Problems solved by technology

[0005] Aiming at problems such as large detection errors of the conventional detection tools used in the prior art, the present invention designs a vehicle air-conditioning HVAC assembly installation detection tool and its detection method. The left rear positioning seat is symmetrically installed on one side of the upper surface of the bottom plate. and the right rear positioning seat, the other side of the upper surface of the bottom plate is symmetrically installed with a steam core inspection tool and a warm core inspection tool, the HVAC shell is placed on the left rear positioning seat and the right rear positioning seat, and the HVAC The installation grooves provided on both sides of the housing are engaged with the positioning mechanisms respectively provided on the left rear positioning seat and the right rear positioning seat, so that the steam core and the warm core on the HVAC housing are respectively in contact with the steam core. The tool corresponds to the warm core inspection tool, which can effectively solve the problems of poor sealing of each pipeline connection during installation caused by the overall distortion and deformation of the HVAC assembly, thereby improving the accuracy of installation inspection

Abstract

The invention discloses an automobile air conditioner HVAC assembly installation detection tool and a detection method thereof, and belongs to the technical field of automobile air conditioner assembly inspection. The automobile air conditioner HVAC assembly installation detection tool comprises a bottom plate, a left rear positioning seat and a right rear positioning seat are installed on one side of the upper surface of the bottom plate in a bilateral symmetry mode, and a steam chip detection tool and a worm chip detection tool are installed on the other side of the upper surface of the bottom plate in a bilateral symmetry mode. During detection, mounting grooves formed in the two sides of a HVAC shell are clamped on the positioning mechanisms arranged on the left rear positioning seat and the right rear positioning seat respectively, so that accurate positioning of the HVAC shell is realized, and the HVAC shell is prevented from deflecting to influence detection precision in the detection process; and a telescopic mechanism I and a telescopic mechanism II drive a steam chip detection tool die head and a warm chip detection tool die head to slide back and forth, so that the matching hole sites on a steam chip and a warm chip on the HVAC shell are detected at the same time to judge whether the dimensional tolerance meets the actual loading requirement or not.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioner assembly inspection, and more specifically relates to an automobile air conditioner HVAC assembly installation inspection tool and a inspection method thereof. Background technique [0002] Automotive air conditioning systems generally include heaters, refrigerators, fans, condensers, compressors, operating mechanisms, connecting pipelines (refrigerant, coolant, air) and control wiring harnesses. Its heater, refrigerator, and fan constitute the HVAC assembly of the air conditioning system, which is a body part of the automobile air conditioning system. The defrosting and defogging of glass provides comfortable driving conditions for car drivers and passengers. The blowing surface of the duct and instrument panel and the defrosting of the side windows, the foot blowing ducts are respectively connected to the corresponding air outlets of the air conditioner HVAC, so it is particu...
