Description
Technical Field
The invention relates to the field of die machining, in particular to a replaceable alloy milling cutter structure for machining a fillet.
Background
At present, in the production process of an engine, parts such as a diesel engine body, a cylinder cover and the like frequently need to be changed in state, and the structural shape of a corresponding die is also changed frequently. For the modification of the die needing the additive, a inlaying process is often adopted. The mould inlaying process mainly comprises four steps: (1) and digging an insert position on the numerical control machining center, and digging out the old shape position. The insert position is determined according to the shape of the change position and is generally divided into square, round and special shapes. (2) And (3) machining an insert (3) to be inlaid according to the size of the cavity with the old shape position cut out, and installing a machining center again to mill the shape of the die after the inlaying work of a die worker by repairing the insert embedding position (4) is finished. In the process of machining the central insert position, a cutter radius circular arc (except the position where the insert is a cylinder) is left at the corner position of the insert position, usually R5, R6 and R8, so four corners of the embedded square insert are also machined and repaired into corresponding round corners.
The round chamfer of the insert is machined at the present stage, a fitter can directly grind the round chamfer into a required round angle by using an angle grinder, or the fitter can firstly mill an approximate round angle shape by using a milling machine and then grind and close the round angle by using the fitter. The fashioned fillet of pincers worker direct polishing only is applicable to less fillet, can consider the direct shaping of polishing of pincers worker when the grinding volume is little, to bigger fillet, needs the milling machine to process earlier. At present, when a milling worker processes machine legs and parts with transition arcs, the milling worker usually uses an arc milling cutter modified by a high-speed steel milling cutter or a welding blade type arc milling cutter. The angle grinder is time-consuming in grinding circular arcs, large in grinding amount, large in labor intensity and not attractive, and needs to be repaired repeatedly for multiple times. Because the round angle of polishing is irregular, the arc of the insert block is easy to generate a gap, and the quality of die change is affected. When the high-speed steel milling cutter is used for machining circular arcs, the milling cutter is long, the cutter is easy to wear, and only a slow feeding speed can be obtained. The use of the welding blade type arc milling cutter is high in cost, and the whole cutter needs to be brazed again or replaced after the edge is worn and broken. The cutter is easy to damage by milling the round and chamfering, the arc on the cutter is increased due to the cutter is easy to wear, and the cutter cannot be reused by grinding the cutter.
The above background disclosure is only for the purpose of assisting understanding of the inventive concept and technical solutions of the present invention, and does not necessarily belong to the prior art of the present patent application, and should not be used for evaluating the novelty and inventive step of the present application in the case that there is no clear evidence that the above content is disclosed at the filing date of the present patent application.

Further, the side portion of the chip groove and the side portion of the pressing plate are arc-shaped respectively, and the side portion of the chip groove and the side portion of the pressing plate are completely attached.
Furthermore, the tail of the pressing plate is provided with a boss, the front of the pressing plate is matched with the blade, and the boss at the tail of the pressing plate is matched with the chip discharge groove.
Further, after the blade is arranged on the blade mounting position, the height of the blade is 0.3-0.5mm higher than the table-board of the chip groove; the thickness of the boss is 0.3-0.5 mm.
Further, the cutter body is made of 40Cr alloy steel.
Further, the screw is a socket head cap screw.
Compared with the prior art, the invention has the advantages and beneficial effects that:
1. the cutter mainly comprises a cutter body, a blade, a pressing plate and a screw, wherein the side part of a chip discharging groove on the cutter body is arc-shaped, and the side part of the chip discharging groove and the side part of the pressing plate are completely attached, so that the pressing plate can be prevented from axially deviating due to impact force, the pressing force is enhanced, the blade displacement is prevented, meanwhile, the tail end of the pressing plate is provided with a boss, the height of the boss is consistent with the height of the blade higher than the chip discharging groove, the blade is pressed by the front end of the pressing plate, the middle section of the pressing plate is tightened by the screw, the boss at the tail end is.
2. The invention has the advantages that the blade is easy to replace, blades of different types can be replaced to mill parts of different materials, and simultaneously, the blades which are scrapped by jumping corners can be used for processing the blades used by the cost cutter, so that the utilization rate of the waste blades is improved, and the production and processing cost is saved.
3. The invention has the advantages of simple structure, replaceable cutter head, high utilization rate of the cutter head, stable processing and high efficiency.
