Description

Technical Field

[0001] This utility model relates to the field of diffuser testing technology, and in particular to a compressor diffuser testing device. Background Technology

[0002] The diffuser is an important component of the compressor, which can convert the velocity energy of gas into pressure energy. In this process, the gas flow rate slows down and the pressure increases, so that the gas can be effectively utilized to meet the specific pressure requirements of industrial production. Diffusers include wedge blade diffusers. After the diffuser is manufactured, it is necessary to use testing equipment to test the thickness, profile, chord length, chord angle, etc. of its blades in order to screen out unqualified products.

[0003] Existing diffuser testing equipment requires the diffuser to be fixed to the rotating part by a clamp. The rotating part then drives the diffuser to rotate and change the orientation of the test blades towards the probe. This makes the process of installing and disassembling the diffuser cumbersome and inconvenient to use.

[0004] Existing diffuser testing equipment uses a contact measurement method with probes to test blades, which requires contacting each blade individually for measurement, resulting in long testing time and low efficiency.

[0005] To address this issue, a compressor diffuser testing device is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-6 A compressor diffuser testing device includes a base plate 1 and a diffuser body 23. The surface of the base plate 1 is provided with a positioning groove 2 to facilitate quick positioning by the tester. A tray 3 is placed in the positioning groove 2. A mounting seat 4 is provided at one end of the surface of the base plate 1. An intermittent rotary motor 5 is provided at the top of the mounting seat 4 corresponding to the tray 3. A rotating component is provided at the bottom of the mounting seat 4 corresponding to the tray 3. A baffle 6 and an electric push cylinder 7 are respectively provided on opposite sides of the rotating component. A scanning component is provided at the output end of the electric push cylinder 7. The diffuser body 23 is placed on the top of the tray 3.

[0026] Furthermore, multiple extension rods 8 are fixedly connected to the surface of the tray 3 corresponding to the diffuser body 23, so that the scanner 21 can scan the diffuser body 23 from the bottom. The top of the extension rods 8 is fixedly connected to a rubber pad 9 for increasing friction, which makes it easier for the tester to place the scanner 21.

[0027] Furthermore, the rotating assembly includes a connecting block 10, with a rotating shaft 11 fixedly connected to the top of the connecting block 10, a short support rod 12 fixedly connected to one side of the connecting block 10, and a long support rod 13 fixedly connected to the other side of the connecting block 10. The top of the rotating shaft 11 passes through the mounting base 4 and is connected to the rotor of the intermittent rotary motor 5. One end of the short support rod 12 is fixedly connected to the baffle 6 to support scanning. One end of the long support rod 13 is fixedly connected to one side of the electric push cylinder 7. The long support rod 13 extends the distance between the scanner 21 and the diffuser body 23, so that the scanning area of ​​the scanner 21 can completely cover the diffuser body 23.

[0028] A further advantage of the above is that by driving the rotating assembly to rotate via the intermittent rotary motor 5, the scanner 21 surrounds and scans the diffuser body 23, thereby eliminating the need to install and disassemble the diffuser body 23 during the testing process. The testing can begin simply by placing the diffuser body 23 in the appropriate position, achieving a user-friendly effect.

[0029] Furthermore, the scanning assembly includes a base 14, the top of which is fixedly connected to the output end of the electric push cylinder 7. A data cable 15 is fixedly connected to one side of the base 14, and a rotating seat 16 is provided on the other side of the base 14. A pitch block 17 is rotatably connected to the rotating seat 16. A slot 18 is fixedly connected to one side of the pitch block 17. A plug 19 is inserted into the slot 18. A connecting plate 20 is fixedly connected to one side of the plug 19. A scanner 21 is fixedly connected to one side of the connecting plate 20. A USB interface 22 is provided at the output end of the scanner 21. The USB interface 22 is connected to the data cable 15 and the scanning data is transmitted through the USB interface 22.

[0030] A further advantage of the above approach is that, through the combined action of the rotating component and the scanning component, the scanner 21 performs a full-size scan of the diffuser body 23 using a three-dimensional scanning method. The scanned data is transmitted to the base 14 via the USB interface 22, and then output from the base 14 to the test computer. The data is analyzed using existing analysis software and presented as a model, eliminating the need for blade-by-blade measurement and improving detection efficiency.

[0031] When using this utility model, the tester places the tray 3 in the positioning groove 2 and places the diffuser body 23 on top of the rubber pad 9. Since the scanner 21 scans around the diffuser body 23 by rotating the component, there is no need to fix the diffuser body 23, which improves the convenience of placement.

[0032] When performing the first scan, the electric push cylinder 7 extends to align the scanner 21 with the diffuser body 23 in the horizontal direction. Then, the intermittent rotary motor 5 is started, which drives the scanner 21 to rotate intermittently around the diffuser body 23. The scanner 21 scans the diffuser body 23 when the intermittent rotary motor 5 stops briefly. After the scanner 21 has rotated 360° intermittently, the first scan is completed.

[0033] Similarly, during the second scan, the electric push cylinder 7 extends further, positioning the scanner 21 below the diffuser body 23. Then, the rotating base 16 drives the pitch block 17 to rotate upwards to a suitable position, and the intermittent rotary motor 5 and scanner 21 are started for scanning. During the third scan, the electric push cylinder 7 retracts, positioning the scanner 21 above the diffuser body 23. Then, the rotating base 16 drives the pitch block 17 to rotate downwards to a suitable position, and the intermittent rotary motor 5 and scanner 21 are started for scanning, completing the scans at three angles. The scan data is output to the base 14 via the USB interface 22, and then output from the base 14 to the test computer. The data is analyzed using existing analysis software and presented as a model, eliminating the need for leaf-by-leaf measurement and improving detection efficiency.

[0034] When it is necessary to disassemble the scanner 21, unplug the data cable 15 from the USB interface 22, then slide the scanner 21 upwards, and the insert 19 will slide out of the slot 18 through the scanner 21 to complete the disassembly.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
