摘　　要：潜水搅拌机是污水处理中的高效能设备之一,随着污水治理需求增加,潜水搅拌机需求也快速增加,为此,设计一条潜水搅拌机综合装配生产线增加产能,且适应各规格型号搅拌机的生产。作为潜水搅拌机中旋转动力部分的电机转子,其轴承压装要求是关键,即保证前后轴承压装后同心度和轴承不受损伤,保证转子的回转精度和产品的使用寿命,需设计轴承压装的配套专机。其动作步骤:通过PLC程序控制设定不同规格型号压装轴承的行程及压力要求;结构设计部分,设计轴承自动供料装置;转子自动供料至规定位置,由移载机自动抓取并放置在V形支架上,再通过油缸进行压装。压装时设有行程控制、压力传感器、V形支架中心高校准器等措施,确保轴承压装符合要求。4年多的应用结果表明,产品在污水处理运行过程中,其轴承损坏的故障下降率达到56%,经济效果明显,值得同行推广借鉴。The diving mixer is one of the high-efficiency equipment in the sewage treatment,along with the sewage treatment demand increases,the diving mixer demand also increases rapidly,therefore,a submersible mixer integrated assembly line to increase production capacity is designed,which is adapted to the various specifications of mixer production.As the rotating power part of the motor rotor in the submersible mixer,the requirement of bearing press mounting is the key,that is,to ensure the concentricity of the front and rear bearing after press mounting and the bearing is not damaged,to ensure the rotating accuracy of the rotor and the service life of the product,which need to design the bearing press machine.The action steps:setting the stroke and pressure requirements of different types of press-fit bearing by PLC program control;structure design part,design the bearing automatic feeding device;rotor automatic feeding to the specified position,the load-shifting machine automatically grabs and places it on the v-shaped bracket,and then presses and installs it through the oil cylinder.Travel control,pressure sensor,V-type bracket center height calibrator and other measures are provided to ensure that the bearing is pressed to meet the requirements.Four years' applicaion verifies that,during the operation of sewage treatment,the failure rate of bearing damage reaches 56%,the economic effect is obvious,and it is worth to use for reference.
