Abstract

Przyrząd do pomiaru obciążeń dynamicznych noży skrawających organów roboczych, zwłaszcza kombajnów górniczych charakteryzuje się tym, że zbudowany jest z podstawy uchwytu (7), na której osadzony jest korpus uchwytu (1) z cylindrycznym gniazdem (5) o osi pokrywającej się z osią podłużną noża (9) osadzonego w tulei napinającej (3) połączonej z korpusem uchwytu (1) za pomocą złącza gwintowego (6), przy czym wewnątrz cylindrycznego gniazda (5) osadzony jest czujnik siły (4) zamocowany za pomocą tulei napinającej (3) poprzez kołnierz dociskowy (2). Sposób pomiaru obciążeń dynamicznych noży skrawających organów roboczych zwłaszcza kombajnów górniczych polega na tym, że mierzy się korzystnie trzy składowe obciążenia noża (9) przy użyciu czujnika siły (4) w układzie współrzędnych czujnika XYZ, po czym dokonuje się transformacji tych sił na siłę skrawania Ps, siłę docisku Pd i siłę boczną Pb w układzie współrzędnych XSYSZS związanym z trajektorią ostrza noża (9) w trakcie urabiania skały organem roboczym maszyny urabiającej i zaczepionym w wierzchołku ostrza noża (9), w ten sposób, że siła skrawania jest styczna do toru ruchu noża (9), siła docisku jest prostopadła do dna bruzdy, natomiast siła boczna jest prostopadła do siły skrawania i siły docisku.The device for measuring dynamic loads of cutting knives of working organs, especially mining combines is characterized by the fact that it consists of a chuck base (7) on which the chuck body (1) with a cylindrical seat (5) with the axis coinciding with the longitudinal axis of the knife is mounted. (9) embedded in the tensioning sleeve (3) connected to the handle body (1) by means of a threaded joint (6), where inside the cylindrical seat (5) a force sensor (4) is mounted, which is attached by means of the tensioning sleeve (3) through the collar pressure (2). The method of measuring dynamic loads of cutting knives of working organs, especially mining combines is based on the fact that preferably three components of the knife load (9) are measured using a force sensor (4) in the coordinate system of the XYZ sensor, after which these forces are transformed into the cutting force Ps , clamping force Pd and lateral force Pb in the XSYSZS coordinate system related to the knife blade trajectory (9) during rock mining with the working organ of the cutting machine and attached to the tip of the knife blade (9), in such a way that the cutting force is tangent to the path of movement knife (9), the clamping force is perpendicular to the bottom of the furrow, while the lateral force is perpendicular to the cutting force and clamping force.
