Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1, the present embodiment provides a cutter for a milling machine, including:
the tool rest 1 is provided with tool grooves 111 at two ends;
one end of the cutter bar 2 is fixed in the middle of the cutter frame and is arranged perpendicular to the cutter frame, and the other opposite end of the cutter bar forms a connecting end 21 which is used for being connected with a main shaft of a milling machine; the cutting knife comprises two cutting knives 3, wherein one end of each cutting knife is a head part 31, the other opposite end of each cutting knife is a cutting part 32, the head parts of the two cutting knives are respectively embedded into two knife grooves and can slide along the length direction of a knife rest, and the cutting parts extend out of the knife grooves and extend to one side far away from a knife bar;
the cutter frame is provided with an adjusting device, and the adjusting device is used for respectively driving the two cutting knives to slide in the cutter grooves so as to adjust the distance from the cutting knives to the axis of the cutter bar. The connecting end 21 is a cone.
When in use, the connecting end 21 is connected with a main shaft of a milling machine. The distance between the two cutting knives and the axis of the cutter bar is respectively adjusted by the adjusting device. Only one circular groove needs to be processed, so that the distance difference between the two cutting knives and the axial line of the cutter bar is smaller than or equal to the sum of the widths of the two cutting knives, at the moment, the milling machine is started, the main shaft of the milling machine drives the tool rest 1 to rotate through the tool bar, the two cutting tools respectively draw circles on the workpiece around the axis of the tool bar, in the process, the two cutting knives process the circular groove on the workpiece, because the distance difference between the two cutting knives and the axis of the knife rod is less than or the sum of the widths of the two cutting knives, therefore, the circular grooves of the two cutting blades are at least partially overlapped, thereby combining to form a circular groove, in the process, the cutting tool with the larger distance to the axis of the cutter shaft actually processes the outer diameter cambered surface of the circular groove, the cutting tool with the smaller distance to the axis of the cutter shaft actually processes the inner diameter cambered surface of the circular groove, and the two cutting tools respectively process the two cambered surfaces of the circular groove, so that the precision is improved conveniently. And the two cutting blades cut simultaneously, so the stress of the cutting blades is uniform. The adjusting device can respectively drive the two cutting knives to slide in the knife grooves so as to adjust the distance between the cutting knives and the axial line of the knife rod and adapt to processing circular grooves with different sizes. Similarly, if two concentric circular grooves are to be machined simultaneously, the distances from the two cutting tools to the axis of the cutter shaft are only required to be adjusted through the adjusting device, and the difference between the distances from the two cutting tools to the axis of the cutter shaft is larger than the sum of the widths of the two cutting tools. The utility model provides a pair of cutter for milling machine is convenient for process the ring groove.

Key grooves which are matched with each other are formed on the inner peripheral surface of the through hole 12 and the outer peripheral surface of the threaded end, and the key 5 is embedded into the key grooves to circumferentially fix the tool holder at the threaded end. The key may be a flat key or a spline. Through the structure, the cutter rest 1 and the cutter bar are fixed, so that the cutter rest is convenient to replace or maintain. In one embodiment of the present invention, the cutter bar is welded to the middle of the cutter holder, or the cutter bar and the cutter holder are integrally formed. So as to prevent the looseness between the cutter bar and the cutter frame.
As a further improvement to the above technical solution, the end of the tool holder 1 protrudes to a side away from the tool holder to form a boss 11, the tool slot is opened on the boss, the boss 11 is opened with a screw hole 112, the screw hole penetrates through the boss along a direction perpendicular to the axis of the tool holder and is communicated with the tool slot; the adjusting device comprises two adjusting components which are respectively arranged on the two bosses, each adjusting component comprises two screws 6, the two screws are respectively inserted into the cutter grooves along the two ends of the screw hole and abut against the two sides of the cutting cutters to clamp the cutting cutters, and the screws are in threaded connection with the bosses. Simple structure, the position of being convenient for adjust the cutting sword.
As a further improvement to the above technical solution, the adjusting assembly further comprises a pressing bar 7 slidably inserted into the knife groove and abutting against the cutting knife, wherein one of the screws is rotatably connected with the pressing bar. The pressing strip 7 is abutted against the cutting blade so as to ensure the correct position of the cutting blade in the cutter groove.
Referring to fig. 2, as a further improvement of the above technical solution, another embodiment of the present invention provides a milling machine tool, a vertical groove 71 is formed on a surface of the pressing strip 7 contacting the cutting blade, and a positioning protrusion 33 is disposed on the cutting blade 3 and is embedded in the vertical groove. The cutting knife 3 and the pressing strip 7 are prevented from sliding relatively, and the processing precision is improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
