Description

Chamfering device for cutting surface of sunroof rail {CHAMFERING DEVICE FOR CUTTING SURFACE OF SUNROOF RAIL}

The present invention relates to a processing device used for chamfering a cut surface of a sunroof rail.

A vehicle sunroof is a device installed on the roof of a vehicle to introduce external light or air into the vehicle. Among the sunroofs, some large sunroofs called panoramic sunroofs have a method of opening and closing by sliding forward and backward along the roof. For example, "Sliding structure of a panoramic sunroof for vehicles" of Publication No. 10-2013-0068542 discloses such a sliding opening and closing structure.

In the sliding type sunroof, a sunroof rail for guiding the movement of the glass may be installed on the roof of the vehicle. In general, the sunroof rail is arranged to extend forward and backward on the roof to support the glass from the bottom. For example, “roof rail of a panoramic sunroof” of Patent Publication No. 10-2010-0016981 discloses such a sunroof rail.

The sunroof rail has a predetermined cross-sectional shape and extends in the longitudinal direction. The cross-sectional shape is slightly different depending on the type or specification of each product, but most of the currently commonly used rails have similar cross-sectional shapes. Manufacturing of the sunroof rail may be performed in the order of manufacturing a primary linear product having a predetermined cross-sectional shape using aluminum or the like, and appropriately cutting out holes, shapes, etc. from the primary molded product. This rail fabrication process is now largely automated. For example, Patent Publication No. 10-2014-0110247 "Automotive sunroof rail processing device" discloses an automated processing device for manufacturing rails.

However, in the manufacturing process of the sunroof rail, there are still quite a few parts that are manually performed, and one of them is chamfering. Since the ends of the sunroof rail cut into a certain shape by a processing device are sharp, a separate chamfering process is performed. This chamfering process is performed depending on the manual work of a worker due to the complicated shape of the cut surface.

Against the above background, Patent Registration No. 10-2424635 entitled "Apparatus for chamfering a sunroof rail for vehicles" has proposed a processing apparatus capable of more effectively performing chamfering of a sunroof rail. The registered patent is configured to effectively automate the chamfering process despite the complex shape of the cut surface by pressing the cut surface of the rail through a punch block.

4 is an enlarged view of the chamfering unit shown in FIG. 1;

Referring to FIG. 4 , the chamfering unit 120 may include a first tool 121 that contacts the cutting surface 11 to perform chamfering. The first tool 121 may be supported by being fastened to the first tool holder 121a, and the first tool holder 121a may be coupled to the first driving motor 121b. The first driving motor 121b may be configured to rapidly reciprocate or vibrate the first tool 121 .

Similar to the above, the chamfering unit 120 may include a second tool 122 arranged to correspond vertically with the first tool 121 . The second tool 122 may be fastened to and supported by the second tool holder 122a, and the first tool holder 121a may be coupled to the second driving motor 122b. The second tool 122 and the like may be formed similarly to the first tool 121 and the like, except that the arrangement position thereof is different from that of the first tool 121 .

The first tool 121 may have a substantially bar shape and may extend in the longitudinal direction. The first tool 121 is a part that contacts the sunroof rail 10 to perform chamfering, and is preferably formed to have a predetermined thickness and sufficient rigidity. A polishing surface 121c may be formed on the upper and/or lower surface of the first tool 121 to contact the cutting surface 11 to perform chamfering. Appropriate patterns, patterns, materials, and roughness for chamfering may be formed on the polishing surface 121c.

That is, the first tool 121 may be disposed inclined downward to a certain degree toward the cut surface 11 of the sunroof rail 10 or the first setting part 111 . For example, the first tool 121 may be disposed inclined at an angle of approximately 10 to 30 degrees with respect to the horizontal direction. If the inclination of the first tool 121 is too small, the approach guiding effect through the inclination may be insufficient, and if the inclination is too large, contact with the cutting surface 11 may not be smooth. The inclined first tool 121 can more smoothly approach and enter between the cut surfaces 11 of the sunroof rail 10 having a complex shape.

As described above, the chamfering process may be performed in a state in which the first tool 121 is disposed inclined downward. The first tool 121 approaches the sunroof rail 10 in a downwardly inclined state and can be inserted into the end of the sunroof rail 10 to a predetermined extent, and is reciprocated or vibrated in a downwardly inclined state to cut the surface ( 11) may be formed to chamfer processing. This method has an effective advantage in improving the processing speed by quickly setting the working position while properly securing the processing quality of the cut surface 11 through sufficient contact surfaces.

Meanwhile, the second tool 122 and the like may be formed substantially similar to the above-described first tool 121 and the like. A polishing surface 121c may be formed on an upper and/or lower surface of the second tool 122, and the second tool holder 122a may fix the second tool 122 to the second driving motor 122b. And, the second driving motor 122b may be formed to reciprocate or vibrate the second tool 122.

In addition, the second tool 122 may be disposed below the first tool 121 and inclined upward at a predetermined angle with respect to the horizontal direction to correspond to the first tool 121 . That is, the second tool 122 may be disposed inclined upward by a certain degree toward the cut surface 11 of the sunroof rail 10 or the first setting part 111 . This is a similar purpose as described above through the first tool 121.

If necessary, the first and second tools 121 and 122 may be installed to rotate to a predetermined degree around the first and second tilting axes R1 and R2, respectively. In the case of this embodiment, the first and second tools 121 and 122 are mounted on the first and second driving motors 121b and 122b having the first and second tilting axes R1 and R2, respectively, and the first and second tilting axes A case in which rotation is possible around (R1, R2) is exemplified. Also, in this case, the first and second tools 121 and 122 may be elastically supported in a direction of rotation about the first and second tilting axes R1 and R2, respectively. For example, rotation of the first and second tools 121 and 122 may be elastically supported through an air cylinder.

In the above case, the first and second tools 121 and 122 are rotated to a predetermined extent from their initial positions around the first and second tilting axes R1 and R2, so that the entry into the cutting surface 11 can be made more smoothly. . That is, before the first and second tools 121 and 122 enter the cutting surface 11, the first and second tools 121 and 122 are rotated to a predetermined degree in a direction in which they become closer to each other from the initial position, and then the first and second tools 121 and 122 The tools 121 and 122 may enter the end of the sunroof rail 10 and come into contact with the cut surface 11 . Accordingly, the first and second tools 121 and 122 can be approached and set to appropriate working positions despite the complicated shape of the cutting surface 11 or the narrow space. In addition, the first and second tools 121 and 122 are elastically supported in the rotation direction, respectively, so that the first and second tools 121 and 122 can maintain close contact with the cutting surface 11 during processing. By reciprocating or vibrating the first and second tools 121 and 122 in close contact, the processing quality and speed can be further improved.
