Description
Technical Field
The utility model relates to a woodworking tool, in particular to a woodworking tool with drilling and reaming combined functions.
Background
Along with the gradual improvement of the living standard of people, the quality requirements on doors, windows and furniture are higher and higher, and the high-quality furniture not only comprises the improvement of materials and processes, but also means higher processing precision. At present, in the field of assembling furniture, the assembling of each part of the furniture is basically realized through wood pins, and the machining precision of pin holes is very important. When the wooden furniture is punched, because the wood has certain elasticity, most drilled holes shrink, and therefore, the existing high-grade assembled furniture mostly adopts the process of drilling and then reaming, so that high assembly precision is obtained, but a process is added in the manufacturing process, and the efficiency is difficult to improve.
Disclosure of Invention
To the problem in the background art, the utility model aims at providing a carpenter's cutter with brill hinge combined function, the cutter has the function of drilling and reaming simultaneously, can merge the twice process of pinhole processing into one process, and the required precision of original twice process is satisfied in the pinhole that processes out to on the basis that promotes the product precision, improve machining efficiency.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a woodworking tool with compound function drills and reams, includes stalk portion, reaming portion, drill bit, linkage segment A and the linkage segment B of coaxial setting, its upper portion of stalk portion be connected with the lathe main shaft, its lower part is passed through linkage segment A and is solid as an organic whole with reaming portion, the lower extreme of reaming portion is passed through linkage segment B and is solid as an organic whole with the drill bit, the diameter of reaming portion is greater than the drill bit diameter, the diameter of linkage segment A, linkage segment B all is less than the drill bit diameter, its apex angle of drill bit be 80 ~ 100 degrees.
The difference between the diameter of the reaming part and the diameter of the drill bit is less than or equal to 0.2 mm.
The apex angle of the drill bit is 90 degrees.
The helix angle of the cutting edge of the reaming part is 2-3 degrees.
The utility model has the advantages that: the utility model is suitable for a wood working can carry out the reaming in the drilling, unites two into one the twice process, has saved a clamping of tool changing or work piece, has improved machining efficiency, and simultaneously, the design of cutter accords with wood working's characteristics, can obtain good machining precision under higher process velocity.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a view a-a of fig. 1.
In the figure, 1, a handle part, 2, a reaming part, 3 and a drill bit.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the woodworking tool with the drilling and reaming combined function comprises a handle part 1, a reaming part 2, a drill bit 3, a connecting section a4 and a connecting section B5 which are coaxially arranged, wherein the upper part of the handle part 1 is connected with a machine tool spindle, the lower part of the handle part is fixedly integrated with the reaming part 2 through a connecting section a4, the lower end of the reaming part 2 is fixedly integrated with the drill bit 3 through a connecting section B5, the diameter of the reaming part 2 is larger than that of the drill bit 3, the diameters of the connecting section a4 and the connecting section B5 are both smaller than that of the drill bit 3, and the vertex angle of the drill bit 3 is 85-95 degrees. In the structure, the connecting section A4 and the connecting section B5 mainly have the function of facilitating the sharpening of the cutter; the angle design of the drill top angle is matched with the characteristics of most of timbers, the more sharp the top angle is, the less the radial cutting resistance is during drilling, the less the vibration of the cutter is, and the angle can ensure the precision when reaming is not influenced.
The difference between the diameter of the reaming part 2 and the diameter of the drill bit 3 is less than or equal to 0.2 mm. The proper reaming amount is reserved after drilling, the machining precision can be influenced if the allowance is too large, and the surface quality can be influenced if the allowance is too small.
The vertex angle of the drill bit 3 is 90 degrees. This angle is a comparatively general angle, and applicable scope is wider.
The helix angle of the cutting edge of the reaming part 2 is 2-5 degrees. Because the vibration is small during wood processing, the precision can be ensured by the angle, and the discharge of wood chips is facilitated compared with the conventional straight teeth.
To sum up, the utility model provides a cutter accords with the wood working characteristic, can improve the efficiency of wooden pinhole processing by a wide margin.
The part of the utility model not detailed is prior art.
