Detailed description of the invention
By making, architectural feature of the present utility model and effect of being reached are had a better understanding and awareness, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
A kind of cylindrical grinder self-compensating floating claw power chuck, including:
Housing, described housing includes the center 102 being axially arranged with central through hole 101 and the shell 103 being sheathed on outside center 102, is formed with receiving chamber between described center 102 and shell 103；The inwall of described central through hole 101 is provided with the screwed hole 104 for fixing chuck on top.By central through hole 101 be enclosed within grinding machine top on, be provided with fixing bolt by the screwed hole 104 of central through hole 101, chuck be fixed on top, chuck jaw and top relative axial position can be adjusted easily simultaneously.
Described shell 103 is provided with connection dish 105 away from the end face of floating disc 301, described connection dish 105 is provided with the groove 106 of fixing headstock driving lever, being inserted directly into for headstock driving lever, the power of card disc spins and clamping and release is provided by headstock driving lever, to existing machine tool headstock without doing any change.
This structure chuck deadweight be placed on lathe top on, headstock driving lever provides only rotary power, it is to avoid the overload operation of headstock bearing.Chuck hub set 102 be fixed on lathe top on, do not rotate, bite and top axial location can be adjusted by it.
Bearing connects unit, described bearing connects unit and is located at receiving intracavity, described bearing connects unit and includes needle roller unilateral bearing 201, intermediate bearing sleeve 202 and rolling bearing 203, described needle roller unilateral bearing 201 is sheathed on the outer ring of center 102, described intermediate bearing sleeve 202 is fixed on the outer ring of needle roller unilateral bearing 201, and described rolling bearing 203 is sheathed on intermediate bearing sleeve 202 outer ring and is connected with shell 103 inner ring；Described rolling bearing 203 is needle bearing.
Outer shroud, adapter ring rotate along with machine tool headstock adding man-hour together, and when workpiece loading and unloading, the headstock inverts, adapter ring, under needle roller unilateral bearing 201 acts on, does not rotates, and outer shroud rotates together along with headstock driving lever, outer shroud is relative with adapter ring to be inverted, and jaw is opened, and workpiece can load and unload freely.
Floating clamping mechanism unit, described floating clamping mechanism unit includes floating disc 301 and is located at the claw 302 for clamping workpiece of floating disc 301 outer face, and described floating disc 301 passes through gland 303 floating mount on shell 103 end face.Described gland 303 is sheathed on described center 102 outer ring, is connected by elastic component 304 between outer ring and the inner ring of intermediate bearing sleeve 202 of described gland 303.Described elastic component 304 is stretching spring.
It is three that described claw 302 is uniformly distributed along floating disc 301 circumference, waist-shaped hole 305 is offered on described claw 302, described claw 302 is fixed on floating disc 301 by being fed through the screw of waist-shaped hole 305, three claws 302 rotate along the screw being fixed on floating disc 301, connecting in the middle part of claw 302 and have torsionspring, described shell 103 is connected by fastening bolt is fixing with intermediate bearing sleeve 202.
Chuck is opened after putting into workpiece, and under spring force, three claws 302 contact and clamp workpiece, it is ensured that workpiece can not rotate along cutting force direction in chuck, and simultaneously under the effect of floating disc 301, workpiece radially can do a range of floating.After workpiece is risen by Double Tops pinnacle, workpiece is felt relieved, and card dribbling self compensation is floated, and provides only rotary power, workpiece is not applied radial force, it is ensured that workpiece grinding accuracy.
Described claw 302 is involute-type on the circumference at floating disc 301 center.
Creative for involute for claw line style, under meeting the oblique condition of self-locking of cam, calculate and select suitable involute parameter, the preferably line segment of OK range.Relative to heart carrier circle eccentric cam line style, there is bigger clamping force and chuck stroke, and in total travel section, there is more preferable self-locking property.
