Hole position detection tool for automobile air conditioning evaporator left casing

Abstract

The invention discloses a hole position detection tool for an automobile air conditioning evaporator left casing. The detection tool comprises a base plate (1), a first mounting plate (2), two second mounting plates (3) and at least two rapid clamping mechanisms (4). Three throttle hole position elastic detection columns (A) are mounted on the first mounting plate (2), two automobile body mounting hole position elastic detection columns (B) are mounted on the upper second mounting plate (3), and an automobile body mounting hole position elastic detection column (B) is mounted on the lower second mounting plate (3). The throttle hole position elastic detection columns (A) and the automobile body mounting hole position elastic detection columns (B) are composed of cylindrical rods (5) and return springs (6). The detection tool is simple in structure and ingenious in design, whether machining of the throttle hole positions and the automobile body mounting holes in the left casing are eligible can be detected through the detection tool, the detection tool is quick and convenient, waste of assembly time caused by the incapability of assembling is effectively prevented, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle air-conditioning processing and inspection tools, and in particular relates to a hole position inspection tool for the left casing of an automobile air-conditioning evaporator. Background technique [0002] The evaporator assembly (abbreviated as NBM1) is a crucial component in the automotive air-conditioning system, which has a significant impact on the cooling effect of the air conditioner. It uses liquid low-temperature refrigerant to evaporate easily at low pressure, convert it into vapor and absorb the cooled medium heat, so as to achieve the purpose of cooling. [0003] The left shell of the vehicle air conditioner evaporator is an essential part of the evaporator assembly. It is an injection-molded shell structure. After the left shell is formed, it must be installed with the damper and the body. There is a damper on the left shell. holes and body mounting holes. After the left casing is ...

AI Technical Summary

Problems solved by technology

After the left casing is processed, if the hole position error value exceeds the allowable range, it cannot be installed with the damper and the body.

At present, the hole position inspection tool of the left shell has not been designed. It is necessary to wait until the part is assembled to find out whether the product hole position is qualified, which brings a lot of trouble to the assembly.
