Grinding machine upper fixed disk core-regulating mechanism.
In order to solve the above technical problems, the solution that the utility model uses is:
A kind of accurate twin grinder upper fixed disk core-regulating mechanism, including upper fixed disk, cylinder and cross-garnet butt are provided；
Cross-garnet butt is set to upper fixed disk upper surface by upper disk support rod, and cross-garnet butt center is solid by aligning inner ring pin shaft
Equipped with bearing block；Bearing is installed in bearing block, connecting shaft is installed in bearing；Connecting shaft top is connected by weighing sensor
Common commercial product can be used in upper disk fixed link, weighing sensor.The piston rod of connection cylinder at the top of upper disk fixed link.
As an improvement cross-garnet butt includes the core-regulating mechanism inner ring being mutually arranged and core-regulating mechanism outer ring；Aligner
Bearing block is installed in structure inner ring, one group of bearing is equipped between core-regulating mechanism inner ring and core-regulating mechanism outer ring, and adjust bearing with gland
Gap.
As an improvement bearing block and aligning inner ring pin shaft pass through pin connection.
As an improvement upper disk fixed link is equipped with round nut used for positioning, copper gasket for positioning, limiting,
Holding screw and clump weight.
As an improvement cylinder end is equipped with air cylinder fixed plate.
As an improvement connecting shaft is equipped with round nut used for positioning, copper gasket and tightening for positioning, limiting
Screw.
As an improvement being equipped with sealing ring above bearing block, for sealing every liquid, sealing ring is equipped with gland, for protecting
Shield sealing ring is not fallen off.
As an improvement being equipped with sealing ring and gland below bearing block, prevent bearing from contacting with the external world, saves lubricating oil
Leakage.
Compared with the prior art, the technical effects of the present invention are:
1, axial load, radial load and axial and radial simultaneous combined loading can be born, thus on realizing
The self-aligning capability and uniform force of price fixing ensure that upper fixed disk and lower fixed disk working face are flexibly connected, to keep two working faces complete
Full fitting, and then guarantee the flatness and depth of parallelism requirement of workpieces processing.
2, pressure sensor connection cylinder and lower fixed disk in the utility model control upper lower fixed disk pressure line by pressure
Variation.Clump weight adjustment plate surface evenness simultaneously makes lower fixed disk fall entire plane contact when contacting with workpiece, can protect processing
Part is not combining moment fragmentation.
