Description

Thin Elastic annulus scapus part both ends of the surface clamp for machining

Technical field

The utility model belongs to the machining equipment field, relates to a kind of Thin Elastic annulus scapus part both ends of the surface clamp for machining, relates in particular to the anchor clamps of the both ends of the surface processing of the collapsible dist collar in a kind of main gearbox assembly of automobile drive axle.

Background technology

Collapsible dist collar is the strength member of the inside and outside bearing of pretension driving gear in the vehicle bridge main gearbox assembly.In its design length overall, the both ends of the surface depth of parallelism and roughness are all had relatively high expectations.

Because the shape of such part is drawing, and needs through both ends of the surface high-frequency quenching or integral quenching, so the size distortion of endoporus is relatively large.Traditional processing method generally is to adopt the grinding both ends of the surface, and need repair file both ends of the surface inner hole outer circularity burr, and cost is relatively large.Use turning to add man-hour, as adopt general spring chuck, tend to because of elastic failure produces the processing slip, the shake quality can't guarantee; Adopt Morse's taper as chuck body, by disassembling the chuck on the lathe, the Morse's taper of chuck body is injected the Morse's taper hole of machine tool chief axis, then with pull bar and nut, cushion cover by lathe end compressing fixture body, its effect can reach designing requirement, not only increased material and cost of manufacture but chuck body is made Morse's taper, and in use dismounting is very inconvenient, it is also poor to process other part universality.

Summary of the invention

The purpose of this utility model is to provide a kind of Thin Elastic annulus scapus part both ends of the surface clamp for machining, and the anchor clamps of the both ends of the surface processing of the collapsible dist collar in a kind of main gearbox assembly of automobile drive axle are provided especially.

The utility model is achieved in that it comprises chuck body, the sheet that rises, tapering top cover and nut, chuck body be divided into the positioning fixture head that connects with machine tool chief axis, with the corresponding transition body body body of interior lathe tool, axle journal, clamping station body body body and the bolt head corresponding with the processing parts endoporus, clamp station body body body and connect the sheet that rises, tapering top cover, nut successively, when processing parts is installed, be provided with processing stations between the both ends of the surface of transition body body body, axle journal, rise sheet and tapering top cover and processing parts.

Rise sheet radially symmetry division become more than two, rise sheet by elastic rubber band with clamp station body body body and be connected.

The male cone (strobilus masculinus) of tapering top cover and the corresponding connection of inner conical surface of the sheet that rises are provided with auxiliary cushion block between tapering top cover and the nut.

During the utility model processing parts, part is installed in the axle journal corresponding with the processing parts endoporus and clamps on one's body the station body body, clamp station body body body and connect the sheet that rises, the sheet that rises is keeping a little elasticity to adapt to the processing parts endoporus of heat place back distortion, has guaranteed preferably that again the tapering top is enclosed within the coaxial stabilization that supports with the sheet that rises in drive oing boldly.Convenient mounting and clamping is reliable, can satisfy the turning simultaneously of processing parts both ends of the surface, to the specification requirement of the depth of parallelism, length overall, roughness and removal both ends of the surface inner hole outer circularity overlap, burr.

The specific embodiment

Embodiment 1: with the part collapsible dist collar part in the main gearbox assembly of NHR vehicle drive axle assembly is example, processes its both ends of the surface.

It comprises chuck body 1, the sheet 2 that rises, tapering top cover 4 and nut 6, chuck body 1 be divided into the positioning fixture head that connects with machine tool chief axis, with the corresponding transition body body body of interior lathe tool, axle journal, clamping station body body body and the bolt head corresponding with the processing parts endoporus, clamp station body body body and connect the sheet 2 that rises, tapering top cover 4, nut 6 successively, when processing parts is installed, processing stations between the both ends of the surface of transition body body body, axle journal, rise sheet 2 and tapering top cover 4 and processing parts is 2-3mm, and promptly both ends of the surface require to vacate 2-3mm.

Rise sheet 2 radially symmetry division become more than three, the sheet 2 of rising is connected with clamping station body body body by elastic rubber band 3.

The male cone (strobilus masculinus) of tapering top cover 4 and the corresponding connection of inner conical surface of the sheet 2 that rises are provided with auxiliary cushion block 5 between tapering top cover 4 and the nut 6.

Chuck body 1 can adopt common used material 45# steel, heat treatment only needs modified getting final product, and the cylindrical and the bolt head centre bore of the clamping station body body body of the axle journal cylindrical corresponding with collapsible dist collar 7 endoporus, the positioning fixture head cylindrical that is connected with scroll chuck, connection tapering top cover 4 are coaxial; Sheet 2 internal taper holes that rise are coaxial with the cylindrical or the conical surface that clamp station body body body, and vertical with end face, the also available 45# steel of sheet 2 materials and of rising through the surfaces externally and internally Quenching Treatment, hardness is slightly high, the outside conical surface of tapering top cover 4 is coaxial with endoporus, modified the getting final product of the also available 45# steel of material.

Be clamped on the lathe scroll chuck chuck body 1 positioning fixture head also coaxial with it, processing parts collapsible dist collar 7 is installed on the axle journal of chuck body 1, nut 6 by head is tightened, auxiliary cushion block 5 transmits pressure, tapering top cover 4 is drive on boldly, cause the sheet 2 expansion stretching collapsible dist collars 7 that rise, hold out against the bolt head centre bore of chuck body 1 then with the tailstock rolling center.The running lathe, by adjusting two cutters turning simultaneously both ends of the surface of distance on the knife rest in advance, swivelling tool-holder adopts the overlap, the burr that are contained in other two the cutter inner hole outer circularities of falling both ends of the surface on the knife rest both can then.
