[0002] A blade is a part of a tool, weapon or machine, and its edge is designed to pierce, cut or scrape the surface of a material. The blade can be made of materials such as flint, metal usually steel, ceramic or other materials. The blade is one of the oldest tools of mankind and has been used in actual combat, food preparation and other uses.

[0003] There are many shapes of hub blades, including polygonal and circular ones. A small round hole is provided in the middle of the circular hub blade to install the hub blade on the rotating shaft of the device. In the process of machining the circular hub blade, in order to increase the accuracy, concentricity detection is generally required.

[0047] On the detection table 5, a rotating disc 15 is installed through the driving assembly 2, so that the rotating disc 15 can be driven to rotate by the driving assembly 2. At a position near the outer surface at the top end of the rotating disc 15, a plurality of supporting bolts 14 are installed through a plurality of pressure sensors 16.

Above the rotating disc 15, a fixed disc 12 with a second micrometer 24 is installed through the second telescopic rod 10 and the mounting bracket 11. The position of the second micrometer 24 is adjusted through the adjusting bolt 25 to make it contact with the inner circular surface of the hub circular blade. In this process, the stabilizing rod 26 can increase the stability of the movable plate 23. The outer and inner circular surfaces of the hub circular blade can be detected simultaneously by using the first micrometer 8 and the second micrometer 24. In actual use, first place the hub circular blade on the plurality of supporting bolts 14 and ensure that the hub circular blade is located at the center position above the rotating disc 15. Then start the second telescopic rod 10 to push the fixed disc 12 downward, so that the plurality of auxiliary wheels 22 contact the top end of the hub circular blade and cooperate with the supporting bolts 14 to clamp and fix the hub circular blade. After that, only need to adjust the position of the second micrometer 24 through the adjusting bolt 25 to make it contact with the inner circular surface of the hub circular blade. At the same time, start the first telescopic rod 6 to make the first micrometer 8 contact the outer surface of the hub circular blade and record the data of the first micrometer 8 and the second micrometer 24 respectively. Then the driving assembly 2 can drive the rotating disc 15 to rotate, and cooperate with the auxiliary wheels 22 to drive the hub circular blade to rotate. In this process, the concentricity of the outer and inner circular surfaces of the hub circular blade is detected by the first micrometer 8 and the second micrometer 24.

[0048] Compared with the related technology, the hub blade concentricity detection device provided by the present utility model has the following

[0049] Beneficial effects:

[0050] In order to facilitate the fixation and improve the detection efficiency during the concentricity detection of the hub circular blade, a rotating disk 15 is installed on the detection table 5 through a driving component 2, so that the rotating disk 15 can rotate by the power provided by the driving component 2. At a position near the outer surface of the top of the rotating disk 15, a plurality of supporting bolts 14 are installed through a plurality of pressure sensors 16. The pressure sensors are used to monitor whether the pressures received by the supporting bolts 14 are consistent, so as to judge whether the hub circular blade is placed flat. Above the rotating disk 15, a fixed disk 12 with a second micrometer 24 is installed through a second telescopic rod 10 and a mounting bracket 11. The position of the second micrometer 24 is adjusted through an adjusting bolt 25 to make it contact with the inner circular surface of the hub circular blade. During this process, a stabilizing rod 26 can increase the stability of the movable plate 23. The outer circular surface and the inner circular surface of the hub circular blade can be detected simultaneously by using the first micrometer 8 and the second micrometer 24.
