DETAILED DESCRIPTION

[0016] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments. Example

[0017] like Figure 1-3As shown, the utility model proposes an adjustable angle rotary clamping device for drilling special-shaped holes, including a base 1, a fixed frame 11 is fixed to the rear side of the upper end of the base 1, the upper end of the fixed frame 11 is rotatably connected to the rotating frame 12, the front side of the rotating frame 12 is slidably connected to the drilling rig 2, and the upper end of the rotating frame 12 is fixed with a telescopic cylinder 21 for driving the drilling rig 2 to rise and fall. A group of columns 3 are fixed to the upper end of the columns 3, a fixed plate 31 is fixed to the upper end of the fixed plate 31, and the upper end of the rotating plate 4 is rotatably connected to the rotating plate 4, the upper end of the rotating plate 4 is slidably connected to the sliding block 41 through the driving assembly 6, and the upper end of the sliding block 41 is fixed with a three-jaw chuck 42, a rotating assembly 5 is arranged between the fixed frame 11 and the rotating frame 12, and the upper outer periphery of the rotating plate 4 is threadedly connected to a locking bolt 43, and the bottom of the locking bolt 43 is against the fixed plate 31.

[0018] The rotating assembly 5 includes a worm wheel 51 and a worm 52. The worm wheel 51 is fixed to the outer periphery of the bottom of the rotating frame 12. The worm 52 is inside the fixed frame 11 and passes through the fixed frame 11 and is rotatably connected. The worm 52 is engaged with the worm wheel 51. A mounting frame 53 is fixed at the upper end of the base 1 and located at both ends of the worm 52. The worm 52 is rotatably connected between the mounting frames 53. A servo motor 54 is fixed to the outside of the mounting frame 53, and the output end of the servo motor 54 is fixed to the end of the worm 52.

[0019] The driving assembly 6 includes a sliding groove 61 and a rotating plate 63. The sliding groove 61 is opened in the middle position of the upper end of the rotating plate 4. The bottom of the sliding block 41 is slidably connected to the sliding groove 61. A threaded rod 62 is rotatably connected in the sliding groove 61. The threaded rod 62 passes through the bottom of the sliding block 41 and is threadedly connected to the bottom of the sliding block 41. The rotating plate 63 is rotatably connected to the outer periphery of the rotating plate 4, and its position is aligned with the threaded rod 62. The end of the threaded rod 62 extends through the sliding groove 61 and is fixed on the rotating plate 63.

[0020] In this embodiment, the entire device is first connected to an external power supply, and then the three-jaw chuck 42 is used to fix the workpiece. The rotation of the rotating plate 4 and the sliding of the sliding block 41 are used to adjust the alignment of different drilling positions of the workpiece with the drill 2 to achieve drilling processing at different positions. When the rotating plate 4 rotates, the locking bolt 43 can be loosened. Conversely, after rotating to the specified position, the position of the rotating plate 4 can be fixed by tightening the locking bolt 43. The rotation of the rotating plate 63 can drive the threaded rod 62 to rotate, so that the sliding block 41 can slide linearly along the sliding groove 61. Finally, different positions on the workpiece can be rotated to align with the drill 2 without multiple clamping. When inclined hole processing is required, the rotation of the rotating frame 12 can be used to form a certain angle between the drill 2 and the three-jaw chuck 42. Then, the drill 2 is started to achieve oblique drilling processing. During this process, the output end of the servo motor 54 is used to drive the worm 52 to rotate, and the transmission of the worm gear 51 is not used to finally achieve the rotation drive of the rotating frame 12.
