Description
Technical field
The present invention relates to Automobile Parts Inspection field, especially relate to a kind of test unit for detection of auto parts cold-and-heat resistent impact capacity.
Background technology
When automobile travels in the winter time; frozen water on road surface can splash in the system or assembly of heating often; owing to thering is the part of different temperatures expansion coefficient for the ability difference of cold-and-heat resistent stack; therefore frozen water be added to heating part on easily cause some material breaks or seal failure; not only bring breakage to automobile, also brought potential safety hazard for using.Therefore, the cold and hot stack that simulating vehicle is spattered the part product in region is tested, and then the cold-and-heat resistent impact capacity of check part product is extremely necessary.
Summary of the invention
Object of the present invention is exactly to provide a kind of cold shock testing device impacting for detection of auto parts cold-and-heat resistent in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions: a kind of cold shock testing device, it is characterized in that, comprise high-temperature cabinet, cryogenic box, tank, solenoid valve, the time relay, injector head, water pipe and air compressor, temperature in described high-temperature cabinet is not less than 80 ℃, temperature in described cryogenic box is 0 ℃～+ 4 ℃, described tank is filled with frozen water and is placed in cryogenic box, described injector head is communicated with tank by water pipe, described solenoid valve is located at the emitted dose of controlling injector head on water pipe, the described time relay is connected the injecting time of controlling frozen water with solenoid valve, described air compressor is connected with injector head,
Test exemplar is placed in high-temperature cabinet and is kept a period of time, after exemplar temperature stabilization to be tested, take out, utilize the position of being spattered of injector head alignment test exemplar to spray frozen water, test exemplar is placed in high-temperature cabinet afterwards again, so cycle alternation carries out high temperature and frozen water stack test.
Described injector head is flat structure, the xsect flare of injector head, wherein injector head slot is provided with water inlet, and wide mouthful is injection orifice, when test, by the position of being spattered of injection orifice alignment test exemplar, the width that injection orifice dabbles is not less than the width of testing exemplar.
Accept to spatter water test exemplar be of a size of width that single injection orifice dabbles more than 2 times time, alignment test exemplar after multiple injector heads are in a row arranged, makes the width that multiple injection orifices dabble and is not less than the width of testing exemplar.
Compared with prior art, the present invention can complete temperature and frozen water stack test, thereby and can be according to regulating injector head quantity and width of jet to meet most of test demand of testing exemplar, there is simple in structure, simple operation and the high requirement of dirigibility.
