Oiling device

[0017] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present invention, the present invention will be further explained below in conjunction with specific drawings.

[0018] Such as figure 1 As shown, the oil applicator includes a transmission shaft 200, a connecting flange 100, an outer cover 400 flange-connected to the connecting flange 100, and a lower cover plate 500 at the lower end of the outer cover 400. An oil blocking mechanism 410 is provided on the outer cover 400.

[0019] Such as figure 2 As shown, the transmission shaft 200 is mounted on the sleeve of the connecting flange 100 through a bearing, and its lower end is connected to a sleeve 300. A number of through holes 310 are provided on the wall of the sleeve 300. The outer wall of the sleeve 300 and the outer cover 400 An oil cavity 600 is formed between the inner walls of the, and the oil cavity 600 communicates with the inside of the sleeve 300 through the through hole 310 so that the oil in the oil cavity 600 enters the inside of the sleeve 300 and is smeared on the thread of the bolt and nut. The oil blocking mechanism 410 extends into the oil cavity 600, close to the outer wall of the sleeve 300, and is used to increase the resistance to oil when the sleeve 300 rotates and increase the oil pressure on the outer surface of the sleeve 300 so that the oil can pass through the through hole more easily 310, smear on the thread of the bolt and nut. An oil seal 510 is provided at the joint between the lower end of the sleeve 300 and the lower cover plate 500 to achieve a good seal of the oil cavity 600 and prevent oil leakage. An oil injection hole 420 is provided on the outer cover to inject oil into the oil cavity. The oil injection hole 420 can also be provided on the lower cover plate 500 or the connecting flange 100

[0020] Such as image 3 As shown, the oil baffle mechanism 410 is composed of at least one oil baffle 410a, and the oil baffle 410a is made of metal or other materials with certain hardness. One end of the oil baffle plate 410a is embedded in the outer cover 400, and the other end extends into the oil cavity 600, close to the sleeve 300, and there is a gap between the oil baffle plate 410a and the outer wall of the sleeve 300. Friction, it is necessary to ensure a good oil blocking effect, so that when the sleeve 300 rotates, the oil can pass through the through hole 310 and be smeared on the thread of the bolt and nut. The side of the oil baffle plate 410a close to the sleeve 300 can be either a smooth structure or a convex-concave structure, or a brush structure, where the best oil pressure effect on the outer surface of the sleeve 300 is better.

[0021] Under oiling conditions, align the sleeve 300 of the oiler with the bolts and nuts that require oiling maintenance and press down, so that the sleeve 300 engages with the nuts of the bolts and nuts, and the oil injection pump injects a certain amount of oil into the oil cavity 600, the power system drives the sleeve 300 to rotate through the drive shaft 200. During the tightening process, the sleeve 300 rotates, and the oil in the oil cavity 600 follows the sleeve 300. When encountering the oil baffle 410a, the oil pressure increases and the oil penetrates The through hole 310 is applied to the exposed thread, and the nut passes through the thread of the bolt that has been oiled, and the oil is also applied to the thread of the nut, thereby achieving a better oiling effect. Through this device, it is possible to synchronize the oiling work during the tightening or loosening of the bolts and nuts. Compared with the manual oiling at the current stage, there is no need to completely remove the bolts and nuts, which saves work time and greatly reduces personnel input. The physical consumption of the staff is reduced, and the device can well control the oil output each time, and the oil is evenly coated, which reduces the waste of oil and reduces the cost.
