Description

i 147196 1 Opfindelsen angår en indstillelig beskyttelsesskærm til værktøjsmaskiner, hvilken beskyttelsesskærm er af den i krav l’s indledning angivne art.The invention relates to an adjustable protective machine tool screen which is of the kind specified in the preamble of claim 1.

5 Under betjening af en spåntagende værktøjsmaskine som en drejebænk kan de varme spåner, der kastes bort fra det bearbejdede arbejdsemne, forårsage alvorlige skader på operatøren. Øjenskader er særligt almindelige i maskinfabrikker. For at undgå nævnte skader er det 10 nødvendigt enten at anvende personlige beskyttelsesmidler som beskyttelsesbriller eller masker eller at forsyne værktøjsmaskinerne med beskyttende indkapsling eller afdækning.5 When operating a chip-making machine tool such as a lathe, the hot chips thrown away from the machined workpiece can cause serious damage to the operator. Eye damage is especially common in machine factories. To avoid said damage, it is necessary either to use personal protective equipment such as goggles or masks or to provide the machine tools with protective enclosure or cover.

Personlige beskyttelsesmidler er ofte' ubehagelige og ridses let, ligesom de let virker hæmmende i arbejdsprocessen. Som. følge heraf fjernes beskyttelsesmidlerne ofte, når det er nødvendigt omhyggeligt at iagttage arbejdsemnet, som er under bearbejdning, medens 20 bearbejdningen foregår. Risikoen for uheld under disse omstændigheder er selvindlysende.Personal protective equipment is often 'uncomfortable' and easily scratched, as well as being easily inhibited in the work process. As. as a result, the protective agents are often removed when it is necessary to carefully observe the workpiece being machined while machining is in progress. The risk of accidents in these circumstances is self-evident.

Eksempelvis er rotationsfræsemaskiner i almindelighed udformet med sideværts bevægelige, lodrette afskærm-25 ninger, der normalt er lavet af stål. Sådanne beskyttelsesskærme er relativt velanvendelige i forbindelse med bearbejdningsprocesser af længere varighed (for eksempel til fremstilling af tandhjul), men er upraktiske og ubekvemme i forbindelse med operationer af 30 kortere varighed. Skærmene forhindrer uforstyrret observation af beaEbejdningsprocessen og medfører, at det er besværligt og langsomt at skifte såvel det arbejdsemne, som bearbejdes som værktøjsmaskinens bearbejdende værktøjer.For example, rotary milling machines are generally formed with laterally movable vertical shields usually made of steel. Such protective screens are relatively useful in connection with longer-lasting machining processes (for example, for the production of gears), but are impractical and inconvenient for shorter-duration operations. The screens prevent undisturbed observation of the machining process and cause it to be difficult and slow to change both the workpiece being machined and the machine tool machining tools.

2 U719-6 1 Por nogle maskiner f. eks. drejebænke og rotationsslibemaskiner kommer de ovenfor beskrevne beskyttelsesskærme slet ikke på tale, og sædvanligvis benyttes på sådanne maskiner beskyttelsesglas eller 5 afskærmningsindretninger, som bæres af arme, og som er fastgjort til værktøjsmaskinens chassis ved hjælp af skruer eller magneter. Sådanne arrangementer beskrives for eksempel i den finske patentbeskrivelse nr. 28 678 og i den tyske patentansøgning nr. 2 451 560. Imidler-10 tid har nævnte arrangementer adskillige ulemper: de understøttende armelementer forstyrrer frit indsyn, konstruktionen er ustabil, skærmene er ikke tilstrækkeligt indstillelige og det område, som dækkes af skærmene er for lille.2 U719-6 1 For some machines, such as lathes and rotary grinders, the above-described protective screens do not apply at all, and usually used on such machines are protective glasses or 5 shielding devices which are carried by arms and which are attached to the machine tool chassis by means of of screws or magnets. Such arrangements are described, for example, in Finnish Patent Specification No. 28,678 and in German Patent Application No. 2,451,560. However, these arrangements have several drawbacks: the supporting arm members interfere with free vision, the construction is unstable, the screens are not sufficiently adjustable and the area covered by the screens is too small.

Fra engelsk patent nr. 1 558 513 kendes en skærm, der er ophængt i en føreskinne, der er monteret over værktøjsmaskinen. Skærmen kan derfor udelukkende forskydes i værktøjsmaskinens længderetning. Det er umuligt at 20 komme tæt på arbejdsemnet uden at fjerne beskyttelsesskærmen. Man kan derfor ikke grundigt inspicere små arbejdsemner, og samtidig være beskyttet af skærmen.English patent No. 1,558,513 discloses a screen suspended in a guide rail mounted above the machine tool. The screen can therefore only be displaced in the longitudinal direction of the machine tool. It is impossible to get 20 close to the workpiece without removing the protective screen. Therefore, it is not possible to thoroughly inspect small workpieces and at the same time be protected by the screen.

Det er opfindelsens formål at afhjælpe ovennævnte u-25 lemper, og dette opnås ved at vognen er forsynet med føringer således, at skjoldet og ram men samlet og begge ophængt i vognen kan bevæges i hovedsagen i vandret stilling på tværs i forhold til føreskinnen og drejebænkens spindel.The object of the invention is to remedy the above-mentioned disadvantages, and this is achieved by providing the carriage with guides so that the shield and frame, but overall and both suspended in the carriage, can be moved substantially in a horizontal position transversely to the front rail and the lathe. spindle.

Herved opnås, at beskyttelsesskjoldet kan føres så tæt på emnet, som værktøjsmaskinen tillader. Det bliver således muligt at inspicere selv små emner under selve bearbejdningen, og samtidig have fuld beskyttelse fra 3 147196 1 skjoldet. Beskyttelsesskærmen ifølge opfindelsen har en stiv struktur og en stabil opbygning, den er let indstillelig og bevægelig i alle retninger, og den kan flyttes langs hele det spåntagende område. Uden be-5 sværlighed kan beskyttelsesskærmen forbindes, så den automatisk bevæger sig f.eks. sammen med værktøjsslæden.This ensures that the protective shield can be brought as close to the workpiece as the machine tool allows. Thus, it becomes possible to inspect even small items during machining itself, and at the same time have full protection from the shield. The protective screen according to the invention has a rigid structure and a stable structure, it is easily adjustable and movable in all directions, and it can be moved along the entire cutting area. Without difficulty, the protective screen can be connected so that it automatically moves e.g. along with the tool carriage.

På grund af sin understøtning er beskyttelsesskærmen 10 let at bevæge mellem forskellige positioner, hvilket medfører, at anvendelsen af beskyttelsesskærmen er mere acceptabel og derfor også bedre finder sted, end ved de besværlige, separate beskyttelsesskærme. Beskyttelsesskærmen kan ganske enkelt trækkes til side, 15 hvorfor udskiftning af arbejdsemne eller af værktøjsmaskinens værktøjer ikke medfører ubehageligheder.Because of its support, the protective screen 10 is easy to move between different positions, which means that the use of the protective screen is more acceptable and therefore also takes place better than with the cumbersome, separate protective screens. The protective screen can simply be pulled aside, which is why replacing the workpiece or the tools of the machine tool does not cause any discomfort.

Opfindelsen vil i det følgende blive nærmere beskrevet under henvisning til tegningen,på hvilken 20 fig. 1 viser en foretrukken udførelsesform for beskyttelsesskærmen ifølge opfindelsen, og fig. 2 viser en vogn og en føreskinne 25 ved skærmen set fra siden...The invention will now be described in more detail with reference to the drawing, in which: FIG. 1 shows a preferred embodiment of the protective screen according to the invention, and FIG. 2 is a side view of a carriage and guide rail 25 at the screen ...

Figurerne 1 og 2 illustrerer.en foretrukken'udformning af skærmen, hvori denne er forbun det med en drejebænk. Denne udformning omfatter føre-30 skinnerne 1, der er parallelle med drejespindelen og fastgjort til de lodrette understøtningsskinner 2, som igen er befæstiget på bæreelementer 3· Bæreelementerne 3 kan fastgøres enten til drejebænkens bagside eller til andet fast fundament. Yderligere om-35 147196 4 1 fatter skærmen vognen 4, som er forbundet med føreskinnerne 1 ved hjælp af rullelejer eller ruller 9, og til den nævnte vogn er beskyttelsesskærmens ramme 5 fastgjort på en sådan måde, at rammen kan 2 bevæges i tværgående retning i forhold til føreskinnerne 1. Det gennemsigtige skjold 6 er fastgjort til rammen 5 ved hjælp af hængsler, som er anbragt ved skjoldets 6 øverste kant. Rammen 5 kan være forsynet med en lampe 7 og en udsugningsslangeforbindelse 10 . 8. Føreskinnernes 1 højde i forhold til det emne, som skal bearbejdes, er let indstillelig, når beskyttelsesskærmen installeres ved justering af understøtningsskinnernes 2 position i forhold til bæreelementerne 3. Føreskinnerne 1 og understøtningsskinnerne 2 15 fremstilles på foretrukken måde af en aluminiumlegering, således at man kan opnå en fornuftig understøtning og struktur, som er både let og stiv.Figures 1 and 2 illustrate a preferred embodiment of the screen in which it is joined by a lathe. This configuration comprises the guide rails 1 parallel to the pivot spindle and attached to the vertical support rails 2, which in turn are attached to the support members 3. The support members 3 can be attached either to the back of the lathe or to another fixed foundation. In addition, the screen comprises the carriage 4, which is connected to the guide rails 1 by means of roller bearings or rollers 9, and to the said carriage the frame of the protective shield 5 is fixed in such a way that the frame 2 can be moved transversely in relative to the guide rails 1. The transparent shield 6 is secured to the frame 5 by hinges located at the upper edge of the shield 6. The frame 5 may be provided with a lamp 7 and a suction hose connection 10. 8. The height of the front rails 1 relative to the workpiece to be machined is easily adjustable when the guard is installed by adjusting the position of the support rails 2 relative to the support members 3. The front rails 1 and the support rails 2 are preferably made of an aluminum alloy, so that one can obtain reasonable support and structure that is both light and rigid.

I overensstemmelse med arbejdsemnets og drejepatro-20 nens diameter indstilles skjoldet 6 i en ideel stilling ved at bevæge rammen 5 i forhold til vognen 4.In accordance with the diameter of the workpiece and turning cartridge 20, the shield 6 is set in an ideal position by moving the frame 5 relative to the carriage 4.

Deres indbyrdes stilling kan fikseres f.eks. ved anvendelse af strammeskruer. Herudover kan skjoldet 6 svinges op og ned i sin hængselophængning. Hele vog-25 nen 4, inklusive skjoldet 6, kan let skydes til siden på føreskinnerne 1, f.eks. når arbejdsemnet skiftes ud eller måles.Their mutual position can be fixed e.g. using tightening screws. In addition, the shield 6 can be swung up and down in its hinge suspension. The entire carriage 4, including the shield 6, can be easily slid to the side of the guide rails 1, e.g. when the workpiece is replaced or measured.

Skærmen kan udformes på adskillige andre måder end 30 ifølge denne foretrukne udførelsesform, f.eks. kan skinnernes struktur og deres indbyrdes positioner modificeres efter, hvad man finder egnet for forskellige typer værktøjsmaskiner.The screen may be formed in several ways other than 30 according to this preferred embodiment, e.g. For example, the structure of the rails and their positions can be modified according to what is suitable for different types of machine tools.
