The invention discloses a mechanical linkage screw, which comprises an internal screw flange, an internal screw, a front flange of an external screw, an external screw, a front control box, a rear flange of an external screw, an intermediate control box, a rear control box and a dust-proof cover, and is characterized in that the intermediate control box and a rear control box are screwed onto the internal screw through a nut and the anti-dust cover is provided. The dust cover is connected with the rear control box, and the inner screw flange is connected with the inner screw. The outer screw is sleeved on the inner screw. The front control box is screwed onto the outer screw through the nut, and the front flange and the rear flange of the outer screw are respectively installed at both ends of the outer screw. The mechanical linkage screw is equipped with several control boxes, which not only makes the overall design more compact, but also realizes the graded position adjustment of each connecting component. The structure is simple and the operation is convenient.
【技术实现步骤摘要】
一种机械式联动丝杆
本专利技术涉及一种调整位置用丝杠螺母装置，具体为一种机械式联动丝杆。
技术介绍
丝杠螺母（俗称丝杆螺母）机构是用来将旋转运动转化为直线运动，或将直线运动转化为旋转运动的执行元件，可用于位置调整、重物提升、预紧定位等场合。较常见的丝杠螺母机构都是单级传动，通过旋转丝杠或旋转螺母分别实现螺母或丝杠按照对应规格的导程进行直线运动。如果需要对多个部件进行位置调整，就要采用相应数量的执行机构进行调控。这样就产生了如下固有缺陷：（1）只能实现独立调整，不能实现联动控制，降低了工作效率；（2）多层执行机构的设计增大了整机重量，增大了调整过程的摩擦力影响，降低了数据反馈的同步性。针对上述情况，有必要设计一种能够在同一中心线上实现多级位置调控的联动丝杆装置，提高工作效率，实现多级调控机构的优化集成，减少导向环节。
技术实现思路
为了克服上述现有的技术缺点，本专利技术的目的是提供一种机械式联动丝杆，具有操作方便，结构紧凑，可实现多级位置调控的优势。为了实现上述目的，本专利技术采取的技术方案是：一种机械式联动丝杆，包括内丝杠法兰、内丝杠、外丝杠前法兰、外丝杠、前调控箱、...
