Background technique

The environmental chamber is actually a kind of testing equipment that reasonably simulates indoor environmental conditions, and is widely used in material-level testing. At present, in this type of test, for material-level tests (surface properties, hardness, friction performance, etc.) that require immersion in an environmental chamber (temperature, humidity, vacuum), the environmental chamber is generally closed first, and then the environmental immersion is performed before testing. , the test of a single material is usually within 20 minutes. In order to ensure the soaking effect, the standard soaking time is usually as long as 2-3 hours. After the test of a single material is completed, it is necessary to open the hatch, take out the sample, put in a new sample, and then start again Environmental chamber immersion. However, the immersion treatment of the environmental chamber is a serial mode of immersion-test-soak-test... The environmental immersion takes up a lot of test time and the test efficiency is low.

The sample tray is aligned with the discharge opening, and the free end of the push mechanism is against the side of the bottommost sample tray away from the discharge opening. After soaking the samples in a uniform temperature and humidity, the samples on the test platform can be tested: the free end of the push mechanism is extended to push the lowermost sample from the discharge port to the test platform, and the clamping mechanism will The sample tray on the test platform is clamped. After the sample test is completed, the clamping mechanism is released, the free end of the push mechanism is retracted, the stacked sample trays fall, and the push mechanism again touches the side of the bottom sample tray. After the sample plate is pushed to the specified position on the test platform, it is clamped by the clamping mechanism and tested. By repeating this, the material-level test can be carried out on the samples one by one. During the test, there is no need to open the environmental chamber, avoiding repeated soaking, improving the efficiency of sample testing and saving testing time.

Optionally, the sample disk is made of magnetic material, and the clamping mechanism includes an electromagnet, and the electromagnet is installed on the top surface of the test platform.

When the stopper is directly in contact with the pressing tablet, the pressing tablet will move down directly to form overpressure, which will easily crush the sample. After the compression spring is set, the compression spring can buffer the pressing stroke of the pressing piece, preventing the pressing piece from moving down directly with the stopper, and protecting the sample.

Optionally, a slipper is provided between the cylindrical gear and the screw rod, the slipper includes an inner ring and an outer ring, the inner ring is coaxially sleeved in the outer ring, a gap is formed between the inner ring and the outer ring, and a The claw, one end of the claw is fixed on the inner side of the outer ring, the other end of the claw is a bent end bent at an obtuse angle, and a claw groove is provided on the outer side of the inner ring, and the bent end of the claw is inserted into the claw groove. The bent end is slidably connected with the pawl groove.

When the tablet compresses the sample, there may be overpressure and damage the sample. After setting the slipper, the outer ring is fixed coaxially with the gear, and the inner ring is fixed coaxially with the screw. When the pressure is too high, the resistance of the screw rotation increases. , the bent end of the claw comes out of the groove of the claw, the screw continues to rotate, but the claw slips on the inner ring, and the screw does not rotate, thus avoiding overpressure. When the trigger rod retreats, the bent end can slide into the claw groove again, driving the screw to reverse, thereby releasing the pressing piece.

Optionally, the pressing piece is in the shape of an inverted disc, and the pressing piece is made of spring steel.
