Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for assembling a long hollow object by fitting another long object into the inside thereof.

Conventionally, when assembling a long hollow object by fitting another long object into it, the fitting part was generally located at the back, making it difficult to center the object to be assembled, and it was often done by hand. Even in the case of mechanization, when assembling objects horizontally, it is necessary to grip the object at a position close to the end of the object to prevent the part that grips the object that fits inside from interfering with the hollow object outside. This caused the other end to sag, causing misalignment and making assembly difficult. Moreover, as mentioned above, since the fitting part of a long object is at the end of the stroke, it is necessary to insert the object quietly all the way to the end without any shock during assembly.

In addition, when assembling vertically to facilitate centering, a reversing device and a conveying device are required, and in order to prevent the device from falling over during conveyance, there are disadvantages such as a complicated mechanism and high equipment costs. was there. Furthermore, when assembling it, there was a drawback that it was easy to fall over if you just grabbed the ends to make it vertical.

The present invention provides a device that can smoothly and accurately assemble two long objects by placing them horizontally during transportation and vertically during assembly, even if there is a fitting part at the stroke end when assembling long objects. This is the purpose.

The assembly device of the present invention includes a gripping device capable of gripping an internal object, a support device capable of abutting and supporting one end of the internal object, and a gripping device De capable of gripping an external object fitted externally to the internal object. The present invention is characterized in that a frame including a gripping device movable in the fitting direction with the internal object is provided so as to be rotatable to a position where the internal body and the external object are perpendicular to each other.

An embodiment of the present invention will be described below with reference to the drawings.
