Description
Technical field
The utility model relates to a kind of wood cutter, especially relates to a kind of combined drill and countersunk of processing wood panel counter sink.
Background technology
Along with growth in the living standard, people are more and more higher to the requirement of wood furniture, wooden building material, not only will meet use function, also require attractive and durable.When needs are processed counter sink in wood panel, current processing technology is that first hand drill bores an aperture, then bores counter sink, and then looks for the next position on plank to repeat above-mentioned drilling operation, yet hole like this, not only efficiency is low, and machining accuracy is not high, aperture is difficult for overlapping with the axis of heavy head bore, and the head of screw is likely heavy not to go down, profile is not attractive in appearance, be difficult to meet interchangeability requirement, working (machining) efficiency labour intensity low and workman is high, is not suitable for producing in enormous quantities.
Utility model content
The utility model aims to provide a kind of combined drill and countersunk of processing wood panel counter sink, and it is simple and reliable for structure, easy to use, and working (machining) efficiency is high, and machining accuracy is high, long service life, and the workpiece good looking appearance processing, shape and size precision is high, and interchangeability is good.
The utility model provides a kind of combined drill and countersunk of processing wood panel counter sink, comprises bore portion and reamer; Described reamer has penetrating centre bore, and reamer comprises the reamer blade of leading portion and the reamer shank of back segment, and reamer blade comprises that one section is positioned at the oblique linear blade I in its end and is positioned at its surperficial spirality chip area; Bore portion is fixed in reamer centre bore and its front end termination is positioned at reamer blade outside.
Preferably, described bore portion is fluted drill.
Preferably, described reamer blade lateral surface has one section of linear blade II parallel with axis, and linear blade II termination is connected with linear blade I termination.
Preferably, described reamer has radial direction through hole, and pin or screw can be fastenedly connected reamer and bore portion by radial direction through hole.
The utility model not only machining accuracy is high, and working (machining) efficiency is high, simple in structure, safe and reliable, long service life, the workpiece good looking appearance processing.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is for being used the generalized section of the rear workpiece of the utility model processing;
In figure: 1-bore portion, 11-bore portion blade, 12-bore portion shank, 2-reamer, 21-reamer blade, 22-reamer shank, 23-linear blade I, 24-linear blade II, 25-chip area, 26-through hole.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model discloses a kind of combined drill and countersunk of processing wood panel counter sink, comprise bore portion 1 and reamer 2; Described reamer 2 has penetrating centre bore, and reamer comprises the reamer blade 21 of leading portion and the reamer shank 22 of back segment, and reamer blade 21 comprises that one section is positioned at the oblique linear blade I23 in its end and is positioned at its surperficial spirality chip area 25; Bore portion 1 comprises the bore portion blade 11 of leading portion and the bore portion shank 12 of back segment, and bore portion 1 is fixed in reamer 2 centre bores, and bore portion blade 11 front ends are positioned at reamer blade 21 outsides.
Preferably, bore portion 1 is fluted drill.
Preferably, reamer blade 21 lateral surfaces have one section of linear blade II24 parallel with axis, linear blade II24 termination is connected with linear blade I23 termination, and described linear blade I23 is outward-dipping to linear blade II24 by reamer blade 21 terminations.
Preferably, reamer 2 has radial direction through hole 26, and pin or screw can be fastenedly connected reamer 2 and bore portion 1 by radial direction through hole.During concrete use, lead to the hole site can be arranged on to reamer shank 22, in the relevant position of bore portion shank 12, the radial hole suitable with radial direction through hole 26 is set, this radial hole can be through hole simultaneously, then by pin or screw, reamer 2 and bore portion 1 is fastenedly connected.
Figure 2 shows that the Workpiece structure schematic diagram that uses the utility model to process, find in use the position that needs processing accurately, only need once hole and can process counter sink as shown in Figure 2, process easy, machining accuracy is high, safe and reliable, and the workpiece size precision processing is high, interchangeability is good, good looking appearance.
Certainly; the utility model also can have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
