Description

The present invention relates to a jig capable of easily inspecting the shape accuracy of a hollow portion of a hollow molded article.
The jig is an inspection tool used to measure the dimensional accuracy of a jig, that is, a workpiece.

  In order to measure the dimensional accuracy of cavities of chemical moldings such as urethane resin and other foamed synthetic resins and rubber foams, a fixed size jig is applied to each part of the target product. The difference from the inspection jig is measured.

  A large measuring jig is required to measure the cavity of a cushion body used in automobiles, vehicles, furniture, etc. with an inspection jig, but conventional inspection jigs have a cross-shaped groove on a plywood board, etc. Was cut into two opaque plates, combined, and fixed in a groove, and the gap between the outer periphery of the plate and the product was measured.

  However, there is a precision limit due to the size of the base plate or the upper three-dimensional structure and its warpage, and the three-dimensional plate to be inserted into the groove is opaque. There was a disadvantage that the contact state was not visible and the dimensional accuracy measurement of a large molded product was impossible or very difficult.

  The present invention is a structure in which a plurality of transparent hard resin plates are combined and combined so that they do not move when they are combined in a groove on the top so that they do not move and are combined in a plane so that they do not move. By using this inspection jig, the dimensional accuracy of each part of a large cavity can be measured. Also, the combination member can be disassembled for easy storage.

  Furthermore, the size and shape of the object can be adjusted by fitting multiple substrates to which similar transparent measurement plates combined in the vertical and horizontal directions are fitted, and by changing the shape of the transparent measurement plate depending on the size and deformation of the target measurement object. It is possible to make an inspection jig that can be measured accordingly.
