New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles.

[0003] In existing technologies, when processing battery frames, drilling is required. First, the battery frame needs to be fixed by a clamping fixture. The clamping fixture can firmly fix the battery frame on the processing table to prevent it from shifting or shaking during the drilling process. However, the position of the battery frame needs to be changed during the drilling process. For example, the tooling can only clamp the battery frame from the longitudinal position. Due to the change in position, when clamping laterally, the overall tooling's lateral clamping capacity may be limited, making it impossible to quickly and stably achieve effective fixation in the lateral direction.

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-point positioning fixture for the battery frame of a new energy vehicle.

[0009] In a preferred embodiment, a connecting rod is provided on the inner wall of the horizontal plate, and the inner wall of the horizontal plate is slidably connected to the outer side of the connecting rod. A spring is provided at one end of the connecting rod, and one end of the connecting rod is fixedly connected to one end of the spring.

[0010] In a preferred embodiment, one end of the connecting rod is fixedly connected to one side of the inner plate.

[0011] In a preferred embodiment, a fixed plate is provided at the center of the bottom side of the processing table, and the center of the bottom side of the processing table is rotatably connected to the top of the fixed plate. A movable arm is provided on the inner side of one end of the protrusion of the fixed plate, and the inner side of one end of the protrusion of the fixed plate is rotatably connected to one end of the movable arm.

The bottom end of the extrusion plate 112 is threadedly connected to the outer side of the lead screw 113. One end of the lead screw 113 is rotatably connected to one top end of the side plate 17. The inner wall of the side plate 17 is slidably connected to the bottom end of the slide rail. The top end of the slide rail is fixedly connected to the bottom side of the extrusion plate 112. A horizontal plate 19 is provided on one side of the side plate 17. One side of the side plate 17 is fixedly connected to one end of the horizontal plate 19. A connecting rod is provided on the inner wall of the horizontal plate 19. 110. The inner wall of the horizontal plate 19 is slidably connected to the outer side of the connecting rod 110. A spring 111 is provided at one end of the connecting rod 110, and one end of the connecting rod 110 is fixedly connected to one end of the spring 111. The other end of the spring 111 is fixedly connected to one side of the horizontal plate 19. One end of the connecting rod 110 is fixedly connected to one side of the inner plate 18. A fixed plate 12 is provided at the center of the bottom side of the processing table 11. The center of the bottom side of the processing table 11 is rotatably connected to the top of the fixed plate 12. A movable arm 13 is provided on the inner side of one end of the protrusion of the fixed plate 12. One end of the starting point is rotatably connected to one end of the movable arm 13, and the other end of the movable arm 13 is rotatably connected to the bottom end of the slide plate 14. A motor 15 is provided at the center of the bottom side of the fixed plate 12, and the output end of the motor 15 is fixedly connected to the center of the bottom side of the fixed plate 12. A base plate 16 is provided at the bottom end of the motor 15, and the bottom end of the motor 15 is fixedly connected to the top side of the middle end of the base plate 16. A support column 115 is provided at one end of the base plate 16, and one end of the base plate 16 is fixedly connected to one side of the bottom end of the support column 115. The top end of the support column 115 is fixedly connected to the bottom side of one end of the processing table 11.

[0022] In this embodiment, when using this type of multi-point positioning fixture for new energy vehicle battery frames, a fixed plate 12 is installed on the bottom side of the middle of the processing table 11. The fixed plate 12 has two protrusions, and movable arms 13 are rotatably connected to the inner sides of the two protrusions. The two movable arms 13 are oriented in different directions, but are both connected to the bottom side of the sliding plate 14. The two sliding plates 14 are respectively designed to be at both ends of the processing table 11. The sliding plates 14 can change position during the rotation of the fixed plate 12, thereby shortening the distance between the two sliding plates 14. Side plates 17 are then installed at the top of each of the two sliding plates 14. The components designed on each side plate 17 are identical. The side plate 17 is L-shaped, with the shorter end serving as the clamping surface. The battery frame is positioned horizontally between the two battery frames. By starting the motor 15, the fixed plate 12 begins to rotate. The rotation of the fixed plate 12 will drive the two movable arms 13 connected to it to rotate synchronously. Since the two movable arms 13 are facing different directions, during the rotation, they will exert a pulling force on the connected slide plate 14, causing the slide plate 14 to move towards each other along both ends of the processing table 11, shortening the distance between the two slide plates 14, thereby clamping the battery frame between the two side plates 17. An inner plate 18 is designed on the clamping surface of the side plate 17. The inner plate 18 is located on the inner wall of the side plate 17 in a fitting manner, and the inner plate 18 is T-shaped with a bevel at the longer end. A pressing plate 112 is designed on one side of the bevel. The pressing plate 112 is in contact with the bevel of the inner plate 18. A lead screw 113 is designed on the bottom side of the pressing plate 112. The lead screw 113 is connected to the top side of the side plate 17. Then, by rotating the lead screw 113, the pressing plate 112 moves. During the movement, it will exert an external force on the inner plate 18 to one side, causing the inner plate 18 to slide out from the inner wall of the side plate 17. In this way, when clamping the battery frame longitudinally, it can adapt to the longitudinal clamping requirements of the battery frame and can perform multi-point positioning clamping of the battery frame from both the horizontal and vertical dimensions. In this way, whether drilling or welding, the multi-dimensional clamping and fixing can ensure that the battery frame always maintains the preset positional accuracy. A horizontal plate 19 is installed on one side of the side plate 17. A connecting rod 110 is designed on the inner wall of the horizontal plate 19. One end of the connecting rod 110 is fixed to one side of the inner plate 18. At the same time, a spring 111 is designed between the connecting rod 110 and the horizontal plate 19. When the inner plate 18 is not subjected to external force, the spring 111 uses its own release ability to reset the inner plate 18. Meanwhile, the connecting rod 110 can provide effective path support for the inner plate 18 during its sliding, so as to avoid the skew. A guide rail 114 is designed on the bottom side of the extrusion plate 112. The outer side of the bottom end of the guide rail 114 can slide on the inner wall of the side plate 17. When the extrusion plate 112 moves, the guide rail 114 will slide synchronously along the inner wall of the side plate 17, providing a stable guiding effect for the extrusion plate 112 and ensuring that the extrusion plate 112 always applies external force to the inner plate 18 in a preset direction. Example

[0023] like Figures 1-4 As shown, the indicating mechanism 2 includes a scale 21, a finger rod 22 is provided on the inner side of the scale 21, the inner side of the scale 21 slides corresponding to one end of the finger rod 22, the other end of the finger rod 22 is provided with a guide rail 114, the other end of the finger rod 22 is fixedly connected to the inner side of the guide rail 114, and one end of the scale 21 is fixedly connected to one end of the slide plate 14.

[0024] In this embodiment, a scale 21 is installed at one end of the processing table 11. A finger rod 22 is designed on the inner side of the scale 21. The finger rod 22 can slide on the inner side of the scale 21. The finger rod 22 is fixed on the inner side of the guide rail 114. Thus, the moving distance of the extrusion plate 112 can be read intuitively by the sliding position of the finger rod 22 on the inner side of the scale 21. The operator only needs to observe the value pointed to by the finger rod 22 on the scale 21. This ensures that the lengths of the two inner plates 18 are consistent after sliding out, so that the longitudinal clamping force of the inner plates 18 on both sides of the battery frame remains balanced. Since the extension lengths of the inner plates 18 on both sides are the same, the contact position and contact area with the longitudinal side of the battery frame are completely symmetrical, effectively avoiding the battery frame from shifting due to uneven force.

[0025] Working principle: like Figures 1-5 As shown, the battery frame is positioned horizontally between two battery frames. By starting the motor 15, the fixed plate 12 begins to rotate. The rotation of the fixed plate 12 will drive the two connected movable arms 13 to rotate synchronously. Since the two movable arms 13 are facing different directions, they will exert a pulling force on the connected sliding plate 14 during the rotation, causing the sliding plate 14 to move towards each other along both ends of the processing table 11, shortening the distance between the two sliding plates 14, thereby clamping the battery frame between the two side plates 17. Next, by rotating the lead screw 113, the pressing plate 112 moves. During the movement, it will exert an external force on the inner plate 18 to one side, causing the inner plate 18 to slide out from the inner wall of the side plate 17. In this way, when clamping the battery frame vertically, it can adapt to the vertical clamping requirements of the battery frame and perform all-round multi-point positioning clamping of the battery frame from both horizontal and vertical dimensions. A scale 21 is installed at one end of the processing table 11. A finger rod 22 is designed on the inner side of the scale 21. The finger rod 22 can slide on the inner side of the scale 21. The finger rod 22 is fixed on the inner side of the guide rail 114. The movement distance of the extrusion plate 112 can be read intuitively by the sliding position of the finger rod 22 on the inner side of the scale 21. This ensures that the lengths of the two inner plates 18 are consistent after sliding out, so that the longitudinal clamping force of the two inner plates 18 on the battery frame is balanced.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
