[0035] like Figures 1-4 As shown, the present application provides a blade flow test fixture, comprising:

[0036] A bottom fixing plate 1, the left and right sides of the top of the bottom fixing plate 1 are fixedly connected with guide support components 2, and the top of the guide support component 2 is fixedly connected with an upper support component 7;

[0037] The top pushing component 3 is slidably connected to the middle part of the outer side of the guiding and supporting component 2, and both the left and right sides of the top of the top pushing component 3 are fixedly connected with rotating limiting components 4. The middle part of the top of the top pushing component 3 is clamped with a lower supporting component 5, and a test blade body 6 is placed on the top of the lower supporting component 5;

[0038] Rotate the top pushing screw 8. The top pushing screw 8 is threadedly connected to the middle part of the inner side of the bottom fixing plate 1, and the bottom end of the top pushing screw 8 is fixedly connected with a rotating adjusting component 9;

[0039] In this embodiment: By the combined use of the top pushing component 3 and the rotating limiting component 4, the lower supporting component 5 can be inserted and limited and blocked. The fixing stability is strong, and it is also easy to disassemble and replace. It can be adjusted according to test blades of different shapes, thereby improving the applicability of the equipment. The rotating adjusting component 9 provided at the bottom is inserted and adjusted during the rotation of the top pushing screw 8, and can achieve the effect of saving effort during the top pushing and extrusion process, improving the use efficiency of the fixture.

[0040] Specifically, as Figure 1 shown, the guiding and supporting component 2 includes guiding support rods 201, and both the left and right sides of the top of the bottom fixing plate 1 are fixedly connected with guiding support rods 201. The outer top of the guiding support rods 201 is sleeved with compression springs 202;

[0041] In this embodiment: The guiding support rods 201 connect the bottom fixing plate 1 and the upper supporting component 7, and are in the middle support of the fixture. The outer compression springs 202 can be used for limiting and buffering during the guiding adjustment process.

[0042] Specifically, as Figure 2 shown, the top pushing component 3 includes a top pushing plate 301, and the top pushing plate 301 is slidably connected to the middle part of the outer side of the guiding support rod 201. A clamping groove 302 is formed in the middle of the top wall of the top pushing plate 301;

[0043] In this embodiment: Under the push of the bottom end, the top pushing plate 301 can slide outside the guiding support rod 201 for up and down adjustment, and then perform the clamping work.

[0044] Specifically, as Figure 2 shown, the rotating limiting component 4 includes a rotating adjusting rod 401, and the rotating adjusting rod 401 is fixedly connected to both the left and right sides of the top of the top pushing plate 301. A limiting pressing plate 402 is rotatably connected to the outer side of the rotating adjusting rod 401, and a detachable screw 403 is threadedly connected to the inner end of the limiting pressing plate 402;

[0045] In this embodiment: The limiting pressing plate 402 outside the rotating adjusting rod 401 can be rotated and adjusted, and then when it is rotated to the fixed position at the top of the lower supporting component 5, the detachable screw 403 can be screwed in for fixation.

[0046] Specifically, as Figure 3 shown, the lower support assembly 5 includes a lower support module 501, and the lower support module 501 is clamped inside the clamping groove 302. An extended limit block 502 is integrally connected to the outer side of the lower support module 501, and a plug post 503 is welded to the bottom end of the lower support module 501;

[0047] In this embodiment: The lower support module 501 is stuck inside the clamping groove 302, and then the plug post 503 at the bottom end further improves the stability of the plug-in limit. By providing a threaded hole inside the extended limit block 502, it can be connected and fixed after being butted with the limit pressing plate 402 to perform top limit.

[0048] Specifically, as Figure 2 shown, the upper support assembly 7 includes an upper fixing plate 701, and the upper fixing plate 701 is fixedly connected to the top end of the guiding support rod 201. The inner bottom wall of the upper fixing plate 701 is provided with an upper support module 702, and an adjusting extrusion block 703 is connected to the top end of the upper fixing plate 701;

[0049] In this embodiment: The upper fixing plate 701 is fixedly placed at the top. The fixing method of the upper support module 702 is the same as that of the lower support module 501. By rotating the adjusting extrusion block 703, it can press down tightly on the upper support module 702 to facilitate fixed clamping.

[0050] Specifically, as Figure 4 shown, the rotation adjusting assembly 9 includes a connecting block 901, and the connecting block 901 is fixedly connected to the bottom end of the rotating pushing screw 8. A shifting rod 902 penetrates through the inside of the connecting block 901. Protective rubber rings 903 are bonded to both ends of the outer wall of the shifting rod 902, and limit retaining pieces 904 are provided on both sides of the outside of the shifting rod 902;

[0051] In this embodiment: The connecting block 901 is connected to the bottom end of the rotating pushing screw 8, which can facilitate the operator to rotate and adjust the rotating pushing screw 8, so that the rotating pushing screw 8 rotates and adjusts in the internal thread of the bottom fixing plate 1 to push and press the pushing plate 301. The shifting rod 902 can be pulled on both sides inside the connecting block 901. After rotating half a turn, the shifting rod 902 can be reset and always stay in one position for rotation adjustment. The protective rubber ring 903 protects the hand, and the limit retaining piece 904 limits the pulling of the shifting rod 902 to improve the convenience of rotation adjustment.

[0052] The specific solution of this scheme is as follows: The guiding support rod 201 connects the bottom fixing plate 1 and the upper support assembly 7, providing support in the middle of the fixture. The outer compression spring 202 can limit and buffer during the guiding adjustment process. Then, the lower support module 501 is stuck inside the clamping groove 302, and the bottom insertion post 503 further improves the stability of the insertion limit. Since there is a threaded hole inside the extended limit block 502, it can be connected and fixed after being docked with the limit pressing plate 402. The limit pressing plate 402 outside the rotating adjusting rod 401 can be rotated and adjusted. Then, when it rotates to the top fixed position of the lower support assembly 5, the detachable screw 403 can be screwed in for fixation to perform top limit. The upper fixing plate 701 is fixedly placed on the top, and the fixing method of the upper support module 702 is the same as that of the lower support module 501. By rotating the pressing block 703, it can be pressed down tightly against the upper support module 702 for easy fixing and clamping. The connecting block 901 is connected to the bottom end of the rotating pushing screw 8, which facilitates the operator to rotate and adjust the rotating pushing screw 8, enabling the rotating pushing screw 8 to rotate and adjust within the internal thread of the bottom fixing plate 1 to push the pressing pushing plate 301. The shifting rod 902 can be pulled on both sides inside the connecting block 901. After rotating half a turn, the shifting rod 902 can be reset and always rotated and adjusted at one position. The protective rubber ring 903 protects the hand, and the limit stop piece 904 limits the pulling of the shifting rod 902 to improve the convenience of rotation adjustment. Driven by the bottom end, the pushing plate 301 can slide up and down outside the guiding support rod 201, and then the clamping work is carried out.
