Description
Technical field
What the present invention relates to is a kind of burning torch mechanism that becomes born of the same parents' characteristic that has that is used for the major diameter NC flame cutting machine.
Background technology
In the shipbuilding process, usually run at large cylindrical surface of shell cutting large size circular hole, simultaneously the angle of release degree continually varying situation of groove up and down on the hole.According to process requirements, cutting mechanism should have two main cutting functions: the one, can finish cutting large size circular hole on cylindrical shell, and the 2nd, can in institute's perforate, cut the varied angle groove.And directly exist cut state to change between mouthful cutting and the groove cutting, different to the duty requirement of cutting machine.When processing straight mouthful, require burning torch in perpendicular, to work; During finished edge, burning torch adapts to the constantly swing in vertical plane of different bevel angles.
At present, the solution to this problem mainly contains:
1, adopts special-purpose burning torch
Vertical burning torch is adopted in straight mouthful of processing, and swing burning torch (Hu Shenghai etc. " evolution of swing mechanism and design in the NC flame cutting machine ") is adopted in groove processing.When two kinds of cut states are switched, change burning torch.Burning torch is with strong points, and the cut quality height can produce inconvenience but need to change burning torch.
2, adopt parallel institution to form burning torch
Adopt the motion of parallel institution control burning torch.During straight mouthful of cutting, burning torch moves to the upright position; During the groove cutting, the parallel institution motion makes burning torch change swing (Lv Jinli " design of serial parallel mechanism and emulation in the complex-curved cutting machine ") by bevel angle.There is not the trouble of changing burning torch in the method, but the control of parallel institution is complicated.
Summary of the invention
The object of the present invention is to provide a kind of major diameter NC flame cutting machine that adapts to the demand of straight mouthful of cutting and groove cutting to become born of the same parents' burning torch mechanism.
The object of the present invention is achieved like this:
By changeing bridge, installing rack, connect the support that changes bridge and installing rack, be fixed on the motor cabinet on the installing rack, be installed on the leading screw drive motors on the motor cabinet, leading screw by the spindle motor driving, with the leading screw nut engaged, being installed on being used on the installing rack limits the chute gland that nut slides, be used to support the leading screw bracing frame on leading screw top, connecting rod, the thread spindle that connects connecting rod and nut, the gland of the position of bearings of restriction thread spindle on connecting rod, be installed on the arc plate drive motors on the installing rack, be connected the arc plate on the arc plate drive motors, the clamping plate that can in the arc plate, slide by the connecting rod drive, be installed on the roller that is used to guarantee the clamping plate circular motion on the arc plate, be used on clamping plate the fixedly geometrical clamp of burning torch position, the burning torch of the clamping that is fixed on clamping plate formed.
Form the swing free degree by motor cabinet, leading screw drive motors, nut, thread spindle, gland, connecting rod, clamping plate, roller, arc plate.
Form the change born of the same parents free degree by arc plate drive motors and arc plate.
Form the fixedly fixture of burning torch position by geometrical clamp, clamping plate.
The operation principle of patent of the present invention is:
In the time of between directly mouth cutting and groove cut, there are 2 frees degree in mechanism: by the change born of the same parents free degree of arc plate drive motors driving, by the swing free degree of feed screw nut driving.Become born of the same parents mechanism when directly changing between mouthful cutting and groove cutting, fixed position release when the change born of the same parents free degree is cut by groove, become born of the same parents' free degree and form 5 linkages with the swing free degree, burning torch is adjusted to straight mouthful of Working position (burning torch vertically), and the swing free degree was all fixed with the change born of the same parents free degree after burning torch arrived vertical position.
The groove cutting becomes born of the same parents' free degree and is consolidated in the groove cutting position, and entire mechanism is swung 1 free degree mechanism for 4 bars after developing.Under the driving of spindle motor, nut moves along the slideway on the installing rack, by being fixed in the thread spindle drivening rod on the nut, driving clamping plate and swings along the slideway on the arc plate, adapts to the varied angle requirement that groove adds man-hour.
Straight mouthful of cutting, the burning torch direction requires vertically.Become born of the same parents' free degree from fixed groove cutting position release, the swing free degree with become born of the same parents' free degree and form 5 bar 2DOF mechanisms, it is all locked that burning torch is moved to behind the vertical position.
The present invention has explored a kind of change born of the same parents burning torch mechanism that the major diameter NC flame cutting machine is realized straight mouthful of groove processing conversion that is used for.Be used to satisfy the requirement of straight mouthful of major diameter NC flame cutting machine processing and groove.Become born of the same parents mechanism, there is variation in mechanism's topological structure in entire work process, can satisfy such requirement by the reconstruct of mechanism self according to different environment and working condition requirement.The present invention adopts has the burning torch mechanism that becomes born of the same parents' characteristic, has that processing is with strong points, quality is high, controls simple advantage simultaneously.
