Abstract

The invention aims at providing a gear finish turning tool capable of reducing the machining working procedure of a gear workpiece. The gear finish turning tool comprises a mandrel, a belleville spring combined part, a concave gasket and a bolt, wherein the mandrel is a stepped shaft, one end of the mandrel is sequentially provided with the belleville spring combined part, the concave gasket and the bolt from a circular truncated cone part to the outside, the concave gasket and the bolt are installed at the end face of the mandrel, the diameter of the concave gasket is larger than that of the end face of the mandrel and smaller than that of the belleville spring combined part, and a flange of the periphery of the concave gasket is matched with the belleville spring combined part in a contacting mode. The tool is convenient to use, the gear workpiece can be fixed and taken out by screwing or unscrewing a nut, and the belleville spring combined part is convenient to replace.

Description

A kind of gear finish turning frock
Technical field
The present invention relates to Gear Processing field, be 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.
Summary of the invention
The technical problem to be solved in the present invention 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, technical scheme of the present invention 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 invention;
Fig. 2 is core shaft structure schematic diagram of the present invention;
Fig. 3 is butterfly spring structural representation of the present invention.
Detailed description of the invention
As Fig. 1, 2, shown in 3, the preferred embodiments of the present invention are: 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.
