Fig. 2 is a side view of a blade slot cutter in an embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1 and 2, a saw blade slot milling cutter comprises a disc-shaped milling cutter blade 1, eight cutting portions 2 are uniformly distributed on the circumferential surface of the milling cutter blade 1, a chip discharge groove 3 is formed between adjacent cutting portions 2, a diamond blade 4 is arranged in the chip discharge groove 3, two ends and side surfaces of the diamond blade 4 protrude out of the corresponding cutting portions 2, a positioning hole 11 corresponding to a cutter bar is arranged in the center of the milling cutter blade 1, a shaft shoulder 5 protrudes outwards from the center of one side end surface of the milling cutter blade 1, the positioning hole 11 penetrates through the shaft shoulder 5, a cooling hole 51 corresponding to the diamond blade 4 is arranged in the shaft shoulder 5, a communicated annular cooling groove 111 is concavely arranged on the inner wall of the positioning hole 11, and the cooling hole 51 is communicated with the cooling groove 111.

Among this technical scheme, milling cutter piece, cutting part and shaft shoulder integrated into one piece form, ensure its joint strength, smooth transition of shaft shoulder and milling cutter piece junction, diamond blade chooses polycrystalline diamond compact for use to make, be applicable to the cutting high rigidity alloy, timber, nonmetal such as pottery, the cutting and the processing of non-ferrous metal and other metals, higher hardness and wearability have, cutting accuracy is high, enlarge saw bit groove milling cutter's application scope, set up in the cutter arbor one communicate in the connecting hole of cyclic annular cooling bath can, shunt the coolant liquid to the cooling hole through cyclic annular cooling bath, to the cooling of every cutting part, improve the cooling effect, cooling bath and cooling hole set up in the shaft shoulder, guarantee the intensity of milling cutter piece itself, through setting up the shaft shoulder, a plurality of saw bit groove milling cutters directly use side by side, need not to add the gasket interval in addition.

Referring to fig. 2, the inner wall of the positioning hole 11 is recessed with a key groove 112.

In the technical scheme, the surface of the cutter bar is provided with a key matched with the key groove and used for circumferential positioning of the milling cutter blade, so that relative rotation between the milling cutter blade and the cutter bar is avoided.

Referring to fig. 1 and 2, a protection boss protrudes from the center of the end face of one side of the milling cutter blade 1, which is away from the shaft shoulder 5, and a positioning hole 11 penetrates through the protection boss 6.

In the technical scheme, the protection boss protrudes out of the corresponding end face of the diamond blade and is matched with a nut, a gasket and the like to fix the milling blade on the cutter bar.

Referring to fig. 2, the chip grooves 3 are right-angle grooves, the included angle between the plane where the cutting edge of the diamond blade 4 and the central axis of the milling blade 1 are located and the rake face of the diamond blade 4 is alpha, and the value of alpha is 5 degrees.

Among this technical scheme, the chip groove is the right angle groove, and the opening is big, does benefit to the piece and discharges, avoids the sweeps overstock, prevents that the cutter from generating heat, is favorable to the heat dissipation, and diamond blade's rake face and milling blade correspond between the surface of revolution slope 5, do benefit to the chip removal, and simultaneously, the cutter atress is not simply along milling blade's tangential direction, and the protection cutter reduces the condition emergence of damage cutters such as disconnected sword or tipping.

Referring to fig. 1, the cutting edge of the diamond blade 4 forms an angle β with the central axis of the milling blade 1, the value of β being 3 °.

Among this technical scheme, when this stage property was fed with the part axial relatively, the volume of eating was increaseed along the cutting edge gradually, and the condition of avoiding tipping etc. to damage the cutter takes place.

In conclusion, the milling cutter is simple in structure, the shaft shoulder is arranged, the plurality of saw blade slot milling cutters are directly used in parallel without additionally arranging a gasket at intervals, and the cooling slots and the cooling holes are arranged in the shaft shoulder, so that the strength of the milling cutter blade is guaranteed.
