Description

Technical Field

[0001] The present invention relates to the technology of automobile repair teaching, and more particularly to a differential and motor disassembly and assembly training device for new energy vehicle teaching. Background Art

[0002] The differential is connected to the motor by a half-conical housing. The housing has a circumferential flange with several connecting small holes. Inside the opening of the housing, components such as planetary gears, planetary gear carriers, and axle gears are arranged. After the differential travels a certain distance, it needs maintenance. During the repair, it is necessary to hold the differential and the motor on a workbench respectively, which is not only convenient for repair operations, but also hoped to be able to flip in all directions and adjust to a suitable angle according to the repair needs.

[0003] Chinese Patent with application number 202011581178.1 discloses a disassembly and assembly training workbench for the differential and motor of a new energy vehicle. A disassembly and assembly training workbench for the differential and motor of a new energy vehicle includes a teaching table, a first lead screw guide rail, a first height adjustment mechanism, a first rotary adjuster, a new energy motor body, and a differential body. The first lead screw guide rail includes a sliding plate and a transmission lead screw. A number of speed reduction regulators are installed in the speed reduction box. The first height adjustment mechanism includes a support cylinder and a load-bearing box. The first rotary adjuster includes a rotary adjustment box, a support column, a worm gear, a worm, and a transmission rod. A measuring cylinder is sleeved on the upper side of the support column. A measuring tape is fixedly connected to the upper side surface of the rotary adjustment box. The speed reduction regulator includes a speed reduction adjustment box and a second connecting gear. The new energy motor body can be adjusted with five degrees of freedom in space, so that the new energy body is more accurately docked with the differential body. Through the speed reduction adjustment of the speed reduction regulator, the adjustment process is more accurate. However, there are still some deficiencies in the implementation of this patent. During the disassembly and assembly training process for the differentials and motors of different vehicles in the training teaching process, due to the different shapes and sizes of the motors and differentials of each vehicle, different clamping plates are required to clamp and fix the motors and differentials. This patent cannot replace the fixtures portably according to the differentials and motors of different vehicles, resulting in poor applicability of the training device. At the same time, during the training demonstration process, it can only drive the motor and the differential to move up and down, left and right, and back and forth, and cannot drive the motor and the differential to flip and rotate. As a result, during the demonstration process, the motor and the differential cannot be fully demonstrated, affecting the training teaching effect. Summary of the Invention

When it is necessary to replace the clamping plate, reverse-rotate the threaded rod 32, thereby realizing the portable replacement of the clamping plate, facilitating the training device to clamp different types of motors and differentials, and further improving the applicability of the training device.

[0044] Working principle: When in use, the motor and the differential are respectively clamped and fixed on the flipping clamping mechanisms on the first mounting plate 1 and the second mounting plate 2. Subsequently, the moving mechanism 10 drives the first mounting plate 1 and the second mounting plate 2 to move, so that the motor and the differential are docked, and then the installation is carried out. At the same time, during the teaching process, the flipping clamping mechanism can drive the clamped motor and differential to flip, which is convenient for the docking and fixing between the motor and the differential. At the same time, the driving mechanism drives the support shaft 9 to rotate, and the support shaft 9 drives the first mounting plate 1 and the second mounting plate 2 to rotate, thereby driving the flipped motor and differential to rotate horizontally, so as to make the motor and the differential be displayed comprehensively and without dead angles, enabling trainees to better observe each part of the motor and the differential.
