HE-Grinding Plant

The semi-automatic hydro erosive grinding module has been designed for flow calibration of high-pressure injection components to a defined target. The single station is thereby loaded manually by the operator.
During the grinding process an abrasive fluid is pumped
through the orifices of the work pieces in order to radius bore
hole intersections. The flow will be increased and stopped as soon as the flow has reached the correlated target flow value.
A moveable control panel with a comfortable user interface is installed. Running processes and results are displayed. The parameters can be easily adjusted in case of changing requirements.

Injector fine adjustment

The mainly manually Station is used to measure and adjust the open and closetime of diesel injectors.
The Injectors are manually loaded, manually adjust, and manually released.
The measurement and calculation of the open and closetime and the calculation of the adjustment angle is fully automated.
The serial number is recorded by a Camera.
Parameters like set point, measurement time and maximum time to read the code are changeable.
The most parameters can also be set in a test plan.
The open and closetime is measured by a Nation Insruments card with a Sampling rate of 25 M samples per second. Due to the high resolution, exact results are possible.

Backleak test bench

This test bench tests the back leakage from a component of a diesel fuel injector. Leak flow is an indicator of the quality of the guide gap. Precise measurement of the guide gap is used to classify the test part quality and to provide feed back for adjusting the production process upstream. An Active Flow Meter (AFM) creates the pressure required for testing. Flow measurement is also done by the AFM. A variety of test plans and manual test part feed means that quality control measurements and tests can be carried out in a very short time. With automatic test part feed, the back leak tester has a cycle time of less than 30 seconds at a wide pressure range. Set point pressures up to 300 bar can be reached within 7 seconds. All the measurement data can be easily imported into the tables customarily used for calculations and data processing.

Robot loader for 2 EDM machines

The loader serves for fully automatic loading and unloading of 2 EDM machines with integrated flow measurement of finished parts. The parts are delivered to the robot cell by means of two drawers. One robot distributes the parts to the erosion machines, measuring station and conserving system. After conserving the IO parts are again deposited in the drawers. The NIO parts are transported to a box.

Nozzle Orientation System

This machine has been designed for orientation of nozzle bodies which do not have any dowel holes. Injector body, nozzle body and retainer have to be assembled. By means of a vision control system the machine orientates the nozzle body to the injector body by defined spray hole angle. Retainer and injector body are screwed together by controlled torque and angle. After the assembly process, the spray hole angle is measured again.

Manual Flow Stand

The test bench has been designed for the determination of the static flow of diesel injection components. The operator holds the part in front of the camera that reads the DMC of the part. The testplan is selected automatically by using the part number of the work piece. Thereafter the part is loaded into the measuring station. The operator start the process by pressing the two-hand start button. After the measurement the part is blown off.
