Description
Technical field
The present invention relates to a kind of intelligent temperatures to rise thermal compensation cast mineral lathe bed, and lathe bed is using steel structure frame and internal filling
Mineral material, lathe bed laid inside cooling line and in many places mounting temperature sensor monitor feedback in real time to lathe temperature
To control system, intelligent control is carried out.
Background technology
With being constantly progressive for the relevant technologies such as numerically-controlled machine tool complete machine and parts design, manufacture, assembly and material, geometry
Error, tool wear, servo equal error ratio shared in numerically-controlled machine tool global error are gradually reduced.But Thermal Error is
One of maximum error source of precise numerical control machine will improve machining accuracy and just must effectively be compensated machine tool thermal error.
Although people just have begun to study thermal characteristic of machine tools from the 1940s, due to traditional machine tool
High not as manufacture now requires in accuracy and speed, Thermal Error accounting is not high, and due to lathe and its unit type and
The diversity of load, the complexity of structure and machine tool temperature field close thermal deformation to be influenced by many factors, therefore its research is universal
Both for specific lathe, the theory, method and analysis tool of system are not formed, this develops with current machine tool high speed high-precision
Requirement it is incompatible.
The most commonly used is carry out heat error compensation according to thermal deformation in digital control system at present.Its basic definition is artificially
It manufactures a kind of new error to go to offset or significantly weaken the initial error for currently becoming problem, passes through statistics, analysis, conclusion and the palm
The characteristics of holding initial error and rule establish error mathematic model, make one both error and initial error for caused by as possible
Numerical value is equal, direction is on the contrary, to reduce mismachining tolerance, improves Dimension Measurement precision.
Machining accuracy can be improved in heat error compensation in a certain range, helps to reduce design and manufacture cost.But it is
A method of passive and subsequent compensation, compensation range and validity have certain limitation.Improve the precision of lathe
And hot property, it is necessary in the design phase, start with from thermal characteristics, the hot rigidity for improving lathe, realize the Active thermal control of lathe.
It is primary raw material that cast mineral, which is with the particle of stonite's natural granite, leftover bits and pieces, and epoxy resin is added
For auxiliary material, the manufactured New Mineral cast article by mixing, vibratory compaction.It is a kind of replacement cast iron but better than casting
The novel energy-conserving of iron, the non-metallic composite material of environmental protection.Cast mineral is cast using room temperature, has thermal expansion similar with steel
Coefficient can well be combined with the material being cast into cast mineral；Its heat-shrinkable very little, and there is no parts
It shrinks, it is more much higher than traditional cast iron precision；Its shock absorption is 10 times stronger than traditional cast iron, especially to significantly shaking
It is dynamic, there is extremely strong damping capaicty；It is insensitive to the variation of temperature, and thermal conductivity is more much lower than metal, effectively lathe
Geometric dimension control errors are in minimum caused by heated, to ensure that the precision of lathe.
