However, it should be understood that these descriptions are only for further explaining the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0015] The utility model is further described below in conjunction with the drawings and preferred embodiments.

[0016] Embodiment 1

[0017] See Figures 1 to 3As shown in the figure, a drilling tooling involved in this embodiment includes a bottom plate 1 and a top plate 2 arranged above the bottom plate. A column 3 is connected between the top plate 2 and the bottom plate 1. A chuck 4 for clamping a workpiece is provided on the bottom plate 1. A core plate 5 in a cylindrical shape and coaxially arranged with the chuck is provided on the top plate 2, and an annular plate 6 coaxially arranged with the core plate 5. The annular plate 6 is arranged outside the core plate 5. The core plate 5 is fixedly connected to the top plate 2. The annular plate 6 is rotatably connected to the top plate 2. A gap 7 is left between the annular plate 6 and the core plate 5. A number of adjusting holes 8 extending radially and penetrating through the top plate 2 are circumferentially arranged on the core plate 5. An adjusting block 9 is slidably connected in the adjusting hole 8. A drill hole 10 is formed in the adjusting block 9, and a wear-resistant drill sleeve (not marked) is inserted in the drill hole 10. An elastic member 11 is provided at the inner end of the adjusting block 9, and a driving column 12 extending radially along the core plate is provided at the outer end. The driving column 12 is slidably connected to the core plate 5. One end of the driving column 12 is connected to the adjusting block, and the other end extends into the gap and abuts against the annular plate 6. One end of the elastic member 11 abuts against the hole wall of the adjusting hole, and the other end abuts against the adjusting block. A guiding slope block 13 provided on the annular plate 6 is arranged on the same side of the driving column 12. A handle 14 for controlling rotation is provided on the annular plate 6.

[0018] Further, the included angle between adjacent two adjusting holes 8 is equal.

[0019] Further, the elastic member 11 is a compression spring.

[0020] In this embodiment, a rotating workpiece to be drilled at the end face is clamped by the chuck 4. By using the handle 14, the annular plate 6 can be driven to rotate relative to the core plate 5. During the rotation, the guiding slope block 13 on the annular plate 6 will slide into the inner side of the annular plate 6 and between the driving columns 12, thereby pushing the driving column 12, so that the driving column 12 drives the adjusting block 9 to slide in the adjusting hole 8, thus changing the position state of the drill hole 10 in the adjusting hole 8. After the adjustment is completed, each drill hole 10 is used for drilling the end face of the workpiece.

[0021] Among them, through the setting of the elastic member 11, after the guiding slope block 13 is manually combined, the driving column 12 is used for automatic reset.

[0022] Embodiment 2

[0023] See Figures 1 to 3As shown in the figure, a drilling tooling involved in this embodiment is further configured, on the basis of Embodiment 1, such that the handle 14 extends along the radial direction of the annular plate 6; an activity gear hole 15 is formed on the handle 14, and at least three fixed gear holes 16 arranged at equal angular intervals along the circumferential direction of the core plate are formed on the top plate 2. The fixed gear holes 16 match the activity gear hole 15. A limit pin 17 is inserted into the activity gear hole 15 and one of the fixed gear holes 16, and a retaining piece 18 for restricting the downward fall is arranged at the top of the limit pin 17.

[0024] Furthermore, a finger ring 19 is arranged at the top of the retaining piece 18.

[0025] In this implementation scheme, through the combined setting of the activity gear hole 15, the fixed gear hole 16 and the limit pin 17, it is used for positioning the handle 14 after adjusting the annular plate 6.

[0026] Among them, through the setting of the retaining piece 18, the inserted limit pin 17 is prevented from falling naturally.

[0027] Among them, through the setting of the finger ring 19, it is used for the finger to extend in, which is convenient for taking and placing the limit pin 17.

[0028] The drilling tooling involved in the present utility model rotates the annular plate relative to the core plate, so that the guiding slope block on the annular plate pushes the driving column, so as to change the radial position of the drill hole in the adjusting hole, so that the tooling can be used for drilling rotating parts with different process requirements. The adjustment is convenient, the versatility is strong, the overall function is perfect, and the practicability is strong.
