Abstract
The utility model discloses a locating turning clamp of a planetary bevel gear spherical eccentric oil groove. The locating turning clamp is composed of a middle connector, bolts, a spindle, a die base, an inner sleeve, screws and a pad. The combined face of the middle connector and a machine tool is used as a plane standard, an axial locating hole is formed in the middle of an oblique plane, the left spindle end of the spindle is inserted in the axial locating hole of the middle connector, and the left spindle end and the axial locating hole are connected through the bolts. The left end face and an inner hole of the die base are matched with the spindle and are connected with the spindle through the bolts. An inner gear die matched with a workpiece bevel gear is arranged in an outwards opening mode, the inner sleeve is arranged at the free end of the spindle, and the inner sleeve and the free end of the spindle are locked in the axial direction through the screws. The inner sleeve is arranged in a workpiece inner hole and is limited in the axial direction through an external bevel gear table. The oblique plane is arranged according to eccentricity, a workpiece is meshed with the die base through teeth, so that rotation freedom in the Y axis is eliminated, the locating turning clamp greatly improves turning resistance, and can ensure reinstallation accuracy when the workpiece is reworked.
Description
Technical field
The utility model relates to a kind of turning attachment, and specifically, the utility model relates to a kind of positioning fixture for turning bevel planet gear sphere eccentric oil groove.
Background technology
The bevel planet gear back side in automobile differential is spherical structure, and this sphere contacts cooperation with differential casing, and along with the increasing of transmitting torque, 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 on sphere, can effectively solve spherical surface of planetary gear by the raising lubricating condition and fall heat problem.Because the bevel planet gear profile is special, must could realize eccentric oil groove turning processing by fixture, 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 sphere eccentric oil groove.But the maximum deficiency of prior art is not limit the rotary freedom of Y-axis in structure, in actual the use, cutting resistance can be not enough, workpiece easily occurs and sway and random groove problem occurs.In addition, after workpiece unloads, can not install by parking position accuracy, the task difficulty of doing over again is too large, and these realistic problems have restricted production efficiency and the quality of industry bevel planet gear sphere eccentric oil groove.
The utility model content
The utility model, mainly for the deficiencies in the prior art, proposes a kind of simple in structure, easy to loading and unloading, accurate positioning, the workpiece bevel planet gear sphere eccentric oil groove that (Y-axis) rotary freedom is limit on locating shaft location turning clamp.
The utility model is achieved through the following technical solutions technical goal.
Bevel planet gear sphere eccentric oil groove location turning clamp, it consists of jointly center tap, bolt, mandrel, die holder, inner sleeve, 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 axial location hole, center tap inclined-plane, and both are bolted, and right axle head is cantilever-shaped.Described die holder is the pipe box member, and left side and endoporus thereof coordinate location and connect with bolt with mandrel, uncovered is provided with the internal tooth mould supporting by the cone tooth of workpiece outwardly.Described inner sleeve is arranged on the mandrel free end, and both make axial locking with screw, and the inner sleeve plug is made axial limiting in inner hole of workpiece and by the outer cone boss.
In said structure, the offset that between the inclined-plane of center tap and plane, angle is pressed eccentric oil groove is determined.
The utility model compared with prior art, has following good effect:
1, tooth mould accurate positioning, repeat installation accuracy high;
2, the rotary freedom of Y-axis is limit, and random groove accident can not occur during the turning eccentric oil groove.
The accompanying drawing explanation
Fig. 1 is the utility model structural profile schematic diagram.
Fig. 2 is the schematic diagram of showing eccentric oil groove on workpiece end face.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Bevel planet gear sphere eccentric oil groove shown in Fig. 1 location turning clamp, it is by center tap 1, bolt 2, mandrel 3, die holder 4, inner sleeve 5, screw 6 and pad 7 and jointly form.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 inclined-plane, and 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 sphere as shown in Figure 2, eccentric amount e=4.5mm, the inclined-plane opposite planar benchmark angle α of center tap 1=3 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 center tap 1 axial location hole, inclined-plane, forms mandrel 3 location and installation, and mandrel 3 is connected on center tap 1 by bolt 2, and the right axle head of mandrel 3 is the suspended wall shape.Described die holder 4 is the pipe box member, is the special purpose parts that the utility model designs according to workpiece 8 positioning and clamping.Die holder 4 left sides and endoporus thereof coordinate location with mandrel 3, with bolt 2, connect between the two, outwardly uncovered being provided with by the supporting internal tooth mould of workpiece 8 cone tooth.Described inner sleeve 5 is arranged on mandrel 3 free ends, and both make axial locking with screw 6, and inner sleeve 5 plugs are made axial limiting in workpiece 8 endoporus and by the outer cone boss.
During the utility model practical application, workpiece 8 is set on mandrel 3 cantilever ends, the flank of tooth of workpiece 8 faces die holder 4, and sphere outwardly.Then inner sleeve 5 be set on mandrel 3 and fill in workpiece 8 endoporus, by screw 6 axial locking inner sleeves 5.In above-mentioned location and installation condition, workpiece 8 is reliably installed, is accurately located, and particularly between workpiece 8 and die holder 4, by tooth, meshes, and has eliminated the rotary freedom on the Y-axis.This structure, except greatly improving the ability of cutting resistance, also can guarantee when workpiece is done over again to reinstall precision.
