Description
Technical field
The present invention relates to a kind of three hair style reaming boring cutters for boring machine.
Background technology
The reaming boring cutter that is used for boring machine of prior art is two hair style structures, but finds in actual applications, and the resistance that each blade of reaming boring cutter of two hair style structures is born is large, boring operation effort, directly affect the machining accuracy of operation, and the loss of blade is large, blade is short service life.
Summary of the invention
The technical problem to be solved in the present invention provides that a kind of machining accuracy is high, long service life, three hair style reaming boring cutters that are used for boring machine simple in structure, with low cost.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of three hair style reaming boring cutters for boring machine, comprise the boring cutter holder, described boring cutter holder is provided with cutter head, described cutter head is provided with three blades, the relatively described cutter head of described three blades layout that is centrosymmetric, described blade is rectangular-shaped, and described blade from the middle part of cutter head the outward-dipping acute angle that is arrange.
As further improvement in the technical proposal:
Described cutter head is provided with three blade gusset plates, described blade gusset plate comprises two integral structures and is the reinforcing strip that 120 degree angles are arranged, described reinforcing strip is in abutting connection with described blade arrangement, two reinforcing strip of a described blade gusset plate are fixed respectively a side of adjacent two blades, and the both sides of any one blade are equipped with reinforcing strip.
Described cutter head is provided with three connectors, and described connector is located between two reinforcing strip of described blade gusset plate, and described cutter head links to each other with the boring cutter holder by three connectors.
The present invention is installed in the boring cutter holder on the boring machine in use, open boring machine operation button, then the drive system of boring machine will drive the rotation of boring cutter holder, three blade rotation that boring cutter holder band dynamic cutter head is provided with are carried out the boring operation, because blade is the outward-dipping acute angle layout that is from the middle part of cutter head, can realize accurate boring operation by the adjustable blade end position, and because cutter head is provided with three blades, the form of relative two blades of prior art, the resistance that each blade is born is less, the boring operation is more laborsaving, and the loss of blade is lower, has machining accuracy high, long service life, simple in structure, advantage with low cost.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective view of the embodiment of the invention.
Fig. 2 is the side-looking structural representation of the embodiment of the invention.
Marginal data: 1, boring cutter holder; 2, cutter head; 21, connector; 3, blade; 4, blade gusset plate; 41, reinforcing strip.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention are made more explicit defining.
As depicted in figs. 1 and 2, the three hair style reaming boring cutters that the present embodiment is used for boring machine comprise boring cutter holder 1, boring cutter holder 1 is provided with cutter head 2, cutter head 2 is provided with three blades 3, three blade 3 relative cutter heads 2 layout that is centrosymmetric, blade 3 is rectangular-shaped, and blade 3 from the middle part of cutter head 2 the outward-dipping acute angle that is arrange.The present embodiment in use, boring cutter holder 1 is installed on the boring machine, open boring machine operation button, then the drive system of boring machine will drive 1 rotation of boring cutter holder, three blades 3 that boring cutter holder 1 is provided with dynamic cutter head 2 rotate and carry out the boring operation, because blade 3 is the outward-dipping acute angle layout that is from the middle part of cutter head 2, can realize accurate boring operation by adjustable blade 3 end positions, and because cutter head 2 is provided with three blades 3, the form of relative two blades 3 of prior art, the resistance that each blade is born is less, the boring operation is more laborsaving, and the loss of blade 3 is lower, has machining accuracy high, long service life, simple in structure, advantage with low cost.
In the present embodiment, cutter head 2 is provided with three blade gusset plates 4, blade gusset plate 4 comprises two integral structures and is the reinforcing strip 41 that 120 degree angles are arranged, reinforcing strip 41 is arranged in abutting connection with blade 3, two reinforcing strip 41 of a blade gusset plate 4 are fixed respectively a side of adjacent two blades 3, and the both sides of any one blade 3 are equipped with reinforcing strip 41, and the present embodiment is by reinforcing strip 41 clamping blades 3, so that the intensity of blade 3 is better, longer service life.
In the present embodiment, cutter head 2 is provided with three connectors 21, connector 21 is located between two reinforcing strip 41 of blade gusset plate 4, cutter head 2 links to each other with boring cutter holder 1 by three connectors 21, the structure that connector 21 is located between two reinforcing strip 41 of blade gusset plate 4 can effectively avoid connector 21 to contact long service life with workpiece in the boring cutter use procedure.
The above only is preferred embodiment of the present invention, and protection scope of the present invention is not limited in above-mentioned embodiment, and every technical scheme that belongs to the principle of the invention all belongs to protection scope of the present invention.For a person skilled in the art, some improvements and modifications of under the prerequisite that does not break away from principle of the present invention, carrying out, these improvements and modifications also should be considered as protection scope of the present invention.
