Description

Pneumatic bearing press-fitting machine Technical Field The utility model relates to the technical field of bearing press-mounting machines, in particular to a pneumatic bearing press-mounting machine. Background The bearing is a key component for supporting rotary mechanical parts, is commonly used in mechanical systems in various industrial equipment, automobiles, aerospace and other fields, and has the functions of reducing friction, supporting and positioning a rotating shaft, so that the mechanical parts can stably run, stress is not concentrated due to repeated knocking and extrusion force of the bearing under uneven assembly in the assembly process of the bearing, the inner ring, the outer ring and the rolling element of the bearing are easy to deform, the bearing runs and rubs, and the service life of the bearing parts is finally influenced, so that the bearing and the assembly shaft are ensured to be in accordance with standards in the bearing press-fitting process. In daily life, when the bearing is required to be installed on the shaft part, the copper bar is generally clung to the end face of the inner ring of the bearing in a manual knocking mode, the copper bar is directly knocked by a manual hammer, force is transferred through the copper bar, and the bearing is slowly installed on the shaft. If the bearing inner ring is bigger, the copper rod can be used for uniformly and forcefully knocking along the periphery of the end face of the bearing inner ring, so that only one side is knocked or forcefully used for preventing the bearing from being inclined or cracked. The sleeve can be directly pressed on the end face of the bearing, and is knocked by a hand hammer, so that the pressure is uniformly distributed on the end face of the whole ferrule, the press-fitting device has insufficient precision, the bearing is easy to deform, the coaxiality is deviated, the rejection rate is high, the press-fitting process efficiency is low, the operation danger coefficient is high, the working intensity of workers is high, and the batch production cannot be realized; Later, the automatic pressing machine for the bearings appears on the market, a positioning fixture structure, an automatic feeding mechanism and an automatic pressing device are adopted, a cylinder and a motor are driven to operate, and automatic assembly is achieved, but the automatic pressing machine for the bearings is difficult to ensure the accurate coaxiality of the bearings and a shaft or a bearing seat in the installation process due to the lack of a correction mechanism, the skew installation of the bearings can lead to uneven stress of rolling bodies inside the bearings, local bearing over-high pressure is achieved, bearing abrasion is accelerated, and the service life is shortened. Therefore, a new technical solution is needed to solve the above problems.
