Description
Technical field
The utility model relates to grinding machine field, specifically a kind of cylindrical grinder clamping device.
Background technology
At present, relating to axial workpiece cylindrical machining process is located by thimble, is clamped by heart carrier for bolt.Because heart carrier for bolt occupies excircle of workpiece one section of region, when workpiece one end process finishing, workpiece is reversed end for end clamping, the reprocessing other end.But a lot of pin shaft parts only has a cylindrical or has very short class's cylindrical, and axle includes through hole and screwed hole and heat-treated requires that restriction is not suitable for increasing technique body.Like this, with general heart carrier for bolt clamping work pieces, same periphery can not be made in continuous cutting process to complete processing, easily cause disalignment and diameter dimension difference, thus affect the quality of workpiece.
Utility model content
The purpose of this utility model is the cylindrical grinder clamping device providing a kind of structure simple, easy to use, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of cylindrical grinder clamping device, comprise thimble, grinding wheel spindle, housing, axle and grinding wheel unit, described thimble is fixedly located on machine tool chief axis, and machine tool chief axis is also provided with tail thimble, machine tool chief axis front portion is provided with sleeve pipe and the dead man of short thread, and dead man vertical welding is on sleeve pipe; Described grinding wheel spindle is arranged in housing by bearing, and grinding wheel spindle front end is provided with grinding wheel unit, and bearing comprises bearing skin and bearing internal layer, and bearing skin is provided with thin film restrictor, and bearing internal layer is provided with orifice restriction device; Described thin film restrictor comprises upper half shell and lower half shell, a cavity is surrounded after together with upper half shell and lower half shell are fixedly assemblied in, film is provided with between upper half shell and lower half shell, cavity in housing is divided into upper oil cavitie and lower oil cavitie by film, upper half shell and lower half shell are provided with the fuel feed hole and oil outlet that communicate with corresponding oil pocket separately, grinding wheel spindle front end is provided with height and rigidly fixes supporting construction, and housing bottom is provided with lathe mounting bracket, and grinding wheel spindle rear end is provided with motor.
Further: described thimble is fixedly connected with machine tool chief axis by Morse's taper and tailing screw flight hole.
Further: described casing pipe sleeve is located on thimble.
Compared with prior art, structure of the present utility model is simple, easy to use, adopt once simple clamping, just bearing pin class one end can be had the periphery of internal screw workpiece Continuous maching in clamped one time complete, compared with traditional lathe heart-shaped fixture, avoid secondary tune clamping and cause same outer circles and size difference, improve machining accuracy.
