Abstract
The invention discloses a fixture for slotting a male spline of an axle shaft gear. The fixture consists of a screw, a gasket and a tooth die, wherein the tooth die is arranged on a machine tool working table in a positioning manner, and the screw vertically penetrates the inner bore of the tooth die so as to be connected with a machine tool pull rod; the gasket is an opening gasket, and the gasket is matched with the screw to form a quick assembly and disassembly structure; a concave die cavity of which the conical tooth faces upwards is formed in the tooth die, and the conical tooth parameter of the die cavity is equal to that of a workpiece. According to the fixture disclosed by the invention, the workpiece is positioned by the tooth die, and a bolt is located in the inner bore of the workpiece and is used for axial locking, so that the outer wall of the workpiece has no barriers, and the male spline of the workpiece can be conveniently slotted; the aims that the slotting quality is good, and the production efficiency is high are achieved.
Description
Technical field
The present invention relates to a kind of machining fixture, specifically, the present invention relates to a kind of fixture for shaft member external splines shaping, particularly a kind of axle shaft gear external splines slotting fixture.
Background technology
The axle shaft gear of commercial car differential mechanism is a kind of gear shaft component, and namely an axle head is bevel gear, and another axle head outer wall is provided with external splines.This class A of geometric unitA is under existing technological equipment condition, and first-selected manufacturing process is first finish forge bevel gear, and then processes the external splines of the other end with Bevel Slotting Technology.Owing to limiting and Bevel Slotting Technology by axle shaft gear structure, the special shaping fixture that the industry makes generally adopts plug and expansion set fit structure, then the method being aided with bevel gear small end face axial limiting and compression realizes location processing.This kind location and installation way easy, reliable, external splines shaping can be realized.Its deficiency is that the external splines precision processed is not high, quality is unstable, tracing it to its cause is that expansion set positioning precision is poor, adds axial location and does not eliminate beating of bevel gear small end, external splines and the bevel gear of processing before and the interior axially bored line generation deviation of the aft-loaded airfoil made.
Summary of the invention
The present invention, mainly for the deficiency of prior art products, proposes a kind of axle shaft gear external splines slotting fixture, and this clamp structure is simple, accurate positioning, reliable clamping, dismounting are convenient.
The present invention is achieved through the following technical solutions technical goal.
Axle shaft gear external splines slotting fixture, it is made up of screw rod, pad and tooth mould.Described tooth mould location and installation is on platen, and screw rod vertically runs through tooth mould endoporus and is connected with lathe pull bar.Described pad is open washer, and pad coordinates with screw rod and forms workpiece quick dispatch structure.Its improvements are: described tooth mould is provided with cone tooth female mould cavities upward, and the cone tooth parameter in die cavity is identical with workpiece.
In said structure, the maximum outer wall dimension of screw tip is less than inner hole of workpiece, and pad maximum outside diameter is less than the root circle 5 ~ 8mm of workpiece external splines.
The present invention compared with prior art, has following good effect:
1, workpiece is located by tooth mould, and it is axially, the radial and free degree that pivots limited, and accomplish that design basis overlaps with positioning datum, thus location reliably, accurate;
2, workpiece is located by tooth mould, and the foozle of workpiece cone tooth small end face does not affect external splines machining accuracy;
3, screw rod is arranged in inner hole of workpiece and makes axial locking, is convenient to shaping workpiece external splines, is conducive to enhancing productivity.
Accompanying drawing explanation
Fig. 1 is structural profile schematic diagram of the present invention.
Fig. 2 is workpiece schematic perspective view.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
Axle shaft gear external splines slotting fixture shown in Fig. 1, it is made up of screw rod 1, pad 2, tooth mould 3.Described tooth mould 3 belongs to a kind of tubular element, and perpendicular tooth mould 3 bottom face put is provided with evagination shoulder and coordinates with the shrinkage pool on platen and locate, and the tooth mould 3 of location and platen are connected to integrally.Tooth mould 3 one side is upward provided with the female mould cavities of cone tooth, and the cone tooth parameter in die cavity is identical with workpiece 4.Described screw rod 1 is the securing member for axial locking workpiece 4, and it vertically runs through connecting machine tool pull bar after tooth mould 3 endoporus.Described pad 2 is a kind of open washers, is form workpiece 4 quick dispatch structure by the object that pad 2 coordinates with screw rod 1.The present embodiment axle shaft gear is the auxiliary equipment of 9 commercial car differential mechanisms, this part endoporus Φ 28mm, external splines root circle Φ 36mm.The fixture of this kind of shrink-fit structure is convenient to workpiece 4 and is engaged with tooth mould 3 through screw rod 1 down with increment, workpiece 4 is located by tooth mould 3, its free degree that is axial, radial and that pivot all is limited, and accomplishes that design basis overlaps with positioning datum, reaches the expection of accurately location.This kind of location structure makes cone tooth small end face suspend not Contact Tooth mould 3, and its foozle does not affect positioning precision.Workpiece 4 inserts pad 2 on workpiece 4 top and screw rod 1 gap after locating, and starts lathe pull bar linkage screw 1 axial locking workpiece 4.Screw rod 1 in the present invention is arranged in workpiece 4 endoporus and makes axial locking, and because workpiece 4 outer wall is without any barrier, therefore be convenient to the external splines that shaping workpiece does 4, shaping quality is good, and production efficiency is high.After external splines slotting is shaping, screw rod 1 moves upward under the effect of lathe pull bar, takes out pad 2, and the axis along screw rod 1 takes out the workpiece 4 of completion, and the workpiece 4 changing the outfit to be processed is done new one and taken turns location and installation, locking and shaping.
