Description

Technical Field

[0001] This utility model belongs to the field of motor core manufacturing and testing technology, specifically relating to a complex oil circuit testing device for new energy vehicle cores. Background Technology

[0002] With the development of new energy vehicle motors, the power-to-weight ratio is getting higher and higher. The original air-cooling and water-cooling modes can no longer meet the heat dissipation requirements of higher power density. The new cooling method adopts a method of digging specific grooves in the iron core body and using cooling oil for direct cooling.

[0003] Because the iron core is made up of stamped laminations, there is a probability of debris getting trapped between the laminations. Conventional inspections cannot guarantee the continuity of the oil holes through visual inspection. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a device for detecting complex oil circuits in the iron core of new energy vehicles.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a complex oil circuit detection device for iron core of new energy vehicle, including a shell, the shell being a hollow cylindrical structure, a bottom limiting platform provided at the bottom of the shell, two sets of limiting rings provided on the inner wall surface of the shell, a through hole provided on the shell within each limiting ring, a threaded hole provided on the shell between the two sets of limiting rings, an annular airbag provided in each of the two sets of limiting rings, an air pipe connector connected to the threaded hole of the shell on each of the two annular airbags, and the air pipe connectors on the two annular airbags being placed in the through hole of the shell; The housing is provided with a pin mounting seat, and a rotating shaft is provided in the pin mounting seat. The rotating shaft is rotatably connected to the pin mounting seat, and a set of wind measuring components are symmetrically provided at the upper and lower ends of the rotating shaft. The wind measurement component includes a mounting plate, which is circular in shape and has a socket at one end. The mounting plate is connected to a rotating shaft through the socket. The mounting plate is provided with an annular pressure plate, and several fiber threads are pressed between the mounting plate and the annular pressure plate.

[0006] Preferably, several fiber filaments are evenly distributed in a ring between the mounting plate and the ring pressure plate.

[0007] Preferably, the fiber filaments are made of a flexible material.

[0008] Preferably, the housing, the annular airbag, and the mounting plate are all arranged on the same axis.

[0009] The beneficial effects of this utility model are as follows: by setting two annular airbags and a wind measuring component, and setting an air pipe connector on the shell between the two, the two annular airbags completely seal the outside of the iron core, and the air pipe connector injects air into the oil hole of the iron core. By observing the direction of multiple fiber filaments in the wind measuring component, it is possible to directly visually determine whether the oil hole is open, which is convenient for staff to observe. By sealing the outer wall of the iron core with an annular airbag, the gas injected into the oil hole can be prevented from leaking out, thus ensuring that the gas flowing in the oil hole has a certain pressure, which makes it easier to blow the fiber filaments for observation.

[0013] Example: A device for detecting complex oil circuits in the core of a new energy vehicle, such as... Figures 1-2 As shown, the device includes a housing 1, which is a hollow cylindrical structure. The bottom of the housing 1 is provided with a bottom limiting platform 2. Two sets of limiting rings 3 are provided on the inner wall of the housing 1. Each of the limiting rings 3 has a through hole 4. A threaded hole 5 is provided on the housing 1 between the two sets of limiting rings 3. An annular airbag 6 is provided in each of the two sets of limiting rings 3. An air tube connector 7 is connected to each of the two annular airbags 6 and the threaded hole 5 of the housing 1. The air tube connector 7 on the two annular airbags 6 is placed in the through hole 4 of the housing 1. The housing 1 is provided with a pin mounting seat 8, and a rotating shaft 9 is provided in the pin mounting seat 8. The rotating shaft 9 is rotatably connected to the pin mounting seat 8, and a set of wind measuring components are symmetrically provided at the upper and lower ends of the rotating shaft 9. The wind measurement component includes a mounting plate 10, which is ring-shaped and has a socket 11 at one end. The mounting plate 10 is connected to the rotating shaft 9 through the socket 11. The mounting plate 10 is provided with an annular pressure plate 12, and a number of fiber threads 13 are pressed between the mounting plate 10 and the annular pressure plate 12.

[0014] Several fiber filaments 13 are evenly distributed in a ring between the mounting plate 10 and the annular pressure plate 12; the fiber filaments 13 are made of flexible material; the shell 1, the annular airbag 6 and the mounting plate 10 are all arranged on the same axis.

[0015] The principle of this invention: When using the testing device, the iron core is first placed inside the housing 1, and the bottom is supported by the bottom limiting platform 2. The iron core is made of multiple stacked laminations, and the laminations have intersecting oil holes. The oil holes of the multiple laminations are stacked to form oil channels. An oil inlet is provided in the middle of the iron core, which extends to the upper and lower sides of the iron core. The outer periphery of the annular airbag 6 is positioned by the limiting ring 3 to ensure its stability during the testing process. The air pipe connector 7 is connected to an external air source to fill the testing device with compressed air. The annular airbag 6 is set on the inner wall of the housing 1 and expands through the air pipe connector 7 to seal and fix the iron core. The mounting plate 10 is connected to the housing 1 through the pin mounting seat 8 and can rotate around the rotating shaft 9 to facilitate the insertion and removal of the iron core. During the test, compressed air is filled into the oil channel inside the iron core, and the change of the fiber filaments 13 is used to judge whether the oil channel is unobstructed, thereby completing the efficient testing of the iron core oil channel.
