Technical field
The present invention relates to tyre die processing equipment technical field, more particularly to a kind of numerical control tyre mould Special three-jaw
The automatic portioning device of chuck.
Background technology
At present, the clamping of the Special Automatic drilling machine of numerical control tyre mould typically uses common two sides clamping device, passes through
Handle, which shakes, clamps workpiece, but this clamping mode is often accurate in longitudinal direction, but is laterally often difficult to control and clamps, during drilling
It is easy to that the phenomenon slid along two clamping faces occurs so that boring surface is not parallel, machining accuracy reduction is in turn resulted in, to production
Processing is made troubles, and not only influences machining accuracy, and production efficiency is relatively low.Chinese patent literature CN203091789U is disclosed
A kind of Special automatic drilling portion divider for numerical control tyre mould three-claw interlocking chuck, it includes the work on automatic drilling machine
Platform, disk body of chuck is set on the workbench, is provided with the disk body and corresponds to disk body of chuck in what equilateral triangle was set
Three claws at center, each driving claw that is equipped between claw and disk body of chuck make card along disk body of chuck radius
Tight and relaxing exercise drive mechanism.
Tire-mold is fixed using the fixed form of scroll chuck in the patent document, folder is shaken compared to traditional handle
Tightly, precision slightly raises.But because scroll chuck is during screens, can only a screens, and tire-mold is typically by gold
Category is made, and weight is larger, and scroll chuck is difficult that tire-mold is adjusted into accurate by the expansionary force of itself during screens
Position, the Product Precision so processed, which is thrown away, can not reach requirement, and defect rate is higher.
The content of the invention
Exist therefore, the technical problem to be solved in the present invention is the automatic portioning device for overcoming existing tire-mold special
Above-mentioned deficiency, and then provide and a kind of there is repeatedly adjustment, clamping function, and the number that can be accurately measured to positioning precision
Control the automatic portioning device of tire-mold Special three-jaw chuck.
To achieve the above object, the present invention uses following technical scheme：
A kind of automatic portioning device of numerical control tyre mould Special three-jaw chuck, it includes workbench, set on the workbench
Scroll chuck is equipped with, the scroll chuck includes disk body and radially clamping or three claws loosened, three claw edges
Circumferentially-spaced 120 degree of settings, the claw is driven radially movable by drive mechanism；Use is provided with above the scroll chuck
In the processing head processed to tire-mold to be processed, the processing head is fixed on the workbench by support, the processing
The downwardly directed tire-mold to be processed of head erect；It is provided with the workbench for supporting the tire-mold to be processed
Jacking apparatus, the jacking apparatus is located at outside the floor projection of the scroll chuck；Set on the table top of the workbench
There are four correlation type photoelectric sensors, the detection light of four correlation type photoelectric sensors encloses the hough transform of closing
Space, the ray height of the correlation type photoelectric sensor are located at the interposition of the thickness direction of the tire-mold to be processed
Put, the center in the hough transform space is on the axis of the scroll chuck, the floor projection of the tire-mold to be processed
In the hough transform space.
Preferably, a pole vertically stretched is respectively arranged with four angles in the hough transform space, each
The upper end of the pole is provided with a photophore and a light receiving device, described luminous on the same pole
Device and the circumferentially-spaced 90 degree of settings of the light receiving device.
Preferably, the lower end of the pole is provided with sliding block, and the sliding block is arranged in the guide groove of line slideway, described
The bearing of trend of line slideway is consistent with the diagonal in the hough transform space.
