Abstract

A device for polishing metal and plastic parts is solving the problem of standard cleaning or rough polishing - i.e. by using only rotating vessels - of metal and plastic parts in a simple but more effective manner with the combination of rotation and lengthwise swinging, simple and compact structure and easy setup of the device. A swinging holder (3) is inserted within a supporting frame (1) in such a manner that it is swivelly movable in the longitudinal direction at the same time, which is enabled by two points of rotation (20). At each vertical lateral part of the swinging holder (3) there is installed one forked carrier (5) - fixedly assembled with a lengthwise carrier (4) - which is movably connected with the former in the point of rotation (22), and can be opened and closed by rotating threaded bars (21). A drive assembly (14) is intended for the rotation of the polishing vessel (27) by driving, via intermediate elements, a pair of wheels (9) and the latter in turn a pair of wheels (10) which are rotating at the same speed and in the same direction. A driven assembly (15) in which the rotational movement of an eccentric (19) is converted into the linear movement required to swivel the swinging holder (3) with carriers (4) by means of an intermediate element (24) and a cam lobe (23), is intended for swinging the vessel (27).

Description

NAPRAVA ZA ČIŠČENJE IN POLIRANJE DROBNIH KOVINSKIH,DEVICE FOR CLEANING AND POLISHING OF SMALL METALS,

PLASTIČNIH IN LESENIH DELOVPLASTIC AND WOODEN PARTS

Predmet izuma je naprava za čiščenje in poliranje drobnih kovinskih in plastičnih delov ter čiščenje, poliranje in po potrebi tudi za lakiranje lesenih delov z istočasnim rotiranjem in nihanjem osemoglate polirne posode, v katero so vstavljeni (pol)izdelki, polirna telesa prizme, polirna pasta, kremenčev pesek in voda ali polirna emulzija. V primeru lesenih delov pa oblanci z dodatki za impregnacijo in lakiranje.The subject of the invention is a device for cleaning and polishing of small metal and plastic parts, as well as cleaning, polishing and, if necessary, also for varnishing of wooden parts with simultaneous rotation and oscillation of a polished container in which (semi) products, polishing bodies of prisms, polishing paste are inserted, silica sand and water or polishing emulsion. In the case of wooden parts, impregnation and lacquer trims.

S prijavo št.: 200300103 z dne 23.04.2003 in na osnovi le-te izdanem patentu št.:SI 21452 A, je prijavljena NAPRAVA ZA UMIVANJE LESENIH SODOV. Naprava je skozi vsa leta, bila izpopolnjevana (dodan je frekvenčni pretvornik, podpora pogona, lovilno korito za izlivne tekočine, varnostna mreža, itd). Končno je izdelana osemkotna posoda 27, z namenom poliranja in čiščenja obrobkov (portov) kovinskih (in plastičnih) delov ter lesenih (pol)izdelkov. Vrtijo jo torna kolesa samega ležišča, kolesni dvojici 9 in 10. Kolesa so standardna, izdelana iz trde gume, po katerih tečejo štirje obroči izdelani iz cevi, privarjeni na samo posodo. Posoda 27 je izdelana iz kakovostne 3 mm jeklene pločevine, dno posode je na eni strani zaprto iz cele pločevine, na drugi strani je osemkotna odprtina s tesnilom in v njo vgrajen pokrov.By application No .: 200300103 of 23.04.2003 and patent no .: SI 21452 A, issued on the basis thereof, a WASHING VESSEL WASHER is hereby notified. The device has been upgraded over the years (frequency converter, drive support, drain pan, safety net, etc. added). Finally, an octagonal container 27 is made for the purpose of polishing and cleaning the edges (ports) of metal (and plastic) parts and wooden (semi) products. It is rotated by the friction wheels of the bunk itself, wheel pairs 9 and 10. The wheels are standard made of hard rubber, through which run four rings made of tubes welded to the container itself. The container 27 is made of high quality 3 mm steel sheet, the bottom of the container is closed on one side from the whole sheet metal, on the other side there is an octagonal opening with a gasket and a lid in it.

K eni napravi sodi ena posoda ali več. Odvisno od proizvodnega takta; hitreje teče postopek s tremi posodami: Ena na stroju, druga čaka polna na premik na napravo, tretja pa se prazni in kontrolira. Posoda se praviloma namesti in dvigne z dvigalom (nameščenim na konzoli ali viseči cevni progi nad napravo).One device includes one or more containers. Depending on the production clock; the process with three vessels is faster: one is on the machine, the other is waiting full to move to the device, and the third is emptied and controlled. As a rule, the container is mounted and lifted by an elevator (mounted on a console or suspended hose above the device).

Tehnični problem, ki ga rešuje izum, je takšna konstrukcija naprave, ki bo omogočala čiščenje (robkanje bradic) ter poliranje drobnih kovinskih in plastičnih delov po klasičnem postopku na popolnoma mehanski način, z hkratno rotacijo, oziroma obračanjem polirne posode okrog vzdolžne osi in izmeničnim nihanjem polirne posode po dolžini tako, da se bosta konca posode v navpični smeri izmenično gibala gor in dol. Hkrati bo celotna konstrukcija naprave kompaktna in enostavna, z možnostjo njene proste postavitve, kot tudi fiksne pritrditve na, oziroma v poljubno podlago, prednostno znotraj prostorov obdelovalnega obrata.A technical problem solved by the invention is the construction of a device that will allow cleaning (wrinkling of the beards) and polishing of small metal and plastic parts according to the classical procedure in a completely mechanical manner, with simultaneous rotation or rotation of the polishing vessel around the longitudinal axis and alternating oscillation polishing vessels in length so that the ends of the vessels are vertically up and down alternately. At the same time, the overall construction of the device will be compact and simple, with the possibility of its free placement, as well as a fixed attachment to, or to any substrate, preferably within the premises of the processing plant.

Znana je rešitev, ki v celoti temelji na izključno rotirajoči posodi, brez hkratnega nihanja posode. Pri tem se uporablja okrogla posoda, pogosto lesena ali kovinska z vratci za odvzemanje in ponovno vstavljanje delov v posodo, na bočni strani posode, kar se dela ročno, je zamudno in čas delovanja je izjemno dolg.There is a well-known solution based entirely on an exclusively rotating container without simultaneously oscillating the container. This uses a round container, often wooden or metal with a door to remove and reinsert the parts in the container, which is done manually on the side of the container, which is time consuming and extremely long.

Druga znana rešitev je strojna naprava, ki jo v osnovi sestavlja nekaj metrov veliko kolo z zobatim vencem ob eni notranji strani kolesa, sestavljenega iz dveh obročev, med katerimi so vstavljene štiri polirne posode. Vsaka od teh posod ima svoj pogonski zobnik, vzobljen v zobati venec velikega kolesa. Tako se veliko kolo vrti v eni smeri, vse štiri posode pa vsaka zase v nasprotni smeri. V posodah, ki so okrogle, so kovinski deli s pripadajočo polirno vsebino (polirne prizme, telesa - NORTON, ATLANTIC, pesek, pasta, emulzija, itd.).Another well-known solution is a machine device consisting essentially of a several-meter-large wheel with a toothed rim along one inner side of the wheel, consisting of two rings, between which four polishing vessels are inserted. Each of these vessels has its own drive sprocket, pinned to the large wheel gear. Thus, the large wheel rotates in one direction, and all four vessels are each in the opposite direction. Containers that are circular include metal parts with the associated polishing content (polishing prisms, bodies - NORTON, ATLANTIC, sand, paste, emulsion, etc.).

Tretja znan rešitev je polirna posoda z vibracijskim pogonom. Posoda je napolnjena s polirno vsebino, vstavljeni so kovinski ali plastični deli in posoda, ki je pritrjena na vzmetnih podstavkih, se preko ustreznega pogona stresa oziroma vibrira, deli gnani z vibracijo, pa se gibljejo skozi polirni medij in jih na tak način očistijo, polirajo ali finiširajo.A third known solution is a vibration-driven polisher. The container is filled with polishing contents, metal or plastic parts are inserted, and the container, which is attached to the spring pads, is vibrated through the appropriate actuator of stress or vibration, the parts are driven by vibration, they move through the polishing medium and are thus cleaned, polished or finish.

Skupna značilnost vseh znanih rešitev je v zamudnem načinu polnjenja in praznjenja polirnih posod. Vsako je treba, več ali manj, ročno izprazniti in nato ponovno napolniti. V tem času naprava miruje. Učinki teh naprav so zaradi tega manjši kot bi sicer lahko bili. Problem, ki je ostal tudi nerešen, je predvsem naporno in nečisto fizično delo pri praznjenju in polnjenju polirnih posod ter transportiranju obdelovancev od posode in k posodi.A common feature of all known solutions is the time consuming mode of filling and emptying polishing vessels. Each, more or less, must be manually drained and then refilled. During this time, the device is idle. The effects of these devices are therefore less than they might otherwise be. The problem, which has remained unsolved, is, above all, the arduous and unclean physical work of emptying and filling polishing vessels and transporting workpieces from the container to the container.

Po izumu je problem rešen z napravo za čiščenje in poliranje delov, ki se v bistvu sestoji iz nihalnega nosilca in iz škarjastega nosilca , pritrjenih na skupni podstavek z dvema kolesnima dvojicama, poganja pa ju pogonski agregat in to preko pogonskega in gnanega sklopa. Obenem pa je prednost naprave v tem, da polirna posoda ni fiksirana na napravo, ampak jo z lahkoto dvignemo z naprave in takoj namestimo novo, napolnjeno posodo na njeno mesto.According to the invention, the problem is solved by a device for cleaning and polishing parts, which essentially consists of a pendulum carrier and a scissor carrier, attached to a common pedestal with two wheelsets, driven by a drive unit through a drive and driven assembly. At the same time, the advantage of the device is that the polishing container is not fixed to the device, but can easily be lifted from the device and immediately installed a new, filled container in its place.

Izum bo natančneje opisan na prednostnem izvedbenem primeru in slikah, ki prikazujejo:The invention will be more specifically described in the preferred embodiment and in the drawings showing:

Osnovno nosilno konstrukcijo naprave za čiščenje in poliranje kovinskih, plastičnih in lesenih delov, predstavlja podstavek 1 prednostno pravokotne oblike, katerega nivelacijo omogočajo nivelacijski vijaki 2, ki so nanj nameščeni s spodnje strani, prednostno v njegovih vogalih. V nekem drugem izvedbenem primeru, je lahko podstavek 1 tudi drugačnih oblik, izveden brez regulacijskih vijakov in preko sider ali s poljubno spojno zvezo fiksno pritrjen na , oziroma v podlago. Znotraj okvirja, ki ga tvori podstavek 1, je gibljivo nameščen nihalni nosilec 3, ki je izveden tako, da je s horizontalnim okvirjem podstavka 1, krožno - gibljivo spojen preko vrtišč 20, hkrati pa je preko vrtišč 22, prav tako krožno gibljivo, spojen s škarjastima nosilcema 5, ki sta na obeh koncih nihalnega nosilca 3, vertikalno nameščena. Vrtišči 20 si ležita nasproti in sta praviloma izvedeni in pozicionirani na polovici daljših stranic podstavka 1 oziroma, nihalnega nosilca 3, medsebojno pa ju povezuje fiksni drog 30. Prav tako si ležita nasproti vrtišči 22, ki sta pozicionirani na polovici krajših stranic podstavka 1 in ležita nekoliko nad njim. Skupna središčna os vrtišč 20 leži praviloma pod pravim kotom na skupno središčno os vrtišč 22. Nihalni nosilec 3 je izveden kot horizontalno ležeči okvir, katerega daljši stranici sta ravni in sta si vzporedni, dočim sta krajši stranici vbočeno izvedeni. Na ta okvir, sta na strani krajših stranic, pravokotno nameščena še dva podolgovata profila, ki sta nanj v vogalih fiksno pritrjena, njuna nasprotna konca pa sta spojena v vrtišču 22. Glede na opisano, ima v čelnem pogledu nihalne naprave nihalni nosilec 3 obliko korita z vbočenim dnom, kar je prikazano na sl. 2/6. Vsi profili, oziroma vsi kraki nihalnega nosilca 3, so med sabo fiksno privarjeni ali kako drugače fiksno pritrjeni tako, da tvorijo enovito togo konstrukcijo, ki je, preko prej opisanih parov vrtišč 20 in 22, znotraj naprave nihajoče gibljiva tako v vzdolžni, kot tudi v prečni smeri. Pri tem navojni drogovi 21 služijo za razširitev ali zoženje kota α škarjastega nosilca 5 s fiksno privarjenima vzdolžnima nosilcema 4, ki ga po nastavitvi kota α in izenačitvi ugreza obeh krajnih robov nihalnega nosilca 3 okrog osi nihanja, fiksiramo z nastavljivim vijakom 29 znotraj izreza 28 v kulisi 23. Kulisa 23 je preko veznega elementa 24 gibljivo spojena z ekscentrom 19. Vloga veznega elementa 24 je predvsem v tem, da krožno gibanje ekscentra 19, pretvori v linijsko, oziroma nihajoče gibanje vzdolžnega nosilca 4 s škarjastima nosilcema 5 ter preko vrtišča 22 prenese na nihalni nosilec 3. Vezni element 24 je lahko, na primer, izveden kot ojnica ali je temu ustrezno lahko drugačne izvedbe. V nekem drugem izvedbenem primeru, je lahko nihalni nosilec 3 izveden in oblikovan tudi kako drugače, pri čemer pa mora zadostiti pogoju vrtišč 20 ter 22 in zunaj oblike polirne posode, prav tako pa je mogoča izvedba, ki bo omogočala nastavitev dolžine njegovega nihanja.The basic load-bearing structure of the device for cleaning and polishing metal, plastic and wooden parts is a base 1, preferably rectangular in shape, whose leveling is enabled by the leveling screws 2, which are mounted on it from the underside, preferably in its corners. In another embodiment, the base 1 may also be of different shapes, made without adjusting screws and fixed anchored to or on the base via anchors or with any connection joint. Within the frame formed by the base 1 there is a pivotally mounted pivot carrier 3, which is arranged in such a way that it is connected to the horizontal frame of the base 1, circularly - movably through the pivots 20, and simultaneously connected through the pivots 22, also circularly movable. with the shear brackets 5 vertically positioned at both ends of the pivot bracket 3. The edges 20 are opposite and are generally made and positioned halfway along the longer sides of the base 1 or, respectively, the pivot carrier 3, and are interconnected by a fixed pole 30. Also opposite the pivots 22 are positioned halfway down the shorter sides of the base 1 and lie a few over him. The common center axis of the pivots 20 is generally at right angles to the common center axis of the pivots 22. The pivot carrier 3 is designed as a horizontal frame, the longer sides of which are straight and parallel and the shorter sides convex. On this frame, on the side of the shorter sides, are perpendicularly mounted two more elongated profiles, which are fixed in the corners and their opposite ends are connected in the pivot 22. According to the described, the oscillating device 3 in the front view of the oscillating carrier has the shape of a trough with a concave bottom, as shown in FIG. 2/6. All profiles, or all arms of the pendulum beam 3, are welded or otherwise fixed to each other to form a uniform rigid structure which, via the previously described pairs of pivots 20 and 22, is oscillating within the device both in the longitudinal and in the transverse direction. The threaded rods 21 are used for widening or narrowing the angle α of the shear bracket 5 with the fixed welded longitudinal brackets 4, which, after adjusting the angle α and equalizing the draft of the two edges of the oscillating bracket 3 around the axis of oscillation, are fixed by an adjustable screw 29 inside the recess 28 The backdrop 23. The backdrop 23 is movably connected to the eccentric via the connecting element 24. to the swingarm 3. The connecting element 24 may, for example, be made as a connecting rod or may be of a different design accordingly. In another embodiment, the oscillating support 3 may also be designed and shaped in a different manner, while meeting the conditions of the pivots 20 and 22 and outside the shape of the polishing vessel, as well as a design that will allow the length of its oscillation to be adjusted.

Znotraj cele dolžine nihalnega nosilca 3 in vzporedno z njegovima daljšima stranicama, sta vzporedno nameščena podolgovata nosilca 4, ki sta en od drugega nekoliko odmaknjena, oziroma sta enako oddaljena od vzdolžne središčne osi in na koncih fiksno privarjena na škarjasta nosilca 5. Preko vrtišča 22, sta konca podolgovatih nosilcev 4 preko škarjastihWithin the entire length of the pendulum beam 3 and parallel to its longer sides, elongated beams 4, which are slightly spaced from one another or equally spaced from the longitudinal center axis and fixed at the ends to the shear brackets 5, are mounted in parallel. the ends of the elongated brackets 4 are through the scissors

nosilcev 5, gibljivo vezana na nihalni nosilec 3. Na vsak nosilec 4 je krožno, gibljivo ter preko para ležajev 11 pritrjena kolesna dvojica 9 oziroma 10 tako, da sta nanju nameščeni v smeri njune vzdolžne osi, locirana pa sta v območju prečne središčne osi nosilcev 4 in sta si vzporedni. Vsaka kolesna dvojica 9 oziroma 10, je z obeh strani obdana z najmanj po enim opornim kolesom 7, ki je rotacijsko gibljivo vstavljen v pripadajočo konzolo 8, pritrjeno na nosilec 4. Oporna kolesa 7 s konzolami, so od pripadajoče kolesne dvojice 9 in 10 enako oddaljena.of the brackets 5, movably connected to the pivot bracket 3. Wheel brackets 9 and 10 are mounted circularly, movably and through a pair of bearings 11 to each bracket 4, so that they are mounted in the direction of their longitudinal axis and are located in the region of the transverse center axis of the brackets 4 and are parallel. Each wheel pair 9 and 10, respectively, is surrounded on each side by at least one support wheel 7, which is rotatably inserted into the corresponding bracket 8, attached to the bracket 4. The support wheels 7 with brackets are identical to the corresponding wheel pair 9 and 10 away.

Na notranji strani vsakega od obeh vertikalnih delov nihalnega nosilca 3 in z njima vzporedno, je nameščen po en škarjasti nosilec 5, fiksno privarjen na nosilec 4. Sestoji iz dveh pokončnih krakov, ki sta pri vrhu spojena preko vrtišča 22 z nihalnim nosilcem 3, dočim sta s spodnjim koncem vsak zase spojena z navojnimi drogovi 21 tako, da je en krak spojen z delom, ki ima levi, drugi krak pa z delom, ki ima desni navoj. Razmak med spodnjima koncema krakov škarjastega nosilca 5 z vzdolžnima nosilcema 4 ter s tem velikost njunega medsebojnega notranjega kota a, se nastavi z vrtenjem navojnih drogov 21 v eno ali drugo smer.On the inside of each of the two vertical portions of the pendulum bracket 3 and in parallel with them, one scissor bracket 5 is fixed, welded to the bracket 4. It consists of two upright arms connected at the top via a pivot 22 with the pendulum bracket 3 to the daughter. they are each connected to the lower end by a threaded bar 21 so that one arm is joined to a portion having a left thread and the other arm to a portion having a right thread. The distance between the lower ends of the legs of the shear bracket 5 with the longitudinal brackets 4, and thus the size of their inner inner angle a, is adjusted by rotating the threaded rods 21 in one direction or another.

Napravo poganja pogonski agregat (el. motor z reduktorjem) 6, privijačen na nosilno ploščo in nosilca 25, ki sta fiksno privarjena na podolgovati nosilec 4 s kolesno dvojico 9. Pogonski sklop14 poganja gnani sklop 15 z ekscentrom 19, ki je, kot je predhodno že navedeno, gibljivo spojen z veznim elementom 24 in dalje preko kulise 23 ter vrtišča 22 gibljivo spojen z nihalnim nosilcem 3. Prenos rotacijskega gibanja med pogonskim sklopom 14 in med gnanim sklopom 15, je lahko, kot prikazano v prednostnem izvedbenem primeru, izveden s pomočjo stožčastih zobnikov in vmesne sklopke, pri čemer vzdolžni osi sklopov 14 in 15 oklepata notranji medsebojni pravi kot. V nekem drugem izvedbenem primeru, sta lahko pogonski sklop 14 in gnani sklop 15 izvedena tudi kako drugače.The device is driven by a drive unit (electric motor with reducer) 6, screwed onto the support plate and brackets 25, which are fixed to the elongated bracket 4 with a wheel pair 9. The drive assembly 14 is driven by a driven assembly 15 with an eccentric 19, which is as before already mentioned, movably coupled to the coupling element 24 and further through the scaffold 23 and pivot 22 pivotally coupled to the pivot carrier 3. The transfer of rotational motion between the drive assembly 14 and between the drive assembly 15 may be accomplished by means of, as shown in the preferred embodiment, bevel gears and intermediate couplings, wherein the longitudinal axes of the couplings 14 and 15 enclose the inner right angles. In another embodiment, the drive assembly 14 and drive assembly 15 may also be implemented differently.

Pogonski sklop 14 hkrati poganja tudi kolesni dvojici 9 in 10 na nosilcih 4, ki se praviloma vrtita z enako hitrostjo in v isto smer. V ta namen se znotraj pogonskega sklopa 14 nahaja enojno verižno kolo 31, ki je z neskončno verigo16, povezano z dvojnim verižnim kolesom12 na kolesni dvojici 9. Dvojno verižno kolo 12 je nadalje in preko neskončne verige 17 povezano še z enojnim verižnim kolesom 13 na kolesni dvojici 10. Daje neskončna veriga 17 ustrezno napeta, zagotovi napenjalec 18, fiksno spojen na vezni profil 26, kar lahko enako velja tudi za neskončno verigo 16.The drive assembly 14 also drives the wheel pairs 9 and 10 on the supports 4, which generally rotate at the same speed and in the same direction. For this purpose, a single chain wheel 31 is connected to the drive assembly 14, which is connected to the double chain wheel 12 by a wheel pair 9 with an endless chain16. The double chain wheel 12 is further connected via a continuous chain 17 to a single chain wheel 13 on the wheel doubles 10. Given that the endless chain 17 is properly tensioned, it provides a tensioner 18, fixedly connected to the connecting profile 26, which can equally be true of the endless chain 16.

Dimenzije naprave za čiščenje in poliranje drobnih delov, so odvisne od velikosti polirnih posod, za katere so namenjene. Znotraj volumenskega intervala polirnih posod, je to mogoče doseči s prednastavitvijo naprave. V ta namen je naprava izvedena tako, da je mogoče razmak med nosilcema 4, na katerem so nameščeni pari opornih koles 7 in kolesni dvojici 9 in 10, nastaviti, to je zmanjšati ali povečati. To je izvedljivo z vrtenjem navojnih drogov 21 v ustrezno smer, preko katerih na ta način širimo ali ožimo kot α škarjastega nosilca 5. Pred začetkom uporabe naprave, je potrebno izvesti še uravnoteženje nihajev polirne posode v obe smeri, oziroma gibanja nihalnega nosilca 3. To storimo z nastavitvijo gnanega sklopa 15, torej z nastavitvijo ekscentra 19 ter s položajem nastavljivega vijaka 29, znotraj izreza 28 v kulisi 23 ob istočasnem prilagajanju podpore pogona 37 (dviganju ali spuščanju celotnega pogona). Sam prenos pogona rotacije dosežemo s pravilnim dimenzioniranjem medsebojnega prenosa med enojnim verižnim kolesom 31 in dvojnim verižnim kolesom 12 ter nadalje med njim in enojnim verižnim kolesom 13, ki jih medsebojno povezujeta neskončni verigi 16 in 17. Pripadajoča električno-elektronska oprema s frekvenčnim pretvornikom pa omogoča enostavno in hitro prilagajanje režima delovanja naprave, glede na velikost in težo polirne posode s spreminjanjem števila obratov le-te ali smeri vrtenja posode naprej ali nazaj.The dimensions of the device for cleaning and polishing small parts depend on the size of the polishing vessels for which they are intended. Within the volume interval of polishing vessels, this can be achieved by presetting the device. For this purpose, the device is designed in such a way that the distance between the supports 4, on which the pairs of support wheels 7 and the wheelsets 9 and 10 can be adjusted, can be reduced or increased. This is feasible by rotating the threaded rods 21 in the appropriate direction, through which in this way we extend or narrow as α the scissor carrier 5. Before starting to use the device, it is necessary to balance the oscillations of the polisher in both directions, or the movements of the oscillating carrier 3. This we do this by adjusting the driven assembly 15, ie by adjusting the eccentric 19 and by positioning the adjustable screw 29, inside the recess 28 in the recess 23 while adjusting the support of the actuator 37 (raising or lowering the entire actuator). The rotary drive transmission itself is achieved by properly dimensioning the transmission between the single chain wheel 31 and the dual chain wheel 12 and further between it and the single chain wheel 13, which are interconnected by endless chains 16 and 17. The associated electrical and electronic equipment is enabled by the frequency converter easy and quick adjustment of the operating mode of the device, depending on the size and weight of the polishing tank by varying the number of revolutions of the polishing tank or the direction of rotation of the tank forward or backward.

Celotna naprava in nje delovanje, je varovano z zaščitno (varovalno) mrežo 32 ter drsnikoma na spodnjem kocu mreže 33 s končnima stikaloma 34.The whole device and its operation is protected by a protective (safety) net 32 and sliders on the lower cage of the net 33 with end switches 34.

Osemoglata polirna posoda 27 je izdelana iz plašča posode 39, fiksno zvarjenega z osemoglatim dnom posode 40, ter vstavljenim pokrovom 41 na drugi strani posode, ki je v nekem drugem primeru lahko izveden tudi drugače, ter zateznimi vijaki 42, fiksno pritrjenimi na obrobo odprtine posode. Posoda je obdana z dvema večjima nosilnima obročema iz cevi 43 ter dvema manjšima naslonskima obročema 44. Vsi obroči so fiksno spojeni na oglišča posode.The charred polishing vessel 27 is made of a housing container 39 fixedly welded to a charred bottom of the tank 40, and an inserted lid 41 on the other side of the container, which may otherwise be made otherwise, and clamping screws 42 fixed to the periphery of the container opening. . The container is surrounded by two larger support rings made of pipe 43 and two smaller support rings 44. All rings are fixed to the corners of the container.

Ko v napravo, oziroma na kolesni dvojici 9 in 10 položimo polirno posodo 27 z nosilnimi obroči na torna pogonska in naslonska kolesa, le-to vklopimo preko elektroomarice 35, po naslednjem zaporedju:When a polishing vessel 27 with load-bearing rings on the friction drive and back wheels is placed in the device, or on the wheel pairs 9 and 10, it is switched on via the battery 35, in the following order:

Predhodno preverimo dovodni priklop na vtikač, preverimo izklopljenost stikala za trenutni izklop S3, vključimo glavno stikalo S1, zapremo zaščitno mrežo 32 ter postavimo rele za nastavitev hitrosti R1 v ničelni položaj (popolni zasuk v levo). Sledi vklop omrežja omarice s pritiskom na vklopno tipko S2 (zasveti se kontrolna lučka H1). Za izbor želenega vrtenja polirne posode 27 naprej, pritisnemo vklopno tipko S6 ali za nazaj vklopno tipko S5. S postopnim vrtenjem relejnega koleščka R1 v desno, zaženemo pogonski agregat 6, ki hkrati požene pogonski sklop 14 in gnani sklop 15. Enojno verižno kolo 31, znotraj pogonskega sklopa 14, preko neskončne verige 16 in dvojnega verižnega kolesa 12, poganja kolesno dvojico 9 ter dalje preko neskončne verige 17 in enojnega verižnega kolesa 13, tudi kolesno dvojico 10. Kolesni dvojici 9 in 10 se prednostno vrtita z enako hitrostjo in v isto smer, kar omogoča pravilno rotacijo polirne posode 27. Hkrati pogonski sklop 14 poganja tudi gnani sklop 15, ki rotacijsko gibanje ekscentra 19, preko veznega elementa 24, pretvori v linijsko, oziroma premočrtno nihalno gibanje nihalnega nosilca 3. Na ta način polirna posoda 27, niha v smeri svoje vzdolžne osi oziroma po dolžini. Naprava za čiščenje in poliranje drobnih delov deluje torej tako, da v njej polirna posoda 27 hkrati izvaja rotacijsko in nihalno gibanje. Z njo dosežemo razbremenitev ročnega dela pri polnjenju in praznjenju polirnih posod drugih omenjenih naprav, odpravimo transport vsebine v drugih posodah, pospešimo sam • · θ ··· ·· ------tehnološki proces z zamenjavo polirnih posod na sami napravi, ob tem pa tehnologija čiščenja in poliranja v polirni posodi 27, ki opravlja rotacijske in nihalne gibe, poveča učinkovitost čiščenja in poliranja za nekajkrat.We check the supply connection to the plug beforehand, check that the S3 switch is switched off, switch on the main switch S1, close the safety net 32 and set the speed setting relay R1 to zero (full left rotation). This is followed by switching on the cabinet network by pressing the power button S2 (control indicator H1 lights up). To select the desired rotation of polishing tank 27 forward, press the S6 key or the S5 back button. By gradually turning the relay wheel R1 to the right, we start the drive unit 6, which simultaneously drives the drive assembly 14 and the drive assembly 15. A single chain wheel 31, inside the drive assembly 14, through an endless chain 16 and a double chain wheel 12, drives the wheel pair 9 and further through the endless chain 17 and the single chain wheel 13, also the wheel pair 10. The wheel pairs 9 and 10 are preferably rotated at the same speed and in the same direction, allowing the rotary pole to be rotated 27. At the same time, the drive assembly 14 is also driven by the driven assembly 15, which transforms the rotational movement of the eccentric 19 through the connecting element 24 into a linear or rectilinear oscillatory motion of the oscillating carrier 3. In this way, the polishing vessel 27 oscillates in the direction of its longitudinal axis or in length. The device for cleaning and polishing small parts therefore operates in such a way that the polishing vessel 27 performs rotational and oscillatory movement at the same time. It achieves the relief of manual labor in filling and emptying the polishing vessels of other mentioned devices, eliminating the transport of contents in other containers, accelerating the technological process itself by replacing the polishing vessels on the device itself, at in this way, the cleaning and polishing technology in the polishing vessel 27, which performs rotary and oscillatory motions, increases the efficiency of cleaning and polishing by several times.

Znotraj delovnega prostora, kjer naprava deluje, je predvideno dvigovanje in premeščanje polirnih posod s priročnim stropnim ali stenskim konzolnim dvigalom. Za varno delovanje je predvidena prekrivna, varnostna mreža 32, katere zaprti položaj je pogoj za njen zagon. Na vogalnem, spodnjem delu okvira pokrivne varnostne mreže, sta z obeh strani pritrjena ploščata drsnika 33, ki se ob zaprtju zaščitne mreže naslonita na kontaktni valjček končnega stikala 34 (S7 in S8) in s tem omogočita zagon naprave.Inside the work area where the machine is operating, it is planned to lift and move the polishing vessels with a convenient ceiling or wall cantilever lift. For safe operation, an overlapping safety net 32 is provided, the closed position of which is a prerequisite for starting it. On the corner, lower part of the cover of the safety net cover, flat sliders 33 are attached on both sides, which, when the protective net is closed, rest on the contact roller of the limit switch 34 (S7 and S8), thus allowing the device to start.

Na ogrodje pokrivne varnostne mreže 32, je na zunanji strani pritrjena elektroomarica 35, katere vsebina je ponazorjena s priloženo vezalno shemo. Omogoča vse potrebne funkcije varnega pogona naprave: Zagon naprej ali nazaj, izklop delovanja naprave, varnostni, trenutni izklop pogona, prestavitev smeri vrtenja posode, pospešitev ali upočasnitev hitrosti vrtenja in stikalo za vklop in izklop omrežja ter šuko vtičnico 38.To the frame of the safety net 32, an electrical box 35 is mounted on the outside, the contents of which are illustrated by the attached wiring diagram. It provides all the necessary safe drive functions for the machine: Starting forwards or backwards, shutting down the unit, safety, instantaneous shutdown of the drive, changing the direction of rotation of the container, accelerating or slowing down the rotation speed, and the switch for switching on and off the network and the shock socket 38.
