去年,我厂和西安交通大学电机专业一起,试制了几台φ250毫米整体式电动三爪自定心卡盘。经过切削试验,性能良好。整体式电动卡盘工作原理整体式电动卡盘(图1)是将专门设计的低速同步电动机与卡盘连成一体,用电机的转子直接拨动盘丝转动,使卡爪开合。碳刷架部分固定在车床主轴箱前端。三相电源通过碳刷和法兰盘背后的铜环连接,将电压加至低速同步电机定子绕组上。低速同步机是专门为电动
Last year, I plant and Xi’an Jiaotong University, motor professional together, trial production of several φ250 mm integral electric three-jaw self-centering chuck. After cutting test, the performance is good. Integral electric chuck works Integral electric chuck (Figure 1) is a specially designed low-speed synchronous motor and chuck into one, with the rotor of the motor directly to dial the wire rotation, the jaws open and close. Carbon brush holder part of the fixed headstock in the lathe. The three-phase power supply is connected to the copper windings on the back of the low-speed synchronous motor by the carbon brush and the copper ring behind the flange. Low-speed synchronous machine is designed for electric
