Description

Electric vehicle rear rack edge grinding device Technical Field

[0001] This utility model relates to the field of rear rack polishing technology, and in particular to a device for polishing the edge of the rear rack of an electric vehicle. Background Technology

[0002] In the electric vehicle manufacturing and repair industry, the rear rack of an electric vehicle is an important accessory, and the edge polishing treatment has a crucial impact on the quality and safety of the product. As the electric vehicle market continues to expand, the requirements for the production efficiency and polishing quality of the rear rack are also increasing. However, the traditional edge polishing method for electric vehicle rear racks has many drawbacks and is difficult to meet the needs of modern production.

[0003] Traditional electric vehicle rear rack edge polishing devices rely on manual labor to place each rear rack to be polished in a designated position before a mechanical gripper grasps and polishes it. This method requires workers to constantly monitor the operation process, resulting in high labor intensity and low efficiency. If workers are negligent, the rear rack may be placed in an inaccurate position, affecting the polishing quality and potentially damaging the polishing equipment. Moreover, manual operation makes it difficult to ensure that the rear rack is placed in the same position every time, resulting in inconsistent polishing effects and affecting the overall quality of the rear rack.

[0004] To improve the production efficiency and quality of electric vehicle rear racks, developing an edge polishing device that can reduce the frequency of worker loading and minimize manual intervention has become a problem that needs to be solved in the electric vehicle manufacturing industry. Summary of the Invention

[0005] In view of the above, in order to improve the production efficiency and quality of electric vehicle rear racks, it is necessary to develop an edge grinding device that can reduce the frequency of worker loading and reduce manual intervention, which has become a problem that needs to be solved in the electric vehicle manufacturing industry. Therefore, this utility model is proposed.

[0006] Therefore, the purpose of this invention is that when the abutting movable plate is in its initial position, the fixed connecting block is fixed on the guide constraint column and abuts against the constraint connecting plate. The moving teeth rotate to mesh with the fixed tooth groove on the fixed connecting block. The movement of the fixed connecting block will drive the abutting movable plate to move along the direction of the guide constraint column, thereby positioning the hanger to be sanded. When the hanger to be sanded has moved to the completed positioning, the rotating belt continues to rotate, causing the rotating teeth to disengage from the fixed tooth groove on the fixed connecting block. The abutting movable plate returns to its initial position, ready for the next loading operation. This device can reduce the frequency of worker loading, reduce manual intervention, thereby reducing insufficient sanding precision caused by manual labor during the sanding process and improving sanding quality.

[0028] Example 1

[0029] Referring to Figures 1-4, the first embodiment of this utility model provides an electric vehicle rear rack edge grinding device, including a limiting fixing plate 1 and a limiting baffle 2 on one side of the limiting fixing plate 1. A limiting constraint rail 3 is provided on one side of the limiting baffle 2, and multiple rear racks 5 to be ground are provided inside the limiting constraint rail 3. It includes an abutting movable plate 6 installed on one side of the limiting fixing plate 1, and two guide constraint posts 7 are provided on one side of the abutting movable plate 6. A constraint connecting plate 13 is provided on the limiting fixing plate 1. One end of the two guide constraint posts 7 passes through the constraint connecting plate 13 and is suspended. An arc-shaped fixing plate 4 is provided on one side of the limiting fixing plate 1. The rear racks 5 to be ground are provided between the abutting movable plate 6 and the arc-shaped fixing plate 4. A fixing connecting block 8 is provided on the limiting fixing plate 1, and the fixing connecting block 8 is fixed on the two guide constraint posts 7.

[0030] Two fixed connection slots 9 are provided on the fixed connection block 8, and two fixed insertion blocks 12 are provided on the limiting fixed plate 1. Each fixed insertion block 12 is connected to the limiting baffle 2. The two fixed insertion blocks 12 are located inside the corresponding fixed connection slots 9. A fixed tooth groove 10 is provided on one side of the fixed connection block 8. A rotating connection slot 22 is provided on the limiting fixed plate 1. Two constraint baffles 15 are provided inside the rotating connection slot 22. Two rotating constraint columns 16 are provided between the two constraint baffles 15.

[0031] Example 2

[0032] Referring to Figures 3-6, this is the second embodiment of the present invention. This embodiment differs from the first embodiment in that it includes a fixed connecting plate 11 installed on one side of the limiting constraint bar 3. Two reset connecting rods 24 are provided on one side of the fixed connecting plate 11. A reset spring 25 is sleeved on each reset connecting rod 24. A rotating motor 17 is provided on one side of the limiting baffle 2. One side of the rotating motor 17 is connected to a corresponding rotating constraint post 16. A rotating belt 18 is sleeved on the two rotating constraint posts 16. Two rotating teeth 19 are provided on the rotating belt 18.

[0033] One end of the rotating tooth 19 is inserted into the inner side of the corresponding fixed tooth groove 10. A reset connecting block 23 is provided on one side of the fixed connecting block 8. A reset spring 25 is provided between the fixed connecting plate 11 and the reset connecting block 23. One end of the two reset connecting rods 24 passes through the constraint connecting plate 13 and is suspended in the air. The two reset connecting rods 24 are movably inserted into the inner side of the reset connecting block 23. A constraint connecting groove 14 is opened on one side of the constraint connecting plate 13. A reserved clamping groove 20 is opened on the limit baffle 2. Multiple fixed support plates 21 are provided on one side of the limit fixing plate 1.

[0034] Before the polishing device is started, multiple hangers 5 to be polished are placed inside the limiting constraint bar 3. The limiting fixing plate 1 and the limiting baffle 2 provide stable support and limiting foundation for the entire device. The fixed support plate 21 on the limiting fixing plate 1 is used to support the entire device and ensure its stability during operation. When the abutting movable plate 6 is in the initial position, the fixed connecting block 8 is fixed on the guide constraint column 7.

[0035] The rotating teeth 19 abut against the constraint connecting plate 13, which is achieved by the return spring 25 pressing the return connecting block 23. At this time, the rotating teeth 19 are not engaged with the fixed teeth 10 on the fixed connecting block 8. The rotating motor 17 is started, and the rotating motor 17 drives the rotating constraint column 16 connected to it to rotate. The rotating belts 18 sleeved on the two rotating constraint columns 16 rotate accordingly, and the rotating teeth 19 on the rotating belts 18 also rotate together.

[0036] When the rotating tooth 19 rotates to mesh with the fixed tooth groove 10 on the fixed connecting block 8, the rotation of the rotating belt 18 will drive the fixed connecting block 8 to move. Since the fixed connecting block 8 is fixed on the guide constraint post 7, and the guide constraint post 7 is connected to the abutting movable plate 6, the movement of the fixed connecting block 8 will drive the abutting movable plate 6 to move along the direction of the guide constraint post 7. When the abutting movable plate 6 moves, it will push the hanger 5 to be polished inside the limit constraint bar 3 to move towards the arc-shaped fixed plate 4.

[0037] The design of the arc-shaped fixing plate 4 can assist the hanger 5 to be sanded in positioning, so that it gradually reaches the accurate sanding position during the movement. During this process, the hanger 5 to be sanded achieves automatic feeding and positioning under the action of the movable plate 6 and the arc-shaped fixing plate 4. When the hanger 5 to be sanded moves to the completed positioning, the rotating belt 18 continues to rotate, so that the rotating teeth 19 disengage from the fixed tooth groove 10 on the fixed connecting block 8.

[0038] At this time, under the action of the reset spring 25, the reset connecting block 23 pushes the fixed connecting block 8 to abut against the constraint connecting plate 13 again, and the abutting movable plate 6 returns to the initial position, ready to carry out the next loading operation. After the hanger 5 to be polished is positioned, the mechanical claw clamps it through the reserved clamping groove 20 on the limit baffle 2, and the mechanical claw moves the hanger 5 to be polished to the polishing area for edge polishing.

[0039] After the polishing is completed, the mechanical gripper removes the polished hanger. At this time, the device repeats the above feeding process again, pushing the next hanger 5 to be polished in the limit constraint bar 3 to the designated position, where it is held by the mechanical gripper for polishing. This cycle repeats to achieve continuous automatic feeding and polishing operations.

[0040] The remaining structure is the same as that in Example 1.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
