[0002] New energy vehicles are one of the main development directions of modern vehicles. They are composed of multiple components. For example, the motor is a relatively core component among them. During the production process, generally, after each component is produced and assembled, the final assembly task is carried out. During this process, since the motor component itself is relatively heavy, a positioning device for the automobile motor is required during installation;

[0003] When the existing positioning devices for automobile motors are in use, many of them are designed for and assist in installing limited models of automobiles and corresponding models of motors. This makes it often inconvenient to position the corresponding motors of different models to the corresponding positions for installation, greatly reducing their applicability. Summary of the Utility Model

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0027] Please refer to Figures 1-4 As shown, the present utility model is a rotary positioning device for an automotive motor, including a four-corner bracket 1, and a controller is provided on a supporting part of the four-corner bracket 1;

[0028] As Figure 1 shown, a self-driving plate 2 is provided on the inner side wall of the four-corner bracket 1, and a self-driving box 3 is provided at the bottom of the rotating shaft 6. The bottom inside the self-driving box 3 is penetrated by a first hydraulic cylinder assembly 4, and the output end of the first hydraulic cylinder assembly 4 is connected to a mounting part 5. Both the self-driving plate 2 and the self-driving box 3 are horizontally moved by devices such as electric push rods or hydraulic cylinders. The central axis of the first hydraulic cylinder assembly 4 is perpendicular to the horizontal central axis of the self-driving box 3, and the first hydraulic cylinder assembly 4 is rotationally connected to the self-driving box 3. The first hydraulic cylinder assembly 4 is connected to the self-driving box 3 through a thrust bearing, so as to ensure that it can withstand the downward pulling force;

[0029] As Figure 4 shown, a rotating shaft 6 is provided on the inner side wall of the mounting part 5. A worm gear 7 is installed on the outer side of the rotating shaft 6 near one end, and a clamping part 8 is installed on the outer side of the rotating shaft 6 far from the worm gear 7. Both ends of the inner side wall of the clamping part 8 are installed with a second hydraulic cylinder assembly 9. The rotating shaft 6 and the clamping part 8 are integrally made, and the rotating shaft 6 is rotationally connected to the mounting part 5 to ensure the connection strength during use;

[0030] As Figure 1As shown in the figure, a driving mechanism for driving the first hydraulic cylinder assembly 4 to rotate is provided on the self-driving box 3. The driving mechanism includes a first servo motor main body 13. The first servo motor main body 13 is installed at the top inside the self-driving box 3. The output end of the first servo motor main body 13 is connected with an output shaft 14, and the bottom end of the output shaft 14 is fixedly connected with the first hydraulic cylinder assembly 4;

[0031] As Figure 4 shown in the figure, an actuating mechanism for driving the rotating shaft 6 to rotate is provided on the mounting member 5. The actuating mechanism includes a second servo motor main body 15. The second servo motor main body 15 is installed on one side of the mounting member 5. The output end of the second servo motor main body 15 is connected with a worm 16. The central axis of the worm 16 is perpendicular to the central axis of the worm gear 7, and the worm 16 is meshed with the worm gear 7. When the worm 16 rotates, the rotating shaft 6 can complete the corresponding rotation task. At the same time, since the worm gear 7 cannot drive the worm 16 to rotate, the torsional force that adjusts the clamping member 8 to an inclined state will not be transmitted to the worm 16 and the second servo motor main body 15, thereby reducing the load on the second servo motor main body 15; Embodiment 2

[0032] As Figure 4 shown in the figure, a spring 11 is installed at the middle position of the bottom of the clamping member 8, and a rubber plate 12 is installed at the bottom end of the spring 11. When picking up the motor, when the motor is too large, the rubber plate 12 will collide with the top of the motor instead of the clamping member 8, and the rubber plate 12 and the spring 11 will undergo corresponding elastic deformations to avoid damaging the motor;

[0033] The output end of the second hydraulic cylinder assembly 9 is connected with a fitting 10, and the side cross-sectional shape of the fitting 10 is "U" shaped. When the two fittings 10 move towards the middle, they can clamp the cylindrical motor. At the same time, the four points are in contact with the motor, and the clamping is stable. At the same time, motors with different diameters can be clamped.

[0034] Working principle of the utility model: The vehicle body or the speed reducer is located directly below the four-corner bracket 1, which facilitates the subsequent installation of the motor thereon. The motor is moved to one side below the four-corner bracket 1 by the trolley. The movement of the self-driving plate 2 and the self-driving box 3 is controlled so that the clamping member 8 is directly above the motor on the trolley. The first servo motor main body 13 is controlled to drive the corresponding rotation of the first hydraulic cylinder assembly 4 through the output shaft 14 until the two second hydraulic cylinder assemblies 9 are respectively located on one side of the motor on the trolley. The first hydraulic cylinder assembly 4 is controlled to drive the clamping member 8 to move downward until it reaches the position where the fitting 10 can clamp the motor. At the same time, during this process, when the motor touches the rubber plate 12, the rubber plate 12 and the spring 11 can be correspondingly compressed and will not have a hard collision with the motor. Subsequently, the second hydraulic cylinder assembly 9 is controlled to drive the fitting 10 to move towards the middle direction so that the outer side wall of the motor can clamp it. Since the cross-sectional shape of the fitting 10 is "U" shaped, four-point clamping of the side wall of the motor can be implemented, thereby ensuring the stability of clamping and simultaneously completing the clamping task for motors with different diameters;

[0035] After the above-mentioned motor clamping task is completed, the first hydraulic cylinder assembly 4 is controlled to drive the motor to leave the trolley and rise to the designated position. At this time, the angle of the motor can be further adjusted on the horizontal plane by controlling the first servo motor main body 13. At the same time, the second servo motor main body 15 can be controlled to drive the corresponding rotation of the worm 16. Through the meshing connection between the worm 16 and the worm wheel 7, the angle of the motor can be driven to be adjusted on the vertical plane. At the same time, the motor can be further driven to move correspondingly by the self-driving plate 2 and the self-driving box 3. Thus, the motor can be installed at the designated position at a designated angle, greatly increasing the applicability of the device.

[0036] The above has described a detailed description of an embodiment of the utility model, but the content described is only the preferred embodiment of the utility model and cannot be considered as used to limit the scope of implementation of the utility model. All equal changes and improvements made according to the scope of the application of the utility model should still fall within the scope covered by the patent of the utility model.
