Abstract
The utility model provides a processing blade blade root recess is with crisscross tooth milling cutter, it relates to processing blade blade root milling cutter for the recess, concretely relates to processing blade blade root recess is with crisscross tooth milling cutter. The utility model discloses a solve because the cutter adopts straight flute type of construction, and when milling the blade root recess, the resistance to cutting is big, and the machining precision is poor in the present blade blade root course of working problem that machining efficiency is low. The utility model discloses a tool bit, handle of a knife and connecting rod, tool bit pass through the connecting rod to be connected with the head end of handle of a knife, and circumferencial direction staggered arrangement's octadentate structure is followed by four left chute teeth and four right chute teeth to the tool bit, and the inclination of every left chute tooth and every right chute tooth is 10, and the sword anterior angle of tool bit is 15, and the sword relief angle of tool bit is 8. The utility model belongs to the machining field, an.
Description
Technical field
This utility model relates to a kind of processing blade root groove milling cutter, is specifically related to a kind of processing blade root groove and hands over
Staggered tooth milling cutter, belongs to field of machining.
Background technology
Blade is a vitals of steam turbine, blade with blade root location and installation in turbine rotor blade root groove, blade
Blade root groove uses special-purpose milling cutter to be processed, and former cutter is cylinder caudal peduncle, straight groove structure milling cutter, owing to cylinder staight shank is tied
Structure makes cutter clamp intensity difference, affects working (machining) efficiency, owing to cutter uses straight groove structure pattern, during milling blade root groove,
Resistance to cutting is big, and machining accuracy is poor, and working (machining) efficiency is low.
Utility model content
This utility model is for solving owing to cutter uses straight groove structure pattern in the existing blade root course of processing, and milling blade root is recessed
During groove, resistance to cutting is big, and machining accuracy is poor, the problem that working (machining) efficiency is low, and then proposes one processing blade root groove
Use staggered tooth milling cutter.
This utility model adopts the technical scheme that for solving the problems referred to above: this utility model includes cutter head, handle of a knife and connecting rod,
Cutter head is connected with the head end of handle of a knife by connecting rod, and cutter head is by four left skewed slot teeth and four right skewed slot teeth along the circumferential direction
Staggered octadentate structure, the angle of inclination of each left skewed slot tooth and each right skewed slot tooth is 10 °, before the cutter of cutter head
Angle is 15 °, and the cutter relief angle of cutter head is 8 °.
Further, the outline of handle of a knife is the most tapered to aft end by its head end, and the tapering of handle of a knife is Mohs three cone
Degree.
Further, the aft end of handle of a knife is provided with the screw of M12.
The beneficial effects of the utility model are: this utility model is improved to Mohs 3 taper shank due to handle of a knife, substantially increases cutter
Chuck strength, owing to cutter grooved is improved to zigzag tooth grooved by straight trough, left and right angle of bevel is 10 °, and hands over every tooth
Mistake, i.e. one tooth be left skewed slot, a tooth be right skewed slot, be crisscross arranged, utilize the cutter developed to be processed blade root
Groove, substantially increases cutter chuck strength, reduces resistance to cutting, and working (machining) efficiency is enhanced about more than once, Surface Machining matter
Measure and improved to Ra3.2 by former Ra6.3.
