Abstract
Głowica pomiarowa, zwłaszcza do pomiaru obciążenia przestrzennego noży urabiających na stanowiskach do badania procesu urabiania skał, charakteryzuje się tym, że zbudowana jest z dwóch płyt (1 i 2), pomiędzy którymi rozmieszczone są korzystnie cztery jednoosiowe czujniki nacisku (3), osadzone w narożnikach płyty (2), do której za pomocą przegubu walcowego (7) przymocowana jest zawiasowo płyta uchylna (6), połączona z podstawą uchwytu nożowego (10), do której zamontowany jest uchwyt nożowy (11) z umieszczonym nożem urabiającym (12), pochylonym pod kątem ? względem osi głowicy pomiarowej (19). Sposób pomiaru obciążenia przestrzennego noży urabiających za pomocą głowicy pomiarowej polega na tym, że mierzy się reakcje za pomocą jednoosiowych czujników nacisku (3), korzystnie w czterech punktach podparcia płyty (2), następnie wyznacza się obciążenie noża urabiającego (12) od oporów urabiania zredukowane do wierzchołka ostrza noża (S), które rozkłada się na trzy wzajemnie prostopadłe składowe w postaci siły skrawania Ps prostopadłej do osi głowicy pomiarowej (19) w płaszczyźnie skrawania, siły docisku Pd działającej wzdłuż osi głowicy pomiarowej (19) oraz siły bocznej Pb prostopadłej do płaszczyzny wyznaczonej przez wektory sił Ps i Pd.The measuring head, especially for measuring the spatial load of cutting knives at the stations for testing the rock mining process, is characterized by the fact that it consists of two plates (1 and 2), between which are preferably arranged four uniaxial pressure sensors (3), embedded in the corners a plate (2), to which a swivel plate (6) is hinged to the pivot joint (7), connected to the knife holder base (10), to which the knife holder (11) with a cutter knife (12), inclined at an angle ? relative to the measuring head axis (19). The method of measuring the spatial load of cutting knives by means of a measuring head is that the reactions are measured by means of uniaxial pressure sensors (3), preferably at four plate support points (2), then the load of the cutting knife (12) from the cutting resistance is determined reduced to the tip of the knife blade (S), which is divided into three mutually perpendicular components in the form of cutting force Ps perpendicular to the axis of the measuring head (19) in the cutting plane, pressure force Pd acting along the axis of the measuring head (19) and lateral force Pb perpendicular to plane determined by Ps and Pd force vectors.
