Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor exposure test stand for holding weatherproof test pieces such as automobile parts.

[0002]

[Prior Art] JIS D0205 for weather resistance test of automobile parts
It is stipulated respectively in "Weather resistance test method for automobile parts", JIS Z2381 "Outdoor exposure test method general rule" and JIS K7219 "Plastic outdoor exposure test method general rule". In this test, the test piece is directly exposed to the outdoors, and the resistance to deterioration of parts in the natural environment is examined (referred to as the outdoor direct exposure test method). This resistance is judged by observing the decrease in strength and gloss and the change in color of the test piece directly exposed to the outdoors.

Further, this outdoor direct exposure test is conducted for a few months.
The test pieces are exposed to sunlight, wind, and rain for a long period of three years, and the resistance is examined with respect to weather resistance, light resistance, ozone resistance, and the like. In order to provide commonality or generality to the test environment, the direction of exposure is the southeast plane, the distance from the equipment installation surface (ground) to the bottom of the test piece is 500 mm or more, and the horizontal plane. The angle to is 30
It is set at 45 degrees or 45 degrees. In order to maintain this angle, when fixing the test piece to the hard one, only the upper part may be fixed and the lower part may be the free end.For soft ones such as cloth, the upper and lower parts should be fixed. It is decided to fix it.

As shown in FIG. 11, the outdoor direct exposure test apparatus determined by JIS D0205 supports a sample mounting frame 3 provided with a sample mounting bar 2 on a column 1 so that the sample mounting frame 3 is rotatable, and as shown in FIG. In the case of a soft test piece, the upper and lower ends of the test piece 4 are fixed by sandwiching them between the sample mounting bars 2 and the sample mounting frame 3 so that the angle changing arm 5 (Fig. 11) receives the sun rays. The test piece 4 is exposed to direct sunlight by changing the angle.

[0005]

In the conventional outdoor direct exposure test apparatus described above, when the upper and lower ends of a soft test piece such as a cloth are sandwiched between sample mounting bars and exposed to wind and rain for a long period of time, as shown in FIG. As shown in Fig. 4, the test piece 4 may bend like 4 ', and in some cases, one end of the test piece may come off like 4 ". In this way, the test piece bends or one end comes off. In this case, there is a problem in that the degree of sunlight contact is not normal and a highly accurate test cannot be performed.

Further, since this test is carried out for a long period of time, such as several months to three years, it is necessary to monitor the bending and disengagement of the test piece at all times, so that a large amount of waste is required, and the test piece is also consumed. If you leave it without noticing the bending or disconnection, you can not confirm at what time the bending or disconnection occurred, so you will have to repeat the test and it will take a lot of time and cost. There is. In addition, since the production may be started depending on the result of the test, there is a problem in productivity if the test takes a long time due to the re-execution of the test.

There are various test pieces of various sizes. Then, as shown in FIG. 11, a plurality of test pieces 4 are sandwiched and fixed between the long sample mounting bars 2. Therefore, as shown in FIG. 12, for example, when the distance L1 between the sample mounting bars 2 is determined in accordance with the maximum size of the test piece, it becomes impossible to sandwich both ends of the small size test piece. There is a problem that test pieces of various sizes cannot be sandwiched between the same sample mounting bars, and the test apparatus cannot be effectively used.

Some test pieces are short-term exposed and others are long-term exposed. Therefore, as shown in FIG. 11, when a test piece having a different exposure period is sandwiched between long sample mounting bars 2, in order to remove only the test piece exposed for a short period of time, the test piece is sandwiched by the sample mounting bars. All specimens must be removed and re-sandwiched for long-term exposure specimens. Therefore, there is a problem that extra work is required and the efficiency of the test is poor.

Further, in FIG. 11, when the test pieces 4 are sandwiched and fixed between all the sample mounting bars 2, the area receiving the wind pressure becomes L2 × L3, which is large, and the test pieces 4 having different thicknesses are used. When the test piece 4 is clamped by the long sample mounting bar 2, the test piece 4 cannot be clamped by a uniform clamping force.
The test piece 4 is easily pinched. When the test pieces are unclamped, the sample mounting bar 2 must be removed and re-clamped. Therefore, after all, the test pieces must also be unclamped, and all test pieces must be removed. There is a problem that it is necessary to redo the pinching of the piece.

The present invention strengthens the clamping of various test pieces, reduces the deflection and detachment of the test pieces, enables high-precision testing, and allows the test pieces to be partially attached and removed directly outdoors. (EN) Provided is an outdoor exposure test stand that improves the efficiency of the exposure test and further eliminates the need to repeat the test to improve the productivity.
