Abstract
The utility model discloses a special milling cutter for milling railway coupler yoke keys, which comprises a cutter handle, a cutter body, an indexable cutter blade and a screw. The milling cutter can process the railway coupler yoke keys which are repaired and welded and can also manufacture the new coupler yoke keys. The utility model has the advantages of good processing precision, high work efficiency and no pollution.
Description
The utility model belongs to machining tool, and specifically it is a kind of special-purpose milling cutter that is applicable to processing railway locomotive, vehicle hitch coupler yoke key.
Railway locomotive, vehicle are walked on railway, the coupler yoke key of its hitch is used for guaranteeing its connection and passes on tractive force, in use because of the stressed very conference of coupler yoke key causes very big wearing and tearing, need often processing to repair, its process be after the repair welding more by hand emery wheel polish.Manual wheel grinding has a lot of shortcomings, and 1 labour intensity is big, and 2 processing dimensions are difficult to guarantee that the big workers ' health of 3 dust does not guarantee, 4 long processing times, and 5 is dangerous big.In the manufacture process of coupler yoke key,, make general manufacturing process be difficult to process and the mode of having taked not process, therefore also greatly reduce the workmanship of coupler yoke key also because the special shape of coupler yoke key.Change the drawback in above manufacturing and the repair procedures, must adopt special manufacturing process is the profile milling.
The purpose of this utility model provides that a kind of workpiece machine-shaping is good, working (machining) efficiency is high, labour intensity is little, no dust, non-hazardous special-purpose milling cutter, to overcome the deficiencies in the prior art.
The utility model is a kind of profile milling cutter that adopts indexable insert tip, throw away tip, the utility model can be realized by following structure: it has cutter hub, handle of a knife, on cutter hub, be processed with cutter hole and row cuts groove, blade is fastened on the cutter hole with screw, has a slice indexable insert tip, throw away tip at least at the same cutting position of the circumferencial direction in milling cutter cutting face.Main points of the present utility model are: (the section configuration sub-elliptical of coupler yoke key part of the force when the workpiece vertically-arranged is processed, when being parallel to the processing of milling cutter axis, long axis of ellipse is considered as horizontal processing, when being parallel to the processing of milling cutter axis, the minor axis of ellipse is considered as vertically-arranged processing, horizontal or vertically-arranged processing all need processing 180 ° of processing of rear flank upset opposite side), the cutting face of cutter hub is the shallow/deep groove type arc surface, the width in cutting face equals the thickness of locomotive coupler coupler yoke key, arc radius equals the arc radius in the section configuration of locomotive coupler coupler yoke key part of the force, the cutting molded lines is that 1/2 inside circular arc of two parallel lines and nock is tangent, and the molded lines that cuts accords with the part of the section configuration of locomotive coupler coupler yoke key part of the force; When the workpiece horizontal adds man-hour, one end of cutter hub has handle of a knife, the cutting face of cutter hub is a sipes type arc surface, the width in cutting face equals the width of locomotive coupler coupler yoke key part of the force, arc radius equals the arc radius in the section configuration of locomotive coupler coupler yoke key part of the force, the cutting molded lines is that the two ends of straight line respectively are connected with a nock to 1/4 right circular arc line, and the molded lines that cuts accords with half of section configuration of locomotive coupler coupler yoke key part of the force.
The utility model also has another version: remove handle of a knife and process the milling cutter installing hole on the basis of above-mentioned two kinds of milling cutters on milling cutter, use is by the milling cutter installing hole milling cutter to be installed.
The utility model compared with prior art has: labour intensity is low, crudy height, working (machining) efficiency height, no dust, non-hazardous advantage.
Accompanying drawing has provided an embodiment of the present utility model, further specifies concrete structure of the present utility model below in conjunction with accompanying drawing:
The front view of the utility model structural representation when Fig. 1 is the processing of workpiece vertically-arranged,
The left view of the utility model structural representation when Fig. 2 is the processing of workpiece vertically-arranged,
The stereogram of the utility model structural representation when Fig. 3 is the processing of workpiece vertically-arranged,
Fig. 4 is the utility model and the relative Working position figure (during the workpiece vertically-arranged) of workpiece,
Fig. 5 is the utility model and the relative Working position figure (during the workpiece horizontal) of workpiece,
In conjunction with Fig. 1～3, coupler yoke key milling cutter during the processing of workpiece vertically-arranged, groove 2 and cutter hole 3 are cut by the row of being processed with on cutter hub 1, blade 4 usefulness screws 5 are fastened on the cutter hole 3, end at cutter hub 1 has handle of a knife 6, the cutting face 7 of cutter hub is the shallow/deep groove type arc surface, and the cutting molded lines is that 1/2 inside circular arc of two parallel lines and nock is tangent, and the molded lines that cuts accords with the section configuration with locomotive coupler coupler yoke key part of the force.The width 8 in its cutting face 7 equals the thickness of locomotive coupler coupler yoke key, and circular arc 9 radiuses equal the arc radius in the section configuration of locomotive coupler coupler yoke key part of the force.
Fig. 4 is the utility model and the relative Working position figure (during the workpiece vertically-arranged) of workpiece, 10 coupler yoke key milling cutters when being the processing of workpiece vertically-arranged among the figure, and 12 is coupler yoke keys among the figure.
Fig. 5 is the utility model and the relative Working position figure (during the workpiece horizontal) of workpiece, and 11 is coupler yoke key milling cutters that the workpiece horizontal adds man-hour among the figure, the 12nd, and coupler yoke key.
The utility model is the process tool for the processing flat pin of coupler tail of railway coach, has the processing essence Spend, no dust, the high and little advantage of cutter expense of working (machining) efficiency, so promotion prospect is wide.
