Abstract
Description
10 15 20 25 30 35 8106231-7 kontinuerlig arbetsoperation. Uppfinningen har för detta ändamål de i de efterföljande patentkraven angivna särdragen. 10 15 20 25 30 35 8106231-7 continuous work operation. The invention has for this purposes specified in the following claims the features.
Uppfinningen kommer i det följande att närmare beskrivas i anslutning till ritningsfigurerna.The invention will be described in more detail below in connection to the drawing figures.
Fig. 1 visar en sidovy av en jigg enligt uppfinningen.Fig. 1 shows a side view of a jig according to the invention.
Fig. 2 visar en planvy av jiggen.Fig. 2 shows a plan view of the jig.
I det visade utföringsexemplet är jiggen 1 uppburen på hjul 2. Jiggen 1 innefattar en rektangulär ram med längsgående balkar 3 och tvärgâende ändbalkar 4. På de båda ändbalkarna 4 uppbäres fritt roterbart lagrade stödrullar 5. Under bear- betningsoperationen vilar ett eller två arbetsstycken, exem- pelvisimatarskruvar; som är antydda med streckprickade linjer 6 på-dessa stödrullar 5. De längsgående balkarna 3 är på sin ovansida försedda med räler 7 för styrning av en vagn 8, som uppbârs av jiggen 1. Denna vagn 8 är försedd med hjul 9, som rullar på nämnda räler 7.In the embodiment shown, the jig 1 is supported on wheels The jig 1 comprises a rectangular frame with longitudinal beams 3 and transverse end beams 4. On the two end beams 4, freely rotatably supported support rollers 5 are supported. the machining operation rests one or two workpieces, e.g. pelvisimatarskruvar; which are indicated by dash dots lines 6 on these support rollers 5. The longitudinal beams 3 are on its upper side provided with rails 7 for guiding a carriage 8, which is supported by the jig 1. This carriage 8 is provided with wheels 9, which rolls on said rails 7.
En kombinerad verktygs- och kamföljarslid 10 är glidbart monterad på vagnens övre del. Sliden 10 kan medelst ett manöverorgan, som i den visade utföringsformen utgörs av en vevmekanism 11 manövreras mot den av jiggen uppburna matar- skruven 6. Ett bearbetningsverktyg (icke visat) såsom exem- pelvis en skärbrännare eller slipskiva är anordnat att monteras på sliden 10. Pâ sliden är vidare ett par kam- följare-12 i form av rullar monterade. Dessa kamföljare 12 är rörligt anordnade på sliden och avståndet emellan dem kan justeras. Orsaken till denna justeringsmöjlighet kommer att framgå av det följande i samband med att anordningens arbetssätt beskrivs.A combined tool and cam follower slide 10 is slidable mounted on the upper part of the trolley. The slide 10 can by means of a operating means, which in the embodiment shown consist of a crank mechanism 11 is operated against the feed carried by the jig. screw 6. A machining tool (not shown) such as pelvis a cutting torch or grinding wheel is arranged to mounted on the slide 10. On the slide are also a pair of cam follower-12 in the form of rollers mounted. These cam followers 12 are movably arranged on the slide and the distance between them can adjusted. The reason for this adjustment option will be appear from the following in connection with the device working methods are described.
- För att bringa matarskruven 6 att rotera under bearbetningen 10 15 20 30 35 8106231-7 är en drivmotor 13 anordnad vid jiggens 1 ena ände. Driv- kraften överförs till skruven 6 genom att motorn 13 är för- sedd med ett hjul 14, som bringas att ligga an mot skruvens axel. Motorn är förskjutbart monterad på en hållare 15, så att dess position på jiggen kan justeras för hjulets 14 an- liggning mot matarskruven 6. Då hjulet 14 roterar överförs drivkraften via friktion till skruven. En motorvariator är anordnad för inreglering av för ändamålet lämplig rotations- hastighet på arbetsstycket. Rotationshastigheten väljs med hänsyn bl.a. till matarskruvens stigning samt den typ av bearbetning som utföres.- To cause the auger 6 to rotate during machining 10 15 20 30 35 8106231-7 is a drive motor 13 arranged at one end of the jig 1. Driving- the power is transmitted to the screw 6 by the motor 13 being seen with a wheel 14, which is brought to abut against the screw shoulder. The motor is slidably mounted on a holder 15, so that its position on the jig can be adjusted for the use of the wheel 14. lying against the feed screw 6. When the wheel 14 rotates, it is transferred the driving force via friction to the screw. An engine variator is arranged for adjusting the rotary shaft suitable for the purpose speed of the workpiece. The rotation speed is selected with consideration i.a. to the pitch of the auger and the type of processing performed.
För att jiggen 1 skall kunna användas för att kalibrera två mot varandra arbetande skruvaxlar är den försedd med anord- ningar 16 för axiell fixering av skruvarna. Dessa anord- ningar utgörs av stàndare på vilka rullar 17 är anbringade.In order for jig 1 to be used to calibrate two mutually opposite screw shafts, it is provided with 16 for axial fixation of the screws. These devices consists of uprights on which rollers 17 are mounted.
För fixering av skruvaxeln 6 bringas en rulle 17 till an- liggning mot en ansats på axeln.To fix the screw shaft 6, a roller 17 is brought to the lying against a shoulder shoulder.
Då jiggen 1 används för bearbetning av en matarskruv 6, placeras skruven först på jiggens stödrullar 5. Om så er- fordras bringas en rulle 17 på anordningen för axiell fixe- ring till anliggning mot en ansats på skruvaxeln. Driv- motorns 13 position på hàllaren 15 justeras så att hjulet 14 ligger an mot axeln. Vagnen 8 förs längs rälerna 7 till en av matarskruvens 6 ändar. Med hjälp av manöverorganet 11 bringas sliden 10 att röra sig mot matarskruven så att kam- rullarna 12 kommer intill skruvgängan. Avståndet mellan kam- rullarna justeras så att de ligger an mot var sin flank på en gänga. Vidare justeras kamrullarnas läge på sliden så att verktyget befinner sig i bearbetningsposition då rullarna ligger an mot gängans flanker. Med hjälp av drivmotorn 13 bringas matarskruven 6 sedan att rotera. Verktyget bringas därvid att kontinuerligt bearbeta skruvgängan genom att kam- rullarna styr vagnens 8 rörelse längs rälerna 7. På detta sätt kan skruven 6 bearbetas i ett enda kontinuerligt arbetsmoment.When the jig 1 is used for machining a feed screw 6, place the screw first on the support rollers 5 of the jig. is required, a roller 17 is brought onto the device for axial fixing. call to abut against a shoulder on the screw shaft. Driving- the position of the motor 13 on the holder 15 is adjusted so that the wheel 14 rests against the shoulder. The carriage 8 is moved along the rails 7 to one of the 6 ends of the auger. By means of the actuator 11 the slide 10 is caused to move against the feed screw so that the cam the rollers 12 come next to the screw thread. The distance between the rollers are adjusted so that they abut each of their flanks a gang. Furthermore, the position of the cam rollers on the slide is adjusted so that the tool is in the machining position when the rollers rests against the flanks of the thread. Using the drive motor 13 then cause the auger 6 to rotate. The tool is brought thereby continuously machining the screw thread by combing the rollers control the movement of the carriage 8 along the rails 7. On this In this way, the screw 6 can be machined in a single continuous manner work steps.
U1 10 8106231-7 Vid t.ex. renovering av matarskruvar till skruvdefibrörer ,kan en skärbrännare monteras på sliden 10. Med denna bränna- re bortskäres skadade eller slitna delar, varefter nytt material, t.ex. bandstål, läggs på under värmning. Därefter utnyttjas brännaren för renskärning av det pålagda materialet.U1 10 8106231-7 At e.g. renovation of feed screws for screw defibrillators , a cutting torch can be mounted on the slide 10. With this torch damaged or worn parts are re-cut, after which new material, e.g. strip steel, is applied during heating. Then the burner is used for clean cutting of the applied the material.
Med anordningen enligt uppfinningen har åstadkommits en jigg, som möjliggör en avsevärd tidsbesparing vid bearbet- ning av matarskruvar jämfört med känd teknik. 'With the device according to the invention a jig, which enables a considerable time saving in processing feed screws compared to the prior art. '
