Description of reference numerals: the oil filling device comprises a handle 1, a screw rod 2, a piston 3, an oil cylinder 4, a threaded hole 4-1, an oil filling port 4-2, a positioning sleeve 5, an oil outlet 5-1, a supporting seat 6, an O-shaped sealing ring 7, a sealing ring 8, an inner ring 8-1 and oil 9.
Detailed Description
The invention will be described in detail below with reference to the following drawings:
example (b): as shown in the attached drawing 2, the sealing ring grease smearing tool comprises a handle 1, a screw rod 2, a piston 3, a grease cylinder 4, a positioning sleeve 5 and a sealing ring 8, wherein a threaded hole 4-1 is formed in one end of the grease cylinder 4, and an oil filling port 4-2 is formed in the other end of the grease cylinder 4 and used for filling grease 9 into an inner cavity of the grease cylinder 4. The screw rod 2 is movably connected to the grease cylinder 4 through a threaded hole 4-1, a handle 1 is arranged at one end, extending out of the grease cylinder 4, of the screw rod 2, and a piston 3 is fixedly arranged at one end, extending into the grease cylinder 4, of the screw rod 2. An O-shaped sealing ring 7 is installed on the periphery of the piston 3, and the piston 3 and the inner wall of the grease cylinder 4 are sealed through the O-shaped sealing ring 7. The handle 1 is rotated to drive the screw rod 2 to rotate, so that the piston 3 slides along the inner wall of the grease barrel 4. The positioning sleeve 5 is detachably mounted on the oil injection port 4-2, twenty rows (more in the embodiment) of oil outlets 5-1 are uniformly distributed along the circumference of the positioning sleeve 5, one sealing ring 8 is correspondingly sleeved on each row of oil holes 5-1, and the piston 3 extrudes grease 9 to be discharged from the oil outlets 5-1 to the inner cavity of the sealing ring 8, so that smearing is realized. Preferably, the bottom of the grease cylinder 4 is provided with a supporting seat 6 for supporting the grease cylinder 4.
With reference to fig. 2, the smearing process using the smearing tool comprises the following steps:
1) rotating the handle 1, retracting the piston 3 to the leftmost end (namely, the end close to the threaded hole 4-1), taking down the positioning sleeve 5, filling the grease 9 into the inner cavity of the grease cylinder 4 through the grease inlet 4-2, and then mounting the positioning sleeve 5;
2) sealing rings 8 to be coated are sleeved on the oil outlet holes 5-1 of the positioning sleeve 5 in a one-to-one correspondence manner, and twenty sealing rings 8 are correspondingly sleeved on the twenty-row oil outlet holes 5-1;
3) the handle 1 is rotated to enable the piston 3 to gradually move rightwards (close to one end of the oil filling port 4-2), the grease 9 in the grease cylinder 4 is extruded by the piston 3, enters the positioning sleeve 5 along the oil filling port 4-2 and is discharged into each sealing ring 8 through the oil outlet 5-1; because the handle 1 is in threaded connection with the grease cylinder 4 by the screw rod 2, the control on the amount of grease injected into the sealing ring 8 can be realized by controlling the number of turns of rotation of the handle 1 (namely the movement stroke of the piston 3); after calculation, the handle 1 needs to be rotated for a half circle when the sealing ring 8 is completely coated once;
4) after the smearing is finished, the sealing rings 8 are sequentially taken down.
Compared with the prior art, when the sealing ring is smeared with grease, the sealing ring is more uniform and full, and the product quality is effectively improved. Compared with the prior art that only 5-8 sealing rings can be coated at one time, the invention can coat at least twenty sealing rings at one time, and the production efficiency is greatly improved. And when in smearing, the handle is only required to be rotated, repeated smearing is not required, the single operation time is shortened, and the production beat is shortened.
It should be understood that equivalent substitutions and changes to the technical solution and the inventive concept of the present invention should be made by those skilled in the art to the protection scope of the appended claims.
