Description
Technical field:
The present invention relates to method for processing gear inner hole key slot and device.
Background technology:
Gear is the fundamental parts of machine, and most gears all will connect by key realizes and the connecting of axle that thereby the crudy of keyway counts for much.Traditional processing technology has: draw keyway with broaching machine, use the slotting machine keyseat, also wired cutting, electric spark, laser etc.In these traditional processing technologys, broaching machine broaching machining characteristics one is the productivity ratio height, if but the workpiece quantity that needs broaching not for a long time, then the broaching machine utilization rate is low, causes the equipment waste easily; The 2nd, the range of work is wide, and machine tool structure is simple, and is easy to operate; The 3rd, the complex structure of broaching tool, each surface of broaching all will be with special broaching tool, and the expense height of manufacturing and sharpening; The 4th, it is big that broaching machine accounts for plant area, the energy consumption height, and noise is big; The 5th, the costing an arm and a leg of broaching machine, inapplicable for general scale enterprise.The efficient of slotting machine keyseat is low, all needs correction reference again during processing parts, and precision is not high, and fineness is low; The efficient of line cutting, electric spark is lower; The laser process equipment costliness.
Summary of the invention:
The process and the isolated plant that the purpose of this invention is to provide the processing of a kind of bore single key slot, the pressure by the press push rod promotes gang tool and goes out single key slot at workpiece endoporus broaching, and its stable processing quality, precision height, fineness are good, easy and simple to handle.
Bore single key slot processing method is: it comprises following technological process: supporting seat (4) is fixed on the press workbench (7), workpiece (5) is positioned on the supporting seat (4), workpiece (5) endoporus is inserted at the taper seat guiding position of gang tool, the pressure mandril of press (6) is pressed gang tool the endoporus that passes workpiece (5), the push broach of gang tool (1) cuts out keyway, unclamp push rod (6) and take off workpiece and gang tool, promptly realize a working angles, finish the processing of a keyway.
Gang tool of the present invention not only directly processes keyway, and leads, locatees, goes out design teams such as cutter and be integrated.
Gear inner hole key slot processing is to constitute like this with isolated plant: it comprises press and pressure mandril (6), supporting seat (4) is arranged on press workbench (7), workpiece (5) is arranged on supporting seat (4), between workpiece (5) and pressure mandril (6), gang tool is arranged.
Gang tool comprises push broach (1), broach shell (2) and lock screw (3), and push broach (1), broach shell (2) connect by lock screw (3).
Two through holes are arranged in push broach (1), two screwed holes are arranged on broach shell (2), push broach (1) is connected by lock screw (3) with broach shell (2).
Broach shell (2) becomes the awl column towards the end of workpiece (5), with the usefulness that leads when inserting workpiece (5) endoporus, and can be perpendicular to workpiece and self-centering.
Broach shell (2) middle part has and the friction tight cutter groove of putting of push broach (1), is convenient to push broach is fitted together with broach shell closely.
The length of putting the cutter groove is than the long 0.5-1mm of push broach (1).
The cylindrical at broach shell (2) middle part be designed to workpiece internal orifice dimension 6g to the interference fits of 7g level or higher, guarantee the dimensional accuracy and the quality of stability of workpiece inner hole key slot like this, and mill off puts two sharp limits on the knife face, be used for holding bits and cutter dispels the heat.
Broach shell (2) is designed to less than the workpiece internal orifice dimension towards the upper diameter of the pressure mandril (6) of press, and its length is longer than the thickness 2-10mm of workpiece (5), press like this when cutting push broach pressed pass workpiece after whole gang tool can take off from workpiece very easily.
Broach shell (2) adopts the steel alloy manufacturing, through integral quenching and surfaces nitrided processing.
Supporting seat (4) not only is used for supporting workpiece, but also is designed to conveniently take off the structure of cutter.
Push broach is installed in when putting in the cutter groove, is close to the broach shell heating and with the upper surface of push broach earlier and puts cutter groove top, the lock screw of screwing on; So just increased the rigidity of push broach,, guaranteed that lock screw can not cut off with push broach can in broach shell, not slide because thrust is directly delivered to the upper surface of push broach by broach shell when the broaching keyway.
Broach shell is according to different workpieces endoporus and the design of keyway dimensional requirement, and different push broach and broach shell are combined in a workpiece that can process more specifications.
The invention has the advantages that: compare with cutter with conventional traditional handicraft, easy and simple to handle, the production efficiency height, steady quality, the precision height, production and equipment cost are low, and it is little to account for plant area, equipment conveniently moving, long service life.The present invention can be widely used in that length of cut is little, the endoporus single key slot of non-ferrous metal and plastics etc.
Description of drawings:
Fig. 1 is gear inner hole key slot processing isolated plant schematic diagram.
Fig. 2 is a gang tool device front view of the present invention.
Fig. 3 is schematic diagram, the front view of the push broach (1) of gang tool.
Fig. 4 is schematic diagram, the front view of the broach shell (2) of gang tool.
The specific embodiment:
Embodiments of the invention: as shown in Figure 1, bore single key slot processing process comprises following operation: supporting seat 4 is fixed on the workbench 7, workpiece 5 is positioned on the supporting seat 4, workpiece 5 endoporus are inserted at the conical surface guiding position of the broach shell 2 of gang tool, starting press makes pressure mandril 6 that push broach 1 pressure of gang tool is passed workpiece 5, unclamp push rod 6 and take off workpiece 5 and gang tool, the keyway process finishing.
