Abstract
The invention discloses a deep hole machining device, which comprises an electrolyte tank, a high-pressure liquid pump, a cathode, an insulating tube and a power source, wherein the output end of the electrolyte tank is connected with the input end of the high-pressure liquid pump; the output end of the high-pressure liquid pump is connected with the insulating tube; the cathode is arranged in the insulating tube, and is connected with the input end of the power source; and the output end of the power source is connected with a workpiece. By the device, electrolyte with certain pressure flows through a tool electrode and the workpiece at a high speed and washes away an electrolysate dissolved from an anode, and a deep hole is directly formed through one-time feeding, so the production efficiency is high. The device is compact in structure, ensures that a machined surface does not have any residual stress, fins, burrs, degenerative layers and the like, can machine metal materials with any hardness, strength and toughness, and is high in surface roughness and machining accuracy.
Description
Technical field
The present invention relates to a kind of deep hole drilling apparatus.
Background technology
At present, like the axial oilhole of oil har opening, axle, the gun tube of rocket bomb body and various cannons etc., the deep hole of aspect ratio L/d >=100 adds man-hour.Because the cutter radiating condition is poor, difficulty is discharged in smear metal, causes cutting temperature to raise, and the durability of cutter is reduced; And higher because of the machining accuracy and the surface quality that require, the machinability of the machined material that has is relatively poor, usually becomes a great problem in the production; Therefore, when producing, knife bar often receives the restriction in aperture; Diameter is little, and length is big, makes chip removal difficult; Cause poor rigidity easily, intensity is low, and the vibration that produces during cutting, ripple, tapering have all influenced the linearity and the surface roughness of deep hole.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of compact conformation in order to solve the deficiency of prior art, high efficiency, and machining accuracy and surface roughness are good, the deep hole drilling apparatus that tool electrode loss is little.
Technical scheme: in order to realize above purpose, a kind of deep hole drilling apparatus of the present invention, it comprises the electrolyte case; The high pressure liquid pump, negative electrode, insulation tube and power supply; The output of described electrolyte case links to each other with the input of high pressure liquid pump, and the high pressure liquid delivery side of pump links to each other with insulation tube, is provided with negative electrode in the described insulation tube; Described negative electrode links to each other with the input of power supply, and the output of power supply links to each other with workpiece.
Be provided with electrolyte in the described electrolyte case.。
Beneficial effect: a kind of deep hole drilling apparatus provided by the invention, the electrolyte that will have certain pressure flows through between tool-electrode and workpiece at high speed, and washes away the electrolysate that dissolves on the anode; Through primary feed, direct forming is so production efficiency is high; This apparatus structure is compact; Make finished surface not have residual stress and overlap, burr, metamorphic layer etc., can process the metal material of any hardness, intensity, toughness, and surface roughness and machining accuracy are high.
Description of drawings
Fig. 1 is an operation principle sketch map of the present invention.
The specific embodiment
As shown in Figure 1, a kind of deep hole drilling apparatus of the present invention, it comprises electrolyte case 1, high pressure liquid pump 2, negative electrode 3, insulation tube 4 and power supply 5.
The output of described electrolyte case 1 links to each other with the input of high pressure liquid pump 2, and the output of high pressure liquid pump 2 links to each other with insulation tube 4, is provided with negative electrode 3 in the described insulation tube, and described negative electrode 3 links to each other with the input of power supply 5, and the output of power supply 5 links to each other with workpiece 6.
Be provided with electrolyte in the described electrolyte case 1.
Because of workpiece density is different with the instrument as electrode with surface configuration, each point is also just different with the distance of tool surfaces on the workpiece, and the current density that the place of close together is passed through is bigger; The tasselled of electrolyte are also higher, and the rapid speed of anodic solution is opposite; The place that distance is far away, current density is just little, and the flow velocity of electrolyte is just slower; Anodic solution speed is just slow, and when starting high pressure liquid pump 2, the electrolyte in the electrolyte case 1 flows through insulation tube 4 through high pressure liquid pump 2; With at a high speed ejection, form the electrolyte a fluid stream, when electronegative electrolyte high velocity jet to 6 last times of workpiece; Spray site produces anodic solution on the workpiece 6, and processes dark aperture along with the continuous feeding of negative electrode 3.
The electrolyte that this device will have certain pressure flows through between tool-electrode and workpiece at high speed, and washes away the electrolysate that dissolves on the anode, through primary feed; Direct forming; So production efficiency is high, this apparatus structure is compact, makes finished surface not have residual stress and overlap, burr, metamorphic layer etc.; Can process the metal material of any hardness, intensity, toughness, and surface roughness and machining accuracy height.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection of the present invention.
