Description
Affiliated technical field
The utility model belongs to machining tool, and specifically it is a kind of special-purpose milling cutter that is used to process the rolling stock cartridge.
Background technology
The rolling stock cartridge is the link between the car body partial sum running part of vehicle, in use can cause very big wearing and tearing or rhegma, needs often processing to repair, and its course of processing is to rebuild with machining tool after the repair welding again.Existing best job operation is to mill with the cartridge milling machine to repair, and cutter is the profile milling cutter, and existing milling cutter can once mill out the original profile of cartridge.But, in actual use, because the abrasion degree of depth difference of cartridge wherein has the abrasion degree of depth greatly in allowing limit.So, often execute and repair according to the actual wear degree of depth situation of cartridge, do not need cartridge is returned to prototype.Executing according to the actual conditions of cartridge in the process of repairing in order to increase the service life of cartridge, requiring the depth direction of cartridge or short transverse is not cut or few cutting.And existing cartridge milling cutter is that the distance between the following dome arc cutting blade of the last concave arc cutting blade of cartridge milling cutter and cartridge milling cutter can not be adjusted by the prototype of cartridge.Therefore, can only cut the cartridge of a kind of constant depth or height, i.e. prototype cartridge has limited the Applicable scope of cartridge milling cutter widely.
Summary of the invention
The purpose of this utility model provides a kind of cartridge adjusted milling cutter that can adapt to different depth or the processing of height rolling stock cartridge, to overcome the deficiencies in the prior art.
The technical scheme that its technical matters that solves the utility model adopts is: adopt indexable insert tip, throw away tip to constitute the cartridge milling cutter of cutting edge, be processed with cutter hole and row and cut groove on cutter hub, blade is fastened on the cutter hole with screw.The cutting molded lines of cutter hub cutting edge is that the bus of cutting edge is: and the cutter hub axis in a plane and and the two ends of the uneven one section straight line of cutter hub axis respectively have a circular arc and this section straight line tangent, from the center of circle of the near end circular arc of cutter hub axis between cutter hub axis and this section straight line, in this section straight line outside, and this circular arc can move along straight line from the center of circle of a cutter hub axis end circular arc far away.Formation is a dome arc cutting edge from the cutting edge of the near circular arc of cutter hub axis, its radius can cutting at one time goes out the recessed fillet of the circular load plane of vehicle truck center plate that radius meets the railway regulation and the diametric side junction adjacent with it, and the recessed fillet of diametric side of body center plate and the non-bearing plane junction adjacent with it.From dome arc cutting edge upwards and the tangent linear portion cutting edge of dome arc cutting edge be the circumferential teeth of milling cutter, also be the side cutting edge, make progress the side cutting edge of milling cutter with respect to milling arbour alignment outer incline from milling cutter dome arc cutting edge.The movable tool rest that can move up and down is installed on cutter hub, and the locating surface of tool rest on cutter hub is the inclined-plane, and the gradient on inclined-plane is identical with direction with the gradient of the side cutting edge of direction and milling cutter.Tool rest is fastened on the cutter hub with screw, unclamp screw after tool rest can move up and down along the inclined-plane on the cutter hub.Blade is installed on tool rest, and blade is fastened on the tool rest with screw.Blade is the concave arc cutting edge, the dome angle of the junction, non-bearing plane that the diametric side of vehicle truck center plate that this arc edge energy cutting at one time goes out the railway regulation is adjacent, and the dome angle of diametric side of body center plate and load plane junction, and energy and bevelled side cutting edge overlap joint.By moving up and down of movable tool rest, change the distance between milling cutter fovea superior arc edge and the following dome arc cutting edge, just can adapt to the processing of the cartridge of different depth or height.Press the axis direction and the circumferencial direction of milling cutter at the milling cutter cutter and arrange, the same cutting position of the circumferencial direction of milling cutter has a slice blade at least, has a movable tool rest on the milling cutter at least.
The utility model is compared with prior art: owing to adopt movable tool rest moving up and down, and moving up and down by movable tool rest, change the distance that goes up on the milling cutter between arc edge and the following arc edge, just can adapt to the processing of the cartridge of different depth or height.Changed the drawback that currently used cartridge milling cutter can only be processed the prototype cartridge.
