Description

Technical Field

[0001] The utility model relates to the field of blowers, and in particular to a clamping mechanism and a blower. Background Art

[0002] The blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (also oil tank), and oil drip nozzle. The blower operates by the eccentric rotor offset in the cylinder, and the volume change between the blades in the rotor slot causes the air to be sucked in, compressed, and expelled. During operation, the pressure difference of the blower is used to automatically send lubrication to the oil drip nozzle and drip into the cylinder to reduce friction and noise, while keeping the gas in the cylinder from flowing back. This type of blower is also called a sliding vane blower. The motor shaft of the motor part of the blower needs to be inspected during the production process. When inspecting the existing blower motor shaft, the motor shaft needs to be clamped. The diameters of multiple positions of the motor shaft are slightly different. The existing motor shaft detection clamping mechanism is not convenient for adjusting the clamping mechanism according to the thickness of different positions of the motor shaft, making the clamping effect relatively general. At the same time, it is often only suitable for clamping motor shafts of a single model and a single thickness, and the practicality is relatively general.
