Radial positioning mechanism of arc rolling guide rail

Abstract

The invention discloses a radial positioning mechanism of an arc rolling guide rail. The radial positioning mechanism comprises a plurality of adjusting blocks symmetrically installed on the two sides of a rail, fixing blocks are arranged on the sides, away from the rail, of the adjusting blocks, fine adjustment screws are installed on the fixing blocks, and the fine adjustment screws penetrate through the fixing blocks and then abut against the sides, away from the rail, of the adjusting blocks. The adjusting blocks and the fixing blocks are all fixed to a rail mounting base, and the sides, close to the rail, of the adjusting blocks are in linear contact with the side face of the rail. According to the radial positioning mechanism of the arc rolling guide rail, the problems that in the prior art, a rail jackscrew used for radial positioning and adjusting is small in diameter, the radial positioning rigidity and strength are low, and under the action of high radial loads, the radial deformation of a rail is large, and the rotation precision is affected are solved.

Description

technical field [0001] The invention belongs to the technical field of arc rolling guide rail structures, and relates to a radial positioning mechanism of arc rolling guide rails. Background technique [0002] The arc rolling guide is a new type of rolling guide. The track of the guide is arc-shaped. The slider on the track can move in a circular arc along the guide. Multiple arc tracks can be spliced ​​into a complete ring. The slider can realize a complete circular motion, and its structure is as follows figure 1 As shown, there is a counterbore on the arc-shaped track. When in use, pass the track fixing bolt through the counterbore to fix the track on the track installation base. The arc-shaped track needs to be on the same circle when splicing. For this reason The radial position of each section of the track needs to be adjusted during installation. [0003] Due to the limitation of its own structure, the diameter of the track jacking wire used for radial positioning a...
