Description

Technical Field

[0001] This utility model relates to the field of new energy vehicles, and in particular to a grinding device for producing aluminum shells for battery boxes. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0003] When electric-driven new energy vehicles are manufactured, their batteries need to be installed in conjunction with battery boxes. To ensure the stability of the battery boxes, some battery boxes are equipped with an aluminum outer shell structure to improve the safety of the battery boxes.

[0004] After the aluminum shell structure of the battery box is produced and welded, there will be weld scars or burrs on its surface. In addition, most of the aluminum shells of the battery box are not flat plate structures. Most existing grinding equipment is not easy to grind the vertical end faces of the grooves or through slots of the aluminum shell structure of the battery box during operation. Utility Model Content

[0005] The purpose of this invention is to provide a grinding device for the production of aluminum casings for battery boxes in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A grinding device for producing aluminum casings for battery boxes includes a base, with columns fixed at the four corners of the upper end of the base, a clamping mechanism installed at the upper end of the base, and a grinding mechanism.

[0008] The grinding mechanism includes an adjustment structure, which is installed at the upper end of the four columns, and the grinding structure is installed at the lower end of the adjustment structure.

[0009] The grinding structure includes a lifting plate, which is located at the lower end of the adjustment structure. Both ends of the lifting plate are fixed with fixing rings, and a rotating frame is rotatably connected between the two fixing rings. Springs are fixed inside the upper and lower ends of the rotating frame, and a locking block is fixed to one end of each spring. A loading frame is slidably connected inside the rotating frame, and a third motor is installed inside the loading frame. A grinding disc is fixed to the output end of the third motor.

[0010] Preferably, the outer ring of the fixing ring has multiple through holes corresponding to the locking block, and the positions of the through holes on the two fixing rings are corresponding.

[0011] Preferably, the adjustment structure includes a first screw, which is rotatably connected between two columns at the rear end. A first motor is installed at the input end of the first screw, and a second guide rod is fixed between the two columns at the front end. A sliding frame is slidably connected to the rear end of the second guide rod, and the sliding frame is threadedly connected to the first screw.

[0012] Preferably, a second screw is rotatably connected to the lower end of the sliding frame, a second motor is installed at the input end of the second screw, a slider is threadedly connected to the outer side of the second screw, and the slider is slidably connected to the sliding frame, with an electric actuator installed at one end of the slider.

[0013] Preferably, the clamping mechanism includes a bidirectional screw, which is rotatably connected between two of the columns, and a first guide rod is fixed between the other two columns. One end of the first guide rod is slidably connected to two clamping plates, and the two clamping plates are threadedly connected to the bidirectional screw.

[0014] Preferably, a throttle is fixed at the input end of the bidirectional screw, and rubber layers are provided at the corresponding ends of the two clamping plates.

[0015] The advantages compared to existing technologies are as follows:

[0016] When the device is in operation, the third motor drives the grinding disc to rotate, and the adjustment structure moves the grinding structure, so that the grinding disc can grind the flat structure of the aluminum shell of the battery box. When it is necessary to grind the vertical end face of the aluminum shell, the spring elasticity first presses the locking blocks at the upper and lower ends of the rotating frame into the rotating frame, so that the rotating frame is not limited. Then, the rotating frame is rotated 90 degrees clockwise or counterclockwise so that the locking blocks are locked into the corresponding through holes of the outer ring of the fixing ring, so that the rotating frame cannot rotate. In this way, the grinding end of the grinding disc is set vertically, so that the device can grind the vertical end face of the aluminum shell. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-5 As shown, a grinding device for producing aluminum casings of battery boxes includes a base 1, with columns 11 fixed at the four corners of the upper end of the base 1, a clamping mechanism installed on the upper end of the base 1, and a grinding mechanism.

[0028] The clamping mechanism includes a bidirectional screw 2, with a throttle fixed to the input end of the bidirectional screw 2. The bidirectional screw 2 is rotatably connected between two columns 11, and a first guide rod 21 is fixed between the other two columns 11. Two clamping plates 22 are slidably connected to one end of the first guide rod 21. Each end of the two clamping plates 22 has a rubber layer, and the two clamping plates 22 are threadedly connected to the bidirectional screw 2. Through the sliding connection between the two clamping plates 22 and the first guide rod 21, and the threaded connection between the clamping plates 22 and the bidirectional screw 2, the two clamping plates 22 can clamp the aluminum shell of the battery box when the bidirectional screw 2 is rotated.

[0029] The grinding mechanism includes an adjustment structure installed at the upper end of four columns 11. The grinding structure is installed at the lower end of the adjustment structure. The adjustment structure includes a first screw 3, which is rotatably connected between the two rearmost columns 11. A first motor 31 is installed at the input end of the first screw 3. A second guide rod 32 is fixed between the two frontmost columns 11. A sliding frame 33 is slidably connected to the rear end of the second guide rod 32 and is threadedly connected to the first screw 3. A second screw 34 is rotatably connected to the lower end of the sliding frame 33. A second motor 35 is installed at the input end of the second screw 34. A slider 36 is threadedly connected to the outer periphery of the second screw 34 and is slidably connected to the sliding frame 33. An electric push rod 37 is installed at one end of the slider 36. The grinding structure includes a lifting plate 38, which is fixed to the lower end of the electric push rod 37. Both ends of the lifting plate 38 are fixed with fixing rods. A rotating frame 310 is rotatably connected between two fixed rings 39. Springs 311 are fixed inside the upper and lower ends of the rotating frame 310. A locking block 312 is fixed to one end of each spring 311. A loading frame 313 is slidably connected inside the rotating frame 310. A third motor 314 is installed inside the loading frame 313. A grinding disc 315 is fixed to the output end of the third motor 314. Through the threaded connection between the sliding frame 33 and the first screw 3 and the sliding connection between the sliding frame 33 and the second guide rod 32, the sliding frame 33 can move when the first motor 31 drives the first screw 3 to rotate. Through the threaded connection between the slider 36 and the second screw 34 and the sliding connection between the slider 36 and the sliding frame 33, the slider 36 can move when the second motor 35 drives the second screw 34 to rotate. In this way, the grinding position of the grinding disc 315 can be adjusted.

[0030] Working principle: During device operation, the aluminum outer shell of the battery box is first placed between two clamping plates 22. Then, through the sliding connection between the two clamping plates 22 and the first guide rod 21, and the threaded connection between the clamping plates 22 and the bidirectional screw 2, rotating the bidirectional screw 2 clamps the aluminum outer shell of the battery box. After clamping, the electric push rod 37 drives the lifting plate 38 to descend, causing the lower end face of the grinding disc 315 to contact the upper end face of the aluminum outer shell of the battery box. Then, the third motor 314 is activated to grind the flat structure of the aluminum outer shell of the battery box using the grinding disc 315. Simultaneously, the first motor 31 and the second motor 35 are activated. Through the threaded connection between the sliding frame 33 and the first screw 3, and the sliding connection between the sliding frame 33 and the second guide rod 32, when the first motor 31 drives the first screw 3 to rotate, it can... The sliding frame 33 is moved by the threaded connection between the slider 36 and the second screw 34, and the sliding connection between the slider 36 and the sliding frame 33. When the second motor 35 drives the second screw 34 to rotate, the slider 36 can be moved. This allows the grinding position of the grinding disc 315 to be adjusted. When the vertical end face of the aluminum shell needs to be ground, the spring 311 first presses the locking blocks 312 at the upper and lower ends of the rotating frame 310 into the rotating frame 310, so that the rotating frame 310 is not limited. Then, the rotating frame 310 is rotated 90 degrees clockwise or counterclockwise so that the locking blocks 312 are locked into the corresponding through holes on the outer ring of the fixing ring 39, so that the rotating frame 310 cannot rotate. This allows the grinding end of the grinding disc 315 to be set vertically, so that the device can grind the vertical end face of the aluminum shell.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
