Accelerated-heat-aging test device used for inspection of automobile parts

Abstract

The invention provides an accelerated-heat-aging test device used for inspection of automobile parts. The device comprises wind guiding plates, a screw cap, support hanging rods, a positioning suspending rod, a sliding top cover, positioning insertion rods, an upper positioning ring and a lower positioning ring. An insertion ring is supported and disposed at the center of a top end of the screw cap. The five support hanging rods are also supported and disposed on an end face of a periphery of the insertion ring in a manner of an annular array. Each of top ends of the five support hanging rodssupports a seizing piece with a positioning hole inwards. A sliding top cover is disposed on the positioning suspending rod in a sleeving manner. The sliding top cover is located above the upper positioning ring. The five positioning insertion rods are supported and disposed on a bottom ring plate of the sliding top cover in a manner of an annular array. According to disposing of a packing-auger wind guiding vane of the invention, the packing-auger wind guiding vane has a spiral guiding function, and spiral eddy currents are more easily formed inside a cyclone cylinder 10 under auxiliary guiding thereof.

Description

technical field [0001] The invention belongs to the technical field of thermal aging experiments of auto parts, and more specifically relates to an accelerated thermal aging test device for testing auto parts. Background technique [0002] Aging test mainly refers to thermal oxygen aging test for rubber, plastic products, electrical insulation materials and other materials; or ventilation aging test for auto parts and plasticized products. [0003] After retrieval, for example, the patent No. CN205301213U discloses a thermal aging test chamber, which includes a main casing, a laboratory is arranged in the main casing, a rotating table for placing test samples is provided at the bottom of the laboratory, and the inner wall of the laboratory is There are multiple ultraviolet lamps and xenon arc lamps on the top, and a control panel is provided on the outer wall of the main box. The control panel is used to control whether the rotary table rotates, turn on or off the ultraviole...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides an accelerated thermal aging test device for auto parts inspection, to solve the problem that the existing thermal aging test device for auto parts cannot be applied to the uniform heating of the antifreeze water tank with an irregular shape. The heating efficiency of the gas is low and uneven, resulting in the problem of local temperature differences inside the device
