Technical field
The present invention relates to three pin shaft fork production technical fields of universal joint, more particularly to a kind of three pin shaft forks production is used
Angular positioner.
Background technology
The pin shaft fork of constant velocity shaft parts three is in mechanical processing process, because the particularity of workpiece lumen,
Some critical processes (such as intermediate frequency, mark, grinding) plus man-hour requirement ensure that the orientation of workpiece is consistent, and this is accomplished by adding
Ensure workpiece by an auxiliary mould by the workpiece correction in different directions to same direction, the auxiliary mould one before work
As be referred to as angular positioner.Existing angular positioner is general under rotary cylinder, clamping fixture seat, positioning fixture and auxiliary
Press mechanism is constituted, and its principle is rotary cylinder rotating localization jigs, and auxiliary press mechanism gives workpiece one downward pressure, when fixed
The direction of position fixture rotate to it is consistent with workpiece when, workpiece press-in positioning fixture positioning, then rotary cylinder drives workpiece to revolve again
Go to a fixed position, realize the positioning regulation on workpiece direction, but its have the disadvantage pneumatic needs and electrical control, into
This height, fault rate is high, restriction processing beat.
Accordingly, it would be desirable to a kind of angular positioner of Purely mechanical without electrical control.
The content of the invention
The shortcoming of prior art in view of the above, it is an object of the invention to provide a kind of angle of three pin shaft forks production
To positioner, for solve angular positioner cost in the prior art it is high, it is easy-maintaining the problem of.
In order to achieve the above objects and other related objects, the present invention provides a kind of angular positioning dress of three pin shaft forks production
