Abstract
The invention provides a novel multi-teeth thread milling cutter which is characterized by comprising a cutting head used for cutting a workpiece, and a tool shank used for clamping, as well as a cutter arbor used for connecting the former two, wherein the diameter of the cutter arbor is smaller than that of the cutting head and the tool shank; a plurality of cutting sections in the same structure are arranged on two edges of the cutting head, and a plurality of cutting teeth are arranged on the cutting sections; tool nose heads are arranged on the cutting teeth; a tool shank bottom is also arranged on the tool shank; and the middle part of the tool shank is concave. According to the invention, with the tool shank, the milling cutter can be easily held, so as to facilitate the processing of screws for deeper inner holes, and accordingly, the thread milling cutter is widened in application range. The milling cutter with the plurality of cutting teeth can effectively improve the thread processing efficiency during processing, and therefore is suitable for processing and production of mass internal threads.
Description
Technical field
The present invention relates to the cutter field of machining, particularly a kind of novel 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 larger; cutting force is larger; screw tap easily fractures; and internal thread machining is as last procedure of processing; what screw tap had broken the part that often can cause scraps the manpower that causes and the waste of cost.Along with the generation of raising, three-shaft linkage or the multi-axis linkage numerical control system of the innovation of the development of Numeric Control Technology, software, control accuracy and in the extensive use of production field, corresponding Advanced: 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 of tradition existence, to the invention provides following technical scheme be:
A kind of novel polydonita screw cutter, it is characterized in that, described novel 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, described cutting head both sides all are provided with a plurality of segment of cutting, be provided with a plurality of cutting teeths on the described segment of cutting, and the structure of each segment of cutting is identical, is provided with the point of a knife head on the described cutting teeth, also be provided with the handle of a knife bottom on the described handle of a knife, described handle of a knife centre position is spill.
Further, the angle between the described cutting teeth is 60 °.
Further, the angle between the described point of a knife head is 90 °, 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, can be easy to be held in the hand use, more can the darker endoporus screw of machining hole, enlarged the screw cutter scope of application, novel polydonita screw cutter of the present invention, have a plurality of cutting teeths, adding the working (machining) efficiency that effectively raises screw thread man-hour, be applicable to large batch of internal thread machining and produce.
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, 6-point of a knife head, 7-handle of a knife bottom.
The specific embodiment
The below is to elaborating preferred embodiment of the present invention by reference to the accompanying drawings, 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 made more explicit defining.
As shown in Figure 1, a kind of novel polydonita screw cutter, described novel 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 3 and cutting head 1, the diameter of described knife bar 2 is less than the diameter of cutting head 1 and handle of a knife 3, and described cutting head 1 both sides all are provided with a plurality of segment of cutting 4, is provided with a plurality of cutting teeths 5 on the described segment of cutting 4, and the structure of each segment of cutting 4 is identical, be provided with point of a knife head 6 on the described cutting teeth 5, also be provided with handle of a knife bottom 7 on the described handle of a knife 3, described handle of a knife 3 centre positions are spill, angle between the described cutting teeth 5 is 60 °, and the angle between the described point of a knife head 6 is 90 °.The described novel polydonita screw cutter of the present embodiment is mainly used in processing regular screw threads, and we can also process by the motion of controlled working lathe the screw thread of different rotation directions.
In sum, the handle of a knife of the present invention by arranging, can be easy to be held in the hand use, more can the darker endoporus screw of machining hole, enlarged the screw cutter scope of application, novel polydonita screw cutter of the present invention has a plurality of cutting teeths, adding the working (machining) efficiency that effectively raises screw thread man-hour, be applicable to large batch of internal thread machining and produce.
The above; it only is one of the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; 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.
