Abstract
The invention provides a thread milling cutter with multiple teeth. The thread milling cutter with the multiple teeth comprises a cutting head, a hilt and an arbor. The cutting head is used for cutting workpieces, an operator can hold the thread milling cutter via the hilt, the hilt is connected with the cutting head by the arbor, the diameter of the arbor is smaller than the diameter of the cutting head and the diameter of the hilt, a plurality of cutting sections are arranged on the cutting head, a plurality of cutting teeth are arranged on the cutting sections, and the various cutting sections are structurally identical. The thread milling cutter with the multiple teeth has the advantages that the thread milling cutter with the multiple teeth can machine threads of deep inner holes owing to the hilt, and the service range of the thread milling cutter is expanded; the thread machining efficiency is effectively improved when the thread milling cutter with the various cutting teeth is used for machining the threads, and the thread milling cutter is suitable for machining and manufacturing internal threads on a large scale.
Description
Technical field
The present invention relates to the cutter field of machining, particularly a kind of polydonita screw cutter.
Background technology
Traditional internal thread machining mainly adopts screw tap to carry out the manual or motor-driven screw thread processed of attacking; because its cutting contact-making surface is bigger; cutting force is bigger; screw tap fractures easily; and internal thread machining is as last procedure of processing; what screw tap had broken part that regular meeting causes scraps the manpower that causes and cost waste.Along with the generation of raising, three-shaft linkage or the multi-axis linkage numerical control system of the innovation of development of numerical control (NC) technology, software, control accuracy and in the extensive use of production field, corresponding advanced processing technology---thread milling is achieved gradually, and its machining accuracy, fineness and flexibility are that tapping is incomparable.
Summary of the invention
In order to solve the problem that tradition exists, to the invention provides following technical scheme be:
A kind of polydonita screw cutter, described polydonita screw cutter, comprise the cutting head that workpiece is cut, the handle of a knife that is used for clamping, also comprise the knife bar that connects handle of a knife and cutting head, the diameter of described knife bar is less than the diameter of cutting head and handle of a knife, and described cutting head is provided with a plurality of segment of cutting, described segment of cutting is provided with a plurality of cutting teeths, and the structure of each segment of cutting is identical.
Further, the angle between the described cutting teeth is 60 °, and this milling cutter is used for the milling cutter of processing regular screw threads.
The beneficial effect that the present invention brings is:
The handle of a knife of the present invention by arranging, make the polydonita screw cutter can the darker inner hole thread of machining hole, enlarged the scope of application of screw cutter, polydonita screw cutter of the present invention, have a plurality of cutting teeths, adding the processing speed that effectively raises screw thread man-hour, be applicable in the large batch of internal thread machining production.
Description of drawings
Fig. 1 is structural representation of the present invention.
Number in the figure is:
1-cutting head, 2-knife bar, 3-handle of a knife, 4-segment of cutting, 5-cutting teeth.
The specific embodiment
Below to by reference to the accompanying drawings preferred embodiment of the present invention being elaborated, 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 is made more explicit defining.
As shown in Figure 1, a kind of polydonita screw cutter, described polydonita screw cutter, comprise the cutting head 1 that workpiece is cut, the handle of a knife 3 that is used for clamping, also comprise the knife bar 2 that connects handle of a knife and cutting head, the diameter of described knife bar 2 is less than the diameter of cutting head 1 and handle of a knife 3, described cutting head 1 is provided with a plurality of segment of cutting 4, described segment of cutting 4 is provided with a plurality of cutting teeths 5, and the structure of each segment of cutting 4 is identical, and the angle between the described cutting teeth 5 is 60 °, the described polydonita screw cutter of present embodiment is mainly used in processing regular screw threads, and we can also process the screw thread of different rotation directions by the motion of control machining tool.
Polydonita screw cutter of the present invention can be used for the bigger inner hole thread of processing hole depth, and knife bar can not contact with the surface of workpiece, guaranteed the crudy of workpiece, a plurality of segment of cutting of setting can be conducive to improve the speed of internal thread machining, have improved production efficiency.
The above; it only is one of the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
Claims (2)
1. polydonita screw cutter, it is characterized in that, described polydonita screw cutter, comprise the cutting head that workpiece is cut, be used for the handle of a knife of clamping, also comprise the knife bar that connects handle of a knife and cutting head, the diameter of described knife bar is less than the diameter of cutting head and handle of a knife, described cutting head is provided with a plurality of segment of cutting, and described segment of cutting is provided with a plurality of cutting teeths, and the structure of each segment of cutting is identical.
2. a kind of polydonita screw cutter according to claim 1 is characterized in that, the angle between the described cutting teeth is 60 °.
