[0020] Example 1
[0021] Please refer to the following: Figures 1-5 This utility model discloses a retractable and concealable guide sleeve base for deep hole drilling, comprising: a drill bit frame 1, a first double guide rail 2 horizontally mounted on one side of the drill bit frame 1, a drill bit mounting base 3 connected to the first double guide rail 2, a retractable concealment opening 6 on the side of the drill bit frame 1 near the drill bit mounting base 3, a second double guide rail 7 mounted on the side of the drill bit frame 1 near the retractable concealment opening 6, a movable frame plate 8 connected to the second double guide rail 7, a movable guide rail 9 horizontally mounted on one side of the movable frame plate 8, a drill rod guide sleeve 10 and a protective sleeve 11 connected to the movable frame plate 8 via the movable guide rail 9, a fixed guide rail 12 horizontally mounted on the side of the drill bit frame 1 near the first double guide rail 2, the fixed guide rail 12 corresponding to the movable guide rail 9, wherein there are three fixed guide rails 12 and three movable guide rails 9, arranged horizontally in an upper, middle and lower order, and the drill rod guide sleeve 10 is connected to the upper and lower guide rails, the protective sleeve 11 is connected to the middle guide rail, and the protective sleeve 11 can move along the middle guide rail.
[0022] Specifically, when a milling cutter is needed to process a workpiece, the drill rod guide sleeve 10 and the protective sleeve 11 are moved along the fixed guide rail 12 to the movable guide rail 9 at the movable frame plate 8. Then, they can move back along the second double guide rail 7 to the movable frame plate 8, so that the movable frame plate 8, together with the drill rod guide sleeve 10 and the protective sleeve 11, retracts into the retraction concealment opening 6. The milling cutter can then be installed through the drill bit chuck 5, and the threaded rod 17 is driven to rotate by the second drive motor 16. The threaded rod 17 then drives the drill bit mounting base 3 to move along the first double guide rail 2 toward the workpiece to perform the processing operation.
[0023] Example 2
[0024] Combination Figure 3 As shown, a drill bit rotating shaft 4 is rotatably connected inside the drill bit mounting base 3. A drill bit clamp 5 is provided at one end of the drill bit rotating shaft 4 facing the drill rod guide sleeve 10. A geared disc 14 is provided at one end of the drill bit rotating shaft 4 inside the drill bit mounting base 3. A first drive motor 15 is fixedly installed on one side of the geared disc 14 in the drill bit mounting base 3. The output end of the first drive motor 15 is connected to a gear, and the gear is connected to the geared disc 14 through a chain. The first drive motor 15 can drive the geared disc 14 to rotate, and thus the geared disc 14 drives the drill bit rotating shaft 4 to rotate. The guide sleeve 10, protective sleeve 11, and drill bit rotation shaft 4 are coaxial. A shock-absorbing rubber ring is installed inside the protective sleeve 11. A second drive motor 16 is fixedly mounted on the drill bit holder 1 near the end of the first drive motor 15. A threaded rod 17 is connected to the output end of the second drive motor 16. The threaded rod 17 is threaded through and connected to the drill bit mounting base 3. The end of the threaded rod 17 is connected to one side of the drill bit holder 1 via a bearing. The drill bit guide sleeve 10 and the protective sleeve 11 are fitted together and movably connected to the drill bit 13. The tail of the drill bit 13 is clamped inside the drill bit chuck 5. The second double guide rail 7, fixed guide rail 12, and movable guide rail 9 are all HIWIN type linear guide rails. Both the first drive motor 15 and the second drive motor 16 are connected to the equipment's control switch via wires. The shock-absorbing rubber ring in the protective sleeve 11 reduces the vibration generated when the drill bit 13 rotates during drilling.
[0025] Specifically, the drill rod guide sleeve 10 and the protective sleeve 11 are moved along the fixed guide rail 12 to the movable guide rail 9 at the movable frame plate 8. The movable frame plate 8 at the retraction concealment opening 6 can be moved along the second double guide rail 7, so that the movable frame plate 8, together with the drill rod guide sleeve 10 and the protective sleeve 11, extends out of the retraction concealment opening 6. When it is moved into place, the movable guide rail 9 is connected with the fixed guide rail 12 (at this time, the drill rod guide sleeve 10, the protective sleeve 11 and the drill bit rotation shaft 4 are coaxial). Then, the drill bit rod 13 of the deep hole drill can pass through the inside of the drill rod guide sleeve 10 and the protective sleeve 11 and be clamped in the drill bit clamp 5, so that the rotation of the drill bit rod 13 can be kept stable.
[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
[0027] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
