In order to overcome the above-mentioned defect that exists among the prior art, the utility model discloses enable the cutter arbor and obtain reliable support to can rotate and the irrotational according to the rotatory condition of cutter arbor, and can be reliable control cutter arbor and this cutter arbor gyration support the fit clearance between, reduce the wearing and tearing that cutter arbor and cutter arbor gyration supported relevant part, solve the cutter arbor vibrations of deep hole man-hour simultaneously, the rigidity of the cutter arbor that improves simultaneously, the defect and not enough of traditional mode have been compensatied, and then improve BTA quality scheduling problem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide one kind and enable the cutter arbor and obtain reliable support to can rotate and the irrotational according to the rotatory condition of cutter arbor, and can be reliable control cutter arbor and this cutter arbor gyration support the fit clearance between, reduce the wearing and tearing that cutter arbor and cutter arbor gyration supported relevant part, solve the cutter arbor vibrations of deep hole man-hour simultaneously, the cutter arbor gyration strutting arrangement of the rigidity of the cutter arbor that improves simultaneously.
The technical scheme of the utility model is that: the utility model provides a cutter arbor gyration strutting arrangement, its includes that supporting seat, rotation axis, tapered roller bearing, gland nut, adjusting nut, thrust ball bearing and damping support the cover, wherein the side is reverse to install respectively about supporting seat and the rotation axis tapered roller bearing, the right side of supporting seat uses respectively gland nut and gland nut are with both sides bearing pretension, be equipped with in the left side of supporting seat adjusting nut, adjusting nut is inside to be equipped with thrust ball bearing, be equipped with in the middle taper hole position of rotation axis the damping supports the cover, gland nut is equipped with on the right side of rotation axis, the last locking screw that is equipped with of gland nut.
Furthermore, a rotating check ring is installed on the fixed side of the thrust ball bearing, the check ring is installed after the rotating check ring penetrates through the thrust ball bearing and the adjusting nut, and the adjusting check ring is installed at the front end of the adjusting nut.
To sum up, the beneficial effects of the utility model are that: the utility model discloses a cutter arbor gyration strutting arrangement supports the cooperation that cover and cutter arbor and compress tightly the condition and adjust energy-conserving messenger cutter arbor and obtain reliable support according to middle damping through left side adjusting nut and right side gland nut, and can rotate and irrotational according to the rotatory condition of cutter arbor, and the cooperation clearance between reliable control cutter arbor and this cutter arbor gyration support, reduce the wearing and tearing that cutter arbor and cutter arbor gyration supported relevant part, solve the cutter arbor vibrations of deep hole man-hour simultaneously, the rigidity of the cutter arbor that improves simultaneously, the defect of traditional mode has been remedied and not enough, and then improve BTA quality scheduling problem.
The present invention will be described in more detail by way of examples.
