Upper carrier assembly and rail system

Abstract

The invention relates to an upper bearing component and a guide rail system, and belongs to the field of guide rails. Base plates of the upper bearing component and a support plate are formed integrally; the upper surface and the lower surface of the support plate respectively form an upper guide rail and a lower guide rail which extend along the length direction of the support plate together with the inner side walls of the two base plates; the upper bearing component also comprises inner inverters fixedly connected to two ends of the support plate and outer inverters connected to the outer ends of the inner inverters; surfaces of the inner inverters are arc surfaces, are connected with the end parts of the support plate in a smooth mode, and are connected with the upper guide rail and the lower guide rail so as to form an enclosed-loop-shaped annular guide rail; a plurality of connected rolling bodies surround the annular guide rail; the upper bearing component of the guide rail system can move along the length direction of a lower bearing component, and the lower guide rail is sealed and covered by the upper surface of the lower bearing part so as to form a lower guide rail cavity body, and the upper guide rail is sealed and covered by a saddle so as to form an upper guide rail cavity body. The problems of complex production process of the upper bearing component and running instability for the guide rail system are solved, and the production process is simple, the precision is high, and the guide rail system runs stably.

Description

technical field [0001] The invention relates to the field of guide rails. Background technique [0002] With the continuous development of modern manufacturing technology, the traditional manufacturing industry has undergone tremendous changes, and numerical control technology, mechatronics and industrial robots have been more widely used in production. At the same time, the positioning accuracy, guiding accuracy and feed speed of the mechanical transmission mechanism are constantly improving, which has caused major changes in the traditional guiding mechanism. In the field of machining equipment, rolling linear guides have gradually replaced traditional sliding linear guides due to their unique characteristics, and have been widely used in industrial production. It has been widely used in various heavy-duty combined processing machine tools, CNC machine tools, high-precision EDM cutting machines, grinding machines, industrial robots and even general In industrial machiner...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the support plate and the reverser of the upper bearing assembly of some guide rail systems are integrally formed, and the processing technology is complicated and the production cost is high

At present, there are also split-type upper bearing components. The arc-shaped cavity track of the reverse part is set inside the reverser, which makes the installation of the rolling elements very complicated. Due to long-term use, it may also cause displacement of the upper bearing component, resulting in reverse rotation. The joint between the head and the support plate is not smooth, which makes it difficult for the rolling body to reverse, and the movement is not smooth, which makes the guide rail system unstable
