DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1

[0028] Reference Figure 1-Figure 4 A grinding and chip suction device includes: a workbench 1 for stably supporting a new energy vehicle battery box to be processed. A support frame 3 is fixed on the top of the workbench 1 to support and stabilize the entire grinding system.

[0029] A slidable moving block 4 is designed at the bottom of the support frame 3. This moving block 4 is threadedly mounted on a screw 5 that extends through and rotates on one side of the support frame 3. The screw 5 is driven by a first motor 6 fixed to the side of the support frame 3. When the first motor 6 is activated, the screw 5 and the threads of the moving block 4 engage, allowing the moving block 4 to move horizontally under the support frame 3, thereby adjusting the position of the second electric push rod 28 and its associated structure at the bottom of the moving block 4, and therefore the overall position of the four grinding rods 12.

[0030] The second electric push rod 28 is fixed to the bottom of the moving block 4, and its output end is fixedly connected to a lifting frame 9, which is used to carry and control the up and down movement of the grinding rod 12. A guide rod 8 is fixed to the top of the lifting frame 9. The guide rod 8 passes through the waist-shaped hole 7 at the top of the support frame 3 and is slidably connected to the moving block 4 to ensure the stability and directionality of the lifting frame 9 during the lifting process.

[0031] Four grinding rods 12 are mounted on the lifting frame 9 and interconnected via a transmission mechanism for synchronous rotation. One of the grinding rods 12 is directly connected to the output of a second motor 14 on the lifting frame 9. When the second motor 14 is activated, it drives all four grinding rods 12 to rotate simultaneously, grinding the weld scars at the corners of the battery case.

[0032] To accommodate the grinding needs of corners of varying sizes, the lifting frame 9 is equipped with an adjustment mechanism. This adjustment mechanism comprises a gear 16 rotatably mounted within the lifting frame 9. Four arcuate holes 23 are defined at the top of the gear 16, while corresponding guide holes 24 are defined at the bottom of the lifting frame 9. A sliding seat 25 slides within each of these arcuate holes 23 and guide holes 24, with the grinding rods 12 extending and rotating within the sliding seat 25. A rack 17, meshing with the gear 16, is slidably mounted on one side of the lifting frame 9. The top of the rack 17 is connected to the top of the lifting frame 9 via a first electric push rod 15. When the first electric push rod 15 extends or contracts, the rack 17 rotates the gear 16. Since the gear 16 is connected to the sliding seat 25 via the arcuate holes 23 and guide holes 24, the rotation of the gear 16 translates into sliding movement of the sliding seat 25 within the guide holes 24, thereby adjusting the spacing between the four grinding rods 12.

[0033] In addition, to collect dust generated during the grinding process, four dust hoods 13 are installed at the bottom of the lifting frame 9. These dust hoods 13 are located on one side of the grinding rod 12 and provide some support for the grinding rod 12. The dust hoods 13 are connected to a dust box 10 located on the side of the lifting frame 9 via ducts. A dust collector 11 is installed on one side of the dust box 10. When the dust collector 11 is turned on, it draws dust from the dust hoods 13 into the dust box 10 through the ducts, effectively collecting and treating the grinding dust.

[0034] Synchronous wheels 20 are mounted on the outer walls of the sliding column 19 and the outer walls of the four grinding rods 12. The outer walls of these synchronous wheels 20 are connected by a common double-sided synchronous belt 21. When the double-sided synchronous belt 21 moves, it can drive all the synchronous wheels 20 to rotate synchronously, thereby achieving synchronous rotation of the four grinding rods 12.

[0035] At the top of the lifting frame 9, a mounting seat is slidingly provided, and the second motor 14 is fixedly mounted on the mounting seat. A clearance hole corresponding to the guide hole 24 is also provided on the top of the lifting frame 9 to allow the output end of the second motor 14 to pass through and make way for the structure in the guide hole 24. After the output end of the second motor 14 passes through the clearance hole, it is fixedly connected to one of the polishing rods 12, directly driving the polishing rod 12 to rotate. Due to the transmission effect of the double-sided synchronous belt, the other three polishing rods 12 will also rotate synchronously, and the second motor 14 will not be stuck with the lifting frame 9 when the polishing rod 12 moves, and the first motor 6, the second motor 14, the first electric push rod 15 and the second electric push rod 28 can be programmed and controlled by the controller, and a camera can be equipped at the bottom of the lifting frame 9 for precise control.

[0036] A tension spring 22 is sleeved on the outer wall of connecting rod 18. The ends of tension spring 22 are fixedly connected to the outer wall of sliding post 19 and one inner wall of lifting frame 9, respectively. The presence of tension spring 22 provides a continuous pulling force, keeping sliding post 19 and its connected synchronous wheel 20 in a fixed position, enhancing transmission stability and reliability.

[0037] This application can be used in the field of battery case processing, and can also be used in other fields applicable to this application.

[0038] Example 2

[0039] refer to Figure 1-Figure 5 , based on the improvement of Example 1: a grinding and chip suction device for processing battery boxes of new energy vehicles, which is applied to the field of battery box processing, a connecting rod 18 is fixedly installed inside the lifting frame 9. On the outer wall of the connecting rod 18, a sliding sleeve is provided with a sliding column 19, which can slide freely along the connecting rod 18.

[0040] The dust hood 13 is fixedly mounted on the bottom of the corresponding sliding seat 25, forming an integral structure with the sliding seat 25. A plurality of curved blocks 27 are fixedly mounted on the inner side of the dust hood 13. These curved blocks 27 correspond to and are located within the retaining grooves 26 defined on the outer wall of the polishing rod 12. The presence of these curved blocks 27 not only provides support for the polishing rod 12 but also enhances the stability of the connection between the dust hood 13 and the polishing rod 12.

[0041] A limit frame 2 is provided on top of the workbench 1 for positioning the battery case. The shape and size of the limit frame 2 are designed according to the actual shape and size of the battery case to ensure that the battery case can be accurately placed in the designated position, facilitating subsequent grinding and processing operations.

[0042] In the present application, when in use, the box is placed on the workbench 1 and positioned by the limit frame 2, and then the first motor 6 is started to drive the screw 5 to rotate. The rotation of the screw 5 can drive the lifting frame 9 to move through the guide rod 8 and the second electric push rod 28, and drive the lifting frame 9 to move to the connection of the reinforcing ribs. Then the second electric push rod 28 is started to extend, which can drive the lifting frame 9 to move downward. The downward movement of the lifting frame 9 can drive the grinding rod 12 to move downward, so that the grinding rod 12 moves to the corner of the connection, and the first electric push rod 15 is started to retract. The extension of the first electric push rod 15 can drive the rack 17 to move. The movement of the rack 17 can drive the gear 16 to rotate. The rotation of the gear 16 can pass through the arc hole 23 and the guide The cooperation of the hole 24 drives the sliding seat 25 to move inward, which can drive the grinding rod 12 to move inward, so that the multiple grinding rods 12 are close to each other. In the process of the grinding rod 12 approaching, the sliding column 19 can be driven to move by the tension spring 22. The movement of the sliding column 19 can drive the corresponding synchronous wheel 20 to move, thereby realizing the tensioning of the double-sided synchronous belt 21. At the same time, the corresponding mounting seat can be driven to move by the grinding rod 12, and the second motor 14 can be driven to move on the lifting frame 9. During the movement, the second motor 14 is started to drive the corresponding grinding rod 12 to rotate. In the process of the grinding rod 12 rotating, the remaining grinding rods 12 can be driven to rotate through the synchronous wheel 20 and the double-sided synchronous belt 21, so that the weld at the corner can be polished;

[0043] At the same time, the vacuum cleaner 11 is started. During the startup of the vacuum cleaner 11, the dust generated by grinding can enter the dust box 10 through the dust hood 13 and the pipe, so that the grinding situation can be easily observed.

[0044] After the grinding is completed, the second electric push rod 28 is started to retract, driving the lifting frame 9 to move upward. The upward movement of the lifting frame 9 can simultaneously drive multiple grinding rods 12 to move upward at the same time, and grind the ungrinded weld scars again until the grinding rods 12 are away from the box. Then the second motor 14 is turned off, and the first electric push rod 15 is started to extend and drive the gear 16 to reset and rotate, driving the four grinding rods 12 to reset and move.

[0045] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 6, the vacuum cleaner 11, the second motor 14, the first electric push rod 15 and the second electric push rod 28 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
