Automobile air conditioner double impeller blower assembly impeller semi-automatic press-fit tooling

Abstract

The invention relates to a semi-automatic press-fit tooling for the assembly impeller of a double impeller blower of an automobile air conditioner. The press-fit tooling includes a tooling base plate, a rotation limit mechanism, a main guide shaft, a motor shaft support mechanism, a lower impeller support error prevention mechanism for installing the lower impeller, and a locking mechanism for locking the motor. The motor cylinder body is forced to locate the locking mechanism and the upper impeller support error prevention mechanism for installing the upper impeller. The impeller motor is clamped by the motor cylinder on both sides forcibly positioning and locking the wedge block and the motor cylinder forcibly positioning and locking the main mounting plate, which ensures the repeated consistency of the positioning of the motor on the motor placement plate every time; Through the specially designed motor shaft support mechanism, the support shaft can achieve precise axial displacement only by the push of a small cylinder. At the same time, the support shaft can withstand a down force of more than 4000N. The structure is ingenious, simple and practical.

Description

technical field [0001] The invention relates to a tooling for auto parts, in particular to a semi-automatic press-fitting tooling for impellers of a double impeller blower assembly of an automobile air conditioner. Background technique [0002] The double impeller blower assembly is composed of upper impeller 0.1, impeller motor 0.2, and lower impeller 0.3 (such as figure 1 As shown), the impeller press-fitting method of the existing double impeller blower assembly uses a special base to position the impeller motor 0.2. Use a special base to position the upper impeller 0.1 and the lower impeller 0.3. For a double-impeller blower, the length of the impeller motor 0.2 shaft is longer than that of a single-impeller blower motor. The blower is positioned through a special base, and the positioning of the upper and lower shaft ends is easy to occur Large deviation, in the actual press-fitting process, the coaxiality between the 0.1 shaft hole of the upper impeller and the motor ...

AI Technical Summary

Problems solved by technology

Use a special base to position the upper impeller 0.1 and the lower impeller 0.3. For a double-impeller blower, the length of the impeller motor 0.2 shaft is longer than that of a single-impeller blower motor. The blower is positioned through a special base, and the positioning of the upper and lower shaft ends is easy to occur Large deviation, in the actual press-fitting process, the coaxiality between the 0.1 shaft hole of the upper impeller and the motor shaft is not enough, and the upper impeller will often be deformed and cracked at 0.1 pressure, resulting in scrapping

[0003] When the existing double-impeller blower assembly is press-fitted with the impeller, the lifting shaft at the lower end of the impeller motor 0.2 is used to support the motor shaft, which is manually lifted, and the production automation level is low

The limit of the existing motor placement plate is manually limited by the limit pin, and manual operation is required to release the limit, and the level of automated production is low
