Abstract
The utility model relates to a thermal resistor type thermal elongation compensation device for a main shaft. The thermal resistor type thermal elongation compensation device comprises a database forrecording data acquired by a thermal resistor test, a main shaft temperature sensor, an automatic control device and a servomotor, wherein, the data required to be compensated in the database, that isthe extent to which each temperature growth point deforms and elongates, are acquired through the thermal resistor test; and then, based on the comparison of the main shaft temperature detected by the main shaft temperature sensor and the data in the database, the servomotor, under the control of the automatic control device, adjusts the position of the main shaft. By use of the main shaft thermal elongation compensation technology, the utility model improves the machining precision of a machine tool in an economical and remarkable manner, and therefore is worth to certain degree popularization and application.
Description
Technical field
The utility model belongs to the Digit Control Machine Tool field, particularly relates to a kind of main shaft thermal distortion compensation device.
Background technology
Main shaft is in operation process, and servomotor, bearing and other moving component can produce heat because of friction, loss etc.If heat can not in time distribute and discharge, then cause the main shaft bearing burn probably, main shaft even ram produce thermal stretching, have a strong impact on machine finish then.Therefore, numerous lathe manufacturer all is to the cooling that circulates of the mode of spindle bearing holder overcoat by thermostatical oil, makes the heat of the overwhelming majority in the spindle operation process take body out of with recycle oil, intercept and ram between hot transfer route, to reduce thermal deformation.But it is fast or can't cool off and put in place because of conduction of velocity that perfect again cooling also still has part position heat, causes heat in time not discharge, and makes main shaft and ram produce thermal deformation.In order further to solve the influence of this part thermal deformation of main shaft, so the device that need compensate the main shaft thermal deformation to precision.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of thermal resistance type main shaft thermal stretching compensation arrangement, to improve machining accuracy of NC machine tool.
A kind of thermal resistance type main shaft thermal stretching compensation arrangement, comprise that the experiment of record thermal resistance obtains database, main shaft temperature sensor, automaton and the servomotor of data, need offset data in the database obtains by the thermal resistance experiment, is about to the anamorphic stretching amount of each temperature increase point; Main shaft temperature and the contrast of the data in the database that detects according to the main shaft temperature sensor then is by the position of automaton control servomotor adjustment main shaft.
Described temperature sensor is installed on the pulley support.
Beneficial effect
The utility model is by main shaft thermal stretching compensation technique, and not only economy but also improved the machining accuracy of lathe significantly had certain promotion and application and is worth.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
A kind of thermal resistance type main shaft thermal stretching compensation arrangement, comprise that the experiment of record thermal resistance obtains database, main shaft temperature sensor, automaton and the servomotor of data, need offset data in the database obtains by the thermal resistance experiment, is about to the anamorphic stretching amount of each temperature increase point; Main shaft temperature and the contrast of the data in the database that detects according to the main shaft temperature sensor then is by the position of automaton control servomotor adjustment main shaft.
Concrete axis system, the part of heating is in the belt pulley coupling part.From the part of the main distortion in position of heating part at belt pulley 2 thermal radiation fields, this part is referred to as available heat elongated portion 9 to nut seat to front-end of spindle, therefore temperature sensor 8 is installed on the pulley support, can directly measure the temperature of heat generating spot like this, carry out the precision that corresponding compensation guarantees machine cut then.
