Description

Technical Field

[0001] This utility model relates to the field of flywheel processing technology, specifically a detachable internal combustion engine flywheel hole fixture. Background Technology

[0002] The flywheel is a crucial component of an internal combustion engine. Its primary function is to utilize its rotational inertia to balance power output fluctuations throughout the engine's various operating cycles, ensuring smooth engine operation. In the four strokes of a four-stroke internal combustion engine—intake, compression, power, and exhaust—only the energy generated by fuel combustion is directly converted into mechanical energy during the power stroke. The energy generated in the other three strokes relies on the flywheel's inertia. Therefore, the flywheel continuously converts between storing and releasing energy, enabling the engine to operate consistently and stably. Furthermore, the flywheel also serves as a mounting point for accessories such as starter motors and pulleys.

[0003] Authorization announcement number CN212552775U discloses a drilling fixture for positioning holes in a flywheel housing. The technical solution is as follows: "It includes a base and a worktable disposed above the base. A support seat is provided at the center of the upper surface of the worktable. A positioning post is detachably installed on the upper part of the support seat. Clamping devices for clamping the flywheel housing are provided on both the left and right sides of the support seat." The beneficial effects are: it achieves positioning and clamping of the flywheel housing, is easy to operate, and includes a compression spring and protective pad to protect the flywheel housing and prevent damage.

[0004] The above technical solution has the following defects: it lacks a replacement structure for the clamping block, the clamping block can only be used for flywheels of a compatible size, and it cannot effectively clamp and fix flywheels of different sizes. At the same time, it is difficult to disassemble and replace the clamping block, resulting in a limited range of applications. Therefore, a detachable internal combustion engine flywheel hole clamp is proposed to solve the problems mentioned above. Utility Model Content

Limit adjustment seats 5 are fixedly installed on the top of the two movable shafts of the straight-line module slide 4 with forward and reverse teeth. A sliding groove is opened inside the support plate 3. The two movable shafts of the straight-line module slide 4 with forward and reverse teeth are slidably connected inside the sliding groove. The limit adjustment seats 5 are slidably connected to the top of the support plate 3.

[0030] It should be noted that this allows for adjustment of the distance between the two limit adjustment seats 5, thereby enabling the installation of clamps of different sizes.

[0031] In this embodiment, an electric push rod 6 is fixedly installed on the top of the support plate 3, and a limit adjustment seat 5 is slidably connected to the top of the workbench 16. The telescopic shafts of the two electric push rods 6 are movably connected to the outer wall of the opposite side of the two limit adjustment seats 5, and a clamping seat 7 is slidably connected between the two adjacent limit adjustment seats 5. A protective pad 8 is fixedly installed on the side of the clamping seat 7 near the workbench 16.

[0032] It should be noted that the limit adjustment seat 5 limits the clamping seat 7 to ensure that the clamping seat 7 can move and adjust in a horizontal straight line.

[0033] In this embodiment, two limit adjustment seats 5 are provided with limit grooves on opposite sides, and clamping seats 7 are slidably connected inside the limit grooves. An arc-shaped groove is provided on the side of clamping seats 7 near the worktable 16. A protective pad 8 is installed inside the arc-shaped groove. The protective pad 8 is arc-shaped.

[0039] The working principle of the above embodiments is as follows:

[0040] When installing the clamping seat 7, place the clamping seat 7 between two adjacent limit adjustment seats 5, then start the forward and reverse thread linear module slide 4 to drive the two limit adjustment seats 5 to move closer to the clamping seat 7 and limit them. Then move the top plate 11 from top to bottom, so that the limit rod 13 moves into the inside of the limit card seat 9. At this time, the top plate 11 is attached to the top of the support seat 10. Finally, the fastening screw 12 passes through the internal thread of the top plate 11 and connects to the inside of the support seat 10, thus completing the installation of the clamping seat 7. Then start the electric push rod 6 to push the clamping seat 7 to move and clamp and fix the flywheel.
