Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle stator and rotor separation tooling technology, and in particular to a new energy vehicle transmission stator and rotor separation device. Background Technology

[0002] In order to prevent mass scrapping of transmissions during the production process of new energy vehicles, or to allow R&D engineers to have a better understanding of the internal structure of the transmission, individual products need to be disassembled and inspected. Currently, the separation of the stator and rotor involves operators using an overhead crane to hoist the gearbox onto a workbench, then using tools such as pry bars, hammers, and screwdrivers to separate the stator and rotor. After separation, the operator uses the overhead crane to peel the rotor out. During the separation process, because the stator and rotor are attracted to each other by magnets, the operator's lack of control and their skill in using the overhead crane significantly affect the separation effect. Currently, the stator is placed on a fixed platform, and the overhead crane is manually used to lift a boom lift, which is then used to connect and fix the rotor. A hollow jack is then used to press the rotor out, and the overhead crane lifts the rotor, removing it from the stator to complete the separation. However, using an overhead crane requires highly skilled operators, necessitating training to perform the operation. Therefore, to change the traditional manual disassembly method, avoid safety accidents, ensure product quality, simplify the process, and greatly reduce labor intensity, this utility model improves the existing equipment to address these problems.

A first threaded rod 10 is fixedly connected to the middle of the top surface of the driven helical gear 9. A threaded seat 11 is sleeved on the outer side of the first threaded rod 10.

[0022] Working principle: First, power is supplied to all electrical equipment. Then, the target gearbox is lifted and moved onto the mounting plate 3 using hoisting equipment. During the movement, the rotor shaft and push rod 19 are roughly positioned. Then, the push rod 19 is manually inserted into the bottom of the gearbox, with the top surface of the push rod 19 abutting against the bottom surface of the rotor. The gearbox is then aligned, and the push column 4 is installed at a suitable position on the bottom surface of the gearbox to horizontally support the gearbox. Then, the pressure frame 5 is installed at a suitable position around the gearbox to press the gearbox and fix it. Then, the mounting plate 14 is adjusted to slide left and right on the first guide plate 12, while the pressure rod 23 and the rotor move together. The shaft is then rotated, and the second threaded rod 22 is rotated by turning the handwheel 21, which causes the second threaded rod 22 to move downward, driving the bottom surface of the pressure rod 23 to abut against the top surface of the rotor, thereby cooperating with the push rod 19 to clamp the rotor from top to bottom. Then, the rotating wheel 7 is rotated, and the driving helical gear 8 is rotated through the rotating shaft, which in turn drives the driven helical gear 9 to rotate, causing the first threaded rod 10 to rotate, thereby driving the threaded seat 11 to move upward, driving the connecting plate 16 to move upward, thereby simultaneously driving the push rod 19 to push the rotor upward. During the pushing process, the auxiliary cylinder 24 provides most of the pushing force, reducing the fatigue of the workers.
