Abstract
The invention discloses a spindle hood structure for a numerical control electric discharge machining shaping machine. The structure comprises a spindle, a connecting shaft, an outer hood, an inner hood and a fixture, wherein two ends of the connecting shaft are respectively and fixedly connected with the spindle and the fixture; the outer hood is fixed to the outer circumference of the connecting shaft; the inner hood is fixedly arranged at the bottom of the outer hood; the outer circumference of the inner hood and the outer circumference of the outer hood form an inner cavity and an outer cavity which are communicated with each other; a sealing ring is arranged between the bottom of the outer hood and the top of the inner hood; the side wall of the outer hood is provided with an oil inlet communicated with the inner cavity; the connecting shaft is hollow, a smoke collecting cavity is formed in the connecting shaft, the lower part of the side wall of the connecting shaft is provided with a smoke inlet, and the upper part of the side wall is provided with a smoke outlet; the smoke inlet is communicated with a smoke guiding cavity and the smoke collecting cavity which are positioned at the bottom of the inner hood; in the machining process of the electric discharge machining shaping machine, an oil curtain generated by the structure seals a machining area, waste gas generated in the machining process is discharged through the smoke outlet under the guide of a smoke inlet cavity, harmful gas is collected and filtered, and the harm to environment and human bodies is reduced to achieve environmental friendliness.
Description
Technical field
The invention belongs to numerical control and manufacture field, particularly relate to a kind of edm forming main shaft of numerical control machine tool hood structure.
Background technology
Spark erosion technique becomes one of important manufacturing process of Modern Manufacturing Technology with the process principle of its uniqueness and good, stable processing characteristics.It is distinctive " defeat a force with a tenderness, closely fine, profiling is true to nature " three large features, extremely important status is occupied in the manufacture fields such as unmanageable material, complex profile, fine surface, Low rigidity part and mould, through the development of over half a century, the fields such as Aero-Space, instrument and meter, automobile, geology are widely used in.
Because the smog produced in Electric Discharge Machining is not only to air and environment, also can to the healthy adverse influence of human body.Therefore the present invention considers from environmental protection and to the safety problem of human body, devises main spindle hood of electric spark moulding machine, for collecting the waste gas produced in processing, reduces the harm to environment and human body.
Summary of the invention
The object of the invention is to the deficiency for producing in Electric Discharge Machining the gas that environment and human body are harmful to, a kind of numerical control electric spark molding machine main shaft hood structure is provided.
The present invention's adopted technical scheme that solves the problem is: a kind of numerical control electric spark molding machine main shaft hood structure, and it comprises: main shaft, connecting axle, outer cover, inner cover and fixture; Wherein, the two ends of described connecting axle are fixedly connected with fixture with main shaft respectively, outer cover is fixed on the excircle of connecting axle, inner cover is fixed on shield base, the excircle of inner cover and the inner periphery of outer cover form the inner chamber and exocoel that communicate jointly, between the bottom and the top of inner cover of outer cover, be equipped with sealing ring; The sidewall of outer cover has the oil-in communicated with inner chamber; Connecting axle hollow, inside is smog collecting chamber, and lower sidewall has into mouth, and side wall upper part has exhaust opening, enters the smog guidance cavity bottom mouth connection inner cover and smog collecting chamber.
The invention has the beneficial effects as follows: the present invention is by a kind of novel numerical control main spindle hood of electric spark moulding machine structure, in the process of electric spark shaping mill, the oil curtain utilizing this mechanism to produce closes machining area, make the waste gas produced in processing under the guiding of smoke input chamber, discharged by outlet flue, realize the collection to pernicious gas and filtration, reduce the harm to environment and human body, reach environmental protection.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present invention;
In figure, main shaft 1, connecting axle 2, sealing ring 3, outer cover 4, inner cover 5, fixture 6, smog collecting chamber 7, enter mouth 8, smog guidance cavity 9, exocoel 10, oil-in 11, inner chamber 12, exhaust opening 13.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, numerical control electric spark molding machine main shaft hood structure of the present invention comprises: main shaft 1, connecting axle 2, outer cover 4, inner cover 5 and fixture 6.The two ends of connecting axle 2 are fixedly connected with fixture 6 with main shaft 1 respectively by bolt, outer cover 4 is bolted on the excircle of connecting axle 2, inner cover 5 is bolted on bottom outer cover 4, the excircle of inner cover 5 and the inner periphery of outer cover 4 form the inner chamber 12 and exocoel 10 that communicate jointly, are equipped with sealing ring 3 between the bottom of outer cover 4 and the top of inner cover 5.The sidewall of outer cover 4 has the oil-in 11 communicated with inner chamber 12.Connecting axle 2 hollow, inside is smog collecting chamber 7, and lower sidewall has into mouth 8, and side wall upper part has exhaust opening 13, enters mouth 8 and is communicated with smog guidance cavity 9 bottom inner cover 5 and smog collecting chamber 7.
As shown in Figure 1, in the process of Electric Discharge Machining, oil pump by fluid from each one of oil-in about 11() squeeze into inner chamber 12, inner chamber 12 reduces gradually, fluid cushioned and improves its flow velocity, then from the osculum between inner cover 5 and outer cover 4, flowing into exocoel 10.Fluid cushions after entering exocoel 10 further, and finally in the gap that inner cover 5 and outer cover 4 are formed, along cover wall with the ejection of certain angle, form oil curtain, oil curtain covers the area of space of hood to workbench from top to down, is covered in oil curtain by electric discharge machining area.The smog that processing produces, under the guiding of smog guidance cavity 9, entering after smog collecting chamber 7 collects by entering mouth 8, by outlet flue 13 sucking-off, after subsequent filter device filters, entering air.
In the process of electric spark shaping mill, the oil curtain utilizing the present invention to produce closes machining area, the waste gas produced is discharged by outlet flue 13, realizes the collection to pernicious gas and filtration, reduce the harm to environment and human body, reach environmental protection in processing.
