Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, and in particular to an adjustable drilling device for processing automotive sheet metal parts. Background Technology

[0002] In modern automotive production, the processing of sheet metal parts often requires drilling holes to facilitate connections between components and other parts. Existing mechanical drilling equipment typically uses hydraulic or pneumatic cylinders to drive the drill bit, or an electric motor to drive the drill bit, to drill holes in the sheet metal parts. During drilling, the sheet metal part is placed under the drilling equipment, and then clamps are used to hold and fix the sheet metal part in place.

[0003] For example, Chinese Patent Publication No. CN220533028U discloses a drilling device for automotive sheet metal parts, relating to the field of drilling equipment technology. The device includes a frame, a support beam, and an equipment box. The equipment box houses a drilling mechanism, which includes a motor, a support frame, a drill bit, and a stabilizing component. The stabilizing component includes pressure rods and connecting members. There are at least two pressure rods, and the connecting members connect the two pressure rods. The drill bit is located between the two pressure rods. From top to bottom, each pressure rod consists of a connecting part, a spring part, and a pressure head. The top of the connecting part is connected to the support frame.

[0004] However, in the above solution, it is not convenient to quickly replace the drilling bit when using the device. When the drilling bit needs to be replaced, it needs to be replaced manually by the staff, which is time-consuming and laborious, and affects the drilling efficiency of sheet metal parts.

[0024] Please see Figure 1-4 In this embodiment of the present invention, an adjustable drilling device for processing automotive sheet metal parts includes a worktable 1, four support legs 2 fixedly connected to the bottom of the worktable 1, a clamping structure on the top of the worktable 1, a housing 7 fixedly connected to the top of the worktable 1, an electric push rod 8 fixedly connected to the bottom of the housing 7, a mounting plate 6 fixedly connected to the extended end of the electric push rod 8, a drilling motor 10 fixedly connected to the bottom of the mounting plate 6, a gear disk 13 connected to one end of the drilling motor 10 through a transmission structure, a limiting structure on the top of the gear disk 13, an adjusting motor 5 fixedly connected to the bottom of the mounting plate 6, an adjusting gear 4 fixedly connected to one end of the output shaft of the adjusting motor 5, and the adjusting gear 4 meshing with the gear disk 13.

[0025] Please see Figure 1-2 The clamping structure includes a base plate 15, which is fixedly connected to the top side wall of the workbench 1. Two L-shaped plates 19 are fixedly connected to the top of the base plate 15. Support plates 16 are fixedly connected to the side walls of the two L-shaped plates 19. Bolts 17 are threadedly connected to the top of the two L-shaped plates 19. The bottom of the two bolts 17 passes through the L-shaped plates 19 and is rotatably connected to the pressing plates 18. The bottom of the two pressing plates 18 is provided with anti-slip pads. By placing the sheet metal part on the top of the two support plates 16 and rotating the two bolts 17, the two bolts 17 can drive the two pressing plates 18 to move downwards, thereby clamping and fixing the two ends of the sheet metal part.

[0026] Please see Figure 1-3 The transmission structure includes a drive gear 11, which is fixedly connected to the output shaft of the drilling motor 10. The bottom of the drive gear 11 is rotatably connected to the top side wall of the gear disk 13. Four rotating rods 14 are rotatably connected to the side wall of the gear disk 13. The four rotating rods 14 are arranged in a circular array. Each rotating rod 14 has a driven gear 12 fixedly connected to its top. Each driven gear 12 meshes with the drive gear 11. The bottom of each rotating rod 14 passes through the gear disk 13. Each rotating rod 14 has a drill bit 3 at its bottom. By starting the drilling motor 10, the drive gear 11 is driven to rotate. When the drive gear 11 rotates, it can drive the four driven gears 12 to rotate simultaneously. The four driven gears 12 drive the drill bit 3 to rotate through the rotating rods 14.

[0027] Please see Figure 1-4The limiting structure includes an electric telescopic rod 9, which is fixedly connected to the bottom side wall of the mounting plate 6. A conical head 21 is fixedly connected to the extended end of the electric telescopic rod 9. The top of the gear disk 13 has four conical holes 20, which are located next to four rotating rods 14. The conical head 21 is located in one of the conical holes 20. By activating the electric telescopic rod 9, the electric telescopic rod 9 drives the conical head 21 out of one of the conical holes 20. Then, by activating the adjusting motor 5, the adjusting gear 4 can be rotated. The adjusting gear 4 can drive the gear disk 13 to rotate, so that the drill bits 3 of different diameters are positioned above the sheet metal part. Then, by activating the electric telescopic rod 9, the conical head 21 is driven into one of the conical holes 20, thereby fixing the gear disk 13.

[0028] The working principle of this utility model is as follows: The sheet metal part is placed on top of two support plates 16. By rotating two bolts 17, the two bolts 17 can drive two pressing plates 18 to move downwards, thereby clamping and fixing both ends of the sheet metal part. Then, the drilling motor 10 is started, driving the drive gear 11 to rotate. The drive gear 11, when rotating, drives four driven gears 12 to rotate simultaneously. The four driven gears 12 drive the drill bit 3 to rotate via the rotating rod 14. Then, the electric push rod 8 is started, driving the drilling motor 10 to move downwards, thereby drilling a hole in the sheet metal part through one of the drill bits 3. By activating the electric telescopic rod 9, the conical head 21 is disengaged from one of the conical holes 20. Then, the adjusting motor 5 is activated to rotate the adjusting gear 4, which in turn rotates the gear disk 13. This allows drill bits 3 of different diameters to be positioned above the sheet metal part. Then, by activating the electric telescopic rod 9, the conical head 21 is driven into one of the conical holes 20, thus fixing the gear disk 13. With multiple drill bits 3, the gear disk 13 can be rotated as needed to position drill bits 3 of different diameters above the sheet metal part, making it easier to drill through holes of different diameters into the sheet metal part.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
