Description
One, technical field
The present invention relates to a kind of swivel joint of lathe, be mainly used in the milling machine tool working of machining optical element, ceramic component.
Two, background technology
In the milling process of optical element, ceramic component and other non-metal workpiece, a large amount of diamond-impregnated wheels that use, in order to keep the cutting force of emery wheel, to add the chemicals with the bronze bonding agent function of corrosion in cooling fluid, along with bonding agent is corroded, diamond particles also constantly is shed in cooling fluid, although cooler bin has adopted centrifugal filtration, but the particle that still contains certain density bortz powder, glass dust, ceramic powder in cooling fluid, very short time cooling fluid just become grinding fluid.Glass, ceramic component milling for diameter D 〉=70mm, because the emery wheel rotating speed is high, if the burn phenomenon occurs in the cooling not enough meeting of part to be processed, only rely on the multichannel of part outside to spray not enough cooling, the grinding head shaft of rotation also must be made hollow-core construction, make grinding fluid can enter by grinding head shaft the inside machining area of emery wheel, the spray type of cooling in Here it is, to pass through cooling fluid in the grinding head shaft of rotation, produce wrapping phenomena for avoiding the outer carrier pipe road to rotate with the axis, just must install swivel joint additional.Swivel joint of the prior art generally adopts the balanced type hermetically-sealed construction, sees Fig. 1, and it is by rotating part I, and non-rotating part II, intermediate seal loop section III and spring section IV form.Balanced seal relies on external springs pressure to seal in swivel joint inside exactly, and the operating pressure of medium is smaller on the impact of sealing, flat seal normally, and two contact-making surfaces use spring compression by wear-resistant tungsten carbide made.Sealing ring is the main consumable accessory of swivel joint; when operation; sealing ring not only bears the frictional force that inner ring plate relative motion produces; but also to bear frictional force from outer tube and housing; if containing similar glass dust, bortz powder etc., the liquid medium that passes through has particle than heavy-duty grinding power; the wearing and tearing of tungsten carbide ring are very fast; in short time, drainage will appear; the cooling effect of reduction equipment; affect the normal use of equipment, cause shutting down, increasing maintenance and the maintenance cost of equipment.Therefore to produce actual needs in order satisfying, to fill up the blank in this field, is the technical problem anxious to be resolved of pendulum in face of us.
Three, summary of the invention
Main task of the present invention and purpose are under the use state, during by grinding fluid, to exist the hermetically-sealed construction rapid wear according to existing swivel joint, to the defective of milling machine tool working cooling effect decline.Design a kind of one-way high-speed rotating joint of novel transmitted grinding fluid.Fundamentally overcome hermetically-sealed construction rapid wear, the poor phenomenon of cooling effect, effectively improve and guarantee cooling quality and the service life of swivel joint.
Main technical schemes of the present invention: the structure of swivel joint is, a, rotating part, on the top external cylindrical surface of trapping, an accurate self-aligning ball bearing is housed, match with the endoporus of lower house in the outer ring of self-aligning ball bearing, to the endoporus of upper shell, two rubber framework grease seals have been installed above bearing, sealing ring 8 is equipped with in the bottom of trapping; B, non-rotating part, upper shell and lower house link together by four uniform soket head cap screws; C, annular seal space part, insert in the endoporus of trapping the lower end of upper cover, three sealing rings are housed on microcephaly's external cylindrical surface of upper cover, match with 6 the endoporus of trapping and form three grades of annular seal spaces, the upper end of upper cover is fixed on upper shell by three soket head cap screws on the one hand, sealing ring is housed, on the other hand by plug-in type angle coupling of thread connection on faying face.
The present invention proves by practical probation: reach the development purpose fully, 1, milling machine tool working in the situation that 4500 rev/mins by grinding fluid, more than continuous operation half a year, seal structure damage do not occur, leak and phenomenon that cooling effect descends.And common swivel joint is when this type of grinding fluid, and general 7 days just begin to occur leaking, and constantly aggravation, can not use about 30 days; 2, the sealing part abrasion repair and replacement are simple, as long as take down support, upper cover just can whole be extracted from trap, and after again changing three sealing rings, just can continue to use during insertion is trapped; 3, obviously increase work efficiency, satisfy modern milling production to the instructions for use of swivel joint.
