Description
Vynález rieši zariadenie na meranie upínacej sily, najma pre rotačné upínače.The invention provides a clamping force measuring device, in particular for rotary clamps.
Doteraz známe zariadenia na meranie upínacej sily sa skladajú z rebrovitého telesa, ktorého deformácia úměrná velkosti upínacích sil sa meria pomocou tenzometrov. Elektrický signál sa po přenose z rotujúceho vřetena spracúva v meracom mostíku.The prior art clamping force measuring devices consist of a ribbed body whose deformation proportional to the size of the clamping forces is measured by strain gauges. The electrical signal is processed in the measuring bridge after being transmitted from the rotating spindle.
K ich nevýhodám patří najma to, že majú poměrně velké rozměry a tenzometre nie sú chráněné voči mechanickému poškodeniu.Their disadvantages include, in particular, that they have relatively large dimensions and strain gauges are not protected against mechanical damage.
Uvedené nevýhody zmierňuje zariadenie na meranie upínacej sily, najma pre rotačné upínače, podía vynálezu, ktorého podstatou je, že v rotačně symetrickom základnom telese, opatrenom aspoň jednou opornou plochou pre dotyk s čelusťami upínača, je v radiálnom smere vytvořené vybranie, do' ktorého je uložené pružné teleso opatrené dotykovou plochou pre dotyk s če1’usťou upínača, pričom deformačně teleso je opatřené aspoň jedným tenzometrom.The clamping force measuring device, in particular for rotary clamps according to the invention, alleviates these disadvantages, the principle being that in a rotationally symmetrical base body provided with at least one support surface for contacting the clamp jaws, a recess is formed in the radial direction into which a resilient body having a contact surface for contacting the clamp jaw, wherein the deformation body is provided with at least one strain gauge.
Výhodou zariadenia na meranie upínacej sily, najma pre rotačné upínače podía vynálezu je to, že má poměrně malé rozměry a jednoduchú konštrukciu. Dalšou jeho výhodou je, že tenzometre, ktoré sú vsadené do zariadenia sú chráněné voči mechanickému poškodeniu.The advantage of the clamping force measuring device, in particular for the rotary clamps according to the invention, is that it has relatively small dimensions and simple construction. Another advantage is that the strain gauges that are inserted into the device are protected against mechanical damage.
Zariadenie na meranie upínacej sily, naj2 má pre rotačné upínače najde uplatnenie predovšetkým pri meraní upínacích sil rotačných upínačov, a to tak za kludu, ako aj za otáčok.The clamping force measuring device, in particular for rotary clamps, finds application particularly in measuring clamping forces of rotary clamps, both at rest and at speed.
Na pripojenom obrázku je znázorněný příklad vybudovania vynálezu v pozdížnom a priečnom řeze. Zariadenie na meranie upínacej sily, najma pre rotačné upínače sa skládá zo základného telesa 10, deformačného telesa 20 a tenzometra 30. V základnom telese 10, ktoré má vytvořené oporné plochy 111, je radiálně vložené deformačně teleso 20, ktoré je z časti válcové. Na deformačnom telese 20 je vytvořený jednak krčok 22 a jednak dotykové plochy 211. Krčok 22 deformačného telesa 20 je opatřený aspoň jedným tenzometrom 30. Na telese 10 je vytvořená osadená plocha 12 pre upevnenie zariadenia na přenos měrných údajov z rotujúceho vřetena.The attached figure shows an example of a longitudinal and cross-sectional construction of the invention. The clamping force measuring device, in particular for the rotary clamps, comprises a base body 10, a deformation body 20 and a strain gauge 30. In the base body 10 having supporting surfaces 111, a deformation body 20, which is partly cylindrical, is inserted radially. The neck 22 of the deformation body 20 is provided with at least one strain gauge 30. On the body 10 a stepped surface 12 is provided for fastening the data transmission device from the rotating spindle.
Pri meraní upínacích sil sa snímač upne svojimi opornými plochami 111 a dotykovými plochami 211 do upínača tak, aby sa deformačně teleso 20 dostalo oproti jednej z čelustí upínača 40. Upínacia sila vyvolá deformáciu deformačného telesa 20, ktorej velkost sa meria tenzometrom 30 známým sposobom. Pri meraní upínacích sil za otáčok sa elektrický signál prenáša z rotujúceho vřetena tiež známým spůsobom.To measure the clamping forces, the sensor is clamped with its abutment surfaces 111 and contact surfaces 211 in the clamp so that the deformation body 20 is positioned against one of the jaws of the clamp 40. The clamping force causes deformation of the deformation body 20. When measuring the clamping forces per revolution, the electrical signal is transmitted from the rotating spindle also in a known manner.
