[0020] The following refers to Figures 1-7 describe the present invention; An efficient detection device for the cooling pipeline of a driving motor of a new energy vehicle includes an airtight fixture for the cooling oil pipeline of the driving motor and a forming fixture for the cooling oil pipeline.

Specifically, a plurality of limiting blocks 211 fixedly connected by connecting members are provided on the top surface of the support base 210. As Figure 4 shown, the plurality of limiting blocks 211 are respectively located at the edges close to the corresponding limiting grooves.

[0021] The support base 210 includes: A first transverse seat 212, detachably arranged on the top surface of the airtight workbench through a connecting member; A second transverse seat 213, detachably arranged on the top surface of the airtight workbench through a connecting member, located on the side of the first transverse seat 212; in this case, the second transverse seat 213 is parallel to the first transverse seat 212; A third transverse seat 214, detachably arranged on the top surface of the airtight workbench through a connecting member, located on the side of the first transverse seat 212, and having a spacing from the second transverse seat 213; in this case, the third transverse seat 214 is parallel to the first transverse seat 212; A fourth transverse seat 215, detachably arranged on the top surface of the airtight workbench through a connecting member, located on the side of the third transverse seat 214.

The top surface of the tail longitudinal seat 217 is an inclined surface, which is adapted to the cooling oil pipe 100.

[0023] A number of elastic sealing gasket 220 are provided and are respectively fixedly arranged in the limiting grooves, corresponding to the cooling spray holes of the cooling oil pipe 100; both ends of the elastic sealing gasket 220 climb to the top surface of the support seat 210 respectively; in this case, the elastic sealing gasket 220 is a rubber gasket, and the cooling spray holes of the cooling oil pipe 100 are sealed through the corresponding elastic sealing gaskets 220 respectively; The air inlet linear driving mechanism 230 is detachably and fixedly arranged at the oil inlet of the cooling oil pipe 100 through a connecting piece. An air inlet column 231 is arranged at the piston rod end of the air inlet linear driving mechanism 230, and an air inlet hole connected to the air source is arranged on the end surface of the air inlet column 231; a first sealing ring 232 is fixedly connected to the orifice of the air inlet hole; when the piston rod of the air inlet linear driving mechanism 230 extends out, the first sealing ring 232 is butted against the oil inlet of the cooling oil pipe 100; The air inlet linear driving mechanism 230 includes an air inlet cylinder, an air inlet oil cylinder or an air inlet electric push rod.

[0024] The air blocking linear driving mechanism 240 is detachably and fixedly arranged at the oil return port of the cooling oil pipe 100 through a connecting piece. A second sealing column 241 fixedly connected to the piston rod end of the air blocking linear driving mechanism 240 is made of the same material as the sealing ring and is used to block the oil return port of the cooling oil pipe 100; The air blocking linear driving mechanism 240 includes an air blocking cylinder, an air blocking oil cylinder or an air blocking electric push rod.

[0026] The pressing linear driving mechanism 251 includes a pressing cylinder, a pressing oil cylinder or a pressing electric push rod. The pressing plate 250 slides up and down above the support seat 210 through a pair of guiding columns.

[0027] After the cooling oil pipe 100 enters the limit groove, the piston rod of the pressing linear drive mechanism 251 presses down, pressing a plurality of elastic pressing blocks 252 onto the upper surface of the cooling oil pipe 100. The plurality of cooling spray holes of the cooling oil pipe 100 are closed through corresponding elastic sealing gasket 220. After the cooling oil pipe 100 is hermetically fixed, the intake linear drive mechanisms 230 and the air-blocking linear drive mechanism 240 on both sides start to work respectively; the second sealing column 241 at the piston rod end of the air-blocking linear drive mechanism 240 seals the oil return port. While the intake linear drive mechanism 230 seals the periphery of the oil inlet, the intake function of the cooling oil pipe 100 is realized through the intake hole and the middle hole of the first sealing ring 232.

After the pressing linear drive mechanism 251 continues to press down to the set position, it stops. The combined structure of multiple cross beams and multiple pressing plates forms a multi-point support system for the cooling oil pipe 100, and the elastic element spring A can evenly distribute the load. The adjustable fixed connection between the pressing plate 253 and the adjusting screw 2541 realizes the function of adjustable pressure of the spring A, dynamically adjusts the pressing force according to the actual working conditions, avoids component damage caused by excessive pressure, and at the same time, the elastic buffering effect of the spring A can effectively absorb the impact load.

By pressing down the buffer column 262, the buffer rod 261 is compressed into the buffer sleeve 260 for the first buffer, and then the elastic pressing block 252 contacts the cooling pipe again for the second buffer, effectively solving problems such as easy deformation during the detection of the cooling oil pipe 100.
