Description

Uppfinnare: T. I. Carlsson. Inventor: T. I. Carlsson.

Prioritet begard frill den 25 mai 1945 (Finland). Priority was given on 25 May 1945 (Finland).

Foreliggande uppfinning avser ett modifierat utfarande av anordningen enligt paten-let nr nr 120 408. \rid det i sagda patent visade utforingsexemplet är drivaxeln for slipduksbandets drivskiva saint bararmen fOr den spannrullen uppbarande havarmen hada uppburna av samma maskinstativ. Till skillnad darifra'n kannetecknas foreliggande uppfinning i huvudsak darav, att den med spannrullens havarm vridbart forenade bararmen Si uppburen av en sarskild, vid sidan av det drivskivans drivaxel uppbarande maskinstativet belagen del. Sagda del bildar salunda tillsammans med bararmen och spannrullen jamte den denna uppbarande havarmen ett sarskilt aggregat, vilket dá kan anbringas intill en I. ex. redan befintlig maskin eller liknande, 5_ vilken finnes en driven ax-el, a vars fran maskinstativet pa i huvudpatentet angivet satt utskjutande dude anbringas en drivskiva for slipduksbandet. The present invention relates to a modified embodiment of the device according to patent no. 120 408. In the exemplary embodiment shown in said patent, the drive shaft for the drive pulley of the abrasive cloth belt saint bar arm for the tensioning arm supporting the tensioning roller had been supported by the same machine frame. In contrast, the present invention can be characterized mainly in that the bar arm Si rotatably connected to the clamping roller arm is supported by a special part of the machine frame supported on the drive shaft of the drive pulley. Said part thus together with the bar arm and the tensioning roller, together with the sea arm carrying it, forms a special unit, which can then be fitted next to an I. ex. an existing machine or the like, in which there is a driven shaft, on which a drive pulley for the abrasive cloth belt is applied from the machine frame on the set protruding dude specified in the main patent.

Uppfinningen beskrives nedan narmare under hanvisning till ett a bifogade ritning visat utforingsexempel. The invention is described in more detail below with reference to an exemplary embodiment shown in the accompanying drawing.

Fig. 1 visar slipanordningen i sidovy. Fig. 2 och 3 visa detaljer. ritningen betecknar 30 en t. ex. av en elektrisk motor 1 driven axel, vars ena drivskivan 3 uppbarande ande skjuter ur fran ett axellagringen resp. motorn 1 uppbarande maskinstativ 4 pA sadant sag, att ett Over drivskivan lopande slipduksband är fritt atkomligt utefter hela den Over drivskivan 10- pande delen, sh att foremal av skiftande form och storlek kunna slipas genom att ansattas mot det av skivan understodda slipduksbandet. Fig. 1 shows the grinding device in side view. Figs. 2 and 3 show details. the drawing denotes a e.g. shaft driven by an electric motor 1, the driving spirit of one of the drive pulleys 3 projecting from a shaft bearing resp. the motor 1 supporting machine frame 4 pA such that an abrasive cloth belt running over the drive pulley is freely accessible along the entire 10-drive part of the drive pulley, so that objects of varying shape and size can be ground by being applied to the abrasive cloth belt supported by the pulley.

Slipduksbandet, -vars parter betecknas med 18, Riper Over spannrullen 5, som uppbares av den tvaarmade havstangen 9, vars fran spannrullen vanda del uppbar den ldmpligen installbara motvikten 10. For haystangens 9 uppbarande är anordnad en stoddel 32, vid exemplet a ritningen utf Ord i form av en lagerkonsol, uppstalld a golvet bredvid maskinstativet 4. Med stoddelen 32 är svangbart pa en med drivaxeln 30 parallell tapp 33 forbunden bararmen 6, som fir fastlasbar i onskat installningslage. Dennas ovre 5_nde kan vara direkt utbildad for lagring av havstangen 9, men lampligen Or, som ritningen visar, mellan bararmen 6 och havstangen anordnad en. lank 34. Denna ar svangbart fOrenad med bararmen genom en tapp 36 och fastlasbar i Onskat vinkellage relativt bararmen. Lankens andra ande uppbar pa en vridningstapp 37 havstangen 9. Mellon lanken och haystangen ar insatt en svag fjader 35, som delvis motverkar vikten 10, och som tjanar till att dampa chocken, om bandet 18 skulle brista och vikten svann-as neat. The abrasive cloth band, the parts of which are denoted by 18, Riper Over the tensioning roller 5, which is supported by the heated arm bar 9, from which the usual part of the tensioning roller carried the normally installable counterweight 10. A support part 32 is provided for supporting the haystack 9, in the example of the drawing utf Ord in the form of a bearing bracket, arranged on the floor next to the machine frame 4. The support part 32 is pivotable with the support part 32 connected to a pin 33 parallel to the drive shaft 30, which can be locked in the desired installation position. Its upper end may be directly formed for storage of the sea rod 9, but suitably Or, as the drawing shows, between the bar arm 6 and the sea rod arranged one. lank 34. This is pivotally connected to the bar arm through a pin 36 and lockable in the desired angle relative to the bar arm. The second spirit of the link carried on a pivot pin 37 the sea bar 9. Between the line and the haystack is inserted a weak spring 35, which partially counteracts the weight 10, and which serves to vaporize the shock, if the strap 18 should burst and the weight disappear.

Som framgar av fig. 2 och 3, vilka visa delarna 6 och 34 i 90° elevation frail laget i fig. 1, aro bararmen och lanken forsedda med en bockning i tapparnas 33, 36 axialriktning. Konsolen 32, 6, 34 kommer salunda att std sidledes om planet genom de bada slipbandsparterna 18. Dessa bliva helt fria sa att de efter hela sin langd kunna utnyttjas for slipning av fOremM av skiftande storlek och form. Lanken 34 okar mojligheterna att installa slipduksparterna 18 i onskad vinkel mot vertikalplanet. Bandparterna kunna svangas bade At hoger och vanster relativt drivaxeln 30, sett i fig. 1. Eftersom parterna lopa i varandra motsatta riktningarna kan verkningsriktningen av slipsduksbandet salunda latt omstallas genom svangning av armen 6, am man bada gangerna slipar pa t. ex. den ovre bandparten. As can be seen from Figs. 2 and 3, which show the parts 6 and 34 in the 90 ° elevation frail layer of Fig. 1, the bar arm and the tongue are provided with a bend in the axial direction of the pins 33, 36. The brackets 32, 6, 34 will thus be supported laterally around the plane through the two grinding belt parts 18. These will be completely free so that after their entire length they can be used for grinding objects of varying size and shape. The link 34 increases the possibilities of installing the abrasive cloth parts 18 at the desired angle to the vertical plane. The belt parts can be pivoted both at right and left relative to the drive shaft 30, seen in Fig. 1. Since the parties run in opposite directions, the direction of action of the tie belt can thus be easily adjusted by pivoting the arm 6, if both aisles grind on e.g. the upper band part.

Stodkonsolen 32 har lampligen sadan hojd, att tappen 33 ligger i eller nara horisontalplanet genom drivaxeln 30. The support bracket 32 is suitably of such a height that the pin 33 lies in or near the horizontal plane through the drive shaft 30.
