Description
Technical field
The present invention relates to the endless-rotating cutter sweep in plasma or flame cutting field, what be specifically related to that a kind of cutting head can endless-rotating is wound around underdriven pair of parallelogram endless-rotating groove cutting head of problem without pipeline.
Background technology
At present for the cutting head that carries out the cutting of full circle swinging groove on cutting machine, according to the feature of its deflection and slew gear device, can be divided into and cut tool beat and add the end and drive or push up the revolution of driving, with the end of certain angle, drive beat and add top refoulement and turn and push up three kinds of forms of two parallelogram sturcutres of driving.Below the feature of the cutter head device of these three kinds of forms is described respectively.
One, cut tool beat and add the end and drive or push up the revolution of driving, its advantage is the groove state in the time of directly reflecting cutting, and its beat value and gyration values can intuitively reflect the bevel angle of current cutting and the angle of rotation; But that its shortcoming is mechanism's weight is large, beat axle drives inconvenience, slew gear can cause being connected to the cable and the tracheae that cut tool and be wound around, so control system takes and engrave the rotating number of turns, needs to turn round when the rotating number of turns reaches certain value.In cutting process, can often stop and carry out the reset rotation of gyroaxis, affect cutting efficiency.Bring not inclined to one side also to the programming of digital control system and package software simultaneously.
Two, with the end of certain angle, drive beat and add top refoulement and turn, its advantage is that mechanism structure is compact, and lightweight, cutting accuracy is better; But its shortcoming is beat and rotating value and actual value need to convert, and can not intuitively reflect the bevel angle of current cutting and the angle of rotation, revolution can cause being connected to the cable and the tracheae that cut tool and be wound around.
Three, two parallelogram sturcutres of driving of top, its advantage is that two deflection mechanisms have been avoided being connected to and cut the cable of tool and the problem of tracheae generation winding, its beat value and gyration values can intuitively reflect bevel angle and the rotating angle of current cutting; But the drive form of its shortcoming Shi Ci mechanism is equal in itself on a set of deflection mechanism basis of the first structure and adds a set of parallel-crank mechanism again, its mechanism arrangement volume is huge especially, overall weight is large, increased the bearing capacity of whole cutting machine, it promotes with walking mechanism and all needs to strengthen, need larger driving force, consume the more energy.The structure of whole cutting machine need be strengthened guaranteeing rigidity and precision, causes the cost of whole mechanism high, and marketing is caused to certain difficulty.
