Technical Field

[0001] The utility model belongs to the flywheel eccentric slot hole Processing The technical field relates in particular to a flywheel eccentric slot processing device. Background Art

[0002] A flywheel is a disc-shaped part with a large moment of inertia. Its main function is to store energy and inertia outside the power stroke of the engine. Of course, the definition of a flywheel is broad. Some wheel-shaped accessories of vehicles such as bicycles are also called flywheels, but they have the same point, that is, they all have a number of through holes. In the processing of flywheels, the slots are generally formed by stamping or drilling and milling, so machine tool drilling tools or stamping equipment are required for processing.

[0003] In the existing flywheel slot hole processing, a positioning hole is first opened in the flywheel before drilling, and then the drill is used to drill to avoid the instability of the drill bit during drilling. However, the flywheel needs to be reinstalled and positioned for drilling after the positioning hole is processed. This processing method is not only inefficient, but also prone to inaccurate positioning due to multiple processing, which causes the drill bit to be unable to align with the positioning hole, thereby affecting the quality of the hole processing.

[0004] Therefore, we propose a flywheel eccentric slot processing device to solve the above problems. Utility Model Content

The flywheel is placed on the placement table 14, and then the T-type stage 7 is driven to move, so that the placement table 14 on the T-type stage 7 is fixed. Then, when the flywheel moves to the bottom of the positioning drill 10 with the moving component, it stops and the positioning hole is processed. Then, the moving component continues to move the placement table 14 to the bottom of the drill bit 11 for hole processing, thereby reducing repeated installation of the flywheel and improving the accuracy of drilling, thereby improving processing efficiency.

[0023] Reference Figure 3-Figure 4 The driving assembly includes a pinion 20 and two racks 16. The two racks 16 are located on both sides of the placement table 14, with the gear teeth facing inward. The two racks 16 are respectively fixedly connected to the vertical ends of the L-shaped clamping plate 15. The pinion 20 is arranged between the T-shaped table 7 and the placement table 14, and the pinion 20 is meshed with the racks 16 on both sides.

[0027] Working principle:

[0028] First, place the flywheel on the placement table 14, and then drive the lead screw 6 to rotate as the motor 4 drives, and the rotation of the lead screw 6 drives the T-type table 7 to move along the moving groove 5. When the T-type table 7 moves, the large gear 19 in the T-type table 7 is meshed with the tooth plate 9, and then the meshing of the tooth plate 9 and the large gear 19 causes the connecting shaft 18 and the small gear 20 on the top of the connecting shaft 18 to rotate, and the rotation of the small gear 20 causes the racks 16 on both sides of the small gear 20 to shrink, and the flywheel on the placement table 14 is fixed. Moreover, after the L-shaped clamping plate 15 fixes the flywheel, since the T-type table 7 is still moving, the T-block 12 on one side of the tooth plate 9 slides along the sliding plate 8 to keep the flywheel fixed, and stops below the positioning drill 10 as it moves, and then the moving assembly continues to move the placement table 14 to below the drill bit 11 for hole processing, thereby reducing repeated installation of the flywheel.
