Between the external face of thimble have sleeve, the sleeve plays positioning action to second bearing and 3rd bearing.Wherein, clutch shaft bearing is
Thrust ball bearing, second bearing and 3rd bearing are ball bearing.
Further, the taper shank front end face is provided with secondary spring at baffle plate, and the support that auxiliary is played to baffle plate is made
With.
Further, air-vent is provided with the housing, the sealing state of enclosure interior can be broken, be easy to baffle plate, thimble
The action of body etc..
Further, the housing upper is provided with machine oil injection cup near the position of bearing, convenient certain to being injected in housing
The machine oil of amount, lubrication is played to bearing, extends the service life of bearing.
Further, the lower housing portion is provided with oil overflow hole, and thus the machine oil after using long can discharge.
Further, packing is additionally provided with the adjusting nut outside the cone centre cylindrical section, plays sealing function, prevented
Thus machine oil flow out.
Further, the taper shank is Morse taper shank.
Further, there is the cavity connected with spring housing in the taper shank, taper shank rear end is provided with plug.
The beneficial effects of the utility model are：Using the elasticity of spring, baffle plate right-hand side assembly can forward be ejected or returned
Contracting, makes cone centre to carry out axial stretching, the automatic compensation workpiece deformation for causing of expanding with heat and contract with cold in itself, with workpiece center hole
All the time coordinate, it is to avoid vibration line occur, it is ensured that workpiece processing quality.Taper shank inside hollow can be set, and can back out plug, from
Hollow space inserts stock and baffle plate right-hand side assembly is ejected from enclosure interior.
