AI Technical Summary

Technical Problem

The existing sliding table support structures have problems such as poor operation and complex assembly in design and assembly, especially the ball selection tolerance requirements and the rope-type support structures are not easy to assemble.

Method used

The design of base unit, slide unit, holding unit and drive unit is adopted, and the lateral roller set and elastic rubber roller absorb the assembly gap to adjust the tolerance, and the auxiliary slide is connected through the connecting rod to ensure smooth movement. The lead screw is protected by the rubber cover to reduce processing errors, and the limit anti-collision block limits the movement limit.

Benefits of technology

It realizes smooth operation of the sliding table device, simplifies the assembly process, extends the service life of the lead screw, reduces noise and improves movement stability, and prevents the lead screw from swaying and swinging.

Abstract

A connecting rod type slide table device includes a base unit, a slide unit, a holding unit and a driving unit. The slide unit is slidably mounted on the base unit. The holding unit includes two auxiliary slides, a connecting member connected between the auxiliary slides, and two lateral roller groups respectively mounted on the auxiliary slides. The auxiliary slides are respectively located on both sides of the slide unit. Each lateral roller group includes several rollers rotatably abutted against the base unit. The driving unit includes a driving member and a lead screw. Starting the driving member can make the slide unit drive the auxiliary slides to move. By holding the lead screw through the auxiliary slides, the machining accuracy can be improved and the service life of the lead screw can be extended.
