Description

[Detailed Description of the Invention] The present invention provides a calibration gauge that is an automatic one-part device for measuring the accuracy, etc. of an outer panel and an inner gland material (three parts), or is provided in a manufacturing process. It is used as a precision standard for equipment and jigs, and is used for models.It is related to the LA structure and its manufacturing method. , as shown in Figure 1,! IIfI! ll1 and the surface layer l is supported b from the honeycomb to the shelf side bi 1 and the bottom i2 and ll111II
The material 3 is made up of a "grt" grt and a structural part 4, and the resin containing Karasute Sotsu 1 and Karasuti 1 is applied to them. In order to maintain precision, it was made from about nine layers of glass cloth.The manufacturing method was as shown in Figure 2.
First, a weir 6 is made around the mask model 5 using a wooden frame or the like, and a gel coat resin is applied to the upper surface of the master model 5. After that.

A glass cloth is laminated thereon to form a surface layer l. Next, the lower frame 2 is fixed at the position where the necessary dimensions above the mask model 5 are secured via the support column 7 and the support frame 8, and as described above! !
A structure is formed by adhering the leg member 3 to the upper surface, which is the back surface of the surface layer 1, with a resin containing glass chops, glass tape, etc., and this is released from the mask model 5 and inverted to form an inspection gauge. 90However, since this conventional structure is made by laminating the surface layer 1,
Not only does it take a lot of man-hours, but the layering work is usually done about 9 times, that is, about 9 layers are piled up, and after 4 to 5 layers are laminated due to the temperature of ar-fatization, the process is carried out about 10 hours or a day later. There is a problem that it takes a lot of time, as it has to be done over two days, and the assembly of the leg members 3 of the structural part 4 requires the resin to be assembled in accordance with the dimensions of the back surface of the II surface layer 1 and the lower frame 2. Cut the pipe etc.

Since it must be bonded with resin, if the amount of resin used for bonding is large, there is a risk that dents may be formed in the surface layer l due to curing heat, etc., or that the entire leg member 3 may be distorted depending on the position where the leg member 3 is provided. Also, if the cutting dimensions of the single leg member 3 are not accurate, the surface layer 1 will also become distorted and grooved.

Not only is it difficult to ensure accuracy and requires skill,
There is also the problem that assembly requires a lot of man-hours, and in addition, the structural part 4
is composed of resin pipes and pigeon cams, but 1 surface layer 10
Since the back-up is rounded and a large number of leg members 3 and braces 9 are used, there is a problem that not only the weight increases unexpectedly, but also the material and processing costs increase, resulting in high cost.

In order to improve the above conventional drawbacks, as shown in Figure 3,
It is also possible to create a weir 12 around and above the master model 11 and foam the fat 13 to form the structure.
According to this method, the number of laminated layers of glass cloth that forms the surface layer 14 is about 3 (usually, and the working time for this can be greatly shortened, but the weir 12 is adjusted to the foaming pressure of the resin 13). It requires a large amount of man-hours to manufacture the weir 12, which must be rounded to be strong and airtight, and requires technology to control the injection amount of the resin 13, the mixing ratio with the foaming agent, temperature control, etc.
There is a problem that the quality control layer is difficult and troublesome, and when foaming appears to have finished on the surface of the s It m 13, post-foaming continues for a long time inside. If the structure, which is to be used as an inspection gauge, etc., is removed from the master model 11 too early, there is a risk that it will not only be distorted, but also that the surface layer 14 of the structure may be damaged if the single power generation power is too high. There is a problem in that the quality of the product is poor and the number of finishing steps increases.

In order to solve the above-mentioned conventional problems, the applicant has previously
According to Japanese Patent Application No. 178838/1983, which was applied to tbm, ``Gel coat resin is cured to form a surface layer s2J, and this back surface Kl
In addition to hardening the material ρ to form the surface layer, the structural part 24 made of a hard resin foam block is
A structure integrally formed on the back surface of the front WiNIz (see FIG. 4) and its manufacturing method are provided to improve workability.

The aim was to reduce manufacturing man-hours and rows, reduce manufacturing costs, and reduce weight. There are cases where the resin wire is not filled to the depths of the body structure, and the surface layer 2 of that part is
3VC cavities are likely to appear, and the effects of dimensional changes due to hardening and shrinkage of the surface layer resin after fabrication are large, and the structure is susceptible to buckling due to drop impact during use. Since the skeleton structure is lightweight, creep deformation may occur, but once this occurs, the lightweight structure will cause it to return to its original state, so it is desirable to prevent the creep deformation from occurring completely. b is attached to the base.

Therefore, in the present invention, without impairing the advantages of the previously applied structure, we have developed a structure that is affected by the hardening and shrinkage of the surface layer that occurs after the production of structures such as OSE calibration gauges and models, and by the drop impact during use. This prevents buckling deformation of the
The purpose is to completely prevent creep deformation caused by light and temperature (particularly warm in summer, etc.) during use and storage.

(not shown) etc., mark the resin rigid foam 34 easily (see FIG. 90), and cut it. The cutting method may be performed by using a mechanical saw or a heating wire, or in the case of hard styrene foam, an organic solvent may be placed between the material and the master model 41, and S-solution may be used. Next, a plurality of cut resin rigid foams are joined together using an epoxy resin to form a supporting frame body having a pointed main body part. (See Figure 9 (C)) In this case, if necessary, cut the surface layer a to smooth out the contact, or use a surface plate (not shown) to align the back surface.
After that, a weir 42 is placed around the master model 41 using a wooden frame or the like.
After applying the sheet wax 43 and the #Il antidepressant, a gel coat resin 311 mainly made of epoxy resin, which will become the surface 1631 of the surface layer a, is applied.

Further, according to #I2-1jllK of the present invention, the lower end peripheral edge and the vertical corner portion of the support frame made of a hard resin foam forming the main body of the structure are formed into an abbreviated shape made of a thin metal plate. Enclose it at a certain angle, and also on the @ side of the support frame.
Since the structural part was constructed by attaching a plate-shaped angle made of the same material that connects the angle attached to the Tm periphery of the support frame and the surface layer, the rigidity in the direction perpendicular to the surface layer can be increased. Therefore, it is possible to prevent the occurrence of gaps with respect to the normal surface, and also to prevent dents on the base surface due to buckling of the structure due to drop impact caused by carelessness during use. It was possible to prevent warping and damage to corners, etc.Furthermore, the support frame made of rigid resin foam and the angle made of thin metal plates, which make up the structural part, are lightweight and easy to use. 4 has the effect of preventing Cree-1 deformation by increasing the rigidity by reinforcing the angle.
