[0024] Please see Figure 1-4This utility model discloses a drilling device for processing electric bicycle frames, including a processing table 1, a base 2, a clamping seat 5, and a front fork body 4. The base 2 is fixed to the upper end of the processing table 1, and the base 2 is provided with a placement groove 3. The front fork body 4 is placed in the placement groove 3. The clamping seat 5 is located above the base 2, and the lower end of the clamping seat 5 is provided with a clamping groove 6 that cooperates with the front fork body 4. The lower end of the processing table 1 is provided with a first lifting component 7, and the output end of the first lifting component 7 is provided with a lifting rod connected to the clamping seat 5. The base 2 can be replaced on the processing table 1, and the clamping seat 5 can be replaced at the top of the lifting rod.

[0025] A second lifting assembly 8 is fixedly installed above the processing table 1. The output end of the second lifting assembly 8 is provided with a frame 9. The bottom end of the frame 9 is provided with a support plate 10. The support plate 10 is provided with a first top plate 11 and a second top plate 12. The positions of the first top plate 11 and the second top plate 12 can be adjusted on the support plate 10. The lower end of the first top plate 11 is provided with a first motor 14. The output end of the first motor 14 is provided with a first drill bit 15. The lower end of the second top plate 12 is symmetrically provided with two bent rods 18. The bottom end of the bent rods 18 is provided with a second motor 16. The output end of the second motor 16 is provided with a second drill bit 17. The position of the bent rods 18 can be adjusted at the lower end of the second top plate 12.

[0026] In this embodiment, both the first lifting component 7 and the second lifting component 8 are cylinders, and the first motor 14, the second motor 16 and the drive motor 21 are servo motors.

[0027] Workpiece clamping: Place the front fork body 4 in the placement slot 3 of the base 2, and use the clamping slot 6 at the lower end of the clamping seat 5 to drive the lifting rod down in conjunction with the first lifting component 7 (using a cylinder) so that the clamping seat 5 presses the front fork body 4.

[0028] In this embodiment, the inner walls of both the clamping groove 6 and the placement groove 3 are provided with anti-slip textures.

[0029] The anti-slip texture on the inner walls of the clamping groove 6 and the placement groove 3 increases friction and ensures that the front fork body 4 is securely clamped.

[0030] Drilling operation: Activate the second lifting assembly 8 (also using a cylinder), its output end drives the frame 9 to descend, thereby causing the first top plate 11 and the second top plate 12 on the bottom support plate 10 of the frame 9 to descend. The first motor 14 (servo motor) at the lower end of the first top plate 11 drives the first drill bit 15 to rotate, and the second motor 16 (servo motor) connected to the lower end of the second top plate 12 through the bent rod 18 drives the second drill bit 17 to rotate, realizing synchronous drilling at multiple positions on the front fork body 4.

[0031] In this embodiment, the clamping seat 5 is fixed to the top of the lifting rod by screws, and the base 2 is fixed to the upper end of the processing table 1 by screws. The first top plate 11 and the second top plate 12 are both penetrated by the support plate 10 and are slidably connected to the support plate 10. The first top plate 11 and the second top plate 12 are provided with a plurality of locking rods 13. The bottom end of the locking rod 13 contacts the support plate 10, and the locking rod 13 is threadedly connected to the first top plate 11 and the second top plate 12.

[0032] In this embodiment, two sliding grooves 19 are symmetrically arranged on the second top plate 12. The top end of the bent rod 18 is provided with a slider that is slidably connected to the sliding groove 19. The upper end of the slider is provided with a movable seat 20. A drive motor 21 is provided on one side of the second top plate 12. The output end of the drive motor 21 is provided with a rotating shaft 22. Two threaded rods 23 with reverse thread structure are symmetrically arranged on the rotating shaft 22. The two threaded rods 23 pass through the two movable seats 20 respectively and are threadedly connected to the movable seats 20.

[0033] Position Adjustment: When it is necessary to adjust the position of the first top plate 11 and the second top plate 12 on the support plate 10, loosen the locking rod 13 to disengage it from the support plate 10. At this time, the first top plate 11 and the second top plate 12 can slide along the support plate 10 to a suitable position (a scale strip can be added to the support plate 10 to facilitate observation of the movement position of the first top plate 11 and the second top plate 12), and then tighten the locking rod 13 to fix it. For adjusting the position of the bent rod 18 at the lower end of the second top plate 12, start the drive motor 21 (servo motor). The rotating shaft 22 at its output end drives the threaded rod 23 with reverse thread structure at both ends to rotate. Through the action of the thread structure, the movable seat 20, which is threaded to the threaded rod 23, moves towards or in opposite directions along the sliding groove 19 on the second top plate 12 with the cooperation of the slider, thereby driving the bent rod 18 to the designated position.

[0034] To adapt to different workpieces: If different batches of front fork bodies 4 need to be processed, by disassembling the clamping seat 5 (fixed with screws) fixed to the top of the lifting rod and the base 2 (fixed with screws) on the upper end of the processing table 1, and replacing the base 2 and clamping seat 5 with the corresponding specifications, and at the same time adjusting the positions of the first top plate 11, the second top plate 12 and the bent rod 18, the clamping, fixing and drilling of front fork bodies 4 of different sizes can be achieved.

[0035] High-efficiency drilling: The first drill bit 15 and the second drill bit 17 can simultaneously drill holes in multiple positions on the front fork body. Compared with the traditional single drill bit drilling in sequence, the processing efficiency is greatly improved, and the drilling time of a single workpiece can be shortened by about 30%-50%.

[0036] High versatility: By replacing the base 2 and clamping seat 5, and adjusting the positions of the first top plate 11, the second top plate 12 and the bending rod 18, it can adapt to the processing needs of different batches and sizes of front fork bodies 4, reducing the idle time of the equipment and improving the scope of use and economic benefits of the equipment.

[0037] Increased automation: Compared to existing technologies that require frequent manual intervention to switch drilling positions, this device achieves most of the adjustment operations through motor drive, reducing manual operation steps. Especially in mass production, it significantly reduces time costs and improves the level of automation in production.
