Description
Technical field
the utility model belongs to Carpesium cernuun and manufactures manufacture field, relates to the device on a kind of Carpesium cernuun broaching fixture, is specially a kind of locking device of Carpesium cernuun broaching fixture.
Background technology
broaching tool is the forming tool for broaching.Tool surface arranges cutter tooth more, and the size and dimension of each row's cutter tooth increases from incision end successively to cutting out end and changes.When broaching motion done by broaching tool, each cutter tooth just cuts certain thickness metal from workpiece, finally obtains required size and dimension.Broaching tool is usually used in batch and processes circular hole, splined hole, keyway, plane and profiled surface etc. in a large amount of production, and productivity ratio is very high.The difference at finished surface position pressed by broaching tool, is divided into inside broach and broach for external bracing; By the difference of force way during work, be divided into broaching tool and push broach.Push broach is usually used in the nibs after calibrating heat treatment.
the structure of broaching tool is relevant with broaching layout with cutting tool shape.Broaching layout is divided into progressive broaching and piecemeal to broach two classes usually.The former is divided into again form and generating broaching; The latter is minute wheel cut and integral wheel cut again.The profile of each cutter tooth of one-tenth form broaching tool is all similar to the net shape of surface to be machined; The cutting tool shape of generating broaching broaching tool is different from workpiece shapes, and the shape of workpiece is formed gradually after being cut successively by each cutter tooth.
the large stack gas turbine wheel disc processing equipment occurred in the market, it is not only heavy, and due to configuration auxiliary equipment poor; so often there will be problem; the carrying out that impact is produced, in the preparation technology of especially current Carpesium cernuun tongue-and-groove, the structure only containing advance and retreat cutter relieving had; when broaching; the meshing degree of index dial and stiff end fluted disc etc. is lower, and the Product Precision making it prepare is not high, or in the product produced; substandard products are more, drastically influence the consecutive production of factory.
if especially do not set the parameter of end-toothed disc and locking device, it easily occurs that the situation of crackle appears in end tooth or the flank of tooth in process of production, the premature failure of index dial or stiff end fluted disc will be caused like this, due in the process of producing, heavy-duty machinery is processed, power required for it and the vibrations of generation are very serious, if locking device does not set, or locking device configuration is bad, converted products may be made to occur the situation coming off or shake off, because cigarette machine is in the process of processing, also the situation along with flue gas overtemperature in cigarette machine occurs, so, cigarette machine the selection of material should be paid special attention to, the security incident that the device avoiding superhigh temperature to bring is damaged and cause.
Summary of the invention
the utility model, just for above technical problem, provides that a kind of structure is simple, security is high, configures the locking device of rational a kind of Carpesium cernuun broaching fixture.
