Description
Technical field
The utility model belongs to full aluminium household technical field, is related to a kind of deburring drill bit of shape extrusion.
Background technique
Full aluminium furniture has many advantages, such as that durable, texture is excellent, environmentally friendly with aluminium generation wood, in recent years by consumer blueness
It looks at.
During profile material assembling, since connection needs, it can drill on profile often, in the outer end opening in hole after drilling
Locate burr easy to form, due to being in the assembling stage, the burr on profile seriously affects the overall performance of furniture, but straight
It connects and then be easy to cause the lacquer painting of polishing region larger area impaired with sand paper polishing, so need one kind direct in drilling
Flash removed is removed, and does not damage the drill bit of lacquer painting.
Utility model content
The purpose of this utility model is aiming at the above problems existing in the prior art, to provide a kind of going for shape extrusion
Burr drill bit, technical problem to be solved in the utility model are to strike off drilling how under the premise of not influencing profile lacquer painting
When the burr that is formed.
The purpose of this utility model can be realized by the following technical scheme: a kind of deburring drill bit of shape extrusion,
It is characterized in that, this deburring drill bit includes mounting portion, shank and cutter head, the shank connects mounting portion and cutter head, the peace
Mounting hole is offered in dress portion, the briquetting of a round pie is inserted in the mounting hole, between the briquetting and inner wall of the hole installing
It is connected by a spring, the lower end of the briquetting is provided with a scraping blade, and the mounting hole runs through the lower surface of mounting portion, the handle
The upper end in portion has a notch, and the notch is communicated with mounting hole, and the scraping blade can be plugged in notch, the width of the scraping blade
The ratio of degree and the diameter of shank is 1:0.9.
The width of scraping blade is slightly larger than the diameter of shank, makes this drill bit in drilling, scraping blade is capable of at the upper end opening of device to hole
It carries out scraping flash removed, and under the action of the spring, the dynamics struck off is relatively small, will not influence the shape in hole, to Surface of profile
Lacquer painting degree of injury it is minimum.
In a kind of deburring drill bit of above-mentioned shape extrusion, it is threaded at the upper end opening of the mounting hole
One plug, the spring are resisted against between plug and briquetting.
Scraping blade and briquetting are installed by plug, also the pretightning force of adjustable spring.
In a kind of deburring drill bit of above-mentioned shape extrusion, the upper end of the mounting hole is the circle being adapted to briquetting
The lower end in shape hole, the mounting hole is the flat hole being adapted to scraping blade, and the notch is communicated with the lower end of mounting hole.
Scraping blade can not rotate in mounting hole, reliable when it being made to scrape flash removed.
Detailed description of the invention
Fig. 1 is the sectional view of this drill bit.
In figure, 1, mounting portion；2, shank；3, cutter head；4, mounting hole；5, briquetting；6, spring；7, notch；8, plug；9, it scrapes
Piece.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, this deburring drill bit includes mounting portion 1, shank 2 and cutter head 3, shank 2 connects mounting portion 1 and cutter head
3, offer mounting hole 4 in mounting portion 1, be inserted with the briquetting 5 of a round pie in mounting hole 4, briquetting 5 and 4 inner wall of mounting hole it
Between be connected by a spring 6, the lower end of briquetting 5 is provided with a scraping blade 9, and mounting hole 4 runs through the lower surface of mounting portion 1, shank 2
Upper end has a notch 7, and notch 7 is communicated with mounting hole 4, and scraping blade 9 can be plugged in notch 7, the width and shank 2 of scraping blade 9
Diameter ratio be 1:0.9.
The width of scraping blade 9 is slightly larger than the diameter of shank 2, makes this drill bit in drilling, scraping blade 9 is capable of the upper end opening of device to hole
Place carries out scraping flash removed, and under the action of spring 6, the dynamics struck off is relatively small, will not influence the shape in hole, to profile table
The degree of injury of the lacquer painting in face is minimum.
A plug 8 is threaded at the upper end opening of mounting hole 4, spring 6 is resisted against between plug 8 and briquetting 5.Pass through
Plug 8 installs scraping blade 9 and briquetting 5, also the pretightning force of adjustable spring 6.
The upper end of mounting hole 4 is the round hole being adapted to briquetting 5, and the lower end of mounting hole 4 is flat to be adapted to scraping blade 9
Hole, notch 7 are communicated with the lower end of mounting hole 4.Scraping blade 9 can not rotate in mounting hole 4, reliable when it being made to scrape flash removed.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
