Abstract

The invention discloses an embedded-guide-rail linear sliding table with four-column arc type grooves. The sliding table comprises an aluminum profile base and a sliding base, the sliding base is slidably installed in the aluminum profile base, the sliding base is made of a high-strength aluminum alloy material, two square groove openings are formed in the inner walls of the two sides of the aluminum profile base, two square groove openings are formed in the two sides of the sliding base, the square groove openings at the two sides of the aluminum profile base and the square groove openings atthe two sides of the sliding base are equal in spacing, structures of the two sides of the aluminum profile base and the sliding base are symmetrical, and embedded guide rails are fixedly installed in the square groove openings. According to the sliding table, the circular arc type grooves greatly reduce the differential sliding movement amount of steel balls, when prepressing of the steel ballsis enlarged, a four-column arc type structure is obviously smaller than a two-column Gothic type structure in rolling resistance, the precision is improved, the service life of a rolling body is prolonged, and the sliding table is particularly suitable for large-load and high-precision application occasions.

Description

technical field [0001] The invention relates to the technical field of precision linear transmission, in particular to a linear slide table with embedded guide rails with four rows of circular arc grooves. Background technique [0002] The electric slide table is also called a single-axis manipulator, a linear module, and a linear actuator. It is a linear actuator driven by a servo or stepping motor, and is an indispensable motion execution unit in automation equipment. As the basic part of the transmission component for guidance, the linear slide table is the core component of the electric slide table and other linear transmission components. [0003] There are mainly two technical solutions for the linear guide part of the existing electric slide table. The first is to use standard guide rails as the precision guide structure of the electric slide table. The second is to process a Gothic steel ball on the inner side of the aluminum base. The rolling groove is relatively ...
