by a first threaded connector 13. The step structure 110 is provided with the first threaded connector 13 on the high side in the height direction, and a limit pin 14 is also provided, and the limit pin 14 provides a limit for the movable pressure block 12 to rotate to the first clamping position. The first threaded connector 13 can be, for example, a bolt member. Before installing the integral blade disk 200, the movable pressure block 12 is set in a non-clamping position to avoid interference with the mounting edge 205 during installation. When clamping is required, the movable pressure block 12 is rotated until it is limited by the limit pin 14, and then rotated to the first clamping position, and the first threaded connector 13 is locked by the nut 131. Thereby, clamping of the mounting edge 205 is provided. It can be understood that the movable mounting block 12 is not limited to the pivot rotation described above, for example, it can also be a linearly movable pressure block, and when clamping is required, the movable pressure block 12 is linearly moved to the first clamping position to provide clamping. The beneficial effect of adopting a rotating structure is that it is easy to control and limit the movement. Preferably, the structure of the movable pressure block 12 can also be that the movable pressure block 12 has an L-shaped bend 120, and the L-shaped bend 120 provides a second mounting surface 121 and a second positioning surface 122 perpendicular to the second mounting surface 121. The L-shaped bend structure can also provide a limit to the movement of the mounting edge 205 on the radial inner side, further enhancing the fixing effect of the clamp.

Before the first support seat 1 and the second support seat 2 clamp and fix the integral blade disk 200, the height of the movable support rod 310 is set to the lowest position. After the first support seat 1 and the second support seat 2 clamp and fix the integral blade disk 200, the top end of the movable support rod 310 is first moved to a position abutting against the lower side of the blade portion 204, providing a fifth mounting surface 311 for supporting the blade portion 204, and the bottom end of the movable support rod 310 is connected to the locking sleeve 312, and the movable support rod 310 and the locking sleeve 312 are locked by a locking member 313, such as a locking nut, to fix the movable support rod 310. In addition, in some embodiments, the second clamping part 32 includes a first plate 320 connected to the movable support rod 311, a second plate 322 arranged opposite to the first plate 320, and a connecting member 323 connecting the two; wherein the second plate 322 provides a sixth mounting surface 321; the first plate 320, the second plate 322 and the connecting member 323 form a U-shaped structure. The structure of the connecting member 323 can be as shown in the figure, including a screw 3231, a guide sleeve 3232, and a guide shaft 3233, wherein the guide sleeve 3232 connects the second plate 322, the guide shaft 3233 connects the first plate 320, and the screw 3231 connects the guide sleeve 3232 and the guide shaft 3233, thereby connecting the first plate 320 and the second plate 322. The beneficial effect of using the above third support seat 3 is that it is easy to perform the clamping operation, and it is easy to replace according to the size and shape of different blade parts, and the clamp has good versatility.

[0074] Continue to refer Figure 2 as well as Figure 3 As shown, the fixture 100 may further include a base 4, and the first support base 1 and the third support base 3 are fixed to the base 4.
