Technical field
The utility model relates to a kind of workpiece overall clamping rotational processing apparatus, especially a kind of more than one piece turns round class equal part
It indexes workpieces processing overall clamping and rotates clamp for machining.
Background technique
In machining, often there is revolution class equation graduation workpieces processing that clamping is needed to process, revolution class equation graduation adds
Work workpiece refer to the first knife of workpiece after processing is completed, workpiece need to successively rotate angle carry out the second knife, third knife ... N
Knife processing, and following process is identical as the first knife, the equal part that the angle rotated every time is 360 °/N is processed.
For once carrying out the clamping of the steering processing of more than one piece revolution class equation graduation processing part, problem to be solved
Include:
(1) in order to maximally utilize equipment, to improve equipment efficiency of usage, the revolution class for carrying out corner processing is produced
Product, first is that needing the Distance Shortened between product, second is that guaranteeing the consistency and rapidity of corner；Reduce every workpiece list to the greatest extent
Solely carry out feeding, corner, positioning time；
(2) in order to improve the production efficiency, labor intensity is reduced, once multiple rows of should put more multi-work piece, and realize more than one piece workpiece
Clamp, the machining of more than one piece product completed during one-time continuous feed, reduce to the greatest extent every clamping workpiece, feeding it is cumbersome
Operation；
(3) operation ease, safety improve labor intensity etc..
At present in the revolution class workpiece product of batch production, single-piece folder is generally carried out using common chuck or oild chuck
Tightly, or using multiple groups hydraulic/pneumatic rotation-indexing table；
Be with the deficiency that common chuck or oild chuck carry out single-piece clamping: every product requires charge-press from both sides
The movement of tightly-processing-feeding (circulation), repeating not rising in value, it is more to act, and device efficiency is low, large labor intensity, although equipment component
Impulse stroke allows, can two chucks of once mounting have no idea but due to the relationship of size of chuck itself and clamping form
The processing of two pieces is completed during one-time continuous feed；
And the deficiency of multiple groups hydraulic/pneumatic rotation-indexing table then is used to be: first is that investment price is high, second is that in the depth of cut
Greatly, it impacts in biggish situation, index dial can generate strenuous vibration, and product processing quality is difficult to ensure that equipment is easily damaged.

Fill body 2, the tooling matrix is provided with N number of installation hole location arranged side by side, the installation hole location through bottom tool assembly 4, in
Portion's tool assembly 3 and top tool assembly 2, including bottom hole location, middle part hole location and top hole location, the bottom hole location, middle part hole location
It is located in bottom tool assembly, middle part tool assembly and top tool assembly with top hole location；
Positioned at outermost end installation hole location at top tool assembly 2 in and 4 top surface of bottom tool assembly have it is horizontally disposed
Steering slot I 21 and turn to slot II 41；
Swelling device is installed, the swelling device structure is identical, including pull rod 7,5 and of pull rod gear in the installation hole location
Bottom hole location, middle part hole location and top hole location are vertically installed and passed through to band gear expansion set 6, the pull rod 7, and pull rod upper end is to swing to
Wedge section 71, pull rod 7 be located at bottom hole location part be thread segment 72, it is adjacent installation hole location pull rod thread segment rotation direction phase
Instead；
The pull rod gear 5 is located at the lower end of pull rod 7 and is limited in the base apertures of bottom tool assembly 4 by middle part tool assembly 3
In position, 5 inner hole of pull rod gear is cooperated by the thread segment 72 of internal screw thread and 7 lower end of pull rod, the external gear of pull rod gear 5 with it is adjacent
Pull rod gear intermeshing in hole location is installed, outermost end is installed the pull rod gear 5 in hole location and is located at and turns in slot II 41
Swelling handle 9 connects；
It is described with 6 sets of the gear expansion set middle and upper parts in pull rod 7, and be limited in top hole location and middle part hole location；It is described
It include expansion set 61 and the expansion set gear 62 for being connected to expansion set lower part with gear expansion set 6, expansion set 61 is located on top hole location and pull rod
The wedge section 71 swung at end stretches out top tool assembly with merging, and expansion set 61 packs into workpiece lumen when use, and expansion set gear 62 limits
In the hole location of middle part, the expansion set gear in adjacent installation hole location is intermeshed, and outermost end installs the band gear expansion set 6 in hole location
It is connect with the steering tiller 8 being located in steering slot I 21；

On the contrary, but not influencing work pieces process (when the same angle of workpiece positive and negative rotation, the position of processing is identical).
Workpiece entirety swelling principle:
Swelling handle 9 is rotated, the pull rod gear 5 of outermost end is driven to rotate, since pull rod gear 5 and pull rod 7 are threadedly engaged,
And 5 axial restraint of pull rod gear (being limited in the bottom hole location of bottom tool assembly 4), pull rod 7 can be according to pull rod gear 5 at this time
Rotation direction move up and down, the wedge section of 7 upper end of pull rod will be with 6 swelling of gear expansion set, so that workpiece is swollen when moving down
Tightly.
When the pull rod gear 5 of outermost end rotates, the pull rod gear 5 in N number of installation hole location rotates simultaneously, adjacent pull rod tooth
5 rotation directions are taken turns conversely, because the screw thread of adjacent pull rod 7 is on the contrary, the direction phase that the pull rod in the N number of installation hole location of event moves up and down
Together, or simultaneously rise or simultaneously decline, realize more than one piece part overall clamping and release.
