Abstract
The invention relates to a double-edge internal thread milling cutter which is of an integral structure and comprises a cylindrical cutter handle (1); the front end of the cutter handle is connected with a transition guide rod (2) with an inner concave arc surface; the front end of the transition guide rod (2) is connected with a cylindrical cutter arbor (3); the side surface of the front end of the cutter arbor (3) is provided with two protruded cutting edges (4) which are arranged opposite to each other; the tip angles of the cutting edges are 60 degrees; and two chip containing grooves (5) are milled on the front part of the cutter arbor along the front cutter surfaces of the cutting edges. The double-edge internal thread milling cutter is provided with two protruded cutting edges, a certain space is left between the cutter arbor and the inner wall of a hole, two larger chip containing grooves are arranged, so that the discharge of chips is convenient, and the processing efficiency is high.
Description
Technical field
The present invention relates to a kind of screw tool, particularly a kind of internal thread milling cutter.
Background technology
Common screw cutter is whole hard alloy screw cutter and frame blade type screw cutter, has 5-7 serrated knife point screw thread, can process at one time screw thread.The general work flow of multiple tooth screw cutter is; Be covered with screw thread processing tooth on the cutting edge of screw cutter; Three-shaft linkage through Digit Control Machine Tool; Utilize formed threading tool to carry out the spiral interpolation and form screw thread, cutter is processed along helix can accomplish screw thread processing a week, also can rotate more and reach the screw thread requirement degree of depth several weeks.Its shortcoming is that it is many that multiple tooth screw cutter takies processing space, and chip removal has some setbacks, and causes the wearing and tearing of cutter easily, reduces the service life of cutter, has also reduced the efficient of cutter machining screw simultaneously.
Summary of the invention
In order to overcome above-mentioned technological deficiency, the object of the present invention is to provide the internal thread milling cutter that a kind of chip space is big and working (machining) efficiency is high.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of twolip internal thread milling cutter; The structure that is formed in one, it comprises a cylindrical knife shank, said handle of a knife front end be connected with one have an inner concave arc surface the transition guide rod; Transition guide rod front end is connected with a cylinder shape knife rod; Be extruded with two cutting edges that are oppositely arranged on the said knife bar front end side, the blade tip angle of said cutting edge is 60 °, and the knife bar front portion is milled with two chip pockets along the cutting edge rake face.
Beneficial effect of the present invention is, it has two outstanding cutting edges, and knife bar and hole inwall leave certain space, and it has two bigger chip pockets, and chip removal is convenient, the working (machining) efficiency height.
Description of drawings
Fig. 1 is the structure chart of twolip internal thread milling cutter of the present invention;
Fig. 2 is the partial enlarged drawing at twolip internal thread milling cutter cutting edge of the present invention place.
The specific embodiment
By Fig. 1, shown in Figure 2:
The twolip internal thread milling cutter of present embodiment; The structure that is formed in one, it comprises a cylindrical knife shank 1, said handle of a knife front end be connected with one have an inner concave arc surface transition guide rod 2; Transition guide rod 2 front ends are connected with a cylinder shape knife rod 3; Be extruded with two cutting edges 4 that are oppositely arranged on the said knife bar 3 front end sides, the blade tip angle of said cutting edge is 60 °, and the knife bar front portion is milled with two chip pockets 5 along the cutting edge rake face.
The twolip internal thread milling cutter of present embodiment has two outstanding cutting edges, and knife bar and hole inwall leave certain space, and it has two bigger chip pockets, and chip removal is convenient, the working (machining) efficiency height.
