Description

Technical Field

[0001] This utility model relates to new energy vehicle parts, and more particularly to a forming fixture for cooling pipes used in new energy vehicles. Background Technology

[0002] For new energy vehicles, the drive motor is the core of their drive system, and the demand for high-performance motors and high power density ratios is becoming increasingly strong. As the speed and power of drive motors in new energy vehicles increase, the need for cooling also rises. Currently, the cooling of electric drive systems is mainly achieved through cooling oil pipes; therefore, the airtightness of these cooling oil pipes has become one of the important testing items for the efficient operation of drive motors.

[0003] The cooling oil pipes for the drive motor mainly consist of a central longitudinal pipe, multiple transverse pipes, and a longitudinal tail pipe, such as... Figure 6 As shown, after processing, it is assembled into the drive motor. Since the space inside the drive motor is limited, the specifications and dimensions of the cooling oil pipes must be measured before leaving the factory to ensure they are within the specified range. Due to the crisscrossing structure, the measurement of each pipe section needs to be done manually, which is not only inefficient but also prone to measurement errors. Utility Model Content

[0004] To address the above problems, this utility model provides a compact cooling pipe forming fixture for new energy vehicles that improves the measurement efficiency of cooling oil pipes and reduces measurement errors.

[0005] The technical solution of this utility model is:
