Abstract

The utility model relates to a multi-tip thread cutter, one end part of which is provided with at least two cutter tips, wherein the lengths of the cutter tips are lengthened gradually from one end to the other end; and the interval between two adjacent cutter tips is identical with the pitch. The advantages are as follows: the multi-bit thread cutter has small cutting stress, high processing precision, and reliability and stability in processing when being used for cutting threads; simultaneously, the service life of the cutter can be prolonged and the consumption of productive resources is lowered; and compared with the common thread cutter, the multi-tip thread cutter can greatly improve processing efficiency and lower processing cost.

Description

The multiple thread lathe tool
Technical field
The utility model belongs to field of machining, particularly relates to a kind of multiple thread lathe tool.
Background technology
Screw thread is meant on cylinder or conical surface along the formed geometry with regulation tooth form of helix continuous motion.In screw thread processing, feed speed must be accurately corresponding with the pitch of screw thread.But the stress that the turning stress of screw thread is born than common cutting feeding is high a lot, and the cutting end part radius of screw thread blade is less, and is relatively weaker.So in screw thread processing, often occur disorderly detaining or collapse problem such as cutter, so not only reduce production efficiency, and strengthened production cost.
Summary of the invention
The utility model provides a kind of multiple thread lathe tool for solving the technical problem that exists in the known technology, and cutting stress was little when it was used for cutted thread, and the machining accuracy height is processed reliable and stable.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of multiple thread lathe tool, comprise cutter hub, and it is characterized in that: the end of cutter hub is provided with at least two points of a knife, and the length of point of a knife increases gradually from an end to the other end.
Spacing and pitch between the described point of a knife match.
A number of the quantity of described point of a knife and screw thread matches.
The shape of described point of a knife and the tooth form of screw thread match.
Advantage and the good effect that the utlity model has are: after the utility model has adopted above technical scheme, the rotation of part main shaft in the process of processing adds that the stress that feed motion produced of screwer is born by two screw thread points of a knife, cutter life can be improved greatly, and the resource consumption of producing is minimized.The multiple thread lathe tool is clearly on machining accuracy simultaneously, because most cutting stress is shared jointly by two points of a knife, the part vibration that is produced also can reduce, part precision is guaranteed.The multiple thread lathe tool is compared with common threading tool simultaneously, can increase substantially working (machining) efficiency, reduces process time, cuts down finished cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is user mode figure of the present utility model.
Among the figure: 1, multiple thread lathe tool; 1-1, cutter hub; 1-2, point of a knife; 2, workpiece to be machined.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, now exemplify following examples, and conjunction with figs. is described in detail as follows: see also Fig. 1, a kind of multiple thread lathe tool 1 comprises cutter hub 1-1, and the end of multiple thread lathe tool 1 is provided with at least two point of a knife 1-2, the length of point of a knife increases gradually from an end to the other end, spacing and pitch between the point of a knife match, and a number of the quantity of point of a knife and screw thread matches, and the shape of point of a knife and the tooth form of screw thread match.
Operating principle of the present utility model is: see also Fig. 2, have a series of points of a knife on the multiple thread lathe tool 1 continuously, the degree of depth of any point of a knife in thread groove is all darker than a point of a knife of its front.By these points of a knife 1-2, the multiple thread lathe tool can be processed a plurality of thread grooves simultaneously to workpiece to be machined 2, and the operation road number of screw thread can reduce significantly.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
