液力变矩器内部间隙的焊接控制设备及方法
摘要：
本发明主要包括上盖、上顶块、上夹爪、液力变矩器泵轮、下夹爪、伺服电机、填充焊丝和焊炬,上顶块固定设置在上盖上,其下平面与上夹爪的轴线垂直,下夹爪装在伺服电机上方,下夹爪和上夹爪必须同心设置,泵轮底下凸缘安装在下夹爪内,上盖凸缘安装在上夹爪内,利用伺服电机,位置控制方式和力矩控制方式的特点,采用电控方式来保证液力变矩器泵轮内部间隙的精确控制的方法进行焊接。
摘要（英）：

A welding controller is composed of top cover, upper push block, upper clamping jaw, pump wheel of hydraulic torque converter, lower clamping jaw, servo motor, welding wire filling and welding torch.Said upper push block is fixed to top cover and its lower surface is perpendicular to the axis of upper clamping jaw. Said lower clamping jaw is above the servo motor and is concentric with said upper clamping jaw. The bottom flange of pump wheel is installed in lower clamping jaw and the flange of top cover is in upper clamping jaw. The internal gap of the pump wheel of hydraulic torque converter can be acurately controlled for welding by electric control mode as the feature of position control and torque control modes.
