Abstract
The utility model relates to an S-shaped internal thread ball end mill, which overcomes the defects of high difficulty, high cost and low accuracy existing in the process of forming an equal-wall stator by processing a drilling tool stator through a cutter. The technical scheme is that: the S-shaped internal thread ball end mill comprises a taper shank and a spherical cutter head frame at the front end of the taper shank, wherein the spherical cutter head frame is provided with at least two same end face cutters with S-shaped cutting blades which are positioned on the spherical cutter head frame. The S-shaped internal thread ball end mill has the advantages of simple processing process, high accuracy, capability of processing an equal-wall spiral groove in an inner hole of the drilling tool stator by milling, manually completed radial cutter feeding and no need of complex feeding mechanism, and is convenient and simple to operate.
Description
Technical field
The present invention relates to a kind of internal thread rose cutter, design a kind of S shape internal thread rose cutter that is used to process the housing internal thread especially.
Background technology
The develop rapidly of drilling technology, it is more and more general that helicoid hydraulic motor is applied in underground work, when needs high accuracy processing housing internal thread the time, a kind of method is casting method processing, to in the master pattern of processing in advance, adopt resin sand to add core and make core rod, employing divides the molded casting mold of making to case, smelts good molten steel by casting and casts, and the stator case of thread groove is arranged in Overheating Treatment forms.The method complicate fabrication process is easy to form the body defective, thereby influences the quality of product.A kind of method is by extrusion molding.To at first make roughcast, on extruder, steel pipe be pushed, extrude general shape, and then utilize smart mould on extruder, to revise the shape of housing, the housing of thread groove is arranged in the formation.The method, is difficult to realize when length is long if the specification of housing is big.A kind of is to adopt method for milling, by the milling of milling cutter, makes to form screw thread in the housing, and the cutter difficulty of processing of prior art is big, the cost height, and the precision of locating surface is difficult to control, and when cutting force became big, blade may be subjected to displacement, and repetitive positioning accuracy is difficult to guarantee.
Summary of the invention
The utility model is in order to overcome in the prior art, in the process of wall stators such as cutter processing drilling tool stator formation, difficulty is big, the cost height, the shortcoming that accuracy is low provides a kind of simple in structure, positioning accuracy and repetitive positioning accuracy height, processing is simple and the low a kind of S shape internal thread rose cutter of cost.
The technical scheme of this utility model employing is: a kind of S shape internal thread rose cutter, the ball-type cutter head frame that comprises taper shank and taper shank front end, ball-type cutter head frame is provided with at least two identical end face cutters with S shape cutting edge, and the end face cutter positioning of S shape cutting edge is on ball-type cutter head frame.
Effective benefit of the present utility model is: process is simple, and the accuracy height can be in the drilling tool stator inner hole wall helicla flute such as goes out by Milling Process, and radially feed does not need to relate to complicated radially delivering gear by manually finishing, and is easy to operate simple.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic diagram of blade of the present utility model.
Among the figure, 1 is taper shank, and 2 is positioning table, and 3 is ball-type cutter head frame, and 4 is the end face cutter.
The specific embodiment
Referring to accompanying drawing, the utility model is further detailed.
The utility model is in order to overcome in the prior art, in the process of wall stators such as cutter processing drilling tool stator formation, difficulty is big, the cost height, the shortcoming that accuracy is low, the technical scheme of employing is: a kind of S shape internal thread rose cutter comprises the ball-type cutter head frame of taper shank and taper shank front end, ball-type cutter head frame 3 is provided with at least two identical end face cutters 4 with S shape cutting edge, and the end face cutter 4 of S shape cutting edge is positioned on the ball-type cutter head frame 3.
In the technical solution of the utility model, have positioning table 2 on the taper shank 1.
In the technical solution of the utility model, the number of the blade of end face cutter 4 is 2-6.
In the technical solution of the utility model, the radius of curvature of end face cutter 4 is decided by the design size of institute's machining internal thread.
In the technical solution of the utility model, be provided with the disconnected groove of cutting between two end face cutters 4.
In the technical solution of the utility model, the disconnected well width of cutting between each end face cutter 4 is: 2-6mm.
The novel employing moulding vertical milling cutter of this practicality. Workpiece rotates around specific axle, and the utility model is done the axial feed motion by the knife bar drive when self rotates, process helicla flute in the screw drilling tool stator endoporus. The utility model is not radially feeding motion, and his radial feed is finished by artificial tool changing, does not need to design complicated delivering gear. Adding man-hour, the axis of rotation of axis of rotation of the present utility model and workpiece is orthogonal, therefore the utlity model has the working (machining) efficiency height. Since this practicality can basis actual conditions come the radian of process tool, so the machining accuracy height. The utility model also has long service life, cuts stably advantage.
