Description
Technical Field
The utility model relates to a turn-milling equipment technical field especially relates to a milling cutter chuck device with adjustable diameter.
Background
A milling cutter is a rotating tool with one or more cutter teeth for milling. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. The milling cutter is mainly used for processing planes, steps, grooves, formed surfaces, cut-off workpieces and the like on a milling machine. The milling cutter used in the machining center mostly adopts a spring jacket clamping mode and is in a cantilever shape when in use. During the milling process, it may sometimes happen that the milling cutter is gradually extended from the tool holder so that it is completely lost and the workpiece is rejected, due to the fact that the clamping force is not applied, which is generally caused by the presence of an oil film between the inner bore of the tool holder and the outer diameter of the milling cutter shank.
The end mill is used for processing the key slot on the milling machine, and the condition that the size of the end mill is inconsistent with that of the milling slot is often met, so that the production efficiency is low, and the processing quality cannot be guaranteed.

In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a milling cutter chuck device with adjustable diameter, includes main holder, vice holder and locking thread bush, the one end of main holder is equipped with the external screw thread, and is equipped with ann slot in the main holder, vice holder sets up the one end of keeping away from the external screw thread on main holder, and is equipped with logical groove in the vice holder, be equipped with in the locking thread bush with main holder on external screw thread assorted internal thread, and the one end of locking thread bush is equipped with fixed buckle.
Preferably, an eccentric sleeve is arranged in the main clamping seat and matched with the insertion groove.
Preferably, a plurality of open slots are arranged on the main clamping seat, and the open slots are circumferentially and uniformly distributed.
Preferably, the auxiliary clamping seat is provided with an adjusting rib sleeve, and the adjusting rib sleeve is provided with a plurality of pin grooves.
Preferably, the fixing buckle ring is provided with a through hole.
Preferably, one end of the auxiliary clamping seat, which is far away from the main clamping seat, is provided with a connecting thread.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the eccentric sleeve can make milling cutter centre gripping more firm, and the open slot provides certain range of variation to can carry out the self-regulation according to milling cutter's size.
2. The bolt slot cooperates with the bolt in the holder, can make the angle modulation that carries on that main holder, vice holder can be convenient.
Drawings
Fig. 1 is a schematic front sectional view of a milling cutter chuck device with an adjustable diameter according to the present invention;
fig. 2 is a schematic front view of a milling cutter chuck device with an adjustable diameter according to the present invention;
