Abstract
The utility model relates to a double-edge thread chasing tool with a symmetrical oblique shaft, which comprises a cutter blade with a quadrangular cross section; cutting edges with the same tooth shape and the same number of the teeth, which are symmetrically distributed along a quadrangular oblique shaft are arranged on two adjacent sides of the cutting ends of the cutter blade. The utility model can improve the utilization rate of cutter materials, and besides, cutting edges which are not used for cutting are far away from work pieces and are not easy to be wound by iron dust in manufacturing process; the utility model has the advantages of good protection, convenient installation and convenient use; the utility model is suitable for processing left hand threads, right-hand threads, internal threads and external threads.
Description
The utility model relates to a kind of chaser, particularly a kind of inclined shaft symmetry twolip chaser.
In the prior art, commonly used is the single-blade chaser, has only a side that cutting edge is arranged on the blade, and then the utilization rate to cutter material is lower.The tight chaser of TMAX series twin-lock is disclosed in Sweden's Sandvik (SANDVIK) company cutter sample, the symmetrical twolip chaser of a kind of axis is wherein arranged, improved the utilization rate of cutter material, but that in its installation, when dismounting, need is fastening, unclamp two fixed screws, uses inconvenient; And two cutting edges are all in the same direction that contacts with workpiece, and the iron filings that the blade that does not participate in cutting is cut generation easily twine and cause and forge a knife.
The purpose of this utility model is to provide a kind of improved twolip chaser, can improve the utilization rate of cutter material, and the blade that does not participate in cutting in again can process is difficult for away from workpiece being twined by iron filings, and easy for installation.
For achieving the above object, the utility model adopts following technical proposals: this is practical, and the same with prior art to include a cross section be tetragonal blade.Be characterized in: there is the identical cutting edge identical with the number of teeth of profile of tooth that is symmetrically distributed along the quadrangle inclined shaft the two adjacent sides, cutting end of blade.
The utility model has following conspicuous advantage compared with prior art: the utility model has two cutting edges, still can improve the cutter material utilization rate; A cutting edge adds man-hour, and another cutting edge is difficult for running into iron filings and is subjected to good protection on 90 degree directions of symmetry; Installation can be adopted the pressure type mechanical clamp, simplifies and installs, and reduces tool change time, and is easy to use.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the end view of the blade cut end of an embodiment of the utility model.
Fig. 2 is the profile that the A-A place dwindles among Fig. 1.
An optimum implementation of the present utility model: referring to Fig. 1 and Fig. 2, it is tetragonal blade 6 that this inclined shaft symmetry twolip chaser includes a cross section, and there is the identical cutting edge identical with the number of teeth 1,5 of profile of tooth that is symmetrically distributed along quadrangle inclined shaft 3 the two adjacent sides, cutting end of blade 6.Distance between each cutting edge side, 1 place and the opposite flank 4 equals the distance between another cutting edge side, 5 place and the opposite flank.The opposite flank 4,2 of each cutting edge 1,5 is its radial location face, and the side 2,4 of adjacent no cutting edge is its axial locating surface.The locating surface 2,4 of two no cutting edges is vertical mutually.Each cutting edge 1,5 can have one or several cutters tooth.Each cutting edge 1,5 has 3 cutters tooth shown in this routine accompanying drawing.Cutting edge 1,5 button shapes can be decided with screw-thread form, then applicable to the processing of left hand thread and right-handed thread, internal and external threads.
Claims (5)
