ASSEMBLY LINE VEHICLE BODY POSITIONING
First Claim
1. A vehicle body assembly line adjustable locator assembly for use in an assembly station to assemble vehicle body formed metal parts to a partially assembled vehicle body, the locator assembly comprising:
- a plurality of locators each of which includes a locator member for mounting a locator head having a vertical rest surface for supporting the partially assembled vehicle body along a vertical axis, and at least a pair of the mounted locator heads each having a locator pin projecting upwardly from its vertical rest surface to provide horizontal positioning of the partially assembled vehicle body;
each of the locators including longitudinal X, sideways Y, and vertical Z actuators for driving the locator member thereof in longitudinal, sideways, and vertical directions with respect to the locator assembly; and
a control for the actuators for selectively controlling the vertical positioning of each locator member while allowing longitudinal and sideways movement thereof in a horizontal plane so positioning holes in the partially assembled vehicle body receive the locator pins upon relative vertical movement between the locator members and the partially assembled vehicle body and back drive the locator members having the locator pins horizontally as necessary as the vertical rest surfaces of the locator members move into supporting contact with the partially assembled vehicle body, and the control subsequently operating the locators as necessary to move the locator members and the partially assembled vehicle body supported thereby to the proper position for further assembly.

Abstract
A vehicle body assembly line locator assembly (16) includes locators (18) having locator pins (82) received by vehicle body positioning holes (84) upon upward movement to provide accurate positioning. As the locator pins (82) are moved upwardly and initially move into the vehicle body positioning holes (84), horizontal power actuators (50,58) are deactuated to permit back driving of the locator pins to permit full insertion. The upward movement is continued so that vertical rest surfaces (80) of locator heads (78) contact the vehicle body (20) and provide lifting thereof upwardly off a system conveyor, and the power actuators then move the vehicle body to the proper positioning for further assembly.

9. A vehicle body assembly line adjustable locator assembly for use in an assembly station to assemble vehicle body formed metal parts to a partially assembled vehicle body, the locator assembly comprising:
-
a plurality of locators each of which includes a locator member for mounting a locator head having a vertical rest surface for supporting the partially assembled vehicle body along a vertical axis, and the mounted locator heads each having a locator pin projecting upwardly from its vertical rest surface to provide horizontal positioning of the partially assembled vehicle body;
each of the locators including longitudinal X, sideways Y, and vertical Z actuators for driving the locator member thereof in longitudinal, sideways, and vertical directions with respect to the locator assembly;
the locator pin of each locator head having a clamp for clamping the partially assembled vehicle body against the associated vertical rest surface;
a control for the actuators for moving the locator member upwardly while allowing longitudinal and sideways movement thereof in a horizontal plane so positioning holes in the partially assembled vehicle body respectively receive the locator pins and through the locator pins back drive the locator members horizontally as necessary as the vertical rest surfaces of locator members move into supporting contact with the partially assembled vehicle body, the locator head of one of the locator members including locator pin for providing horizontal location of the partially assembled vehicle body in both longitudinal and sideways horizontal directions and the locator head of another of the locator members including a locator pin for providing horizontal location of the partially assembled vehicle body in one of the longitudinal and sideways horizontal directions, and the control subsequently moving each clamp to the clamped position to the clamped position the partially assembled vehicle body against the associated vertical rest surface and the control also operating the locators as necessary to move the locator members and the partially assembled vehicle body supported thereby to the proper position for further assembly.

10. A method for locating a partially assembled vehicle body at an assembly station of an assembly line for further assembly, the method comprising:
-
conveying the partially assembled vehicle body to the assembly station above locators thereof which have locator members that mount locator heads including vertical rest surfaces and at least a pair of which have upwardly projecting locator pins;
initially positioning the locator members by actuators of the locators in predetermined longitudinal X, sideways Y, and vertical Z positions;
providing relative vertical movement between the locator members and the partially assembled vehicle body while allowing longitudinal and sideways movement of the locator members in a horizontal plane so positioning holes in the partially assembled vehicle body receive the locator pins and back drive the locator members having the locator pins horizontally as necessary as the vertical rest surfaces of locator members move into supporting contact with the partially assembled vehicle body; and
subsequently moving the locator members as necessary to position the partially assembled vehicle body supported thereby to a predetermined position for the further assembly. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method for locating a partially assembled vehicle body at an assembly station of an assembly line for further assembly, the method comprising:
-
conveying the partially assembled vehicle body to the assembly station above locators thereof which have locator members mounting locator heads having vertical rest surfaces and upwardly projecting locator pins;
initially positioning the locator members by actuators of the locators in predetermined longitudinal X, sideways Y, and vertical Z positions;
moving the locator members upwardly toward the partially assembled vehicle body while allowing longitudinal and sideways movement of the locator members in a horizontal plane so positioning holes in the partially assembled vehicle body respectively receive the locator pins and back drive the locator members as necessary as the vertical rest surfaces of locator heads move into supporting contact with the partially assembled vehicle body; and
clamping the partially assembled vehicle body against at least some of the vertical rest surfaces of the locator heads and moving the locator members as necessary to position the partially assembled vehicle body supported thereby to a predetermined position for the further assembly.
