Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0050] Such as figure 1 As shown, an ultra-long lead screw mobile support mechanism of the present invention includes a drive device, a lead screw 1, a screw nut 2 and a sliding seat 3, the two ends of the lead screw 1 are fixed by a lead screw support 5, and the drive device and the lead screw 1 connects and drives the lead screw 1 to rotate, the screw nut 2 meshes with the lead screw 1 to form a screw pair, and the slide seat 3 is connected to the screw nut 2, which also includes a support frame that slides relative to the lead screw 1 to support The frame supports the lead screw 1, and the support frame slides with the sliding seat 3.

[0051]The support frame is mainly formed by a linear rail 40, a first support 41, a second support 42 and a connecting rod 43; the first support 41 is set be...

Abstract

The invention discloses a movable support mechanism for an ultra-long screw, which comprises a drive device, a screw 1, a nut 2 and a slide 3. Two ends of the screw 1 are fixed via screw bearings. The drive device is connected with the screw 1 and drives the screw 1 to rotate. The nut 2 is meshed with the screw 1 and forms a screw pair with the screw 1. The slide 3 is connected to the screw 2. The movable support mechanism further comprises a support frame capable of sliding relative to the screw 1, the screw 1 is supported by the support frame, and the support frame slides with the slide 3. The movable support mechanism has the advantages that precision is well maintained, screw wear is effectively prevented, dismantling, maintenance and replacement are facilitated, the service life of the support structure is prolonged, and the screw is guaranteed to normally operate with high precision and at high speed.

Description

technical field [0001] The invention relates to a supporting structure of a lead screw pair, in particular to an ultra-long lead screw movable support mechanism. Background technique [0002] The screw pair is a screw transmission component composed of a screw and a screw nut that can convert rotary motion into linear motion. Due to its working characteristics, it is widely used in linear actuators of machine tools. The known lead screw pair generally supports and pretensions the two ends of the lead screw through the lead screw support and the bearings in the lead screw support. However, with the increasing development of large lathes and gantry processing centers, especially processing equipment The Y-axis stroke is getting larger and larger. If the existing technical solution is still used, only relying on the support of the screw support at both ends of the screw and the pre-tensioning and pre-tightening at both ends cannot meet the application of the ultra-long screw co...
