Description
Technical field
The utility model relates to numerically controlled lathe, relates in particular to a kind of numerically controlled lathe and uses the chasing bar of floating.
Background technology
In machine industry, numerically controlled lathe is widely used, and is mainly used to various parts such as processing dish class or axle class.Numerically controlled lathe is being used for the processing criterion inner hole thread, and when the diameter of standard inner hole thread to be processed is smaller, use the cutter of existing standard cutted thread to be difficult to realize, and the price of odd-pitch screw cutter is relatively costly, make processing cost increase, in that the not high workpiece of processing added value is adopted the odd-pitch screw cutter obviously is uneconomic, does not reach the purpose of cost efficiency.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, unsteady chasing bar of service-strong numerically controlled lathe usefulness.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of numerically controlled lathe comprises quick chuck, buoyancy body, spring, guide post, cover plate and location cylindrical that screw tap is installed with the chasing bar of floating, and the stiff end of described quick chuck is fixed on an end of buoyancy body, and the other end of described buoyancy body is a circular cylindrical cavity; Described guide post is the stepped cylinder of two-stage, the cylindrical diameter of the first order of described guide post is greater than the cylindrical diameter in the second level, the circular cylindrical cavity of described buoyancy body is sleeved on the guide post, and the first order cylinder of guide post is fully in the circular cylindrical cavity of buoyancy body; Cover plate is sleeved on the cylinder of the guide post second level, and is fixed on the lateral surface of the circular cylindrical cavity of stating buoyancy body; Described spring housing is contained on the cylinder of the guide post second level, and fully in the circular cylindrical cavity of buoyancy body; The internal diameter of described spring is less than the cylindrical diameter of the first order of guide post, and the external diameter of spring is greater than the internal diameter of cover plate; Described location cylindrical is fixed on the cylindrical side, the second level of guide post, and the axis of described quick chuck, guide post and location cylindrical is parallel with main-shaft axis.
Described buoyancy body is provided with guide finger, is provided with on guide post and the suitable gathering sill of described guide finger; The design of guide finger and gathering sill, the slip in buoyancy body plays position-limiting action to guide post.When design, guarantee that the slip of guide finger in gathering sill is light, and the slip of guide post in buoyancy body is light.
Described location cylindrical is provided with the flat filament structure.
Described buoyancy body is provided with positioning spline, and described quick chuck is provided with the keyway suitable with positioning spline, locatees by positioning key between described buoyancy body and the quick chuck.
Described numerically controlled lathe is with floating chasing bar in use, needs will locate earlier cylindrical and packs in the installing hole of the endoporus tool rest on the lathe cutterhead, uses the screw in compression flat filament then, and is parallel with the axis that guarantees screw tap and main shaft.Before the lathe tapping, with screw tap pack into the corresponding quick chuck of screw tap on, with housing screw screw tap is fixed again; During the lathe tapping, use machine tool dragging plate that screw tap is adjusted to the alignment of shafts, start main shaft, planker drives described unsteady chasing bar to process than little about 10% the amount of feeding of thread pitch to be processed; After tapping is finished, the main shaft counter-rotating, described unsteady chasing bar is return, the tapping process finishing.Described unsteady chasing bar need be determined the response time of main shaft rotating before use, and the feeding distance of machine tool dragging plate guaranteed that screw tap is not twisted off when this corresponding time of basis was determined tapping when programming.Quick chuck is installed the part of screw tap, can be according to the handle designs of screw tap.
Beneficial effect: a kind of numerically controlled lathe that the utility model provides is with the chasing bar of floating, simple in structure, use reliable, and can be according to the different suitable quick chucks of screw tap design, its scope of application is wide; Not only can guarantee machining accuracy, the production efficiency of workpiece, and can reduce production cost of products, especially be fit to produce in batches.
