Abstract

A part correcting device for an automobile part may include a body in which the part is disposed, a hydraulic apparatus which presses and fixes one side of the part disposed in the body, a warpage correcting apparatus which corrects a warpage of the part by rotating the other side of the part left or right while fixing the other side of the part disposed in the body, and a deformation correcting apparatus which corrects an angle of the part by pressing flanges formed on both sides of the part downwardly while fixing the flanges.

First claim

What is claimed is:

1. A part correcting device for an automobile part, comprising:
a body in which the automobile part is disposed, the automobile part comprising a first side a and a second side located at opposite ends of a length of the automobile part with flanges running along both sides of the length and connecting the first and second sides of the automobile part;
a hydraulic apparatus configured to press and fix the first side of the automobile part disposed on the body;
a warpage correcting apparatus configured to rotate the second side of the automobile part left or right with respect to the length of the automobile part while fixing the second side of the automobile part disposed in the body so as to correct a warpage of the automobile part; and
a deformation correcting apparatus configured to press the flanges formed on both sides of the automobile part downwardly while fixing the flanges so as to correct an angle of the automobile part
wherein the hydraulic apparatus includes a support member which is fixed to one side of an upper surface of the body by a plurality of guide bars, a first hydraulic cylinder disposed on an upper surface of the support member, and a first fixing member which presses and fixes the first side of the automobile part disposed in the body while descending by the first hydraulic cylinder.

2. The part correcting device for an automobile part of claim 1 , wherein the first fixing member is provided with a guide plate and the guide plate is slidably coupled with the plurality of the guide bars to make ends of the guide plate correspond to the guide bars.

3. The part correcting device for an automobile part of claim 2 , wherein a bottom surface of the guide plate is provided with a second fixing member and the second fixing member is configured to press and fix the first side of the automobile part together with the first fixing member.

4. The part correcting device for an automobile part of claim 1 , wherein one side of the upper surface of the body is provided with a support which supports a bottom surface of the first side of the automobile part.

5. The part correcting device for an automobile part of claim 1 , wherein the warpage correcting apparatus includes a warpage correcting body which is disposed on an other side of an upper surface of the body with respect to the hydraulic apparatus, a warpage correcting member which is disposed on one surface of the warpage correcting body corresponding to the second side of the automobile part and corrects the warpage by rotating the automobile part left or right with respect to the length of the automobile part while fixing the second side of the automobile part, and a rotating member which is disposed on an other surface of the warpage correcting body with respect to the one surface and is configured to rotate the warpage correcting member left or right with respect to the length of the automobile part.

6. The part correcting device for an automobile part of claim 5 , wherein the warpage correcting member includes a rotating plate which is disposed on the one surface of the warpage correcting body, a support piece which is disposed on a lower portion of one surface of the rotating plate and supports the second side of the automobile part, and a second hydraulic cylinder which is disposed on an upper portion of the one surface of the rotating plate and is configured to press and fix the second side of the automobile part supported by the support piece.

7. The part correcting device for an automobile part of claim 5 , wherein the rotating member includes a rotating body which is disposed on the other surface of the warpage correcting body, a rotating bar which has one end coupled with the rotating plate through the correcting body and the other end inserted in the rotating body, a pinion which is coupled with the other end of the rotating bar, a rack gear which is meshed with the pinion and is configured to rotate the pinion at a time of straight movement, and a third hydraulic cylinder which is configured to straightly advance or retreat the rack gear.

8. The part correcting device for an automobile part of claim 1 , wherein the deformation correcting apparatus includes a deformation correcting body which is disposed between the hydraulic apparatus and the warpage correcting apparatus and has a guide hole substantially vertically disposed on a side thereof, a deformation correcting member which is provided with a fixing piece holding and fixing the flanges of the automobile part and a guide piece movably coupled with the guide hole of the deformation correcting body to press the flanges of the part so as to correct the angle of the automobile part, and a fourth hydraulic cylinder which descends the deformation correcting member along the guide hole.

9. The part correcting device for an automobile part of claim 8 , wherein the guide hole is formed in a curved form.

10. The part correcting device for an automobile part of claim 1 , wherein the deformation correcting apparatus is mounted between the hydraulic apparatus and the warpage correcting apparatus.
