[0024] This specific embodiment is a high-precision tap protection chuck, the structural diagram of which is shown below. Figures 1-5 As shown, it includes a circular cylinder 1, a slidable protective cover 2 on the outside of the circular cylinder 1, a circular mounting part 3 inside the circular cylinder 1, a plurality of movable gripping fingers 11 inside the circular mounting part 3, and a moving mechanism for moving the gripping fingers 11 on the outside of the circular mounting part 3.

[0025] An annular movable plate 5 is slidably connected to the outside of the cylindrical cylinder 1 and inside the protective cover 2. The outside of the annular movable plate 5 is fixedly connected to the protective cover 2. An annular fixed plate 4 is fixed to one end of the outer side of the cylindrical cylinder 1. Multiple transverse rigid springs 6 are provided between the annular fixed plate 4 and the annular movable plate 5.

[0026] The annular moving plate 5 has a circular groove inside. The annular moving plate 5 is slidably connected to the circular cylinder 1 through the circular groove. The circular groove allows the annular moving plate 5 to slide on the outside of the circular cylinder 1. The sliding of the annular moving plate 5 causes the transverse rigid spring 6 to deform under force.

[0027] The annular moving plate 5 has multiple rectangular sliders fixed inside, and the cylindrical cylinder 1 has rectangular grooves that are adapted to the rectangular sliders inside. The annular moving plate 5 and the cylindrical cylinder 1 are slidably connected through the cooperation of the rectangular sliders and the rectangular grooves. Through the cooperation of the rectangular sliders and the rectangular grooves, the annular moving plate 5 can move laterally on the outside of the cylindrical cylinder 1, thereby preventing the annular moving plate 5 from rotating on the outside of the cylindrical cylinder 1.

[0028] Here, when it is necessary to clamp the tap, the protective cover 2 is pushed. The pushing of the protective cover 2 allows the annular moving plate 5 to slide on the outside of the cylindrical cylinder 1. The sliding of the annular moving plate 5 causes the transverse rigid spring 6 to contract under force, thereby allowing the clamping fingers 11 to protrude from the inside of the protective cover 2 so that the clamping fingers 11 can clamp the tap. After clamping is completed, the pushing of the protective cover 2 is released. Through the elastic characteristics of the transverse rigid spring 6, the annular moving plate 5 can slide on the outside of the cylindrical cylinder 1, so that the protective cover 2 can prevent the tap from slipping and greatly reduce the amount of dust entering the outside of the cylindrical cylinder 1.

[0029] The moving mechanism includes an annular rotating component 7. One end of the cylindrical cylinder 1 is rotatably connected to the annular rotating component 7. The bottom of the annular rotating component 7 is rotatably connected to the circular mounting component 3 via a bearing. The bottom of the annular rotating component 7 is engaged with the clamping finger 11. A bevel gear 8 is engaged with the outer side of the annular rotating component 7.

[0030] The circular mounting component 3 has a circular through hole inside. The clip 11 is located inside the circular through hole and is slidably connected to the circular mounting component 3 through the circular through hole. The circular through hole allows the clip 11 to slide inside the circular mounting component 3.

[0031] The bottom of the annular rotating part 7 is provided with a gear block, and the inside of the clamping finger 11 is provided with a gear groove that matches the gear block. The annular rotating part 7 and the clamping finger 11 are connected by the meshing of the gear block and the gear groove. Through the meshing of the gear block and the gear groove, the clamping finger 11 can slide inside the circular mounting part 3.

[0032] A vertical rotating rod 9 is fixed inside the bevel gear 8. A transverse insert rod 10 is slidably connected inside the vertical rotating rod 9. The bottom of the vertical rotating rod 9 is located inside the circular mounting part 3 and is rotatably connected to the circular mounting part 3 through a bearing. This allows the vertical rotating rod 9 to drive the bevel gear 8 to rotate. The transverse insert rod 10 facilitates the rotation of the vertical rotating rod 9, so that the rotation of the bevel gear 8 can drive the annular rotating part 7 to rotate.

[0033] Here, by rotating the transverse insertion rod 10, the vertical rotating rod 9 can rotate inside the circular mounting part 3. The rotation of the vertical rotating rod 9 causes the bevel gear 8 to rotate, and the rotation of the bevel gear 8 causes the annular rotating part 7 to rotate outside the circular mounting part 3. The rotation of the circular mounting part 3 is connected to the circular mounting part 3 by the meshing of the clamping finger 11, so that the clamping finger 11 can slide inside the circular mounting part 3, thereby facilitating the clamping finger 11 to clamp the tap.

[0034] Working principle: When using the chuck of this technical solution, when it is necessary to clamp the tap, the protective cover 2 is pushed. The pushing of the protective cover 2 causes the annular moving plate 5 to slide on the outside of the cylindrical cylinder 1. The sliding of the annular moving plate 5 causes the transverse rigid spring 6 to be compressed, thereby allowing the clamping fingers 11 to protrude from the inside of the protective cover 2 so that the clamping fingers 11 can clamp the tap.

[0035] By rotating the transverse insertion rod 10, the vertical rotating rod 9 can rotate inside the circular mounting part 3. The rotation of the vertical rotating rod 9 causes the bevel gear 8 to rotate. The rotation of the bevel gear 8 causes the annular rotating part 7 to rotate outside the circular mounting part 3. The rotation of the circular mounting part 3 is connected to the circular mounting part 3 by the meshing of the clamping finger 11, so that the clamping finger 11 can slide inside the circular mounting part 3, thereby facilitating the clamping finger 11 to clamp the tap.

[0036] After clamping is complete, release the push on the protective cover 2. Through the elastic characteristics of the transverse rigid spring 6, the annular moving plate 5 can slide on the outside of the cylindrical cylinder 1, so that the protective cover 2 can prevent the tap from slipping and greatly reduce dust from entering the outside of the cylindrical cylinder 1.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
