Description
Technical Field
The utility model relates to a cutter technique, the cutter that especially carpenter used specifically is a dedicated dovetail milling cutter of carpenter.
Background
The dovetail groove is similar to a T-shaped groove and is a common connecting structure in machining, a through groove is machined on a metal material, and then the dovetail groove is machined at the bottom of two side walls of the through groove by using a single dovetail groove milling cutter.
At present, the process is still used when dovetail grooves are processed on a wooden product; the above process obviously has the problems of excessive working procedures and low efficiency in consideration of the easy cutting property of wood.
Disclosure of Invention
To the problem in the background art, the utility model aims at providing a dedicated dovetail milling cutter of carpenter, through the structure of design combination formula, when processing the dovetail on timber, can once process out whole shapes of whole dovetail, the forked tail part of cutter is removable, has higher commonality, in addition, the sharpening of the cutter of also being convenient for.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a dovetail milling cutter special for woodworker comprises a straight shank end milling cutter, a dovetail cutter and a locking screw, wherein the straight shank end milling cutter consists of a cutter handle, a circumferential cutting part positioned at the lower end of the cutter handle and a fixed shaft positioned at the lower end of the circumferential cutting part, the diameter of the fixed shaft is smaller than the cutting diameter of the circumferential cutting part, and a threaded hole with an opening at the lower part is formed at the lower end of the fixed shaft; the whole dovetail cutter is of a cone frustum structure, an axial through hole is formed in the middle of the dovetail cutter, the axial through hole is matched with the fixed shaft, and the dovetail cutter is sleeved on the fixed shaft of the straight shank end milling cutter and fixedly connected with the straight shank end milling cutter through a locking screw.
And a key groove is also arranged in the axial through hole of the dovetail cutter, and a flat key is arranged in the key groove and is connected with the fixed shaft of the straight shank end milling cutter through the flat key.
The edge inclination angle of the bottom cutting edge of the dovetail knife is larger than 7 degrees.
The utility model has the advantages that: the utility model discloses simple structure, firm, can once only process out the forked tail cell type on timber, in the cutter, the forked tail sword part of easily damaging is removable, and not fragile end mill part repetitious usage, and the coping of the cutter of also being convenient for of such structure simultaneously, the long service life of cutter has certain economic benefits.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
FIG. 2 is a schematic view of a dovetail knife.
FIG. 3 is a bottom view of the dovetail knife.
FIG. 4 is a schematic edge rake angle of a dovetail bottom cutting edge in one embodiment.
In the figure, the tool comprises a tool shank 1, a tool shank 2, a circumferential cutting part 3, a fixed shaft 4, a dovetail knife 5, a locking screw 6, an axial through hole 7, a key groove 8 and a flat key.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, the dovetail milling cutter special for carpenters comprises a straight shank end mill, a dovetail cutter 4 and a locking screw 5, wherein the straight shank end mill comprises a cutter handle 1, a circumferential cutting part 2 positioned at the lower end of the cutter handle 1 and a fixed shaft 3 positioned at the lower end of the circumferential cutting part 2, the diameter of the fixed shaft 3 is smaller than that of the circumferential cutting part 2, and a threaded hole with an opening at the lower part is formed at the lower end of the fixed shaft 3; the whole dovetail cutter 4 is of a cone frustum structure, an axial through hole 6 is formed in the middle of the dovetail cutter, the axial through hole 6 is matched with the fixed shaft 3, and the dovetail cutter 4 is sleeved on the fixed shaft 3 of the straight shank end milling cutter and fixedly connected with the straight shank end milling cutter through a locking screw 5.
The dovetail cutter 4 is further provided with a key groove 7 in the axial through hole 6, and a flat key 8 is arranged in the key groove 7 and connected with the fixed shaft 3 of the straight shank end mill through the flat key 8. Correspondingly, a groove matched with the flat key 8 is also arranged on the outer cylindrical surface of the fixed shaft 3 of the straight shank end mill. For the dovetail milling cutter with larger diameter, the key connection is adopted to ensure that the structure of the cutter is more stable, and the cost of the key connection is the lowest.
The edge inclination angle of the bottom cutting edge of the dovetail knife 4 is more than 7 degrees. Its bottom cutting edge of dovetail that cuts metal material generally is within 7 degrees, because cutting timber, when increase bottom sword inclination, can make the cutter sharper, increases bottom space simultaneously, the chip removal and the heat dissipation of being convenient for in an embodiment of the utility model, as shown in fig. 4, the sword inclination of bottom cutting edge is 14 degrees.
The part of the utility model not detailed is prior art.
