[0019] Please refer toFigures 1-5 As shown in the figure, a drilling device for the production of an oil cylinder connecting sleeve includes a base 1. On both sides of the top end of the base 1, there are support frames 2. At the top ends of the support frames 2, two groups of first motors 3 are installed. The output end of the first motor 3 passes through the top end of the support frame 2 and is connected to a threaded column 5. The other end of the threaded column 5 is connected to the base 1. The outer part of the threaded column 5 is rotationally connected to a second top plate 12. A threaded hole 13 is opened inside the second top plate 12, and the inner diameter of the threaded hole 13 is the same as that of the threaded column 5. One end of the second top plate 12 is welded to connect a placing opening 8, and a sliding plate 9 is opened at the center of the placing opening 8. Between the top ends of the two groups of support frames 2, a first top plate 11 is welded. A through hole 10 is opened at the center of the first top plate 11. A second motor 4 is installed at the top end of the through hole 10. The output end of the second motor 4 passes through the through hole 10 and is connected to a driving shaft 14. A slide rail 20 is welded to the outer part of the driving shaft 14. A support plate 21 is welded to the outer part of the bottom end of the second motor 4. At both ends of the bottom of the support plate 21, there are two groups of connecting shafts 25. A connecting plate 22 is connected to the outer part of the connecting shaft 25. The other end of the connecting plate 22 is connected to a positioning block 24. The other end of the positioning block 24 is welded to connect a grinding block 17. When drilling the connecting sleeve, at this time, the operator places the connecting sleeve at the placing opening 8. Then, by starting the second motor 4, the second motor 4 drives the drill bit 18 to rotate. Then, start the two first motors 3 on both sides. At this time, the first motor 3 drives the threaded column 5 to rotate. And due to the rotational connection relationship between the threaded column 5 and the second top plate 12, the second top plate 12 starts to drive the central sliding plate 9 to rise. Then, through the continuous rise of the sliding plate 9, the central connecting sleeve contacts the drill bit 18. Then, the drilling operation can be started. When the drilling is completed, by retracting the sliding plate 9 and lowering the sliding plate 9, the deburring operation is carried out while the feeding operation is carried out.

[0020] The bottom of the driving shaft 14 is welded to a drill bit 18, and the drill bit 18 is located just above the storage port 8; a protective ring 6 is provided on the outside of the driving shaft 14, and a protective tube 7 is welded to the bottom of the protective ring 6, and a slide groove 23 is provided inside the protective tube 7, and the slide groove 23 is slidably connected to the slide rail 20; four groups of support rods 15 are welded to the bottom of the protective tube 7, and a positioning plate 16 is welded to the center of the support rod 15; the bottom of the support rod 15 is provided with the same structural design as the bottom of the driving shaft 14, and the grinding blocks 17 between the two groups of structures are staggered and relatively sealed; when deburring the connecting sleeve, when drilling, the position at this time The two groups of grinding blocks 17 at the bottom of the drive shaft 14 will penetrate the connecting sleeve under the lifting operation of the slide plate 9, and then the operator will lift the protective ring 6. At this time, the grinding blocks 17 at the bottom of the protective tube 7 will be lifted so that the two sides of the grinding blocks 17 are close to the two sides of the grinding blocks 17 at the bottom of the drive shaft 14 and are inserted into the gap therebetween. At this time, a closed loop is formed between the two groups of grinding blocks 17, thereby fixing the position of the device at the bottom of the connecting sleeve. Then, the No. 2 motor 4 is started, so that the slide rail 20 drives the slide groove 23, and the protective tube 7 rotates, and the burrs on the bottom of the connecting sleeve are ground by the two groups of grinding blocks 17 at the bottom. In this way, the deburring operation of the connecting sleeve is completed.

[0021] Working principle, when drilling the connecting sleeve, the operator places the connecting sleeve at the storage port 8, and then starts the No. 2 motor 4 to drive the drill bit 18 to rotate, and then starts the No. 1 motor 3 on both sides. At this time, the No. 1 motor 3 drives the threaded column 5 to rotate, and due to the rotational connection between the threaded column 5 and the No. 2 top plate 12, the No. 2 top plate 12 starts to drive the center slide plate 9 to rise, and then the slide plate 9 continues to rise, so that the center connecting sleeve contacts with the drill bit 18, and then the drilling operation can be started. When the drilling is completed, the slide plate 9 is retracted and the slide plate 9 is lowered to perform the deburring operation at the same time as the material withdrawal operation; when deburring the connecting sleeve, when drilling, the bottom of the drive shaft 14 is at this time. The two groups of grinding blocks 17 at the bottom will penetrate the connecting sleeve under the lifting operation of the slide plate 9, and then the operator will lift the protective ring 6. At this time, the grinding blocks 17 at the bottom of the protective tube 7 will make the two sides of the grinding blocks 17 close to the two sides of the grinding blocks 17 at the bottom of the driving shaft 14 under the action of lifting, and fill the gap therein. At this time, a closed loop is formed between the two groups of grinding blocks 17, so that the position of the device is fixed at the bottom of the connecting sleeve, and then the No. 2 motor 4 is started to make the slide rail 20 drive the slide groove 23, and the protective tube 7 rotates, and the burrs on the bottom of the connecting sleeve are ground by the two groups of grinding blocks 17 at the bottom, and the deburring operation of the connecting sleeve is completed in this way; then stop the No. 2 motor 4 and press the protective ring 6 to perform the convergence operation on the grinding blocks 17.
