Abstract
The utility model discloses spiral bevel gear mills with clamping apparatus, including the bottom plate, core and guide post rise, the pore area is tapered in ring shape bottom plate and the tip cylindrically rises that the core is coaxial to be fixed on the machine tool table face, and the coaxial setting of guide post activity of the outer bobbin tape back taper degree of tip is at the core center of rising, the other end of guide post with lock cylinderpiston and be connected, and, the tapering of core tip hole and the back taper degree phase -match of guide post tip excircle rise. The utility model discloses spiral bevel gear mills with clamping apparatus's useful technological effect be can be firm fix conical surface ring blank on the table surface of lathe to, loading and unloading are convenient.
Description
Technical field
This utility model relates to spiral bevel gear Milling Machining technology, is related specifically to a kind of spiral bevel 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 spiral bevel gear.During manufacturing spiral bevel gear, profile to be produced shows conical surface annulus with spiral bevel 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 spiral bevel gear rolling clamp for machining.
This utility model spiral bevel gear rolling clamp for machining, including base plate, rise core and lead；In annular base plate and end, the cylinder of the pore area tapering core that rises coaxially is fixed on platen face, outside end, the lead activity of round belt back draught is co-axially located at Zhang Xin center, the other end of lead is connected with locking cylinder piston, further, the tapering of core end endoporus that rises described in matches with the back draught of lead end cylindrical.
Further, described in the rise side, end of core ribbon tapering be provided with contraction mouth, and, described contraction mouth is the most uniform.
Further, the contraction mouth quantity of core of rising described in is three or more than three.
The Advantageous Effects of this utility model spiral bevel 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 spiral bevel gear；
Accompanying drawing 2 is the schematic three dimensional views of this utility model spiral bevel gear rolling clamp for machining clamping blank；
Accompanying drawing 3 is the cross-sectional schematic of this utility model spiral bevel gear rolling clamp for machining clamping blank.
With specific embodiment, this utility model spiral bevel 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 spiral bevel gear, as seen from the figure, during manufacturing spiral bevel gear, profile to be produced shows conical surface annulus with spiral bevel 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 spiral bevel gear rolling clamp for machining clamping blank, and accompanying drawing 3 is the cross-sectional schematic of this utility model spiral bevel gear rolling clamp for machining clamping blank, in figure, 1 is base plate, 2 is the core that rises, and 3 is lead, and A is conical surface annulus blank.As seen from the figure, this utility model spiral bevel gear rolling clamp for machining, including base plate 1, rise core 2 and lead 3；In annular base plate 1 and end, the cylinder of the pore area tapering core 2 that rises coaxially is fixed on platen face, outside end, lead 3 activity of round belt back draught is co-axially located at core 2 center of rising, the other end of lead 3 is connected with locking cylinder piston, further, the tapering of core 2 end endoporus that rises described in matches with the back draught of lead 3 end cylindrical.When specifically used, conical surface annulus blank is placed on outside the core that rises, open cylinder, lead moves to the core inner that rises under the drive of cylinder piston, owing to the tapering of the core end endoporus that rises matches with the back draught of lead end cylindrical, the entrance of the lead core that makes to rise expands laterally so that conical surface annulus blank is risen core clamping.
Obviously, for ensureing to rise the expansion effect of core, described in the rise side, end of core ribbon tapering be provided with contraction mouth, and, described contraction mouth is the most uniform.Further, the contraction mouth quantity of core of rising described in is more than three.
Obviously, the Advantageous Effects of this utility model spiral bevel 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.
