Abstract
The utility model discloses a milling cutter for processing the shaping surfaces of a side frame of a railway freight car. The cutting face of a cutter body is a shaping surface of an annular groove, wherein, the cross section of the annular groove is a rectangular groove, and the notch face outwards. The milling cutter has the advantages of simple processing mode, high processing efficiency, good processing quality, adjustable width of the milling cutter, etc.
Description
The utility model belongs to machining tool, specifically is used for the special-purpose milling cutter of railway freight-car bogie side frame milling machine processing railway freight-car bogie side frame.
The bogie side frame of railway freight-car is the position that is used to install wheel because the wearing and tearing in using need often processing to repair, existing processing method be after the built-up welding more by hand emery wheel polish.Manual emery wheel mill bogie side frame 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.
The purpose of this utility model provides a kind of milling cutter that is exclusively used in railway freight-car bogie side frame Milling Process, to overcome the deficiencies in the prior art.
The utility model can be realized by following structure: the utility model is a kind of profile milling cutter that adopts indexable insert tip, throw away tip to form.It has cutter hub, and groove and cutter hole are cut by the row of being processed with on cutter hub, and blade is fastened on the cutter hole with screw, is processed with keyway at the back of cutter hub.Main points of the present utility model are: an end of cutter hub is a handle of a knife, and the other end is cutter back shaft and cutter locking nut.The cutting face of cutter hub is that a cross sectional shape is the outside endless groove profile of rectangular channel and notch, and three faces in the notch all are the cutting faces, and the angle between adjacent two cutting faces is 90 °.The molded lines that processes is the part molded lines that adjacent birectangular rectangle is arranged.Cutter hub can draw back separated into two parts along the axis of milling cutter from the junction in adjacent two cutting faces or from any of cutting face, middle part, and in use, two parts of milling cutter are combined into one along the axial-movement of milling cutter, form a complete grooved cutting face.The width in grooved cutting face can be adjusted.
Another implementation structure of the present utility model is: the profile milling cutter of the adjustable cutting face width in three cutting faces, have two cutting faces relative and parallel and perpendicular to the axis of milling cutter, the 3rd cutting face is between these two cutting faces and vertical with these two cutting faces respectively.
The utility model compared with prior art has: working (machining) efficiency height, crudy height, labour intensity be little, do not damage advantages such as the workman is healthy.
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:
Fig. 1 is the front view of the utility model structural representation,
Fig. 2 is the left view of the utility model structural representation,
Fig. 3 is the right view of the utility model structural representation,
Fig. 4 is the three-dimensional view of the utility model structural representation.
In conjunction with Fig. 1～4, railway freight-car bogie side frame milling cutter, cutter hub 1 is arranged, on cutter hub 1, there is row to cut groove 2 and cutter hole 3, blade 4 usefulness screws fastening 5 are on cutter hole 3, be processed with keyway 6 at the back of cutter hub 1, one end of cutter hub 1 is a handle of a knife 7, the other end is cutter back shaft 8 and cutter locking nut 9, the cutting face 10 of cutter hub is that a cross sectional shape is the outside endless groove profile of rectangular channel and notch, three faces in the notch all are the cutting faces, angle between adjacent two cutting faces is 90 °, the molded lines that processes is the part molded lines that adjacent birectangular rectangle is arranged, cutter hub can draw back separated into two parts along the axis of milling cutter from the junction in adjacent two cutting faces or from any of cutting face, middle part, and in use, two parts of milling cutter are combined into one along the axial-movement of milling cutter, form a complete grooved cutting face, the width in grooved cutting face (12) can be adjusted with packing ring 11.
The utility model is for the process tool of processing side frame of train wagon, has good processing accuracy , working (machining) efficiency height, little, the no dust of labour intensity and the little advantage of cutter expense, therefore promote Have a extensive future.
