Abstract

An apparatus and a method for correcting a vehicle member, by which twisting or deflection of a vehicle member including a side member of the vehicle, may be corrected, may be disclosed, wherein the apparatus for correcting a vehicle member includes a base extending in a lengthwise direction thereof, and a plurality of correction units disposed on the base to be movable.

First claim

What is claimed is:

1. An apparatus for correcting a vehicle member, the apparatus comprising:
a base extending in a lengthwise direction thereof; and
a plurality of correction units disposed on the base to be movable;
wherein each of the plurality of correction units includes: a correction body disposed on the base and a clamp device disposed below the correction body; and
wherein each clamp device includes: a clamp body, two clamp arms pivotally disposed in the clamp body, and two clamp cylinders configured to individually drive the two clamp arms.

2. The apparatus of claim 1 , wherein the clamp body is connected to lower portions of the corresponding correction body.

3. The apparatus of claim 1 , wherein connection members are disposed in rods of the clamp cylinders, sliders are pivotally disposed in the connection members through pivot shafts, and the sliders are disposed to be movable along the clamp arms.

4. The apparatus of claim 3 , wherein each of the sliders has a guide boss, and a corresponding clamp arm has a guide groove by which the guide boss is guided.

5. The apparatus of claim 4 , further comprising:
slider guides configured to guide movements of the sliders.

6. The apparatus of claim 5 , wherein each of the sliders has a guide surface and each corresponding slider guide has a guide surface configured to guide the guide surface of the slider, and
wherein the guide surface of the slider guide includes a first guide surface configured to guide an upward movement of the slider and a second guide surface configured to guide a downward movement of the slider.

7. The apparatus of claim 1 , wherein each correction body has two symmetrically disposed correction cylinders.

8. The apparatus of claim 7 , wherein upper end portions of the correction cylinders are pivotally disposed in each corresponding correction body by the pivot shafts, pivot members are disposed at lower end portions of the correction cylinders, and the pivot members are pivotally connected to the corresponding clamp devices by the pivot shafts.
