Abstract
Description
Technical Field
[0001] The utility model is applied to the technical field of copper bar clamping and positioning, and particularly relates to a three-phase copper bar clamping mechanism. Background Art
[0002] A motor controller is an integrated circuit that actively controls the motor's direction, speed, angle, and response time. It converts the stored energy in the power battery into the energy needed to drive the motor, controlling the vehicle's starting, forward and backward speed, and hill climbing performance. It also assists with braking, storing some of the braking energy in the power battery. During the motor controller production process, the assembled product undergoes a power-on test. The motor controller is connected to an external power source via a three-phase copper busbar. During this connection process, the busbar's three sets of connectors must be connected to the external power source's connectors. Currently, this is typically done manually, sequentially connecting the three busbar connectors to the three high-voltage wiring harnesses. This method is labor-intensive, unsafe, and requires three separate connections. This significantly increases direct contact with the high-voltage wiring harness during manual connection, resulting in poor stability and the risk of high-voltage wiring becoming detached. A simple, easy-to-use, and mechanically flexible three-phase busbar clamping mechanism could address these issues. Utility Model Content

[0019] like Figures 1 to 6 As shown, in this embodiment, the utility model includes a base plate 1, a clamp assembly 2 and a clamp assembly 3, the clamp assembly 2 includes a quick clamp 4 and a push plate 5, the quick clamp 4 is arranged on one side of the base plate 1, the push plate 5 is slidably matched with the base plate 1 through a plurality of first X-axis slide rails 6, the clamp assembly 3 includes a U-shaped guide plate 7, an insulating clamp module 8 and a conductive clamp module 9, the insulating clamp module 8 and the matching conductive clamp module 9 are respectively connected through the two movable ends of the second X-axis slide rail 27 Sliding in cooperation with the other side of the base plate 1, the insulating clamp module 8 and the conductive clamp module 9 are both provided with a roller 10 on the side away from each other. The movable end of the quick clamp 4 drives the inclined groove 11 on the push plate 5 to cooperate with the cam 12 on the U-shaped guide plate 7 to make the U-shaped guide plate 7 move back and forth in the Y-axis direction. The inclined surface 13 on the side corresponding to the guide end on both sides of the U-shaped guide plate 7 cooperates with the roller 10 to make the insulating clamp module 8 and the conductive clamp module 9 clamp or release the external copper busbar structure. It can be seen that the quick clamp 4 can drive the push plate 5 to move in the same direction, and drive the U-shaped guide plate 7 to move synchronously in the vertical direction through the inclined groove 11 and the cam 12. The inclined surface 13 slides over the outside of the insulating sliding plate 14 and the outside of the conductive sliding plate 19, and cooperates with the roller 10 to make the insulating sliding plate 14 and the conductive sliding plate 19 approach or separate from each other, thereby realizing the simultaneous clamping and conduction of the three interface ends of the external three-phase copper busbar, with a simple structure and higher efficiency.
[0020] like Figure 3 and Figure 5As shown, in this embodiment, the insulating clamping jaw module 8 includes an insulating sliding plate 14 and a plurality of insulating clamping jaws 15. The insulating sliding plates 14 are connected to the movable ends of the second X-axis slide rails 27. The insulating clamping jaws 15 slidably cooperate with the insulating sliding plate 14 via the third X-axis slide rails 16. Thus, the insulating clamping jaws 15 serve as auxiliary insulation clamping.
[0021] like Figures 3 to 5 As shown, in this embodiment, first baffles 17 are provided on both sides of the insulating sliding plate 14. The insulating clamping jaws 15 are limitedly engaged with the first baffles 17. A first buffer spring 18 is provided between the insulating clamping jaws 15 and the first baffle 17 on the side away from the conductive clamping jaw module 9. The roller 10 is provided on the outer side of the first baffle 17 on the side away from the conductive clamping jaw module 9. The roller 10 slides in engagement with the inclined surface 13 on the side corresponding to the U-shaped guide plate 7. Thus, the first buffer spring 18 provides a pressing buffer to prevent uneven force during the pressing process from causing overpressure.
[0022] like Figure 3 and Figure 6 As shown, in this embodiment, the conductive clamping jaw module 9 includes a conductive sliding plate 19 and a conductive clamping jaw 20. Several of the conductive sliding plates 19 are connected to the movable ends on the other side of several second X-axis slide rails 27. Several of the conductive clamping jaws 20 slide in conjunction with the upper end surfaces of several of the conductive sliding plates 19 via several fourth X-axis slide rails 21. Thus, it can be seen that the three sets of conductive clamping jaws 20 and three sets of insulating clamping jaws 15 can achieve compression and conduction of the three interface ends of the external three-phase copper busbar. The conductive sliding plates 19 and insulating sliding plates 14 are arranged at different sliding ends of the same set of slide rails and can achieve independent movement, so the pressing process will not interfere with each other.
[0023] like Figure 3 and Figure 6 As shown, in this embodiment, second baffles 22 are provided on both sides of the conductive sliding plate 19. The conductive clamping jaw 20 is limitedly engaged with the second baffles 22. A second buffer spring 23 is provided between the conductive clamping jaw 20 and the second baffle 22 on the side away from the insulating clamping jaw module 8. The second baffle 22 on the side away from the insulating clamping jaw module 8 is provided with the roller 10, and the roller 10 slides with the inclined surface 13 on the side corresponding to the U-shaped guide plate 7. It can be seen that the second buffer spring 23 provides a pressing buffer to prevent uneven force during the pressing process from causing overpressure.
[0024] like Figure 3As shown, in this embodiment, a plurality of Y-axis slide rails 24 are provided in the middle of the base plate 1, and the U-shaped guide plate 7 is connected to the movable ends of the plurality of U-axis slide rails 24. Thus, the Y-axis slide rails 24 make the U-shaped guide plate 7 move more stably in the Y-axis direction.
[0025] like Figure 3 As shown, in this embodiment, a plurality of third buffer springs 25 are provided between the conductive sliding plate 19 and the insulating sliding plate 14. Thus, the third buffer springs 25 act as secondary buffers during the pressing process to prevent overpressure.
[0026] like Figure 1 and Figure 2 As shown, in this embodiment, limit baffles 26 are provided at both ends of the other side of the base plate 1. The two sets of limit baffles 26 respectively cooperate with the insulating clamping jaw module 8 and the conductive clamping jaw module 9 to limit the position. As can be seen, the limit baffles 26 can prevent the insulating clamping jaw module 8 and the conductive clamping jaw module 9 from sliding out of the base plate 1.
[0027] The working principle of the present invention is as follows: before the equipment is started, the quick clamp 4 is in the open state, the three groups of insulating jaws 15 and the three groups of conducting jaws 20 are in the open state, and the three interface ends of the three-phase copper busbar to be tested are placed between the three groups of insulating jaws 15 and the three groups of conducting jaws 20. After the positioning is completed, the quick clamp 4 is pushed, and the push plate 5 drives the inclined surfaces 13 at both ends of the U-shaped guide plate 7 to contact the roller 10, so that the three groups of insulating jaws 15 and the three groups of conducting jaws 20 are close to each other and press the three-phase copper busbar. After the pressing is completed, the power-on test is carried out. After the test is completed, the quick clamp is opened, the three-phase copper busbar that has been tested is taken out, and the three-phase copper busbar to be tested is replaced. The above steps are repeated to realize the synchronous clamping and powering on of the three-phase copper busbar of the machine controller.
[0028] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
