As preferably, the top of described casing is provided with case lid, and described case lid is sealed by box sealing circle mutually with casing, and described hydraulic oil inlet and oil pressure assemble projection and be located in case lid.
The method of operating of positioned at arbitrary angles lathe tools platform, carry out according to the following steps:
(1), cutter positioning:
Tool table is arranged on lathe by servomotor;
(2), measurement deviation:
Export the deviation between the positional precision mensuration of angle of revolution with assigned position by tool table, produce measurement result, i.e. error amount, measurement result is changed into the auxiliary correction data of interval error and be transferred to machine tool controller;
(3), auxiliaryly just to look after and guide:
According to error amount, looked after and guided in the following manner by auxiliary positive operation:
By machine tool controller, utilize the CNC and the PLC device that there are control instruction operation function, utilize interval error to carry out auxiliary orthofunction by drive division and follower and carry out just auxiliary;
Or,
Directly to the value of the CNC and PLC device input deviation amount that have control instruction operation function, directly finely tune;
(4), locating segmentation:
Behind location, position, split by desired location.
The drive division that this mechanism has zero clearance, high position precision, cooperation have repeatable accuracy, can ensure high gyratory directions rigidity and the hi-Fix of optional position.And when output flange axle is static (optional position), output flange axle circumferencial direction is applied pressure fixing uniformly, still can keep with just auxiliary when high load capacity.
Time output flange axle is fixed, adopt gapless drive division, because engaging the reasons such as displacement between output flange axle and follower, when output flange axle produces and makes it pivotal power, this position still can be kept motionless, and maintain high accuracy.
The location of this structure is by the even diffusion pressure of hydraulic fluid, can suppress the generation of the engagement displacement of output flange axle and the fastening anchor ear of oil pressure to greatest extent.
Effect:
1., can locate and keep maintaining static in optional position, the various number of divisions can be formed, also can do the calibration of different spacing.
(the various number of divisions but the common of output flange axle and drive division can be accomplished, because when tool size spacing changes, output shaft can accomplish miniaturization).
2., the micro-locality of instrument point of a knife controls to be realized separately by this device, even if there is absolute positional precision error (according to indexing position, the deviation of the height of working substance center and point of a knife), repeatable accuracy is high, and it is just auxiliary still can to carry out position.Nose height guiding mechanism that mechanism in the past must have can no longer need.(generally, a lot of lathe has the numerical control axle that can regulate height)
3., this tool table device continuous print that can realize cutter turns round movement, the working range that former cutter gap indexing mechanism+orthogonal 3 axle completes freely, and after employing new technology, any aligned cutting tool platform+orthogonal 2 axle can complete.
Therefore, the lathe tools platform of positioned at arbitrary angles provided by the invention and method of operating thereof, structure is simple, and angular adjustment aspect, accurate positioning, Adapter Property is outstanding.
