Problems solved by technology

[0003] The existing motor leak detection method is to block the openings at both ends of the motor, and then let air into the interior through one end, so as to realize effective leak detection. However, in the process of leak detection of the motor casing, different motor casings In the process of continuous leak detection, 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 completely cover the entire motor casing, resulting in accurate detection. sex decline

Embodiment 1

[0036] Such as Figure 1-12 As shown, a device for detecting the shell of a water-cooled motor includes a detection box 1, a first blocking part 2, a second blocking part 3, an air guide pipe 4 and an opening and closing structure 5, wherein the detection box 1 is Metal box, detection liquid is loaded into in this detection box 1, and described detection liquid is that can be water; Described air guide pipe 4 comprises main pipe 41 and a plurality of branch pipes 42, and described main pipe 41 is metal pipeline, and this main pipe 41 is embedded in At the bottom of the detection box 1, the branch pipe 42 is also a metal pipe. Vertically; after the gas passes into the main pipe 41 , it will pass through each branch pipe 42 to the outside.

[0037] Further, the first blocking part 2 is connected to the lower part of the motor casing, thereby blocking all openings in the lower part of the motor casing, and the second blocking part 3 is used to block the openings in the upper par...

Embodiment 2

[0045] Such as Figure 11-13 As shown, the difference between this embodiment and Embodiment 1 is that this embodiment is additionally equipped 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 member 63 and a floating member 64. The liquid supply pipeline 61 is a metal pipeline, and the liquid supply pipeline 61 communicates 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, and the liquid in the detection box 1 will not have air bubbles in the process of discharging, so as to ensure the stability of detection; the pump body 62 is a water pump, The pump body 62 communicates with the liquid supply pipeline 61, and the switch member 63 is a conventional switch on the market, which can be opened and clos...

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 water-cooled motor casing. Background technique [0002] Water-cooled motors have been widely available 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 cooling effect is good, and it can effectively protect the motor. The overall stability during the working process improves the service life of the motor; because the motor is powered internally, the water-cooled motor cannot leak water during the production process. Therefore, in the process of producing the motor, it is necessary to perform leak detection on the motor shell to ensure the use of the motor security. [0003] The existing motor leak detection method is to block the openings at both ends of the motor, and then let air into the interior through one end, so as to real...
