[0035] After completion, the driving motor 12 is operated and the rotating shaft 101 is driven to rotate through the transmission belt 5. The rotation of the rotating shaft 101 can be sensed by the detection sensor 34 to understand its balance state, and the detection data is transmitted to the control host. The control software in the control host can understand the condition of the rotating shaft 101 and whether it meets the dynamic balance requirements. This detection sensor 34 and the detection principle are the same as the existing ones, so they are not described in detail.

[0036] After the detection is completed, it is only necessary to retract the push rods of all the clamping cylinders 24 and move the oil-free vortex air compressor head 100 to the right. During the movement, the transmission belt 5 is disengaged from the rotating shaft 101, and disassembly is achieved, which is very convenient. It is easy to load and unload, greatly improving the detection efficiency.

[0037] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
