滚珠丝杠的一种使用方法

来源:http://www.jngongrun.com/ 日期:2022-11-23 发布人:

一般滚珠丝杠两边配2根导轨。如果不配导轨的话,中间丝杠装工装会左右摇晃。我想请问各位,滚珠丝杠我后面接的手轮控制行程,有什么低成本的方法不装导轨,能让丝杠上的工装不左右晃动吗?

Generally, two guide rails are provided on both sides of the ball screw. If there is no guide rail, the middle lead screw tooling will sway from side to side. I would like to ask you, is there any low-cost way to control the stroke of the handwheel behind the ball screw without installing the guide rail, so that the tooling on the ball screw can not sway from side to side?
主要我看滑轨也挺贵的,一套100多,左右两边就200多了。
The main thing I think is that the slide rails are also very expensive, more than 100 for one set, and more than 200 for the left and right sides.
把直线导轨换成导柱+直线轴承的形式,能省一点点;
Replace the linear guide rail with the form of guide pillar+linear bearing, which can save a little;
滚珠丝杠不装在正,装在一侧,线轨装在另一侧,可以省一根线轨。
The ball screw is not installed in the center, but on one side, and the wire rail is installed on the other side, so one wire rail can be saved.
导轨一套一百多也嫌贵。
More than 100 sets of guide rails are too expensive.
那考虑一下用圆棒导向吧。
Then consider using a round bar for guidance.
或者用比较次一点的导轨。
Or use the guide rail with a lower comparison.
实在不行底板上开个槽,丝杆螺母上搞个凸起,就当导轨用了。
It's really not feasible to make a slot on the bottom plate and a bulge on the screw nut, which can be used as the guide rail.
顺带说一下,既然你说精度不需要太高。那要再降低成本,你可以底下的大板结构改一下。你现在大板上凸出来两个长条状的块块,其持完全可以做成三个零件,因为做成一个零件的话,那铣起来加工费和材料费肯定会贵一些的。
By the way, since you said the accuracy should not be too high. To reduce the cost, you can change the structure of the big board below. Now you have two long blocks protruding from the big plate, which can be made into three parts. Because if you make one part, the processing cost and material cost will be higher.
还有一点,你既然想用导向轴+直线轴承的方式,那你得做好心理准备,设备运行起来必定会发生晃动,直线轴承和导向轴的配合没那么紧的。
Another point is that if you want to use the guide shaft+linear bearing, you must be prepared. The equipment will shake when running. The linear bearing and the guide shaft are not so tight.
用手轮图便宜的话,省心一点的用一根光轴配直线轴承,另外丝杠固定座可以自己拿轴承做。
If it is cheap to use the handwheel diagram, it is easier to use an optical shaft with a linear bearing. In addition, the lead screw fixing seat can be made with its own bearing.
承载力不大的话,可以用比较薄的直线导轨,装在丝杠正下方,一些模组都是这样用的。
If the bearing capacity is not large, a thin linear guide rail can be used to install it directly below the lead screw. Some modules are used in this way.
