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.

Claims

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.

2. The apparatus of claim 1, wherein each of the correction units includes:

a correction body disposed in the base; and

a clamp device disposed below the correction body.

3. The apparatus of claim 2, wherein the 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.

4. The apparatus of claim 3, wherein the clamp body is connected to lower portions of the correction body, and one of the two clamp arms is disposed in the clamp body to be movable.

5. The apparatus of claim 3, 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.

6. The apparatus of claim 5, 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.

7. The apparatus of claim 6, further comprising:

slider guides configured to guide movements of the sliders.

8. The apparatus of claim 7, wherein each of the slider has a guide surface and a 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.

9. The apparatus of claim 2, wherein the correction body has two symmetrically disposed correction cylinders.

10. The apparatus of claim 9, wherein upper end portions of the correction cylinders are pivotally disposed in the correction bodies 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 clamp devices by the pivot shafts.

11. 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 a first predetermined number of the plurality of correction units have clamp devices configured to clamp the vehicle member, and

wherein a second predetermined number of the plurality of correction units have clamp devices configured to clamp the vehicle member, and correction cylinders configured to correct the vehicle member clamped by the clamp devices.

12. The apparatus of claim 11, wherein measurement devices configured to measure the vehicle member are disposed in the clamp devices.

13. A method for correcting a vehicle member by use of the apparatus claimed in claim 12, the method comprising:

introducing the vehicle member into the plurality of correction units;

primarily clamping the vehicle member;

measuring the primarily clamped vehicle member by the measurement device;

determining a success or a failure by comparing a value measured by the measurement device with a predetermined value; and

when the measured value corresponds to the failure, correcting the vehicle member after secondarily clamping the vehicle member.

14. The method of claim 13, further including:

measuring a value of the vehicle member after the vehicle member is corrected; and

comparing the value measured by the measurement device with the predetermined value and when the measured value corresponds to the success, unclamping and discharging the vehicle member.
