Abstract
The utility model relates to a mechanically-clamped indexable crankshaft molding milling cutter which comprises a cutter body (1), blades (2), wedge blocks (3), cutter shims (4), screws (5) and dowel screws (6), wherein the tooth sockets are arranged on the cutter body (1), the cutter shims (4) are fixed in the tooth sockets on the cutter body (1) via the screws (5), the blades (2) are pressed in the tooth sockets through the wedge blocks (3) and through the dowel screws (6) by adopting a flush mounting method and spirally arranged in the cutter cutting area in groups, and two adjacent groups or more groups of the blades (2) are mutually lapped to form a complete molding cutting edge. The utility model has the advantages that the intermediate blade has no back angle, eight edges are variable for each blade, and as for the molding blades on the side, four edges are variable for each blade, therefore, the utilization ratio of the blades is improved to the utmost extent, the milling cutter is energy-saving and environment-friendly and is quick and easy for cutting by adopting the flush mounting structure, and since more blades are arranged on the cutter head, the milling cutter has the advantages of high processing efficiency, stable cutting, simple structure and good accuracy retention.
Description
Technical field
The utility model relates to a kind of milling cutter, is specifically related to a kind of machine clip variable-position bent axle profile milling cutter.
Background technology
At present, domestic Production of Crankshaft producer is in the processing to the trunnion of bent axle and rod journal, particularly adopt milling process to add man-hour, employed integral shaft milling cutter has two kinds of structures: a kind of is that blade adopts upright dress, and blade directly is fixed in the insert groove by screw, and the shortcoming of this structure is that cutter hub is damaged easily when the blade tipping, and cutter hub can not be repaired, the waste that causes is very big, and the while is because structure is upright dress, and is very high to power, the rigidity requirement of lathe; Another kind of structure is that same employing of blade found dress, blade directly is fixed in the insert groove of cutter piece by screw, the cutter piece is connected on the cutter hub by screw, this structure requires the height except power, the rigidity to lathe, cutter is made and is required very high to machine tool accuracy, production cost height, this structure are mainly used in the production occasion of the many kinds of small lot.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcomings and deficiencies of prior art; a kind of machine clip variable-position bent axle profile milling cutter is provided; this profile milling cutter not only can protect cutter hub not to be destroyed; can arrange more blade and form more effectively cutting edge; the utilization rate of blade can be improved to greatest extent, and the streamline batch process can be adapted to well.
The purpose of this utility model is achieved through the following technical solutions: a kind of machine clip variable-position bent axle profile milling cutter, and it is by cutter hub, blade, voussoir, edge bearing, screw and dowel screw are formed.Cutter hub is provided with teeth groove, and edge bearing is fixed in the teeth groove on the cutter hub by screw, and blade adopts paperback, and is pressed in the teeth groove through dowel screw by voussoir.Blade is arranged in the cutter hub cutting region in groups spirally, two adjacent groups or organize blade more and overlap out complete forming and cutting sword mutually.
Edge bearing is fixed in the teeth groove on the cutter hub by screw, and blade adopts paperback, and is pressed in the teeth groove through dowel screw by voussoir.Specifically be to say, edge bearing is fixed in the cutter hub teeth groove by screw, and blade is installed in the edge bearing, blade and edge bearing is pressed in the cutter hub teeth groove through dowel screw by voussoir again.
Blade paperback, the big face that specifically is meant blade be as rake face, and the purpose that blade is installed like this is in order to make cutting more brisk, and the blade of installation is more.
Intermediate blades does not have relief angle, and every blade can be with eight swords, the shaping blades on the limit, and every blade can improve the utilization rate of blade, energy-conserving and environment-protective to greatest extent with four swords.
By top narration as can be seen, the utlity model has following advantage: blade adopts paperback, makes that cutting is brisk, so and the many working (machining) efficiency height of the blade number of arranging on the cutterhead, stable cutting, and also simple in structure, precision keeps; Blade is installed on the edge bearing, can protect cutter hub not to be damaged effectively, thereby prolongs the cutter hub life-span.
