Description

[0001] LINEAR STAGE INCLUDING DAMPING UNIT [0002]

The present invention relates to a linear stage, and more particularly to a linear stage including a damping unit for absorbing a collision of a slider so that the slider does not come off the rail due to malfunction.

Generally, the linear stage is constituted by an LM guide rail fixedly installed on one side of a stone quartz plate and a stone quartz plate, and a slider sliding along the LM guide rail, and is a device for placing a conveyed object on a slider and reciprocating the conveyed object in a straight line .

Here, the slider is designed to perform a linear reciprocating motion within a prescribed range under the control of various position detecting sensors and a control unit for applying a control signal. However, due to contamination of the position detecting sensor or malfunction of other operating parts, The damping unit is fixed to the end of the stone column through the fixing piece so that the slider does not deviate out of the prescribed range.

On the other hand, when the slider collides with the damping unit due to a malfunction of the slider, the damping unit absorbs the shock. However, there is a problem that as the damping unit is directly fixed to the stone quarry, the impact is transmitted to a part of the quarry cabinet to which the damping unit is fixed, eventually falling off the stone quarry.

Therefore, even if the performance of the damping unit is satisfied, there is a problem in that the damping unit can not perform the function of the damping unit because the damping unit can not be firmly fixed to the stone ring. In addition, in the related art, there is a risk of a safety accident because an operator may be injured by a damping unit which is separated from a stone quartz at a high speed.

In order to solve the above problems, it is an object of the present invention to provide a linear stage including a damping unit which can be firmly fixed without being detached from the precious stones by the impact of the slider.

In order to achieve the above object, according to an embodiment of the present invention, A rail fixed to the stone block through a plurality of fasteners; A slider slidably moving along the rail; And a damping unit fixed to a part of the rail; . &Lt; / RTI >

The damping unit includes at least one damper; And a support plate fixed to the damper and fixed to the end of the rail through a fastening piece.

And a fixing block coupled to a groove formed on an upper surface of the stone stone table, wherein the supporting plate is fixed to the fixing block through a fastening piece.

And the support plate is fixed to the stone block through a fastening piece.

And a cover member spaced from the upper side of the stone pot and fixed to the upper end of the support plate.

And the rail is indirectly fixed to the stone hearth through a guide member made of stone fixed to the upper surface of the stone stone pot.

And a fixing block coupled to a groove formed on an upper surface of the guide member, wherein the supporting plate is fixed to the fixing block through a fastening piece.

As described above, in the present invention, there is an advantage that the slider can be prevented from being damaged when the damping unit is repeatedly collided.
