AI Technical Summary

Technical Problem

Traditional vertical motion platforms are prone to tilting when the force is uneven on both sides, which leads to increased wear and tear and jamming, affecting accuracy and even making them unable to move.

Method used

The crossbeam is raised and lowered synchronously by a left-side motion mechanism and a right-side motion module. The crossbeam is connected by a first and a second bearing, and a groove is provided on the crossbeam to achieve relative displacement and prevent jamming caused by synchronous deviation. The bearing moves within the groove to maintain the accuracy and stability of the movement.

Benefits of technology

It achieves high-precision, jam-proof vertical movement, ensuring the accuracy and smoothness of the beam movement, extending service life, and improving the system's stability and fault tolerance.

Abstract

The utility model discloses a high-precision anti-jamming vertical motion platform which comprises a left motion mechanism, a right motion module and a cross beam, wherein the left motion mechanism and the right motion module are vertically arranged, and the cross beam is arranged on the left motion mechanism and the right motion module in a crossing mode. A first bearing and a second bearing used for supporting the two ends of the cross beam are arranged on the left movement mechanism and the right movement mechanism respectively, and a waist groove capable of horizontally sliding relative to the first bearing and / or the second bearing is formed in at least one end of the cross beam. The left side movement mechanism and the right side movement module synchronously drive the cross beam to ascend and descend to achieve high-precision movement, the cross beam is connected with the left side movement mechanism and the right side movement module through the first bearing and the second bearing, and the cross beam is provided with the waist groove to achieve relative displacement with the first bearing or the second bearing. Therefore, when synchronous deviation occurs between the left movement mechanism and the right movement mechanism, the first bearing or the second bearing is utilized to move in the waist groove to prevent movement jamming, so that the accuracy and stability of the movement of the cross beam are ensured.
