Abstract
The utility model discloses a drill for drilling and spot facing in one step, which relates to the field of machining equipment. The drill for drilling and spot facing in one step comprises a clamping part and a working part and is characterized in that the tail end of the working part takes the shape of a step. The drill for drilling and spot facing in one step is simple in structure and low in manufacturing cost; being formed by grinding a common waste drill, the drill for drilling and spot facing in one step is capable of realizing the recycle of wastes; as the drilling and the spot facing are carried out in one step, the machining efficiency is improved and the machining cost is reduced; and the coaxiality between a countersink and an original hole can be ensured, so that the rejection rate is reduced.
Description
Technical field:
The utility model relates to the machining equipment field, is specifically related to a kind of boring, spot-facing one-shot forming drill bit.
Background technology:
A lot of workpiece need spot-facing after boring, so just need after boring, carry out the spot-facing operation.But when being to use radial drilling machine to carry out the spot-facing operation, be difficult to guarantee the axiality in counterbore and original hole, position of related features is big, is prone to waste product.
The utility model content:
The utility model technical problem to be solved is to provide boring, spot-facing one-shot forming drill bit a kind of simple in structure, easy to use.
The utility model technical problem to be solved adopts following technical scheme to realize,
A kind of boring, spot-facing one-shot forming drill bit comprise clamping part and working portion, it is characterized in that: the terminal one-tenth of said working portion is step-like.
The utility model is simple in structure, and low cost of manufacture grinds with the common drill bit of scrapping and to form; The recycling of realization waste product, boring, spot-facing one-shot forming have improved working (machining) efficiency; Reduce processing cost, and can guarantee the axiality in counterbore and original hole, reduced percent defective.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with specific embodiment and diagram, further set forth the utility model.
As shown in Figure 1, a kind of boring, spot-facing one-shot forming drill bit comprise clamping part 1 and working portion 2, and working portion 2 terminal one-tenth are step-like.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
