Technical field

The utility model is related to a kind of screw cutter, specially a kind of two-sided screw cutter with taper shank belongs to machinery Processing equipment field.

Background technology

In mechanical processing process, common machining tool is typically milling cutter, the effect during the work pieces process of milling cutter Very big, milling cutter can mill out the end face of workpiece, and milling cutter can be mounted on machining tool with the profile of workpiece at milling, existing milling cutter When above, fixed form be easy to cause milling cutter and fixes shakiness, the phenomenon that flail knife, and milling cutter processing in this way occurs Workpiece surface roughness out is larger, and the quality of workpiece cannot be guaranteed, and existing milling cutter is needed in milling thread Thread Pilot hole first is processed with drill bit, then uses milling cutter thread milling again, this processing method process dispersion is needed frequently to replace and be bored Head and milling cutter, and in order to enable drill bit and milling cutter can be coaxial, so to be debugged during milling cutter thread milling, so as to cause life It is low to produce efficiency, existing milling cutter is due to being unable to self-control length, so when contacting workpiece easily by milling machine and workpiece Bidirectional-squeezing is so that the phenomenon that tipping easily occurs for the blade of milling cutter.

Utility model content

The purpose of this utility model is that solve the above-mentioned problems and provides a kind of two-sided thread milling machine with taper shank Knife.

The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of two-sided screw cutter with taper shank, Including fixed link, cutter head, milling edge, chip space, screwer, motion bar, spring and handle of a knife；The fixed link lower end is fixed with knife Head, the motion bar are engaged on inside fixed link, and the motion bar can move up and down inside fixed link, are set on the motion bar It is equipped with spring, one end of the spring is fixed on motion bar top and the other end is fixed on fixed link upper end, on the motion bar Handle of a knife is fixed with, the handle of a knife is made of for taper and its surface coated with cutter head described in wear-resistant coating milling edge and chip space, The milling edge is two-sided blade, and simultaneously spiral is distributed upwards for time distribution between the milling edge and chip space, the cutter head bottom Symmetrical two screwers are fixed with, the milling edge and screwer share chip space.

Further, in order to once mill out bottom outlet and screw thread, the cutter head bottom is fixed with symmetrical two spiral shells Line knife.

Further, in order to prevent milling bottom outlet when the accumulation of debris that generates at screwer, the milling edge and screw thread Knife shares chip space.

Further, in order to strengthen the intensity of milling cutter, the milling edge is two-sided blade.

Further, in order to enable cutter head can move up and down so that cutter head can be close to workpiece, the motion bar It can be moved up and down inside fixed link.

Further, in order to enable milling cutter can be connected on clamping device rapidly, the handle of a knife is taper and its surface Coated with wear-resistant coating.

The beneficial effects of the utility model are：The two-sided screw cutter structure connects compact, reasonable design, and cutter head bottom is consolidated Surely there are symmetrical two screwers, can once mill out bottom outlet and screw thread, first mill out thread Pilot hole with milling edge, with milling Sword gos deep into, and bottom outlet is milled out screw thread by screwer, without tool changing in whole process, so as to reduce tool changing, dress knife and tune Knife time, milling edge and screwer share chip space, and the accumulation of debris for preventing from generating during milling bottom outlet ensures milling at screwer The thread quality cut out, milling edge are two-sided blade, and the setting of double-sided blade strengthens the intensity of milling cutter, and the anti-of cutter collapses scarce energy Power is strong, makes that its chip process is steady, and motion bar can move up and down inside fixed link, and have bullet between motion bar and fixed link Spring support so that cutter head can move up and down so that cutter head can be close to workpiece, can significantly improve workpiece surface finish and Dimensional accuracy, but also the Bidirectional-squeezing power of milling machine that two-sided screw cutter is subject to and workpiece can be reduced, handle of a knife for taper and Its surface is coated with wear-resistant coating, and the handle of a knife of taper enables milling cutter to be connected on clamping device rapidly, easy to disassemble.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained shall fall within the protection scope of the present invention.

- 2 are please referred to Fig.1, a kind of two-sided screw cutter with taper shank, including fixed link 1, cutter head 2, milling edge 3, chip removal Slot 4, screwer 5, motion bar 6, spring 7 and handle of a knife 8；1 lower end of fixed link is fixed with cutter head 2, and the motion bar 6 is engaged on Inside fixed link 1, the motion bar 6 can move up and down inside fixed link 1, and spring 7 is provided on the motion bar 6, described One end of spring 7 is fixed on 6 top of motion bar and the other end is fixed on 1 upper end of fixed link, and handle of a knife is fixed on the motion bar 6 8, the handle of a knife 8 is made of for taper and its surface coated with cutter head 2 described in wear-resistant coating milling edge 3 and chip space 4, the milling Sword 3 is cut as two-sided blade, simultaneously spiral is distributed upwards for time distribution between the milling edge 3 and chip space 4, and 2 bottom of cutter head is consolidated Surely there are symmetrical two screwers 5, the milling edge 3 and screwer 5 share chip space 4.

A kind of technical optimization scheme as the utility model：2 bottom of cutter head is fixed with symmetrical two screwers 5；The milling edge 3 and screwer 5 share chip space 4；The milling edge 3 is two-sided blade；The motion bar 6 can be in fixation It is moved up and down inside bar 1；The handle of a knife 8 is coated with wear-resistant coating for taper and its surface.
