The methods and apparatuses of the present invention have other features and advantages which will be apparent from or are set forth in more detail in the accompanying drawings, which are incorporated herein, and the following Detailed Description, which together serve to explain certain principles of the present invention.
Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
A part correcting device for an automobile part according to exemplary embodiments of the present invention is an apparatus which fixes one end of a part disposed in a body by a hydraulic apparatus while fixing the other end of the part by a warpage correcting apparatus, rotates the part left or right, or clockwise/counter-clockwise to correct warpage, and corrects a deformed angle by fixing and pressing flanges disposed at both sides of the part by a deformation correcting apparatus.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that they can be easily practiced by those skilled in the art to which the present invention pertains. However, the present invention may be modified in various different ways and is not limited to the embodiments provided in the present description. In the accompanying drawings, portions unrelated to the description will be omitted in order to obviously describe the present invention, and similar reference numerals will be used to describe similar portions throughout the present specification.
As illustrated in
The body 100 is provided with the hydraulic apparatus 200, the warpage correcting apparatus 300, and the deformation correcting apparatus 400 which fix the disposed part 10 and corrects the warpage and the deformation, while disposing the part 10 on an upper surface of the body 100.
In this configuration, as the part 10 disclosed in the exemplary embodiments of the present invention, a center pillar of an automobile part is described as one example and the hydraulic apparatus 200, the warpage correcting apparatus 300, and the deformation correcting apparatus 400 are disposed on the upper surface of the body 100 to fix the center pillar and correct the warpage and the deformation.
Further, one side of the upper surface of the body 100 is provided with a support 110 for supporting one side of the part 10 and the upper surface of the support 110 is provided in a similar or the same form as a bottom form of the part 10 and includes a synthetic resin having elasticity disposed on the upper surface thereof. Therefore, the support 110 stably supports the bottom surface of the part 10.
As illustrated in
Meanwhile, the first fixing member 230 is provided with a guide plate 240 and the guide plate 240 is slidably coupled with the guide bars 211 so as to make ends of the guide plate 240 correspond to the guide bars 211, such that the first fixing member 230 dose not move in any directions other than slidably moving vertically or substantially vertically.
Meanwhile, a bottom surface of the guide plate 240 is provided with a second fixing member 250 and the second fixing member 250 presses and fixes one side of the part 10 along with the first fixing member 230 to increase a fixing force to the part 10.
When the so configured hydraulic apparatus 200 applies an oil pressure to the hydraulic cylinder 220, the first fixing member 230 descends along with the guide plate 240 while a piston rod of the hydraulic cylinder 220 is drawn out downwardly. In this case, the first and second fixing members 230 and 250 vertically descend along the guide bar 211 by the guide plate 240 to press and fix one side of the part 10 disposed on the support 110. Therefore, the hydraulic apparatus 200 presses and fixes the part 10 in a two-step manner by the first and second fixing members 230 and 250, thereby obtaining the more stable fixing force.
As illustrated in
Referring to
In other words, when the warpage correcting member 320 presses and fixes the other side of the part 10 supported to the support piece 322 by the second hydraulic cylinder 323 and rotates the rotating plate 321 in a direction opposite to a warpage direction of the part 10 in this state, the warpage correcting member 320 corrects the warpage while rotating the other side of the part 10 along with the rotating plate 321.
Meanwhile, the rotating plate 321 of the warpage correcting member 320 may be further provided with a deformation correcting apparatus 400 to be described below, and therefore may correct deformation such as an angle by pressing the flange or flanges of the part 10 fixed to the warpage correcting member 320.
Typically, a deformation correcting apparatus is difficult to be closely mounted to the warpage correcting member 320, such that it is difficult to correct the deformation of the other side of the part 10 close to the warpage correcting member 320. To solve the above problems, the rotating plate 321 of the warpage correcting member 320 is provided with the deformation correcting apparatus 400 to be able to correct an angle by pressing the flanges disposed on the other side of the part 10.
Referring to
That is, when the rack gear 334 is advanced by the third hydraulic cylinder 335, the rotating member 330 rotates the pinion 333 by the rack gear 334 and rotates the rotating plate 321 by rotating the rotating bar 332 together with the rotation of the pinion 333. Therefore, when the advance distance of the rack gear 334 is adjusted by the third hydraulic cylinder 335, the rotating member 330 may adjust the rotating angle of the rotating plate 321, thereby correcting the warpage of the part 10.
The so configured warpage correcting apparatus 300 corrects the warpage of the part 10 by rotating the warpage correcting member 320 left or right, or clockwise/counter-clockwise by using the rotating member 330, while fixing the other side of the part 10 by using the warpage correcting member 320 fixed to the warpage correcting body 310.
As illustrated in
That is, the deformation correcting apparatus 400 includes a deformation correcting body 410 which is mounted in the body 100 between the hydraulic apparatus 200 and the warpage correcting apparatus 300 and is provided with a guide hole 411 substantially vertically disposed at a side thereof, a deformation correcting member 420 which is provided with a fixing piece 421 holding and fixing the flange 11 of the part 10 and a guide piece 422 movably coupled with the guide hole 411 of the deformation correcting body 410 to press the flange 11 of the part 10 so as to correct an angle, and a fourth hydraulic cylinder 430 which descends the deformation correcting member 420 along the guide hole 411.
In this configuration, the fixing piece 421 holds and fixes the flange 11 of the part 10 by using a pressing plate 421b which is press-fitted in the upper surface of the support plate 421a by bolt tightening. That is, when the bolt is tightened in the state in which the flange 11 is inserted between the support plate 421a and the pressing plate 421b, the fixing piece 421 holds and fixes the flange 11 by press-fitting the support plate 421a in the pressing plate 421b.
Meanwhile, according to the exemplary embodiments of the present invention, the support plate 421a is manually press-fitted in the pressing plate 421b by a bolt; but the support plate 421a and the pressing plate 421b may be implemented to be automatically press-fitted by the hydraulic cylinder or a motor according to various other exemplary embodiments of the present invention.
Meanwhile, the guide hole 411 is formed to be vertically curved, such that the deformation correcting member 420 descends inwardly from the outside along the curved guide hole 411 to press the flange 11 folded by a predetermined angle inwardly from below, thereby increasing a correcting force.
When the so configured deformation correcting apparatus 400 holds and fixes the deformed flange 11 of the part 10 to the deformation correcting member 420 and then descends the deformation correcting member 420 through the fourth hydraulic cylinder 430, the deformation correcting member 420 presses the flange 11 of the part 10 while descending along the guide hole 411 of the deformation correcting body 410, such that the deformed part 10 may be corrected to be leveled and the marketability and the precision of the part 10 may increase.
Hereinafter, a method for correcting a part correcting device for an automobile part according to the exemplary embodiments of the present invention will be described below. That is, as illustrated in
As illustrated in
When the disposing (S10) is completed, the fixing of the part 10 (S20) is performed. Referring to
When the fixing of the part 10 is completed, the correcting of the warpage of the part 10 (S30) is performed. In the correcting of the warpage (S30), the warpage correcting member 320 rotates in a direction opposite to the warpage direction of the part 10 by the rotating member 330 of the warpage correcting apparatus, and therefore the part 10 is corrected at the same angle as one side of the part 10 while the other side of the part 10 rotates together with the warpage correcting member 320, thereby correcting the warpage of the part 10.
When the warpage correction of the part 10 is completed, the correcting of the deformation of the part 10 (S40) is performed. In the correcting of the deformation (S40), when the deformation correcting member 420 descends by the fourth hydraulic cylinder 430, the deformation correcting member 420 presses the flange 11 of the part 10 downwardly while descending along the guide hole 411 of the deformation correcting body 410, such that the part deformed at the predetermined angle is corrected to be leveled.
The method for correcting an automobile part according to the exemplary embodiments of the present invention corrects the warpage and the deformation which occurs during the manufacturing of the part, thereby increasing the precision and marketability of the part.
As set forth above, according to the exemplary embodiments of the present invention, it is possible to accurately correct the warpage and the deformation of the automobile part by using the part correcting device and improve the assembling performance and the marketability of the automobile part.
