Abstract

A jig for aligning door hinges into a position at a predetermined mounting angle in an automatic system that automatically mounts door hinges to upper and lower seats on pillars of a vehicle body conveyed by a conveying unit. The jig may include a support frame, a first support part fixed to the support frame and supporting a hinge bracket of the door hinge, a pair of second support parts movably disposed at both sides of the first support part and respectively supporting both sides of a door bracket of the door hinge, and an actuating cylinder fixed to the support frame and connected with the second support parts.

First claim

What is claimed is:

1. A jig for aligning a door hinge into a position at a predetermined mounting angle, in an automatic system that automatically mounts door hinges to upper and lower seats on pillars of a vehicle body conveyed by a conveying unit, the jig comprising:
a support frame;
a first support part fixed to the support frame for supporting a hinge bracket of the door hinge;
a pair of second support parts movably disposed at both sides of the first support part for respectively supporting both sides of a door bracket of the door hinge;
actuating cylinders fixed to the support frame and connected with the second support parts; and
a clamper fixed to the support frame for clamping the hinge bracket by operation of a clamping cylinder.

2. The jig of claim 1 , wherein a pair of guide members for guiding both sides of the hinge bracket is included in the first support part.

3. The jig of claim 2 , wherein at least one tooling pin for aligning the hinge bracket is formed at the first support part.

4. The jig of claim 3 , wherein an approach sensor configured to sense whether the hinge bracket is seated is included in the first support part.

5. The jig of claim 1 , wherein each of the second support parts includes:
a mounting bracket fixed to an actuating rod of the actuating cylinder; and
a pair of guide plates facing each other at a predetermined distance and fixed to the mounting bracket, wherein the pair of guide plates is configured for fixing the respective side of the door bracket and for arranging the door hinge into the position at the predetermined mounting angle.

6. The jig of claim 5 , wherein upper portions of the pair of guide plates are smoothly curved away from each other.

7. A jig for aligning a door hinge into a position, in an automatic system that automatically mounts door hinges to upper and lower seats on pillars of a vehicle body conveyed by a conveying unit, the jig comprising:
a support frame;
a base member fixed to the support frame for supporting a hinge bracket of the door hinge;
a pair of supporting members disposed on the support frame to be movable toward or away from each other at both sides of the door hinge, and respectively supporting both sides of a door bracket of the door hinge;
actuating cylinders fixed to the base member and for connected with the supporting members; and for
a clamper fixed to the support frame for clamping the hinge bracket.

8. The jig of claim 7 , wherein a seating groove where to seat the hinge bracket of the door hinge is formed on the base member.

9. The jig of claim 7 , wherein fixing for grooves fixing the both sides of the door bracket are formed at the supporting members, respectively.

10. The jig of claim 7 , wherein the actuating cylinders are bidirectional cylinders.
