Description
Technical field
The present invention relates to a kind of mechanism that strengthens operating desk table top flatness.
Background technology
In the production application of lathe more and more widely, progressively this operation of instead of manual of automation control, motor is as the power source of electrical appliance or various machineries in automation process, it holds a high place.
Traditional " electric rotating machine+ball-screw " feeding kind of drive on the lathe, owing to be subjected to the restriction of self structure, in feed speed, acceleration, aspect such as positioning accuracy is difficult to breakthrough raising fast, the requirements at the higher level that superhigh-speed cutting, ultraprecise processing propose machine tool feed system servo performance can't have been satisfied.Linear electric machine is directly changed into rectilinear motion mechanical energy with electric energy, without any need for the transmission device of intermediate conversion mechanism.Had advantages such as dynamicthrust is big, transmission stiffness is high, dynamic response is fast, positioning accuracy is high, haul distance is unrestricted.
In the machine tool feed system, adopting the maximum difference of the direct driving of linear motor and former electric rotating machine transmission is to have cancelled the machine driving link between (planker) from the motor to the workbench, be the contraction in length of machine tool feed driving-chain zero, thereby this kind of drive be otherwise known as " zero transmission ".Just because of this " zero transmission " mode, former electric rotating machine type of drive be beyond one's reach performance indications and advantage have been brought.Therefore the application of linear electric machine more and more widely.
Linear electric machine is a kind of calutron, in the process of its application, exist very big normal direction suction between mover and the stator, move normal tension constantly at motor and be about about 10 times of thrust, under most of occasions, this power does not wish to exist, particularly on the higher board of some required precisions, powerful normal direction suction can make the board operating desk that links to each other with electrode produce certain deformation, and this is unfavorable for the high Precision Processing process.
Summary of the invention
The purpose of this invention is to provide a kind of mechanism that strengthens operating desk table top flatness, can solve owing to existing powerful normal direction suction in the linear electric machine and make the board operating desk that links to each other with electrode produce the problem of certain deformation.
At above problem, the present invention proposes following scheme:
A kind of mechanism that strengthens operating desk table top flatness is characterized in that, comprises the fixed mechanism of some bracing pieces and bracing piece.
Preferably, described bracing piece is one.
Preferably, described bracing piece directly is fixed on the operating desk.
Preferably, described bracing piece fixed-direction is vertical with the linear electric machine direction of motion.
Preferably, the fixed mechanism of described bracing piece is some groups of screw and nuts.
Preferably, every bracing piece has the screw and nut that one group of straight line is arranged.
Preferably, described bracing piece is made of rigid material.
Preferably, described bracing piece is made by stainless steel.
Preferably, described bracing piece and operating desk contact-making surface are the plane, and after fixing, are close to mutually between two planes.
Preferably, described bracing piece is that the degree of lip-rounding cuts section bar or the I-section beam.
The mechanism of reinforcement operating desk table top flatness provided by the invention, can effectively reduce the operating desk table top degree of crook that linear electric machine normal direction suction is brought, thereby will be dropped to minimumly by the negative effect that the bending of operating desk table top brings, effectively improve performance accuracy.
