Abstract

The invention discloses a clamp for turning an eccentric oil groove in a spherical surface of a planet gear. The clamp is composed of a middle joint, bolts, a core shaft, a die holder, an inner sleeve, a screw and a pad. A plane where the middle joint is combined with a machine tool serves as a plane benchmark, and an axial positioning hole is arranged in the middle of the other inclined plane. A left shaft end of the core shaft is inserted in the axial positioning hole of the middle joint, and the core shaft and the middle joint are connected through the bolts. A left end surface of the die holder and an inner hole of the die holder match with the core shaft, the die holder is connected with the core shaft through the bolts, and an inner toothed die matching with taper teeth of a workpiece is arranged at an outward opening. The inner sleeve is mounted at a free end of the core shaft, the inner sleeve and the core shaft are axially locked through the screw, and the inner sleeve is inserted in an inner hole of the workpiece and axially limited through an external taper tooth platform. According to the clamp, the inclined plane is arranged according to eccentricity, and above all, the workpiece is meshed with the die holder through teeth, so that the rotation freedom degree on a Y axis is eliminated, the turning resistance is greatly improved through the structure, and the re-mounting accuracy during reworking of workpieces can be guaranteed.

Description

The eccentric oil groove anchor clamps of Vehicle Processing planetary gear sphere
Technical field
The present invention relates to a kind of turning attachment, specifically, the present invention relates to a kind of positioning fixture for the eccentric oil groove of turning bevel planet gear sphere.
Background technology
The bevel planet gear back side in the automobile differential is spherical structure, and this sphere contacts cooperation with differential casing, and along with the increasing of transmitting moment of torsion, sphere bears also corresponding increase of frictional force.In order to prevent that sphere from producing excessive temperature, the industry generally arranges eccentric oil groove at sphere, can effectively solve the planetary gear sphere by the raising lubricating condition and fall heat problem.Owing to the bevel planet gear profile is special, must could realize eccentric oil groove turning processing by anchor clamps, the industry generally adopts radial misalignments that workpiece is installed, and the clamp structure of prior art is simple, making is easy, can realize the processing of the eccentric oil groove of sphere.But, the maximum deficiency of prior art be in the structure without limits Y-axis to rotary freedom, cutting resistance can be not enough in actual the use, workpiece easily takes place sway and random groove problem takes place.In addition, the installation that can not accurately reset after workpiece unloads, the task difficulty of doing over again is too big, and these realistic problems have restricted production efficiency and the quality of the eccentric oil groove of industry bevel planet gear sphere.
Summary of the invention
The present invention is primarily aimed at the deficiencies in the prior art, proposes a kind of simple in structure, easy to loading and unloading, accurate positioning, the eccentric oil groove anchor clamps of the workpiece Vehicle Processing planetary gear sphere that (Y-axis to) rotary freedom is limit on locating shaft.
The present invention is achieved through the following technical solutions technical goal.
The eccentric oil groove anchor clamps of Vehicle Processing planetary gear sphere, it is made of jointly center tap, bolt, mandrel, die holder, interior cover, screw and pad.Its improvements are: described center tap is basic connector, and both ends of the surface are not parallel, and the one side of being combined with lathe is datum plane, and another inclined-plane is provided with the axial location hole between two parties.Described mandrel is shoulder axle construction, and left axle head inserts in the axial location hole, center tap inclined-plane, and both connect by bolt, and right axle head is cantilever-shaped.Described die holder is the pipe box member, and left side and endoporus thereof cooperate the location and connect with bolt with mandrel, outwardly uncovered being provided with by the supporting internal tooth mould of the awl tooth of workpiece.Cover is installed in the mandrel free end in described, and both make axial locking with screw, and interior cover plug is made axial limiting in the workpiece endoporus and by the outer cone boss.
In the said structure, angle is determined by the offset of eccentric oil groove between the inclined-plane of center tap and the plane.
The present invention compared with prior art has following good effect:
1, tooth mould accurate positioning repeats the installation accuracy height;
2, Y-axis to rotary freedom limit, random groove accident can not take place during the eccentric oil groove of turning.
Description of drawings
Fig. 1 is structural profile schematic diagram of the present invention.
Fig. 2 is the schematic diagram of showing eccentric oil groove on the workpiece end face.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
The eccentric oil groove anchor clamps of Vehicle Processing planetary gear sphere shown in Figure 1, it is by center tap 1, bolt 2, mandrel 3, die holder 4, interior cover 5, screw 6 and fill up 7 and form jointly.Center tap 1 is basic connector, and both ends of the surface are not parallel, and the one side of being combined with lathe is datum plane, and the other end of opposite planar benchmark is the inclined-plane, and the inclined-plane is provided with the axial location hole between two parties.The oblique angle of the inclined-plane opposite planar benchmark of center tap 1 is determined by the offset of eccentric oil groove to be processed, the present embodiment workpiece is the supporting bevel planet gear of DYMOS automobile gearbox, eccentric oil groove on the sphere as shown in Figure 2, eccentric amount e=4.5mm, inclined-plane opposite planar benchmark angle α=3 of center tap 1 as calculated 017 ' just can realize the turning processing of eccentric oil groove.Described mandrel 3 is shoulder axle construction, and left axle head inserts in the axial location hole, center tap 1 inclined-plane, constitutes mandrel 3 location and installation, and mandrel 3 is connected on the center tap 1 by bolt 2, and mandrel 3 right axle heads are the suspended wall shape.Described die holder 4 is the pipe box member, is the special purpose parts that the present invention designs according to workpiece 8 positioning and clamping.Die holder 4 left sides and endoporus thereof cooperate the location with mandrel 3, connect with bolt 2 between the two, outwardly uncovered being provided with by the supporting internal tooth mould of workpiece 8 awl teeth.Cover 5 is installed in mandrel 3 free ends in described, and both make axial locking with screw 6, and interior cover 5 plugs are made axial limiting in workpiece 8 endoporus and by the outer cone boss.
During practical application of the present invention, workpiece 8 is set on mandrel 3 cantilever ends, the flank of tooth of workpiece 8 faces die holder 4, and sphere outwardly.Then interior cover 5 is set to and also fills on the mandrel 3 in workpiece 8 endoporus, with cover 5 in screw 6 axial lockings.In above-mentioned location and installation condition, workpiece 8 is reliably installed, is accurately located, and particularly meshes by tooth between workpiece 8 and the die holder 4, has eliminated the rotary freedom on the Y-axis.This structure also can guarantee to reinstall when workpiece is done over again precision except the ability that improves cutting resistance greatly.
