Abstract
The invention relates to a cooling device for a linear motor machine tool guide rail. The cooling device comprises a worktable, the machine tool guide rail, stator coils, rotor magnets and refrigerator evaporating pipes, the worktable suspends above the machine tool guide rail through magnetic force, a gap is formed between the worktable and the machine tool guide rail, the stator coils are fixedly mounted on two side faces of the machine tool guide rail, the rotor magnets are fixedly mounted on the inner side face of the worktable, and the refrigerator evaporating pipes are embedded into the machine tool guide rail and the worktable and next to the stator coils and the rotor magnets. By the aid of the technical scheme, the temperature can be effectively controlled within a proper range, and precision reduction due to thermal deformation of the guide rail caused by overheating of the coils is prevented.
Description
Technical field
The present invention relates to the heat abstractor field, be specifically related to a kind of heat abstractor for the linear electric motors machine tool guideway.
Background technology
Along with the development of the advanced manufacturing technologies such as superhigh-speed cutting, ultraprecise processing, the lathe property indices has been proposed to more and more higher requirement.Particularly the servo performance of Machine Tool Feeding System is had higher requirement: very high driving thrust, fast feed speed be arranged and high quick positioning precision is arranged, to this, the relevant expert has also successively proposed directly to drive with linear motor the scheme of platen, " the linear motor heat " that the European Machine industry starts rapidly both at home and abroad.
Although linear motor can well meet the modern requirement of above-mentioned lathe in theory, but the direct poor lathe inside in radiating condition due to linear motor, the heat that its primary and secondary winding produces in carrying out the electromagnetic energy transfer process, very easily make temperature T raise, and the rising of temperature T will cause that again motor winding resistance value R increases, at this moment constant for guaranteeing driving force output, will increase its electric current I, the increase of electric current I will make again temperature T raise conversely, thereby form the positive feedback process of vicious circle.Winding, iron core due to linear motor just is attached on machine tool guideway again, and its result will seriously cause the machine tool guideway thermal deformation.So, after Machine Tool Feeding System adopts linear motor to drive, resolving its heat dissipation problem is a vital step.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, a kind of heat abstractor for the linear electric motors machine tool guideway is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
