[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figure 1-5 This utility model relates to a drilling device for processing automotive parts, comprising a mounting base 1, a worktable 2, a mounting plate 3, a lifting mechanism, and a drilling mechanism. The worktable 2 is rotatably mounted on the mounting base 1, and has multiple evenly spaced slots 26 and through holes 4, with the slots 26 communicating with the through holes 4. The lifting mechanism and the mounting plate 3 are both mounted on the mounting base 1, and the drilling mechanism is mounted on the mounting plate 3. A self-driving mechanism is provided between the lifting mechanism and the worktable 2, and the self-driving mechanism includes an inner rotating wheel 5 and an outer gear 6. The transmission gear 7, wherein the inner rotating wheel 5 is fixedly mounted on the screw 13 in the lifting mechanism, and the outer gear 6 is rotatably mounted on the screw 13 in the lifting mechanism. The inner rotating wheel 5 has an outer groove 8, and a pawl 9 is hinged in the outer groove 8. A torsion spring is provided at the hinge point between the pawl 9 and the outer groove 8. The outer gear 6 has evenly spaced ratchet grooves 10 inside, and the pawl 9 and ratchet grooves 10 cooperate with each other. The transmission gear 7 is rotatably mounted on the mounting base 1, and the worktable 2 has evenly spaced tooth grooves 11. The outer gear 6 meshes with the tooth grooves 11 through the transmission gear 7.

[0023] This design allows for convenient operation. During use, the disc-shaped automotive parts are placed inside the storage slot 26. A lifting mechanism lowers the mounting plate 3 to a suitable position, allowing the drilling mechanism on the mounting plate 3 to first position the disc-shaped automotive parts before drilling them. As the screw 13 rotates within the lifting mechanism, it drives the inner rotating wheel 5. The pawl 9 on the inner rotating wheel 5 drives the outer gear 6 via the ratchet groove 10. The outer gear 6, through the transmission gear 7, drives the gear groove 11 on the worktable 2, thus driving the worktable 2. Conversely, when the screw 13 drives the inner rotating wheel 5 in the opposite direction, the pawl 9, compressed by the ratchet groove 10, no longer drives the outer gear 6. Therefore, when the screw 13 rotates in the forward direction, the storage slot 26 on the worktable 2 is positioned below the drilling mechanism, while when the screw 13 rotates in the reverse direction, it no longer drives the worktable 2. This automatic switching of the storage slot 26 on the worktable 2 is quite convenient.

[0024] The lifting mechanism includes a lifting motor 12 and a screw 13. The lifting motor 12 is fixedly mounted on the mounting base 1 and provides power to the screw 13. The screw 13 is rotatably mounted on the mounting base 1.

[0025] The mounting base 1 has a slide groove 14, the screw 13 is located in the slide groove 14, and a baffle 15 is fixedly installed in the slide groove 14. The baffle 15 has a rod hole for the screw 13 to pass through.

[0026] A slider 16 is connected to the mounting plate 3. The slider 16 is slidably engaged with the slide groove 14, and the slider 16 is provided with a screw hole that engages with the screw 13.

[0027] With this design, the lifting motor 12 drives the screw 13 to move, and the screw 13 drives the slider 16 on the mounting plate 3 to slide in the slide groove 14 through the thread, thereby realizing the vertical driving process of the mounting plate 3; the baffle 15 can block the debris and prevent it from affecting the transmission of the self-driving mechanism.

[0028] Specifically, the drilling mechanism includes a drilling assembly, which includes an electric push rod 17, a motor frame 18, a drilling motor 19, and a drilling rod 20. The electric push rod 17 is fixedly mounted on the mounting plate 3, the motor frame 18 is fixedly mounted on the output end of the electric push rod 17, the drilling motor 19 is fixedly mounted on the motor frame 18, and the drilling rod 20 is fixedly mounted on the output shaft of the drilling motor 19.

[0029] This design allows the electric push rod 17 to drive the motor frame 18 to move vertically, and the drilling motor 19 to drive the drilling rod 20 to rotate, so as to facilitate drilling operations through the drilling rod 20, which can move vertically.

[0030] Specifically, the drilling mechanism also includes a positioning assembly, which includes two guide rods 21, two guide springs 22, a positioning cylinder 23, multiple telescopic rods 24, and a positioning ring 25. The two guide rods 21 are slidably engaged with two rod holes on the mounting plate 3, and the two guide springs 22 are respectively wrapped around the two guide rods 21. Both guide rods 21 are fixedly set with the positioning cylinder 23. The positioning cylinder 23 is fixed with the positioning ring 25 through multiple telescopic rods 24, and the positioning cylinder 23 has a circular hole for the drilling rod 20 to pass through.

[0031] With this design, when the mounting plate 3 moves, the guide spring 22 and the telescopic rod 24 will cause the positioning ring 25 to first contact the disc-shaped automotive part to be processed to achieve positioning. Then, the positioning cylinder 23 will abut against the worktable 2 and cover the outside of the drilling area to prevent debris from splashing.
