Description
Technical field
The utility model relates to a kind of deep hole processing method, particularly relates to a kind of deep-hole drilling machine electrohydraulic servo system.
Background technique
Deep-Hole Drilling Technology may be defined as: use the cooling-lubricant of certain pressure and chip removal system, adopts the good deep hole tools of guiding, lathe and effectively can control the additional device of its processing stability, reach the object of efficient, high-precision deep hole processing.At present, the deep hole processing mode adopting traditional permanent feeding of pure machinery in actual applications more, but due in gun drilling process, there is multifactorial interference perhaps, the value of drill thrust in very large range can be changed, thus occur that overload phenomenon causes the longitudinal bending of drill bit, skew, even fractures.If in drilling process, effective control can be made to drill thrust, then fundamentally can avoid the generation of above-mentioned phenomenon.With regard to deep hole processing mode, there are multiple choices.Consider the performance requirements such as system is exerted oneself greatly, high response, high stability, Hydraulic servo technology can be adopted to realize deep hole processing.In order to improve the stability of machine cut, except taking certain methods to improve except the performance of lathe when machine tool design, manufacture, also in machine cut process, must achieve the goal by doing corresponding control on the cutting parameter affecting machine stability thus ensureing that cutting torque is constant.When aperture is certain, the size of drilling torque be controlled, must the amount of feed be controlled.
Summary of the invention
In order to improve the stability of machine cut, the utility model provides a kind of deep-hole drilling machine electrohydraulic servo system, it is characterized in that: comprise oil hydraulic pump, servoamplifier, electromagnetic relief valve, pressure gauge, cooler, solenoid directional control valve, drill bit, oil hydraulic motor, electrohydraulic control, oil hydraulic cylinder, described servoamplifier, electrohydraulic control, oil hydraulic cylinder is connected to form control system successively, described pressure gauge, electromagnetic relief valve is connected with oil hydraulic pump, described oil hydraulic pump, solenoid directional control valve, oil hydraulic motor, drill bit connects successively, piston rod on described oil hydraulic cylinder connects the worktable at drill bit place, described cooler is connected in the return line of oil hydraulic motor and oil hydraulic pump composition.
The beneficial effects of the utility model are: adopt the mode of electro-hydraulic servo control, by the control of the amount of feed indirectly to control the change of drilling torque, thus improve the stability in gun drilling process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, oil hydraulic pump, 2, servoamplifier, 3, electromagnetic relief valve, 4, pressure gauge, 5, cooler, 6, solenoid directional control valve, 7, drill bit, 8, oil hydraulic motor, 9, electrohydraulic control, 10, oil hydraulic cylinder.
As shown in Figure 1, described servoamplifier 2, electrohydraulic control 9, oil hydraulic cylinder 10 are connected to form control system successively, described pressure gauge 4, electromagnetic relief valve 3 are connected with oil hydraulic pump 1, oil hydraulic pump 1 is connected successively with solenoid directional control valve 6, oil hydraulic motor 8, drill bit 7, piston rod on described oil hydraulic cylinder 10 connects the worktable at drill bit 7 place, and described cooler 5 is connected in the return line of oil hydraulic motor 8 and oil hydraulic pump 1 composition.
Final controlling element is the oil hydraulic motor 8 driving drill bit 7 to rotate and the oil hydraulic cylinder 10 driving worktable to retreat; The oil sources of system is quantitative hydraulic pump 1, and the charge oil pressure of pump and off-load are controlled by electromagnetic relief valve 3, and pressure can be shown by pressure gauge 4 and switch thereof; The oil-feed of oil hydraulic motor 8 is controlled by two-position four-way solenoid directional control valve 6; The total return line of system is provided with cooler 5, for the heat radiation of system fluid.
After system starts, electromagnet 1YA is energized, and oil hydraulic pump 1 transfers boosting to by off-load and supplies oil condition to oil hydraulic motor 8 and oil hydraulic cylinder 10 simultaneously.Electromagnet 2YA energising makes solenoid directional control valve 6 switch to right position, and the pressure oil of oil hydraulic pump 1 enters the pumping cavity of oil hydraulic motor 8 through selector valve 6, oil hydraulic motor 8 drives drill bit 7 to rotate.Meanwhile, electromagnet 4YA energising makes selector valve switch to right position, and the pressure oil of oil hydraulic pump 1 enters the rodless cavity of oil hydraulic cylinder 10, and piston rod drives worktable to advance fast; When the buting iron being fixed on slide front end touches position limit switch, by regulating the opening amount of electrohydraulic control 9, make piston rod become work at a slow speed and enter, lathe enters the drilling stage.After workpiece has bored hole, electromagnet 3YA energising makes selector valve switch to left position, and the pressure oil of oil hydraulic pump 1 enters the rod chamber of oil hydraulic cylinder 10, make piston rod together with worktable rapid backward, when the buting iron of sliding base rear end touches position limit switch, then retreat stopping, drill bit 7 also stall.
In drilling process, the major requirement of system is that work enters process control, and principle is: according to the requirement of processed piece, calculates the moment of torsion needed for drill bit 7 by certain rule, and control the opening amount of electrohydraulic control 9 with this signal, thus carry out the amount of feed of regulator solution cylinder pressure 10.Now, by the moment of torsion suffered by drill bit 7 compared with Setting signal, deviation signal is drawn.This deviation signal is input to electrohydraulic control 9 after servoamplifier 2 amplifies, electrohydraulic control 9 is made to produce load differential pressure action on the piston of oil hydraulic cylinder 10, make moment of torsion to the direction change reducing error, equal the value of command signal defined until moment of torsion till by the amount of feed changing oil hydraulic cylinder 10.
Be described in detail of the present utility model by embodiment above, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
