Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an assembling jig used in a process of assembling an outer panel component having a curvature such as a quarter panel which is an automobile body component.

[0002]

[Prior Art]

 Among automobile body parts, side panels such as quarter panels and quarter inner panels are usually assembled as side panel assemblies and then the entire body is assembled.

In order to assemble the side panel assembly, for the reason of the assembly work, a method of placing the outer plate component downward and arranging the inner plate component on the outer plate component is adopted as shown in FIG.

However, since the outer plate component is generally composed of a curved surface having a large curvature and lacks in shape-freezing property, an appropriate receiving surface is provided to support sagging of the surface and the surface is lifted. On the other hand, it is necessary to prevent these by providing left and right restrictions on both ends in the bending direction.

Therefore, in a jig for assembling the outer plate component having the curvature of the automobile body and the inner plate component, conventionally, as shown in FIG. A reference receiving block 1 having a receiving surface 1a for supporting the surface in the vertical direction and a guide gauge 2 for restricting the lateral (curving direction) position of the outer plate component 3 by contacting the flange 3a of the terminal is provided. is doing.

[0006]

[Problems to be solved by the device]

 However, since the outer plate component 3 alone has a low overall rigidity, the mounting relationship of the reference receiving block 1 must be finely adjusted in order to make the curvature of the surface the curvature determined by design. This requires a lot of man-hours because it tends to be repeated trial and error.

Further, it must be taken into consideration that the surface curvature of the outer plate component varies due to press working. In this case, the position of the reference receiving block 1 is fixed on the basis of the average value of the pressed product, but the surface curvature after assembly changes according to the variation of the pressed product. Therefore, with such a jig, it is difficult to fix the surface curvature of the outer plate component at a constant curvature determined by design.

The present invention has been made to solve the above-mentioned problems, abolishes the fine adjustment of the mounting relationship of the reference receiving block 1, and makes the surface curvature of the outer plate component constant at the curvature determined by design. It is intended to be fixed to.

[0009]

[Means for solving problems]

 In order to achieve the above-mentioned object, the present invention is a jig for assembling an outer plate component having a curvature of an automobile body and an inner plate component and having a receiving surface for supporting both ends of the outer plate component in the bending direction. A block, an intermediate receiving block having a receiving surface for supporting the middle of the outer plate component in the bending direction, a pressing means for pressing one end of the outer plate component in the bending direction in a direction substantially parallel to the receiving surface of the reference receiving block, A jig for assembling an automobile body part, which comprises a pressing force adjusting means for adjusting the pressing force of the pressing means.

[0010]

[Action]

 When an outer plate component and an inner plate component are set in such an assembly jig, even if the surface curvature of the outer plate component is not the curvature determined by the design, the pressing force adjusting means pushes it. The pressure adjusting pressure means presses one end of the outer plate part in the bending direction in a direction substantially parallel to the receiving surface of the reference receiving block, so that the middle part of the outer plate part in the bending direction moves downward, and When hitting the receiving surface supported by the intermediate receiving block at a position with a defined curvature, the surface curvature of the outer plate component will be the curvature defined by design.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the present invention, in which a reference receiving block 1, an intermediate receiving block 6, a holding block 7, an air cylinder 8 and an air pressure regulator 9 are arranged on a jig surface plate 5. To do.

First, the reference receiving block 1 comes into contact with the receiving surface 1 a that supports both ends of the outer panel component 3 having a curvature in the bending direction and the flange 3 a of the outer panel component 3, and the lateral direction of the outer panel component 3 ( It has a guide gauge 2 that regulates the (curving direction) position. Here, the receiving surface 1 a is formed into a surface shape determined by the design of the outer plate component 3. Further, the guide gauge 2 has its upper end inclined outward and is fixed to the seat surface 1b provided on the reference receiving block 1 so as to guide the outer plate component 3 to a substantially regular position.

Next, the intermediate receiving block 6 is a receiving surface whose position is adjusted in advance so as to support the middle of the outer plate component 3 in the bending direction when the outer plate component 3 has a curvature determined by design. 6a. In addition, in order to facilitate the height adjustment of the receiving surface 6a, only the receiving surface 6a is separable at the upper end of the intermediate receiving block 6, and the receiving surface 6a is formed into a predetermined surface shape.

Further, the pressing block 7 has a pressing surface 7 a for pressing the flange 3 a at one end in the bending direction of the outer plate component 3 at one end, and the shaft 10 arranged on the wall surface of the reference receiving block 1 It is rotatably supported around the center, and the other end is connected to the air cylinder 8 by a shaft 11. The pressing surface 7a stands by outside the guide gauge 2 before the outer plate component 3 and the inner plate component 4 are loaded into the jig, and is rotated after the loading to rotate the flange 3a to the reference receiving block 1. It is pressed in a direction substantially parallel to the receiving surface 1a.

This operation is performed by transmitting the thrust generated by feeding air to the air cylinder 8 to the pressing block 7 connected by the shaft 11 and rotating the shaft 10 about the fulcrum. The pressing block 7 and the air cylinder 8 constitute pressing means for the outer plate component 3.

The air pressure supplied to the air cylinder 8 is such that the flange 3a of the outer plate component 3 is not deformed, and the curved surface of the outer plate component 3 receives the intermediate portion in the bending direction. , And is adjusted in advance via the air pressure regulator 9 so as to have a curvature determined by design, and is kept constant.

[0017]

[Effect of the device]

 According to the jig of the present invention having the above-mentioned configuration, when the outer plate component 3 and the inner plate component 4 are set in the jig, the surface curvature of the outer plate component 3 is springed back and the shape is extended to the whole. However, by pressing the flange 3a with the pressing surface 7a of the pressing block 7, the outer plate component 3 can be corrected to have a curvature determined by design.

Therefore, after the outer plate component 3 and the inner plate component 4 are positioned by the jig of the present invention, the two components are integrated by spot welding or the like in the jig to reduce the surface curvature of the outer plate component 3. It can be fixed at a curvature determined by design. Further, since the pressing force of the pressing surface 7a of the pressing block 7 is through the air pressure, even if there is some variation in the surface curvature of the outer plate component 3, other quality problems do not occur and the design is It is possible to obtain a fixed song ratio.
