Abstract
A method is disclosed for verifying the alignment of a door with a door opening defined by a vehicle body sub-assembly. Sets of two-way sensors and a four-way sensors are used to locate feature, or hole, locations including a master hole location on the body/side. Other two-way sensors and four-way sensors are used to locate door hanging fixture pin locations on the doors before the doors are assembled to the body/side. After the doors are assembled to the body/side, two-way sensors and four-way sensors locate feature, or hole, locations on the installed doors and compare them to the previously measured master location.
Claims15
A method comprising:
- sensing an X/Z location of featureR1 relative to an X/Z location of featureR2 on a body/side to establish an axisbs extending through featureR1 and featureR2;
- sensing an X/Z location of featureR3 and X/Z location of featureR4 of a door on a fixture to establish an axisd relative to a design axisD;
- securing the door to the body/side;
- and
- sensing an X/Z location of featureR3 and X/Z location of featureR4 of the door as installed on the body/side and determining a difference between the X/Z location of featureR4 and an X dimension of featureR2 and the axisbs.
A method comprising:
- locating a first hole with a two-way sensor and a second hole with a four-way sensor on a body/side disposed on a pallet;
- locating a first pin with a two-way sensor and a second pin with a four-way sensor on a fixture supporting a door on the first and second pins on the fixture;
- correlating the locations of the first and second holes to the first and second pins;
- assembling the door to a vehicle body sub-assembly;
- and
- generating a warning signal at an in-station monitor to initiate immediate corrective action if the location of the holes is not within a predetermined tolerance relative to the location of the pins.
A door assembly method comprising:
- measuring at least two body/side locations in a body/side X/Z plane;
- measuring at least two door locations in a door X/Z plane while in a door hanging fixture;
- assembling the door to the body/side;
- measuring the at least two door locations in the door X/Z plane after assembly;
- and
- displaying a set of measurements on a monitor.
