Problems solved by technology

[0005] However, the above-mentioned ball screw needs to be assembled with a special tool, that is, the sealing member is firstly housed in the receiving spot facing hole, and then the nut and the spacer are assembled on the bolt shaft. Finally, a Round rods (press-in jigs) are sequentially inserted into the through holes respectively connected to the receiving spot facing holes to push the sealing member received in the receiving receiving spot facing holes to the other nut spot facing. A sealing member must be pressed into the fixture to be connected to the cooling channel of the nut, and the assembly efficiency is limited.

Abstract

A double-nut cooling ball screw includes two nuts threadedly engaging with a threaded shaft and having connecting end portions facing toward each other and cooling channel assemblies in fluid communication through coupling holes in the connecting end portions, and a spacer interposed between the connecting end portions and having notched recesses for accommodating guiding assemblies. Each guiding assembly is rotatable relative to the nuts between a non-stored position for facilitating fastening thereof, and a stored position to be concealed between the nuts.

Description

technical field [0001] The invention relates to a ball screw, in particular to a double-nut cooling ball screw. Background technique [0002] A cooling type double nut disclosed in Taiwan Patent No. M444445, which mainly includes a front nut assembly including a plurality of spaced cooling passages, and a rear nut assembly including a plurality of spaced cooling passages Components, a pre-compression sheet tightly assembled between the front and rear nut assemblies, and a plurality of cooling passages respectively assembled on the front and rear nut assemblies and the corresponding pre-compression sheets Through the middle sealing member at the junction of the flow holes, the cooling liquid can circulate through the cooling channels of the front and rear nut assemblies, so as to achieve the beneficial effect of cooling the front and rear nut assemblies. [0003] However, the above-mentioned cooling type double nuts are not easy to assemble, that is to say, the middle sectio...
