Description

Technical Field

[0001] The utility model relates to the technical field of impellers, and in particular to an impeller shaping device and system. Background Art

[0002] With the continuous development of industrial technology, impellers, as the core components of rotating machinery, are widely used in various fluid machinery such as water pumps, fans, compressors, etc. The performance of the impeller is directly related to the operating efficiency and service life of the mechanical equipment. However, in the production and use of the impeller, it usually involves a variety of processing techniques such as casting, welding, and cutting. Due to the influence of various factors such as materials, processes, and operating environment, there are deviations in the shape, size, and surface quality of the impeller, which affects its performance and even affects the safe operation of the entire mechanical equipment. Therefore, it is very necessary to shape the impeller to ensure that it meets the design requirements.

[0003] Existing impeller shaping methods mainly include manual grinding, mechanical processing and other methods. In order to ensure the accuracy of the impeller during the processing, it is necessary to select a suitable fixture to position and fix the impeller so that the impeller is stably placed relative to the ground. At the same time, the impeller can be rotated freely to find the position where the runout exceeds the standard, and then assisted by a correction tool. The existing shaping tool uses a double-support structure, which is inconvenient to disassemble and assemble, and often the bracket strength is insufficient and the fixed shaft strength is insufficient. It is easy to deform during shaping, resulting in inaccurate measurement data. In actual operation, there will be different types of impeller designs, but the existing shaping tooling often has only one size and cannot adapt to impellers of different types and specifications. It lacks flexibility and versatility and is limited in use.

[0153] In some of the embodiments, the measuring device 200 includes but is not limited to a micrometer and a circular runout measuring instrument.

[0154] The method of using this embodiment is as follows:

[0155] 1) After the impeller shaping device 100 fixes the position of the impeller, ensure that it can rotate freely without axial movement, then adjust the measuring device 200 to contact the radial surface of the impeller, apply a certain pressure, rotate the impeller for one circle, record the maximum reading and the minimum reading of the measuring device 200, and calculate the difference between the two, which is the radial runout error within the cross section of the impeller;

[0156] 2) Similarly, adjust the measuring device 200 to contact the end face of the impeller, apply a certain pressure, rotate the impeller for one circle, and record the maximum and minimum readings of the measuring device 200. The difference between the two is the axial runout error in the cross section.

[0157] 3) Determine the position and angle of the impeller that needs to be corrected and mark them;

[0158] 4) Reshape and correct the impeller and continue measuring until the measurement results of the measuring device 200 meet the requirements.

[0159] The technical effects of this embodiment are as follows:

[0160] By setting up a measuring device, the radial runout and axial runout errors of the impeller can be effectively measured, and corrected to qualified through the impeller shaping device, thereby ensuring the stability and reliability of the impeller during rotation and reducing safety hazards during use.

[0161] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
