Detailed Description
The following detailed description of the embodiments of the present invention will be provided in conjunction with the accompanying drawings and examples, so that how to implement the embodiments of the present invention by using technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.
Referring to fig. 1, fig. 1 is a schematic diagram of a precisely positioned hole drill according to an embodiment of the present invention.
As shown, a precisely positioned hole drill, comprising: a connecting column 10; a mounting post 20 disposed above the connecting post 10; the drill barrel part 30 is arranged below the connecting column 10, chip removing holes 31 with uniform intervals are formed in the side wall of the drill barrel part 30, a drill bit 32 is arranged at one circle of the end part of the drill barrel part 30, and a positioning support mounting hole 33 is formed in the drill barrel part 30; a locating bracket 40 disposed within the drill barrel portion 30, the locating bracket 40 comprising: the support seat body 41 is installed in the positioning support mounting hole 33, the spring 42 is arranged in the support seat body 41, and the support column 43, a seat body flange 411 is arranged at the end part of the support seat body 41, a column flange 431 is arranged at one end of the support column 43, a positioning frustum 432 is arranged at the other end of the support column 43, one end of the spring 42 is abutted against the bottom of the positioning support mounting hole 33, and the other end of the spring 42 is abutted against the column flange 431.
In one embodiment of the present invention, a mounting post 20 is disposed above the connecting post 10, and the diameter of the connecting post 10 is larger than the diameter of the mounting post 20. The mounting post 20 has a mounting hole 21 for mounting a hole drill on a power tool.
A drill cylinder part 30 is arranged below the connecting column 10, and chip removal holes 31 with uniform intervals are arranged on the side wall of the drill cylinder part 30. Preferably, the chip removal holes 31 are provided with 4 groups for chip removal during drilling. The drill cylinder 30 has a drill bit 32 at one end thereof, and performs drilling while rotating. The drill cylinder portion 30 is provided with a positioning bracket mounting hole 33.
A positioning bracket 40 is provided in the drill barrel portion 30, and the positioning bracket 40 includes: a bracket body 41 installed in the positioning bracket installation hole 33, a spring 42 provided in the bracket body 41, and a bracket column 43. The bracket body 41 is connected with the positioning bracket mounting hole 33 through a thread, and a body flange 411 is arranged at the end of the bracket body 41. One end of the bracket column 43 is provided with a column flange 431, and the other end of the bracket column 43 is provided with a positioning frustum 432.
