[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] This application discloses a measuring fixture for a new energy vehicle battery box, referring to... Figure 1 , Figure 2 and Figure 3 It includes a measuring frame 1, which is provided with multiple positioning pins 2 for inserting into positioning holes one by one, and a contoured groove 11 with a size adapted to the bottom of a standard battery box on the top of the measuring frame 1.

[0022] In this embodiment, the operator can lift the battery box to be measured onto the measuring frame 1 and lower it into the contour groove 11. During placement, it is necessary to ensure that the multiple positioning pins 2 can be inserted into the positioning holes one by one. If the bottom of the battery box can be smoothly inserted into the contour groove 11, it indicates that the bottom size of the battery box is qualified; if the bottom of the battery box cannot be inserted into the contour groove 11, it indicates that the bottom size of the battery box is unqualified. This new energy vehicle battery box measuring fixture can measure the dimensions of the bottom of the battery box, which has the effect of improving the yield rate of battery boxes leaving the factory.

[0023] Furthermore, a mounting frame 3 is provided on the outer side of the measuring frame 1. A frame 4 for placing the battery box is vertically slidably mounted on the mounting frame 3, and a clearance space is provided through the frame 4 for the measuring frame 1 to pass through. A conveyor 5 for transporting the battery box is provided on the outer side of the mounting frame 3. A notch 41 for the battery box to pass through horizontally is provided on the side of the frame 4 near the conveyor 5. A first driving member 6 is provided on the mounting frame 3 for moving the frame 4.

[0024] In this embodiment, the battery box is conveyed to the notch 41 of the frame 4 via the conveyor 5. Then, the operator can manually or with the aid of other equipment push it horizontally into the frame 4. The frame 4 then moves downwards so that the battery box rests on the positioning pin 2 or is directly inserted into the contour groove 11. When the battery box rests on the positioning pin 2, the operator can move the battery box so that the multiple positioning pins 2 can be inserted into the positioning holes one by one. This eliminates the need for operators to manually lift the battery box above the measuring frame 1, thus reducing the workload of the operators.

[0025] The first drive unit 6 includes multiple electric push rods, which are mounted on the mounting bracket 3, with the movable end of the electric push rods facing vertically upward and bolted to the frame 4.

[0026] In order to reduce the frictional force when the battery box enters the frame 4 horizontally, multiple rollers 7 are provided at intervals along the depth direction of the notch 41 on the bottom wall of the frame 4. All rollers 7 are rotatably connected to the bottom of the frame 4.

[0027] Furthermore, flexible pads 71 ​​are fitted onto the outer walls of multiple rollers 7.

[0028] In this embodiment, the flexible pad 71 is made of rubber, which can further reduce wear on the bottom of the battery box.

[0029] Reference Figure 4 The frame 4 has two clamping plates 8 that are horizontally and linearly slidably arranged inside, which are used to jointly clamp the two side walls of the battery box. The two side walls of the frame 4 are respectively provided with sliding grooves 42 for the clamping plates 8 to slide. The sliding grooves 42 are equipped with elastic members 9 for driving the clamping plates 8 to move and approach the battery box.

[0030] In this embodiment, the battery box is centered within the frame 4 by two clamps 8 that abut against both sides of the battery box, thus preventing the battery box from bumping against the side wall of the frame 4 during movement.

[0031] Specifically, a guide rod 91 is welded and fixed to the clamping plate 8. One end of the guide rod 91 extends through the side wall of the frame 4 and is welded with a stop block 92. The elastic element 9 is a spring, which is sleeved on the outer wall of the guide rod 91, and the two ends of the spring abut against the inner wall of the clamping plate 8 and the slide groove 42, respectively.

[0032] To facilitate the horizontal passage of the battery box through the notch 41 and into the frame 4, the clamping plate 8 has a chamfer 81 at one end near the notch 41.

[0033] Furthermore, a push plate 10 is slidably disposed inside the frame 4 along the depth direction of the notch 41 to abut against the battery box so that it moves out of the frame 4, and a second driving member 20 is provided on the frame 4 to drive the push plate 10 to move.

[0034] In this embodiment, after the battery box is measured, the frame 4 moves upward and aligns the notch 41 with the conveyor 5. Then, the push plate 10 is moved by the second drive member 20, which can push the battery box in the frame 4 onto the conveyor 5, and then the conveyor 5 transports it, which can further reduce the labor intensity of the staff.

[0035] The second drive component 20 adopts a rodless cylinder, which includes a cylinder body and a slide. The cylinder body is horizontally set on the frame 4, and the slide is bolted to the push plate 10.

[0036] The implementation principle of the battery box measurement fixture for new energy vehicles in this application embodiment is as follows: The operator can lift the battery box to be measured onto the measuring frame 1 and lower it into the contour groove 11. During placement, it is necessary to ensure that multiple positioning pins 2 can be inserted into the positioning holes one by one. If the bottom of the battery box can be smoothly inserted into the contour groove 11, it indicates that the bottom size of the battery box is qualified; if the bottom of the battery box cannot be inserted into the contour groove 11, it indicates that the bottom size of the battery box is unqualified. This method improves the yield rate of battery boxes leaving the factory.
