The specific embodiment
Each preferred embodiment of the present invention below will be discussed.But it will be appreciated by those skilled in the art that herein detailed description not as limiting the scope of the invention, the present invention also can be achieved by modification or other equivalent way of following each embodiment.
Fig. 1 is the structural representation of two-dimension moving platform device according to an embodiment of the invention.As shown in Figure 1, two-dimension moving platform can comprise: rotating shaft, linear axis and feedback transducer etc.
Rotating shaft is fixedly installed on the moving plate of linear axis.Interior of rotating shaft is a hollow structure, so that whole tubing can pass.Particularly, tubing inserts interior of rotating shaft from the rotating shaft left end, and passes from the collet of rotating shaft tubing grasping system.In one example, can realize clamping and unclamping the function of tubing by the pneumatic system of interior of rotating shaft.Interior of rotating shaft can be provided with the non-maintaining direct driving motor of high-performance.Because motor is taked the directly design of driving, can omit reduction gearing etc., so can reach the high acceleration and the high accuracy of rotating shaft.The high speed rotation of direct driving motor drives the tubing rotation.
In another embodiment of the present invention, the two-dimension moving platform device also can comprise tubing protection flexible pipe, is used for protection tubing when automatic feed.Tubing is installed flexible pipe and is installed on the hose rack, and hose rack can be fixed on the moving plate of linear axis by for example screw.
Fig. 2 illustrates an example of linear axis.As required, linear axis can comprise the suitable components that is selected from down in the group: the hard limited block of machinery, guide rail, side plate, linear electric motors, grating chi, grating ruler reading head, slide block, photoelectric limit switch, the moving plate of linear axis etc.
Drive slide block by linear electric motors, make slide block, thereby drive the moving firm and hard existing rectilinear motion of the linear axis of fixedlying connected with slide block along the line slideway straight reciprocating motion.Because linear electric motors directly drive and have saved middle transmission link, therefore can realize high acceleration and high accuracy, and can reduce wear, noise etc.
Two-dimension moving platform device of the present invention also comprises the feedback transducer of feedback slide block movement position, comprises the closed grating chi and the corresponding grating ruler reading head that are fixed on the line slideway side.In one example, can adopt high-resolution gration chi and high-precision encoder position feedback to realize the control of full cut-off ring.
In addition, two-dimension moving platform device of the present invention also can comprise photoelectric limit switch, and this photoelectric limit switch is a closed type.When slide block movement surpassed the precalculated position, photoelectric limit switch was opened and is made slide block no longer move on.In one example, it is spacing firmly also can on the position after each electronic limit switch omits a machinery to be set, so that stop platform to continue motion.
In another example of the present invention, can side plate be set in the both sides of the moving plate of linear axis.The magnetic field that side plate can effectively shield motion platform and produced, thus the influence of motor flux leakage reduced significantly to processing work.
In addition because support laser cutting chance uses the wet processing technology of cutting, therefore can linear axis and rotating shaft be set to waterproof sealing structure, enter its inside to prevent water mist etc.Preferably, can be configured both its waterproof sealing grade is reached more than the IP65.
This two-dimension moving platform device not only can be applied in the tubing laser cutting machine, but also can be applied in the measurement device of pipe material product.Compare with the motion platform that is driven by electric rotating machine, this platform provided by the present invention has the higher speed of service and precision.
