Description

Technical Field

[0001] This utility model relates to the field of mechanical slide table technology, and in particular to a gantry-type five-axis mechanical slide table. Background Technology

[0002] A mechanical slide is a mechanical structure that enables linear reciprocating motion. It consists of a guide rail, a slider, a drive device (such as a ball screw or rack and pinion), and a control system. It is widely used in machine tools, automated production lines, and precision testing equipment. It drives the slider to move precisely on the guide rail through the drive device. It can achieve different speeds and strokes according to requirements, and has high positioning accuracy and repeatability. It can work with other components to complete the handling, processing, and assembly of workpieces. It is a key basic component for achieving linear motion control in the fields of mechanical manufacturing and automation.

[0003] A gantry-type five-axis mechanical slide is a high-precision mechanical slide based on a gantry structure, integrating five motion axes for linkage control, enabling complex spatial trajectory motion. However, the linear guides (such as ball guides and hydrostatic guides) used in this type of slide have low precision levels, or the preload of the slide is unreasonable, which can cause the slide to jam, deviate, or crawl (periodic vibration at low speeds) when moving. Existing technologies use roller guides, where the rollers and guide surfaces are in line contact, resulting in a more uniform distribution of contact stress, reducing local deformation caused by load fluctuations, and improving the stability of the device during operation. However, the raceways of roller guides are relatively deep, and insufficient lubrication (such as dried grease) or the entry of contaminants (such as cutting fluid and iron filings) can cause sudden changes in the rolling resistance of the rollers, resulting in fluctuating movement speeds at low speeds.
