Semi-closed embedded guide rail module

Abstract

The invention relates to a semi-closed embedded guide rail module. The semi-closed embedded guide rail module comprises a guide rail module, a sliding module and a driving module are arranged on the guide rail module; the guide rail module comprises a base with a sliding groove. Guide rail strips are correspondingly arranged on the inner walls of the two opposite sides of the sliding groove. The two guide rail strips are respectively provided with a first ball groove. The sliding module comprises a sliding table slidably connected with the sliding groove. Second ball grooves are formed in the two sides of the sliding table respectively. Ball reversing assemblies are fixedly mounted at the two ends of the sliding table respectively; backflow grooves are formed in the two ends of the ball reversing assembly respectively; one end of the backflow groove is in through connection with the first ball groove, and the other end is in through connection with the second ball groove to form a ball circulation channel; and the two ball circulating channels are filled with a plurality of steel balls. The two guide rail strips are embedded in the inner walls of the two opposite sides of the sliding groove of the base respectively, so that the linear guide rail and the base form an embedded integrated structure, the space is saved, the installation error of the guide rail is reduced, and the straightness and the walking parallelism of the guide rail are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, and more particularly, to a semi-closed type embedded guide rail module. Background technique [0002] Linear modules are linear actuators driven by servo or stepper motors. Modular linear modules have become indispensable motion execution units in automation applications. Linear modules are commonly known as linear modules, single-axis manipulators, etc. [0003] In the prior art, the guide part of the linear module is generally assembled on the base using a standard linear guide rail, and then assembled by a lead screw, a bearing seat and a servo motor. The positioning of the linear module slider is realized by controlling the rotation of the motor. The disadvantage is that the integration is low, the assembly parts are many, the external dimensions are too large, and the cumulative error is large; the application is limited in many high-precision and high-integration equipme...
