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 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,
wherein measurement devices configured to measure the vehicle member are disposed in the clamp devices, and
wherein each of the measurement devices includes a probe disposed to be movable vertically while passing through the corresponding clamp device, and a linear encoder disposed at an upper end portion of the probe.

2. A method for correcting the vehicle member by use of the apparatus claimed in claim 1 , 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.

3. The method of claim 2 , further including:
measuring the 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.
