Description

Technical Field

[0001] This utility model relates to the field of flywheel processing and manufacturing equipment technology, and in particular to a positioning device for flywheel manufacturing. Background Technology

[0002] A flywheel is a disc-shaped component with a large moment of inertia. It functions like an energy storage device. During the use of a flywheel, it is often necessary to test its quality and performance to ensure that its key characteristics meet the requirements.

[0003] Existing Chinese patent CN211565616U discloses a flywheel positioning fixture that can position a flywheel vertically, exposing most of it for easy monitoring of key performance parameters. The fixture is versatile and can be used to position flywheels of various diameters and thicknesses. The positioning portion of the flywheel includes at least the rim of the gear section. By driving the flywheel body to rotate along the contact surface between the outer surface of the gear rim and the arc-shaped limiting surface of the limiting groove, the flywheel can be rotated as needed, avoiding the hassle of repeated hoisting for adjusting the flywheel position and improving work efficiency. The positioning blocks on the fixture can move up and down (vertically) and left and right (horizontally) to adjust the positioning position, facilitating the positioning of flywheels of various thicknesses and sizes.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following problems exist: When the above-mentioned device clamps flywheels of different diameters, since the limiting groove is fixed, the contact angle between the wheel rim and the limiting groove is different. The limiting groove cannot be changed according to the size of the flywheel, which affects the positioning effect. Utility Model Content

[0021] This application discloses a positioning device for flywheel manufacturing. (Refer to...) Figure 1 , Figure 2 and Figure 3 The positioning device for flywheel manufacturing includes a base plate 1, a fixed frame 2 connected to the base plate 1, a rotary motor 21 connected to the fixed frame 2, a rotating block 22 connected to the output shaft of the rotary motor 21, a clamping component 3 for clamping the flywheel and which is detachable and replaceable provided on the rotating block 22, a mounting frame 4 slidably provided on the base plate 1, and a mounting frame 4 symmetrically provided on both sides of the fixed frame 2, a driving component 5 for driving the two mounting frames 4 to move relative to each other provided on the base plate 1, a clamping roller 6 rotatably connected to the mounting frame 4, the axis of the clamping roller 6 being parallel to the axis of the output shaft of the rotary motor 21, one clamping roller 6 symmetrically provided at each end of the mounting frame 4, the axis of symmetry of the two clamping rollers 6 being in the same horizontal plane as the output shaft of the rotary motor 21, and the roller surface of the clamping roller 6 being able to abut against the surface of the flywheel.

[0022] The clamping assembly 3 includes a threaded sleeve 31, a connecting flange 32, and a locking bolt 33. The diameter of the threaded sleeve 31 is adapted to the inner diameter of the flywheel shaft hole. The connecting flange 32 is fixedly connected to one end of the threaded sleeve 31. The axis of the connecting flange 32 is collinear with the axis of the threaded sleeve 31. The rotating block 22 has a groove for connecting the connecting flange 32. The locking bolt 33 is connected inside the threaded sleeve 31. The end of the locking bolt 33 can be pressed against the surface of the flywheel.

[0023] When clamping the flywheel, select a suitable threaded sleeve 31 according to the diameter of the flywheel shaft hole. The threaded sleeve 31 is connected to the rotating block 22 by bolts and connecting flange 32. Then, the flywheel is sleeved on the outside of the threaded sleeve 31, and the locking bolt 33 is connected to the threaded sleeve 31 to press and fix the flywheel.

[0024] The threaded sleeve 31 is provided with a chamfer, which is located at the end of the threaded sleeve 31 away from the connecting flange 32. With this arrangement, the flywheel does not need to be completely aligned with the threaded sleeve 31 when it is inserted, which makes it easier for the flywheel to be fitted on the outside of the threaded sleeve 31.

[0025] The depth of the groove is greater than the thickness of the connecting flange 32. This design allows the flywheel to fit completely against the turntable, increasing the contact area and improving the clamping effect on the flywheel.

[0026] The drive assembly 5 includes a fixed block 51, a fixed bearing 52, a bidirectional threaded rod 53, a nut seat 54, a connecting plate 55, and a drive motor 56. The fixed block 51 is connected to the base plate 1. The axis of the fixed block 51 in the length direction is perpendicular to the output shaft of the rotating motor 21. The fixed block 51 has an installation groove along its length. The fixed bearing 52 is connected to the fixed block 51. There is one fixed bearing 52 at each end of the installation groove. The bidirectional threaded rod 53 is connected between the two fixed bearings 52. The drive motor 56 is connected to the base plate 1. The output shaft of the drive motor 56 is coaxially connected to one end of the bidirectional threaded rod 53 that passes through the fixed bearing 52 via a coupling. The nut seat 54 is connected to the bidirectional threaded rod 53. The nut seat 54 is cubic in shape. The side wall of the nut seat 54 slides against the inner wall of the installation groove. The connecting plate 55 is connected to the nut seat 54. The connecting plate 55 is L-shaped. The mounting bracket 4 is connected to the connecting plate 55.

[0027] During operation, the bidirectional threaded rod 53 is driven to rotate by the drive motor 56. Since the nut seat 54 is confined in the mounting groove, it can move along the length direction of the bidirectional threaded rod 53 to adjust the distance between the two mounting brackets 4.

[0028] The mounting frame 4 has a groove, and the clamping roller 6 is located between two opposite side walls of the groove. A connecting bearing 61 is connected to the roller shaft of the clamping roller 6. There is one connecting bearing 61 at each end of the roller shaft of the clamping roller 6. The connecting bearing 61 is connected to the mounting frame 4. This arrangement enables the clamping roller 6 to be rotatably connected to the mounting frame 4.

[0029] The implementation principle of the positioning device for flywheel manufacturing in this embodiment is as follows: During positioning, a suitable threaded sleeve 31 is first selected according to the diameter of the flywheel shaft hole. The threaded sleeve 31 is connected to the rotating block 22 by bolts and connecting flange 32. Then, the flywheel is sleeved on the outside of the threaded sleeve 31, and the locking bolt 33 is connected to the threaded sleeve 31 to press and fix the flywheel. Then, the drive motor 56 drives the bidirectional threaded rod 53 to rotate. Since the nut seat 54 is restricted in the mounting groove, it can move along the length direction of the bidirectional threaded rod 53, so that the two mounting brackets 4 move closer to each other, and the four clamping rollers 6 clamp and fix the two sides of the flywheel, thereby achieving the function of making the positioning device applicable to flywheels of different sizes and ensuring its positioning effect.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
