Flexible positioning and pressing bearing device for motor rotor

Technical Field

The invention relates to the field of motor assembling machinery, in particular to a motor rotor pressure bearing device.

Background

Along with the rapid development of science and technology in the field of home and abroad, various industries also pay more and more attention to the construction and application of automatic production lines, and along with the popularization and the promotion of automatic equipment, the requirements of various automatic equipment are greatly increased. The motor is used as a rotary transmission product, and can be used in both rotary transmission and linear transmission occasions, so that the shadow of the motor can be seen in most mechanical transmission mechanisms of mechanical automation equipment, and the demand of equipment manufacturers in the automation field on the motor products is increased. Therefore, in order to meet the increasingly strong market demand of customers for motor products, various motor manufacturers and suppliers have begun to make various ideas to shorten the production cycle of the motor and improve the production and manufacturing efficiency, and it is an effective method to change the conventional motor production mode of manual assembly line assembly operation into the motor automatic production line mode, so that the motor automatic production equipment is gradually popularized and applied in various motor production and manufacturing enterprises.

From the existing motor production and manufacturing process, the motor mainly comprises a stator and a rotor, the stator and the rotor of the motor are important parts for converting electric energy into mechanical energy, and the links of the production and assembly of the stator and the rotor of the motor cannot be left no matter in a traditional manual operation mode or an automatic production mode at the present stage. The motor rotor is used as a rotating body of motor torque output, the motor rotor is one of the most important components in the motor as a middle core body of the motor, and in order to ensure the stability and precision of the rotation of the motor rotor in the production process, parts such as a fixed shaft sleeve, a bearing and the like are often required to be respectively installed at two ends of a motor rotor shaft, so that the assembly of the motor rotor in the common way usually refers to a process of installing the fixed shaft sleeve and the bearing on the motor rotor shaft, and the quality control and the production efficiency of the production and assembly link of the motor rotor often determine the quality and the production period of the whole motor. Although the production and assembly links of the motor rotor can be basically completed by equipment automation along with the popularization and application of the motor automatic production line at the present stage, the existing automatic assembly production links of the motor rotor still have the problem of positioning when the motor rotor is assembled, which needs to be solved urgently.

The more prominent problem is that a positioning fixture for a motor rotor can only be used for a motor rotor product of a specific model (for example, a patent with a patent number of CN202021484426.6 is named as a pneumatic rotor bearing mounting and positioning device), and when a motor rotor of a different model is replaced, a corresponding rotor positioning fixture needs to be manually replaced first, which results in strong pertinence, low adaptability, poor universality and low flexibility of the motor rotor positioning fixture. For some devices applicable to positioning of various types of motor rotors, although the device can meet the requirement of coaxial positioning of various types of motor rotors, the positioning device for positioning the motor rotors is often required to be manually adjusted according to different motor rotor products (for example, a patent with the patent number of CN202021803765.6 is named as a motor rotor bearing press-fitting device), which not only is complicated and time-consuming in operation process, but also has certain requirements on the technical level of operators, and is extremely not favorable for quality control and automatic production. Therefore, once the motor automatic production line changes different motor products, the automatic motor rotor assembly link must be manually replaced by a corresponding rotor positioning jig or manually adjusted by a rotor positioning device, regardless of which mode is adopted, the problems of high pertinence, low adaptability, poor universality, complex adjustment, time consumption, low flexibility degree and low efficiency of motor rotor assembly positioning still exist, and how to solve the problems becomes one of the difficult problems which need to be considered and treated by modern motor production and manufacturing enterprises urgently.
