Assembling small bit tool
Technical field:
The utility model relates to a kind of cutting tool, particularly relates to a kind of facing cut cutterhead cutter.
Background technology:
Often adopt carbide mosaic on cutterhead in the general face milling technology, or carbide alloy is welded on the knife bar, again knife bar is contained on the cutterhead.These two kinds of forms are difficult to all guarantee that each blade participates in face milling simultaneously exactly, adjust inconvenience, and the waste of inefficiency, and Hardmetal materials simultaneously is big.
The utility model content:
The purpose of this utility model is: a kind of facing cut cutterhead assembled milling cutter head is provided, and this milling head is installed, the location is easy to adjust, can carry out face milling exactly, raises the efficiency.
The utility model is to constitute like this: it comprises blade (3), and blade (3) is connected with little cutter hub (1) by pressing plate (4), bolt (9).
Between blade (3) and little cutter hub (1) hard alloy blocks (2) is arranged, hard alloy blocks (2) is connected with little cutter hub (1) by bolt (8).Hard alloy blocks (2) can be protected little cutter hub (1), avoids by the smear metal scratch.
Outer surface part at pressing plate (4) covers hard alloy blocks (5), and the outer surface part of pressing plate (4) is connected with hard alloy blocks (5) by welding.Hard alloy blocks (5) protection pressing plate (4) is avoided by the smear metal scratch.
Adjustable plate (6), cushion block (7) are installed in the groove of little cutter hub (1), and the upper end of adjustable plate (6) withstands on the bottom of blade (3).
On (6) slotted hole is arranged at pressing plate (4), adjustable plate, bolt (9) is connected with little cutter hub (1) by slotted hole; The thickness of cushion block (7) has several specifications; The radial cutting size that can regulate blade (3) by adjustable plate (6), cushion block (7)
Between blade (3) and little cutter hub (1) excessive section, adjustment piece (10) is arranged, adjust piece (10) and be connected with little cutter hub (1) by bolt (11); The length d of adjusting piece (10) is made into several specifications, to regulate the axial cutting size of blade (3).
Locating shoulder (K) is arranged on little cutter hub (1), be used for little cutter hub (1) and be installed in location on the facing cutter.During installation, the knife bar of little cutter hub (1) is partly inserted in the hole on the facing cutter, after shoulder (K) axial location, with compressing member and threaded connector knife bar and facing cutter are fixed again.
The beneficial effects of the utility model are, can make milling cutter locate quickly and accurately, be installed on the facing cutter, increase work efficiency.

The specific embodiment:
Embodiment of the present utility model: make each part such as pocket knife body 1, hard alloy blocks 2, blade 3, and on pocket knife body 1, produce shoulder K, to be used to be installed in the axial location on the facing cutter, carrying out following assembling according to diagram connects: the first, earlier hard alloy blocks 2 usefulness bolts 8 are connected with pocket knife body 1; The second, blade 3 is placed on the pocket knife body 1, in the groove of pocket knife body 1, put into cushion block 7, adjustable plate 6; The 3rd, pressing plate 4 is withheld on blade 3 and pocket knife body 1, with bolt 9 pressing plate 4, blade 3, pocket knife body 1 are connected; The 4th, hard alloy blocks 5 is welded on the outer surface of pressing plate 4 with copper welding method; The 5th, will adjust piece 10 and be connected with pocket knife body 1 by bolt 11.
During use, small bit tool of the present utility model is installed on the facing cutter, the knife bar that is about to pocket knife body 1 partly inserts in the hole on the facing cutter, after shoulder K axial location, with compressing member and threaded connector knife bar and facing cutter is connected and fixed and gets final product.
