Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts testing, in particular to an ice-water impact test chamber for environmental testing. Background Technique

[0002] The ice-water impact test chamber mainly simulates the thermal shock test caused by ice water for products applied in the shallow water area of vehicles. The purpose is to simulate the situation when ice water splashes onto the heating system or components when driving on a wet road in winter. It is a reliability testing device for various raw materials and devices such as electronics, electricians, electrical appliances, plastics, etc. to conduct cold resistance, heat resistance, ice-water splash resistance test, ice-water immersion resistance test and quality control engineering. When conducting the ice-water impact experiment, the object needs to be placed on the placement table, and then the object is subjected to the ice-water impact experiment through the spraying mechanism. Since the spraying mechanism is fixed at the top of the low-temperature area, the ice water mainly conducts the impact experiment on one place of the object at a fixed angle. As is well known, the external environment is in a constantly changing state and will impact the object at different angles, resulting in inaccurate experimental data of the object. And after the ice-water impact test, the object also needs to be subjected to the environmental shock experiment of alternating hot and cold environments. Then, the object needs to be placed in a high-temperature environment, and the time for changing the hot and cold environments is relatively long, which may affect the test data. For this reason, we propose an ice-water impact test chamber for environmental testing. Summary of the Invention

[0003] The utility model provides an ice-water impact test chamber for environmental testing, which solves the problems raised in the above background technique.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: An ice-water impact test chamber for environmental testing includes an experimental chamber body. An ice-water storage chamber, a low-temperature area, and a high-temperature area are respectively arranged in the experimental chamber body from top to bottom. And a spraying mechanism is arranged inside the low-temperature area. The spraying mechanism is connected to the ice-water storage chamber through a hose. The inner wall of the bottom of the low-temperature area is fixed with a moving slide rail for limiting the movement of the spraying mechanism, and the moving slide rail is arc-shaped. And a first rotating wheel is circularly movably sleeved on the experimental chamber body. The first rotating wheel is between the low-temperature area and the high-temperature area. A second rotating wheel is circularly movably sleeved on the first rotating wheel. A ratchet structure is formed between the first rotating wheel and the experimental chamber body, and a ratchet structure is formed between the second rotating wheel and the first rotating wheel. And the two ratchet structures are arranged in the opposite direction. At the same time, a clamping column is movably connected to the inner side of the first rotating wheel, and the clamping column is in contact with the second rotating wheel.

[0005] Optionally, teeth are provided inside the moving slide rail. A second motor is fixed inside the spraying mechanism. A gear is fixed to the output shaft of the second motor, and the gear engages with the teeth inside the moving slide rail.

[0006] Optionally, a first ratchet groove is formed in the circular surface of the experimental chamber body in contact with the first rotating wheel, a first receiving groove is formed outside the first rotating wheel, a first ratchet tooth is connected in the first receiving groove through a shaft pin, and one end of the first ratchet tooth extends into the first ratchet groove.

[0007] Optionally, a first spring is fixed inside the first ratchet tooth, and one end of the first spring is fixed to the inner wall of the first receiving groove.

[0008] Optionally, a second ratchet groove is formed in the circular surface of the first rotating wheel in contact with the second rotating wheel, a second receiving groove is formed outside the second rotating wheel, and a second ratchet tooth is connected in the second receiving groove through a shaft pin.

[0009] Optionally, one end of the second ratchet tooth extends into the second ratchet groove, a second spring is fixed inside the second ratchet tooth, and one end of the second spring is fixed to the inner wall of the second receiving groove.

[0010] Optionally, a first motor is fixed outside the experimental chamber body, and the output shaft of the first motor passes through the experimental chamber body and is fixed to the center of the second rotating wheel. A linkage rod is connected between the second rotating wheels, and the linkage rod is movably sleeved on the first rotating wheel.

[0011] Optionally, one side of the second rotating wheel is a continuously corrugated arc surface and abuts against one end of the clamping column. The abutting end of the clamping column is circular. A third spring is sleeved on the clamping column. One end of the third spring is fixed to the first rotating wheel, and the other end of the third spring is fixed to the clamping column.

[0012] The utility model has the following beneficial effects:

[0013] 1. For the ice-water impact test chamber for environmental testing, driven by the output shaft of the second motor, the gear can rotate, and then drive the spraying mechanism to move, so that the spraying mechanism can perform circular movement, and then perform ice-water impact experiments on the object at different angles, so that the object can be more fully tested, and the experimental data is more accurate.

[0014] 2. For the ice-water impact test chamber for environmental testing, through the forward rotation of the first motor, the second rotating wheel can be driven to rotate alone, and then the second rotating wheel can push the clamping column to move. The clamping column extends out of the first rotating wheel to clamp the object. When the first motor rotates in the reverse direction, it can drive the second rotating wheel and the first rotating wheel to rotate together, so that the clamped object can smoothly change the environment, making the use more convenient and intelligent.

[0015] 3. The ice-water impact test chamber for environmental testing has a ratchet structure between the first rotating wheel and the experimental chamber body and a ratchet structure between the second rotating wheel and the first rotating wheel arranged in the opposite direction. Then, when the second rotating wheel rotates forward, the first ratchet tooth can lock the first rotating wheel to achieve the effect of the second rotating wheel rotating alone. When the second rotating wheel rotates backward, the first ratchet tooth can lock between the second rotating wheel and the first rotating wheel to achieve the effect of the second rotating wheel and the first rotating wheel rotating together. Furthermore, a single first motor can both drive the clamping column to clamp an object and drive the clamped object to rotate, thus ensuring its normal operation. Description of the Drawings

And driven by the output shaft of the second motor 18, the gear 17 can rotate, thereby driving the spraying mechanism 3 to move along the moving slide rail 4 to adjust the angle of the spraying mechanism 3. Then the output shaft of the first motor 7 rotates in the reverse direction. At this time, the first ratchet 10 moves into the first receiving groove, and the second ratchet 12 is inserted into the second ratchet groove. The second rotating wheel 8 will not rotate, and then the second rotating wheel 8 can drive the first rotating wheel 9 to rotate together and then rotate into the high-temperature area 6 to conduct a thermal shock experiment on the object.
