Fast airtightness detection device of motor machine shell cavity body of new-energy automobile

Abstract

The invention belongs to the technical field of airtightness detection equipment, and particularly relates to a fast airtightness detection device of a motor machine shell cavity body of a new-energyautomobile. The device includes a base seat. A support frame is fixedly mounted on the top of the base seat. A glass water tank is arranged at the top of the base seat. A first pushing rod motor is arranged on the support frame. A fixing block is fixedly mounted at a bottom end of an output rod of the first pushing rod motor. A hanging basket is arranged below the fixing block. A machine shell isarranged on the hanging basket, and is located in the glass water tank. A second pushing rod motor is arranged on the hanging basket. A pressure plate is fixedly mounted at a bottom end of an output shaft of the second pushing rod motor. The bottom of the pressure plate is in contact with the top of the machine shell. According to the device, a structure is simple, operations are convenient, the hanging basket can be rotated through power provided by a servo motor to rotate the machine shell in water, walking observation of detection personnel around equipment is avoided, thus fast and comprehensive observation and detection of people on airtightness of the machine shell are facilitated, detection speed is improved, and great convenience is brought to the people.

Description

Technical field [0001] The invention relates to the technical field of air tightness detection equipment, in particular to a rapid air tightness detection device for a housing cavity of a new energy automobile motor. Background technique [0002] With the continuous development of the economy and the increasing air pollution, people are paying more and more attention to new energy vehicles. Various new energy vehicles have been developed, especially pure electric vehicles. Motors are the core components of pure electric vehicles. The enclosures of ”have high requirements for airtightness, and airtightness testing is required during the production process of the enclosure. The airtightness testing equipment currently in use is basically tested by means of enclosed water immersion. [0003] However, the existing airtight detection equipment design still has shortcomings. Its closed immersion mechanism cannot be rotated, and the inspector needs to observe the equipment in a circle, wh...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a fast airtight detection device for the motor housing cavity of a new energy vehicle, so as to solve the problem that the closed water immersion mechanism of the original airtight detection equipment proposed in the above-mentioned background technology cannot rotate, and the detection personnel need to surround The equipment observes a circle, which makes it inconvenient to quickly and comprehensively observe and detect the water-soaked casing, and the detection speed is slow, which affects people's use
