Abstract
The invention relates to the technical field of hardware cutters, and particularly relates to an arc-shaped milling cutter. The arc-shaped milling cutter provided by the invention comprises a handle and a tool bit base which are integrally arranged, and a tool bit connected on the tool bit base, wherein the tool bit is provided with a blade which comprises a concave arc-shaped blade in the middle and two convex arc-shaped blades respectively connected to both ends of the concave arc-shaped blade. The tool bit is further provided with an arc-shaped chip groove. The value range of radius R1 of the concave arc-shaped blade is 6-8mm, the value range of radius R2 of the convex arc-shaped blades is 1-3mm and the value range of radius of R3 of the arc-shaped chip groove is 10-13mm. The arc-shaped milling cutter provided by the invention is reasonable in structure and convenient to use. The concave arc-shaped blade is used to chamfer and process, so that the arc-shaped face is cut once to ensure the smoothness, thereby effectively improving the arc-shaped chamfering processing efficiency.
Description
Technical field
The present invention relates to hardware and cutting-tools technical field, particularly a kind of arc cutter.
Background technology
In the process of digital control processing, the sharp edge of some parts need to carry out chamfering, when chamfering workpiece is less and the radian of chamfering hour, can file and cultivate by pincers worker.But the radian of chamfering is excessive, the workload that pincers worker file is repaiied these positions is very large, and quality is also difficult for guaranteeing, by Digit Control Machine Tool, with arc cutter, is machined and can reach better effect.Therefore designing a kind of arc cutter rational in infrastructure, easy to use is extremely necessary.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, a kind of arc cutter rational in infrastructure, easy to use is provided.
For achieving the above object, the present invention is by the following technical solutions:
A kind of arc cutter of the present invention, comprise the handle of a knife and the cutter head pedestal that are wholely set, be connected in the cutter head on cutter head pedestal, wherein, on described cutter head, be provided with blade, described blade comprises the concave arc shape blade and two dome curved blades that are connected respectively described concave arc shape blade two ends of mid portion; On described cutter head, be also provided with a circular arc bits groove; Wherein, the span of the radius R 1 of described concave arc shape blade is 6 ~ 8mm, and the span of the radius R 2 of described dome curved blade is 1 ~ 3mm, and the span of the radius R 3 of described circular arc bits groove is 10 ~ 13mm.
Preferably, the radius R 1 of described concave arc shape blade is 8mm, and the radius R 2 of described dome curved blade is 2mm, and the radius R 3 of described circular arc bits groove is 12mm.
Preferably, the span of the diameter phi 1 of described cutter head is 20 ~ 25mm.
Preferably, the value of the diameter phi 1 of described cutter head is 25mm.
Preferably, described cutter head is connected on described cutter head pedestal by the mode of welding.
Beneficial effect of the present invention is: the present invention is rational in infrastructure, easy to use, adopts concave arc shape blade to carry out chamfer machining, and arc surface imposes uniformity without examining individual cases out, has guaranteed fineness, can effectively improve circular arc chamfering working (machining) efficiency; In addition, the two ends of concave arc shape blade are connected with respectively dome curved blade as transition, effectively processing work are protected; In addition, cutter head is connected on described cutter head pedestal by the mode of welding, has saved the cost of charp tool.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the arc cutter that provides of the embodiment of the present invention.
In figure: 1, handle of a knife; 2, cutter head pedestal; 3, cutter head; 4, blade;
401, concave arc shape blade; 402, dome curved blade; 5, chip area.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, a kind of arc cutter of the present invention, comprise the handle of a knife 1 and the cutter head pedestal 2 that are wholely set, be connected in the cutter head 3 on cutter head pedestal 2, wherein, on described cutter head 3, be provided with blade 4, described blade 4 comprises the concave arc shape blade 401 and two dome curved blades 402 that are connected respectively described concave arc shape blade 401 two ends of mid portion; On described cutter head 3, be also provided with a circular arc bits groove 5.In the present embodiment, the radius R 1 of described concave arc shape blade 401 is 8mm, and the radius R 2 of described dome curved blade 402 is 2mm, and the radius R 3 of described circular arc bits groove 5 is 12mm, and the value of the diameter phi 1 of described cutter head 3 is 25mm.Adopt concave arc shape blade to carry out chamfer machining, arc surface imposes uniformity without examining individual cases out, has guaranteed fineness, can effectively improve circular arc chamfering working (machining) efficiency; In addition, the two ends of concave arc shape blade are connected with respectively dome curved blade as transition, effectively processing work are protected.In the present embodiment, described cutter head 3 is connected on described cutter head pedestal 2 by the mode of welding, adopts the mode of welding, has saved the cost of charp tool.
In some other embodiment, it is 6 ~ 8mm that the span of the radius R 1 of described concave arc shape blade can be selected, it is 1 ~ 3mm that the span of the radius R 2 of described dome curved blade can be selected, it is 10 ~ 13mm that the span of the radius R 3 of described circular arc bits groove can be selected, and the span of the diameter phi 1 of described cutter head 3 is 20 ~ 25mm.In above number range, with reference to the dimensions of workpiece to be processed, can draw suitable parameter area, realize effect of the present invention.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
