Abstract
The utility model belongs to the machine manufacture technology field, and relates to a device for magnetic seal of a sliding door of a high-pressure cooling protective cover of a grinding machine. The main technical points are that a magnet is arranged on a guide pressure plate; a sliding door is provided with an armature screw which is corresponding to the magnet on the guide pressure plate; and a door frame on a protective cover body, a seal backing plate and the guide pressure plate have a concentric-circle shape. The device of the utility model is simple in structure, low in manufacture cost and quite good in sealing effect. The sliding door is sealed and is not prone to liquid leakage when closed, and is easy to open and close. In addition, the operation and the application are convenient, flexible and labor-saving, thereby greatly reducing the labor intensity for workers.
Description
One, technical field
The utility model relates to a kind of sliding door sealing device, and specifically a kind of grinding machine high pressure cooling protective cover sliding door magnet sealing device belongs to machinery manufacturing technology field.
Two, background technology
Modern grinding machine high speed, efficient, deep, creep feed grinding, it is big to produce heat, destroys the metallographic structure on work piece top layer easily; Even burn surfaces, the burn emery wheel has only the cooling of configuration high pressure; Force the spirt emery wheel to rotate the grinding area that produces powerful air pressure at a high speed cooling fluid, wash away the heat that grinding produces, wash away the abrasive dust that is bonded on the emery wheel; It is sharp that emery wheel is kept clean, and the assurance grinding is normally carried out, and guarantees that work piece face quality is intact.
The pressure of high pressure cooling is generally all greater than 1Mpa, and jet length can reach tens of rice, and reflective distance also reaches several meters, even tens meters, so being the high-speed grinding high pressure, protective cover cools off requisite parts.Existing protective cover generally is by the protective cover main body, sliding door, and the sealed hair felt rug, compression bar, the adjustment screw is formed.On the protective cover main body, be provided with bistrique installing hole and headstock installing hole.The protective cover main body generally is to be welded with steel plate, and intensity and leakage can reach requirement, and sliding door both should satisfy be prone to out, be prone to close, laborsaving, also do not allow cooling fluid to spill with the periphery that protective cover main body doorframe combines from sliding door.Sliding door is generally all made with lucite, (with adhesive) felt layers is arranged between the doorframe of sliding door and protective cover main body, and compression bar also has (with adhesive) felt layers.Screw scalable compression bar is sliding door and felt layers between them to the distance between the body frame, and sliding door (material lucite) thickness is to change, and the result who regulates (screw) relaxes or compress the thickness of felt layers.Tighten screw in theory and can solve the leakage problem, when in fact tightening the screw no leakage, the push-and-pull of door is required great effort very much; Push-and-pull is flexible basically when laborsaving, and the leakage problem can't solve again.In real work, at first considering can not leakage, and the problem of sliding door folding effort has been hurted the operator bitterly.With XYJ-2003 is example, and about 400 parts are processed in per tour, needs one way to move door 800 times, and the operator's finger of getting off for a long time wrist has all been strained, and this is a urgent problem.
Three, the content of utility model
The utility model is in order to overcome sealing effectiveness and too big this shortcoming of the contradiction that causes of operating physical force in original technology; Prior art is improved; Reach and seal both no leakages when sliding door is closed; The operation that can like a cork sliding door opened, closed again, convenient, flexible, laborsaving, thus a kind of new technical scheme is provided.
For achieving the above object, the utility model can be realized through following technical scheme:
Grinding machine high pressure cooling protective cover sliding door magnet sealing device; It is on the protective cover main body, to slide to be provided with sliding door; Between the doorframe of protective cover main body and guiding pressing plate, be provided with sealed bolster plate; Be provided with trip bolt at doorframe, the sealed bolster plate of protective cover main body and a periphery of the pressing plate that leads, on the protective cover main body, be provided with bistrique installing hole and headstock installing hole.On the guiding pressing plate, be provided with magnet, be provided with armature screw and corresponding on the sliding door with the magnet on the guiding pressing plate.
The front inside casing of protective cover main body, sealed bolster plate and guiding pressing plate all are the Back Word shapes.
The utility model is that the advantage that is had is: simple in structure, cheap for manufacturing cost, sealing effectiveness is very good; When closing, sliding door seals both no leakages; Can like a cork sliding door be opened and closed again, and easy for operation, flexible, laborsaving, can alleviate working strength of workers greatly.
Four, description of drawings
Accompanying drawing 1 is the utility model high pressure cooling protective cover sliding door magnet schematic diagram of sealing device;
Accompanying drawing 2 is that the A-A of the utility model accompanying drawing 1 is to the sectional structure sketch map.
Accompanying drawing 3 is shapes of front inside casing, sealed bolster plate 5 and the guiding pressing plate 6 of jointless protective cover main body 1 all around.
Five, the specific embodiment
Combine accompanying drawing the utility model to be explained further details with specific embodiment at present:
A kind of grinding machine high pressure cooling protective cover sliding door magnet sealing device is seen Fig. 1, Fig. 2, Fig. 3.It is made up of protective cover main body 1, sliding door 2, magnet 3, armature screw 4, sealed bolster plate 5, guiding pressing plate 6, trip bolt 7.
Parts such as the headstock of protective cover main body 1 and grinding machine, bistrique are connected, and fastening, sealing.The shape of the doorframe of protective cover main body 1, sealed bolster plate 5, guiding pressing plate 6 all be three-back-shaped and the neighboring big or small all identical, their are fastening with several trip bolts 7, the material of sealed bolster plate 5 is a rubber, and is flexible, the faying face between them can leakage.Sliding door 2 is to make with the machine glass material.
Here only need to solve the framework leakage partly and the light problem of operation that sliding door 2 combines with guiding pressing plate 6.The thickness of sealed bolster plate 5 is greater than sliding door 2mm, that is: sliding door 2 thick 4mm, sealed bolster plate 5 thick 6mm.Like this, sliding door 2 is in the groove that doorframe, sealed bolster plate 5, the guiding pressing plate 6 (fastening with trip bolt 7) of protective cover main body 1 are formed, and all there is the gap of 2mm all around, and moving of sliding door 2 is very flexible.There is the gap in the time of mobile flexible, can leakage.But sliding door 2 usefulness lucite are processed, and the surface is very flat, the guiding pressing plate 6 also process surfacing with lucite, when they contact, if a power is arranged, make they each other near the time, cooling fluid also can't spill from its bonding crack.4 magnet 3 of 4 angles edges of joint when sliding door 2 and guiding pressing plate 6 closures are being provided with armature screw 4 and corresponding with the magnet 3 on the guiding pressing plate 6 again on the sliding door 2.Armature screw 4 is selected 90 ° of sunk screws for use; Head of screw is towards magnet 3, and the head of armature screw 4 is lower than sliding door 2 surfaces 0～0.05mm, like this in sliding door 2 closed positions; Utilize 4 magnet 3 to attract the power of armature screw 4 that sliding door 2 and doorframe are compressed, realized sealing.When opening sliding door 2, as long as impose on the contrary with magnet 3 gravity directions at handling position, strength is greater than magnet 3 attractions, and door will leave, and nature glides along groove and opens under the gravity effect.When sliding door 2 was closed, the gravity that only need overcome sliding door 2 is put on the closed position with sliding door 2 along groove, and was closed naturally under the attraction force acts of magnet 3.
