Description
Technical field
This utility model relates to spiral bevel gear Milling Machining technology, is related specifically to a kind of helical disk gear Milling Machining fixture.
Background technology
Transmission efficiency is high, gear ratio is stable, circular arc overlap coefficient big and bearing capacity high, is widely used in each mechanical field owing to it has for helical disk gear.During manufacturing helical disk gear, profile to be produced shows conical surface annulus with helical disk gear, then is fixed on by conical surface annulus on gear-hobbing machine or tooth milling machine work top, then, carries out mill teeth or gear hobbing process.Owing to the face of mill teeth or gear hobbing process is on the surface of conical surface annulus, therefore, can only be clamped by the bottom of conical surface annulus or side.In prior art spiral bevel gear Milling Machining clamp method uses, scroll chuck clamps conical surface annulus, i.e. after conical surface annulus is placed on scroll chuck, from inside to outside pull three-jaw card so that three-jaw card clamps the bore section of conical surface annulus, thus is fixed on work top by conical surface annulus blank.But, due to interior scroll chuck conical surface annulus blank it may happen that axial dipole field so that the size of the spiral bevel gear processed can not meet design requirement.Obviously, prior art spiral bevel gear Milling Machining clamp method also exists it may happen that axial dipole field when blank clamps, and the size of the spiral bevel gear processed can not meet the problems such as design requirement.
Summary of the invention
It may happen that axial dipole field when the blank existed for solving prior art spiral bevel gear Milling Machining clamp method clamps, the size of the spiral bevel gear processed can not meet the problems such as design requirement, the utility model proposes a kind of helical disk gear rolling clamp for machining.
This utility model helical disk gear rolling clamp for machining, including base plate, positioning seat, rise block and locating dowel；Annular base plate and cylindrical positioning seat are coaxially fixed on platen face, and one end circumference of positioning seat is evenly arranged with the opening accommodating the block that rises, and, excircle is additionally provided with the annular groove accommodating turn；Three blocks that rise are arranged on positioning seat opening part, and can slide in opening, the circle that the lateral surface of three blocks that rise is constituted with conical surface annulus blank endoporus formed objects lacks face, and upper surface is provided with evagination step, and medial surface composition is round with the tapering that the back draught of locating dowel end cylindrical matches lacks face；Locating dowel is sleeved on positioning seat endoporus, and is connected with cylinder piston.
The Advantageous Effects of this utility model helical disk gear rolling clamp for machining is firmly to be fixed on the work top of lathe by conical surface annulus blank, and, easy to loading and unloading.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of the conical surface annulus blank of processing helical disk gear；
Accompanying drawing 2 is the schematic three dimensional views of this utility model helical disk gear rolling clamp for machining clamping blank.
With specific embodiment, this utility model helical disk gear rolling clamp for machining is further described below in conjunction with the accompanying drawings.
Detailed description of the invention
Accompanying drawing 1 is the schematic diagram of the conical surface annulus blank of processing helical disk gear, as seen from the figure, during manufacturing helical disk gear, profile to be produced shows conical surface annulus with helical disk gear, again conical surface annulus is fixed on gear-hobbing machine or tooth milling machine work top, then, mill teeth or gear hobbing process are carried out.Owing to the face of mill teeth or gear hobbing process is on the surface of conical surface annulus, therefore, can only be clamped by the bottom of conical surface annulus or side.In prior art spiral bevel gear Milling Machining clamp method uses, scroll chuck clamps conical surface annulus, i.e. after conical surface annulus is placed on scroll chuck, from inside to outside pull three-jaw card so that three-jaw card clamps the bore section of conical surface annulus, thus is fixed on work top by conical surface annulus blank.But, due to interior scroll chuck conical surface annulus blank it may happen that axial dipole field so that the size of the spiral bevel gear processed can not meet design requirement.
Accompanying drawing 2 is the schematic three dimensional views of this utility model helical disk gear rolling clamp for machining clamping blank, and in figure, 1 is base plate, and 2 is positioning seat, and 3 is the block that rises, and 4 is lead, and A is conical surface annulus blank.As seen from the figure, this utility model helical disk gear rolling clamp for machining, this utility model helical disk gear rolling clamp for machining, including base plate 1, positioning seat 2, rise block 3 and locating dowel 4；Annular base plate 1 and cylindrical positioning seat 2 are coaxially fixed on platen face, and one end circumference of positioning seat 2 is evenly arranged with the opening accommodating the block 3 that rises, and, excircle is additionally provided with receiving turn annular groove；Three blocks 3 that rise are arranged on positioning seat 2 opening part, and can slide in opening, the circle that the lateral surface of three blocks 3 that rise is constituted with conical surface annulus blank endoporus formed objects lacks face, and upper surface is provided with evagination step, and medial surface composition is round with the tapering that the back draught of locating dowel 4 end cylindrical matches lacks face；Locating dowel 4 is sleeved on positioning seat 2 endoporus, and is connected with cylinder piston.When specifically used, three blocks that rise shrink to direction, the center of circle under the effect of turn so that evagination step inwardly shrinks, and the diameter of a circle of composition is less than the internal diameter of conical surface annulus blank.Conical surface annulus blank is placed on the outside of the circle that the block that rises is constituted, open cylinder, lead moves down under the drive of cylinder piston, owing to the block medial surface that rises constitutes the scarce face of tapering circle that the back draught with locating dowel end cylindrical matches, along with moving downward of lead, the block that rises outwards runs, the endoporus of conical surface annulus blank is gripped by the block lateral surface that makes to rise, simultaneously, conical surface annulus blank is pulled by the evagination step of block upper surface of rising to work top direction, is fixed by conical surface annulus blank from two dimensions.
Obviously, the Advantageous Effects of this utility model helical disk gear rolling clamp for machining is firmly to be fixed on the work top of lathe by conical surface annulus blank, and, easy to loading and unloading.
