Valve Assembly Machine
Metering Valve Assembly Equipment is a highly accurate semi-automatic
Press machine designed for Pressing the components namely Metering valve
body and Arm. The machine also performs the proof load test after assembling
the Metering valve. Error free sequential operation is ensured with the
help of positive feedback interlocks interfaced to the DAQ Module.
basic structure is fabricated out of MS plates with intermittent support
ribs. All the sub assemblies are mounted on to the scrapped surfaces.
This machine mainly consists of a hydraulic operated ram unit, proof test
assembly and Fixtures. The fixtures are provided with non-contact sensors
for component mistake proofing. All the co – ordination movements
are performed by the hydraulic cylinders. The ram and proof test assemblies’
houses the load-measuring device. High-resolution linear scales used for
monitoring the position feedback of assembly cylinder and proof test cylinder
during the sequence.
curtain has been provided in the area of operator viscinity for safety.
Suitable sheet metal / acrylic guards have been provided wherever applicable.
The control system is based on industrial standard and highly reliable
DAQ modules. It takes care of sequencing of all the operating elements
in correlation with the feedback from various status sensor inputs. The
associated basic electrical control & safety circuits suitably support
the control subsystem.
PC add-on DAQ module namely PCL-812 is used for measuring the analogue
signals from the load sensors in addition to providing the interface for
the necessary I/O controls. Another card namely PCL-833 has been used
for monitoring the high precision output from the linear scale (MT 25).
