Abstract
The utility model discloses a three-head type broaching boring cutter for a boring mill. The three-head type broaching boring cutter for the boring mill comprises a boring cutter fixing seat (1). The boring cutter fixing seat (1) is provided with a cutter head (2), the cutter head (2) is provided with three blades (3), and the three blades (3) are arranged in a central symmetry mode relative to the cutter head (2) and are cuboid. In addition, the blades (3) are inclined from the middle of the cutter head (2) towards the outer side, and are and arranged in an acute-angle mode. The three-head type broaching boring cutter for the boring mill has the advantages of being high in machining precision, long in service life, simple in structure and low in cost.
Description
Technical field
The utility model 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 that in actual applications the resistance that each blade of reaming boring cutter of two hair style structures is born is big, boring operation effort, directly influence the machining accuracy of operation, and the loss of blade is big, blade is short service life.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of machining accuracy height, 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 adopted in the utility model 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 described relatively 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 a side of adjacent two blades respectively, 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 utility model 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 drive 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 regulate the blade end position and realize accurate boring operation, 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 littler, the boring operation is more laborsaving, and the loss of blade is lower, has the machining accuracy height, long service life, simple in structure, advantage with low cost.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of the utility model embodiment.
Fig. 2 is the side-looking structural representation of the utility model embodiment.
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 preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
As depicted in figs. 1 and 2, the three hair style reaming boring cutters that 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.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 drive cutter head 2 is provided with 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 regulate blade 3 end positions and realize accurate boring operation, 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 littler, the boring operation is more laborsaving, and the loss of blade 3 is lower, has the machining accuracy height, 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 a side of adjacent two blades 3 respectively, and the both sides of any one blade 3 are equipped with reinforcing strip 41, and present embodiment is by reinforcing strip 41 clamping blades 3, make 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.
The above only is preferred embodiment of the present utility model, and protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.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 utility model, carrying out, these improvements and modifications also should be considered as protection domain of the present utility model.
