Certain installation protective effect is played in entire numerically-controlled machine tool, the clast generated when work of numerical control machine and cooling is avoided to use
Aqueous be splashed to and make observer's body, reduce the humidity of numerically-controlled machine tool observer's clothing and be cut clast scuffing
Situation, but the protective door structure of existing market is simple, after long-time use, frictional force increases in sliding process, causes to protect
Door sliding is slow, and noise increases when sliding, is unfavorable for building the workshop condition of high quality, and the aqueous used that cools down is easy attachment
Observation glass surface in the middle part of protective door causes glass surface fuzzy so that observer cannot be effectively by observing glass
Observe the working condition of numerically-controlled machine tool, it is difficult to find the unexpected situation in cutting process in time and stop numerically-controlled machine tool work in time
Make, causes the damage of cutting tool and workpiece, in order to avoid protective door side wall direct collision to fuselage, existing protective door side wall
Rubber sheet gasket can be installed, but such rubber sheet gasket is difficult to effectively remove after damage, while the installation of rubber sheet gasket
Journey is comparatively laborious, is unfavorable for quick-replaceable to ensure that protective door can be continuing with, damaged or when needing maintenance in protective door, needs
It being taken out out of sliding slot simultaneously at the top and bottom of protective door, process of moving not only needs bearer to have good muscle power, and
And the case where being also easy to generation because bearer does not hold steadily, leading to protective door and fuselage damaged in collision, it is unfavorable for the quick of protective door
Dismounting maintenance, numerically-controlled machine tool when in use, the sliding slot of protective door bottom because position is relatively low, usually have dust, cutting clast into
The case where entering, protective door caused to be difficult to effectively slide.
Invention content
The present invention provides a kind of numerically-controlled machine tool protective door, can effectively solve to propose existing market in above-mentioned background technology
Protective door structure it is simple, after long-time use, frictional force increases in sliding process, causes protective door sliding slow, and slide

It is interior so that when the both sides for being installed to door body 1 that protection mechanism 16 can be stablized, protective door and fuselage contact, inside sucker 1604
After air discharge, under the action of atmospheric pressure so that the side wall of protective door is tightly attached on fuselage, is reduced door body 1 and is used process
In shaking, while sucker 1604 by installation screw 1605 be mounted on bolt 1603 on, be convenient for quick dismounting and change, solve
Existing rubber sheet gasket replaces the cumbersome problem of flow, and the dustproof sheet 2203 that 2201 outside of door body 1 lower part drying box is installed can have
Effect reduces dust and cuts the case where clast enters in the sliding slot of fuselage bottom, protective door is avoided to be difficult to effectively slide,
The drier in drying box 2201 can effectively absorb the steam of protective door bottom by gauze 2202 simultaneously, avoid 1 bottom of door body
The case where corrosion damages is equipped with movable pulley 14 when protective door moves inside the mounting groove 10 that 1 top of door body opens up,
Movable pulley 14 and the contact of fuselage roof sliding slot are rolled, and convert the sliding friction of existing protective door to rolling friction, from
And achieve the purpose that reduce protective door moving resistance, while the side surface of movable pulley 14 and the fitting of the side surface of regulating wheel 13, it adjusts
The side surface of section wheel 13 and the side surface fitting of fifth wheel 12, the side surface of fifth wheel 12 and the side surface fitting of hollow shaft 7, make
Obtaining movable pulley 14 can effectively drive hollow shaft 7 to be rotated while rotation, the adjustment gear of 7 outer middle side part of hollow shaft installation
9 rotate together with hollow shaft 7, and when movable pulley 14 drives hollow shaft 7 to rotate clockwise, the gear teeth of adjustment gear 9, which squeeze, to be adjusted
Save the side of snap-gauge 603 so that adjustment spring 604 is compressed, and mounting disc 601 and screw rod 5 can not be made to be rotated, movable pulley is worked as
When 14 drive hollow shafts 7 rotate counterclockwise, the gear teeth of adjustment gear 9 block the side for adjusting snap-gauge 603 so that adjustment spring
604 elongations, adjustment gear 9 can effectively drive mounting disc 601 and screw rod 5 to be rotated at this time, the extruding inside grease-box 2
Plate 3 is mounted on by adjusting screw hole 4 on screw rod 5, when screw rod 5 is rotated, in the cooperation of adjusting screw hole 4 internal thread and screw rod 5
Under, stripper plate 3 is slowly moving and squeezes lubricating oil and is flowed into hollow shaft 7, and the company of dropping onto is discharged finally by fluid hole 8
12 surface of cock wheel passes through the contact of fifth wheel 12 and 13 the two side surface of regulating wheel, both regulating wheel 13 and movable pulley 14 side table
The contact in face, finally so that lubricating oil wraps movable pulley 14 so that the frictional force smaller that protective door is subject to when moving is convenient for
The promotion of protective door, while the noise generated when movable pulley 14 slides is reduced, convenient for preferably building the workshop condition of high-quality,
The one direction rotation of screw rod 5 can be effectively ensured in the setting of ratchet mechanism 6, avoid the occurrence of the case where stripper plate 3 moves back and forth, ensure
What lubricating oil can be stablized is squeezed into inside hollow shaft 7, when observing more water stain 17 surface of glass attachment and cutting clast,
Push and pull connecting plate 19 so that carrier wheel 20 carries out rolling back and forth, 20 lower section of carrier wheel along the gear teeth on rack frame 18
Coaxial mounted cleaning brush 21 carries out moving in rotation with the rolling of carrier wheel 20 so that cleaning brush 21 effectively see by cleaning
17 inner surface of glass is examined, cleaning is attached to the aqueous and clast on 17 surface of observation glass, is convenient for the better observed number of observer
The working condition for controlling lathe, removes the spacer pin in limit hole 30, rotating horizontal pole 28 so that vertical shaft 27 drives 26 turns of power gear
It moves, power gear 26 and support rack 24 engage and support rack 24 driven to move down so that support feet 25 from support chamber
It is stretched out in room 23, spacer pin is recycled to fix fixed link 29 and cross bar 28 so that support rack 24 and support feet 25 ensure surely
Surely it plays a supporting role, then to support feet 25 for axis swing protective door so that movable pulley 14 is out of, fuselage roof sliding slot
It takes out, the support feet 25 of 1 bottom of door body is taken out to the dismounting that protective door can be realized out of fuselage bottom sliding slot at this time, solve
Existing protective door needs to take out out of sliding slot simultaneously at the top and bottom of protective door in disassembly process, inconvenient for operation
The problem of, facilitate the fast quick-detach maintenance of protective door.
Finally it should be noted that：The foregoing is merely the preferred embodiments of the present invention, are not intended to restrict the invention, to the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, for those skilled in the art, still can be with
Technical scheme described in the above embodiments is modified or equivalent replacement of some of the technical features.It is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the present invention
