Motor airtightness detection device

Abstract

The invention discloses a motor airtightness detection device. The device comprises a body, the device is characterized in that a working cavity which is through left and right is formed in the body;three sections of conveying belt mechanisms are horizontally arranged in the working cavity; a to-be-detected motor is conveyed into the working cavity through the third section of the conveying beltmechanism from left to right; the first section of the conveying belt mechanism is conveyed away from the working cavity from left to right, a to-be-repaired cavity is formed below the working cavity,a descending opening communicating with the working cavity is formed in the upper right portion of the to-be-repaired cavity, a second air cylinder is arranged below the descending opening, and a second air cylinder rod capable of extending up and down is arranged at the upper end of the second air cylinder; according to the device, the lower pressing block moves downwards to enable the motor shell to sink slightly; the sealing ring deforms, meanwhile, the hollow screw rod is rotationally sleeved with the airtight threaded sleeve, so that an airtight environment is constructed, a vacuum environment is constructed for the sealing ring through an air pump, then the sealing ring is static for a moment, and whether the airtightness of the motor to be detected is good is determined by detecting the internal air pressure of the sealing ring.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor air tightness detection device. Background technique [0002] As an indispensable and important part of all kinds of electric machinery nowadays, the motor has a huge market demand, and under the huge market demand, the quality of the motor to be tested will naturally increase, and the airtightness of the motor is undoubtedly It is an extremely important part. Existing air tightness detection devices are often tested by gap contact with probes. This type of method not only has low efficiency, but also has a large error rate. Contents of the invention [0003] The object of the present invention is to provide a motor air tightness detection device for overcoming the above-mentioned defects in the prior art. [0004] A motor airtightness detection device according to the present invention includes a fuselage, and is characterized in that: the fuselage is provided with a l...
