我厂在成批生产或大量生产的机床上采用一种电动卡盘。经过几年的实践证明,它可以大大减轻劳动强度,缩短辅助工时,提高生产效率。电动卡盘是由动力头和专用卡盘组成,用电动机做动力,带动专用卡盘,来卡紧工件的。电动机的功率为1～1.7千瓦;卡盘的夹紧力为3000公斤;卡盘每松开或夹紧工件一次所需时间为0.3～0.7秒;在20℃室温条件下
I plant in mass production or mass production of machine tools using an electric chuck. After several years of practice has proved that it can greatly reduce labor intensity, shortening the number of auxiliary working hours and improve production efficiency. Electric chuck is made up of power head and special chuck. It uses motor to drive power and drives special chuck to clamp the workpiece. The power of the electric motor is 1 ~ 1.7 kilowatts; the clamping force of the chuck is 3000 kilograms; the time required for the chuck to release or clamp the workpiece once is 0.3 ~ 0.7 seconds; at 20 ℃ room temperature
