Abstract
The utility model discloses a high-speed electric spark apparatus for processing a deep hole. The high-speed electric spark apparatus is an accessory arranged on a general electric spark forming machine tool. The high-speed electric spark apparatus adopts high pressure oil as working solution. The high-speed electric spark apparatus designs a high sealed electrode clamp which is rotatable. The utility model has the advantages of high precision, high work efficiency, low cost and high precision. An original general electric spark forming machine tool can process hard-to-cut material and a deep hole with high speed, for example, a hard alloy can be processed. When the diameter of an electrode is phi 1 (mm), the processing depth is 20 (mm), the working speed is 2-3 mm/min in average, and the accuracy is 0.1 (mm). The field of application for a machine tool is expanded.
Description
The utility model is a kind of annex of adapted on general Electric Discharge Machining lathe, it has the lathe of expansion range of application, make general Electric Discharge Machining lathe can carry out the dark aperture High-speed machining of difficult-to-machine material, can improve work efficiency, played the effect of one-machine-multi-function.
Continual renovation along with science and technology development and product, the application of carbide alloy, pure tungsten, titanium alloy etc materials more and more widely, and many new product parts all relate to dark aperture processing problems, but the dark aperture processing of hard material for a long time is a great problem in the manufacturing process always, " general electric spark machine tool processing rigid material and dark aperture efficient, precision are very low; when hole depth with the ratio in aperture greater than 20 the time, just can't process at all." at present both at home and abroad to the dark aperture of hard material; generally all adopting water under high pressure to make the working solution copper pipe is electrode; process with high current density, and also having a kind of employing in addition is the compound working solution of base and special pulse current with water, and difficult-to-machine material is carried out the dark aperture processing of high speed.But this all needs to change the working solution of original general EDM shaping machine.And need task equipment, can not utilize existing lathe, so cost is higher.The utility model is at above-mentioned difficulties, designed a kind of annex of special processing usefulness, under the condition that does not change former kerosene working solution and the existing lathe main process equipment of utilization, make original general Electric Discharge Machining lathe, the more conventional spark machined of production efficiency improves 10～15 times, realized the dark aperture rapid processing of difficult-to-machine material, and it is with low cost, easy and simple to handle.
Solution of the present utility model is: the annex of a special processing usefulness of design, it has a rotatable electrode chuck, guarantees that hollow edged electrode has very high clamping location and running accuracy, but also will guarantee favorable conductive and logical oiliness energy.Outside electrode, guiding mechanism is housed so that guarantee that electrode is accurate in the axis displacement of feeding process, reduces the vibration of electrode in process simultaneously.Adopt the high-pressure work fluid circulation in addition, to improve the chip removal ability.Simultaneously according to machined material, aperture and with the ratio of the degree of depth, adopt suitable electrical quantity.Obtain good technological effect.
Fig. 1 is the profile of this annex.
Fig. 2 is its side view.
Below in conjunction with Fig. 1, Fig. 2 is described further the utility model:
This annex mainly is made up of body (Fig. 1,1. extremely 7. forming among Fig. 2) and guider (Fig. 1,9. and 10. forming among Fig. 2).1. be connected body, in order to join with machine tool chief axis, can make is taper shank or ring flange, 2. is the feed flow cavity, 3. is rotary main shaft, 4. being the hydraulic oil seal, 5. is decelerator, 6. is driving motor, 7. is collet, 8. being pipe electrode, 9. is fairlead, 10. is holder, and (11) are guide pillar.After 1. connected body installed with machine tool chief axis, 2. liquid-supplying system fed the feed flow cavity with hydraulic oil.Since the sealing function of hydraulic oil seal force hydraulic oil by rotary main shaft centre bore 3. from 0 entering hollow edged electrode 8. shown in Fig. 1 arrow.Decelerator 5. with 6. driven rotary main shaft and pipe loading electrode rotation of driving motor.Collet guarantees the electrode positioning accuracy 7. as the self-centering element, reduces electrode deformation again.10. 9. fairlead be connected with holder with the conical surface, and holder is connected with reducer shell with (11) guide pillar of two precisions, to realize that electrode is accurate in the axis displacement of feeding process, reduces vibration in the processing.
