The present invention solves its technical problem and takes following technical scheme to realize:
The automatic locating center device of a kind of Hub fixture, comprise chuck, locating piece, location hook, limit sliding chutes and limited post, upper end, chuck periphery spaced radial is fixed with multiple locating piece, chuck lower end outside locating piece is all hinged with a location hook, it is characterized in that: on chuck, radial equipartition is provided with many groups and automatically asks heart assembly, this asks heart group to comprise fairlead automatically, main shaft pull bar, pull-rod spring, guide runner, gathering sill, positioning sliding block and locating convex block, axially a fairlead is fixed with at chuck hub, with axially oriented, a main shaft pull bar is installed in this fairlead, this main shaft pull bar bottom is provided with pull-rod spring, main shaft pull bar upper end is fixed with a guide runner tilted to external diameter by center, this guide runner slides and is inlaid in a radial gathering sill arranged, gathering sill outer radial is fixed with a positioning sliding block, this positioning sliding block radially-directed moves, this positioning sliding block upper end is shaped with locating convex block.
And be shaped with limit sliding chutes in the middle part of described location hook, this limit sliding chutes and the limited post be packed on chuck are slidably matched.
A kind of Hub fixture asks heart method automatically, it is characterized in that: step is as follows:
Wheel hub to be processed is placed on chuck by a;
B tentatively adjusts hub positions, the card outer rim lower end of multiple locating piece common support wheel hubs that upper end, chuck periphery radial direction is arranged;
C lock in place hook, drives location hook to the rotation of chuck axial direction, and the gib head of location hook pins in the card outer rim of wheel hub, the axial location of stationary hub;
D automatic capturing, automatically ask the main shaft pull bar under tension of core structure to move, main shaft pull rod shaft drives to mobile the guide runner be obliquely installed, and this guide runner drives gathering sill to radially slide, guide runner drives positioning sliding block to move radially, thus the radial position of accurate adjustment wheel hub to be processed;
E completes location.
And radial equipartition arranges many groups and automatically asks concentric mechanism in the card of described chuck, automatically ask concentric mechanism action simultaneously for these many groups.
And described concentric mechanism of automatically asking is 3 to 6 groups.
Advantage of the present invention and good effect are:
The present invention determines the center of circle within the specific limits automatically by making radial location block, makes blank automatic capturing, improves positioning precision, and what minimizing was not just producing because being installed scraps, and improves blank radial location precision.
