[0002] Battery trays are an important component of the power system of new energy vehicles. Their main function is to carry and protect the power battery. Battery trays are usually made of aluminum alloy. Due to its high strength, light weight, and strong corrosion resistance, it has become the preferred material for new energy vehicle battery trays. During the processing of battery trays, drilling equipment is required to drill holes in them.

[0056] The implementation principle of the drilling device and method for aluminum profiles of battery trays for new energy vehicles according to the embodiment of the present invention is as follows: first, two battery tray bodies 5 to be drilled are placed in two assembly frames 4, and then the first motor 6 is started to drive the first screw 7 to rotate, and the movable frame 2 drives the assembly frame 4 to move to the right on the guide frame 8, and drives the driving frame 11 to slide to the right in the driving groove 14 of the horizontal plate 13, and drives the driving frame 11 through the driving groove 14, pulling the driving plate 10 to move downward on the fixed seat 9, and drives the two assembly frames 4 through the two first gears 12. The frame 4 rotates, thereby driving the two battery tray bodies 5 to be assembled together. During the rotation of the assembling frame 4, the roller 21 at one end of the tightening rod 16 is driven to roll onto the inclined portion 24, thereby pushing the tightening rod 16 to drive the tightening plate 17 to move. The tightening plate 17 presses the battery tray body 5 to the inner wall of one side of the assembling frame 4 for fixation, avoiding the problem that the battery tray body 5 moves or even falls during the rotation of the assembling frame 4, so that the two battery tray bodies 5 can be smoothly assembled together. When the mobile frame 2 drives the battery tray body 5 to move to When the fixing frame 25 is in position, the second motor 31 is started to drive the second screw rod 32 to rotate, and the movable plate 29 moves on the rotating second screw rod 32, thereby driving the drill rod 34 to move to the edge of the battery tray body 5, and the third motor 33 is started to drive the drill rod 34 to drill the battery tray body 5. At the same time, through the second gear 35 and the third gear 37, the drill rod 34 drives the cleaning rod 38 to rotate when it rotates, so that when the rotating cleaning rod 38 is inserted into the drilled hole, the bristles on the cleaning rod 38 can be used to clean the debris in the drilled hole. Automatic hole cleaning is performed. After drilling, the mobile frame 2 moves to the rightmost position, and by utilizing the sliding of the driving frame 11 in the driving groove 14, the driving plate 10 can be driven to move upward on the fixed seat 9 during the process of the mobile frame 2 moving to the right, thereby automatically opening the two assembly frames 4, and during the rotation of the assembly frame 4, the bottom of the battery tray main body 5 is driven to be squeezed onto the push block 41. As the assembly frame 4 continues to rotate, the battery tray main body 5 can be automatically pushed out from the assembly frame 4, and finally the battery tray main body 5 after drilling can be taken out from the assembly frame 4.
