Abstract
The technical problems to be solved in the utility model is to provide a kind of gear finish turning frock that can reduce gear workpieces manufacturing procedure, it comprises mandrel, butterfly spring sub-assembly, spill pad, bolt, described mandrel is multidiameter, one end of described mandrel is outwards provided with butterfly spring sub-assembly successively from round platform portion, spill pad and bolt, described spill pad and bolt are arranged on the end face of mandrel, the diameter of described spill pad is greater than the diameter of end face of mandrel and is less than the diameter of butterfly spring sub-assembly, the flange of described spill pad periphery contacts with butterfly spring sub-assembly and coordinates.This frock is easy to use, can fix by tightening, unclamping nut and take out gear workpieces, and disk spring sub-assembly is changed conveniently simultaneously.
Description
Technical field
The utility model relates to Gear Processing field, is especially a kind ofly convenient to the frock of gear being carried out to numerical control finish turning.
Background technology
in prior art, added to gear workpieces man-hour, because gear workpieces shape is special, be not easy to fix, the operation of therefore processing is various, generally includes hole end surface in numerical control lathe, and---flat other end---plain grinding end face---fine turning outer circle four procedure, such production efficiency is obviously lower.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of gear finish turning frock that can reduce gear workpieces manufacturing procedure.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of gear finish turning frock, comprise mandrel, butterfly spring sub-assembly, spill pad, bolt, described mandrel is multidiameter, one end of described mandrel is outwards provided with butterfly spring sub-assembly, spill pad and bolt successively from round platform portion, described spill pad and bolt are arranged on the end face of mandrel, the diameter of described spill pad is greater than the diameter of end face of mandrel and is less than the diameter of butterfly spring sub-assembly, and the flange of described spill pad periphery contacts with butterfly spring sub-assembly and coordinates.
The using method of technique scheme is, first clamp mandrel with scroll chuck, again gear workpieces cover is installed on disk spring sub-assembly, then tight a bolt and promote spill pad compression butterfly spring sub-assembly, butterfly spring sub-assembly is out of shape and the axis hole of swelling gear workpieces, thus gear workpieces is fixed, this makes it possible to process the end face of gear workpieces and cylindrical, after gear workpieces machines, looser a bolt, butterfly spring sub-assembly elasticity is recovered, just can take out gear workpieces.This frock is easy to use, and by tightening, unclamping nut, disk spring sub-assembly is changed conveniently simultaneously.
Preferably, described butterfly spring sub-assembly is combined by the butterfly spring of multiple band radial groove, the same position of the butterfly spring of multiple band radial groove is equipped with a manhole, a bearing pin is housed in the manhole of the butterfly spring of multiple band radial groove.
Preferably, the medial extremity of described bearing pin and the round platform portion of mandrel are threaded connection.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is core shaft structure schematic diagram of the present utility model;
Fig. 3 is butterfly spring structural representation of the present utility model.
Detailed description of the invention
As Fig. 1, 2, shown in 3, preferred embodiment of the present utility model is: a kind of gear finish turning frock, comprise mandrel 1, butterfly spring sub-assembly 2, spill pad 4, bolt 5, described mandrel 1 is multidiameter, one end of described mandrel 1 is outwards provided with butterfly spring sub-assembly 2 successively from round platform portion 11, spill pad 4 and bolt 5, described spill pad 4 and bolt 5 are arranged on the end face of mandrel 1, the diameter of described spill pad 4 is greater than the diameter of mandrel 1 end face and is less than the diameter of butterfly spring sub-assembly 2, the flange of described spill pad 4 periphery contacts with butterfly spring sub-assembly 2 and coordinates, described butterfly spring sub-assembly 2 is combined by the butterfly spring of multiple band radial groove, the same position of the butterfly spring of multiple band radial groove is equipped with a manhole 21, a bearing pin 3 is housed in the manhole 21 of the butterfly spring of multiple band radial groove, and the medial extremity of described bearing pin 3 and the round platform portion 11 of mandrel 1 are threaded connection
The using method of technique scheme is, first with scroll chuck clamping mandrel 1, again gear workpieces 6 cover is installed on disk spring sub-assembly 2, then the 5 promotion spill pads 4 that tight a bolt compress butterfly spring sub-assembly 2, butterfly spring sub-assembly 2 is out of shape and the axis hole of swelling gear workpieces 6, thus gear workpieces 6 is fixed, this makes it possible to process the end face of gear workpieces 6 and cylindrical, after gear workpieces 6 machines, looser a bolt 5, butterfly spring sub-assembly 2 elasticity is recovered, just can take out gear workpieces 6.This frock is easy to use, by tightening, unclamping nut, according to the size of different workpieces endoporus, can change different disk spring sub-assemblies simultaneously.
