[0002] In the manufacturing process of self-lubricating bearings, the embedding of solid lubricant is a key step. After drilling holes in the copper-based bushing to create blind holes, the solid lubricant is embedded into the blind holes. Currently, the embedding of solid lubricant into blind holes is mostly done manually. Workers put the solid lubricant into a mixing basin, pour in lubricating oil and mix well. While rotating the oilless bushing, they use tweezers to pick up the solid lubricant one by one and embed it into each blind hole. Since there are many blind holes on the oilless bushing, the embedding operation needs to be repeated many times to embed multiple solid lubricants into the corresponding blind holes.

[0003] However, in the existing technology, when workers repeatedly perform the inlaying operation, the repeated use of tweezers to pick up solid lubricant can easily cause hand tension, cramps, and arm pain, resulting in a heavy workload for workers and slow inlaying efficiency of solid lubricant.

[0021] The receiving plate 6 is connected in the storage frame 3, the discharge port 7 corresponding to the receiving plate 6 and the guide hole 8 corresponding to the discharge port 7 are opened on the storage frame 3, the push rod 9 movably connected with the guide hole 8 is arranged on the storage frame 3, the storage frame 3 is cuboid structure, the internal space of the storage frame 3 can accommodate the solid lubricant 200 equal to the number of circumferential blind holes of the oilless bushing 100, so as to facilitate the single filling of the machining preparation of the whole circle blind hole on the oilless bushing 100, the base 12 corresponding to the receiving plate 6 is connected to the bottom of the storage frame 3, a plurality of lifting seats 13 stacked below the base 12 are arranged, the lifting seats 13 are arranged on the workbench 1, the height of the lifting seats 13 is consistent with the interval of the adjacent two blind holes in the height direction of the oilless bushing 100, the number of the lifting seats 13 is consistent with the number of the blind holes in the height direction of the oilless bushing 100, and the number of the solid lubricants 200 contained in the storage frame 3 is consistent with the number of the circumferential blind holes on the oilless bushing 100.

[0022] Working principle: the staff arranges multiple solid lubricants 200 from the mixing basin to the distributor 4, and then transfers multiple solid lubricants to the storage frame 3 through the distributor 4 and arranges them neatly in the storage frame 3, and moves the push rod 9 in the guide hole 8, and pushes the corresponding solid lubricant out of the discharge port 7 and into the blind hole of the corresponding oilless bushing 100.

[0023] After the push rod 9 is reset under the action of the spring 11, the fixed lubricant in the storage frame 3 falls under the action of gravity and corresponds to the push rod 9. The design of the rotating disc 2 enables the oil-free bushing 100 to rotate as needed. By rotating the rotating disc 2, the next blind hole in the circumferential position of the oil-free bushing 100 corresponds to the discharge port 7. By repeating the operation of pushing the push rod 9, the embedding of the solid lubricant 200 in the blind hole in the circumferential position of the oil-free bushing 100 is sequentially completed, and the embedding of the solid lubricant 200 is continuously and quickly completed, which is beneficial to improve the embedding efficiency of the solid lubricant 200 and reduce the labor burden of the workers.

[0024] By matching the removal of one lifting seat 13 to lower the position of the discharge port 7, the discharge port 7 corresponds to the adjacent blind hole in the height direction of the oil-free bushing 100.

When the oil-free bushing 100 rotates, the end of the L-shaped silica gel rod 5 moves on the outer wall of the oil-free bushing 100. When the end of the L-shaped silica gel rod 5 moves to the adjacent next blind hole, the end of the L-shaped silica gel rod 5 returns to its original state and enters the blind hole to quickly position the rotation angle of the oil-free bushing 100. During the rotation of the rotating disc 2 to drive the rotation of the oil-free bushing 100, the next blind hole to be embedded can be quickly corresponded to the discharge port 7, which is beneficial to improve the embedding efficiency.

The distance between the two side plates 31 is slightly greater than the diameter of the solid lubricant 200.

[0028] The front plate 32 is provided with an outlet 7 which forms an accurate alignment channel with the guide hole 8 of the rear plate 33, cooperates with the linear motion track of the push rod 9, and guarantees that the solid lubricant 200 can be accurately pushed into the blind hole of the oil-free bushing 100 each time. The distance between the two side plates 31 is slightly larger than the diameter of the solid lubricant 200, which can guarantee that the solid lubricant 200 is kept in a vertical arrangement in the storage frame 3, and can also avoid the frictional jamming phenomenon caused by too small gap, and ensure the smooth falling of the lubricant under the action of gravity.

[0029] The push rod 9 is provided with a limiting plate 10, the limiting plate 10 is provided with a spring 11, the spring 11 is connected with the rear plate 33, and the spring 11 is arranged so that the push rod 9 can be automatically reset after pushing out the solid lubricant 200, thereby improving the continuity and efficiency of operation.

[0030] The receiving plate 6 is provided with a guide groove 61 which is convenient for the solid lubricant 200 to move to the outlet 7, and the guide groove 61 can help to guide the solid lubricant 200 to be more quickly and accurately transferred to the outlet 7, reduce the retention of the lubricant in the storage frame 3, and improve the overall embedding efficiency.
