The recording-return spinning machine mandrel data collecting device comprises a transverse oil cylinder, a transverse spinning wheel base and a transverse spinning wheel. A first end of a pipe for communicating two cavities of the oil cylinder is connected with a rodless cavity of the oil cylinder through a first enabling valve, a second end of the pipe for communicating the two cavities of the oil cylinder is connected with a rod cavity of the oil cylinder through a second enabling valve, and a third end of the communicating pipe is connected with a high-precision proportional pressure reducing valve. The recording-return spinning machine mandrel data collecting device has the advantages that the structure is novel, the pressure applied on parts by the spinning wheel is sensed and controlled and is adjusted at any time during mandrel data collection, the key technology of mandrel observe recording, reserve recording and mixed recording is achieved, and the problem that the surface of the spinning machine recording mandrel is damaged is solved.
Description
Technical field
The utility model belongs to the device of playback spinning machine core data acquisition.
Background technology
Spinning is the resultant movement of feed by means of instruments such as spinning rollers, stresses on the metal blank that rotates with the lathe main shaft, makes it produce continuous local plastic deformation and becomes a kind of few without cutting technology of required hollow revolving parts.The effect of the many kinds of forces such as the deformation process more complicated of spinning, material internal are drawn, pressed, shearing, technological parameter is the key factor that affects spinning spare quality.General to revolve part various in style, complex-shaped, and spinning process is complicated and changeable, and deformation extent differs larger everywhere, and material thickness variation is obvious, and its Changing Pattern is difficult to expect and control.
Moulding scheme is in the past mainly leaned on experience, and often needs repeatedly to adjust, and for the workpiece technique of complicated shape, need by a large amount of tests and experience to grope.The playback technology is a kind of special Numeric Control Technology, i.e. teaching is reproduced, and on spinning machine, exploitation playback control technology is a global difficult problem.The difficult point of applying on spinning machine is that core records, and spinning roller is the cutter of rotary pressing processing, has very high hardness, and the spinning force of spinning machine is the hundreds of kilogram at least, and tens tons at most, accurately to record the core curve especially crucial in the situation that do not damage core.Spinning roller is in the mandrel surface Continuous Contact and record complete core curve, but can not be to the mandrel surface injury, some part outer surface is bent shape of generatrix, spinning roller is in the course of the work, the path of experience " upward slope descending ", it is enough little that this just requires that this process contact power will control.
The playback spinning machine is when gathering the core data both at home and abroad, control technology falls behind, often rest on the profiling stage, can't effectively control the spinning roller centripetal force to the core degree that sustains damage in the process of recording the core data, be difficult to meet the demand of complicated spinning process.
Summary of the invention
The utility model provides a kind of harvester of playback spinning machine core data, to solve when spinning machine is recorded mandrel surface the damage problem that exists.
the technical scheme that the utility model is taked is: cylinder piston rod is slidably connected in the horizontal oil cylinder of the horizontal spinning roller of driving spinning machine, be divided into oil cylinder rodless cavity and cylinder rod chamber in this horizontal oil cylinder, the oil cylinder oil inlet pipe is connected with oil cylinder rodless cavity, the oil cylinder oil return pipe is connected with cylinder rod chamber, cylinder piston rod is fixedly connected with horizontal rotary wheel base, laterally spinning roller is rotationally connected with horizontal rotary wheel base, the first end of oil cylinder two chamber cross over pipes is through making energy threshold one be connected with oil cylinder rodless cavity, the second end of oil cylinder two chamber cross over pipes is through making energy threshold two be connected with cylinder rod chamber, the 3rd end of cross over pipe is connected with the high accuracy proportional pressure-reducing valve.
High-performance ratio pressure-reducing valve described in the utility model is reduced to 0. 5 ~ 1bar with oil cylinder working-pressure.
The horizontal rotary wheel base of the utility model spinning machine is fixed on longitudinal axis, can move with longitudinal axis, and laterally spinning roller adopts hydraulic driving mode, introduces the hydraulic structure that differential hydraulic oil cylinder and high accuracy proportional pressure-reducing valve form; Adopt high limit relay that this circuit pressure is reduced to 0.5 ~ 1bar, guarantee that spinning roller can make again the pad pasting amount of overcoming little by pad pasting.For this reason, utilization singly goes out the rod oil cylinder difference in areas to be stretched out oil cylinder or retracts, and is equivalent to hydraulic spring grease cup, and spinning roller is fitted in mandrel surface all the time,, along with the feeding of vertical oil cylinder, completes and records the core curve, to guarantee that oil cylinder can independently advance stably.
The utility model has the advantages that novel structure, when gathering the core data, perception and control spinning roller are applied to the pressure on part and adjust at any time.Broken through core and just recorded, instead record, mix the record key technology, solved spinning machine and recorded the difficult problem of mandrel surface damage.Make lathe can be as manual spinning workman the perception spinning force,, according to thickness and the shape capable of automatic regulating gap of part, more meet the demand of complicated spinning process, be applicable to research and the process program experiment of spinning machine processing technology.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Described high-performance ratio pressure-reducing valve is reduced to 0. 5 ~ 1bar with oil cylinder working-pressure.
the horizontal rotary wheel base of spinning machine is fixed on longitudinal axis, can move with longitudinal axis, when recording the core data, utilize horizontal hydraulic oil cylinder driving lateral shaft X and drive horizontal spinning roller feeding, for avoiding horizontal spinning roller centripetal force to scratch too greatly mandrel surface, that strength must be controlled is enough little, at this moment, UNICOM's oil cylinder two chambeies on original oil cylinder basis, and near oil cylinder rodless cavity and cylinder rod chamber installation, make energy threshold one and making energy threshold two, add high accuracy proportional pressure-reducing valve 8 in oil cylinder two chamber cross over pipes 7, when spinning machine is recorded the core data, system is controlled and is made energy threshold one and energy threshold two is opened simultaneously, make oil cylinder two chamber UNICOMs, be reduced to 0. 5 ~ 1bar by high-performance ratio pressure-reducing valve with oil cylinder working-pressure this moment, the driving force that can guarantee oil cylinder output can continuously drive horizontal spinning roller to pressing close to the feeding of core direction, can not damage core again, feeding along with vertical oil cylinder, complete and record the core curve.In the situation that normal rotary pressing processing, the specified power output of oil cylinder is 200KN, and system is controlled and made energy threshold one and make energy threshold two shutoffs, and this moment, oil cylinder two chambeies were not communicated with, and guaranteed that oil cylinder drives spinning roller with nominal force, completed the processing of workpiece.
