Technical Field
[0001] This utility model belongs to the field of jig technology, specifically relating to a fixing mechanism for oiling a gear disc. Background Technology
[0002] A gear disc is a type of mechanical transmission component, typically used to transmit power and change the speed or direction of motion. A gear disc consists of a disc-shaped body and gears mounted around it for meshing with other gears or racks. A mounting hole is located in the center of the body for securing the gear disc to a shaft or other mechanical component.
[0003] Before assembling a gearbox, the gears need to be oiled. Oiling lubricates the gears and reduces friction: gears generate friction during operation, and oiling reduces this friction, decreases wear, and extends the gearbox's lifespan. Lubricating oil also reduces noise; well-lubricated gears run more smoothly and quietly. However, currently, the oiling process involves the worker holding the gearbox in one hand and an oil hose in the other, pressing the hose's outlet against the gears, rotating the gearbox, and simultaneously squeezing out lubricating oil to apply to the gears.
[0004] Workers will become fatigued from rotating the gear disk for a long time, which will reduce the rotation speed and decrease the stability of the gear disk when held, thus affecting the uniformity and efficiency of oiling. Summary of the Invention

[0032] This embodiment provides a fixing mechanism for oiling a gear disk, including an operating table 1. The operating table 1 is the base of this utility model and is used to support the entire fixing mechanism. The operating table 1 can be flat. A first upright plate 2 is provided on the upper surface of the operating table 1. The first upright plate 2 is also flat. Bolts are screwed from the bottom surface of the operating table 1 upwards into the bottom of the first upright plate 2 for connection and fixation. A motor 3 is fixed on the back of the first upright plate 2. Bolts are screwed from the front surface of the first upright plate 2 through the housing of the motor 3 for connection and fixation. The output shaft of the motor 3 passes through the first upright plate 2.
[0033] A mold head 4 is fixed on the output shaft of the motor 3. The mold head 4 is made of a metal block. The front end of the mold head 4 is provided with a first limiting block 40. The side surface contour of the first limiting block 40 matches the first through hole 50 in the middle of the gear disk 5. The shape of the first limiting block 40 is designed according to the first through hole 50 in the middle of the gear disk 5.
[0034] The front surface of the first limiting block 40 has a recessed first slot 400 that runs vertically through it; the first slot 400 is used to embed and fix the limiting strip 51 in the first through hole 50 on the gear disk 5, and the mold head 4 can drive the gear disk 5 to rotate; the limiting strip 51 on the gear disk 5 can be embedded in the first slot 400 to achieve fixed synchronous movement between the two.
[0035] If the first through hole 50 of the gear disk 5 is rectangular, the side surface contour of the first limiting block 40 can be changed to a rectangle.
[0036] A first threaded blind hole 401 is formed by a recess on the front surface of the first limiting block 40;
[0037] It also includes a clamping block 6, which is long and has a first rotating hole 60; the clamping block 6 is a metal strip or a plastic strip.

[0039] The clamping block 6 spans the limiting strip 51 and can block the gear disk 5. The misalignment of the clamping block 6 fixes the gear disk 5 in place so that it will not fall out;
[0040] As described above, in the specific usage process, the motor 3 is fixed on the first upright plate 2, and the mold head 4 is fixed on the output shaft of the motor 3. The first light-transmitting hole on the gear disk 5 to be oiled is aligned with the first limiting block 40 and inserted. At the same time, the limiting strip 51 on the gear disk 5 is inserted into the first slot 400 to achieve initial fixation. Then, the fixing bolt 7 is inserted into the clamping block 6 and screwed into the first blind hole. The clamping block 6 rotates and crosses the limiting strip 51. The fixing bolt 7 is tightened to clamp and fix the clamping block 6 and the first limiting block 40. The motor 3 starts to rotate, and the mold head 4 drives the gear disk 5 to rotate slowly and uniformly to apply lubricating oil.
[0041] After the oiling is complete, turn off motor 3, reverse the fixing bolt 7, rotate the clamp 6 to remove it, and then remove the gear disk 5.
[0042] In another embodiment, the length of the clamping block 6 is designed to be smaller than the size of the first through hole 50, so that the gear disk 5 can be removed without removing the clamping block 6, by rotating the clamping block 6 to a position inside the first through hole 50. This is more convenient.
