Description
Technical Field
The utility model belongs to the technical field of machining cutters, and particularly relates to a grooving milling cutter disc.
Background
The iron or aluminum metal accessories widely used in the power transmission and transformation system, which are collectively called as hardware fittings, need to bear large pulling force during operation to ensure good electrical contact. The hanging plate comprises a ball head hanging plate, a socket head hanging plate and the like, is a plate type connecting piece with two ends assembled by bolts, is an axially symmetric connecting hardware fitting, has wide contact surface and strong abrasion resistance, and is commonly used for connecting an iron tower and a ground wire; the hanging plate is generally processed by cutting grooves in the processing and forming process, the middle of the thick plate with the holes is milled with the grooves, so that the two sides of the hanging plate form symmetrical hanging plates, and because the bottom surfaces of the grooves require the tangent plane to be round and smooth, edges and corners can not be stored, and the requirement can not be met by using a common slotting cutter or a milling cutter head.

Adopt three blade milling flutes, wherein first group chamfer blade and second group chamfer blade can mill the chamfer of tank bottom surface, and the tank bottom plane is milled to the third group blade, because three group blades have overlap portion each other between chamfer and the plane, so can the smooth linking, and the tank bottom surface of milling accords with the requirement of link plate link fitting.
Furthermore, a plurality of cutting teeth are arranged on the circumferential surface of the cutter head at intervals at equal intervals, and a parallelogram blade is fixedly connected to the front end of each cutting tooth along the rotating direction of the cutting tooth by a screw. Because the middle part of the bottom of the groove is wider than the two chamfer parts, the number of the third group of blades is more than that of the two groups of chamfer blades in order to ensure the milling effect, and therefore, a parallelogram blade is arranged on each cutting tooth.
Furthermore, each cutting tooth is further provided with a blade mounting cavity, the blade mounting cavities of two adjacent cutting teeth are arranged on the first periphery or the second periphery in a staggered mode, and each blade mounting cavity is detachably provided with a circular blade. Because the thickness of blade disc body and cutting teeth is limited, it is difficult to set up two blade installation cavities on same cutting teeth, because the installation of blade installation cavity is the circular blade that mills the chamfer, the area of milling of chamfer itself is little, need not set up too much circular blade, consequently staggers the setting on adjacent cutting teeth with the blade installation cavity interval of installing circular blade to satisfy the requirement of milling of two symmetrical circular chamfers.
Furthermore, a cutter holder is fixedly arranged in the blade mounting cavity, a blade accommodating groove is formed in the cutter holder, and the circular blade can be embedded into the blade accommodating groove and is fixedly connected with the cutter holder through a screw. The detachable design can be changed conveniently when the circular blade is damaged.
Furthermore, an oil hole is formed in the blade mounting cavity, the oil hole penetrates through the cutting teeth, and two ends of the oil hole respectively lead to the first end face and the second end face. The oil hole is convenient for the cutting fluid to lubricate and cool the circular blades at the first periphery and the second periphery.
Further, the circular blade is a circular truncated cone-shaped blade with a threaded hole in the center, the end face with the larger diameter in the circular truncated cone-shaped blade is outwards installed in the blade accommodating groove, the periphery of the end face with the larger diameter is an arc edge, and the arc edge is arranged in a protruding mode relative to the tool holder. The circular arc edge formed by the circular truncated cone-shaped blade can meet the milling requirement on a workpiece, is not too sharp, can protect the edge part from breaking, and prolongs the service life of the circular blade.
Further, the radius of the circular arc edge is 8 mm.
Furthermore, the core part of the cutter head body is provided with a mounting hole, and a key groove is formed in the mounting hole.
Furthermore, four lightening holes are formed around the center on the cutter head body.
Further, the thickness of the cutter head body is 38 mm.
Compared with the prior art, the utility model has the beneficial effects that: the grooving milling cutter disc is used for machining a hanging plate type connecting piece in an electric fitting, when the grooving is conducted, three groups of blades are adopted for milling round chamfers at the middle plane and two corners of the bottom of the groove respectively, and the three groups of blades can mill smooth and round straight-curved connecting faces; the three groups of blades respectively mill different parts, so that a more accurate milling effect can be achieved, compared with the use of a one-piece cutting edge, the cutting force is dispersed to the three groups of blades, the blade part can be effectively prevented from being worn and broken, and the service life of the cutter head is prolonged; in addition, three groups of blades are all connected to the cutting teeth in a detachable mode, and when a single cutting blade is damaged, the cutting blade can be replaced in time, so that the cutting blade is more flexible and convenient to use.
