Description

{Manufacturing jig for Roof rack cross bar}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for fixing a roof rack side bar before machining, and more particularly, to a jig for fixing a roof rack side bar to a roof rack side bar in the form of a three- So that it is prevented from moving during high-speed processing, thereby improving the productivity of the roof rack side bar.

In general, passenger cars and other non-freight vehicles have limited internal space, so there is a limit to the load of cargo.

For this reason, a loop carrier as disclosed in Korean Patent Laid-Open Publication No. 10-1997-0038757 or the like is mounted on the upper surface of a roof panel of a vehicle to further secure a loading space.

The roof carrier includes a pair of roof racks installed longitudinally on both sides of the roof panel and a plurality of crossbars engaged between the roof racks. .

On the other hand, conventional roof racks are generally manufactured in a split type, and separately formed roof racks (main bodies), stents, covers and pads are assembled together. In addition, such a conventional split type roof rack can increase the degree of design freedom by fabricating the cover in various colors and shapes.

However, the conventional split roof rack is composed of relatively many parts of about ten kinds, and in particular, it takes a considerable time to assemble the products because the cover engagement is difficult for each of the front and rear ends of the main body and the stent, There was a problem of deterioration.

In order to solve the above problem, an integral roof rack has been proposed.

Since the conventional integrated roof rack is manufactured in a form including a roof rack side (body) and a stance and a cover function, it is composed of a relatively small number of parts, so that the parts are simplified compared to the conventional split roof rack,

However, the manufacturing method of a general roof rack side bar is made by aluminum extrusion and bending, and matching with a roof panel in the form of a three-dimensional free-form surface is incomplete by such a processing method. Therefore, in order to join the roof rack side bar to the roof panel, a certain cutting process is inevitably accompanied.

Conventional technology of a facility for processing a conventional roof rack side bar is composed of a bottom plate, a clamping unit, a roof rack side bar position fixing and a fixing part.

The clamping unit has a limited support force in a point-to-point contact from the top to the bottom. To increase the supporting force, it is necessary to use a large-capacity rotator. In addition, The defect rate is increased.

When the bearing capacity is weak, the productivity is deteriorated due to the trembling phenomenon at high speed processing.

Another method for increasing the supporting force is to increase the number of the clamping units, thereby wasting unnecessary energy and space because a plurality of units are installed in a limited space, and the number of the roof rack side bars that can be processed at one time is also reduced The productivity is lowered.

Another problem of the point contact method of the clamping unit is that it takes a considerable time to align the equipment and the product during the initial processing of the roof rack side bar, thereby lowering the overall processing efficiency.

Further, there is a problem that it takes much time to fix the roof rack side bar in a state where one side of the roof rack side bar is fixed and the fixing part is made from the upper direction to the lower side.

And since there is no function to detect the roof rack sidebar, productivity is reduced because it has limitations on processing by automatic program.
