Rakenduskõrghariduseõppe lõputöö Tehnotroonika õppekaval Lõputöö eesmärgiks on projekteerida saekaatri ettevõttele mitmikspindlilise puurpea lahendust, mille ülesandeks on puurida korraga neli ava puidust detaili. Ettevõttel on soov hakata tootma uut toodet. Antud puurpea lahendus lihtsustaks ja kiirendaks plaanitava toote tootmist ja annaks ettevõttele konkurentide ees turueelise tulenevalt võimalikust madalast tootehinnast. Prototüübi valmistamiseks kasutati kolmemõõtmelist raalprojekteerimiseks mõeldud CAD tarkvara SolidWorks. Projekteerimist alustati hammasrataste valikust, lähtudes geomeetrilisest arvutusest. Tulenevalt hammasratasest valiti sobilikud laagrid, võllid, prismaliistud ja plaadid. Komponentide sobivust kontrolliti erinevate arvutustega, alustades laagrite elueast ja lõpetades prismaliistu lubatava pöördemomendiga. Reaalne puurpea koost on tegemata ja hetke seisuga on tegemist ainult projektiga. Vajalike detailide soetamise korral on võimalik katsetada neljaspindlilise puurpea toimimist. The aim of the thesis is to design a multi-surface drill head solution for the sawmill company, the task of drill head is to drill four openings to wooden detail at once. The company wants to start producing a new product. This drillhead solution would simplify and accelerate the production of the planned product and give the company a market advantage over competitors due to the possible low product price. The prototype was manufactured using SolidWorks, a three-dimensional CAD (computeraided engineering) software designed to create visual models. The design was started from a range of gears based on a geometric calculation. Due to the gears, suitable bearings, shafts, parallel keys and plates were selected. The compatibility of the components was checked by various calculations, starting with the lifetime of the bearings and ending with the admissable torque of the parallel keys. A real drill head assembly has not been completed and at the moment it is only a project. If necessary, it is possible to test the operation of the four-spindle drill head. |
