The invention discloses a high-precision telescopic inserting and taking structure for a horizontal machining center machine tool workbench. A middle fork main body plate is located on the upper surface of a lower fork main body plate, an upper fork main body plate is located on the upper surface of the middle fork main body plate, and a connecting assembly is used for connecting the middle fork main body plate and the upper fork main body plate; the upper fork main body plate also axially moves on the upper surface of the middle fork main body plate, the movement direction of the middle fork main body plate is consistent with that of the upper fork main body plate, and the driving assembly is arranged on the lower surface of the lower fork main body plate, at least partially penetrates through the lower fork main body plate, is connected with the middle fork main body plate and is configured to drive the middle fork main body plate to move. Two-stage reciprocating motion of the pallet fork is achieved through one chain, the space size is greatly reduced, the stretching part of one chain is only one fifth of the total length, the elongation rate after long-time operation is greatly reduced, long-time stability can be kept, and the chain is matched with the long chain rack and multiple teeth, so that the service life of the pallet fork is greatly prolonged. And errors caused by low precision of the chain are reduced.
本发明公开了一种用于卧式加工中心机床工作台的高精度伸缩插取结构,中叉主体板位于下叉主体板的上表面,上叉主体板位于中叉主体板的上表面,连接组件用来连接中叉主体板、上叉主体板,上叉主体板也在中叉主体板的上表面轴向运动,且中叉主体板与上叉主体板的运动方向一致,驱动组件设置在下叉主体板的下表面,至少部分穿过下叉主体板,与中叉主体板连接,且配置为驱动中叉主体板运动。本发明使用一根链条实现了货叉两级的往复运动,大大缩小了空间尺寸,而且一根链条的拉伸部分只有其总长度的五分之一,长时间运行后的伸长率大大降低,可保持长久的稳定性,链条与尺寸较长的链齿条配合,较多齿的配合,减小了链条自身精度低产生的误差。
