Abstract
Účelom vynálezu je zabezpečenie zvýšenia tuhosti zariadenia. Uvedeného účelu sa dosiahne tým, že oporná konzola, v ktorej je upevněný oporný kotúč a vřeteník, v ktorom je uložený lapovací kotúč, sú navzájom spojené nosníkom.The purpose of the invention is to provide an increase rigidity of the device. That purpose is it reaches by the support bracket in which the support disk and headstock, v where the lapping disk is placed, are in mutual contact connected by a beam.
Description
Vynález' rieši zariadenie s vodorovnou osou rotácle na brúsenie a lapovanie guliek.The invention provides a device with a horizontal axis rotating for grinding and lapping bullets.
Známe konštrukcie lapovacích strojov s vodorovnou osou vřetena majú nevýhodu v tom, že majú mechanicky vysúvanú pinolu a z dovodu nesúvislosti rámu jeho malú tuhost, čo má nepriaznivý vplyv na kvalitu opracovania lapovaných guliek.The known designs of lapping machines with a horizontal spindle axis have the disadvantage that they have a mechanically extending quill and, due to the discontinuity of the frame, its low stiffness, which adversely affects the machining quality of the lapped balls.
Uvedené nevýhody odstráňuje zariadenie s vodorovnou osou rotácie na brúsenie a lapovanie guliek pozostávajúce z lapovacieho kotúča, uloženého prostrednictvom príruby, upevnenej na vřetene vo vřeteníku a oporného kotúča, upevněného na opornej konzole, podlá vynálezu, ktorého podstata spočívá v tom, že oporná konzola a vřeteník sú navzájom spojené nosníkom.The above-mentioned disadvantages are eliminated by a device with a horizontal axis of rotation for grinding and lapping of balls consisting of a lapping disc supported by a flange mounted on a spindle in a headstock and a supporting disc mounted on a support bracket according to the invention. are connected to each other by a beam.
Výhody zariadenia podlá vynálezu sú v tom, že má vysokú tuhost, čo kladné vplýva na kvalitu opracovania lapovaných guliek.The advantages of the device according to the invention are that it has a high rigidity, which positively affects the quality of the lapped ball processing.
Příklad prevedenia zariadenia je v čiastočnom řeze znázorněný na obrázku.An exemplary embodiment of the device is shown in partial section in the figure.
Na podstavu 1 je upevněný vřeteník 2, v ktorom sa priamočiaro pohybuje hydraulicky ovládaná pinola 3. V pinole 3 je na přesných valivých ložiskách uložené vřeteno 4, ktoré nesie přírubu 5 s brusným alebo lapovacím kotúčom 8. Otáčky vřetena 4 sú plynule regulovatelné tyrlstorovým regulátorom otáčok v spojení s jednosměrným regulačným motorom 7. Oproti vřeteníku 2 je připevněné teleso opornej konzoly 8 spolu s oporným kotúčom 9. Telesá vreteníka 2 a opornej konzoly 8 sú spojené mohutným nosníkom 10 a spolu s podstavou 1 tak tvoria tuhý rám stroja. Vedla podstavy 1 stroja je postavený zásobník guliek, ktorý sa skládá z podstavy 11 zásobníka unášacieho kotúča 12, ktorý je zvisle a vodorovné prestavitelný a jeho otáčky sú plynule regulovatelné pomocou elektrického servopohonu. Gulky sú otáčavým pohybom unášacieho kotúča zásobníka 12 dopravované cez vstupný žlab medzi brúsny alebo lapovací kotúč 6 a oporný kotúč 9. Gulky obehnú v sústredných drážkách, vytvořených v kotúčoch 8, 9 a cez výstupný žlab sa vrátia do zásobníka a celý cyklus sa opakuje.A spindle 2 is mounted on the base 1 in which the hydraulically operated quill 3 moves in a straight line. In the quill 3, a spindle 4 is supported on precision rolling bearings carrying a flange 5 with an abrasive or lapping disc 8. Spindle speed 4 is infinitely adjustable The support bracket body 8, together with the support disk 9, is mounted opposite the headstock 2. The body of the headstock 2 and the support bracket 8 are connected by a massive beam 10 and together with the base 1 form a rigid machine frame. Next to the machine base 1 there is a bullet magazine consisting of a base 11 of the carrier disc 12, which is vertically and horizontally adjustable and its speed is continuously adjustable by means of an electric actuator. The bullets are rotated by the drive disc of the magazine 12 through the inlet trough between the grinding or lapping disc 6 and the support disc 9. The bullets circulate in concentric grooves formed in the discs 8, 9 and return through the outlet trough to the magazine and repeat the entire cycle.
