Face is provided with the tensioning contact of corresponding through hole, and the cavity bottom is provided with centering cone tank, and the mandrel clamping device includes mandrel
Tail end fixed mechanism, located at mandrel front end and the centration axis concentric with mandrel, the centration axis front end is provided with and centering cone tank
The centering of cooperation is raised, and the centration axis is interference fitted with elastic metallic cylinder.
The preferred of such scheme, the elastic metallic cylinder are provided with laterally in cavity front end as the utility model
Chamfering.
As the utility model to the preferred of such scheme, the mandrel tail end fixed mechanism is machine tool mechanical chuck.
As the utility model to the preferred of such scheme, the tensioning contact is rubber contact.
As the utility model to the preferred of such scheme, the centration axis is by linear actuator drives edge its axis side
To linear motion.
The beneficial effects of the utility model are：This kind of gear milling fixer for machining, in use, by gear
It is assemblied in after being fixed in mandrel, existing gap between gear shaft holes and mandrel, is compensated after being inserted into cavity because of centration axis,
The through hole of tensioning contact protrusion mandrel during this on the outside of elastic metallic cylinder, contacts with gear shaft holes inwall, disappears
Except the gap between mandrel and axis hole, so as to avoid the problem of positioning precision during Gear Processing is not high；Simultaneously as
Cavity bottom is provided with centering cone tank, and centration axis front end is provided with the centering projection coordinated, and the two combines and further increases tooth
Take turns the precision in process；And this kind of structure can be advantageous to improve assembling effect in the assembling of gear and mandrel with retention gap
Rate.In addition, the utility model also has simple in construction, easily operated handling characteristics.
