Description

Technical Field

[0001] The utility model relates to the technical field of flywheel processing, and more specifically, to a flywheel surface grooving device. Background Art

[0002] The flywheel has a large moment of inertia. Since the work done by each cylinder of the engine is discontinuous, the engine speed is also variable. When the engine speed increases, the kinetic energy of the flywheel increases and the energy is stored; when the engine speed decreases, the kinetic energy of the flywheel decreases and the energy is released. Therefore, the flywheel can be used to reduce the speed fluctuation during the operation of the engine.

[0003] The signal wheel is an important component of the flywheel. A mounting groove needs to be processed on the upper end of the signal wheel, and the signal wheel is installed on the annular protrusion set on the dual-mass flywheel through the mounting groove to limit the signal wheel. At present, there is no reliable positioning tooling design for the center and angle positioning of the signal wheel parts.

[0004] After searching, the Chinese patent with authorization announcement number CN221184793U discloses a flywheel surface grooving device. The structure drives the slider to move toward or away along the slide groove through a bidirectional threaded rod, and makes the limit column move toward or away. The limit column is inserted into the limit mounting hole to position the center of the signal wheel, and the signal wheel is positioned at an angle by inserting the abutment block in the limit groove. The rotating disk is driven to rotate by a motor and cooperates with the drill bit of the drilling rig to perform the groove processing operation.

[0005] However, when this structure is actually used, during the positioning of the signal wheel, it is necessary to insert the two limit posts into the two mounting holes on the signal wheel for positioning operation. However, during the operation, it is difficult for the operator to control whether the distances between the two limit posts and the two mounting holes on the signal wheel are the same, and it takes a lot of time to adjust the distance between the two limit posts, which affects the processing progress. In view of this, the utility model proposes a flywheel surface grooving device. Utility Model Content

[0022] Specifically, in this structure, the signal wheel 8 can be installed on the surface of the support disk 7 through the mounting hole 9. When it is necessary to make a circular groove on the signal wheel 8 on the flywheel, the electric push rod 3 can drive the movable plate 4 to move downward, and the movable plate 4 drives the drill bit 6 to extend to the surface of the signal wheel 8. At this time, the first motor 5 drives the drill bit 6 to rotate. When the support disk 7 rotates, the signal wheel 8 can be rotated, and then the drill bit 6 is used to make a circular groove on the surface of the signal wheel 8.

[0023] In a specific embodiment, as shown in the attached Figure 3 , 4 As shown in , 5, the adjustment and positioning structure includes a bidirectional threaded screw 10, a mounting groove 11 is opened on the surface of the support plate 7, the bidirectional threaded screw 10 is rotatably installed in the inside of the mounting groove 11, and an adjustment block 12 is arranged at one end of the bidirectional threaded screw 10, and two movable blocks 13 are arranged on the outside of the bidirectional threaded screw 10, a positioning screw 14 is arranged on the top of the movable block 13, and a locking screw head 15 is arranged on the top of the positioning screw 14, the positioning screw 14 is adapted to the mounting hole 9 structure on the surface of the signal wheel 8, the locking screw head 15 is threadedly connected with the positioning screw 14, a measuring ruler 16 is embedded and installed on one side of the mounting groove 11 on the surface of the processing table 1, an indicator mark 17 is installed on the surface of the movable block 13 by a screw, the adjustment block 12 is connected to one end of the bidirectional threaded screw 10, the two movable blocks 13 are both threadedly connected on the outside of the bidirectional threaded screw 10, and the indicator mark 17 is slidably connected to the surface of the measuring ruler 16.

[0026] When the positions of the two positioning screws 14 are consistent with the positions of the two mounting holes 9 on the signal wheel 8, the positioning screws 14 are passed through the mounting holes 9 on the signal wheel 8, and the signal wheel 8 is fastened by tightening the locking screw head 15 and the positioning screw 14 threads to avoid shaking and deflection of the signal wheel 8 during the slotting process, which affects the slotting accuracy.

[0027] In a specific embodiment, as shown in the attached Figure 1 , 2 As shown, the surface of the processing table 1 is located at the bottom of the supporting disk 7 and a connecting disk 18 is fixedly provided.

[0030] When the above structure is used, the operator uses a measuring tool to measure the distance between the two mounting holes 9 on the surface of the signal wheel 8 in advance. At the same time, the bidirectional threaded screw 10 is driven to rotate inside the mounting groove 11 through the adjusting block 12. The rotation of the bidirectional threaded screw 10 drives the two external threaded movable blocks 13 to move closer to and away from each other, so as to adjust the distance between the two positioning screws 14 so that the distance between the two positioning screws 14 is the same as the distance between the two mounting holes 9 on the surface of the signal wheel 8.

[0031] When the two movable blocks 13 adjust the distance between the two positioning screws 14, they can drive the indicator mark 17 to move in contact with the surface of the measuring ruler 16. According to the sliding value of the indicator mark 17 on the surface of the measuring ruler 16, the distance between the two positioning screws 14 can be calculated, and then according to the distance between the two mounting holes 9 on the signal wheel 8 measured in advance, the distance between the two positioning screws 14 can be made consistent with the distance between the two mounting holes 9 on the signal wheel 8.

[0032] When the positions of the two positioning screws 14 are consistent with the positions of the two mounting holes 9 on the signal wheel 8, the positioning screws 14 are passed through the mounting holes 9 on the signal wheel 8, and the signal wheel 8 is fastened by tightening the locking screw head 15 with the positioning screw 14 to prevent the signal wheel 8 from shaking and deviating during the slotting process, thereby affecting the slotting accuracy;

[0033] The electric push rod 3 is used to drive the moving plate 4 to move downward, and the moving plate 4 drives the drill bit 6 to extend to the surface of the signal wheel 8. At this time, the first motor 5 drives the drill bit 6 to rotate. At the same time, the second motor 22 drives the main gear 21 to rotate, and the main gear 21 drives the slave gear 20 to rotate, so that the slave gear 20 drives the shaft rod 19 to rotate, so that the bottom end of the shaft rod 19 rotates on the surface of the connecting plate 18, and the top end of the shaft rod 19 drives the support plate 7 to rotate, and the support plate 7 drives the signal wheel 8 on the surface to rotate, and then cooperates with the rotating drill bit 6 to groove the surface of the signal wheel 8;

[0034] After the slotting is completed, the mounting hole 9 on the signal wheel 8 can be separated from the positioning screw 14 by twisting the locking screw head 15.
