the milling cutter piece comprises a fixing portion matched with the milling cutter piece mounting groove in size, a cutting edge is arranged in front of the top of the fixing portion, a through hole is formed in the middle of the fixing portion, and the milling cutter piece is fixed on the fixing base after penetrating through the through hole and being in threaded connection with the screw fixing hole through a locking screw.
Furthermore, the thickness of the fixing seat is larger than that of the cutter head, and the cross sections of the fixing seat and the cutter head are located on the same plane.
Furthermore, the upper part of the fixed seat is provided with a chip removing groove along the circumferential direction of the cutter head.
Furthermore, a cutter mounting hole is formed in the middle of the cutter head.
Furthermore, a cutter positioning hole is further formed in one side, located on the cutter mounting hole, of the cutter disc.
The utility model has the advantages that;
the milling cutter comprises a cutter head, two or four milling cutter blade fixing seats, a milling cutter mounting surface is arranged on each fixing seat, Y-shaped milling cutter blade mounting grooves are concavely arranged on the mounting surfaces, the milling cutter blades are not prone to left-right swinging during cutting after being fixed through the Y-shaped milling cutter blade mounting grooves, and the precision of a square groove cut is improved.
Secondly, through setting up fixing base thickness and being greater than blade disc thickness, can effectual improvement milling cutter piece, the stress surface when cutting avoids milling cutter piece rupture when cutting.
Thirdly, through setting up the chip groove, can make the piece when copper pipe fitting mills the square groove break away from the cutting edge fast.
And fourthly, the whole clamping of the cutter is facilitated by arranging the cutter mounting hole.
And fifthly, by arranging the cutter positioning hole, when the rotary cutter is used, the cutter mounting hole and the cutter positioning hole are jointly fixed, so that the cutter is more stable to rotate.
Drawings
Fig. 1 is a schematic view of four fixed tool holders according to the present invention.
Fig. 2 is a schematic view of cutting a square groove.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
The present embodiment provides a tool for milling a square groove, as shown in figure 1,
a cutter head 10 and a milling cutter blade 20 fixedly connected to the cutter head 10;
two or four milling blade fixing seats 101 are uniformly distributed and fixedly connected on the cutter head 10 along the outer circumferential direction thereof, the front of each fixing seat 101 is provided with a milling blade mounting surface 1011, a Y-shaped milling blade mounting groove 1012 is concavely arranged on the milling blade mounting surface 1011, and the middle part of each milling blade mounting groove 1012 is provided with a screw fixing hole 1013;
the milling insert 20 comprises a fixing part 201 matched with the milling insert mounting groove 1012 in size, a cutting edge 202 is arranged in front of the top of the fixing part 201, a through hole is formed in the middle of the fixing part 201, and the milling insert 20 is fixed on the fixing seat 101 after penetrating through the through hole and being in threaded connection with the screw fixing hole 1013 through a locking screw 30.
Further, in order to enable the milling cutter blade to bear higher cutting force, the thickness of the fixing seat 101 is larger than that of the cutter head 10, and the cross sections of the fixing seat and the cutter head are located on the same plane.
Further, in order to enable the chips to be quickly separated from the cutting edges, the upper part of the fixed seat 101 is provided with a chip removing groove 1014 along the circumferential direction of the cutter head 10.
Further, in order to facilitate the installation of the cutter, a cutter installation hole 102 is formed in the middle of the cutter head 10.
Further, in order to make the use of the cutter more stable, a cutter positioning hole 103 is further installed on the cutter head 10 on the side of the cutter installation hole 102.
The specific working principle is that as shown in fig. 2, when the cutting tool is used, the cutting tool is fixed on a driving shaft through a pressure plate and an auxiliary positioning bolt, so that the axis of the cutting tool is parallel to the axis of a copper pipe 40 to be cut, the two axes rotate in opposite directions, when four fixing seats 101 are provided, the rotating speed of the cutting tool is 1:1 compared with that of the copper pipe when the cutting tool is provided with four milling blades, when only two milling blades are arranged on the cutting tool (arranged diagonally), the rotating speed of the cutting tool is 2 times of that of the copper pipe, the cutting tool is pushed to gradually approach the copper pipe through a driving device, and square groove cutting is carried out on the copper pipe; similarly, when the number of the fixing seats 101 is two, two milling blades are installed, the rotating speed of the cutter is 2 times of that of the copper pipe fitting, the cutter is pushed by the driving device to gradually approach the copper pipe fitting, and square groove cutting is conducted on the copper pipe fitting. Only the environment of the tool and its working process will be described here, wherein the driving shaft and the driving device are not the technical solution of the present patent protection, and will not be described here.
The foregoing is illustrative of the present invention, and therefore, all such equivalent changes and modifications in the structure, features and principles described herein are intended to be included within the scope of the present invention.
