Adjustable pre-pressure self-lubricating block module

The present invention relates to a slider module, and more particularly to an adjustable preloaded self-lubricating block module.

Linear slides are a mechanical transmission used in machining, semiconductor manufacturing and automation equipment. In order to reduce the linear slide to reach the critical speed, the problem of slippage occurs. Generally, a rolling body is arranged between the slider and the slide rail to prevent the glue from sliding. Ball or roller linear slides are mostly used on the market today to reduce the friction of the contact surfaces and prevent slippage.

However, when the linear slide is applied to the positioning system of the high stability and precision requirements, the vibration shock generated by the reciprocating motion of the slider must be considered, but the ball or the roller line is in the point or line contact mode due to the rolling element. The rigidity and damping are poor and the mechanical structure is relatively complicated. Therefore, if it is necessary to increase the rigidity of the linear slide and increase its damping, it is necessary to pre-stress the linear slide. The conventional preloading technique also increases the diameter of the rolling element to reduce the radial clearance between the slide rail and the slider. Reduce the runout and increase the rigidity of the linear slide.

However, the above-mentioned linear rail preloading method must be adjusted when the factory produces the linear slide rail. Once the factory chooses to set the pre-pressure, there is no The law is easy to change. Therefore, the inventors have developed a kind of adjustable preload self-lubricating block module in view of the troubles of the industry and taking a long time to carry out relevant experiments without delay.

The object of the present invention is to provide an adjustable pre-pressure self-lubricating block module, which can adjust the pre-pressure immediately according to the user's demand, and has lower processing cost and material force than the pre-pressing method of the ball and roller type linear sliding rail. The advantage of cost.

According to an embodiment of the present invention, an adjustable pre-pressure self-lubricating block module is provided that is slidably disposed on a slide rail, and the adjustable pre-pressure self-lubricating block module includes a slider and at least one pre-compacting a block and at least one adjustment member. The slider includes an open inner groove, and the open inner groove includes a first inclined surface. The pre-pressing insert is disposed in the open inner groove, and the pre-pressing insert comprises a second inclined surface and a pre-pressing surface, wherein the first inclined surface corresponds to the second inclined surface, and the pre-pressing surface of the pre-pressing insert has a gap between the sliding rail and the sliding rail A gap. The adjusting member is movably disposed on the slider and drives the pre-pressing insert to adjust the pre-pressure of one of the adjustable pre-pressure self-lubricating block modules by adjusting the gap.

According to an embodiment of the present invention, the slider further includes at least one adjusting groove, the adjusting groove is disposed on the first inclined surface, the adjusting member is screwed on the adjusting groove, and the pre-pressing block further comprises at least one latching groove The card slot is matched with the adjustment slot to accommodate the adjustment member. The adjusting member can be a screw, which has a nut, a stud and a threaded segment in sequence, and the threaded portion is screwed to the adjusting groove. The adjustable pre-compression self-lubricating block module can further comprise a snap ring, which can be accommodated in the latching groove, and the snap ring is used for the screw stud to pass through the nut of the limit screw. The adjustable pre-pressure self-lubricating block module may further comprise a bottom plate, which fixes the pre-pressing block on the slider to limit the displacement of the pre-pressing block. Adjustment The number of the groove, the adjusting member, the card slot and the click ring may be two and symmetrically disposed at the two ends of the pre-pressing block. The adjustable pre-compression self-lubricating block module may further comprise a fixed insert, the opposite pre-pressing insert is arranged on the other side of the open inner groove, and the fixed insert, the pre-pressed insert and the open inner groove form a chute, The slider is slidably disposed on the slide rail. The chute can be of the dovetail type.

Therefore, according to the embodiment and the embodiment of the adjustable preload self-lubricating block module, the second inclined surface of the pre-pressing block can be displaced relative to the first inclined surface of the open inner groove, and the preload can be adjusted. The gap between the pre-stressed surface of the block and the slide rail. When the gap is smaller or smaller and the negative gap is caused, the larger the pre-pressure of the adjustable pre-pressure self-lubricating block module can be applied to the requirement of high rigidity and high impact resistance. When the gap is larger and larger, the micro-gap is formed, indicating that the pre-pressure of the adjustable pre-pressure self-lubricating block module is smaller, which can be applied to the requirement of low damping.
