[0028] like Figure 1-7 As shown, this utility model provides a drilling mechanism for processing flywheel side holes, including a worktable 1, a limiting component 5 and a processing component 6. The top of the worktable 1 is rotatably connected to a fixed plate 3 via a rotating column 2. The center of the fixed plate 3 is provided with a positioning rod 31 that is inserted into the center hole 71 of the flywheel 7. A right-angle reduction motor 4 is installed at the bottom of the worktable 1, and the output shaft of the right-angle reduction motor 4 is connected to the rotating column 2.

[0029] In addition, the limiting component 5 is provided on the fixed plate 3 and is used to fix the flywheel 7. The limiting component 5 includes a cylinder 51 and a pressure plate 52. The cylinder 51 is installed at the bottom of the fixed plate 3 and its piston rod is connected to the support plate 522 on the side of the pressure plate 52. The pressure plate 52 cooperates with the protrusion 72 on the side of the flywheel 7. Upper positioning plates 53 are slidably connected in the sliding grooves on both sides of the pressure plate 52. Each upper positioning plate 53 has a guide rod 531 slidably inserted into the guide groove 521 on the side of the pressure plate 52. The two guide rods 531 are connected by a grip 55. The upper positioning plates 53 on both sides can be moved simultaneously by the grip 55.

[0030] In addition, the guide rod 531 is provided with a baffle 532 on the outside of the guide groove 521. Each upper positioning plate 53 is slidably connected to the slide groove 2. The lower end of the lower positioning plate 54 is provided with a rubber pad 541 to avoid damage to the flywheel 7 when the lower positioning plate 54 contacts the flywheel 7. The side of the lower positioning plate 54 is provided with a guide rod 542 that is slidably inserted into the guide groove 533 on the side of the upper positioning plate 53.

[0031] However, the processing component 6 is set on the workbench 1 and is used to process the side hole of the flywheel 7. The processing component 6 includes an electric push rod 61, a drilling motor 65 and a drill bit 66. The bracket 62 includes a fixed column 621 and a side plate 622. The fixed column 621 is set on the workbench 1 and the side plate 622 is vertically set on the fixed column 621.

[0032] It is worth noting that the electric push rod 61 is mounted on the side plate 622, and the drive end of the electric push rod 61 is provided with a lifting plate 64 that is slidably connected to the slide rod 63 on the worktable 1. The drilling motor 65 is mounted on the lifting plate 64 and its output shaft is provided with a drill bit 66. The drill bit 66 is used to process the protrusion 72 on the flywheel 7.

[0033] Detailed implementation methods and principles:

[0034] S1. Pre-positioning: When processing the flywheel 7, pull the gripping rod 55 on the pressure plate 52 upward to move the upper positioning plate 53 and the lower positioning plate 54 upward, so that the flywheel 7 can be sleeved on the positioning rod 31 on the fixed plate 3 through the center hole 71 on it.

[0035] S2. Roughly adjust the position: Continuously adjust the position of the flywheel 7 on the positioning rod 31 so that the protrusion 72 on the flywheel 7 is roughly below the two lower positioning plates 54;

[0036] S3. Precisely adjust the position: Slowly adjust the position of the flywheel 7 and gradually move the grip 55 down so that the protrusion 72 on the flywheel 7 is between the two lower positioning plates 54;

[0037] S4. Fixing: The piston rod of the control cylinder 51 retracts, causing the pressure plate 52 to move downward, so that the lower positioning plate 54 and the upper positioning plate 53 retract into the pressure plate 52, and finally the flywheel 7 is pressed and fixed by the pressure plate 52.

[0038] S5. Machining: Turn on the drilling motor 65. The output shaft of the drilling motor 65 drives the drill bit 66 to rotate and controls the drive end of the electric push rod 61 to drive the lifting plate 64 to move down along the slide rod 63. The rotating drill bit 66 drills holes in the protrusion 72 of the flywheel 7.

[0039] S6. Next processing: When the drilling is completed, control the drive end of the electric push rod 61 to move the lifting plate 64 up along the slide rod 63. Then control the output shaft of the right angle reduction motor 4 to rotate the rotating column 2 by a corresponding angle, so that the protrusion 72 of the flywheel 7 is located below the drill bit 66 for the next drilling. Then proceed with the operation of step S5.
