The invention relates to a safe bone sawing
machine with high
cutting accuracy. The safe bone sawing
machine with high
cutting accuracy comprises a base, a
machine frame, a platform, a fixed-length plate and a saw blade. The safe bone sawing machine with high
cutting accuracy further comprises a propulsion mechanism and two positioning mechanisms; each of the positioning mechanisms comprises a first driving
assembly, a first connecting rod, a screw rod, a driving sleeve, two bearings, two second connecting rods and two connecting sleeves; the propulsion mechanism comprises a second driving
assembly and two propulsion assemblies; each of the propulsion assemblies comprises a push board, a swing lever and a second transmission rod; and the first driving
assembly comprises a second motor, a gear and an annular rack. According to the safe bone sawing machine with high cutting accuracy, a meat product can be automatically pushed toward the direction of the saw blade by the propulsion mechanism, so that, the probability of contact between an operator's palm and the saw blade is reduced so as to improve safety of the bone sawing machine; moreover, the fixed-length plate can be fixed by the positioning mechanisms, so that, the probability of offset of the fixed-length plate is reduced so as to improve quality of meat products
cut by the bone sawing machine.
