Problems solved by technology

[0003] The existing leak detection method of the motor is to block the openings at both ends of the motor, and then pass air through one end phase to realize effective leak detection. However, in the process of leak detection of the motor casing, different motor casings are constantly changing. During the process of picking up leaks, a part of the detection liquid will be brought out. After multiple detections, the amount of detection liquid will decrease and the liquid level will drop, making it difficult for the detection liquid to effectively cover the entire motor casing, resulting in a decrease in detection accuracy.

Embodiment 1

[0036] like Figure 1-12 As shown, a device for detecting the casing of a water-cooled motor includes a detection box 1, a first blocking member 2, a second blocking member 3, an air guide pipe 4 and an opening and closing structure 5, wherein the detection box 1 is a A metal box, the detection box 1 is filled with a detection liquid, and the detection liquid can be water; the air guide pipe 4 includes a main pipe 41 and a plurality of branch pipes 42, the main pipe 41 is a metal pipe, and the main pipe 41 is buried in the At the bottom of the detection box 1, the branch pipe 42 is also a metal pipe, the branch pipe 42 is connected with the main pipe 41, the branch pipe 42 is perpendicular to the main pipe 41, and the branch pipe 42 is in line with the bottom of the detection box 1. Vertical; after the gas is passed into the main pipe 41, it will then be sent out through each branch pipe 42.

[0037] Further, the first blocking part 2 is connected to the lower part of the mot...

Embodiment 2

[0045] like Figure 11-13 As shown in the figure, the difference between this embodiment and the first embodiment is that this embodiment is additionally provided with a liquid supply part 6 for providing detection liquid in the phase detection box 1 to cover the motor casing. Specifically: the liquid supply part 6 It includes a liquid supply pipeline 61, a pump body 62, a switch part 63 and a floating part 64, the liquid supply pipeline 61 is a metal pipeline, and the liquid supply pipeline 61 is communicated with the bottom of the detection box 1, so that the liquid supply pipeline The detection liquid in 61 will be discharged from the bottom of the detection box 1, which ensures that the liquid in the detection box 1 will not have bubbles during the discharge process, and the stability of detection is ensured; the pump body 62 is a water pump, The pump body 62 is communicated with the liquid supply pipeline 61, the switch member 63 is a conventional switch on the market, wh...

Abstract

The invention discloses a device used for detecting a shell of a water-cooled motor, comprising a detection box used for containing a detection liquid, an open and close structure arranged on the branch pipe and used for opening the branch pipe when the branch pipe penetrates into the first plugging part, so as to introduce a gas into the shell of the motor, and a liquid supply part used for supplying water into the detection box until a water level is above the shell of the motor. The device disclosed by the invention is provided with the liquid supply part used for feeding the detection liquid into the detection box, in the process, the water level of the detection liquid is a constant value, and then the detection liquid can be completely above the top of the shell of the motor when theshell of the motor is detected in the detection liquid, thus detection accuracy is improved, and detection effect is guaranteed; meanwhile, the liquid supply part belongs to automatic liquid supply,manual operation is reduced, labor cost is saved, and working strength of a worker is reduced.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a device for detecting a casing of a water-cooled motor. Background technique [0002] Water-cooled motors have generally existed in the market. By setting a cavity on the motor casing, and then through water circulation, the heat generated inside the motor is heat-exchanged. The overall stability during the working process improves the service life of the motor; because the motor is energized inside, the water-cooled motor cannot leak water during the production process. Therefore, in the process of producing the motor, it is necessary to check the outer casing of the motor to ensure the use of the motor. security. [0003] The leakage detection method of the existing motor is to block the openings at both ends of the motor, and then pass air through one end of the phase to achieve effective leakage detection. During the leak detection process, a part o...
