Abstract
The invention relates to a chamfered drilling structure, which consists of a hand-held rod (1) and a counter bit (2), wherein the lower part of the hand-held rod (1) is connected to the counter bit (2). According to the chamfered drilling structure, during drilling, people can manually achieve chamfering by a chamfered drill without using a drilling machine; a rotation workpiece is not required so that time and energy are greatly saved; friction of the bottom of the workpiece against a platform surface is reduced so that the appearance quality of the workpiece is improved; and processing time is reduced and electric charge is saved, so that the processing cost is reduced.
Description
Technical field
The invention belongs to the processing technology field, be specifically related to a kind of chamfer drill structure.
Background technology
At present, chamfering is to realize by upright drill under the regular situation, but the shortcoming of the existence of common process design is: take the very long working time; On upright drill, during chamfering, need to remove mating holes by eyes, and need the rolling brake drum behind hole of chamfering, consume greatly muscle power, and affect bottom surface roughness and bottom surface outward appearance because workpiece bottom is understood with the flat surface friction.
Summary of the invention
The present invention is in order to solve the deficiency of above-mentioned existence, and then a kind of chamfer drill structure is provided, and this structure does not need turning of work piece, saved to a great extent time and muscle power and reduced the friction of workpiece bottom and flat surface, improved the workpiece presentation quality.
Technical scheme of the present invention: a kind of chamfer drill structure, it is comprised of holding rod 1 and counterbit 2, and the bottom of holding rod 1 is connected with counterbit 2.
The present invention compared with prior art has following beneficial effect: do not need drilling machine, the human chamfer drill can be finished chamfering by hand; Do not need turning of work piece, very large time and the muscle power of having saved; Reduce the friction of workpiece bottom and flat surface, improved the workpiece presentation quality; Reduce process time, saved the electricity charge, reduced processing cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
A kind of chamfer drill structure, it is comprised of holding rod 1 and counterbit 2, and the bottom of holding rod 1 is connected with counterbit 2.When the people uses chamfer drill, do not need turning of work piece, very large time and the muscle power of having saved has reduced the friction of workpiece bottom and flat surface, has reduced process time, has improved the workpiece presentation quality.
Claims (1)
