Specific implementation mode
Following specific implementation mode will be further illustrated in conjunction with above-mentioned attached drawing.
Hereinafter, a variety of specific details are elaborated, in order to provide the saturating of the concept to constituting described embodiment basis
Thorough understanding.However, it will be apparent to those skilled in the art that described embodiment can be in these no specific details
In some or all situations get off practice.In other cases, well-known processing step is not specifically described.
As shown in Figs 1-4, differential carrier smart car tooling, include the terminal pad 1 being connect with lathe spindle 100 and be set to lathe
The top 2 of 110 end of mandril in main shaft 100.The end of the terminal pad 1 connects a positioning seat 3.It is set in the positioning seat 3
In pilot hole, the pilot hole is interior to be equipped with a sliding block 4.Being equipped in the positioning seat 3 pushes the sliding block 4 to be slided toward 100 end of main shaft
Dynamic multiple springs 5.The end of the positioning seat 3 is equipped with guided missile positioning seat 6；It is poor that clamping is arranged on the guided missile positioning seat 6
The guided missile 7 of 200 both ends axle shaft gear mounting hole of fast device shell, a pull rod 8 are connect across the guided missile positioning seat 6 with the sliding block 4.
The spring 5 pushes the sliding block 4 to slide so that 7 distending of the guided missile is clamped differential casing by the pull rod 8.Therefore, exist
When smart car differential carrier 200, differential carrier 200 is sleeved in guided missile 7 so that the two-semiaxle pinion mounting holes of differential carrier 200
The both ends of guided missile 7 are located in, by the mandril 110 of lathe toward 100 contract of lathe spindle, under the action of spring 5, pushes and slides
Block 4 slides in pilot hole, to drive pull rod 8 to strut guided missile 7, reaches and clamps differential carrier 200.Pass through the same bullet
7 pairs of differential carriers 200 of set play positioning and clamping, not only increase positioning accuracy, and operation is more simplified.In differential
After the completion of 200 turning of device shell, the elastic force of spring 5 is overcome by the promotion sliding block 4 of mandril 110 of lathe, to push sliding block 4 and draw
Bar 8 reaches so that guided missile 7 is shunk toward movement outside and unclamps differential carrier 200, to which shell unloads differential carrier 200
Under so that differential carrier 200 loads and unloads efficient.Reached by the elastic force of spring 5 and clamp differential carrier 200, is to pass through bullet
The compression travel of spring 5 carrys out the elastic force of adjustment spring, pulls pull rod to strut guided missile instead of conventionally employed hydraulic cylinder, due to tradition
Hydraulic cylinder accelerator rod stroke it is longer, be when the resistance of pull rod being subject to be more than or equal to hydraulic cylinder accelerator rod pulling force when just stopping,
Therefore reach and play a protective role to guided missile.
Further, the both ends of the guided missile 5 respectively on the circular conical surface and the guided missile positioning seat 6 on the pull rod 8
Circular conical surface taper fit.Therefore, when 5 pushing drawing rod 8 of spring is distracted by guided missile 7, the circular conical surface on guided missile positioning seat 6 is made
Under so that the both ends of guided missile 7 strut to reach and clamp differential carrier 200.
Further, the taper hole at 7 both ends of the guided missile is symmetrical arranged.
Further, the both ends of the guided missile 7 are equipped with clearance position 70.Differential carrier 200 is played by clearance position 70 and is kept away
Sky effect, reduces positioning surface, improves positioning accuracy；And the screen resilience of guided missile 7 can be increased.
Further, be additionally provided with avoiding hollow groove 71 in the guided missile 7, a rotation stopping screw 9 pass through the avoiding hollow groove 71 with it is described fixed
Position seat 6 connects.Guided missile 7 can effectively avoid guided missile 7 from spinning in turnery processing after clamping differential carrier 2.
Further, also removably it is cased with a positioning sleeve 60 on the guided missile positioning seat 6.In turning clamping, by fixed
The X-direction of position 60 pairs of differential carriers 200 of set plays positioning action.And positioning sleeve 60 can realize replacement, and it is different to reach satisfaction
The differential carrier 200 of model is processed.
Further, multiple stop screws 11 are threadedly coupled across the sliding block 4 with the positioning seat；The stop screw 11
The stroke for limiting the sliding block 4 is 2-3mm.
Further, the end of the pull rod 8 is additionally provided with top location hole 80.After the clamping of differential carrier 200, for turning
Stability, can be also located on top location hole 80 by the tail top of lathe.
Further, the spring 5 is Rectangular Spring.
The utility model is not limited to above-mentioned specific embodiment, and those skilled in the art visualize from above-mentioned
Hair, without performing creative labour, the various transformation made are all fallen within the scope of protection of the utility model.
