摘要： A weld cylinder having a single piston arrangement is provided. The cylinder has a movable retract piston assembly with the piston arranged within the retract piston assembly. The piston supports a rod that is movable between home, intermediate, work, and advanced work positions. The rod moves rapidly from the home position to the intermediate position however, the rod moves more slowly from the intermediate position to the work position to reduce the impact force. A cushion chamber slowly exhausts through a pre-orifice and a hole in the cushion valve while an isolator is in an open position. Once the cushion valve opens in response to a retract-forward pressure on the cushion valve, the cushion chamber exhausts rapidly so that weld force increases rapidly to minimize increases in cycle time. Advance of a retract piston assembly is also cushioned. A weld-forward port is no longer provided on a cylinder barrel.
摘要翻译：提供具有单个活塞装置的焊接圆筒。气缸具有可移动的缩回活塞组件，活塞设置在缩回活塞组件内。活塞支撑可在家庭，中间，工作和高级工作位置之间移动的杆。杆从原始位置快速移动到中间位置，但是杆从中间位置更慢地移动到工作位置以减小冲击力。当隔离器处于打开位置时，缓冲室缓慢地通过缓冲阀中的预孔和孔排出。一旦缓冲阀响应于缓冲阀上的向前压力打开，缓冲室迅速排出，使得焊接力快速增加，以最小化循环时间的增加。缩回活塞组件的推进也被缓冲。气缸筒上不再设有焊接前进端口。

摘要： A securing system, such as a welding system, includes a robot configured to transfer a part to a home position. A securing station has a frame and a gun supported on the frame. The gun includes first and second members movable relative to one another, which are first and second weld gun electrodes, for example. The gun is configured to secure a component to the part in a securing position during a securing operation. A float assembly interconnects the gun to the frame and is configured to permit the gun to glide relative to the welding frame between the home position and the securing position. A homing assembly includes a homing guide configured to release the welding gun from the home position during the securing operation, such as resistance welding fasteners to sheet metal workpieces.

摘要： A soft-touch pneumatic drive unit for welding is provided. The drive unit includes a first section, a second section, and a third section. A piston rod extends substantially throughout these sections and contains a drive piston in the second section and a second drive piston in the third section. Pressurized fluid is supplied through the first section and into the second section to provide a driving force on these pistons. Cushioning fluid is supplied through the first section to the second section to cushion and slow the piston rod as an electrode carried thereby is moved toward a workpiece. A floating piston in the second section then blocks the flow of cushioning fluid from the first section with fluid pressure in the second section then decreasing to atmospheric pressure to enable full welding force to be applied through the drive pistons and the piston rod to the electrode. The cushioning fluid also aids in returning the piston components to the retracted position upon the completion of a weld.
