Description
Technical field
The present invention relates to Metal Cutting field, particularly relate to a kind of material feed clamping mechanism and method thereof of metal cutting circular sawing machine.
Background technology
Metal cutting circular sawing machine is a kind of metal cutter being specifically designed to incising circular bar.Its cutting speed is fast, and cutting speed is more than 4 times of general NC band sawing machine; Precision is high, and length tolerance is at ± 0.05mm, and two cut surface parallelism tolerances are at ± 0.1mm, and squareness tolerance is at ± 0.06mm, and tangent plane fineness generally can reach more than 0.8; Cutting expense is low, and cutting cost saves more than 1/4th than general NC band sawing machine; Automaticity is high, and Full computer numerical control operates, and material is loaded onto after bin starts lathe, and circular sawing machine can the cutting of automated exchanged cutter material, until till on bin, material has cut or reaches the blanking-quantity that presets; Safe and reliable, greatly reduce the industrial accident because handling material produces.
Material feed clamping mechanism is the important component part of metal annular sawing machine, it must have larger chucking power, make workpiece not slide when cutting, roll or vibrate, want in addition to detect workpiece accurately and whether clamp, particularly uneven for thickness or have bending bar.
At present, the jam accuracy of detection of the material feed clamping mechanism on metal cutting circular sawing machine to bar is not high, and sometimes can can't detect thickness uneven or have the jam of bending bar, occur false alarm, impact normally works.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of metal cutting circular sawing machine material feed clamping mechanism and method thereof are provided.
Metal cutting circular sawing machine material feed clamping mechanism comprises grain-clamping table and pressing plate, and hydraulic cylinder, hydraulic cylinder installing rack, heilical spring bearing, balance pivot, lever, lever back-moving spring, close to inductor installing rack, close to inductor, cover plate; Hydraulic cylinder is secured by bolts on hydraulic cylinder installing rack, the piston rod of hydraulic cylinder connects pressing plate, hydraulic cylinder installing rack is secured by bolts on grain-clamping table, lever is connected with pressing plate by balance pivot, heilical spring bearing is fixed on lever, be secured by bolts on pressing plate close to inductor installing rack, lever back-moving spring is connected with lever with close to inductor installing rack respectively, is fixed on close on inductor installing rack close to inductor and cover plate.
Described heilical spring bearing outer ring exceeds platen edge 2 ~ 3mm.
Metal cutting circular sawing machine material feed clamping method comprises the steps:
1) be pushed between grain-clamping table and pressing plate by workpiece, the piston of hydraulic cylinder promotes pressing plate by Work-sheet pressing;
2) heilical spring bearing outer ring with by the absorption surface clamped, heilical spring bearing is forced to inside pressing plate and is moved, drive lever rotate around balance pivot, the ratio L2/L1=3 on lever both sides, realize heilical spring bearing move distance be exaggerated 3 times;
3) judge that whether workpiece is clamped close to inductor by the position detecting lever end, if clamped, carry out next step action.
Use the present invention, structure is simple, installs, easy to maintenance, and Automated condtrol, chucking power is large.During clamping work pieces, workpiece contacts with the outer ring of heilical spring bearing, and heilical spring bearing drives leverage, is determined the jam of workpiece close to inductor by the motion detecting leverage.Because heilical spring bearing outer ring exceeds platen edge certain distance L, so accurately can detect the jam that cylindricity is less than the bar of L, the bar overcoming original clamp system larger to cylindricity detects coarse shortcoming.
