Abstract
The invention discloses an intersecting line outline chamfering tool for a cylinder pre-drilled opening, which solves the problem of poor cutting stability of the existing tool which is used for processing an intersecting line chamfering angle of a cylinder pre-drilled opening. The intersecting line outline chamfering tool comprises a tool bit lock bolt positioning table (10) inside an inner hole of a numerically controlled tool shank (4) between a blind rivet lock positioning screw (13) and a Morse taper shank positioning hole (12); a tool bit lock bolt (2) is in screw joint with a Morse taper shank tail thread positioning hole (3) in the tail part of a Morse taper shank (5) of a tool bit through a through hole (11) in the tool bit lock bolt positioning table (10); a blind rivet (1) is in screw joint with the blind rivet lock positing screw (13) in the left part of the inner hole of the numerically controlled tool shank (4) through a blind rivet lock positioning thread (14) at the head of the blind rivet (1); the diameter (D2) of a tool bit neck (6) of the tool bit is greater than the diameter (D1) of the root part of the Morse taper shank (5) of the tool bit, and an odd number of cutting edges (8) are arranged on on the tool bit. The intersecting line outline chamfering tool is especially suitable for processing the intersecting line chamfering angle of the cylinder pre-drilled opening.
Description
Technical field
The present invention relates to a kind of machine tool, particularly a kind of intersection profile chamfering tool that in the cylindrical shell pre-drilled cavity, uses.
Background technology
When processing cylindrical shell pre-drilled cavity intersection chamfering, most of large-sized numerical control equipment, such as traditional CNC milling machine, all adopt the processing of layer cutting method, the problem that these processing methods exist has: because the step pitch of processing is little, layering is many, the cutting feed speed is low, cutter for same particularly, its structure is not suitable for processing cylindrical shell pre-drilled cavity intersection chamfering, has caused processing length consuming time; The cutter tooth of existing cutter mostly is even number, and during cutter incision workpiece, the cutting force that produces mainly is converted into the shearing force axial to cutter, and single load bearing is larger, affects cutting stability; The bit-withdrawing slot of existing cutter is narrower, during large surplus cutting, causes the chip removal difficulty; In addition, also exist the surface roughness of work piece not reach the problem of mach requirement.
Summary of the invention
The invention provides a kind of cylindrical shell pre-drilled cavity intersection profile rose reamer, it is poor to have solved the cutting stability that existing cutter exists when processing cylindrical shell pre-drilled cavity intersection chamfering, the technical problem of chip removal difficulty and processing length consuming time.
The present invention is by the above problem of following solution:
A kind of cylindrical shell pre-drilled cavity intersection profile rose reamer, comprise the numerical control handle of a knife, blind rivet and cutter head, endoporus left part at the numerical control handle of a knife is provided with blind rivet locking positioning screw, endoporus right part at the numerical control handle of a knife is provided with the Morse taper shank locating hole, be provided with cutter head clamping screw positioning table in the endoporus of the numerical control handle of a knife between blind rivet locking positioning screw and Morse taper shank locating hole, the cutter head clamping screw is spirally connected by the Morse taper shank tailing screw flight locating hole of the Morse taper shank afterbody of the through hole on the cutter head clamping screw positioning table and cutter head, blind rivet by head blind rivet locking positioning screw thread and the blind rivet locking positioning screw of the endoporus left part setting of numerical control handle of a knife be spirally connected, the diameter of the cutter head neck of cutter head is greater than the root diameter (RD) of the Morse taper shank of cutter head, and the cutting edge on the cutter head is odd number.
The ratio of the length L 1 of cutter head column part and the length L 2 of the cutting edge on the cutter head is 1/2.
The present invention cooperates with " a cutter moulding " technology on Digit Control Machine Tool, can when satisfying product processing quality, technological requirement, greatly improve the working (machining) efficiency of product.The present invention has optimized the cutting ability of cutter, has satisfied well the technological requirement of cylindrical shell pre-drilled cavity intersection chamfering.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the A-A of cutter head of the present invention in Fig. 1 is to cutaway view.
The specific embodiment
A kind of cylindrical shell pre-drilled cavity intersection profile rose reamer, comprise numerical control handle of a knife 4, blind rivet 1 and cutter head, endoporus left part at numerical control handle of a knife 4 is provided with blind rivet locking positioning screw 13, endoporus right part at numerical control handle of a knife 4 is provided with Morse taper shank locating hole 12, be provided with cutter head clamping screw positioning table 10 in the endoporus of the numerical control handle of a knife 4 between blind rivet locking positioning screw 13 and Morse taper shank locating hole 12, cutter head clamping screw 2 is spirally connected by the Morse taper shank tailing screw flight locating hole 3 of the through hole 11 on the cutter head clamping screw positioning table 10 with Morse taper shank 5 afterbodys of cutter head, the blind rivet locking positioning screw thread 14 of blind rivet 1 by head is spirally connected with the blind rivet locking positioning screw 13 of the endoporus left part setting of numerical control handle of a knife 4, the diameter D2 of the cutter head neck 6 of cutter head is greater than the root diameter (RD) D1 of the Morse taper shank 5 of cutter head, and the cutting edge 8 on the cutter head is odd number.
The ratio of the length L 1 of cutter head column part 7 and the length L 2 of the cutting edge 8 on the cutter head is 1/2.
The present invention adopts " integral type " structure, and the present invention realizes and being connected and locking of the Morse taper shank 5 of cutter head by clamping screw 2.Be connected with the afterbody of numerical control handle of a knife 4 and locking by blind rivet 1, final realization is installed and is navigated on CNC milling machine or the machining center, carries out the purpose of Milling Process, has realized Milling Function again.
The present invention has increased the diameter D2 of the cutter head neck 6 of cutter head, and according to the principle of " one-inch short one-inch strong ", has suitably shortened the length L 1 of cutter head column part 7, has increased the cutting hardness of cutter.Tradition rose reamer L1/L2=3/4, rose reamer L1/L2=1/2 of the present invention.The present invention suitably increases the length L 3 of chip area 9 by the quantity of the cutting edge 8 of traditional cutter head of minimizing 1/5-1/7, reaches the purpose that increases the chip area degree of depth and width, the smooth and easy chip removal when having realized large surplus cutting.Tradition rose reamer L3 and difference (L1+L2) are the 8-10 millimeter, and the L3 of rose reamer of the present invention is the 3-5 millimeter with difference (L1+L2).
The present invention changes the quantity of cutting edge 8 into odd number by even number, by changing angle and the position in the relative cutter of cutting edge axle center, the cutting that has reached when changing cutting edge incision workpiece is subjected to force direction, disperse the effect of cutting force, play when reducing the cutter impulsive force, increase the cutting stability of cutter.
