Description

Clamping Device for Bumper Beams {CLAMPING APPARATUS FOR BUMPER BEAM}

The present invention relates to a clamping device for a bumper beam, and more particularly, a locator is rotatably installed with respect to a jig base, and the locator is hinged through a separate curvature adjusting cylinder to correspond to each clamping surface of the locator and the clamper. The present invention relates to a clamping device for a bumper beam that can cope with the curvature of the bumper beam.

In general, the clamping device is a device for fixing the material so that it does not move during the cutting operations, such as cutting, sheet metal, welding, etc., the clamping force or the clamping part is different for each machining operation and the structure of the clamping device is also different Do.

Among these clamping devices, as shown in FIG. 1, an example of the clamping device 110 for assembling the vehicle bumper beam 100 and the stage 200 may be installed at a plurality of locations on the jig base 101. And a bumper beam 100 on which the locator 103 is seated, a clamping cylinder 105 hinged to one side of the locator 103 to operate by pneumatic or hydraulic pressure, and one side to the other side of the locator 103. A clamper fixed by a hinge and having a rear end hinged to the front end of the actuating rod 107 of the clamping cylinder 105 is hinged according to the reciprocating motion of the actuating rod 107 to clamp or unclamp the bumper beam 100 ( 109).

That is, when the operating pressure is supplied to the clamping cylinder 105, the tip of the clamper 109 is lowered by the hinge operation while the operation rod 107 is raised, and the clamper 109 is seated on the locator 103. The bumper beam 100 is regulated and fixed, thereby performing a post process such as welding.

However, in the conventional bumper beam clamping device 110 as described above, the curvature R of each bumper beam 100 regulated thereto is different, and the locator 103 for each curvature R of the bumper beam 100 is different. The inclination of each clamping surface of the and the clamper 109 must be made differently, and thus it is difficult to be used in common, and thus, there is a disadvantage that only the clamping device must be manufactured.

That is, when the bumper beam 100 having different curvature R specifications is supplied and regulated to the conventional bumper beam clamping device 110, as shown in FIG. 2, the curvature of the regulation surface of the bumper beam 100 is regulated. (R) and inclinations of the clamping surfaces of the locator 103 and the clamper 109 corresponding thereto are different, and the clamping surface of the bumper beam 100 is partially formed by the clamping surfaces of the locator 103 and the clamper 109. One side (P) of the regulatory surface has the disadvantage of causing damage such as being taken.

Therefore, the present invention was invented to solve the above-mentioned disadvantages, and the problem to be solved by the present invention is to install the locator rotatably with respect to the jig base, the locator is hinged through a separate curvature adjustment cylinder It is to provide a clamping device for the bumper beam can be shared by operating so that each clamping surface of the locator and the clamper can correspond to the curvature of the bumper beam.

The bumper beam clamping device of the present invention for realizing the technical problem as described above, the locator is installed on the jig base so that the bumper beam is seated at a plurality of places on the jig base, the clamping is hinged to one side of the locator One side is hinged to the cylinder and the other side of the locator, the rear end is hinged to the operation rod front end of the clamping cylinder is hinged according to the reciprocating motion of the operation rod clamping or unclamping the control surface of the bumper beam In the clamping device for a bumper beam consisting of,

The locator has one side thereof mounted on the jig base through a hinge unit to be rotatably installed with respect to the jig base, and on the jig base, a curvature adjusting cylinder is hinged to a side of the locator hinged to the side of the locator. It is characterized by.

The hinge unit includes a front and rear hinge plate fixed to the front and rear ends of the jig base, respectively; It characterized in that the front and rear hinge plate and the hinge pin is installed to penetrate one side of the locator in the front and rear direction.

The curvature adjusting cylinder is characterized in that one side is hinged through a hinge bracket on the jig base.

The curvature adjusting cylinder is characterized by comprising a pneumatic cylinder whose working pressure is pneumatic.

According to the clamping device for a bumper beam of the present invention made as described above, the locator is rotatably installed with respect to the jig base, and the locator is hinged through a separate curvature adjusting cylinder so that the respective clamping surfaces of the locator and the clamper correspond to each other. By making it possible to cope with the curvature of the bumper beam, there is an advantage that it can be shared, thereby preventing damage such as one side of the restriction surface of the bumper beam being taken by each clamping surface of the locator and the clamper.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described in detail.
