Upper load plate and rail system

Abstract

The invention discloses an upper bearing plate and a guide rail system. The upper bearing plate comprises two opposite baseplates and a support plate connected between side walls of the two baseplates, wherein the orthographic projections of the support plate on the side walls of the baseplate are located in the areas of the side walls of the baseplates; an open track is formed between the surface of the support plate and the side walls of the two baseplates; the extending path of the open track is shaped like a closed loop; the open track is used for allowing a rolling element to roll along the extending path; during use, the upper bearing plate is convenient for the rolling element to roll along the extending path of the open track; compared with the conventional sectional type track, the bearing plate can reduce interference to rolling of the rolling element caused by track joints, lower the resistance to motion of the rolling element and improve the smoothness of motion of the rolling element; moreover, as the upper surfaces of the baseplates are inclined surfaces, the height position of the upper bearing plate can be adjusted through the cooperation of a saddle and the baseplates.

Description

technical field [0001] The invention relates to an upper bearing plate and a guide rail system with the upper bearing plate. Background technique [0002] like figure 1 , 2 As shown, the upper bearing plate 2a forms a guide rail system through cooperation with the base 5a, the lower bearing plate, the saddle 1a, the cover bases 3a at both ends, and a plurality of rolling elements 6a. The lower end of the existing upper bearing plate 2a is provided with a lower rolling track, an upper rolling track is formed on the saddle 1a, and a connecting track is formed on the end cover seat 3a. During use, the lower bearing plate is fixed on the base 5a, the upper bearing plate 2a is located above the lower bearing plate and can slide along the length direction of the lower bearing plate, and the surface opposite to the upper bearing plate 2a is used To close the lower opening of the lower rolling track and form a lower through groove; the saddle 1a is fixed on the upper bearing plat...

AI Technical Summary

Problems solved by technology

During the rolling process of the rolling body 6a, the rolling of the rolling body 6a can be guided by using each track, but because the existing upper bearing plate 2a is only provided with the lower rolling track, and the upper rolling track is arranged on the saddle 1a , the connecting track is arranged on the end cover seat 3a, and it is easy to cause the uneven connection of the tracks due to the low assembly accuracy of the end cover seat 3a and other parts, so that the joint of the track interferes with the rolling of the rolling body 6a, so that the rolling The body 6a cannot roll smoothly, which affects the performance of the guide rail system
