Abstract

An apparatus for lifting and rotating a frame of a motor vehicle includes a rotisserie and a rotatably connected fixture that holds the motor vehicle frame during production. The fixture includes clamps extending from arms of the fixture and clamps extending from the front support for affixing the frame of the motor vehicle to the fixture. The fixture may further include a passive lock mechanism for engaging a side sill of the frame that includes a latch, a locking extension, a latch spring that holds the latch in engagement with the frame, and a pendulum that rotates relative to the fixture but remains oriented in a fixed location relative to horizontal. The latch may only be disengaged from the frame when the locking extension is aligned to be received by a slot in the pendulum when the fixture is rotated to the home location.

First claim

What is claimed is:

1. An apparatus for use in production of a motor vehicle to lift a frame of the motor vehicle and rotate the frame 360° about a longitudinal axis, comprising:
a rotisserie fixed to a floor of a facitilty for producing the motor vehicle, the rotisserie comprising a fixed vertical portion and an adjustable portion that may be vertically raised and lowered and rotated about the longitudinal axis;
a fixture connected to the adjustable portion of the rotisserie for holding the frame of the motor vehicle during production, the fixture being rotatable about the longitudinal axis, the fixture further comprising:
a single mounting plate attached to the adjustable portion of the rotisserie, the fixture being solely attached to the rotisserie by the mounting plate such that the fixture is mounted to the rotisserie in a cantilever fashion;
a support structure comprising a lateral support that connected to the mounting plate, first and second longitudinal arms having first ends connected to extending longitudinally from the lateral support, and a front support extending between second ends of the first and second longitudinal arms, wherein a first end of the front support is attached to the first longitudinal arm by a swivel ball joint and a second end of the front support is releasably connected to the second longitudinal arm;
first and second clamps extending from the first ends of the first and second longitudinal arms for affixing the frame of the motor vehicle to the support structure; and
third and fourth clamps extending from the front support for affixing the frame of the motor vehicle to the support structure, wherein the third and fourth clamps are engaged with the frame by inserting the swivel ball joint into a socket and sliding the third and fourth clamps into engagement with the frame.

2. The apparatus of claim 1 wherein the first and second clamps each comprise:
a rear supporting clamp body;
a side supporting clamp body; and
a slidable clamp assembly that is movable to engage the frame to secure the frame in the fixture and to disengage from the frame to release the frame for removal from the fixture.

3. The apparatus of claim 2 wherein the slidable clamp assembly further comprises:
an L-shaped clamp having a first end and a second end;
a latching pin for engaging and disengaging the slidable clamp assembly; and
wherein the latching pin is connected to the first end of the L-shaped clamp, and the second end of the L-shaped clamp contacts the frame to secure the frame to the fixture when engaged.

4. The apparatus of claim 1 wherein the third and fourth clamps are L-shaped and integral with the front support.

5. The apparatus of claim 1 wherein the fixture may be raised and lowered on the rotisserie.

6. The apparatus of claim 1 wherein the fixture is made of a material selected from the group that consists of aluminum, steel, and stainless steel.

7. The apparatus of claim 6 wherein portions of the first, second, third, and fourth clamps that engage the frame are made of plastic.
