The invention discloses an
assembly line for a hydraulic tensioner. The
assembly line is a highly automatic and
integrated production system. The
system is mainly composed of an annular conveying line, a plurality of
assembly stations, a control cabinet and a
manipulator. The annular conveying line serves as core conveying equipment and is responsible for conveying workpieces between different assembly stations, and it is guaranteed that all procedures are carried out orderly. Each assembly
station is connected with the control cabinet, and accurate control over the whole assembly process is achieved through the control cabinet. The
assembly line is further particularly provided with a workpiece tray feeding area for corresponding stations to use. In addition, a stop pin
punching device is arranged on the pull rod assembling
station, and necessary drilling operation can be carried out on the cylinder body. The pressure maintaining
test station adopts a dual-detection mode, and a sensor is arranged to monitor the displacement change of the ejector rod in real time, so that accurate recording of data is ensured. On the whole, the
assembly line achieves the one-stop automatic production process from
raw material supply to finished product output, and the working efficiency and the product quality are greatly improved.
