Description
Technical field
The present invention relates to a kind of provision for disengagement, especially a kind of heat rises the provision for disengagement of handle of a knife breaking.
Background technology
At aviation field, there is the part of a large amount of difficult-to-machine material, as high-temperature alloy material part, titanium alloy material part, hardened steel material parts, the part of these materials is very harsh to the requirement of lathe rigidity, fixture rigidity, handle of a knife rigidity and cutter rigidity in process, and the stability that the machine of part adds state decides surface quality and the dimensional accuracy of part.In order to excellent instrument rigidity and stability can be obtained in part process, the high rigidity handle of a knife of cutter manufacture producer specialized designs, instant heating rises handle of a knife, and this handle of a knife when mounted, is heated handle of a knife by special equipment, after Cutting tool installation manner hole thermal expansion on handle of a knife, mounting cutter, then cools shank portion, and Cutting tool installation manner hole is by cold events, cutter is clamped, and improves the clamping rigidity of cutter.Aeronautical manufacture factory adds man-hour also for lathe configures this kind of handle of a knife at part, and obtains the accreditation of aeronautical manufacture factory in the heat performance of rising in handle of a knife application process.But in application process, find to there is certain problem, while improve cutter clamping rigidity, weaken the toughness of tooling system.Sometimes in process, cutter buffering not in time, easily causes fractureing of cutter, and the extremely difficult taking-up of part in handle of a knife stayed by the cutter fractureed.Traditional method adopts electrical-chemistry method, destroyed by the shaft portion electrode in handle of a knife, easily occurs the residual of knife bar or the chemical attack to handle of a knife clamping hole sidewall in this process, finally causes heat to rise the decline of scrapping of handle of a knife or precision.
Summary of the invention
The object of this invention is to provide a kind of heat to rise the provision for disengagement of handle of a knife breaking, can the quick and safe ground pulling-out of cutter that fractures that will stay heat and rise in handle of a knife, ensure that heat handle of a knife clamping hole of rising is not damaged, handle of a knife clamp precision is intact.
Technical scheme of the present invention is, the rise provision for disengagement of handle of a knife breaking of described heat comprises pedestal, pressing plate, compression spring, thimble, elastic card claw, described pressing plate is arranged on pedestal, pressing plate is provided with elastic card claw, described elastic card claw can radially move, the heat handle of a knife that rises is placed on pressing plate, the rise taper installed surface of handle of a knife of heat is positioned at pedestal, breaking position is positioned at outside, elastic card claw radially moves and is stuck in heat and rises in the cannelure of handle of a knife, compression spring is arranged in pedestal, compression spring is pushed down in thimble one end, the other end is withstood on breaking by the hole of hot handle of a knife inside of rising.
For ensureing that heat rises the installation fastness of handle of a knife, pedestal is provided with cone of support, described cone of support is provided with inner conical surface, and to rise the installation cone match of handle of a knife with heat.Consider that the different heat handle of a knife that rises has the conical surface of different parameters, cone of support is arranged to independently parts, is fixedly mounted on pedestal, its inner conical surface handle of a knife that can rise according to different heat is arranged; Have thrust cylinder at pedestal internal fixtion, compression spring is arranged on thrust cylinder interior, and thimble stretches out the stability ensureing compression spring work from thrust cylinder top; Thrust cylinder is also provided with can perpendicular to the control lever of thimble axial-movement, described control lever extends inwardly to thrust cylinder interior, extend out to pedestal outside, described control lever can push down compression spring, unload split off cutter time, outside extraction control lever, just can realize the force effect of thimble to breaking.
At work, handle of a knife that heat is risen install described in provision for disengagement on, the heat installed surface of handle of a knife that rises coordinates with the inner conical surface of cone of support, and elastic card claw blocks heat and to rise the annular slot of handle of a knife, spring and breaking and withstand pressure respectively in thimble two ends.Described provision for disengagement is arranged on the heat handle of a knife heat that rises to rise on means for positioning cutting tool workbench, heats shank portion, handle of a knife clamping hole becomes large, and doubling breaking tool applies thrust upwards, and the cutter that will fracture upwards is released and departed from heat and to rise handle of a knife.The present invention makes handle of a knife keep vertical direction, attitude stabilization in dismounting breaking process; Described elastic card claw blocks handle of a knife in the process of dismounting breaking, ensures that handle of a knife is stablized; The present invention to be risen means for positioning cutting tool workbench by frame for movement and heat, dismantles breaking, to heat rise that handle of a knife do not exist that chemical attack and impulsive force bring damage, ensure that heat handle of a knife clamping hole of rising is not damaged, handle of a knife clamp precision is intact, rational in infrastructure, easy and simple to handle.
