摘要： A C-type welding gun capable of accurately operating irrespective of the posture of the C-type welding gun without forcibly pressing electrodes to a workpiece and without considering thickness of the workpiece, wear of electrodes, etc. The C-type welding gun includes two servomotors attached to a housing, a C-shaped arm fixed to the housing and a movable arm provided in the housing. A mechanism for converting the rotation of the output shaft of one servomotor into the reciprocal motion of the movable arm is housed in the housing. A mechanism for converting the rotation of the output shaft of the other servomotor into the reciprocal motion of the C-shaped arm is provided between the wrist of the robot and the housing. Both the servomotors are simultaneously actuated while the other servomotor is stopped in response to the signal representing the contact of the electrode of the C-shaped arm to the workpiece.

摘要翻译： 一种C型焊枪，无论C型焊枪的姿势如何，都不会强制地将电极压向工件，而不考虑工件的厚度，电极的磨损等，C型焊枪可以精确地工作.C型焊枪包括两个 连接到壳体的伺服电动机，固定到壳体的C形臂和设置在壳体中的可动臂。 用于将一个伺服电机的输出轴的旋转转换成可动臂的往复运动的机构容纳在壳体中。 将机器人的手腕与壳体之间设置用于将另一伺服电机的输出轴的旋转转换为C形臂的往复运动的机构。 响应于表示C形臂的电极与工件的接触的信号，两个伺服电机同时致动而另一个伺服电动机停止。
